How to build a fruit freezer

The method for manufacturing the fruit refrigerator is as follows:

1, as far as possible to reduce the electricity consumption of cold storage, to save electricity consumption, it is necessary to reduce the unit heat flow of cold storage envelope:

1) The thermal conductivity of thermal insulation materials should be small;

2) The envelope layer should be thick. But the thickness should not be too thick, otherwise there will be problems such as increasing construction cost and wasting space. 3) In order to reduce the absorption of solar radiation energy, the outer wall surface of cold storage is generally painted with white or light color.

4) The building of fruit cold storage should prevent the diffusion of water vapor and the infiltration of air.

2. Requirements for moisture-proof and heat-insulating materials: vapor permeation has high resistance, low density, good toughness and convenient construction, so as to ensure the construction quality. Other requirements are the same as thermal insulation materials.

3. The moisture-proof and vapor-proof materials commonly used in cold storage are: petroleum asphalt linoleum, petroleum asphalt, one felt with two oils, two felt with three oils, polyethylene plastic film, glass fiber reinforced plastic, etc.
