Water heating system of multifunctional ice accumulation air conditioner and its control method

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 and an 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 air conditioners, heat pumps, and heat pump water heaters, in particular to a multifunctional ice storage air conditioner hot water system that can effectively utilize 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 off-peak electricity to store ice 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 according to the ice-making method. Among them, there are two methods of ice melting in static ice making, one is external ice melting, and the other is internal ice melting. Small ice-storage air-conditioning units generally use direct fluorine refrigeration to store ice and melt ice internally. The cold energy released by melting ice...

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
