The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 4 is the sketch of the refrigeration system of Refrigeator with dual condenser of the present invention.Fig. 5 is the state diagram that is provided with that the refrigerator refrigeration system constitutes among Fig. 4.Fig. 6 is the unfolding state figure of body among Fig. 5.As shown in the figure, Refrigeator with dual condenser of the present invention comprises and is formed with the forwards refrigerating chamber 13 and the refrigerating chamber 15 of opening, the rearward body 11 of the Machine Room 17 of opening separately; The compressor 21 of compression refrigerant is located at 17 inside, Machine Room; Condenser 23 is located at inner compressor 21 1 sides of Machine Room 17, to compressed refrigerant heat release; Be interconnected the metal tube 19 that embeds along with the front openings of refrigerating chamber 13 and refrigerating chamber 15 with the outflow side of condenser 23; The inflow side is interconnected in the outflow side of condenser 23, is embedded in the post-condenser 27 of inside of the rear wall of body 11; The evaporimeter 31 that carries out cooling effect is arranged at the rear of refrigerating chamber 13; For the flow direction of refrigerant, capillary 29 is arranged at evaporimeter 31 upstream sides; The valve 33 that opens and closes path is arranged at the inflow side of post-condenser 27; Condensation temperature detecting sensor 37 is arranged at capillary 29 upper reaches portions, detects refrigerant temperature; Testing result with condensation temperature detecting sensor 37 is a benchmark, and control part 35 is set, the switching of by-pass valve control 33.
Be formed with refrigerating chamber 13 and refrigerating chamber 15 to open front separately in the inside of body 11, it becomes dividing plate 12 is arranged with the upper and lower synform, and a side is provided with control part 35 on body 11, and controllable valve door 33 opens and closes and driver parts.At the rear of body 11 Machine Room 17 of opening is rearward arranged, inside one side of Machine Room 17 has the compressor 21 of compressible refrigerant.In a side of body 11, in order to suck the refrigerant of compression body state, be provided with fluid reservoir 22, in order to make compressed refrigerant heat release, the discharge side of compressor 21, the connection that has condenser 23 to be interconnected.In order to promote the heat release of refrigerant,, be provided with air-supply electric fan 25 to condenser 23 air-supplies in a side of condenser 23.In order to suppress to form the dew phenomenon, at the connecting portion of the front openings of refrigerating chamber 13 and refrigerating chamber 15, embed metal tube 19 is installed, condenser 23 connects the inflow side of post-condenser 27 in the outflow side, above-below direction embeds and is installed on body 11 rear walls, and the ordering shape is arranged.
In post-condenser 27 inflow sides,, be provided with to open and close valve 33 for the refrigerant that cuts off to post-condenser 27 flows into.When being lower than institute's fixed temperature for condensation temperature at refrigerant, cut-out flows into to the refrigerant of post-condenser 27, when condensation temperature is higher than institute's fixed temperature, increases in order to make thermal discharge, make refrigerant flow into, open and close valve 33 and link to each other with control part 35 electricity consumptions that control opens and closes valve 33 to post-condenser 27.
In these cases, in case compressor 21 drives, control part 35 will be a benchmark with the detected temperatures that detects in condensation temperature detecting sensor 37, when condensation temperature was higher than institute's fixed temperature, control opened and closed valve 33, and refrigerant is flowed into to post-condenser 27, refrigerant by compressor 21 compressions flow to metal tube 19 and post-condenser 27 separately via condenser 23, condensation after the heat release before flowing into capillary 29, is collaborated mutually and is flowed into capillary 29.Refrigerant is inflow evaporator 31 after passing through capillary 29 puffings, and the latent heat around the refrigerant of inflow evaporator 31 will absorb carries out evaporative cooling.The refrigerant that cools off will flow into fluid reservoir 22.In fluid reservoir 22, the refrigerant of gaseous state will be sucked by compressor 21 again, finishes cooling in the circulatory system repeatedly.
According to the testing result of condensation temperature detecting sensor 37, when the condensation temperature of refrigerant was lower than institute's fixed temperature, in order to prevent the excessive heat release of refrigerant, control part 35 controls opened and closed valve 33, cut off refrigerant and flow into post-condenser 27.
As mentioned above, the dividing plate that forms with direction up and down is interval, forms the refrigerator that refrigerating chamber and refrigerating chamber constitute, and still, it is the interval that the present invention also is suitable for the dividing plate that forms with horizontal direction certainly, the refrigerator that refrigerating chamber that is formed by the downside that makes progress and refrigerating chamber constitute.
Inflow side at post-condenser more than has been described, the situation of the switching valve that opens and closes the post-condenser path is set, but in fact, also 3 phase valves can be set in the bifurcation of metal tube and post-condenser, make when condensation temperature is lower than first temperature, control part order 3 phase valves, cut off the refrigerant that flows into post-condenser, when condensation temperature is higher than second temperature, make metal tube and post-condenser all open, condensation temperature is between first temperature and second temperature time, makes a mutual opening among metal tube and the post-condenser.
