Cold storage budget calculation
Cold storage budget is how to do, how to do a good job in the cold storagebudget, how is the reasonable cold storage budget, which is a lot of peoplewant cold storage building, are very concerned about the problem, want toknow whether they are ready now, Theil refrigeration Xiaobian detailed solution for you.
Cold storage budget according to the materials and equipment and the use ofcold storage area built to calculate.
First calculate the refrigerator building materials, cold storage building when the cold plate, is the construction of cold storage must, more plate area is greater use, relative budget will increasingly high, plate selection is also veryimportant, polyurethane cold plate as far as possible the use of green environmental protection.
Polyurethane cold plate has a moisture-proof, waterproof performance. Closed cell polyurethane at a rate above 90%, belongs to the hydrophobic material,not due to moisture absorption thermal conductivity increases, the wall also not seepage. Hard polyurethane flame-retardant, flame retardant, high temperature resistant. Polyurethane in the flame retardant agent, a nonflammable self extinguishing materials, softening point it can reach 250degrees Celsius, only at higher temperature will appear when thedecomposition: in addition, polyurethane will carbon formation in the bubblesurface in combustion, the laminated carbon help isolation following bubble.Can effectively prevent the spread of flame. Moreover, polyurethane at high temperature does not produce harmful gases.
Cold storage building without refrigeration equipment, refrigeration equipmentchoices affect the cold storage cost, good equipment relative price is high, but the quality will be relatively better. The greater the refrigeration unit cold storage needed will increase, at the same time, the price will rise. China online selection for cold storage refrigeration equipment to analyze.
General cold storage by the refrigerating systems, using the gasificationtemperature is very low (or liquid ammonia Freon) as coolant, the evaporationat low pressure and mechanical control conditions, absorption of heat in therepository, so as to achieve the purpose of cooling. The most commonly used is the compression type refrigerating machine, mainly composed of a compressor, condenser, throttle valve and the evaporation tube. According to the evaporation tube device mode can be divided into direct cooling and indirect cooling of two. Direct cooling of the evaporating pipe installed in therefrigerated warehouse, liquid coolant through the throttle valve, the direct absorption of heat and cool warehouse. Indirect cooling is composed of ablower will take in air cooling device for pumping the air inside the warehouse,the heat absorption tube is hovering in the air cooling device of evaporated,send into the storage and cooling. Advantages of air cooling mode is coolingrapidly, inside temperature is uniform, and can be produced in the process of storage carbon dioxide and other harmful gases with out outside.
