【Abstract】 In view of the shortcomings of the current ammonia water absorption heat pump cycle, this paper proposes a new ammonia water absorption heat pump cycle. By increasing the circulation of refrigerant solution, the condensation pressure is reduced to below 2 MPa, and by spraying part of the evaporator to the generator to evaporate the tail liquid, the refrigerant solution circulation refrigerant balance is achieved, and the distillation process is simplified; For ground source heat pump and air source heat pump working conditions, the new ammonia absorption heat pump can achieve heat supply above 75 ℃, meet the long-distance heat supply requirements of large and medium-sized heating stations, and its thermal performance is 1.28～1.48; This paper demonstrates the engineering feasibility of the new ammonia water absorption heat pump unit from the structure, material and control regulation of the main components, and expounds the solution of the new ammonia water absorption heat pump unit in view of some difficulties faced by the current heating.更多还原
