Problems solved by technology

Air source heat pumps are less efficient in cooling in summer, and have frosting problems in heating in winter; when the chiller + boiler scheme is used for heating in winter, the chiller is idle, and the boiler is used to burn oil or natural gas for heating, which has low primary energy utilization efficiency. High-level deficiencies; the ground source heat pump scheme has special requirements for geographical and geological conditions, and its use and promotion are restricted

Abstract

The invention discloses an integrated heat source tower heat pump device based on comprehensive utilization. The integrated heat source tower heat pump device based on the comprehensive utilization comprises a refrigerating agent loop, a solution loop and an air loop. Through control over a first electric three-way control valve, the ratio of solution, coming out from a finned tube exchanger, of a first solution pump to solution absorbed from a heat source tower is adjusted, so that control over the temperature of solution entering the finned tube exchanger is achieved. Therefore, adjustment of the dehumidification amount of air in the finned tube exchanger is achieved. According to the integrated heat source tower heat pump device based on the comprehensive utilization, heat released by super-cold refrigerating agent or overheated refrigerating agent is used for regenerating solution, and based on air closed circulation, high-efficiency regeneration of the solution of a heat source tower heat pump system is achieved, the problem of regeneration of the solution of the heat source tower heat pump system is thoroughly solved, safe reliability of the heat source tower heat pump system under various operation conditions is improved, and comprehension and high efficiency of the system are achieved.

Description

[0001] Technical field [0002] The invention is the design and manufacturing field of refrigeration and air -conditioning systems, involving a device that realizes the thermal pump thermal pump thermal pump thermal pump thermal pump thermal pump thermal pump thermal pump thermal pump thermal pump heat -making. [0003] Background technique [0004] The air -conditioning heat and heat source scheme adopted by the building includes the air source heat pump scheme, the cold water unit+boiler solution, and the ground source heat pump scheme.The air source heat pump is relatively efficient during summer refrigeration, and there is a frosting problem during winter heating; the cold water unit+boiler solution is heated in winter, the cold water units are idle, and the boiler combustion oil or natural gas heating is used.Higher deficiency; the geographical heat pump scheme has special requirements for geological and geological conditions, and the use of promotion is restricted.The new t...
