Abstract

The invention discloses a heat source tower heat pump system based on soil energy storage. The heat source tower heat pump system based on soil energy storage comprises a refrigerant loop, a solution loop, a soil energy storage loop and a cold and hot water loop, wherein the refrigerant loop is composed of a first refrigerant loop and a second refrigerant loop. The heat source tower heat pump system based on soil energy storage realizes cross-seasonal energy storage in winter and summer by utilizing soil, solves the problems of a heat source tower heat pump of overlarge unit installed capacity and difficulty in improvement of efficiency caused by considering extreme weather in the winter and the summer, reduces the installed capacity the initial cost of the heat source tower heat pump, also realizes undercooling of a refrigerant of a heat source tower heat pump unit in the summer and regeneration of the solution of the heat source tower heat pump unit in the winter by utilizing heat of the soil, greatly improves the refrigerating and heating efficiencies of the heat source tower heat pump system, also efficiently and economically solves a heat source for regeneration of the solution of the heat source tower heat pump in the winter and realizes comprehensive and efficient running of the system for the whole year.

Description

technical field [0001] The invention belongs to the field of refrigeration and air-conditioning system design and manufacture, and relates to a heat source tower heat pump system that uses soil to realize energy storage across seasons. Background technique [0002] The heat source tower heat pump system is a new type of building cold and heat source scheme. It can realize the high efficiency of water-cooled chillers in summer, and at the same time, it can use the solution to exchange heat with the air in the heat source tower in winter, and absorb the heat in the air as the low-level heat source of the heat pump. In order to realize heating, it is applied in hot summer and cold winter regions. Compared with the traditional building cold and heat source solutions, the heat source tower heat pump: air source heat pump, chiller + boiler and water / ground source heat pump, there is no frosting problem of air source heat pump in winter and has higher efficiency in summer; the ch...
