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...
