Air-cooled evaporators are special heat exchangers for cooling the air mass in chillers or cold rooms. They differ in power, construction, and use of refrigerants. Even the capacity of the same model can vary depending on the boiling point of the refrigerant and the boiling delta (the difference between the boiling point and the temperature in the refrigerating chamber), the used refrigerant, the speed of the fans.
There are different types of evaporators, like cooler evaporator and shell and tube type evaporator. Therefore, before you buy air-cooled chillers, you need to consider the operating conditions. Commercial and industrial refrigeration evaporators are differentiated depending on the capacity and the application area. They have a relatively small capacity (up to 10-15 kW) and are used in small and medium-sized applications.
And here the condenser must to be mentioned. The AC condenser units are among the main parts of cooling AC systems. It is the outside unit that usually sits on a roof or in a yard. Many issues may affect how an AC condenser works, with all of these problems affecting how the AC system functions.
What Is An Aircon Condenser?
An AC condenser or condenser is an outdoor part of a heat pump or air conditioner that collects or releases heat (depending on the time of the year). Both the heat pump and split-air conditioner condensers feature the same main or basic parts. The condenser cabinet houses a compressor, condenser coil, a fan, and various controls. The condenser coils are either made of all-aluminium tubing, which allows for rapid heat transference, or copper tubing.
Also, condensers can be devided into different types like water cooled condenser, air cooled condenser, condensing unit, Water Cooled Condensing Unit, air cooled condensing unit, etc.
What Role Does An Aircon Condenser Perform?
The condenser in an AC system receives high-pressure gas from a compressor, converting the gas into a liquid. This is made possible by heat transfer, which relies on a principle whereby heat will move from warmer to cooler substances.
When the refrigerant starts flowing through a condenser, the fins in the condenser allow heat transference to the “surrounding air”. The condenser also features a fan over the top that makes sure the heated air is cooled off quickly, enabling these processes to continue. Once the refrigerant temperature drops below its “saturation temperature”, it will turn back into a liquid. However, it needs to work with other refrigeration spare parts as well.
