    摘要: The regulator is a refrigerant regulator intended for heatpumps and refrigerators. It has a built-in receiver, which automatically absorbs redundant refrigerant. It is a hermetic closed device without removable parts. It is robust and there is no need for adjustment. The regulator is composed of a heat exchanger with large heat capacity, a receiver and two pressure reducing valves. The two valves behave different on boiling fluid flow. One of them, named a heat sensitive valve, restricts fluid flow when the fluid is boiling. In the other valve, named a pressure sensitive valve, the boiling has no influence on the fluid flow. The regulator controls the refrigerant flow from the receiver to the evaporator by means of the pressure in the receiver - and the pressure in the receiver is controlled, via the heat exchanger, by the need of refrigerant in the evaporator. This way of control ensures 100% use of the evaporator, the suction gas is superheated, and the liquid from the condenser is sub-cooled. These factors improve the relation between the cooling capacity and the power consumption with more than 10%.

    摘要: Procédé pour l'injection du fluide frigorigène dans une armoire frigorifique monocompresseur à deux compartiments à températures différentes permettant d'obtenir des valeurs fixes de température dans chaque compartiment lorsque la température d'ambiance varie entre une valeur minimale et une valeur maximale.
    La régulation est effectuée grâce à un thermostat (T) placé dans le compartiment à température plus haute, et le fluide, après compression, est injecté en série dans une première partie (121) de l'évaporateur (120) du compartiment à température plus haute, dans l'évaporateur (110, 111) du compartiment à température plus basse, et dans une seconde partie (122) de l'évaporateur du compartiment à température plus haute avant de retourner au motocompresseur (20).
    La connaissance des rapports des besoins frigorifiques entre les deux compartiments aux températures extrêmes d'ambiance permet de déterminer les rapports des longueurs et/ou surfaces utiles entre les deux parties (121, 122) de l'évaporateur du compartiment à température plus haute.

    摘要: The present invention belongs to the technological field of cooling systems. A multiple-evaporation cooling system with two or more evaporation lines is disclosed. In a first intermediate heat exchanger (62), the first evaporation line (Levap1), preferably the portion defined between the evaporator (51) and the suction inlet (11) of the compressor (1), is in heat exchanging contact with at least one segment of the expansion device (42) of the second evaporation line. In a second intermediate heat exchanger (61), the second evaporation line (Levap2), preferably the portion defined between the evaporator (52) and the suction inlet (12) of the compressor (1), is in heat exchanging contact with at least one segment of the expansion device (41) of the first evaporation line. The temperature of the intermediate heat exchanger of first evaporation line (62) influences the temperature of the refrigerant flowing in the second line of evaporative expansion device (42) and the temperature of the intermediate heat exchanger of the second evaporative line (61) influences the temperature of the refrigerant flowing in the first line of evaporative expansion device (41). The invention in question is distinguished for varying the restriction of the respective expansion devices (41,42) and then unduly inhibit mass transfer of refrigerant between at least two distinct evaporators (51,52).
