Working Principle of the Heat-Pump Fresh-Air Ventilator
The heat-pump fresh-air ventilator is a device that combines fresh-air ventilation with heat-pump technology. By recovering heat or cooling from indoor and outdoor air, it achieves efficient ventilation and energy savings. Its working principle is mainly based on the refrigeration/heating cycle of the heat pump and air heat-exchange technology. The detailed working principle is as […]
How to Distinguish the Tube Side and Shell Side of a Heat Exchanger
In a heat exchanger, the tube side and shell side are distinguished by the fluid flow path, mainly based on their structure and working principle. The following is a concise explanation: 1. Tube Side Definition: The path through which fluid flows inside the tube bundle (i.e., inside the tubes) of the heat exchanger. Characteristics: Fluid […]
Application of Heat Recovery Units in Drying Exhaust Waste-Heat Recovery
In drying exhaust waste-heat recovery, heat-recovery units are mainly used to recover thermal energy from the high-temperature exhaust gas emitted during the drying process, improving energy efficiency and reducing consumption. The following describes their application and key points: 1. Application Scenarios Heat-recovery units are commonly used for waste-heat recovery from exhaust gas emitted by drying […]
