6. Conclusions
This study shows the feasibility of an ORBCR using moist air for air conditioning cooled by circulating
water. The calculation results show:
The ORBCR given in this paper is new concept and its working fluid is the mixture of air and vapor. Its
refrigeration depends mainly on both the sensible heat of air and the latent heat of water vapor, and differs
from a conventional air-cycle system. The use of turbo-machinery with high efficiencies makes this
possible.
Comparing with air-vapor compression refrigeration system for air conditioning cooled by circulatingwater[
15], this ORBCR is more efficient for air conditioning.
The COP and equivalent COPE of this ORBCR rests mainly on ηc andηt. The temperature of turbine
inlet will also affect it heavily. although the sensitivity of the COP and equivalent COPE toηc andηt , the
ORBCR using moist air for air conditioning cooled by circulating water is still feasible.
