Condensing Units – Classification and Usage!

Condensing units are temperature control devices that are used in refrigerators, air conditioners, heat pumps as well as chillers. These units help in moving energy in the heat form by compressing a gas called refrigerant vapor. Then it pumps the vapor through a system of coils and making use of the surrounding air around the coils to heat and cool spaces.

The condenser coils are located along with the compressor and controlling devices within the condensing units. Condensing units are available in a wide range of sizes from small ones used in office fountains to huge ones used in air condition buildings like the Pentagon. Also, these units vary in designs such as plain tube, plate type or parallel pass units and more.

Classification of Condensing Units

Condensing units can be classified as per their cooling method as well. The three main types include air-cooled, combined air and water cooled and water cooled condensing units.

  • Air-Cooled Condensing Units

Air cooled condensing units comprises a coil of ample surface so that air can be blown by a fan or induced by natural draft. Such units are usually used in small capacity refrigerating units such as residential air conditioners or air conditioning system of small offices. To keep these units working in the their best condition, these should be kept free from dust, dirt, lint and other foreign elements as accumulation of these particles may reduce the airflow around the tubes and fins.

  • Combined Air- and Water-cooled Condensing Units

Also, referred as evaporative condensing units, the combined ones consist of a coil that is cooled by spraying water from above and then allowing the cold air to enter from the bottom and blow across the coils. When the water evaporates from the coils a cooling effect is being induced that condenses the refrigerant within the coil. The hot refrigerant gas in the coil is then changed to the liquid state by combining the sprayed water and large column of moving air supplied by the fan. And the remaining water that does not get evaporated gets recirculated with the help of a pump.

  • Water-Cooled Condensing Units

Water cooled condensing units as names suggest are cooled using water alone. The water circulates through the tubes and coils within the unit enclosed in a shell. In these units the refrigerant moves through the annular space between the tubes or the coils. These condensing units are also termed as double pipe condenser based on its construction. These condensing units are eco-friendly options as well as eliminate the water disposal problems which further make it an economical means of cooling refrigerant gases.
