Condenser can be divided into three categories: water-cooled, air-cooled and evaporative according to its cooling medium.
Water-cooled condenser
Water-cooled condensers use water as a cooling medium and take away the heat of condensation by the temperature difference of water. Cooling water is generally recycled. But the system needs to be equipped with cooling tower or cooling pool. Water-cooled condensers can be divided into shell-and-tube condensers and casing condensers according to their structure.
Air-cooled condenser
Air-cooled condensers use air as a cooling medium and take away the heat of condensation by the temperature rise of the air. This condenser is suitable for occasions where water is extremely scarce or unable to supply water, and is commonly used in small Freon refrigeration units. According to the different air flow, it can be divided into two types: natural convection and forced convection.
Evaporative condenser
The heat exchange of the evaporative condenser is mainly carried out by cooling water evaporating and absorbing the latent heat of vaporization in the air. According to the air flow mode, it can be divided into income type and pressure feed type. As shown, the evaporative condenser is composed of condensing coil, fan, circulating water pump, and water distribution system. The condenser coil can be selected from seamless steel tube, corrugated tube and finned tube.
