Face-to-face blowing type double-circulation air curtain unit

Abstract

The invention provides a face-to-face blowing type double-circulation air curtain unit, and belongs to the technical field of refrigeration houses. The face-to-face blowing type double-circulation aircurtain unit comprises a first case and a second case which are oppositely arranged. A first fan and a third fan are arranged on the first case. A first opening communicating with an inner cavity ofthe first case is formed in the first case. A second fan is arranged on the second case. A second opening and a third opening which communicate with an inner cavity of the second case are formed in the second case. The first fan is opposite to the second opening. The second fan is opposite to the first opening. The third fan is opposite to the third opening. According to the face-to-face blowing type double-circulation air curtain unit, double circulation of air flow can be achieved, cyclically-flowing air can better prevent cold air in a refrigeration house from flowing out and prevent hot air outside the refrigeration house from entering the refrigeration house, and a better blocking effect is achieved; and the face-to-face blowing type double-circulation air curtain unit has a better heat insulation effect and can save more energy.

Description

technical field [0001] The invention belongs to the technical field of cold storage, and relates to a blowing-type double-circulation air curtain unit. Background technique [0002] With the development of the food industry, there are more and more types of food, and some food will be stored in low-temperature freezing, so cold storage will be built, and cold storage doors are widely used in cold storage. When the cold storage door is opened, in order to block the outflow of cold air in the cold storage, an air curtain machine is often used. [0003] In the prior art, only one air curtain machine is installed on the door of the cold storage, and the gas is blown from top to bottom through the air curtain machine, so as to prevent the cold air from flowing out of the cold storage. [0004] The above-mentioned air curtain machine has a limited blocking effect on the cold air, and the blocking effect is poor. There will be frosting at the door of the cold storage. The reason i...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned air curtain machine has a limited blocking effect on the cold air, and the blocking effect is poor. There will be frost at the door of the cold storage. The reason is that the cold air sinks and the hot air rises.

In addition, the traditional air curtain machine has the weakest effect of blocking cold air when the cold storage door is close to the ground, so this position is the position where the cold air outflow is strongest
