Abstract

Based on the air purification capacity of regenerative silica gel rotor, an innovative clean air heat pump (CAHP) was designed, developed and investigated through experimental studies. The CAHP integrated air purification, dehumidification and heating/cooling in one unit. A prototype of the CAHP was developed. Laboratory experimental studies were conducted to investigate its energy performance under different outdoor climates including cold, mild-cold, mild-hot and extremely hot and humid climates. The energy performance of the CAHP was then evaluated by comparing with a conventional air source heat pump. The results showed that to keep same indoor air quality, the CAHP could save substantial amount of energy. For example, compared to the conventional air source heat pump, the CAHP could save up to 59%, 40%, 30% of electricity for ventilation and air conditioning in a test room in summer of Copenhagen, Milan and Colombo, and could save 5%, 13% of electricity for ventilation and heating in the test room in winter of Copenhagen, Milan.
