Abstract:
The performance experiments and exergy analysis on a unitary air-conditioner using R404A,R407C and R22 are conducted.The component which losses the maximum amount of the irreversible energy is found.This component will be the preferred component to be improved for the optimization of the system.This paper also analyses exergy loss characteristics of three refrigerants,which provided reference to unitary air-conditioner’s energy saving and refrigerant replacing work.
