It is determined by the ambient temperature that the higher the ambient temperature, the higher the condensation temperature. Generally, an air-cooled condenser is used, and the condensation temperature is 7 to 12 ° C higher than the ambient temperature. The value of 7 to 12 ° C is called the heat exchange temperature difference. The higher the condensation temperature, the lower the refrigeration efficiency of the refrigeration unit, so we must control the 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 of the air-cooled condenser and the circulating air volume will be larger, and the cost of the air-cooled condenser will be higher.

The temperature limit is not higher than 55 ° C, not lower than 20 ° C. Air-cooled condensers are not recommended in areas where ambient temperatures exceed 42 °C. So whether you can choose an air-cooled condenser, first confirm the ambient temperature. When designing an air-cooled ice machine in general, customers must be required to provide the highest ambient dry bulb temperature in the country.
