Abstract
A method for selecting a heat medium in installing an air-conditioning system includes: determining power required for use side heat exchangers corresponding to a plurality of air-conditioned spaces; calculating a total refrigerant amount required when a refrigerant is circulated through all the use side heat exchangers having the determined power; calculating a refrigerant concentration when the total refrigerant amount leaks to each air-conditioned space using the refrigerant, for each air-conditioned space; determining the refrigerant concentration for each air-conditioned space exceeds a predetermined limit concentration; when any air-conditioned space exceeds the limit concentration, selecting, as a nontoxic medium, the circulation heat medium of the use side heat exchanger installed in one of the air-conditioned spaces; and calculating a total refrigerant amount required when the refrigerant is circulated through all other use side heat exchangers.
