How do energy recovery ventilator of Eunsung Chemical’s Excellent Product?
What functions do Eunsung Chemical energy recovery ventilator products offer?
When pollutants generated indoors are discharged and fresh air is supplied, Eunsung Chemical energy recovery ventilator products can filter ultra-fine dust and save energy using a total heat exchange technology when it cools or heats the air. An automatic temperature control function prevents condensation and mold by operating the internal return damper, and maintains good indoor air quality throughout all four seasons of the year.(Main function: Removes carcinogens, such as ultra-fine dust, carbon dioxide, radon, etc., saves energy across all four seasons, prevents condensation in winter, and prevents mold)
- Bypass, Condensation Prevention Function : All “Health-Friendly” housing (designated by the Ministry of Land, Infrastructure and Transport) must feature this system.
- What is Bypass technology? : When used during spring and autumn, Bypass technology can prevent unnecessary heat exchange and use outdoor air to cool the air indoors, which allows users to save energy across all four seasons of the year.
- What is Internal Return technology? : Internal Return technology prevents condensation and mold without using an electric heater by air with increased temperature to mix part of warm indoor air and cold outdoor air in winter.
Stand-type : Existing buildings
Ceiling Embedded-type : New buildings
Internal Return (condensation prevention) – Working Principles
Product Image
Main Features
- •Internal return : Part of the air to be exhausted through the total heat exchange element in the ventilation system is introduced back to the OA side, mixed with cold outdoor air in winter, and then pre-heated to prevent condensation and mold that can affect the product. It maintains indoor air quality at a comfortable level by securing an effective return air flow rate even during the internal return pre-heating process (increased supply air through the supply fan).
- •Bypass : When used during spring and autumn, bypass technology can prevent unnecessary heat exchange and use outdoor air to cool the air indoors, which allows users to save energy across all four seasons of the year. [All “Health-Friendly” housing (designated by the Ministry of Land, Infrastructure and Transport) must feature this system : Bypass + Condensation Prevention Function]
- •Energy saving in winter : When used in winter, the system does not use the electric heater, which saves energy (saves energy equivalent to the electric heater’s capacity).
- No other company offers a bypass function or condensation prevention function with its products.
- •Function : Total heat exchange + Bypass + Internal return (condensation prevention)
Control system (Compatible with automatic control function)
Automatic control system governed by fine dust sensors
※ Automatic control of air volume from the energy recovery-type ventilator by measuring fine dust and CO2 levels.
- 1. Real-time monitoring of indoor air quality using sensors
- 2. In the case of apartments, ventilation systems can be operated from the remote control or wall pad.
- 3. Eunsung Chemical is planning to develop a solution capable of allowing users to check indoor air quality and operate ventilation systems using their smartphone via the Internet.
- 4. Eunsung Chemical is planning to develop a solution capable of allowing users to check indoor air quality and operate ventilation systems using their smartphone via the Internet.
- 5. The central control system can control ventilators individually or collectively via a PC or analog central controller.
- 6. The central control system also offers an internet-based tablet PC monitoring control function.
