The Principle and Maintenance of Air-Cooled 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? What are the advantages and disadvantages of air cooling and water cooling? Today, industrial flake ice machine supplierscome to tell you about air-cooled flake ice machines.

Air-cooled condenser

As the name implies, the air-cooled flake ice machine uses an air-cooled condenser.

Cooling performance:

Determined by the ambient temperature, the higher the ambient temperature, the higher the condensation temperature. Generally, an air-cooled condenser is used, and the condensation temperature is 7 ~ 12 ℃ higher than the ambient temperature. The value of 7 ~ 12 ℃ is called the heat exchange temperature difference. The higher the condensation temperature, the lower the refrigeration efficiency of the refrigeration unit, so we have to control this heat exchange temperature difference should not be too large. However, if the temperature difference of the heat exchange is too small, the heat exchange area and the circulating air volume of the air-cooled condenser will 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 ℃. Generally, air-cooled condensers are not recommended in areas where the ambient temperature exceeds 42 ° C. Therefore, whether to choose an air-cooled condenser, we must first confirm the ambient temperature. Generally, when designing an air-cooled flake ice machine, the customer must be asked to provide the highest 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 water resources required, low operating costs.

2. It is easy to install and use, no other supporting equipment is required, as long as it is connected to the power supply, it can be put into operation without polluting the environment.

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

Disadvantages:

1. Higher cost input.

2. The higher condensation temperature reduces the operating efficiency of the refrigeration unit.

3. It is not suitable for areas with dirty air and dusty climate.
