Multi-split air conditioner heat recovery system and multi-split air conditioner provided with same

Abstract

The invention relates to a multi-split air conditioner heat recovery system. The multi-split air conditioner heat recovery system comprises an outdoor unit, two or more indoor units, a hot water generator and a mode converter. The outdoor unit comprises a high-pressure air pipe, a low-pressure air pipe and a liquid pipe. Each indoor unit comprises double refrigerant pipes. The mode converter is used for making the double refrigerant pipes communicate with any two of the high-pressure air pipe, the low-pressure air pipe and the liquid pipe correspondingly, so that refrigerant loops are formed. According to the multi-split air conditioner heat recovery system, a high-pressure refrigerant inlet pipe and a refrigerant liquid pipe of the hot water generator communicate with the high-pressure air pipe and the liquid pipe of the outdoor unit correspondingly, so that a refrigerant loop is formed between the hot water generator and the outdoor unit; the hot water generator can absorb heat carried in high-temperature and high-pressure refrigerant in the high-pressure air pipe of the outdoor unit; heat recovery water production of a multi-split air conditioner is achieved; and diversified utilization of recovered heat of the multi-split air conditioner is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a heat recovery system for a multi-connected air conditioner and a multi-connected air conditioner having the same. Background technique [0002] At present, most of the heat recovery systems of multi-connected air conditioners are used for air conditioning applications, which are only used to achieve cooling or heating functions, and do not make diversified use of the recovered heat. Solar energy is a kind of clean energy. As a traditional energy-saving hot water product, solar water heating systems have been used by many families. However, solar water heating systems are affected by meteorological factors such as sunlight, and have poor heating stability, resulting in poor user experience during use. How to make full use of the heat recovered by multi-connected air conditioners and how to improve the heating stability of the solar water heating system are urgent problems to be s...
