Description

ViaoGpeTGHHe refers to a technique that is suitable for it, namely, a two-chamber household hopper. Known dd -hkamerny homepage hopodipnnk working on a zeotropic mixtures hpadagentov comprising parappepno installed in the respective chambers and low temperature environments netemperaturny evaporators, a compressor capacitor consisting of two pospedo tepno soedinenshlh sections, between which the liquid separator is mounted, in communication with one of the capacitor sections L I. soldering tube. The disadvantages of this refrigerator include the inability to work on a single component working temperature and the complexity of the design. ii, obuslovpenne using zeotropic mixture hpadagentov. Another two-chamber household hood is known, containing a low-temperature and medium-temperature evaporator, a hermetic compressor and throttling organs; installed in front of the evaporators 2 - Odkako; the refrigerator does not provide stable temperatures in the freezer and fridge: here; chambers. The purpose of the invention is to ensure the stability of the specified temperature zones in both hoopipnik chambers. This is achieved by the fact that the hermetic compressor has a dispensing cavity, the evaporators are connected: in parallel, the output of the low-temperature evaporator is connected to Em: the outlet of the compressor cavity, and the output of the medium-temperature evaporator to the compressor discharge temperature. FIG. I schematically depicts the proposed refrigerator, a general view of FIG. 2 - hermetic reciprocating piston compressor with a dispensing cavity. The two-chamber home refrigerator includes a freezer 1 n refrigerated 2 chambers with correspondingly kilograined 3 n medium-temperature 4 evaporators placed inside them, each connected to each other by a vapor-tight, sealed reciprocating compressor Sj with an airy KOK-iiipeccop 65 throttle body. Installed in front of the appropriate ZnaparEggel Zi4, and regenerative heat exchangers 9 and 10. Compressor 5 (Fig. 2) COCIXJHT does not have a sealed closed compartment 11 inside of which is enclosed by an electric vehicle 12 and combined with common heat exchanger
