Everyone knows that freezer has the performance of heat insulation .Do you know why? Here are the simple examples. First of all, if there is no performance of heat insulation , the inner and outer temperature of the freezer will be the same in a hot summer, freezers, both inside and outside temperature can reach an agreement, so obviously freezer ‘s refrigeration effect can not be reached without . If there is no heat insulation performance, then the hot air from the outside will conduct into the ark, then make the internal temperature of the freezer rise again. The machine works for keeping the temperature low ,while the hot environment will always affect the cabinet .It is not only a kind of energy wasting ,but also nonsense . So adopted the heat insulation performance in order to better realize the ability of freezer. Here is to show the benefits and functions of the material.
Freezer should not only have good heat insulation, the selection of thermal insulation material and the design is very important for the quality of the freezer. The materials must adjust measures to local conditions, it must be economical and practical. There are several types of insulation, one is processed into fixed shape and the plate of in curtain specifications , with a fixed length, width and thickness, can be chosen according to the needs of freezer cabinet.To install the corresponding specification plate, high and medium temperature freezers would generally choose the plate of 10 cm in thickness , low temperature freezer and frozen freezer generally choose the plate of 12 cm or 15 cm in thickness ; Another kind of material-choosing can use polyurethane foaming, the material spray to the brick or concrete warehouse which have been built directly after that process ,it is moisture-proof and insulation. Polyurethane and polystyrene are two kinds of insulation plates .polyurethane has a good insulating performance and it is not bibulous, but in higher cost; While totally different compare with polystyrene.that is all the information about the insulation.
