Parallel OperationA parallel compressors installation, with common suction line and common discharge line, give reduced operating cost through greater control of capacity and power consumption. This is achieved by staggering compressor switch-on sequences that allow the parallel system to match its power with the capacity needed. By switching-off individual compressor from parallel installation, while other compressor is operating 100%, the improved part load effi ciency can be achieved. The specially developed and adopted oil equalization system ensures correct compressors operation, oil balancing between compressors and reliability.

Condensers

Condenser coils are manufactured of seamless copper tubes mechanically bonded to aluminum fi ns to ensure optimum heat transfer.

All coils are tested against leakage by air pressure of 450 psig (3100 kPa) under water. All standard coils are 3 or 4 rows/14 FPI, 3/8” (9.5 mm) O.D. tubes. An integral subcooling circuit is provided to increase the cooling capacity, without additional operating cost.

For different application requirements, other optional condenser fi n materials are available:

Capacity Control Steps

The Standard Capacity Control Steps are shown below.

Table 7

Selection Procedure Example

The following information should be determined:

1. Required total capacity = 445 MBh (130.4 kW)2. Saturated suction temperature = 50°F (10°C) 3. Condenser entering air temperature = 115°F (46°C)4. Power Supply (V/Ph/Hz) = 380/3/505. Refrigerant R407C.

Enter capacity ratings from entering air temperature and select model ACUS 52045 having a cooling capacity of 449 MBh (131.6 kW) at 50°F (10°C) saturated suction temperature, compressor motor power input is 45.2 kW. For further details refer to physical data and specifi cations sheets.

Capacity ratings are based on sea level operation. Above sea level, apply the following corrections method.

Actual capacity (at level) = Sea level capacity x altitude correction factor

Altitude Correction Factors

The unit ratings are based on sea level. Above sea level apply the following correction factors:

SKM Air Cooled Condensing UnitsACUS Series - R22 & R407C

Field ConnectionsACUS series self-contained heavy duty air cooled condensing units are designed for minimum fi eld interaction.

Power hook-ups for AHU starter and fan interlock and control wiring of room unit as per Electrical hook-up diagram is all that is required to electrically connect any model of ACUS series .

Every ACUS series condensing unit requires, at most, fi eld installed fused disconnect switches or circuit breakers, and room unit.

Refer below for a schematic representation of required fi eld electrical hook-ups for a standard ACUS series condensing unit.

All fi eld wiring must be done in accordance with applicable local and national codes.

For maximum recommended fuse sizes and minimum circuit amps for cable sizing, see Page 22~24 of this bulletin.

The ACUS series is then ready to provide cooling, on demand.

Location and Space Requirements

Location and Space RequirementsDue to the vertical air fl ow discharge condenser design, it is recommended that certain precautions are to be taken before installation. There should be no obstruction on the air fl ow.

Orient the unit so that prevailing winds blow parallel to the unit length thus minimizing the effects on condensing pressure. If it is not practical to orient the unit in this manner, a wind defl ecting shield should be considered.

It is also necessary to provide adequate clearance on all sides of the unit for service access and satisfactory performance. This will prevent excessive condensing temperatures and enhance system performance and operating economy.

A fl at concrete foundation or fl oor which can support the weight of the equipment must be provided as the unit must be level for proper operation and functioning of controls.

Under certain critical conditions it is recommended that vibration isolators of rubber-in-shear or spring type be installed under the base.

The isolators must be designed for the operating weight of the unit. For operating load points refer to Loading Points Data (page No.28). Correct selection of types of isolators depends upon application and structure.

Refrigerant Piping

Correct design and size of refrigerant piping is necessary for proper operation. The refrigerant piping generally should be designed to accomplish the following:

a. To ensure proper refrigerant feed to the evaporator.

b. To provide practical refrigerant line sizes without excessive pressure drop.

c. To maintain uniform return of lubricating oil to the compressor.

d. To prevent refrigerant from entering the compressor and causing compressor damage due to "slugging".

Field Expansion Valve Selection

The following recommendations should be taken into consideration when selecting expansion valves in fi eld.

1. Expansion valves should be installed as close to the evaporator as possible, mounted directly to the distributor.

2. The following possible sources of pressure drop to be considered:

a. Friction losses through refrigerant lines.

b. Pressure drop across valves and controls.

c. Pressure drop due to vertical lift of liquid line for R-22 1°F (0.55°C) sub cooling must be allowed for each 5.5 ft (1.7m) vertical rise in order to avoid fl ash gas forming due to the weight of the column of liquid refrigerant.

SKM ACUS Series units are designed with a sub cooling circuit enough to sub cool the liquid 12°F (6.6 °C), which gives the liquid maximum 66 ft. (20m) lift without additional sub cooling. Liquid suction heat exchanger can be used for additional sub cooling in order to avoid fl ash gas forming.

Matching DX Coil Selection

For single circuit ACUS Series, the DX coil selection in a MAH or other air handler from SKM should be based on total capacity. For dual circuit ACUS Series, extra care should be exercised and correspondingly split, by face area or number of rows to correspond and match the capacity split available in the dual circuited ACUS Series selected. For optimum matching the DX coil should be ordered from SKM as well.

SKM provides correct no. of feeds and circuits and properly sized distribution to ensure the correct split on the DX coil is made available to match the particular selected ACUS Series model.

SKM Air Cooled Condensing UnitsACUS Series - R22 & R407C

Recommended Refrigerant Line Sizes - 50 Hz

SKM ACUS Series Condensing Units are designed for satisfactory operation with single suction line.1. Suction Line sizing selection recommendation in 2. Double suction risers, for applications with systems having large variations in capacity , are recommended to ensure proper

oil fl ow up and return to compressor.

4. Recommended line sizes in references like ASHRAE Guide and Data Book for assistance.
