Embodiment 1

[0030] An embodiment of the present application provides a method for controlling a heat pump, and the method is applied to a heat pump unit.

[0031] Combine below figure 1 The heat pump control method provided in the embodiment of the present application is introduced in detail. Such as figure 1 As shown, the method includes the following steps:

[0032] Step S102, obtaining the inlet water temperature and outlet water temperature of the heat pump;

[0033] In the embodiment of the present application, the inlet water temperature and the outlet water temperature can be collected by thermocouples deployed at the water inlet and outlet of the heat pump, wherein the temperature collected by the thermocouple deployed at the water inlet of the heat pump is used as the inlet water temperature , the temperature collected by the thermocouple deployed at the water outlet of the heat pump is taken as the outlet water temperature.

[0034] Step S104, based on the inlet water temper...

Embodiment 2

[0042] Such as figure 2 As shown, the method includes the following steps:

[0043] Step S202, controlling the temperature of the environment where the heat pump is located to be the preset ambient temperature;

[0044] In this embodiment, the preset ambient temperature may be a temperature determined according to the actual usage of the heat pump, for example, it may be -10°C or -20°C.

[0045] In an exemplary embodiment of the embodiment of the present application, an experiment may be carried out in an enthalpy difference laboratory to determine the relationship between the inlet water temperature, the outlet water temperature and the pipeline temperature of the heat pump. Specifically, in order to accurately simulate the actual use of the heat pump, the temperature outside the enthalpy difference laboratory can be lowered to about -10°C and -20°C respectively for experiments.

[0046] Step S204, controlling the operation of the heat pump until the water temperature of t...

Embodiment 3

[0068] The method for controlling a heat pump provided in the embodiment of the present application may be applied to a heat pump. In the embodiment of the present application, the whole method can be divided into an experiment flow and a control flow.

[0069] Among them, the experimental process is as follows:

[0070] First, prepare a set of heat pumps outside the enthalpy difference laboratory. The temperature outside is reduced to about -10°C. Turn off the machine at about ℃, when the water temperature drops, the machine will not turn on automatically, and then start to record the temperature at this time t=50, and then record the temperature of the water in and out and the corresponding thermocouple temperature every hour, and record the temperature of the three thermocouples 6 ℃, 4°C, 2°C and the corresponding inlet and outlet water temperatures, record 3 groups, the outlet water temperature is t 出水1 , t 出水2 , t 出水3 , the corresponding three temperatures of the inco...

Abstract

The embodiment of the invention discloses a heat pump control method, device and system, a storage medium and related equipment, and belongs to the technical field of heat pumps. The method comprisesthe steps that the water inlet temperature and the water outlet temperature of a heat pump are obtained; based on the water inlet temperature and the water outlet temperature, the target pipeline temperature is determined, and the target pipeline temperature is used for representing the temperature of the middle position of a pipeline of the heat pump; and the heat pump is controlled to perform anti-freezing operation based on the target pipeline temperature. Therefore, according to the embodiment of the invention, the heat pump can be controlled to perform anti-freezing operation through thetarget pipeline temperature, and the heat pump anti-freezing aim is achieved; and therefore, the technical effects of achieving accurate and real anti-freezing aims, improving the anti-freezing efficiency, saving more energy and being more effective are achieved, and then the technical problems that in the prior art, an anti-freezing control method is low in accuracy, the anti-freezing effect is poor, and power consumption is large are solved.

Description

technical field [0001] The present application relates to the field of heat pumps, in particular, to a heat pump control method, device and system, storage medium and related equipment. Background technique [0002] At present, in order to prevent the heat pump from being damaged by freezing in a low temperature environment, antifreeze control can be carried out according to the inlet water temperature and outlet water temperature of the heat pump unit, and the antifreeze control level can be divided into first-level antifreeze, second-level antifreeze and third-level antifreeze. However, the existing antifreeze control methods are not accurate enough. Turning on antifreeze when antifreeze is not needed will lead to increased power consumption, and the inlet water temperature and outlet water temperature do not represent the real antifreeze temperature. The inlet water temperature and outlet water temperature may be higher. There is still a risk of freezing damage. [0003]...
