The residual air in the refrigeration system can cause a lot of harm, so how does the air get into the refrigeration system? The main approaches are as follows: 1. Before charging the refrigerant, the vacuuming operation is not thoroughly carried out, so that the air remains in the system.2. When th   Read More>

We can judge whether the condenser works normally by checking the temperature difference between the condenser and the cooling medium.For water-cooled condenser, the condensation temperature is about 4~6℃ higher than the outlet temperature of cooling water;For evaporative condenser, the condensation   Read More>

The temperature controller shows the cold room temperature, and the low pressure gauge corresponds to the evaporation temperatureFor the cold room with static evaporator, the air in the cold room is in a state of natural convection, and the evaporation temperature is required to be 10~15℃ lower than   Read More>

Sometimes customers will say, their cold room operated for a while and the cooling effect is not good, the temperature can not come down and so on, all kinds of circumstances, affect the effect of cold room refrigeration factors have aspects. 1. From the perspective of condenser:If it is an air-cool   Read More>

1. Check the refrigeration system, air conditioning system, humidification system, etc.We should find fault maintenance in time, and a few days before fruit and vegetable warehousing, open the refrigeration system to cool the cold room gradient, to meet the storage requirements of temperature.2.

1. The cold room is built of heat insulation material, is afraid of water, afraid of tide, afraid of heat, afraid of running cold and other characteristics, so the wall, the ground, the door, the top of the cold room shall not have ice, frost, water, have to be removed in time. 2. The exhaust pipe a   Read More>

During the operation of cold room, some problems need to be paid attention to:1. To prevent frostbiteWhen entering the cold room, the operation personnel must take heat preservation measures to minimize the exposed parts of the body. The exposed parts must not be in direct contact with goods, pipes,   Read More>

Customers usually ask this question, can I build this cold room as both frozen cold room and fresh cold room, or as both quick-freeze cold room and frozen cold room? Although quick-freeze cold room, frozen cold room and fresh cold room are all cold rooms, but in the use of performance and design the   Read More>

The way to deal with “cold bridge” in cold room is: because the outer surface of the cold room panel is metal, the thermal conductivity is good, so in the construction, the metal between the different temperature of the cold room or the storage outside cold room shall not be directly connected.
