The Impact of Energy Recovery on Window Air-conditioner Efficiency
MetadataShow full item record
An experimental energy recovering air-conditioner can produce fresh air exchange heat with exhaust air in the heat exchanger, which has no additional moving parts. The EER of the experimental air-conditioner (EAC) is increased by 17.4~37.3 percent over that of an ordinary window type air-conditioner (OAC), which is very significant for energy efficiency. On the other hand, the fresh air proportion of the EAC is increased by ~20 percent over that of the OAC, and the indoor noise of the EAC is decreased by ~3.8 dB. Therefore, indoor environment quality can be greatly improved with the EAC.
