| Abstract: | Performance of heat pump water heater with heat charging,preheating and discharging system was analyzed by experimental apparatus.The performance of phase-changing material and R-22,and the power compressor were also analysed. This kind of heat pump water heater utilizes the partition to heat up and the highly effective adverse current heat transfer technology,which results in the cost structure of heat pump water heater should be reduced.The usage of preheating made the condensation pressure reduced.The co... |
