The invention discloses a double-capillary-tube refrigerating system of a refrigerator and particularly relates to the technical field of refrigerating systems of refrigerators. The problem that an existing refrigerator adopts a single-capillary-tube refrigerating system and a refrigerating chamber is prone to icing under a low-temperature working condition is solved. The double-capillary-tube refrigerating system of the refrigerator comprises a compressor, a condenser set and a dry filter which are sequentially connected through pipelines. The dry filter is connected with a refrigerant channel. The refrigerant channel comprises a first refrigerant passage and a second refrigerant passage, the first refrigerant passage and the second refrigerant passage are connected in parallel, the first refrigerant passage is connected with a first capillary tube in series, and the second refrigerant passage is connected with a controller and a second capillary tube in series. Flow of the first capillary tube is equal to flow of the second capillary tube. The output end of the refrigerant channel is connected with a freezing evaporator set. The output end of the freezing evaporator set is connected with a refrigerating evaporator set. The output end of the refrigerating evaporator set is connected with the compressor.
Description
technical field [0001] The invention belongs to the technical field of refrigerator refrigeration systems, and in particular relates to a double-capillary refrigerator refrigeration system. Background technique [0002] Existing mechanical temperature control multi-door refrigerators all control the start and stop of the whole refrigerator by adopting a thermostat set in the cold room. When the ambient temperature drops, the evaporating temperature of the refrigeration system of the refrigerator decreases, the system flow decreases, and the cooling speed decreases, resulting in a long start-up time of the refrigerator and an increase in power consumption. At the same time, due to the longer working time of the refrigerating evaporator, the temperature of the refrigerating room continues to drop, which is very prone to freezing, which is not conducive to food preservation. Contents of the invention [0003] The purpose of the present invention is to solve the problem that ...
