Reciprocating Compressors TWB1390YKS

Product catalog summary

Product Description
Model TWB1390YKS is a reciprocating compressor designed for low back pressure (LBP) applications using R134a refrigerant. It operates at a voltage/frequency of 220-240V ~ 50Hz.

Product Specifications
Performance: The compressor's refrigeration capacity and efficiency are tested under ASHRAE and CECOMAF conditions. At 220V ~ 50Hz, the ASHRAE test shows a capacity of 815 Btu/h with an input power of 239 W, resulting in an efficiency of 4.88 Btu/Wh. The CECOMAF test shows a capacity of 600 Btu/h with an input power of 176 W, resulting in an efficiency of 3.8 Btu/Wh.
General: The evaporating temperature range is from -34.4°C to -12.2°C. The motor has a low start torque, and the compressor cooling is static.
Mechanical: The compressor weighs 9.939 kg and has a displacement of 8.36 cc.
Electrical: The voltage range is 198-264V for 50 Hz. The locked rotor amps (LRA) is 12.5, and the rated load amps (RLA) is 1.19 for 50 Hz. The overload type is external, and it uses a PTC relay.
Agency Approval: The model is CE, GOST RUSSIA, IMQ, and IRAM listed.

Performance Data
The performance data sheet provides detailed information on the compressor's performance at various evaporating and condensing temperatures. For example, at an evaporating temperature of -40°C and a condensing temperature of 30°C, the capacity is 323 Btu/h with a power consumption of 78.4 W and a current of 0.74 amps. The data includes coefficients for capacity, power, current, and mass flow, which are used in a polynomial equation to calculate performance values based on evaporator and condensing temperatures.
