Title:
ヒートポンプ熱源機
Document Type and Number:
Japanese Patent JP7032993
Kind Code:
B2
Abstract:
To improve efficiency of a device as a whole by reducing an operation intervention ratio of an auxiliary power source.SOLUTION: A heat pump heat source machine 1 has compressor control portions 61A, 62A applying one of a first compressor 43 and a second compressor 53 as a main power source and applying the other as an auxiliary power source, and a return temperature sensor 34 detecting an actual temperature of circulation liquid in a load pipe 31. The compressor control portions 61A, 62A include temperature zone determination portions 61b, 62b for determining temperature zones a-g determined on the basis of deviation ▵T2 between the detected actual temperature and a target temperature, and upper limit value determination portions 61c, 62c for determining a first upper limit value of the main power source and a second upper limit value of the auxiliary power source for each of the temperature zones a-g so that the larger the deviation ▵T2 is, the larger the first upper limit value and the second upper limit value become, while keeping the second upper limit value to be the first upper limit value or less, in operation states of both of the main and auxiliary power sources.SELECTED DRAWING: Figure 14
