Problems solved by technology
[0003] When the ambient temperature is relatively high or a large amount of food is put in at one time, the refrigeration system cannot meet the cooling demand of each compartment in time, resulting in a high temperature rise in the box, or a slow cooling rate, which affects food preservation and freshness
[0004] A certain room is frequently used, and the refrigeration system cannot take care of other rooms, or because of continuous cooling, the room temperature that shares a series evaporator with this room is too low, freezing the food in the box
[0005] The evaporation temperature of each compartment is different, resulting in unstable operation of the compressor
[0006] When two or more compartments need to be refrigerated, because the refrigeration system can only refrigerate one refrigeration circuit, the compartments in the refrigeration circuit must wait for a certain period of time, which affects food storage and preservation

Embodiment Construction
[0016] See figure 1 , The first branch is formed by the first compressor 1, the first evaporator group 11 and the first throttling unit 9 connected in series; the second compressor 2 is connected in series with the second evaporator group 12 and the second throttling unit 10 The second branch is formed. The first branch and the second branch are connected in parallel in the refrigeration cycle including the condenser 5 and the filter 6. The first branch and the second branch share a condenser 5 and a Only the filter 6 forms two independent refrigeration cycles.
[0017] The discharge ports of the first compressor 1 and the second compressor 2 are connected to the condenser 5 through the first discharge check valve 3 and the second discharge check valve 4 respectively, so that the high-pressure refrigerant in the condenser 5 will not Reverse flow to the compressor; between the discharge port of the first compressor 1 and the first discharge check valve 3, the first throttle unit 9 ...

This invention relates to one compressor refrigerator, which comprises the following parts: first branch composed of first vapor set and first flow saving units; second branch composed of second vapor and second flow save unit; cooling recycle loop composed condensator and filter with each exit mouth connected through exit mouth between compressor and exit single valve through load unit into branch flow save entrance with branch terminal valve.
Description
Technical field: [0001] The invention relates to a vapor compression type refrigerator. Background technique: [0002] Usually refrigerators use a compressor, a condenser, etc. to form an independent refrigeration system. An independent refrigeration system has been expanded into a related multi-cycle refrigeration system through solenoid valve diversion or control of the flow of refrigerant, for example, mechanically controlled refrigerating and freezing boxes, dual-temperature dual-control refrigerators, three-cycle refrigerators, and four-cycle refrigerators. Refrigerators, etc. This type of multi-cycle structure based on a refrigeration system has the following shortcomings: [0003] When the ambient temperature is relatively high or a large amount of food is put in at one time, the refrigeration system cannot meet the cooling demand of each compartment in time, resulting in a higher temperature rise in the box, or a slow cooling rate, which affects food preservation and fres...
