Embodiment 1

[0032] In the preferred embodiment 1 of the present invention, a defrosting control method for refrigeration equipment is provided. This control method can be directly applied to various air-conditioning units, especially condensing units. Condensing units are widely used in various cold storages. The operating condition is lower than that of ordinary air conditioners, and the running time is long, so the problem of frosting is relatively serious. Adopting the defrosting control method in the present invention can achieve a good defrosting effect. Specifically, figure 1 An alternative flowchart showing the method, such as figure 1 As shown, the method includes the following steps S102-S106:

[0033] S102: When the refrigeration equipment meets the defrosting exit condition, control the refrigeration equipment to exit defrosting;

[0034] S104: Determine the defrosting completion status according to the defrosting exit condition;

[0035]S106: Correct the defrosting entry co...

Embodiment 2

[0088] Based on the method for controlling defrosting of refrigeration equipment provided in Embodiment 1 above, a defrosting control device for refrigeration equipment is also provided in preferred embodiment 2 of the present invention, specifically, Figure 5 shows an optional structural block diagram of the device, such as Figure 5 As shown, the device includes:

[0089] A detection module 502, configured to control the refrigeration equipment to exit defrosting when the refrigeration equipment meets the defrosting exit conditions;

[0090] Determining mode 504, used to determine the completion of defrosting according to the defrosting exit condition;

[0091] The adjustment module 506 is used for correcting the defrosting entry condition according to the defrosting completion situation.

[0092] In the above embodiments, a defrosting control scheme for refrigeration equipment is proposed. After the refrigeration equipment meets the defrosting exit conditions and exits d...

Embodiment 3

[0105] Based on the refrigeration equipment control device provided in the above-mentioned embodiment 2, a condensing unit is further provided in preferred embodiment 3 of the present invention, including the above-mentioned refrigeration equipment control device.

[0106] In the above embodiments, a defrosting control scheme for refrigeration equipment is proposed. After the refrigeration equipment meets the defrosting exit conditions and exits defrosting, the completion of defrosting is determined according to the defrosting exit conditions, and then the defrosting is corrected according to the completion of defrosting. Entering conditions, that is, to adjust the defrosting control method in real time to improve the defrosting effect, thereby solving the problem of incomplete defrosting or too long defrosting time caused by the simple defrosting control scheme in the prior art, and improving the defrosting effect. Intelligent frost control and defrosting effect.

Abstract

The invention discloses a defrosting control method and device for refrigeration equipment and a condensing unit. The method comprises the steps that when the refrigeration equipment meets a defrosting quit condition, the refrigeration equipment is controlled to quit defrosting; a defrosting completion condition is determined according to the defrosting quit condition; and a defrosting entering condition is corrected according to the defrosting completion condition, wherein the corrected defrosting entering condition is used for judging whether the refrigeration equipment enters defrosting or not. According to the defrosting control method and device, the problem that in the prior art, due to the fact that a defrosting control scheme is simple, defrosting is incomplete or the defrosting time is too long is solved, the defrosting entering condition is corrected according to the defrosting completion condition, and the intelligence of defrosting control and the defrosting effect are improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a defrosting control method and device for refrigeration equipment and a condensing unit. Background technique [0002] With the country's strong support for refrigeration, the application of refrigeration has become more and more diversified. Among them, condensing units are widely used in various cold storages, and play the role of storage, storage and pre-cooling in the cold chain. The application conditions of condensing units are generally lower than those of air conditioners, and the running time is long, so the problem of frosting is relatively serious. However, the current defrosting mode usually enters and exits at a fixed time or exits defrosting when a certain temperature is reached, and the operation method is simple. If the defrosting time of this scheme is inaccurate, the defrosting exits early, and there will be problems of incomplete defrosting, an...
