Energy recovery ventilation (ERV) is the process of exchanging the energy contained in normally exhausted building air and using it to precondition the incoming outdoor ventilation air. This system improves indoor air quality while reducing the total HVAC equipment capacity required for heating and cooling.
Our slim ventilators are designed specifically for projects with strict installation height requirements. Compared with traditional products, the slim height is reduced by 20%. The access door is located at the bottom, making maintenance significantly easier in tight ceiling spaces.
Equipped with a crossflow enthalpy exchanger, the efficiency reaches up to 82% in winter. The moisture exchange between fresh and exhaust air maintains comfortable indoor temperature and humidity levels year-round.
Calculation Example:
Room area: 60 sq. meters, Height: 3 meters, Occupants: 10 persons.
1. Based on personal consumption (70 m3/h per person): Q1 = 10 * 70 = 700 m3/h.
2. Based on air changes (5 changes per hour): Q2 = 5 * 60 * 3 = 900 m3/h.
Result: 900 m3/h is recommended for better air quality.
As a leading manufacturer specializing in air-to-air heat recovery equipment for over 16 years, we supply a wide range of products across 20 series. Our facilities feature national approved labs and certifications including ISO9001, ISO14001, OHSAS18001, CE, and RoHS. Every unit undergoes 100% testing before leaving the factory.
