Abstract: A refrigeration system, particularly for controlling the temperature of an environment, and presenting a compressor; a condenser; a laminating thermostatic valve; an evaporator; an evaporation pressure control valve interposed between the outlet of the evaporator and an inlet of the compressor; an economizer in turn presenting a laminating orifice downstream from the condenser, and a flash tank with an inlet communicating with the orifice, a liquid-phase outlet connected to the thermostatic valve, and a gaseous-phase outlet connected to an intermediate inlet of the compressor; and a tapping valve interposed between the outlet of the compressor and the flash tank, and which is opened when the pressure in the flash tank falls below a predetermined threshold value.
