A Study on a Novel Solar Heating and Humidification System with Desiccant Rotor
In this paper, a solar space heating system, which combines the technologies of evacuated tube solar air collector and desiccant humidification together, has been configured and experimentally investigated. In winter, two operation modes are possible, namely, direct solar heating mode and solar heating with desiccant humidification. Besides, the system can work in cooling mode in summer. The system mainly includes 15 m2 solar air collectors and a desiccant air conditioning unit with design cooling capacity for 5 kW. The system has been put into operation and its heating performance has been monitored from November 2008 to March 2009. Under typical weather condition, it is found that the solar heating system can convert about 50％ of the received solar radiation to the capability of air conditioning in sunny day and provide fresh air above 30℃, thereby increasing the temperature of conditioned space by about 10℃. Moreover, solar heating with desiccant humidification is confirmed to be capable of improving indoor relative humidity from health harmful level to comfort level. Due to the absence of water, which has to be employed in traditional evaporative humidification based systems, desiccant humidification based solar heating holds significant promise for the improvement of indoor air quality.
