What is the working principle and function of an air heat exchanger?

In the drying and ventilation heating systems of factories, air heat exchangers are essential and important components. The air heat exchanger is composed of heat dissipation pipes, inlet and outlet pipes, pipeline frames, and other parts. It exchanges fresh outdoor air with indoor turbid gas through a circulation system and expels the outdoor air. Although air heat exchanger is an environmentally friendly high-tech product, its internal working principle is relatively simple. Below, the editor will introduce the working principle and function of air heat exchanger.

Working principle of air heat exchanger

The main body of an air heat exchanger consists of three main parts: a heat exchange core, an indoor side fan, and an outdoor side fan. It also includes metal protective shells and accessories such as air supply pipes. The internal part of the heat exchanger is made of 100 flat and thin aluminum plates, with a single aluminum plate area of 495 × 495 (mm2), with a total heat exchange area of 495 × four hundred and ninety-five × 98 (mm2). The heat exchanger is externally wrapped in a metal shell. Seal the interface and joints with sealant. The air inlet sections on both sides of the heat exchanger are equipped with static pressure boxes. Both sides are equipped with axial flow fans, model JH315B, rated voltage 240V, rated air volume 1680m3/h, and rated power 303W.

The air heat exchanger utilizes the indoor and outdoor temperature difference to exchange heat between the gases on both sides, thereby reducing the indoor temperature, as shown in the figure. From the perspective of the outdoor side, outdoor air enters the device body through the outdoor air supply outlet under the action of the outdoor fan, and then exchanges heat through the heat exchange core. From the outdoor side exhaust outlet, it is discharged to the outdoor; From the perspective of the indoor side, indoor air enters the device body through the indoor side supply duct under the action of the indoor side fan, and then exchanges heat through the heat exchange core, and then returns to the machine room through the indoor side return duct.

The role of air heat exchangers

A water to air heat exchanger is a system that has two components that are heated into the air and cooled by the temperature of the water in the system. As a transfer device in these systems, as long as the allowed temperature of water is heated or cooled, air is then forced through the fan. The changes in this system can be found in various fields. Sometimes, this system is used for heating and cooling in homes. Another example is a car's air conditioning system, which is transferred to cooled air through the engine's coolant circulation and then blown out through ventilation holes.

The water in an air heat exchanger typically passes through a coil system using water or other liquids. On the contrary, regardless of the temperature of the coil, it is usually transferred to the external air by the device's sensing system, which allows it to be transferred to a collection area. Then, it can be forced to exit the surrounding temperature of the coil in the system into the environment through a fan.

These systems can be used to heat or cool the temperature of the air, as they are dispersed and directly related to the temperature of the fluid through the operation of the coil. For example, a unit has the ability to heat two units, and a household's car is heated and cooled in the same way. Using such a system allows homeowners to purchase a system and use its air conditioning unit and heater. This method is more cost-effective than purchasing and installing a separate furnace. It is also more environmentally friendly in the long run, let alone safer. Having a huge furnace with a roaring open fire in the basement is not necessarily the safest choice for homeowners, making them vulnerable to fires, carbon monoxide, and even explosions. The use of heat exchangers can change the safety of homeowners in this situation while saving extra money.

In short, an air heat exchanger is a machine with a lower price, compact structure, good heat dissipation performance, good air tightness, advanced technology, and very easy installation and use. In addition, the maintenance work of the air heat exchanger is also very simple, as it is made of steel aluminum composite material, which has high thermal resistance, sturdy machine, and high temperature resistance.
