The invention discloses an air-conditioning system and a control method for improving refrigeration and heating capacity, including a compressor, a four-way valve, a gas-liquid separator, an indoor heat exchanger and an outdoor heat exchanger, and an auxiliary heat exchange branch circuit, Wherein, the two ends of the auxiliary heat exchange branch are respectively bypassed and connected in parallel to the main road of the air conditioning system between the indoor heat exchanger and the outdoor heat exchanger, and the auxiliary heat exchange branch is provided with a section that is installed in the gas-liquid separator. The heat exchange section in the cavity, the auxiliary heat exchange branch is based on whether the real-time temperature value of the inner cavity of the gas-liquid separator reaches the preset parameter state, correspondingly starts or closes the auxiliary heat exchange branch, so that the main air conditioning system The refrigerant in the circuit is introduced into the gas-liquid separator through the auxiliary heat exchange branch for heat exchange.
Description
technical field [0001] The invention relates to the technical field of air-conditioning systems, in particular to an air-conditioning system and a control method for increasing cooling and heating capacity. Background technique [0002] When the existing air-conditioning system is running in refrigeration, the cooling capacity contained in the refrigerant in the gas-liquid separator is not used reasonably, and the energy is wasted; while in the heating operation of the air-conditioning system, often because the ambient temperature is too low, the refrigerant Incomplete heat exchange in the outdoor heat exchanger, resulting in low pressure and low heating capacity. [0003] Therefore, how to utilize the refrigerant with incomplete heat exchange is an important technical problem to effectively improve the cooling / heating effect of the air-conditioning system, and it is a technical problem that practitioners urgently need to solve. Contents of the invention [0004] The obje...
