<p><P>PROBLEM TO BE SOLVED: To improve the estimation accuracy of condensation pressure and evaporation pressure in a refrigerating device using a non-azeotropic refrigerant mixture as a refrigerant. <P>SOLUTION: In an air conditioner 1, a control part 4 first estimates an evaporation temperature Te after setting a temporary condensation temperature Tc. Next, by using the temporary condensation temperature Tc and the evaporation temperature Te, work performed by a compressor 11 is calculated. Operation for correcting the temporary condensation temperature Tc until the calculated work performed by the compressor 11 and an actual input value of the compressor 11 correspond to each other is repeated. When the calculated work performed by the compressor 11 and the actual input value of the compressor 11 correspond to each other, the condensation pressure and the evaporation pressure are determined based on the temporary condensation temperature Tc and the evaporation temperature Te. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
