【Abstract】 The secondary air exchange HVAC system is commonly combined with under seat air distribution system (USAD) to achieve the requirement of higher temperature supply air. The control strategies of this system affect the humidity and temperature of indoor environment and building energy conservation. This paper presents the basic control strategies of secondary air exchange HVAC system. Through the analysis from practice, this system with proper control strategy can save 20% of electricity. The strategy of frequency conversion in pumps can reduce 71% of electricity when comparing to the normal system.更多还原
