Heat pump defrosting exit control method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention discloses a heat pump defrosting exit control method and device, electronic equipment and a storage medium. According to the technical scheme provided by the embodiment of the invention, a condition parameter threshold value for identifying that a heat pump exits a defrosting program is preset, a defrosting exiting moment of each defrosting period of the heat pump is determined based on the condition parameter threshold value, interval time between two adjacent defrosting periods is determined by combining a defrosting entering moment of each defrosting period, whether the interval time is shortened or not is judged by comparing two adjacent interval time, and if the interval time is shortened, the condition parameter threshold value is corrected according to a set correction value. By the adoption of the technical means, the defrosting exit condition of the heat pump can be adaptively corrected, the situation that a frost layer of an evaporator can be removed as far as possible is ensured, the situation that the frost layer is accumulated and expanded due to incomplete defrosting is avoided, then the energy efficiency of the heat pump is guaranteed, and operation faults are avoided.

Description

technical field [0001] The embodiments of the present application relate to the technical field of heat pumps, and in particular, to a heat pump defrosting exit control method, device, electronic device, and storage medium. Background technique [0002] During the use of low-temperature heat pumps, the evaporator often freezes. In order not to affect the energy efficiency and normal use of the heat pump, it is necessary to control the heat pump to perform the evaporator self-defrosting operation. During the defrosting process of the heat pump, the timing for the heat pump to exit the defrosting program will be determined according to the preset defrosting exit conditions. When the heat pump reaches the defrosting exit condition, the heat pump will control the exit of the defrosting program, so as to realize the heat pump self-defrosting function. [0003] However, in the current defrosting process of the heat pump, it often occurs that the defrosting exit condition is reach...

AI Technical Summary

Problems solved by technology

[0003] However, in the heat pump defrosting process at present, it often happens that the frost layer on the evaporator is not completely removed, and the defrosting exit condition is reached.

As a result, the unremoved frost layer on the evaporator will affect the heating capacity of the unit when the heating continues in the next cycle, resulting in a decrease in the heating efficiency of the unit, increasing energy consumption, and failing to meet the water temperature requirements of the heat pump unit

Moreover, due to incomplete defrosting, the frost layer will gradually evolve into an ice layer, resulting in the inability to completely defrost in the next cycle of defrosting.

Even with the passage of time, the ice area will continue to accumulate and expand, which will eventually lead to the failure of the unit to defrost or even malfunction
