The traditional air conditioning fresh air mode (air conditioning fresh air+coil+exhaust fan) used in modern buildings has significant air safety hazards and energy waste. In some projects, the use of a total heat exchanger has saved some energy consumption but increased the air safety hazards; Adopting a single mechanical exhaust mode not only solves quality and air safety issues, but also results in the waste of some thermal energy; The high-efficiency energy consumption problem caused by mechanical continuous ventilation has also become one of the main energy consumption issues in buildings. How to solve indoor air quality problems while ensuring air safety and energy efficiency has become a bottleneck in the development of building ventilation.

ECHR350/ECHR400/ECHR500/ECHR600 digital split type energy recovery unit. The ENH series digital split type energy recovery fresh air unit is an addition of fresh air pre cooling/preheating function on the basis of the HER series digital split type energy recovery unit. The product performance characteristics are the same as those of the HER series digital split type energy recovery unit.

The ENH series digital split type energy recovery fresh air unit is an idealized and efficient energy-saving product developed specifically for indoor air quality and safety assurance in response to the above issues and the characteristics, usage habits, and basic status quo of Chinese buildings.

The ECHR350/ECHR400/ECHR500/ECHR600 digital split type energy recovery unit is widely used in places with high requirements for hygiene and energy consumption due to its high safety, high intelligence, high efficiency and energy saving, flexible installation, and simple maintenance.

Composition and principle of ENH

ENH consists of an EC digital high-efficiency energy-saving fan with a digital signal interface, a surface cooling section, a fresh air heat exchange section, and a filtering initial effect device. Through the circulation of heat recovery liquid, the heat in the exhaust air is transferred to the fresh air, thereby preheating or pre cooling the fresh air. This type of sensible heat recovery is called liquid circulation heat recovery, also known as intermediate heat recovery, and its device is called a liquid circulation heat recovery device. The structure and principle of a heat exchanger are the same as those of a general water air heat exchanger. The circulating liquid is a solution of ethylene glycol (referred to as ethylene glycol) added in a certain proportion, and the mass percentage of the ethylene glycol solution depends on the low outdoor temperature in the local winter.
