What does pressure equalization do?
What does a pressure equalization valve do? The refrigerators in our homes will explain this more simply. Let's try it.
When we open and close the door of the -18 compartment of the refrigerator in our home, this door will be difficult to open.
The meaning of this experiment is that the cooled environment creates a vacuum and draws in hot air.
In this case, -18°C will cause the same problem for the cold room. In rooms where pressure equalization valves are not installed, panels have been observed warping inward. Even rooms have exploded.
The benefit of the pressure balancing valve here is to equalize the air values between the inside of the cold room and the outside environment, dry the air it takes in, eliminate its moisture and then take the air in.
In cold storage environments where pressure balancing and walfi are not installed, the humid air that enters every time the door is opened will cause excessive icing in the evaporator, interrupting the cooling and causing the products to spoil.
Let's see the benefits of the pressure balancing valve.
