Problems solved by technology

However, the existing gas-liquid separator has a relatively simple function, and can only play the role of separation and storage. Since the system cannot effectively control the liquid stored in its interior, when the excess liquid is stored in the gas-liquid separator , it is easy to cause the compressor to run too wet, or even produce liquid hammer phenomenon, which will affect the safety and reliability of the system operation

Abstract

The invention discloses an air conditioning system and a method for detecting a liquid level of an air-liquid separator of the air conditioning system. The air conditioning system comprises a compressor, a four-way valve, an outdoor heat exchanger, a throttling device, an indoor heat exchanger, the air-liquid separator and a detecting pipeline. The detecting pipeline is connected among the compressor, the air-liquid separator and the four-way valve and is used for detecting the liquid level of the air-liquid separator. The air conditioning system and the method have the advantages that the internal liquid level of the air-liquid separator is detected and judged, corresponding control is executed by outer machines when the liquid level of the air-liquid separator is higher than a warning liquid level, the internal liquid level of the air-liquid separator is adjusted under output actions of the outer machines and adjustment actions of valves and is within a safety range, problems that return air of a compressor carries liquid, the compressor runs under an excessively wet condition and liquid impact occurs due to an excessively high internal liquid level of an air-liquid separator are solved, safe and reliable running of an outer machine system is guaranteed, and drifting among the outer machines in the multi-machine system can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a liquid level detection method of a gas-liquid separator thereof. Background technique [0002] In the air conditioner multi-connected system, the gas-liquid separator is an important component, which plays the role of separating the liquid contained in the return air and storing the excess refrigerant due to the change of the system output. However, the existing gas-liquid separator has a relatively single function, and can only play the role of separation and storage. Since the system cannot effectively control the liquid stored in its interior, when the excess liquid is stored in the gas-liquid separator , It is easy to cause the compressor to run in excessive humidity, and even produce liquid hammer phenomenon, which will affect the safety and reliability of the system operation. Contents of the invention [0003] The main purpose o...
