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.
Claims6
A system for controlling the temperature of an environment including a refrigeration system (4) having means (10) for compressing a refrigerant;
- a condenser (16) connected to the outlet (13) of said compressing means (10);
- a first orifice (25);
- an evaporator (27) having an inlet (26) connected to said first orifice (25), and an outlet (33) connected to an inlet (11) of said compressing means (10);
- characterized in that said refrigeration system comprises, in combination:
- an evaporation pressure control valve (35) interposed between said outlet (33) of said evaporator (27) and said inlet (11) of said compressing means (10);
- an economizer (43) having a second orifice (19) connected to the outlet (17) of said condenser (16);
- and a flash tank (21) having an inlet (20) connected to said second orifice (19), a liquid-phase outlet (23) connected to said first orifice (25), and a gaseous-phase outlet (22) connected to an intermediate inlet (12) of said compressing means (10);
- and
- tapping means (37, 38) connecting said outlet (13) of said compressing means (10) to said inlet (20) of said flash tank (21).
