Embodiment Construction

[0030] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] The air conditioning system of the present invention, as figure 1 As shown, the air conditioning system includes: a processor 1001, such as a CPU, a user interface 1002, a memory 1003, a communication bus 1004, and a control program stored in the memory and operable on the processor. Wherein, the communication bus 1004 is used to realize connection and communication between these components. The user interface 1002 may include a display screen (Display), an input unit such as a remote controller. The memory 1003 can be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1003 may also be a storage device independent of the foregoing processor 1001 .

[0032] The air conditioning system may also include an indoor unit, an outdoor unit, a flash evapor...

Abstract

The invention discloses a controlling method for an air conditioning system. The controlling method for the air conditioning system comprises the following steps that a gas discharging temperature of a compressor of the air conditioning system is acquired; when the gas discharging temperature is greater than a first preset temperature, an electronic expansion valve of the air conditioning system is controlled to open a first reserved opening degree, so that gaseous low temperature refrigerant after gas-liquid separation in a flash evaporator of the air conditioning system and the gas in a gas discharging outlet of the compressor are confluent, and gas discharging pressure and the gas discharging temperature are reduced accordingly; when the gas discharging temperature reaching a second preset temperature is monitored, an opening degree of the electronic expansion valve is turned down or the electronic expansion valve is closed, so that gas confluence between the gas after the gas-liquid separation in the flash evaporator of the air conditioning system and the gas in the gas discharging outlet is reduced, or the gas confluence between the gas after the gas-liquid separation in the flash evaporator of the air conditioning system and the gas in the gas discharging outlet is cut off. The invention further provides the air conditioning system and a computer readable storage medium. According to the air conditioning system, the controlling method and the computer readable storage medium, the excessive gas discharging temperature of the compressor of the air conditioning system is prevented through an intermittent control, so that stability of the air conditioning system is improved.

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 and a computer-readable storage medium. Background technique [0002] The operating frequency of the compressor of the air conditioning system can usually run up to 120Hz, but when the compressor operates at a higher frequency, the exhaust temperature will rise sharply, which will reduce the life of the compressor and affect the performance of the air conditioning system. stability. Contents of the invention [0003] The main purpose of the present invention is to provide an air-conditioning system, a control method and a computer-readable storage medium, aiming at preventing the exhaust temperature of the compressor of the air-conditioning system from being too high through intermittent control, thereby improving the stability of the air-conditioning system. [0004] The present invention provides a control method ...
