Air conditioning system and cold media adjusting method thereof

Abstract

The invention provides an air conditioning system and a cold media adjusting method of the air conditioning system. The air conditioning system comprises an air conditioner; a detector, which is used for detecting working parameter when the air conditioner is in running; a cold media adjusting device, which comprises a first electromagnetic valve and a second electromagnetic valve; a liquid storage tank, of which inlet is connected to a pipeline between an outdoor heat exchanger and a throttle device through the first electromagnetic valve, and outlet is connected to a pipeline between a gas-liquid separator and a four-way valve through the second electromagnetic valve; a controller, which is respectively connected with the detector, the first electromagnetic valve and the second electromagnetic valve, and adjusts the cold media amount in a cold media circulating loop through controlling the first electromagnetic valve and the second electromagnetic valve when it judges that the cold media amount in the cold media circulating loop not satisfies the preset conditions according to the working parameter. The air conditioning system and the cold media adjusting method of the air conditioning system can adjust the cold media amount specific to loads under different working conditions, improve the running reliability, and improve the using comfort level.

Description

technical field [0001] The invention relates to an air-conditioning system and a refrigerant regulating method of the air-conditioning system. Background technique [0002] The air-conditioning system is a common system for cooling and heating. When the air-conditioning system operates under different load conditions, the amount of refrigerant required by the system is different. Under normal conditions, the amount of refrigerant required by the air-conditioning system is relatively small. For example, when the air-conditioning system is running under low-temperature conditions such as heating with a small load, the effect is better if the amount of refrigerant required by the system is relatively larger. However, in the prior art, the air-conditioning system usually operates with a fixed amount of refrigerant, so that when some large loads or small loads do not require too much or too little refrigerant, the operating pressure, temperature and other parameters of the air-co...

Problems solved by technology

However, in the prior art, the air-conditioning system usually operates with a fixed amount of refrigerant, so that when some large loads or small loads do not require too much or too little refrigerant, the operating pressure, temperature and other parameters of the air-conditioning system exceed the required range. Affect the reliability of the air conditioning system operation, and the comfort of the air conditioning system
