Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] For better understanding, refer to figure 1 , figure 1 It is a schematic diagram of the structure of a traditional air conditioner.

[0035] by figure 1 As an example to describe the circulation process of the existing refrigerant, since the operation of the compressor is involved in both cooling mode and cooling mode, it is described in two scenarios of cooling mode and heating mode, specifically:

[0036] 1) When the air conditioner receives an instruction to turn on the cooling mode, the compressor 10 compresses the gaseous refrigerant separated from the gas-liquid separator 11, and the compressed high-temperature and high-pressure refrigerant ga...

Abstract

The invention discloses an air conditioner. The air conditioner comprises a refrigerant circulation loop composed of a compressor with a gas-liquid separator, a four-way valve, an outdoor exchanger and an indoor heat exchanger; the air conditioner further comprises a throttling device arranged on the refrigerant circulation loop; the throttling device is formed by connecting a throttling assembly and a control valve; one end of the throttling device is connected with the outdoor exchanger, the other end of the throttling device is connected with the indoor heat exchanger, and the invention further discloses an air conditioner control method and device and a computer readable storage medium; through the throttling assembly and the control valve of the throttling device, the flow of refrigerants flowing through the position between the outdoor exchanger and the indoor heat exchanger is controlled, the flow of flowing refrigerants is reduced, the refrigerant flow flowing back to the compressor is reduced, and therefore the exhaust temperature and the compressor bottom temperature during system running can be improved, the bottom overheat degree and the exhaust overheat degree of the compressor are improved, and the reliable running of the compressor can be ensured.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner, its control method, device and computer-readable storage medium. Background technique [0002] The air conditioner is under partial load conditions, such as the minimum load cooling condition stipulated by the national standard (the temperature of the inner working condition is 21 / 15°C, the temperature of the outer working condition is 18°C), and the maximum load heating condition (the temperature of the inner working condition is 27°C , outside working condition temperature 24 / 18℃), the operating frequency of the compressor is low, if the throttling component under the rated working condition is still used, the refrigerant throttling effect is poor, and the amount of circulating refrigerant in the system is too much, causing the compressor to exhaust The temperature and the temperature at the bottom of the compressor are relatively low. At th...
