Mobile solar assisted heat pump with direct expansion
This paper presents development of direct- expansion solar assisted heat pump system (DX- SAHP) along with the results of the trial testing. The main purpose of the developed unit with 300 l water tank is to heat up the water by 45 to 55°C. The unit is designed as a test rig enabling all necessary measurements to evaluate potential of solar irradiation for domestic water heating on various locations. A mobile and compact-in-form- and-size device has been developed representing a gradual step towards the commercial application. First set of measurements has been carried out explaining procedures in examination of the working parameters. The evaporation dynamics of the refrigerant in the collector/evaporator has been examined by means of quantitative infra- red thermography method. Computational fluid dynamics simulation has been carried out providing temperature distribution in the water tank. It was compared with the results obtained by temperature measurements by means of thermocouples that were placed in the water tank.
