Problems solved by technology

However, the air-conditioning system using the ice storage unit and its control method have the following disadvantages: the heating mode is turned on at the same time during the actual heat storage operation, and heat storage cannot be carried out in the heating gap of the unit, and can only store the heat for indoor heating. Insufficient heat storage capacity within a certain period of time; running the heat release mode in a low temperature environment will cause the disadvantages of the stored heat being lost to the environment through the outdoor heat exchanger; the stored heat can only be used for air conditioning heating, and cannot meet both heating and cooling The purpose of producing domestic hot water at the same time

Abstract

The invention discloses a multifunctional ice storage air conditioning hot water system capable of efficiently utilizing peak and valley price. The air conditioning hot water system can greatly enhance the running efficiency of an air conditioning system and the utilization efficiency of energy by additionally arranging a heat exchanger among an ice storage cylinder, an outdoor heat exchanger andan indoor heat exchanger and arranging an electromagnetic valve which can be independently controlled at both ends of the ice storage cylinder and both ends of the outdoor heat exchanger. In addition, the invention also discloses a control method for the air conditioning system.

Description

technical field [0001] The invention relates to the fields of refrigeration and air conditioning, heat pumps and heat pump water heaters, in particular to a multifunctional ice-storage air conditioning system capable of effectively utilizing peak and valley electricity prices and a control method for the system. Background technique [0002] Ice storage air conditioning technology is an energy-saving technology that uses cheap valley electricity to make ice and store energy and release cold energy for air conditioning during peak electricity. Ice storage air conditioners can be roughly divided into two categories: static ice making and dynamic ice making. Among them, there are two kinds of ice melting methods for static ice making, one is the external ice melting method, and the other is the internal ice melting method. Small ice storage air conditioning units generally use direct fluorine refrigeration for ice storage and internal ice melting. The cold energy released by m...
