Embodiment Construction

[0029] Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings of FIGS. 1 to 7 .

[0030] 5 shows a schematic front view of the refrigerator. The refrigerator 1 has a refrigerator compartment 3, a vegetable compartment 5, an ice compartment 7, a switch compartment 9, and a freezer compartment 11 in order from above.

[0031] Refrigerator compartment 3 and vegetable compartment 5 are cooled by first evaporator 13 as shown in FIG.

[0032] Fig. 6 is used for showing the refrigerating cycle diagram, in addition to above-mentioned the 1st, the 2nd evaporator 13,15, also has the 1st, the 2nd throttling device 21,23 of compressor 17, condenser 19 and containing capillary, and A refrigeration cycle is formed. The refrigerant discharged from the compressor 17 passes through the condenser 19 and the three-way valve 25 , on the one hand, passes through the first evaporator 13 from the first throttling device 21 , and returns to t...

Abstract

The invention provides a refrigerator using the refrigerant moderate to earth environment with small operating noise. The invention is connected through the order of a refrigerant pipe (29) after sealing R290 (propane) refrigerant, a compressor (17), a condenser (19), a throttling device (21, 23) and an evaporator (13, 15) to form refrigerating cycle. The refrigerant discharged from the compressor (17) passes through the condenser (19), the throttling device (21, 23) and the evaporator (13, 15) finally back to the compressor (17). On the other hand, the discharging side refrigerant pipe (29) of the compressor (17) is provided with a muffler (31) to restrain the discharging fluctuation from the compressor. The muffler has a length L more than or equal to 35 mm and less than or equal to 210mm.

Description

technical field [0001] The present invention relates to a refrigerator suitable for using R290 (propane) in the refrigerant. Background technique [0002] Generally, the refrigeration cycle is constituted by the refrigerant discharged from the compressor passing through the condenser, throttling device, evaporator and returning to the compressor again. The use of refrigerants in the refrigeration cycle is to replace Freon-based refrigerants with non-freon refrigerants based on the environmental problems of the earth, and to use flammable refrigerants in the refrigerants that make up the refrigeration cycle of refrigerators has become a well-known product. Methods. [0003] Compressors, condensers, throttling devices, and evaporators that make up the refrigeration cycle have been designed to maximize performance on the premise of using freon-based refrigerants. However, if flammable refrigerants are used as refrigerants, physical damage will occur. Performance is different ...
