Embodiment Construction

[0052]Air conditioners include capillary tubes, and each air conditioner is equipped with a capillary tube that matches the refrigeration system. Capillary tubes directly affect the cooling capacity of the air conditioner. Since there is only one capillary tube, the current fixed-frequency air conditioner cannot adjust the cooling capacity according to the load, and customer satisfaction is low.

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0054] Such as figure 1 As shown, it is a structural schematic diagram of an air conditioner according to an embodiment of the present invention, and the air conditioner includes a compressor 1, a four-way valve 2, a pressure sensor 3, an external fan 4, an outdoor heat exchanger 5 and an indoor heat exchanger 6. The pressure sensor 3 is set in ...

Abstract

The invention provides a capillary control method and device of an air conditioner, an air conditioner and a storage medium, and relates to the technical field of air conditioners. The capillary tube includes a first capillary tube, a second capillary tube and a third capillary tube arranged in parallel, and its control method includes: when the air conditioner operates in cooling mode, open the first capillary tube; obtain the outdoor temperature, exhaust temperature and external disk pressure; when the outdoor temperature , exhaust temperature and external disk pressure meet the first preset condition, close the first capillary, and open the second capillary; when the outdoor temperature, exhaust temperature and external disk pressure meet the second preset condition, close the first capillary, and Turn on the third capillary. In this way, three capillary tubes of different lengths are installed in parallel, and the load of the external unit is judged by obtaining the outdoor temperature, exhaust temperature, and external disk pressure in different scenarios, and capillary tubes of different lengths are selected according to different load conditions to achieve cooling capacity. adjustment.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a capillary control method and device for an air conditioner, an air conditioner and a storage medium. Background technique [0002] The air conditioner has gradually become a necessity of life. In order to use the air conditioner better, people are constantly studying how to make the air conditioner in the best working condition, so as to make the performance of the air conditioner better. [0003] Air conditioners include capillary tubes, and each air conditioner is equipped with a capillary tube that matches the refrigeration system. Capillary tubes directly affect the cooling capacity of the air conditioner. Since there is only one capillary tube, the current fixed-frequency air conditioner cannot adjust the cooling capacity according to the load, and customer satisfaction is low. Contents of the invention [0004] The problem solved by the invention is th...
