Design conditions greenhouse accessories manufacturer 1. industrial cryogenic equipment insulation condition is stable. Chiller thermal loads only (the object to be cooled heat and indoor heating appliances included) consists of two parts into the system from the outside heat and cold with the heat inside the device and can not be considered completely cold and refrigeration equipment heat capacity of the machine structure, and thus relatively easy to determine. The main working conditions and low environmental testing equipment non stable variable temperature conditions. In the cooling process, in addition to the aforementioned source, the low temperature chamber for thermal insulation structure and chiller systems in pipe fittings and other low-ju conditions of heat release, not only must be considered, and in fact often greater than the sum of other thermal loads, become Thermal load mainly faction. Cooling process heat load calculation to save, is a non-steady heat conduction and heat transfer problems, the structure of its value not only with low greenhouse, materials related to, and the ability of the refrigerator, working conditions, and low indoor air, the specimen size, structure, materials and require a drop disheartened time series of factors have a great relationship. Therefore, the cooling process heat load calculation is a complex issue, there is no one more mature, accurate and reliable, recognized calculation methods. Method to introduce the following, is an engineering approximation. The idea is: to avoid the complex set of non-ancestral thermal problem, taking full account of the process of falling ju ju lower chamber structure and system piping accessories exothermic premise, to make certain simplifying assumptions in order to estimate the steady-state heat transfer theory cooling system during thermal load.
