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] like 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 the...

Abstract

The invention provides a capillary tube control method and device of an air conditioner, the air conditioner and a storage medium, and relates to the technical field of air conditioners. Capillary tubes comprise the first capillary tube, the second capillary tube and the third capillary tube which are arranged in parallel. The control method comprises the steps that when the air conditioner operates in a refrigeration mode, the first capillary tube is started; the outdoor temperature, the exhaust temperature and the outer coil pipe pressure are obtained; when the outdoor temperature, the exhaust temperature and the outer coil pipe pressure meet a first preset condition, the first capillary tube is closed, and the second capillary tube is opened; and when the outdoor temperature, the exhaust temperature and the outer coil pipe pressure meet a second preset condition, the first capillary tube is closed, and the third capillary tube is opened. Thus, the three capillary tubes with different lengths are installed in parallel, the load condition of an outdoor unit is judged by obtaining the outdoor temperature, the exhaust temperature and the outer coil pipe pressure in different scenes,the capillary tubes with different lengths are selected according to the different load conditions, and therefore adjustment of the refrigerating capacity is achieved.

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...
