DYMACHINE Waste Heat Recovery Unit

A waste heat recovery device is an economical and environmentally friendly device that uses a heat exchanger as the main component to transfer excess heat generated by one device to another for heating or energy conversion. For ordinary buildings, the most commonly used waste heat recovery device is air heat recovery equipment.

The commonly used waste heat recovery equipment in buildings is air heat recovery equipment. Air heat recovery equipment refers to equipment that recovers waste heat inside and outside the building and uses the recovered heat as a heat source for heating or other heating equipment. It usually consists of a supply and exhaust fan, a heat recovery device on the air side, an air filter, and other auxiliary equipment, usually equipped with an electrical control device. There are many types of air heat recovery devices, each with its own advantages and disadvantages.

According to different working principles, air air heat recovery devices can be divided into several common forms: rotary heat exchangers, plate and plate fin heat exchangers, heat pipe heat exchangers, intermediate media heat exchangers, and solution absorption heat exchangers. The recovery efficiency, equipment costs, and maintenance characteristics of different forms of heat recovery devices also vary.

According to the different types of heat recovery, heat recovery can be divided into total heat recovery and sensible heat recovery. The total heat recovery device can recover both sensible heat and latent heat, including rotary heat exchangers, plate fin heat exchangers, and solution absorption heat exchangers. The sensible heat recovery device can only recover sensible heat, and specific types include intermediate heat medium heat exchangers, plate heat exchangers, and heat pipe heat exchangers. According to different recovery methods, air heat recovery devices can be divided into static recovery devices and dynamic recovery devices. Dynamic recovery device refers to a recovery method with dynamic exchange on the air side, specifically a rotary heat exchanger. Static recovery refers to several other recovery methods without dynamic exchange on the air side.
