The condenser, as explained by the Chongqing Refrigerated Truck editor, is one of the main heat exchange devices in a refrigeration system. Its function is to cool the high-temperature, superheated refrigerant vapor discharged from the compressor into a normal-pressure, normal-temperature refrigerant liquid. Commonly used condensers are classified into three types according to their cooling medium and cooling method: water-cooled (which can be further divided into shell-and-tube, coaxial, and immersion types), air-cooled (or air-cooled), and evaporative (the refrigerant condenses inside the tubes, while being cooled by both water and air spray outside). Obviously, different types of condensers result in different energy consumption for the water pump and fan, and also varying condensing pressures, thus affecting the power consumption and cooling capacity of the compressor's compression process. Therefore, the correct selection and configuration of the condenser should be given due attention.

Air-cooled condensers, due to their poor cooling effect and high condensing temperature, are mainly used in locations lacking cooling water sources, decentralized systems, and small-scale refrigeration systems. In the past, large and medium-sized refrigeration systems mostly used vertical or horizontal shell and tube condensers. In order to reduce cooling water consumption, they mostly used circulating water, so cooling water towers or cooling water pools were required. This resulted in the disadvantages of large footprint of condenser and cooling tower equipment and high power consumption of circulating water pumps and cooling water tower fans.
