Problems solved by technology
[0002] At present, the refrigerator refrigeration system is generally connected by a capillary tube to an evaporator, so there is a mutual restriction relationship between the evaporation pressure and the flow rate. For example, to increase the flow rate, it is necessary to shorten the capillary tube and increase the evaporation pressure; When starting up, it takes about 20 minutes for the evaporator to balance, and the evaporation area cannot be used more effectively, resulting in a waste of resources and a decrease in efficiency; a capillary tube often causes the flow direction of the refrigerant in some evaporators to be consistent with the flow direction of the convective air, reducing the exchange rate.

The invention relates to a dual-capillary-tube refrigerator refrigerating system comprising a compressor, a condenser, a filter, capillary tubes and an evaporator which are connected in sequence to form a loop, wherein the capillary tubes comprise a first capillary tube and a second capillary tube which are parallel; the evaporator is divided into a first portion evaporator and a second portion evaporator which strike in parallel; the first capillary tube is connected with the first portion evaporator; the second capillary tube is connected with the second portion evaporator; and the outlets of the first portion evaporator and the second portion evaporator are connected with the compressor through a muffler. The invention overcomes the mutual restraint relation between the evaporation pressure and the flow, simultaneously shortens the balance time of the inlets and the outlets of the evaporator when the compressor is started up each time, can more effectively utilize the evaporation area, improves the evaporation efficiency and solves the problem that the heat exchange efficiency is reduced because the flow direction of a part of refrigerating fluid of the evaporator is consistent with the flow direction of convection air when one capillary tube is used.
