GENERAL CHARACTERISTICS

Motor compressor unit.

The new version of motor compressors groups has been designed in order to meet the requirements of the medium-high

power of the industrial refrigeration installations.

These motor compressors groups use NH3 as refrigerant, which is high energetically efficient and environmentally

friendly. They can be installed inside the rooms (machine room).

The products range is divided in thirteen sizes with a nominal refrigeration power range from 310 to 2300 kW. The

units are fitted with the standard equipment with the possibility of adding a wide range of option items, which allows us

to adapt our products to the requirements of the different designs of installations.

Each unit is fitted with the following standard equipment: a screw compressor WRV; an electric motor IP23; an

horizontal oil separator; a discharge line fitted with manual valve and check valve; a suction line fitted with filter, a

manual valve and a check valve; an oil circuit fitted with an oil pump and an oil cooler by thermosyphon. These main

elements will be delivered together with an oil charge.

The superfeed system is a very important option, because it increases considerably the efficiency of the unit energy.

All our units are factory aligned and with the oil circuits previously tested, in order to allow a quick and safe

installation.

Description of components.

1.- Compressor. It is an oil flooded type, rotary and positive-displacement machine, fitted with a capacity control of

10 100%. The compression process is made by a housing and a gearing set, which consists on two helicoidal type

rotors (a four lobes male rotor and a six holes female rotor). This gearing set allows the gas to go from a suction door to

a reducer size discharge door.

There are three types of

compressors:1) WRV type, which

is available in six different sizes

and each one has got an Vi rate or a

set volumetric rate.2) WRVi type

which is available in six different

sizes whose Vi volumetric rate can

be easily modified between 2,2

5,0, by changing the size of the

compressor discharge outlet. 3)

The WRVH type is applied to the

previously mentioned twelve

models. It can work with pressures

up to 24 bars and will be used for

working at condensing

temperatures over 45 ºC.

2.- Electric motor. It is a

triphasic, low voltage machine,

fitted with: a squirrel-cage rotor, an

internal refrigeration system 400 V, 50 Hz, a class B insulation, an IP23 protection device according to the standard EN

60034 - Part V, construction shape according DIN IEC 34, IM B3, an IP55 protection device of the terminal box.

3.- Oil separator. It is a receiver, built according to category IV, design pressure of 21 bar, according to the pressure

equipment directive PED 97/23/CE. It meets two important functions: the first and most important one is to separate

oil from the discharge gas. It makes it in two steps:

Step 1: Via a primary separator, that allows achieving an efficiency level up to 50 ppm.

Step 2: Via a secondary separator, which uses coalescent filters that allows achieving an efficiency level up to 5 ppm.

The oil separator performs the second function of being the metallic structure on which is support the GMT unit. This

structure consists on two legs and both metallic supports corresponding to the motor and the compressor.

The separator is fitted with two sight-glasses located on its primary area and one sight-glass located on its secondary

area. It is also equipped with two oil heating resistors and the oil charge. On one of its side, there is a removable cap to

replace the coalescent filters when they lose separation efficiency

4.- Oil circuit. It is necessary to check the good quality of the oil in order to ensure the correct operation of the

compressor. The oil shall be clean and with the proper temperature so that it will get the required viscosity (when

entering the compressor) to perform correctly the functions of injection, lubrication and control capacity.

Main components:

4.1.- Suction line of the oil pump. It consists on a valve and a filter fitted with grid of 100 for the

factory-test and another filter of 500

for its shipment.

4.2.- Oil motor pump. It is a gear

pump, formed by a rotor, an idler gear

and a half moon which has been fixed

inside its housing. Thus, there are only

two moving parts inside the oil motor

pump. Since the rotor is in gear with the

idler gear, the power applied to the

rotor is transmitted to the idler gear.

This pump has been designed taking

into account the requirements of the

compressors used in the refrigeration

area.

4.3.- Discharge line of the oil

pump. Connect the discharge line of

the oil pump to the oil cooler. The

discharge line is fitted with a stop valve.

4.4.- Oil bypass line. Its function is

to return to the separator, the excess of

oil flow that has been pumped by the oil pump. This excess is determined by keeping a pressure differential of

2,8 bars between the oil manifold pressure and the oil separator pressure. This line is fitted with a stop valve

and a regulating differential valve.

4.5.- Oil cooler. These coolers are specially designed for maritime and industrial refrigeration of oil. An oil

cooler is cooled by liquid NH3. It uses the thermosyphon system and operates with tubes bundle. It has a

compact design and is very light. It is necessary to extend the lifetime of the compressor and it operates as

follows: It cools the oil at 50 ° C to keep perfect conditions to lubricate the compressor.

4.6.- Oil return line. The oil that has been separated by the secondary separator should be incorporated into

the oil circuit, via the oil return line. This line connects the area of the secondary separator with the suction

line, by using stop valve, filter, needle valve and pipe.

4.7.- Line that connects the oil cooler to the micronic filter. It consists of a stop valve. .

4.8.- Micronic filter. Its function is to prevent metal particles and impurities to return to the compressor. It is

fitted with a removable cap in order to replace the filter with a new one, when necessary.

4.9.- Line that connects the micronic filter to the oil collector. It consists of a stop valve and a relief

valve.

4.10.- Oil collector. It distributes the oil in the compressor, through the injection connections, the lubrication

of front bearings and shaft, the lubrication of the rear bearings and the supply of the capacity control. It is also

fitted with a pressure connection and an oil injection temperature probe of 4-20 mA.

Page 7: Technical Guide for Screw Compresso Packages easy definition in Ammonia HW-12

4.11.- Capacity control system. It consists of a four-ways valve and four tubes, one oil connection, oil

return, charge and discharge valves.

5.- Coupling. It is a rigid type, made of steel sheets, which can absorb angular misalignment between 1 º and 1.3 º per

sheet, axials between 2 and 2.6 mm. and radials between 2 to 2.5 mm., depending on the model.

6.- Coupling protection device. It is made of aluminium and prevents access to moving parts of the group.

7.- Suction line. It consists of a stop valve, a check valve and a filter fitted with a grid of 150. It is also fitted with a

connection for capacity control, a connection for oil return, a connection for low pressure, a connection for a free valve

and a blind device to capture the suction temperature.

8.- Discharge line. It consists of a check valve and a stop valve.

9.- Set of safety valves. It consists of two safety valves placed in parallel on the oil separator, which have been set

at 21 bar, a safety valve mounted on the oil cooler and located on the side of the tubes also set at 21 bar and a relief

valve mounted in the oil cooler and located on the shell side. All of them led to a common collector.

10.- Set of automatisms. Formed by a manifold, in which four gauges, three pressure probes of 4-20 mA and four

stop valves are integrated. It is also fitted with an oil level pressure switch and

a twice high pressure switch with a single output. Three temperature probes of

4-20 mA, to measure the temperature of oil, which is going to be injected in

the compressor, the oil temperature in the oil separator and the discharge

temperature.

Mechanical elements as optionals.

s.- Superfeed. It is an option that involves an increase of the refrigeration capacity.

This increase is higher than the one of the absorbed power, which means an increase of

the efficiency of the group. It can be used for two reasons: 1) to increase the efficiency of

the group and 2) to reach a certain output without increasing the size of the compressor.

It consists of a stop valve (4), a check valve (3), a filter (1) and a thermowell (2) for

measuring temperature.

scr.- Superfeed with regulating valve. It is a complement of the Superfeed option,

described in the previous paragraph. It will be used when

there are several groups working in parallel in the same

installation. In this way, when a group reduces its capacity,

(the superfeed intermediate pressure comes close to the

suction pressure), this option will prevent losing

performance and efficiency in both groups and it will allow

operating at 100% capacity. To perform this function, it is

fitted with the following components: filter (1), check valve

(2), thermowell to take temperatures (3), pilot regulation

(4), regulating valve of differential pressure (5) and stop

valve (6), piping, low pressure connection.

mcv.- Motor activated by a variable frequency

drive between 1500 and 3000 rpm. This option can be used: 1) To start the compressor, via a controlled variation

of the frequency. 2) To improve the efficiency of the group with part load. It consists of the replacement of the standard

motor, described in Section 2 on page 5, with a motor fitted with NDE insulated bearing and reinforced wiring

insulation.

m +.- Oversized motor. This option is similar to that described in the previous section, except that we are located in

the area of red characters in the chart and the absorbed power is greater than the one provided by the standard motor.

Therefore, we should choose this option m+, to increase one size the standard motor.

__hz .- Operating with the variable frequency drive > 50 Hz. Depending on the group, the working point and

the operating maximum frequency, it may be necessary to change the oil separator, oil cooler, Ø of piping, oil pump,

electric motor, to use this option. Therefore, consult it before ordering it.

eaw .- Oil cooling by water. This option uses water to cool oil, via a cooler which has been designed for this

purpose.

eai .- Oil cooling by injection. This option ignores the cooler and replace it with an injection of NH3 to a

connection that has the compressor casing. Is made through a

solenoid valve and a thermostatic valve which controls the

discharge temperature.

tra .- Oil thermoregulation. This option allows

maintaining at all times the oil temperature controlled and

Page 9: Technical Guide for Screw Compresso Packages easy definition in Ammonia HW-12

therefore its optimum lubrication conditions. To obtain this situation, it is necessary to install an oil bypass (4), which

starts in a "T" connection (2), and ends in a three-ways valve (1), which keeps the oil injection temperature controlled.

This option also involves a change of location of the safety valve (3) oil cooler side shell.

dcc .- Twin connections. This option is used when a group is designed to serve multiple services at different times.

This option modifies two elements: A) The suction line is modified by adding a “T” connection (3) and another stop

valve (4). The rest of the elements such, as the filter (1), the check valve (2), and the stop valve (5) are not changed. B)

The discharge line is modified by adding a "T" connection (2) and an angle

stop valve (3). The rest of the elements such as the check valve (1) and the

angle stop valve (4) are not changed.

pam .- Marine

atmosphere paint. This

option is used for units

located outdoors. It consists

of:

1. The IP23

protection standard motor is replaced with an IP55 protection

motor.

2. The welding of the metal sheets of the separator, motor support, compressor support, unit legs shall be

continuous welding and not by segments.

3. The separator and its metal sheets, the supports and the legs will be treated with a blasting procedure of 5

to 2 ½ grade.

4. Paint as follows:

a. Apply an epoxy primer coating with 60% of Zinc powder. Thickness: 60 microns.

b. Then, apply an anti-corrosive intermediate coating of epoxy-polyamide. Thickness 100 microns.

c. Finally, apply a polyurethane-acrylic enamel. Thickness: 30 microns.

apc .- Condensing high pressure. If in the design of the installation, it has been considered the possibility of

working at condensing temperatures between 39 and 45 º C and since part loads are not accepted in these cases, it is

necessary to equip the unit with the option apc. This option involves installing one oversized oil cooler and the

appropriate electric motor for working at the above mentioned temperatures.

HOW TO SELECT A UNIT

In the section “Technical data and performance of the unit” the charts show the refrigerating capacity, total

absorbed power and COP of the units, depending on their evaporating and condensing temperatures.

1. All values of charts, included in this technical manual, have been obtained as the result of using the refrigerant

R717.

2. The values of the performance charts have been obtained as the result of considering a loss of charge in the

suction line of 0 bar. With other values of loss of charge, it is necessary to use the correction factor of FAP.F.

for refrigerating capacity and the correction factor FAP.A. for the absorbed power. Both factors are indicated in

CHART 1.

3. The values of the performance charts have been obtained as the result of considering a loss of charge of 0,15

bar. With other values of loss of charge, it is necessary to use the correction factor FDP.F. for the refrigerating

capacity and FDP.A. for the absorbed power. Both factors are indicated in CHART 2.

4. The values of performance charts have been obtained as the result of considering a useful superheat of 0 ºC.

With other useful superheat values, it is necessary to use the correction factor FRUP.F. for the refrigerating

capacity and FRUP.A. for the absorbed power. Both factors are indicated in CHART 3.

5. The values of performance charts have been obtained as the result of considering a total superheat of 0 ºC. With

other total superheat values, it is necessary to use the correction factor FRTP.F. for the refrigerating capacity

and FRTP.A. for the absorbed power. Both factors are indicated in CHART

6. The values of the performance charts have been obtained as the result of considering a subcooling of 3 ºC. With

other subcooling values, it is necessary to use the correction factor FSP.F. for the refrigerating capacity and

FSP.A. for the absorbed power. Both factors are indicated in CHART 5.

7. Use the chart “Sound levels” for the acoustic checking.

Example nº1 of how to select a unit.

Select a unit suitable for supplying a refrigerating capacity of 690 kW under the following conditions:

Evaporating temperature:-11 ºC

Condensing temperature 35 ºC

Consider also that:

The loss of charge, calculated for the suction line, will be of 0,11 bar.

The loss of charge, calculated for the discharge line to the condenser, will be of 0,15 bar.

The evaporators installed inside the rooms will be flooded type and therefore the useful superheat will be of 0

ºC.

Owing to the big distance between the rooms and the compressor, the total superheat will be of 2º C.

This installation will be fitted with a liquid receiver, that is the reason why the subcooling will be of 0 ºC.

Page 57: Technical Guide for Screw Compresso Packages easy definition in Ammonia HW-12

According to the requested refrigerating capacity and after checking the chart “Technical data of the Standard

unit”, select the model 710 whose denomination will be “GMT HW 710 -12” .

For this unit model and according to the chart “Performance of the unit with optimal Vi”, we obtain the following

data:

Refrigerating capacity 738,8 kW

Total absorbed power 198,3 kW

COP 3,73

If the values of loss of charge, superheat and subcooling are different from those indicated in the chart “Technical

data of the Standard unit”, it is necessary to use the following correction factors:

Chart 1, for a loss of charge in the suction line of 0,11 bar, the correction factors are FAP.F. = 0,96 and FAP.A.

= 0,99.

Chart 2, for a loss of charge in the discharge line of 0,15 bar, the correction factors are FDP.F. = 1,00 and FDP.A.

= 1,00.

Chart 3, for a useful superheat of 0 ºC, the correction factors are FRUP.F. =1,00 and FRUP.A. = 1,00.

Chart 4, for a total superheat of 2 ºC, the correction factors are FRTP.F. = 0,99 and FRTP.A. = 1,00.

Chart 5, for a subcooling of 0 ºC, the correction factors are FSP.F. = 0,99 and FSP.A. = 1,00.

So, from the previous data we obtain the following results:

Refrigerating capacity = 738,8 x 0,96 x 1,00 x 1,00 x 0,99 x 0,99 = 695,1kW

Total absorbed power =198,3 x 0,99 x 1,00 x 1,00 x 1,00 x 1,00 = 196,3 kW

COP = 667,1 / 194,5 = 3,54.

At this moment of the selection procedure, it is possible to use the option superfeed and apply it to a smaller model than

the previous one. According to the chart “Technical data of the standard unit” the suitable model is “GMT HW

650 -12”.

For the selected model and according to the chart “Performance of the unit with optimal Vi” we obtain the

following data:

Refrigerating capacity 761,5 kW

Total absorbed power 190,1 kW

COP 4,01.

The correction factors are the same than the ones mentioned above, and therefore the definitive data of the unit are:

Refrigerating capacity = 761,5 x 0,96 x 1,00 x 1,00 x 0,99 x 0,99 = 716,5 kW

Total absorbed power =190,1 x 0,99 x 1,00 x 1,00 x 1,00 x 1,00 = 188,2 kW

COP =716,5 / 188,2 = 3,81.

The efficiency obtained with the second selection is 7,9% higher than the one of the first selection.

As it states on the price list catalogue, the cost price of the second unit is 3,3 % lower (superfeed incl.) than the one of

the first unit.

The extra-cost of fitting the unit with the option superfeed has not yet been analyzed. If this extra-cost exceeds 3,3%, it

will be necessary to analyze the amortization terms.

According to the data that have been obtained previously, the group to be selected is “GMT HW 650 -12 s”. The

following data of the group shall also be set: if the motor needs an option item or not and the sound pressure levels.

.

57

Page 58: Technical Guide for Screw Compresso Packages easy definition in Ammonia HW-12

To know the motor type to be used for this application, see chart “How to select the motor size”. Then, select a cell

of the chart according to the unit data: the unit model (650), the evaporating temperature (-11 ºC) and the condensing

temperature (35 ºC). If there is an m in the selected cell, that means, that we need a nominal motor type.

The chart “Sound levels” shows the values of sound pressure levels in dBA, which have been measured at 1 meter high

and 1, 5 and 10 meters around the unit. In this case, the maximum level that has been measured at 1 meter around the

unit, is of 86 dBA.

Therefore, the selected unit is GMT HW 650 -12 s and has got the following data:

Refrigerating capacity 716,5 kW.

Total absorbed power 188,2 kW.

COP 3,81.

Maximum sound pressure level at 1 meter around the unit: 86 dBA.

Example nº 2 of how to select a unit.

Select a unit suitable for supplying a refrigerating capacity of 950 kW under the following conditions

Evaporating temperature -12 ºC

Condensing temperature 45 ºC

Consider also that:

The loss of charge, calculated for the suction line, will be of 0,10 bar.

The loss of charge, calculated for the discharge line, will be of 0,20 bar.

The evaporators installed inside the rooms will be flooded type and therefore the useful superheat will be of 0

ºC.

The total superheat will be of 1º C.

This installation will be fitted with an air condenser, therefore the subcooling will be of 3 ºC.

In order to obtain the requested refrigerating capacity and according to the chart “Technical data of the Standard

unit”, select the unit model 1060 whose denomination will be “GMT HW 1060 -12”.

The condensing temperature requested for this group is not included in the chart “Performance of the unit with

optimal Vi”. To find this information, see chart “Performance of the unit with optimal Vi and fitted with

condensing high pressure”, in which the following data are included:

Refrigerating capacity: 991,3 kW

Total absorbed power: 356,3 kW

COP 2,78

If the values of loss of charge, superheat and subcooling are different from those indicated in the chart “Technical

data of the Standard unit”, it is necessary to use the following correction factors:

Chart 1, for a loss of charge in the suction line of 0,10 bar, the correction factors are FAP.F. = 0,96 and FAP.A.

= 0,99.

Chart 2, for a loss of charge in the discharge line of 0,20 bar, the correction factors are FDP.F. = 1,00 and FDP.A.

= 1,00.

Chart 3, for a useful superheat of 0 ºC, the correction factors are FRUP.F. =1,00 and FRUP.A. = 1,00.

Chart 4, for a total superheat of 1 ºC, the correction factors are FRTP.F. = 1,00 and FRTP.A. = 1,00.

58

Page 59: Technical Guide for Screw Compresso Packages easy definition in Ammonia HW-12

Chart 5, for a subcooling of 3 ºC, the correction factors are FSP.F. = 1,00 and FSP.A. = 1,00.

So, from the previous data we obtain the following results:

Refrigerating capacity = 991,3 x 0,96 x 1,00 x 1,00 x 1,00 x 1,00 = 951,6 kW

Total absorbed power =356,3 x 0,99 x 1,00 x 1,00 x 1,00 x 1,00 = 352,7 kW

COP = 951,6 / 352,7 = 2,70.

At this moment of the selection procedure, it is possible to use the option superfeed and apply it to a smaller model than

the previous one. According to the chart “Technical data of the standard unit” the suitable model is “GMT HW

940 -12”.

For the selected model and according to the chart “Performance of the unit with optimal Vi and fitted with the

following options: superfeed and condensing high pressure” we obtain the following data:

Refrigerating capacity: 1053,0 kW

Total absorbed power: 326,6 kW

COP 3,22.

The correction factors are the same than the ones mentioned above, and therefore the definitive data of the unit are:

Refrigerating capacity = 1053,0 x 0,96 x 1,00 x 1,00 x 1,00 x 1,00 = 1010,9 kW

Total absorbed power =326,6 x 0,99 x 1,00 x 1,00 x 1,00 x 1,00 = 323,3 kW

COP =1010,9 / 323,3 = 3,13.

The efficiency obtained with the second selection is 15,8% higher than the one of the first selection.

According to this energy efficiency data, select the second unit model “GMT HW 940 -12 s apc” which is fitted with

superfeed s and condensing high pressure apc.

Then, set some data such as if the motor needs an option item or not and the sound pressure levels.

The chart “Performance of the unit with optimum Vi and fitted with the following options: superfeed

and condensing high pressure-apc” shows the following data:

Refrigerating capacity 1051,7 kW

Total absorbed power 322,4 kW

COP 3,26.

Apply the correction factors, that have been set previously to obtain the following data:

Refrigerating capacity = 1051,7 x 0,96 x 1,00 x 1,00 x 1,00 x 1,00 = 1009,6 kW

Total absorbed power =322,4 x 0,99 x 1,00 x 1,00 x 1,00 x 1,00 = 319,2 kW

COP =1009,6 / 319,2 = 3,16.

The motor must use this referred to in apc option.

The chart “Sound levels” shows the values of sound pressure levels in dBA, which have been measured at 1 meter high

and 1, 5 and 10 meters around the unit. In this case, the maximum level that has been measured at 1 meter around the

unit, is of 85 dBA.

Therefore, the selected unit is GMT HW 940 -12 s apc and has got the following data:

Refrigerating capacity 1009,6 kW.

Total absorbed power 319,2 kW

COP 3,16.

Maximum sound pressure level at 1 meter around the unit: 85 dBA.
