Zusammenfassung: | To further reduce the power consumption of vending machines that have heating systems that can warm product storage rooms.SOLUTION: A vending machine includes: a heating system configured to be able to heat a commodity storage room, the heating system comprising a compressor for compressing and discharging a refrigerant, an indoor heat exchanger disposed in the commodity storage room, a decompressor for decompressing the refrigerant, and an outdoor heat exchanger disposed outside the commodity storage room; a pressure sensor for detecting the pressure of the discharged refrigerant of the compressor; and a control unit for controlling the operation of the heating system. The compressor is an inverter compressor. The control unit operates the compressor at a first rotation speed after starting the compressor (S2, S3), and thereafter changes the compressor to operate at a second rotational speed lower than the first rotational speed when the pressure of the discharged refrigerant of the compressor reaches predetermined pressure (S4, S5).SELECTED DRAWING: Figure 7
【課題】商品収納室を加温可能な加温システムを有する自動販売機の消費電力量のさらなる削減を図る。【解決手段】自動販売機は、商品収納室を加温可能に構成された加温システムであって、冷媒を圧縮して吐出する圧縮機と、前記商品収納室内に配置された室内熱交換器と、冷媒を減圧する減圧器と、前記商品収納室の外部に配置された室外熱交換器とを有する前記加温システムと、前記圧縮機の吐出冷媒の圧力を検出する圧力センサと、前記加温システムの動作を制御する制御部とを含む。前記圧縮機は、インバータ圧縮機であり、前記制御部は、前記圧縮機を起動した後に前記圧縮機を第1回転数で動作させ(S2、S3)、その後、前記圧縮機の吐出冷媒の圧力が所定圧力に到達すると前記圧縮機を前記第1回転数よりも低い第2回転数で動作させるように構成されている(S4、S5)。【選択図】図7 |
