The invention discloses an ice heat storage air conditioning unit and a control method thereof, belongs to the technical field of air conditioning units and control methods thereof, and is designed for solving such problems as limited stored energy of an existing device. The ice heat storage air conditioning unit comprises an energy storage air cooling heat pump type device and an energy storage tank connected with each other; the energy storage air cooling heat pump type device includes a compressor component, an air side heat exchanger and a water side heat exchanger connected in sequence through a pipeline; the energy storage tank includes an air conditioner refrigerant channel and a user side refrigerant channel; a port of the air conditioner refrigerant channel is connected to the energy storage air cooling heat pump type device; and a port of the user side refrigerant channel is connected to a user side. The double-medium energy storage tank of the ice heat storage air conditioning unit increases the energy storage capacity, so that the energy storage advantage can be fully exerted, and the operation cost can be reduced; and the ice heat storage air conditioning unit can achieve high refrigeration coefficients without a brine pump. The control method of the ice heat storage air conditioning unit can realize multiple functions according to the load condition of the user side.
Description
technical field [0001] The invention relates to the technical field of an air-conditioning unit and a control method thereof, in particular to an ice-storage air-conditioning unit and a control method based on the ice-storage air-conditioning unit. Background technique [0002] Ice heat storage technology can play a role in peak load shifting and valley filling. While alleviating power shortage, it can improve the operating efficiency of power company equipment under low power load at night, and can also reduce the installed capacity of heat pumps. [0003] Existing air-conditioning units are equipped with accumulators using a single medium (such as refrigerant), the amount of energy storage is very limited, and the advantages of energy storage cannot be fully utilized; Realize the function of releasing cold and heat directly to the user, the application range is limited, the floor area is large, and the cost is high.
