Problems solved by technology

At this time, the refrigerant will absorb the heat of the outdoor environment in the outdoor heat exchanger, or release heat to the indoor environment in the indoor heat exchanger, which invisibly causes the loss of energy of the air conditioning system.
[0004] In addition, after the air conditioning system is restarted, it takes a long time to establish the system pressure difference and the optimal distribution of refrigerant in the system, resulting in a lag in the cooling / heating capacity at the beginning of the start-up, making it difficult to meet the needs of users for rapid cooling / heating

Abstract

The invention discloses an air conditioning system and a running method thereof. The air conditioning system comprises a compressor, a four-way valve, an indoor heat exchanger, a throttling device and an outdoor heat exchanger which sequentially communicate with one another to form a refrigerant circulating loop, wherein control valves used for controlling on-off of a pipeline are also formed on the pipeline of the air conditioning system and are composed of first control valves formed on the pipeline between the indoor heat exchanger and the outdoor heat exchanger. According to the technical scheme of the invention, by closing the added first control valves, the pipeline circulating between the indoor heat exchanger and the outdoor heat exchanger is blocked, and a refrigerant is prevented from mutually migrating between the indoor heat exchanger and the outdoor heat exchanger, so that on one hand, loss of energy of the air conditioning system is prevented; and on the other hand, the system pressure difference of the air conditioning system in the running state can be kept, the system pressure difference and optimal distribution of the refrigerant in the system can be rapidly established when the air conditioning system starts at a next time, and the requirement for rapid refrigeration / heating is met.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and an operating method thereof. Background technique [0002] The air-conditioning system compresses the refrigerant through the compressor, so that the refrigerant performs heat exchange between the indoor side and the outdoor side, so as to achieve the purpose of adjusting the indoor temperature. Taking refrigeration as an example, the compressor compresses the refrigerant into a high-temperature and high-pressure gaseous state and sends it to the outdoor heat exchanger. The low-temperature and low-pressure liquid refrigerant that has been depressurized by the throttling device is vaporized into a low-temperature and low-pressure gaseous refrigerant in the indoor heat exchanger, and at the same time absorbs the heat in the indoor environment, and finally returns to the compressor to form a refrigeration cycle. [0003] It can be seen that d...
