Return-air heat exchange portion by capillary 131 with muffler 132 and put and form.Return-air heat exchange portion comprises the first return-air heat exchanging segment 130, and this first return-air heat exchanging segment 130 is arranged on the rear side (being the left side among Fig. 1) of casing 110 and between said case courage 112 outer walls and said case shell 111 inwalls of refrigerating chamber 1 part.
Specifically describe the operation principle of the refrigerating plant 100 of the embodiment of the invention below.Need to prove; Following description is that the direct-cooling type refrigerating plant is that example describes with said refrigerating plant 100; But the present invention is not limited to this; So long as in the case courage, be limited with all applicable the present invention of the cool room refrigerating plant of refrigerating chamber, such as the two-door refrigerator that comprises refrigerating chamber and refrigerating chamber, comprise all applicable the present invention such as multi-door refrigerator of 3 or above warm area.And for corresponding each distortion, on the basis of following description, do simple accommodation for the person of ordinary skill of the art and can it easily understand corresponding work principle separately.
In the present embodiment, said refrigerating plant 100 is the direct-cooling type refrigerating plant, and its refrigeration system comprises compressor 20, condenser, device for drying and filtering, capillary 131, evaporimeter and the muffler 132 that connects successively.Refrigeration system utilizes the circulation of cold-producing medium to carry out heat exchange, in the air of transfer of heat outside refrigerating plant 100 in the refrigerating plant 100, reaches the purpose that makes refrigerating plant 100 coolings.Need to prove that because condenser, device for drying and filtering, evaporimeter all adopt conventional parts, it is provided with the position also is that refrigeration plant is made the position that field institute is provided with usually, so omits its diagram in the drawings.
Downstream at compressor 20 are connected with condenser.Condenser is called radiator again, is a kind of heat exchanger that the heat transferred of cold-producing medium is extraneous, and the back that is installed in casing 110 is near the lower end.The effect of condenser is high temperature, the high pressure refrigerant vapor that compressor is discharged, in the transmission that the condenser back warp is crossed heat, the ambient air heat radiation, make the refrigerant vapour cooling become then in the liquid refrigerant of warm high pressure.In order to make around the doorframe not dewfall, can also be provided with doorframe defrosting pipe (not shown) around the chamber door 120.At this moment, said condenser and said doorframe defrosting pipe constitute condenser system together, and cold-producing medium is further imported the device for drying and filtering in downstream through the doorframe defrosting pipe after the condenser of flowing through.
Outlet at condenser is connected with device for drying and filtering, and is delivered to the capillary step-down behind the refrigerant liquid dry filter with middle temperature high pressure.The device for drying and filtering shell can be copper pipe, and the copper wire screen pack is equipped with at two ends, copper pipe the inside, and molecular sieve is equipped with in the centre.The effect of device for drying and filtering is the moisture in the absorbing refrigeration system, and is stifled to prevent ice, also plays a role in filtering simultaneously, and enterings capillary causes dirty blocking up to prevent impurity, mince etc.
In the refrigerant liquid of warm high pressure behind dry filter, be sent to capillary 131; And will be arranged in the warm gases at high pressure step-down gradually that discharge near the condenser of lower end at refrigerating plant 100 backs by capillary 131; And with the refrigerant liquid after the step-down (during near evaporimeter; Has had a spot of cold-producing medium to be gasified and be gas, thereby whole refrigerant fluid becomes gas liquid mixture) be transported to the evaporimeter that is positioned at the refrigerating chamber top.Because the heat conductivility of copper pipe is good, capillary 131 is that root hole footpath is very little, the copper tube of the long and polydisc round of length.Liquid refrigerant can receive bigger resistance during through capillary and produce pressure and fall (flow through conductor just as electric current, to produce voltage drop the same because of resistance), thereby has controlled the flow and the reasonable pressure differential that keeps condenser and evaporimeter of cold-producing medium.Capillary has two effects: (1) keeps between condenser cold-producing medium and the evaporator refrigerant certain pressure differential being arranged; Be condensed into liquid thereby in condenser, have higher pressure that refrigerant vapour is dispelled the heat in condenser, thereby guarantee that simultaneously refrigerant liquid has lower pressure that refrigerant liquid is absorbed heat and flashes to gas in evaporimeter in evaporimeter with the assurance refrigerant vapour; (2) flow of control cold-producing medium, if capillary resistance is big, refrigerant flow is little, and refrigerating capacity is few, and evaporating temperature is low; If capillary resistance is little, refrigerant flow is big, and refrigerating capacity is big, and evaporating temperature is high.
After this, the cold-producing medium through the capillary step-down is transported to the evaporimeter that is connected in the capillary other end.Evaporimeter is the cold parts of the product in the refrigerator refrigeration system, is commonly called as low-temperature receiver.The effect of evaporimeter is that evaporation under low pressure becomes gas by liquid after the cold-producing medium after the capillary step-down is getting in the evaporimeter thereby make.Because evaporation needs a large amount of heat, thereby passes through the heat in the evaporimeter respiratory box in this evaporation process, thereby reach the purpose of refrigeration.The evaporating temperature of evaporimeter inner refrigerant is low more, and then refrigeration is good more.
And then, the gaseous refrigerant of low temperature via muffler 132 from the evaporimeter that is positioned at the household freezer top and sent back to the compressor 20 that is positioned at freezer compartment floor.
That is to say,, after with refrigerant vapor compression, discharge high temperature, high pressure refrigerant vapor to the condenser that is connected in compressor 20 from compressor 20 according to the refrigerating plant of present embodiment.The transmission that said high temperature, high pressure refrigerant vapor are crossed heat at the condenser back warp, ambient air heat radiation, thereby make the refrigerant vapour cooling and be liquefied as in the liquid of warm high pressure, and export the device for drying and filtering in its downstream to.The capillary 131 that after device for drying and filtering is removed moisture and impurity etc., is sent to its downstream at refrigerant liquid carries out step-down, thus the liquid of warm low pressure in obtaining, and further be transported to evaporimeter.In evaporimeter, be evaporated to cryogenic gas through absorbing environmental (being the heat in the refrigerating chamber).And the gasiform cold-producing medium of low temperature is sent back to compressor 20 through muffler 132.
Wherein, in capillary 131, the liquid of cold-producing medium warm high pressure from input after step-down gradually in output becomes the liquid or the gas liquid mixture of warm low pressure.From helping improving the angle of refrigerating efficiency, be liquid in the perfect condition of output cold-producing medium, that is to say that the high more refrigeration of liquid proportion is good more in said gas liquid mixture.In order to improve the liquid proportion, can consider to increase the degree of supercooling of capillary 131, promptly capillary 131 is lowered the temperature through outside cooling.And in muffler 132, cold-producing medium is the extremely low cryogenic gas of temperature, if this part gas is directly delivered to compressor 20, then is a kind of great energy waste.Therefore; With capillary 131 with muffler 132 and put and form return-air heat exchange portion; Make between capillary 131 and the muffler 132 heat exchange takes place, utilize the cold of cold-producing medium in the muffler 132 to cool off the cold-producing medium in the capillary 131, can improve refrigerating efficiency, cut down the consumption of energy.
Particularly; In the present embodiment; Because the first return-air heat exchanging segment 130 is arranged on the rear side (being the left side among Fig. 1) of casing 110 and between said case courage 112 outer walls and said case shell 111 inwalls of refrigerating chamber 1 part; Therefore can utilize the cold of crossing of refrigerating chamber 1 inside part further to cool off capillary 131, thereby can further improve refrigerating efficiency, cut down the consumption of energy.Correspondingly; Refrigerating chamber 1 inside part is through temperature increases with capillary 131 heat exchange; Because the first return-air heat exchanging segment 130 crosses over whole freezing chamber district from bottom to up, so the crossing cold and also can be utilized effectively of refrigerating chamber 1 bottom part, so the whole temperature field in the refrigerating chamber 1 is more even.
In an example of the present invention, the said first return-air heat exchanging segment 130 is attached on case courage 112 outer walls of said refrigerating chamber 1 correspondence through the heat conduction adhesive tape.Thus, the whole temperature field of can further improve heat exchange efficiency between refrigerating chamber 1 inside part and the first return-air heat exchanging segment 130, more effectively improving in the refrigerating chamber 1 distributes, and further improves refrigerating efficiency, cuts down the consumption of energy.
In examples more of the present invention, as shown in Figures 2 and 3, the first return-air heat exchanging segment 130 forms corrugated.Thus, can increase effective heat exchange length of the first return-air heat exchanging segment 130 and refrigerating chamber 1, thereby improve heat exchange efficiency.Wherein, said corrugated promptly can be as shown in Figure 2 at horizontal Boulez, also can Boulez in the vertical as shown in Figure 3.
In another example of the present invention, as shown in Figure 4, the first return-air heat exchanging segment 130 by and the capillary put 131 coil a circle at least with muffler 132 and form.Thus, improve in the refrigerating chamber in the distribution requirements of temperature field satisfying, simple in structure, be convenient to install.
In another example of the present invention, as shown in Figure 1, also be limited with refrigerating chamber 2 in the case courage 112.Refrigerating chamber 2 and refrigerating chamber 1 adjacent setting.Correspondingly; Return-air heat exchange portion can also comprise the second return-air heat exchanging segment 140; The second return-air heat exchanging segment 140 is fixed on the case courage of refrigerating chamber part through the support (not shown), so that the case courage 112 of said second return-air heat exchanging segment 140 and refrigerating chamber 2 parts keeps certain intervals.According to this example, can further increase effective heat exchange length, thereby improve heat exchange efficiency.
