Refcomp SRC-S(W)-985 SRC-S-985-L4 R404A Screw Air Conditioning Compressor for Refrigeration

Q1: How can I determine the required cooling capacity for my HVAC system?

For screw air conditioning compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The SRC-S(W)-985 has a displacement of 1100 m³/h at 50 Hz and 1320 m³/h at 60 Hz, but actual cooling capacity must be verified against manufacturer performance data.

Q2: What should be considered when replacing an existing air conditioning screw compressor?

Compare the suction and discharge connections, mounting dimensions and electrical requirements with the existing installation. Check the available lifting access and supporting structure, as the SRC-S(W)-985 weighs 1400 kg.

Q3: How should capacity control be configured for changing cooling loads?

The SRC-S series specifies 100%, 75%, 50% and 25% capacity stages, with stepless regulation from 100% to 25%. Confirm the supplied control configuration and ensure the HVAC controller supports the required capacity adjustment method.

Q4: What should I check if the motor protection module trips during operation?

Inspect the power supply, phase sequence, motor temperature, PTC sensor connections and refrigeration operating pressures. Identify and correct the underlying fault before resetting the protection module or restarting the compressor.
