Abstract Based on the characteristics of sewage from beauty salons, a simulation model of a small sewage source heat pump
triple supply system that can be applied to such places is established to optimize the operating conditions of the
system. The results show that with the increase of sewage temperature and flow, the performance of the system
also increases. In summer conditions, the system provides cooling, recovers waste heat and condensed heat from
sewage, with a COP value of 8.97; in winter conditions, the system heats and produces hot water, with a COP
value of 2.44; in transitional seasons, only hot… More >
