What Are The Condensation Methods Of The Flake Ice Machine

What are the condensation methods of the flake ice machine

From the market point of view, the condensation methods of flake ice machines are roughly divided into two types: air cooling and water cooling. But what is the difference between air cooling and water cooling, and what are the advantages and disadvantages of air cooling and water cooling? I think there may be some customers who do not understand enough. Today I will tell you the difference between air cooling and water cooling.

The air-cooled flake ice machine uses a general air-cooled condenser. With an air-cooled condenser, the condensation temperature is 7~12°C higher than the ambient temperature. The value of 7~12°C is called the heat transfer temperature difference. The higher the condensing temperature, the lower the cooling efficiency of the refrigeration unit, so we must control the heat transfer temperature difference so that it should not be too large. However, if the temperature difference of the heat exchange is to be too small, the larger the heat exchange area of the air-cooled condenser and the circulating air volume, the higher the cost of the air-cooled condenser. The temperature limit is not higher than 55°C and not lower than 20°C. Generally, air-cooled condensers are not recommended in areas where the ambient temperature exceeds 42°C. So whether you can choose an air-cooled condenser, you must first confirm the ambient temperature. Generally, when designing an air-cooled flake ice machine, the customer must be required to provide the highest local ambient dry bulb temperature throughout the year. Air-cooled condensers cannot be used in areas where the ambient temperature exceeds 40°C.

advantage:
1. No need for water resources, low operating cost.
2. It is easy to install and use, no other supporting equipment is needed, and it can be put into operation as long as the power is connected, without polluting the environment.
3. It is suitable for areas with severe water shortage or rare water supply.
shortcoming:
1. High cost input.
2. The high condensation temperature reduces the operating efficiency of the refrigeration unit.
3. It is not suitable for areas with dirty air and dusty climate.

The water-cooled flake ice machine uses a water-cooled condenser

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 condensation temperature is about 5~7°C higher than the ambient wet bulb temperature.
temperature limit
Not higher than 55°C, not lower than 20°C. Generally, water-cooled condensers are not recommended in areas where the ambient wet bulb temperature exceeds 42°C. So whether you can choose a water-cooled condenser, you must first confirm the ambient wet bulb temperature.
Generally, when designing a water-cooled flake ice machine, the customer must be required to provide the highest local ambient wet bulb temperature throughout the year. At the same time, when the ambient wet bulb temperature exceeds 50°C, the condenser cannot be cooled with water, and the cooling tower is easily damaged by the high temperature. Cooling towers must be used with sun protection.
