Abstract

The invention relates to a multi-split air conditioning system. A compressor, an outdoor heat exchanger and an indoor heat exchanger form a connection loop through two four-way valves, electronic expansion valves, electromagnetic valves, wherein a terminal a of a first four-way valve is connected with the refrigerant outlet of the compressor; the terminal d of the first four-way valve is connected with the terminal w of a second four-way valve by virtue of a check valve; the terminal c of the first four-way valve is connected with the terminal y of the second four-way valve in parallel and then is connected with the refrigerant inlet of the compressor by virtue of a gas-liquid separator; the terminal w of the second four-way valve is connected with the refrigerant outlet of the compressor through a first electromagnetic valve; the terminal x of the second four-way valve is sequentially connected with the outdoor heat exchanger, a high pressure liquid storage tank, a second electromagnetic valve, a second electronic expansion valve, an indoor unit electronic expansion valve and the terminal s1 of the indoor heat exchanger; and the terminal s2 of the indoor heat exchanger is connected with the terminal b of the first four-way valve. The multi-split air conditioning system disclosed by the invention is mainly applied to a heat pump air conditioning hot water system and has an ice storage function. The multi-split air conditioning system disclosed by the invention can save more energy, and has high working efficiency and wider practical range.

Description

technical field [0001] The invention relates to an air conditioning system, in particular to a multi-connected air conditioning system. Background technique [0002] Traditional multi-connected air conditioners generally include cooling and heating heat pump air conditioners, or hot water heaters, or air conditioner heaters with cooling, heating, hot water heating and simultaneous cooling and heating functions, or Energy-saving air conditioners with cold storage function, these systems provide to a certain extent the constant ambient temperature, humidity and hot water needs in people's daily life, such as air conditioner hot water machines to a large extent meet the needs of people's air conditioning and heating Water needs, but these air conditioners all need an outdoor unit. With the improvement of people's quality of life, people's requirements for quality of life are also getting higher and higher. People's needs for cold, hot, hot water, floor heating, energy saving, e...
