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 ice making unit, so we must control this heat exchange temperature difference not to 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℃. Generally, air-cooled condensers are not recommended 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.
The higher the ambient temperature, the lower the heat dissipation efficiency of the air-cooled condenser, and the worse the refrigeration efficiency of the ice maker. The temperature limit of the air-cooled condenser is not higher than 50℃ and not lower than 20℃. Generally, air-cooled condensers are not recommended in areas where the ambient temperature exceeds 38°C. Therefore, whether to choose an air-cooled condenser, first confirm the ambient temperature.
