Description of  Vapour Compression Refrigeration Unit

The hermetically sealed refrigerant compressor incorporates a brushless three phase DC electric motor that is driven by a variable speed controller. Compressor speed and power supplied is displayed on the PC.

The refrigerant exiting the compressor passes through a condenser, receiver, filter, variable area flow meter, expansion valve and evaporator before retuning to the inlet side of the compressor. The condenser and evaporator are brazed plate heat exchanger and utilize a large common reservoir of water to minimize changes in water temperature during operation.
