Principle of waste heat recovery technology of air source treatment unit

Posted by Admin

In air source heat pump systems, air conditioning systems or other air handling devices, a large amount of energy is often consumed in order to complete functions such as cooling, heating or ventilation. During the conversion process of these energy sources, part of it will be lost to the environment in the form of heat energy, forming so-called "waste heat". If this waste heat is not utilized, it will become a waste of resources and cause thermal pollution to the environment.
The introduction of waste heat recovery technology in air source treatment units aims to solve this problem. By recovering and reusing this waste heat, the energy consumption of the system can be significantly reduced, the energy utilization efficiency can be improved, and thermal pollution to the environment can be reduced. In addition, waste heat recovery reduces dependence on external energy, thus contributing to sustainable energy use.
Core principles of waste heat recovery technology
The core of waste heat recovery technology lies in the application of heat exchangers. A heat exchanger is a device capable of transferring heat between two or more fluids. In air source treatment units, waste heat recovery systems usually include the following key components:
Heat recovery device: Installed at an appropriate location in the air handling system to capture and collect waste heat. These devices can be rotary heat exchangers, plate fin heat exchangers, heat pump heat exchangers, etc. The choice depends on the needs and design of the system.
Heat exchange process: In the heat recovery device, the waste heat fluid exchanges heat with another fluid that needs to be heated. Through heat conduction, convection and radiation, waste heat is transferred to the fluid that needs to be heated, thereby realizing waste heat recovery and utilization.
Circulation system: In order to ensure the continuous progress of the heat exchange process, a circulation system needs to be designed to drive the fluid that needs to be heated to circulate between the heat recovery device and the heating target. This system usually includes components such as circulation pumps, piping, and control valves.
