摘要：In allusion to a systematic test for the ordinary bathing system: the temperature of outflow is about 40°C, but the waste water has an average temperature of about 36°C, so we can know the use rate is just 16.7%, and the rest heat is let out. There is research finds that ORC is the best way to promote the use rate. Look into the case from the first law of thermodynamics. If we use one type or two types of pure refrigerants such as R123, R600a, R600 and mix at free percentage, the products are the fittest for the temperatures from 30°C to 100°C in the bathroom. Under the circumstances in nowadays bathroom, the multi-level energy exploitation system based on ORC can promote the heat use rate from waste water to 25%, and the mixed refrigerants have superiorities in the heat utilization of ORC system.
