Abstract
Clean air heat pump (CAHP) is a new system, which combines desiccant wheel with heat pump to improve indoor air quality without additional energy consumption. CAHP can effectively remove the organic gaseous pollutants in the air, such as formaldehyde and acetone, but it is not clear whether it is equally effective in the purification of inorganic pollutants. This study focuses on the effect of regeneration air temperature and NH3 concentration on NH3 removal capability by CAHP. The results show that the NH3 cannot be removed continuously when the silica gel in CAHP is regenerated by low temperature thermal energy such as 60 ℃. At 90 ℃, when the concentration of NH3 is 2.5ppm, the removal rate and desorption rate of NH3 are 86.5% and 93.8%, respectively. Even if the NH3 concentration in the process air is increased to 7.1ppm, the air purification efficiency remains above 67%.
