1. The conventional design temperature of laboratory cold storage:
The design environment temperature of laboratory refrigerated storage is 2~8 C;
The design environment temperature of laboratory freezer is -20~-25 C;
Laboratory Cryogenic reservoir Design environment temperature: -30 C ~-80 C
The above 3 are the design temperatures of common laboratory refrigeratory.
Two. Acceptance criteria for laboratory refrigeratory:
The standard for laboratory acceptance of cold storage is mainly in accordance with the industry.
If it is a cryogenic Laboratory for the food industry, on the construction plan, the owner can make specific customized plans according to his own budget and requirements.
If it is in the medical and other important research projects, the best way to build the cryogenic laboratory is to choose alternate schemes in terms of refrigeration system, power supply, fault system and so on.
This is high in terms of construction cost, especially in the ultra low temperature reserve unit of -30 C ~-80 C, and 50%-80% should be mentioned more in the construction budget.
Three, the laboratory cold storage -30 degrees ~-80 centigrade customization focuses on:
The cold storage room at -30 C ~-80 degrees C:
1, thermal insulation board: 30cm~40cm polyurethane single sided stainless steel plate or double-sided color steel is recommended. Conventional 10 feet m, 12cm, 15cm and 20cm have been unable to meet such low temperature thermal conductivity requirements.
2, refrigeration equipment: for a temperature refrigeration compressor with a temperature of less than -30 degrees, single stage vortex and piston have been unable to meet such low temperature environmental conditions. It is necessary to use bipolar compressor or cascade compressor unit to make refrigeration system.
3, temperature and humidity detection: because the laboratory is a low-temperature storeroom, so the accurate control of temperature in scientific research work and the reduction of the error value can not be ignored.
Four, laboratory cold storage -30 centigrade ~-80 C custom price accounting:
The custom-made price of the laboratory freezer is the same as the custom-made price accounting method of our regular refrigeratory.
According to the size of customized insulation board, according to the number of thermal insulation materials, the total cost of thermal insulation materials;
According to the laboratory refrigeratory -30 C ~-80 C, the capacity of the bipolar unit or the cascade equipment with suitable refrigerating capacity and the evaporator of the same cold amount are allocated, and the amount and price of the material appendages of the equipment are accumulated.
Besides, the accumulated materials are: frozen oil, refrigerant, valve, electric control box, temperature and humidity recording equipment, pipeline and so on.
Therefore, in the premise of knowing the temperature, we should know the volume and specific equipment related grade requirements, in order to give a reasonable plan and cost.
