摘　　要：为回收家庭洗浴废水中的废热,提高能源利用率,本文设计了一种带废热回收的热泵热水装置,并通过搭建实验台研究了该装置制取热水的循环性能。在进水温度为16℃,出水温度为36~46℃时进行实验测试,研究制热量、制热COP、压缩机功率、出水量等参数随出水温度和制冷剂充注量的变化规律。实验结果表明:适当提高制冷剂充注量有利于制热量、制热COP的稳定,在最小的制冷剂充注量为1.4 kg时,获得最大制热量为7.9 k W,制热COP为7.7;在出水温度为36~46℃,随出水温度的升高,压缩机功率增大,出水体积流量下降。该装置能够有效回收废水中的热量,制热量稳定在约7.5 k W,制热COP大于6.0。To recover waste heat from household bath wastewater and improve energy efficiency,a heat pump water heater with waste heat recovery was designed. Experimental benches were set up for experimental studies. The experiment was carried out with an inlet water temperature of 16 ℃ and an outlet water temperature of 36-46 ℃ to study the variation of parameters such as the heating capacity,heating coefficient of performance( COP),compressor power and volume flow of water outlet with the water outlet temperature and refrigerant charge. The experimental results show that increase refrigerant charge appropriately is beneficial to the heating and heating COP stability.The maximum heating capacity is 7.9 k W,and the heating COP is 7.7 at the minimum refrigerant charge 1.4 kg. The compressor power increases and the volume flow of water decreases with outlet water temperature from 36 ℃ to 46 ℃. The device can effectively recover the heat from the waste water,and obtain the stable heating at approximately 7.5 k W and the heating COP above 6.0.
