The condenser is the heat exchanger by which the heat of the refrigerating system is rejected.
This is the heat absorbed in the evaporator plus the heat corresponding to the work supplied by the motor to the compressor.
By withdrawing heat from the refrigerant fluid from the discharge of the compressor, with high temperature and high pressure, condensation of that refrigerant fluid is caused, keeping the refrigerant fluid cycle closed. The condenser rejects heat to a cooling medium, which absorbs this heat.
In industrial refrigeration the most common condenser cooling media are air and water.
Depending on the cooling medium used, the capacitors are classified as:
• water-cooled
• air-cooled
• evaporative
Air-cooled condensers are poorly used in industrial refrigeration due to high condensing temperatures.
Given only this aspect, the most interesting condenser is the evaporative condenser and the water cooled. The use of lost water is discarded because it is not advisable for economic or ecological reasons.
