Abstract:To addressthe high energy consumption issue in the regeneration of antifreeze for heat source tower heat pump,a low-temperature vacum solution regeneration system based on heat pump was designed and constructed,and experimental researchon itsregenerationcharacteristicswas carred out.Theresults show that the optimal evaporation temperature and condensation temperature of the heat pump are 30°C and 55∘C (204号 respectively under the design conditions.During the regeneration proces,the water production rate of the system increased by2 percentage points when the solution filling amount increased from 20kg to 80kg .When the solution concentration increased from 10% to 30% ,the water production rate of the system decreased by 1.2 percentage points.When the vacuum degree increases from 84% to 93% ,the water production rate of the system increases by 47.3 percentage points.The system can operate continuously and stably,with daily water production of 1.4t and unit energy consumption evaporation of 6.33kg/(kW⋅h) . The research conclusion can provide reference for low energy consumption and high efficiency regeneration of solutions.

Keywords:antifreeze solution; low temperature vacuum regeneration; heat pump; solution regeneration; regenerationcharacteristic
