Abstract

The invention discloses an air conditioning system. The air conditioning system comprises a first refrigerant circulation loop and a second refrigerant circulating loop, wherein the first refrigerantcirculation loop comprises an outdoor heat exchanger, a gas-liquid separator, a first compressor and an indoor heat exchanger which are arranged in series, the second refrigerant circulating loop comprises a first heat exchanger, a throttling device, a second heat exchanger and a second compressor which are sequentially connected in series, and the second heat exchanger is arranged at the periphery and / or the bottom of the gas-liquid separator. The invention further provides a control method of the air conditioning system. rapid heating starting can be achieved through the air conditioning system in a low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a control method thereof. Background technique [0002] For air-conditioning systems, especially multi-connected systems, when the outdoor ambient temperature is too low, the refrigerant inside the air-conditioning system is in a liquid state. At this time, it is difficult for the refrigerant to flow, and it takes a long time for the refrigerant to enter the cycle, which makes the heating start of the air-conditioning system slower. , affecting user experience. Contents of the invention [0003] Based on this, it is necessary to address the problem of slow heating start of the air conditioning system in a low temperature environment, and provide an air conditioning system and a control method thereof with a fast heating start in a low temperature environment and good user experience. [0004] An air conditioning system comprising: [00...
