Research on Compound Condensation/Evaporation of Four Functional Heat Pump Performance
Compound condensing heat pump combines the advantages of heat pump technology and condensing heat recovery technology. It takes full account of the common infrastructure in the cooling and heat source system and greatly increases equipment utilization ratio. It also recycles condensing heat to produce sanitary hot water efficiently while ensuring cooling and heating of heat pump to achieve the same effect. The distinctive technical features of the compound condensation / evaporation of four functional heat pump ensure its efficient and reliable operation. This heat pump system runs in several models throughout the year,which include the refrigeration mode, refrigeration&domestic hot water mode, domestic hot water mode and heating mode. The performance in refrigeration mode and refrigeration&domestic hot water mode is studied by a designed experiment is done and the an explicit analysis is made. By comparing the results of simlation and experiment,an agreement can be shown clearly. Therefore,the final conclusion is drawn:the performance of compound condensation / evaporation of four functional heat pump is improved over the traditional heat pump.It is worthy to further promote for the sake of energy saving.
