Rumantcev U.D. , Veselkin F.O.
One of the main goals of modern refrigeration industry is to reduce energy costs, increase the quality of storage and transportation of perishable goods. Particular attention is paid to refrigerated transport, such as refrigerated trucks, which impose stringent requirements on the safety of perishable foods and maintaining energy efficiency, which is caused by correct selection of refrigeration equipment, during the entire period of operation. In this work will detail the basic methods of calculation of the thermal load and the determination of the coefficient of heat transfer, what requirements they are controlled, and that was made of the new, by years of experience and multiple testing of refrigeration equipment under different operating conditions. Made additional parameters that take into account processes such as multiple door openings of the body, changing the properties of the heat-insulated surface because of the "aging" of the car body. The examples, which you can clearly see the dependence of the thermal load on the volume, "aging" heat-insulated body surfaces, the number of door openings and the degree of loading of the car.
