VIP mainly used for thermal insulation, such as home refrigerator, yacht refrigerator, mini fridge, car refrigerator cryogenic freezers, electric water heater, vending machines, freezers, cold storage container, building wall insulation and LNG storage and transportation.VIP in refrigeration equipment in the application.A.. Refrigerator using VIP heat insulation, can save 10% - 30%, and increase the effective volume of 20% - 30%. Tight tube now in the VIP price is also high, but users use the refrigerator 7-10 years to save electricity, has a considerable in the refrigerator by VIP insulation increased costs. The VIP heat insulation, in addition to the economic significance of fridge weight Light, the advantages of small volume. The refrigerator door and the refrigerator door, light, thin wall, the VIP heat insulation has great technical and economic significance. B. to store cold materials to maintain low temperature refrigerated box: with PU or PF insulation, heat preservation period of only 1-2 days; the VIP heat insulation materials, heat preservation period extended to 4-5 days, make the original must be airlifted items can use trucks or rail, greatly reduce the transportation cost. Refrigerated and insulated box, installed insulation for the same items under 1. PU foam, dimensions 57cmx50cmx50cm insulation layer thickness 3.8c M, the inner mounted coolant 21.8KG and 120h insulation; 2. Use the VIP heat insulation dimensions in the 33cmx46cmx28cm, insulation box volume reduced by 70%, the coolant reduced by 68%, and heat preservation period was extended to 66%. Reduce transportation cost, improve the distance, and the economic effects are obvious.
