Water Water Heat Pump Apparatus

Product Description

Description of DIDAC Water Water Heat Pump ApparatusThe 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.Experimental Capabilities of Water Water Heat Pump Apparatus Determination of power input, heat output and coefficient of performance. Production of heat pump performance curves over a range of source and delivery temperatures. Plotting the vapour compression cycle on a p-h diagram and comparing this with the ideal cycle. Determination of energy balances for condenser and compressor. Production of heat pump performance curves based on properties, at a variety of evaporating and condensing temperatures. Estimation of the effects of compressor pressure ratio on volumetric efficiency.
