First cooling operation step during the installation of the cold room
The first step is to make use of the pressure difference to charge nitrogen
The second step would be to supply the evaporator with the right amount of liquid
The third step will go through a slow cooling operation
The fourth step will be the operation of extreme cooling, at this point you need to verify the effect of cooling.
The cooling effect of the general freezing room is relatively good. Within a limited period of time, we can find that both the evaporation temperature and the temperature in the storage room can rapidly drop to the normal range, and the cooling rate can also meet the requirements. The natural heating in the warehouse is also normal, and after the slow cooling, the wall of the warehouse is generally relatively dry, there will be no cracks or deformation of the situation.
When the low-temperature cold storage is installed, if the first temperature reduction debugging can be carried out, the civil structure can also play a certain guarantee, so as to avoid the sudden decrease of the temperature and the failure of the civil structure.
