Problems solved by technology

Every time the compressor is stopped and restarted, it will generate a large startup power consumption, and at the beginning of each startup, high-temperature refrigerant will first enter the evaporator and heat up first, and then refrigerate after reaching the conditions of the refrigeration cycle, saving energy. Flow is achieved using capillary tubes

Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Please refer to figure 1 , figure 1 It is a schematic cross-sectional view of an embodiment of the present invention. Such as figure 1 As shown, the electric valve provided in this embodiment includes a valve body 1 and a stator coil (not shown in the figure). The valve body 1 includes a valve seat assembly 11 , a rotor 12 and a valve shaft 14 . The stator coil of the electric valve is connected to the drive controller. After the drive controller is powered on, it will send a pulse drive signal to the stator coil, and the stator coil will generate a periodically changing magnetic field, thereby driving the rotor 12 of the electric valve to rotate forward or reverse.

[0029] The rotor 12 is fixedly connected to...

Description

【Technical field】 [0001] The invention relates to the technical field of refrigeration control, in particular to an electric valve. 【Background technique】 [0002] Refrigeration and refrigeration equipment such as refrigerators are widely used in various occasions. Taking refrigerators as an example, each temperature zone of the refrigerator is controlled according to a certain range of preset temperatures, that is, intermittent refrigeration. When the preset temperature is reached, the compressor stops; When the actual temperature in the temperature zone is higher than the preset temperature, the compressor starts to refrigerate, so that the temperature in the temperature zone reaches the preset temperature. Every time the compressor is stopped and restarted, it will generate a large startup power consumption, and at the beginning of each startup, high-temperature refrigerant will first enter the evaporator and heat up first, and then refrigerate after reaching the conditio...
