Zusammenfassung: | PURPOSE:To reduce a storage temperature down to an optimum temperature for vending cold commodities by switching a condensing unit in a freezer to continuous running at the time of switching a hot-and-cold (H/C) room from hot running to cold running. CONSTITUTION:An electromagnetic valve 14I on the cold(C) room side is controlled so as to be opened/closed by the operation of a storage temperature controller 12I independently of the operation mode of the H/C room. An electromagnetic valve 14II on the H/C room side is controlled so as to be opened/ closed by the operation of a storage temperature controller 12II in the state selecting the cold operation mode of the H/C room. On the other hand, the condensing unit 4 in the freezer is thermostatically operated by the controller 12I of the C room side in the hot running mode state of the H/C room, and when the H/C room is switched to the cold running mode by an operation mode changing switch 15, thermostatically operated by the controller 12II of the H/C room side. |
