Compressors and condensing units tests

Compressors and condensing units tests

A compressor condensing unit is a device designed to compress and condense a refrigerant.
 
  • Cooling capacity
  • Driving power
  • Safety testing
  • PN-EN 13771 standard

The Central Refrigeration Center has stands designed for energy testing of compressors and condensing units with displacement capacities from 5 to 30 m3/h and safety testing of these devices.

 

It consists of: a compressor unit, i.e. a compressor fully equipped with control, regulation and safety devices, shut-off fittings, oil separator (in the case of piston and rotary compressors), a coupling or belt transmission, drive motor, auxiliary equipment and: condenser, tank liquid refrigerant, liquid refrigerant drier (in the case of freon devices), regenerative heat exchanger (option).

All these elements are mounted on a common frame or supporting structure, and the connectors for external connections are properly prepared and blinded.

Design solutions of the units depend primarily on the cooling capacity and the method of cooling the condenser. Due to the method of cooling the condenser, condensing units are divided into:

  • condensing units with a water-cooled condenser,
  • condensing units with air-cooled condenser.

Condensers in units with a cooling capacity of Q 0 3.5 kW are usually air-cooled, as a rule, forced cooling air flow is used, and the air movement is caused by the operation of the fan.

Condensers with a gravity flow of cooling air are used in low-power refrigeration equipment.

Condensing units cooperate, among others. with refrigerated furniture (showcases, wardrobes, shop counters, etc.), are used to cool cold rooms, ice machines, ice cream machines, air conditioners. The correct operation of the unit depends on the correct selection of its components and proper assembly. These devices are subject to very high technical requirements, such as high cooling capacity with low energy consumption and a high level of operational safety.

The Central Refrigeration Center has stands designed for energy testing of compressors and condensing units with displacement capacities from 5 to 30 m3/h and safety testing of these devices.
