Embodiment 1

[0053] Such as figure 1 As shown, in the embodiment of the first aspect of the present invention, a method for controlling refrigeration equipment is provided, including:

[0054] Step S102, obtaining the operating parameters of the refrigeration equipment, and obtaining the outlet water temperature of the refrigeration equipment;

[0055] Step S104, determine that the operating parameters meet the unloading condition, and the outlet water temperature is lower than or equal to the first outlet water temperature, control the refrigeration equipment to perform load unloading operation until the outlet water temperature is higher than or equal to the second outlet water temperature, and stop performing the load unloading operation.

[0056] Wherein, the second outlet water temperature is higher than the first outlet water temperature.

[0057] Such as figure 2 As shown, the control method of the refrigeration equipment also includes:

[0058] Step S202, receiving the setting ...

Embodiment 2

[0072] In an embodiment of the present invention, the load unloading operation includes: controlling the refrigeration equipment to suspend work; and stopping the load unloading operation, specifically including: restarting the refrigeration equipment.

[0073] In this embodiment, the load unloading operation includes controlling the refrigeration equipment to suspend work, that is, when the operating parameters meet the unloading conditions, the refrigeration equipment enters the suspension working state. The outlet water temperature is lower than the water temperature set by the user. When the outlet water temperature is higher than the second outlet water temperature, the refrigeration equipment is controlled to restart, at this time, the compressor is turned on, and the refrigeration equipment is put into operation again.

[0074] Specifically, the first outlet water temperature is the target outlet water temperature set by the user, and the second outlet water temperature...

Embodiment 3

[0076] In one embodiment of the present invention, the refrigeration equipment further includes a heating device configured to increase the outlet water temperature, and the load unloading operation includes: starting the heating device; and stopping the load unloading operation, specifically including: turning off the heating device.

[0077] In this embodiment, the refrigeration unit includes heating means and the load shedding operation includes activating the heating means. Specifically, the heating device specifically includes a hot gas bypass. When the operating parameters meet the unloading conditions, the hot gas bypass is turned on to reheat the outlet water pipeline with the heat of the compressor or evaporator, and the outlet water is increased without turning off the compressor. Water temperature, until the outlet water temperature is higher than the second outlet water temperature, close the hot gas bypass. During this process, the cooling unit remains on.

Abstract

The invention provides a control method and a system of refrigeration equipment, the refrigeration equipment and a readable storage medium, wherein the control method of the refrigeration equipment comprises the following steps of: acquiring operating parameters of the refrigeration equipment and acquiring an outlet water temperature of the refrigeration equipment; determining that the operating parameters meet the unloading conditions and the outlet water temperature is lower than or equal to a first outlet water temperature, controlling the refrigeration equipment to perform the load unloading operation until the outlet water temperature is higher than or equal to a second outlet water temperature, and stopping the load unloading operation, wherein the second outlet temperature is higherthan the first outlet temperature. According to the technical scheme provided by the invention, when an unloading mode is exited, a trigger temperature for stopping the load unloading operation is increased to the second outlet temperature, so that after the unloading mode is stopped, a unit can be ensured to maintain an operating state for a period of time, repeated unloading caused by lower working conditions of users is avoided, fluctuation of outlet water temperature is effectively reduced, and user experience is ensured.

Description

technical field [0001] The present invention relates to the technical field of refrigeration equipment, in particular, to a control method of refrigeration equipment, a control system of refrigeration equipment, a refrigeration equipment and a computer-readable storage medium. Background technique [0002] In the related technology, when the user's working condition is low and the frequency of the guide vane and the compressor are close to the minimum value, the unit will enter the unloading state, and once the water temperature rises above the target temperature calibrated by the user, the unit will start again. Therefore, when the user's working condition is maintained in a low range, the unit will frequently perform unloading operations, resulting in large fluctuations in water temperature and poor user experience. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0...
