PROBLEM TO BE SOLVED: To provide a refrigerating or air-conditioning device using a vapor compression refrigerating cycle, which achieves efficiency and advantage higher than a conventional vapor compression refrigerating cycle, by changing a basic cycle in the vapor compression refrigerating cycle, that is, by changing the basic cycle of the vapor compression refrigerating cycle from reverse Carnot cycle to reverse Ericsson. SOLUTION: This vapor compression refrigerating cycle is constituted by disposing a compressor (2), a condenser (4), a regeneration heat exchanger (6), an expansion means (8), and an evaporator (10) in series. This cycle is the reversed Ericsson cycle in which isothermal heat dissipation process and isothermal heat absorption process occur over a saturated vapor line and saturated liquid line, and heat exchange is carried out between isobaric heat dissipation process in a liquid zone and isobaric heat absorption process in a superheated vapor zone.
