Embodiment Construction

[0017] The present invention proposes a cold storage and a defrosting control method for the cold storage. The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 The schematic diagram of the structure of the cold storage is shown. The cold storage proposed by the present invention is composed of a plurality of cold storage units 1 assembled together. Each cold storage unit 1 is a complete refrigeration unit, that is, each cold storage unit 1 has its own Independent refrigerating equipment, each refrigerating equipment includes a controller 11 for controlling the switching operation mode of the refrigerating equipment.

[0019] The controllers 11 of a plurality of cold storage units 1 constituting the cold storage are connected to form a complete control system, which also includes a host computer, which has the highest control authority, and the host compute...

Abstract

The invention discloses a refrigeration house and a defrosting control method thereof, the refrigeration house comprises a plurality of refrigeration house units comprising refrigeration equipment, and the refrigeration equipment comprises a controller; when all the refrigeration house units in the refrigeration house reach a defrosting mode, one batch of refrigeration house units begin to defrost, and the other refrigeration house units are stopped and wait for batch-by-batch defrosting; when a part of the refrigeration house units in the refrigeration house reaches a defrosting mode, the refrigeration house units meeting the defrosting condition begin to defrost, and the refrigeration house units not meeting the defrosting condition are switched into a reverse defrosting mode; and if therefrigeration house units which do not meet the defrosting condition reach the defrosting condition in the defrosting process of the refrigeration house units, the refrigeration house units which meet the defrosting condition later are stopped, and the refrigeration house units which meet the defrosting condition return to the normal refrigeration mode after defrosting is completed, so that the problem of temperature rise caused by defrosting is reduced to the maximum extent, and excessive temperature fluctuation of the refrigeration house is avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a cold storage and a defrosting control method thereof. Background technique [0002] In the field of refrigeration, moisture will condense into a frost layer on the surface of the evaporator, and this layer of frost will hinder the heat exchange of the evaporator, thereby affecting the cooling effect, in order to ensure good cooling capacity. When the cold storage reaches the defrosting condition, the cold storage enters the defrosting mode. During the defrosting process, because the temperature of the cold storage will rise, the temperature of the cold storage will fluctuate too much, which will affect the quality of the food stored in the cold storage. Contents of the invention [0003] The invention provides a cold store and its defrosting control method, which solves the problem of temperature rise caused by defrosting in the existing refrigeration technology.
