PROBLEM TO BE SOLVED: To provide heating which is felt suitable independent of the air volume during operation of a heat pump. SOLUTION: A condenser temperature-calculating part 20 consists of a map showing the correlation between a set temperature and the solution temperature Tc for having warm air at the set temperature and calculates the solution temperature Tc inside the condenser 9 based on an inputted set temperature. A vapor pressure-calculating part 22 has a solutionvapor pressure characteristic chart and, with a solution temperature Tc as the input, calculates the vapor pressure Pc in relation to the temperature Tc. A comparison part 23 compares the output Ps of a pressure sensor PS9 with the calculated vapor pressure Pc. On the basis of the result of the comparison by the comparison part 23, a burner adjusting part 24 controls a burner 7, for example, in a manner of increasing the amount of heating when the condenser pressure Ps in the sensing is lower than the calculated vapor pressure Pc. As a result, the air discharged from an indoor unit is maintained at a temperature corresponding to the condenser pressure Ps. |
