Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0023] figure 1 is a flowchart of an anti-icing control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0024] Step S101, monitoring the inlet water temperature and outlet water temperature of the heat exchanger;

[0025] Step S102 , according to the average value of the inlet and outlet water temperatures, correspondingly adjust the number of steps of the electronic expansion valve. Among them, the average value of the inlet and outlet water temperature = (inlet water temperature + outlet water temperature) / 2.

[0026] In this embodiment, the number of steps of the electronic expansion valve is adjusted by the temperature of the inlet and outlet water of the heat exchanger, which solves the problem th...

Abstract

The invention discloses a method and device for control over icing prevention and a generator. The method includes the steps that water inlet temperature and water outlet temperature of a heat exchanger are monitored; according to a water inlet temperature value and a water outlet temperature value, the step number of an electronic expansion valve is correspondingly adjusted. Through the water inlet temperature and the water outlet temperature of the heat exchanger, the step number of the electronic expansion valve is adjusted, the problem that in the prior art, water is prone to icing when a generator performs refrigeration is solved, a pipeline get smoothened, the amount of outlet water is more stable, and the condition that when severe icing occurs, the internal structure of a plate heat exchanger is expanded and damaged is prevented.

Description

technical field [0001] The present invention relates to the technical field of generators, in particular to an anti-icing control method, device and generator. Background technique [0002] When the generator is cooling water, the evaporation temperature of the refrigerant is too low and the pressure is too low, which will easily cause the water flowing in the generator to freeze. Slight icing will block the internal pipeline, reduce the water output and reduce the heat exchange efficiency, cause the generator to work unstable, reduce the working capacity, and affect the user experience; severe icing will cause the plate heat exchanger (also called plate heat exchanger) ) The internal structure is cracked and damaged. [0003] Aiming at the problem in the prior art that the cooling water of the generator is easy to freeze, no effective solution has been proposed so far. Contents of the invention [0004] Embodiments of the present invention provide an anti-icing control ...
