Indoor air quality situations


In modern architecture, due to the widespread use of air conditioning, buildings become more and more tight in order to save energy. The natural air exchange rate in the modern buildings has reduced significantly.

It is harmful to the human health if the air in the air-conditioned room is too dreggy. In 1980, the World Health Organization officially named these diseases as Sick Building Syndrome or Air-conditioning Sickness.

Common pollutants that might affect indoor air quality:
• Biological Contaminants
• Construction Materials
• Combustion Products
• Chemical Contaminants
• Electrical Equipment Pollution
• Outdoor Pollutants

Fresh air and energy consumption


• To increase the fresh airflow is a good way to improve the air quality, but at the same time the energy consumption will rise dramatically.
• Building energy consumption counts up to 25% of the annually total energy consumption in China .
• The energy consumption of HVAC counts over 60% of the total building energy consumption
• As to the public buildings, to condition 1 m 3 /h fresh airflow need consume about 9.5 kw.h energy in the whole summer.

Energy shortage is a problem worldwide, so the energy saving on HAVC systems is critical.

Energy recovery devices are effective ways to solve the problem between fresh air and energy saving. Many countries have published regulations on pushing the use of energy recovery devices.
