摘要

Clean-Air Heat Pump (CAHP) is an innovative system which combines a desiccant wheel with a heat pump which can improve indoor air quality during the process of hygro-thermal control without using additional energy. It is verified that organic gaseous pollutants in air can be effectively removed by the CAHP in our previous research papers but whether the air purification capability of the CAHP is equally effective for inorganic pollutants is unknown. Therefore, in this paper, the removal of ammonia (NH3)-one typical inorganic pollutant by the CAHP was focused, and the effects of regeneration air temperature of the rotor and NH3 concentration on NH3 removal were elaborated analyzed. The results showed that NH3 could not be continuously removed when the adsorbent-silica gel in the CAHP was regenerated by low-temperature thermal energy like 60 degrees C. A higher regeneration air temperature, possibly more than 90 degrees C, was required, in which case NH3 removal and desorption efficiencies reached 86.5% and 93.8% when the NH3 concentration was 2.5 ppm. Even if the NH3 concentration in process air was increased to 7.1 ppm, the air cleaning efficiency was still maintained above 67%.
