Embodiment Construction

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] According to an embodiment of the present invention, a defrosting control method for a heat pump unit is provided, such as figure 1 A schematic flow diagram of an embodiment of the method of the present invention is shown. The defrosting control method of the heat pump unit may include: step S110 to step S130.

[0047] At step S110, the outdoor ambient te...

Abstract

The invention discloses a defrosting control method and device for a heat pump unit, a storage medium and the heat pump unit. The method comprises the steps that the outdoor environment temperature and the running state of the heat pump unit are obtained; whether or not the outdoor environment temperature is larger than or equal to the lower limit of a first set temperature range is determined; ifthe outdoor environment temperature is smaller than the lower limit of the first set temperature range, whether the heat pump unit meets set defrosting conditions or not is determined according to the outdoor environment temperature and the running state, and under the condition that the heat pump unit meets the defrosting conditions, the heat pump unit is controlled to enter a set defrosting process. According to the scheme, the problem can be solved that when outdoor unit fins are defrosted, the heat pump unit unreasonably enters the defrosting conditions, the defrosting reliability is poor, and the effect of improving the defrosting reliability is achieved.

Description

technical field [0001] The invention belongs to the technical field of heat pump units, and specifically relates to a defrosting control method, device, storage medium and heat pump unit of a heat pump unit, in particular to a multi-parameter judging defrosting control method of a heat pump water unit, and corresponding to the method A device, a heat pump unit having the device, a computer-readable storage medium storing instructions corresponding to the method, and a heat pump unit capable of executing the instructions corresponding to the method. Background technique [0002] When the heat pump water heater is heating in winter, because it needs to absorb heat from the low-temperature environment, the low evaporation temperature is generally low, which will cause the moisture in the outdoor air to form frost and adhere to the surface of the outdoor heat exchanger when it is cold, increasing the outdoor temperature. The thermal resistance of the heat exchanger causes the he...
