FEATURES

EFFICIENT, RELIABLE AND DURABLE NEW SERIES‧‧‧★ Baked Paint Galvanized Steel Panels Corrosion Resistant Cabinet ─ The weather proof characteristics of the panels have been significantly reinforced by the adoption of galvanized steel panel which have been coated with synthetic resin paint through our unique baking process. The resistant panels ensure long-lasting fine appearance, and maintenance work has been minimized. ★ Reliable Protection System Compressor Protection ─ Each compressor is protected with the following components: reverse phase protection, overcurrent protector, internal thermostat, high pressure switch, delay timer. This wide variety of protection devices provides perfect compressor guarding functions, assuring fewer service calls from customers. Fan Motor ─ The evaporator fan motors are protected with thermal overcurrent relay, internal thermostat (RUA-4AT3S, RUA-5AT3S only) and the condenser fan motors are protected with an internal thermostat.

★ Energy-Saving Design Highly-Efficient Compressor ─ Low power input is achieved by specially developed compressors and heat exchanger and their suitable combinations. Condenser ─ The adoption of a highly efficient super-slit fin heat exchanger provides low operation cost.

Evaporator ─ Highly efficient super-slit fin coils and inner grooved tube have been applied, to provide a large cooling capacity with low noise. Insulated Indoor Compartment ─ This insulation compartment effectively eliminates heat loss. Capacity Control (Dual circuit units) ─ Each unit is equipped with two or three compressors and two independent refrigeration cycles so that one compressor operation can reduce the operation cost against a half load of one large compressor (60% load operation is available for RUA-13AT3S and RUA-15AT3S, 66% load operation is available for RUA-30AT3S)

EFFECTIVELY MATCHED SELECTION FOR INDIVIDUAL APPLICATIONS‧‧‧ ★ Optimum Matched Choice High Temperature Operation ─ Designed for high outdoor temperatures, these units guarantee reliable operation even under condition up to an ambient temperature of 52°C(125°F). Attractive Fan Performance ─ Adequate external static pressure by the evaporator fan can be obtained for individual ducting applications. ★ Minimum Installation Arrangement

Easy Installation ─ This easy-to-install and ready-to- operate unit ensure rapid and low cost installation work. Pre-Drilled Duct Flange ─ Flanges are prepared at the supply and return duct connections so that they can reduce duct connection work at the site.

Factory-Completed ─ Only system connection work is required, excluding the installation work for auxiliary equipment.

★ Quiet Operation

Compressor ─ Noise and vibration have been effectively reduced by the adoption of new hermetic compressor. Condenser Fan ─ This direct driven propeller fan is dynamically balanced to ensure smooth airflow. Evaporator Fan ─ The centrifugal fan and fan casing are optimum shaped for efficient and low noise operation. ★ Reduced Maintenance Work

Easy Maintenance ─ Large service spaces and rapidly removable service panels have been provided for easy maintenance work.

SELECTION DATA

Selection GuideSelection Example

1. Determine the System Requirements Calculate the total cooling capacity, sensible heat capacity, evaporator airflow and required external static pressure according to the design conditions. Clarify the power source frequency and the climatic conditions

Given Conditions： Total Cooling Capacity 35,500kcal/h Sensible Heat Capacity 26,500kcal/h Condenser Air Inlet Temperature 40°C Evaporator Air Inlet Dry Bulb 29°C Evaporator Air Inlet Wet Bulb 20°C Evaporator Air Flow 135m3/min. External Static Pressure 15mmAq Power Source 415V 50Hz

2. Select a Matching Model Select model RUA-15AT3S, by entering 40°C condenser air inlet temperature and 20°C evaporator air inlet wet bulb (WB) at 130m3/min. evaporator air flow (QA) into the Cooling Capacity Table. (RUA-15AT3S Unit will provide cooling capacity of 37,700 kcal/h and sensible heat capacity of 26,800 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°C WB Tc

At 135m3/min.QA 38.2 27.3 14.0 2.06 (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 dry bulb (DB*), according to the following formula.

SHC = SHC* + CR × (DB – DB*), Where SHC = corrected sensible heat capacity

(×1,000kcal/h ) SHC* = sensible heat capacity (×1,000kcal/h)

from the table. DB* = given evaporator air inlet dry bulb (°C)

and WB in the table. DB = evaporator air inlet dry bulb (°C)

given for each. For this example, SHC = 27.3 + 2.06×(29-27) = 31.4 (×1,000kcal/h)

5. Determine the Readjusting Requirement for Evaporator Fan From the Fan Performance Table (page 17) the required fan speeds and evaporator fan motor brake power are determined to be 1,080 rpm and 1.23 kW respectively. (Evaporator fan motor input is 1.7 kW as seen on page 23 Electrical data IPT column for evaporator fan motor at 415V). In this case, the factory-mounted standard fan motor (2.2 BkW) possesses sufficient capacity. However, the regulating thickness of the adjustable motor pulley should be readjusted to 2 mm (refer to “Fan Speed Adjusted” on page 21).

6. Determine the net capacities The capacities are gross capacities, which include the effect of evaporator fan motor heat. Determine the net cooling capacity as follows: net capacity = gross capacity – MIF heat = gross capacity – 1.7 (kW) X 860 (×kcal/kW-h) = 38,800 kcal/h – 1,462 kcal/h = 37,338 kcal/h net sensible capacity = 31,400 kcal/h – 1,462 kcal/h = 29,938 kcal/h

NOTE: Direct interpolation is permissible. Do not extrapolate.

CONTROL SYSTEM Refrigerant Control

Refrigeration Cycle These models are composed of one or two refrigeration cycles, containing a compressor, a condenser, an evaporator and the following control and auxiliary components. Capillary Tube ─ Multi-tube type capillaries are equipped for refrigerant flow control in the liquid line, providing equal distribution of refrigerant flow through the evaporator.

Strainer ─ A liquid line strainer is equipped upstream of the capillary tube.

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”).

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.

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 Switch ─ Leading the pressure from the compressor discharge line the switch cuts out the compressor operation when the discharge pressure exceeds the setting.

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 interlock 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.
