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 condenser and evaporator are brazed plate heat exchanger and utilize a large common reservoir of water to minimize changes in water temperature during operation. 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.
Anodized aluminum structure and panels of painted steel.
The unit includes wheels to facilitate its mobility.
Experimental unit for the training of apprentices for refrigeration area that allows the investigation of a refrigeration system with different expansion elements.
