Heat Exchanger for Central Air Conditioning Indoor Units

The design of heat exchangers for central air-conditioning indoor units takes into account a number of aspects:

Material selection: Copper tubes are widely used because of their good thermal conductivity and corrosion resistance, while aluminium fins are widely used because of their light weight and good thermal conductivity.

Layout of piping: Reasonable piping arrangement can improve the flow of refrigerant and heat exchange efficiency. Common layouts are U-shape, Z-shape and so on.

Fin design: the shape, thickness and spacing of fins will affect the air flow and heat exchange efficiency. different shapes of fins such as G-type and L-type can optimise the air flow.

Surface area: Increasing the surface area of the heat exchanger can improve heat exchange efficiency, but volume and weight limitations should also be taken into account.

Air flow: The design should ensure that the air can flow evenly through the heat exchanger, reducing dead zones and airflow resistance and improving efficiency.

Ease of maintenance: Heat exchangers should be designed for easy cleaning and maintenance to extend the life of the equipment.
