In this way, a cooling system is provided which allows the adjustment of the composition of your mixture to be carried out under favorable conditions. In particular, adjustment in view of customer temperature speakers and / or ambient temperature will change as the composition of the refrigerant mixture changes during cooling.
As used herein, the term "customer" means a cooling duty, which is to be cooled by the cooling system. Apart from what is described here, detailed distribution friamiento, or its working principle, is not critical to the present invention.
The system may comprise a retention tank adid by an additional recovery conduit to the cooling circuit between the separator (s) and the customer, the retention tank. to position between the customer and the compressor input. A fraction is only kept in its holding tank at the pressure of either slightly or slightly below. Since the separator (s) typical of the high-pressure side of the cooling circuit, it is beneficial to supply refrigerant from its holding tank via the cooling duct, in a position between the customer and the compressor or low pressure inlet of the cooling circuit. cooling. In this way, this cooling fraction is without cooling circuit, or with less mbas or other pressure regulating means. Therefore, the portioning with one or more holding tanks that maintain the pressure in the cooling circuit, where the pective fraction is separated and the pressure in the cooling circuit where minister is connected.
Each recovery conduit can also be connected a recovery fraction is not of suitable purity, it is left of the cooling circuit, instead of being stored and / or reused to fraction of refrigerant separated and recovered from the refrigerated mixture.
The system can be configured to be regulated by a control device with control signaling infrastructure to the quantities in each holding tank, for example psion and the control device can also track the refrigerant in the system by A multiple co-positive control detector can also determine the speed and length of different control valves, according to which adjustment is required.

In this way, eference all the fraction or fractions recovered in stage a) can individually. Store the fractions recovered individually, such as recovery or recycling thereof. Any acenada can be discarded, for example burned. A fraction can only be discarded, instead of stored, if this fraction is nvenient.
In order not only to avoid or reduce the refrigerant discharge by a convenient closure of the operation of a refrigeration process, the refrigerant stream supplied in stage b) may preferably consist of one or more of the storage fraction (s). recovered from the cooling system of multiple refrigerators can be returned, although in amounts and / or proportions mbie the composition of the refrigerant mixture of cooling system rigerantes. Replenishing refrigerants, not recovered from the system of the last refrigerants, but typically supplied substantially with a set composition, can conveniently be used. frigid Occasionally, it may not be useful to store any frac of the refrigerant mixture, that is, the fractions recovered in the discarded e r. As mentioned earlier, this or these fractions are emadas. In this situation, the number of fractions recovered in the r conveniently one. Replacement refrigerants, not withdrawn from multiple refrigerants, but typically substantially bistantially supplied or in mixtures of a stated composition are to be supplied to the refrigerant cooling system of the refrigerant stream of stage b).
The one or more stored fractions can be mixed between the pressure of the refrigerant mixture in the position d cooling of multiple refrigerants, where in stage a), the fraction cures and the pressure of the refrigerant mixture in the cooling position. wherein stage b) is carried out. In alternate form or additions removed in stage a) each can be removed in a cooling position of multiple refrigerants, where the refrigerant mixture where gaseous carbon dioxide is captured as temperature dioxide ice.
