Abstract

The invention provides a heat recovery system for an air conditioning unit. The heat recovery system is characterized in that an air outlet of a compressor, a heat recovery device, a condenser, an evaporator and an admission port of the compressor are sequentially connected through pipelines to form a refrigerant loop, a heat recovery bypass is provided with a first flow control device, the heat recovery device is used for recovering heat carried by a refrigerant and realizing heat exchange between the refrigerant and water, a temperature sensor (a temperature detection device) is arranged on the heat recovery device, and the first flow control device can adjust the flow rate of a fluid flowing through the first flow control device according to temperature detected by the temperature sensor (the temperature detection device). According to the heat recovery system for the air conditioning unit, heat of the high-temperature and high-pressure refrigerant produced by compression of the compressor is recovered by the heat recovery device to be used for hot water preparation, and the heat recovery bypass connected in parallel with the heat recovery device can distribute the high-temperature and high-pressure refrigerant according to the temperature of prepared hot water, so that the temperature of the hot water prepared by use of the recovered heat is more stable.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a heat recovery system of an air-conditioning unit and a control method thereof. Background technique [0002] During the refrigeration process of the air conditioning unit, the condensation heat in it is recovered and utilized, such as preparing hot water for users. Traditionally, the high-temperature and high-pressure refrigerant of the air-conditioning unit exchanges heat with water in the heat recovery device, and generates hot water in the heat recovery device for users to use. However, the temperature of the hot water generated in the heat recovery device is often too high or the temperature is not good. Stable and affect the normal use of users. Contents of the invention [0003] Based on this, it is necessary to provide a heat recovery system for an air conditioner unit and a control method thereof for the problem that the temperature of hot water ge...
