Problems solved by technology
[0003] The main purpose of the present invention is to provide an air-conditioning system, a control method of the air-conditioning system, and a computer-readable storage medium, which solves the problem of the evaporator returning to the compressor due to insufficient evaporation of the evaporator when the air-conditioning system is operating in low-temperature refrigeration mode. The agent is in liquid state, so that the compressor is damaged due to liquid operation

Embodiment Construction
[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The invention provides an air conditioning system, such as figure 1 As shown, in one embodiment, the air conditioning system includes a compressor 1, a condenser 2, an evaporator 3 and a liquid storage tank 4, one end of the compressor 1 is connected to one end of the condenser 2, and the other end of the condenser 2 It is connected with one end of the evaporator 3 , the other end of the evaporator 3 is connected with the other end of the compressor 1 , and the liquid storage tank 4 is arranged at the end of the connection between the compressor 1 and the evaporator 3 . Specifically, in this embodiment, when the air conditioning system is in the low-temperature cooling mode, the compressor 1 runs the low-temperature and low-pressure refrigerant through the motor on the compressor 1 and drives the piston to comp...

The invention discloses an air conditioning system, which includes a compressor, a condenser, an evaporator, a liquid storage tank, a first temperature sensor, a second temperature sensor and a processor. After a set time, obtain the return air temperature of the compressor detected by the first temperature sensor and the inlet temperature of the evaporator detected by the second temperature sensor, and when the temperature difference between the return air temperature and the inlet temperature is less than or equal to the first preset When there is a temperature difference, the excess refrigerant in the evaporator is recovered to the liquid storage tank. The invention also discloses a control method of the air-conditioning system and a computer-readable storage medium. In this way, when the air-conditioning system is running in low-temperature refrigeration mode, due to insufficient evaporation of the evaporator, the refrigerant returned from the evaporator to the compressor is in a liquid state, causing the compressor to run with liquid and damage the problem, thereby improving the performance of the compressor. service life.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system, a control method of the air conditioning system, and a computer-readable storage medium. Background technique [0002] The charging volume of the refrigerant in the traditional air conditioning system is adjusted according to the standard indoor and outdoor temperatures during the development of the air conditioner to achieve the best energy efficiency. Needs change. For example: in the case of low-temperature refrigeration with low outdoor temperature, due to the low outside temperature, the condensation effect of the condenser is excellent, and the required refrigerant demand is small. If the amount of refrigerant is too large, the evaporation will be insufficient. The refrigerant that returns to the compressor is in liquid state. If it is operated with liquid for a long time, it may damage the compressor and bring unnecessary troub...
