本文介绍了一种除湿与热泵热水耦合的系统,并在标准焓差实验室分别对该系统的热泵供热水、除湿和热泵供热水+除湿3种模式进行了实验,总结了各种模式下各参数随时间的变化趋势。实验结果表明:热泵供热水模式下系统的COP达到了《家用和类似用途热泵热水器》(GB/T 23137-2008)中要求的3.7;除湿模式下系统的除湿量和单位功耗除湿量分别达到了1.35 kg/h和1.8 kg/(h.kW),比《除湿机》(GB/T 19411-2003)中的要求分别高出了12.5%和18.4%;热泵供热水+除湿模式下系统的综合性能得到了整体改善,较之单独的热泵供热水模式,系统的综合COP提升了3.78%,但除湿量较除湿模式下降低了11.85%,单位功耗除湿量降低了11.1%。
In this paper, a system of dehumidification and heat pump hot water coupling is introduced. Three models of heat pump hot water supply, dehumidification and heat pump hot water supply + dehumidification are respectively tested in the laboratory of standard enthalpy difference. Mode of the parameters with the trend of change over time. The experimental results show that the COP of the system in the heat pump water heating system meets the requirement of 3.7 in the “Household and similar heat pump water heater” (GB / T 23137-2008); the dehumidification capacity and the unit power consumption dehumidification capacity in the dehumidification mode are respectively Reached 1.35 kg / h and 1.8 kg / (h.kW), respectively, 12.5% and 18.4% higher than the requirements of “dehumidifier” (GB / T 19411-2003) respectively; heat pump hot water + dehumidification mode Overall system performance has been overall improved, compared with a single heat pump water heating mode, the system’s overall COP increased by 3.78%, but dehumidification reduced by 11.85% than the dehumidification mode, unit power dehumidification decreased by 11.1%.
