摘要
提出采用相变蓄热器(作为除霜工况时的主要低温热源)提高空气源热泵除霜能力。在中度、重度结霜工况下,对室外机换热器表面温度、相变材料温度、压缩机吸排气压力、室内机换热器表面温度随除霜时间的变化进行实验研究,以此评价采用相变蓄热器后空气源热泵的除霜能力。
The phase-change heat storage device is used as principal low-temperature heat source during defrosting to improve the defrosting capacity of air-source heat pump. Under the moderate/severe frosting conditions, the variations in surface temperature of heat exchanger for outdoor machine, phasechange material temperature, compressor suction and discharge pressure and surface temperature of heat exchanger for indoor machine with defrosting time are experimentally studied to evaluate the defrosting capacity of air-source heat pump using phase-change heat storage device.
