Problems To Be Considered In Installation Design Of Deep Freezer Cold Room

Refrigerating Compressor Energy Regulation: As Cuvin drops, the refrigerating capacity required for the cryogenic deep freezer cold room will also decrease. The compressor installed with energy regulation can adjust the energy output of the compressor according to the change of load, it reduces power consumption.

2. Frequency conversion control of refrigeration compressor motor

3. Temperature performance consideration: the thermal insulation material of deep cold storage is the heat transfer speed of blocking temperature, not absolute non-heat transfer, so the density of thermal insulation material and the structure of thermal insulation material are the key to blocking temperature, thermal insulation heat transfer is slow, is equal to the cold loss slow, then the compressor working time is relatively short, relative power consumption is also less. Therefore, it is suggested to use closed-end foaming polyurethane as the insulation board of the cold storage, so as to play a more insulation effect.

4. The choice of condenser and condensing pressure control in cold storage:

(1)The height of condensing temperature has a direct influence on the power consumption of the compressor. In the design of the cold room of the deep cold storage, the appropriate condensers should be selected according to the specific conditions of the cold storage.

(2)The condensing pressure changes with the change of ambient temperature, so according to the change of ambient temperature to adjust the number of condenser motor opening, can reduce the power consumption of cold storage.

It is necessary to pay attention to energy-saving in the construction of cold room of deep cold storage, adopt energy-saving design and refrigeration equipment with high energy-saving. IEMC integrated energy management system can be used to save energy and reduce consumption in high-end deep freezer cold room. On the environmental protection of deep freezer cold room in deep cold storage. Freon refrigerants, which have been phased out in the air-conditioning industry, are still used in some small cold stores, causing serious damage to the environment and not in line with the national development goal of energy conservation and emission reduction, developed Countries in Europe and the United States have been vigorously in the application of CO2 as the representative of the environmental refrigerant. In the future, the construction of cold storage in China should promote the application of environment-friendly refrigerants in order to realize the synchronous development of economic and social benefits.
