Cold rooms are commonly used for industrial purposes. Aside from maintenance, owners or operators should also be familiar with the common problems that they might encounter with these temperature-controlled rooms. Here are some of those problems, including their causes and some recommended solutions.
1. The refrigeration function cannot be turned on
- The switch is broken.
- Loose connection from the power source.
- Unsuitable line voltage.
- The circuit breaker is not working.
Check the switch. Try to switch it off first and then turn it back on again. If nothing happens, you can also check if the power cable is properly connected or if it is connected with an appropriate line voltage.
2. Rotting of products
High temperature, particularly products on top shelves.
Products are already rotten, even before storing them.
Always check if the products are damaged or overripe before storing them. If the room has an uneven temperature, the top shelf products will be exposed to warmer temperatures because warmer air travels up. Stack products wisely. Aside from rotting, higher temperatures can also cause early signs of aging, particularly in raw products.
3. Some products are over-freezing and some are not
Freezing air from the evaporator coils is going directly to the product.
Products are stacked too close to the coils.
The products inside are not properly arranged.
Consider installing a restraining device under the coils to deflect cold air. Stack your products in a way that cold air can still spread freely inside the room. It is advisable to stock products in the lower part of the room.
4. Water Build-Up in products
- Warm temperature in the area of the product.
- Warm products are in contact with already frozen products.
- Leaked defrosted water on the product.
Make sure that the defrost drain tubes are not leaking to prevent them from dripping onto the products. Also, consider stacking warm products away from already frozen products. Installing humidification equipment is also recommended.
5. The temperature is warmer than the original temperature
- The refrigeration unit is not sufficient to cope with the volume of stored products.
- Hot weather.
- The airflow is not suitable for the room size.
Install a higher refrigeration cooling capacity and install appropriate (thicker) walling and roofing materials.
