Air Heat Exchanger
An air heat exchanger is a device that is used to transfer heat between two air streams. It is commonly used in heating, ventilation, and air conditioning (HVAC) systems. The heat exchanger can be designed to allow the two air streams to be either separately or together.
Generally, we classify the air heat exchanger into Finned Tube Heat Exchanger, Plate Type Air Heat Exchanger, Seamless Pipe Air Heat Exchanger, Twisted Heat Exchanger, etc. according to its structure.
Air heat exchangers are commonly used for a variety of applications in the HVAC system, such as space heating, cooling, humidification and air circulation. In space heating applications, air heat exchangers are used to transfer heat from outside air to indoor air, in order to provide heat for the building. In cooling and air circulation applications, air heat exchangers are used to transfer heat from an indoor space to the outside. in order to keep the building cool.
The main advantage of using an air heat exchanger is that it is very efficient in transferring heat energy between the two streams without any loss. It is also relatively inexpensive, compared to other types of heat exchangers. Additionally, air heat exchangers are small and compact, making them ideal for applications in tight spaces.
