Food cold closet capable of reducing cool air loss for refrigeration engineering

Abstract

The invention discloses a food cold closet capable of reducing cool air loss for refrigeration engineering. The food cold closet capable of reducing cool air loss for refrigeration engineering comprises a closet body, closet side plates and a closet bottom plate, wherein a refrigeration ion is connected to the right side of the closet body, a screw compressor is installed in the refrigeration part, the right side of the screw compressor is connected with an evaporator through a connecting pipe, and a condenser is connected to the left side of the screw compressor through a connecting pipe; anelastic switch is arranged in the left side of the closet body and suction fans are fixedly arranged in the closet side plates; suction hoods are connected with the left sides of the suction fans through suction pipes, and the right sides of the suction fans penetrate through the closet side plates through exhaust pipes; and connecting grooves are formed in the surface of the closet bottom plate.According to the food cold closet capable of reducing the cool air loss for the refrigeration engineering, when a closet door is opened, the suction fans inside the side plates work, the dissipated cool air can be sucked back into the closet body, the leakage of the cool air is effectively reduced, heat preservation of the closet body is achieved effectively and the problem of the dissipation of cool air can be avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration engineering, in particular to a food refrigerator for refrigeration engineering that can reduce cold air loss. Background technique [0002] With the development of my country's national economy, the status of refrigeration engineering is becoming more and more important. It is widely used in many fields such as chemical industry, food preservation, artificial environment, biomedicine, low-temperature superconductivity and aerospace technology. [0003] In the process of food preservation, food refrigerators are often used, but the current refrigerators still have a large number of problems, such as when the door of the refrigerator is opened, a large amount of cold air will escape, causing the problem of air leakage. The internal cooling effect of the refrigerator is not good, and the cold air is easy to leak on the box board, such as the patent 201711156381.2, which only increases the humi...
