The embodiment of the present application discloses a fan overload protection control method, device, computer equipment and storage medium; the method includes: receiving a fan start signal, detecting whether the fan is overloaded; if the fan overload is detected, accumulating the fan overload times; calculating The accumulated time for defrosting and heating after the fan is turned on for the first time; based on the corresponding relationship between the accumulated time for defrosting and heating and the overload of the fan, the overload shutdown control of the unit is performed; in the embodiment of the present application, the accumulated time for defrosting and heating is used as the fan overload. Judgment basis for protection control. When the number of fan overloads reaches the preset threshold, the cumulative duration of defrosting and heating is judged, and whether the fan is overloaded due to frost on the fan is judged. When the fan is overloaded, the fan is effectively and timely. Protection to avoid irreversible damage to the fan; it can effectively reduce the frequency and probability of overloading the fan, and increase the service life of the fan.
Description
technical field [0001] The embodiments of the present application relate to the technical field of heat pumps, and in particular, to a fan overload protection control method, device, computer equipment, and storage medium. Background technique [0002] A heat pump is a device that can obtain low-level thermal energy from natural air, water or soil, and perform work through electrical energy to provide high-level thermal energy that can be used by people. At present, heat pump systems are widely used in heating and cooling fields. Existing low-temperature heat pumps are usually installed in outdoor environments. During operation, when used in different regions, external factors are different. Among them, the environmental temperature and relative humidity are different. All will affect the length of the frosting time, especially when the rain and snow weather occurs, the frosting time will be shortened sharply. During the investigation, it was found that the frequency and pr...
