Description of DIDAC Water Water Heat Pump Apparatus
The components of the Water Water Heat Pump and its instrumentation are mounted on a gloss finish high quality plastic panel.
The Water Water Heat Pump consists of a hermetic compressor, an efficient plate heat exchanger condenser and evaporator, a liquid receiver, a thermostatically controlled expansion valve.
The components are clearly but compactly arranged in a manner similar to that used for many domestic air-water heat pumps and all are visible from the front of the unit.
The operating cycle is as follows:
Slightly superheated Refrigerant vapour enters the compressor from the evaporator and Water Water Heat Pump pressure is increased. This brings about a rise in temperature and the hot vapour enters the water cooled plate condenser. Heat is given up to the cooling water and the refrigerant condenses to a liquid before passing to the liquid receiver and then the expansion valve.
