FEATURES Optimum Designs for Individual Requirements

Cooling Units

High Performance Evaporator Fan The powerful and efficient multi-blade centrifugal fan creates high static pressure with minimum power consumption and smooth air flow. Evaporator fan bearings can be replaced without removing fans. An adjustable motor pulley is mounted in RAS-6U2S through RAS-20U2S, in order to cover wider ranges of fan speed.

Well-Designed Evaporator Highly-Efficient cross fin coils have been applied to provide a larger cooling capacity with low air speed on the coil.

Condensing Units

Energy-Saving Design Highly-Efficient Scroll Compressors - Low power input is achieved by specially designed compressors and heat exchangers and their combinations.

Optional Accessories Filter Box and Filter - A high performance air filter and a filter box are provided for the return air connection of all models.

SELECTION DATA

Selection GuideSelection Example:

1. Determine the System Requirements

Calculate the total cooling capacity, sensible heat capacity, evaporator air flow and required external static pressure according to the design conditions. Clarify the power source frequency and the climatic conditions.

Given Conditions: Total Cooling Capacity 27,500 kcal/h Sensible Heat Capacity 21,000 kcal/h Condenser Air Inlet Temperature 40°C Evaporator Air Inlet Dry Bulb 29°C Evaporator Air Inlet Wet Bulb 20°C Evaporator Air Flow 115 m3/min External Static Pressure 16 mmAq Power Source 415V / 50 Hz Climatic Conditions High / Medium

2. Select a Matching Model Select model RAS-13U2S+RAS-13CT2S, by entering 40°C condenser air inlet temperature and 20 °C evaporator air inlet wet bulb (WB) at 110 m3/min. Evaporator air flow (QA) in the Cooling Capacity Table.(RAS-13U2S+RAS-13CT2S unit will provide cooling capacity of 29,200 kcal/h and a sensible heat capacity of 21,700 kcal/h)

3. Read Performance of the Model

The total cooling capacity (TC), sensible heat capacity (SHC*) at the dry bulb given in the table, compressor power input (IPT), and sensible heat correction factor (CR) can be determined by interpolation (or some can be read directly from the table when the conditions coincide with the tabulated figures).

At 20℃ WB

TC SHC* IPT CR (x1,000 (x1,000 kcal/h) kcal/h) (kW)

At 121 m3/min QA 30.2 22.8 11.0 1.82

At 110 m3/min QA 29.2 21.7 10.9 1.69

At 115 m3/min QA 29.7 22.2 11.0 1.75

(By Interpolation)

4. Correct the Sensible Heat Capacity (If Required)

Correct the sensible heat capacity for the given 29°C evaporator air inlet dry bulb from the tabulated 27°C (DB*) according to the following formula.

SHC =SHC*+CR×(DB-DB*), where,

SHC : corrected sensible heat capacity (×1,000kcal/h),

SHC* : sensible heat capacity from in the table (×1,000kcal/h),

DB : given evaporator air inlet dry bulb (°C) and

DB*: evaporator air inlet dry bulb (°C) given for each WB in the table.

For this example,

SHC =22.2+1.75x(29-27)=25.7(x1,000kca/h) 5. Determine the Readjusting Requirements for

Evaporator Fan From the Fan Performance Table (Page 19), the required fan speeds and motor brake power are determined to be 1,045 rpm and 1.10kW, respectively. (Evaporator fan motor input is 1.19kW as seen on Page 23, Electrical Data-Cooling Unit-IPT column for evaporator fan motor at 415V). In this case, the factory-mounted standard fan motor (2.2kW) possesses sufficient capacity. However, the regulation space of the adjustable motor pulley should be readjusted to 2.2mm (see “Fan Speed Adjustment” on Page 21).

6. Determine the Net Capacity

The capacities are gross capacities, which include the effect of evaporator fan motor heat. To determine net capacity as follows: Net capacity =gross capacity – MIF heat

=gross capacity (kcal/h) – MIF input (kW) x 860 (kcal/kW.h)

=30,100 kcal/h – 1.19 kW x 860 kcal/kW.h =30,100 kcal/h – 1,023 kcal/h =29,077 kcal/h

Net sensible capacity =25,700 kcal/h – 1,023 kcal/h =24,677 kcal/h

NOTE: 1.Direct interpolation is permissible. Do not extrapolate.

CONTROL SYSTEM Refrigerant Control

Refrigeration Cycle

Condensing Unit Models RAS-13CT2S through RAS-20CT2S are composed of two refrigeration cycles. In addition to the basic condensing unit components (compressor and air-cooled condenser), the following components are equipped in each circuit.

Stop Valves for Gas Line and Liquid Line – These stop valves are equipped at the unit piping connections, and enhance the evacuation and charging functions.

Cooling Unit Refrigerant Flow Control – Thermal expansion valves are equipped for models RAS-13U2S, RAS-15U2S and RAS-20U2S.

Dryer – A filter-dryer is shipped for installation at the site. (for models RAS-13U2S, RAS-15U2S and RAS-20U2S)

Electrical Operation Control

A field-supplied main power switch supplies to the unit. When the room thermostat is set at “FAN ON” position, the indoor fan is started. When the room thermostat is set at “FAN AUTO” and “COOL ON” position, all electrical and protective devices are satisfied, the thermostat in the room thermostat controls the compressor operation (refer to “Operational Sequence Chart”).

Capacity Control – The field supplied Room Thermostat for the dual-circuited models starts and stops compressor operation in each circuit, responding to the room temperature with the room thermostat elements. This system enables full load, 60% or 50% load and no load (ceasing both compressor) operations. Function of Safety Devices Automatic Restarting System (Standard Sequence) – The timer relay for compressor connected in the compressor control circuit delays the compressor restarting period for approximately three (3) minutes after the thermostat calls for the cooling operation or automatic resetting of the protection devices, thereby preventing a harmful compressor cycling operation.

CONTROL SYSTEM

Protection and Safety ControlCompressor Protection All units are equipped with the following compressor protection system, in order to provide a perfect guarding function for the compressor.

High Pressure Switches – Leading the pressures from the compressor discharge lines, this switch cut out the compressor operation when the discharge pressure exceeds the setting pressure.

Overcurrent Transformer – This sensor stop the compressor operation when the current exceeds the setting.

Internal Thermostat for compressor – Embedded in the compressor motor winding, this thermostat cuts out the compressor operation when the compressor winding temperature exceeds the setting.

Reverse Phase Protection – The reverse phase protection which is a built-in function of PCB will make the compressor not start when the power source is incorrectly connected.

Compressor Cycling Protection Timer – This timer which is a built-in function of PCB provides the above combination with the most effective functions by delaying the compressor restarting period (refer to “Operational Sequence Chart”)

Other Protection

The fan motor is protected by the following device:

Overcurrent Relay for Evaporator Fan Motor – This manual reset type thermal overcurrent relay for the evaporator fan motor interlocks system operation.

Internal Thermostat for Condenser Fan Motor – Embedded in the fan motor winding, this internal thermostat cuts out the operation of the fan motor when winding temperature exceeds the setting.

Internal Thermostat for Evaporator Fan Motor – Embedded in the fan motor winding, this internal thermostat cuts out the operation of the fan motor when winding temperature exceeds the setting. (RAS-4U2S and RAS-5U2S only)
