| 摘要 |
An economical heat-pump heating installation is presented, which can be operated continuously in the partial-load range between 0 and 100%. It consists of a continuously working heat pump driven by an internal combustion engine or an electric motor, a small heat reservoir and one or two peak-load boilers which work in modulating fashion. The continuous heat-pump operation is achieved by an improved refrigerant compressor which contains, in addition to its continuously working volume-controlling device, a device for adapting the compression ratio to the saturation pressures, reduced in the partial-load range, in the refrigerant condenser. In addition, the heat pump works with an improved thermodynamic cyclic process, since it utilises extended condensate undercooling to heat the domestic water. |
