Cold room systems

Cold room systems are basic facilities for cold storage in commercial and industrial food business, pharmaceutical field, seafood business, poultry business and some other fields. Some users know little the correct operation of cold storage room, so sometimes it will cause high power consumption, sometimes it has potentially dangerous. How to operate cold room systems correctly is very important for cold room users, it can extend its lifetime and guarantee its safety if you use or operate cold room systems correctly. The followed are some suggestions on how to operate cold room systems correctly and how to keep routine cold room maintenance. We hope these suggestions are helpful for you!
1. How to use the doors of cold room systems properly?

In order to prevent the damage of cold room doors, please open or close doors lightly.

In order to prevent the leakage of cold air, please kindly close the cold room doors quickly. If we open the cold room doors for a long time, outside hot air will enter inside of room, caused severe frost of fins, then it will have bad cooling effect.




2. How to display products properly in the cold room systems?

When we display goods in cold rooms, don’t block the suction or exhaustion port of the evaporator, please keep the suction or exhaustion port be always open, and distribute the cooling air evenly. In order to make cold air distributed well, the left, right, up and down of the goods should be 5cm distance from each other.

We often see that the suction inlet is blocked by the goods, which will reduce the intake of cold air, resulting in decrease of cooling capacity and damage of the goods.



3. Don’t put goods on top of the cold room ceiling

The ceiling panel of cold rooms is designed as non-load-bearing, and there are some refrigerant piping and electrical wiring layouts. Users are not allowed to stack goods on cold room ceiling panels in order to avoid accidental damages.



4. Keep the condenser be clean and smooth always

Poor ventilation caused high operating temperature, it will shorten the lifetime and increase energy consumption. We should keep condenser fins clean and smooth always.



5.Tips on old room defrosting:

Cold room defrosting is automatic defrosting with electric heating. When the humidity is high in summer, it is easy to freeze for the evaporator, please do not hit ice cubes with hard items, which may cause the leakage of the evaporator coil. The correct method is using warm water to remove ice cubes or increasing defrosting times appropriately



6.Maintenance and repair for the compressor:
The freezing oil level is between the upper and lower limits of the oil monitor, and the oil is not cloudy.
Using liquid sight glass to check the refrigerant charge.
3.Check the compressor oil level.
4. Check the compressor crankcase heater operation.
5. Check the main power supply and control voltage.
6. Check the appearance of the condensing
7. Check the system pressure.
8. Check the cooling system, if it has leakage.
9. Check the suction filter and liquid drying filter.
Check that all bolts, fittings and piping clamps are tight.
Inspect the condenser fan blade paddles and motor assembly for cracks, loose screws, or connection bolts.
12. Check the suction / exhaust / liquid refrigerant pressure and temperature.
13. Check the compressor’scurrent, over-heatdegrees, liquid over-cold degrees and ambient temperature.

1. How to use cold room doors properly?

In order to prevent the damage of cold room doors, please open or close doors lightly.

In order to prevent the leakage of cold air, kindly close the cold room doors quickly. If we open the cold room doors for a long time, outside hot air will enter inside of room, caused severe frost of fins, then it will have bad cooling effect.

2. How to display products properly? Ensure the smooth flow of outlets and suction inlets:

When we display goods in cold rooms, don’t block the suction/exhaust port of the evaporator, keep the suction/exhaustion port be open always, and distribute the cooling evenly. In order to make cold air distributed well, the left, right, up and down of the goods should be 5cm distance each other.

We often see that the suction inlet is blocked by the goods, which will reduce the intake of cold air, resulting in decrease of cooling capacity and damage of the goods.

3. We couldn’t stack goods on top of the cold room ceiling

Cold rooms ceiling panel is designed as non-load-bearing, and there are soem refrigerant piping and electrical wiring layouts, in order to avoid accidental damages, users are not allowed to stack goods on cold room ceiling panels.

4. Keep the condenser be clean and smooth always

Poor ventilation caused high operating temperature, it will shorten the lifetime and increase energy consumption. We should keep condenser fins clean and smooth always.

5. Tips on cold room defrosting:

Cold room defrosting is automatic defrosting with electric heating. When the humidity is high in summer, it is easy to freeze for the evaporator, please do not hit ice cubes with hard items, which may cause the leakage of the evaporator coil. The correct method is using warm water to remove ice cubes or increasing defrosting times appropriately

6. Maintenance and repair for the compressor:

1. The freezing oil level is between the upper and lower limits of the oil monitor, and the oil is not cloudy.
2. Using liquid sight glass to check the refrigerant charge.
3. Check the compressor oil level.
4.  Check the compressor crankcase heater operation.
5.  Check the main power supply and control voltage.
6. Check the appearance of the condensing
7. Check the system pressure.
8.  Check the cooling system, if it has leakage.
9. Check the suction filter and liquid drying filter.
10. Check that all bolts, fittings and piping clamps are tight.
11. Inspect the condenser fan blade paddles and motor assembly for cracks, loose screws, or connection bolts.
12. Check the suction / exhaust / liquid refrigerant pressure and temperature.
13. Check the compressor’scurrent, over-heatdegrees, liquid over-cold degrees and ambient temperature.

Other notes:

1. Temperatureof machine room :

Commonly machine room temperature is below 35 °C, short-term in summer can be below 40 °C. If machine room temperature is too high, it will cause the following problems:

A. If the suction temperature and exhaust temperature increases, the cooling capacity will decrease.

B. The reduction of cooling capacity will increase power consumption and operating cost

2. Pay attention to the equipment inside the room when we display goods.

Normally the capacity of goods incoming does not exceed 20% of the total room capacity. Don’t damage water pipes, refrigerant pipes, etc.

3.Keep cleaning cold room regularly:

Keep cleaning cold rooms regularly can avoid peculiar smell in the room.

Please turn off the power switch when cleaning. Don’t let water immerse into light’s switch, evaporator junction box, etc.
