20℃-42℃ Most Suitable Environment Temperature for Air-cooled Condenser for Ice Machine

         Under normal circumstances, the ambient temperature exceeds 42 ℃ is not recommended in areas with air-cooled condenser. The most suitable environment temperature is 20-42 ℃.So whether optional air-cooled condenser, first make sure the ambient temperature. General design air-cooled ice machine, you must require customers to provide the highest annual local environmental dry bulb temperature.
     Determined by the ambient temperature, the higher the temperature, the higher the condensation temperature. In general, the use of air-cooled condenser, condensing temperature higher than the ambient temperature 7 ~ 12 ℃, 7 ~ 12 ℃ temperature difference we call this value. Condensing temperature higher cooling efficiency refrigeration unit will be lower, so we have to control the temperature difference should not be too large. But if you want the heat exchanger temperature difference is too small, then the amount of wind-cooled condenser heat transfer area and the cycle would the greater cost of the higher cost of air-cooled condenser.
 
     We  ice block machine has three condensing methods :air-cooled condenser,water-cooled condenser and evaporation condenser.I will tell you the first one about its advantages and disvantages:
      The Advantage :
      1.Without water resources, lower operating costs.
      2. Install, easy to use, no other ancillary equipment, as long as the power supply can be put into operation
      3.Do not pollute the environment.
     For severe water shortages or water rare regions.
     The Shortcoming
     1.High cost of inputs.
     2.Condensing temperature is higher, so that the efficiency of the refrigeration unit is reduced.
     3.Does not apply to air pollution, there is dust climates.
