Embodiment Construction

[0051] The control method in the embodiment of the present invention can be applied to a refrigeration system, and there can be M valves in the refrigeration system, where M can be a positive integer, and the method can include: determining N valves that need to work from the M valves For valves, N is an integer not less than 1 and not greater than M; determine whether N is greater than the first preset value; if N is greater than the first preset value, determine the first phase that needs to be excited among the N valves Whether the value is greater than the second preset value, the first phase value is the total phase value that needs to be excited among the N valves; if the first phase value is greater than the second preset value, control the The N valves start to act according to the first preset rule.

[0052] In the embodiment of the present invention, it may first be judged whether the number N of valves to be operated is greater than the first preset number value, an...

Abstract

The invention discloses a control method for reducing energy consumption. The method comprises the following steps: determining N valves needing to work in M valves, wherein N is an integer which is greater than or equal to 1 and smaller than or equal to M; judging whether N is greater than a first preset number value or not; if N is greater than the first preset number value, judging whether the first number value of to-be-excited phases in the N valves is greater than a second preset number value or not, wherein the first number value of to-be-excited phases is the total number value of to-be-excited phases in the N valves; and if the first number value of to-be-excited phases is greater than the second preset number value, controlling the N valves to start acting according to a first preset regulation. The invention further discloses a device and a refrigeration system which are used for realizing the method.

Description

technical field [0001] The invention relates to the field of electronics and control, in particular to a control method, a control device and a refrigeration system. Background technique [0002] The electronic expansion valve is to adjust the liquid supply of the evaporator according to the preset program. Because it belongs to the electronic adjustment mode, it is called an electronic expansion valve. It adapts to the development requirements of refrigeration mechanical and electrical integration, has excellent characteristics that cannot be compared with thermal expansion valves, provides conditions for intelligent control of refrigeration systems, and is a promising self-control energy-saving component. [0003] As a new type of control element, the electronic expansion valve has already broken through the concept of the throttling mechanism. It is an important link in the intelligentization of the refrigeration system, an important means and guarantee for the real reali...
