The invention relates to the technical field of air conditioners, and provides a multi-mode water-circulation multi-split air-conditioning system. The multi-mode water-circulation multi-split air-conditioning system comprises a plurality of air-conditioner units, a second circulating pump, a stop valve and a natural energy acquisition device. Each air-conditioner unit comprises a plurality of indoor heat exchangers. The indoor heat exchangers of each air-conditioner unit are three-medium heat exchangers each provided with an indoor first medium channel and an indoor second medium channel. Thefirst ends of all the indoor second medium channels communicate with a first main pipe, and the second ends of all the indoor second medium channels communicate with a second main pipe. An outlet of the natural energy acquisition device communicates with the first main pipe through a first circulating pump, and an inlet of the natural energy acquisition device communicates with the second main pipe. An inlet of the second circulating pump communicates with the first main pipe, and an outlet of the second circulating pump communicates with the second main pipe. The stop valve is arranged on thefirst main pipe. An outlet of the first circulating pump is located in the inlet side of the stop valve, and the inlet of the second circulating pump and the first end of all the indoor second mediumchannels are located on the outlet side of the stop valve. According to the multi-mode water-circulation multi-split air-conditioning system, the air-conditioner units can stably and efficiently operate all year round.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a multi-mode water ring multi-connected air conditioning system. Background technique [0002] Building energy consumption accounts for a high proportion of the total energy consumption of society, and HVAC energy consumption is the main part of building energy consumption. Therefore, optimizing the air conditioning system is an important way to reduce the total energy consumption of society and realize energy saving and emission reduction. [0003] At present, the air-cooled multi-connected air-conditioning system is not only widely used in office buildings, hotels, schools and other public buildings, but also has been greatly promoted in residential buildings. Relevant statistics show that in recent years, the market share of air-cooled multi-connected air-conditioning systems in various air-conditioning products has exceeded 50%. [0004] Although the air-cooled mult...
