CBFI industrial ice making machine is divided into air-cooled ice maker machine and water cooled ice maker machine. Today we know the

advantages and disadvantages of air-cooled ice maker.

advantage of air cooled ice machine

1. No need of water resources, lower operating cost.

2. Easy to install and use, no other supporting equipment is needed, it can be put into operation as long as the power is turned on

3. Does not pollute the environment.

4. It is suitable for areas with severe water shortage or rare water supply.

shortcoming of air cooled ice maker

1. Higher cost investment.

2. The high condensing temperature reduces the operating efficiency of the refrigeration unit.

3. Not suitable for areas with dirty air and dusty climate.

Cooling performance

It is determined by the ambient wet bulb temperature. The higher the ambient wet bulb temperature, the higher the condensation temperature. Generally, a water-cooled condenser is used, and the condensing temperature is about 5 to 7°C higher than the ambient wet bulb temperature.

Temperature limit

Not higher than 55°C, not lower than 20°C. Under normal circumstances, it is not recommended to use water-cooled condensers in areas where the ambient wet bulb temperature exceeds 42°C. Therefore, whether to choose a water-cooled condenser, first confirm the ambient wet bulb temperature.

Generally, when designing a water-cooled ice maker, the customer must be required to provide the highest ambient wet bulb temperature throughout the year in the local area. At the same time, when the ambient temperature exceeds 50 ℃, the condenser cannot be cooled with water, and the cooling tower is easily damaged by the high temperature. The cooling tower must be used under sun protection.

Air-cooled ice making maker

Determined by the ambient temperature, the higher the ambient temperature, the higher the condensation temperature. Generally, an air-cooled condenser is used, and the condensing temperature is 7-12°C higher than the ambient temperature. This value of 7-12°C is called the heat exchange temperature difference. The higher the condensing temperature, the lower the refrigeration efficiency of the refrigeration unit, so we must control this heat exchange temperature difference should not be too large. However, if the temperature difference of heat exchange is to be too small, the heat exchange area of the air-cooled condenser and the circulating air volume must be larger, and the cost of the air-cooled condenser will be higher.

The temperature limit is not higher than 55℃ and not lower than 20℃. Under normal circumstances, it is not recommended to use air-cooled condensers in areas where the ambient temperature exceeds 42°C. Therefore, whether to choose an air-cooled condenser, first confirm the ambient temperature. Generally, when designing an air-cooled ice machine, the customer must be required to provide the highest ambient dry bulb temperature throughout the year in the local area.

The higher the ambient temperature, the lower the heat dissipation efficiency of the air-cooled condenser and the worse the cooling efficiency. The temperature limit of the air-cooled condenser is not higher than 50°C and not lower than 20°C. Under normal circumstances, it is not recommended to use air-cooled condensers in areas where the ambient temperature exceeds 38°C. Therefore, whether to choose an air-cooled condenser, first confirm the ambient temperature.
