As Figure 1-Figure 2, according to the refrigerator 100 of the utility model embodiment, compressor 1, condenser 2, evaporimeter 3, anti-condensation pipe 5, bypass circulation 8 and control valve assembly can be comprised.
Particularly, compressor 1 has exhaust outlet A and gas returning port B, and it is inner that refrigerant enters into compressor 1 from gas returning port B, and after compressor 1 compresses, form the refrigerant of HTHP, and discharge from exhaust outlet A.Wherein, it should be noted that, other structure of compressor 1 has been prior art, is no longer described in detail herein.
The first end of condenser 2 (such as, left end shown in Fig. 1 with Fig. 2) be connected with exhaust outlet A, thus the refrigerant being convenient to discharge from the exhaust outlet A of compressor 1 flows into condenser 2, and carry out heat exchange with the surrounding environment residing for refrigerator 100 in condenser 2.
The first end of evaporimeter 3 (such as, right-hand member shown in Fig. 1 and Fig. 2) with the second end of condenser 2 (such as, right-hand member shown in Fig. 1 and Fig. 2) between be in series with throttling arrangement 4, and the second end of evaporimeter 3 (left end such as, shown in Fig. 1 with Fig. 2) is connected with gas returning port B.Thus, when refrigerator 100 provides cold by room between in compressor 1 pair of refrigerator 100, the refrigerant flowed out from condenser 2 can flow to throttling arrangement 4, and under the reducing pressure by regulating flow effect of throttling arrangement 4, form the liquid refrigerants of low-temp low-pressure, refrigerant flows out from throttling arrangement 4 and flows to evaporimeter 3 subsequently, environment indoor in evaporimeter 3 and between refrigerator 100 carries out heat exchange, provides cold with room between giving, thus between being convenient to pair, indoor food refrigerates or freezing.
Anti-condensation pipe 5 is connected between the second end of condenser 2 and throttling arrangement 4, and anti-condensation pipe 5 can be arranged on the doorframe of refrigerator 100.Thus, the refrigerant of HTHP flowed out from condenser 2 can flow in the anti-condensation pipe 5 that is arranged on refrigerator 100 doorframe, in case the position such as the doorframe of stagnant ice case 100 or door seal produces condensation, improves the reliability that refrigerator 100 uses.

Specifically, such as, as shown in Figure 1, when needs carry out anti-condensation to refrigerator 100, refrigerant after compressor 1 compresses is discharged to condenser 2 to carry out heat exchange with the surrounding environment residing for refrigerator 100 from exhaust outlet A, refrigerant after heat exchange flows to anti-condensation pipe 5 under the control of control valve assembly, in case the position such as the door seal of stagnant ice case 100 or doorframe produces condensation, refrigerant flows to throttling arrangement 4 subsequently, the liquid refrigerants of low-temp low-pressure is formed after throttling arrangement 4 reducing pressure by regulating flow, and flow to evaporimeter 3, environment indoor in evaporimeter 3 and between refrigerator 100 carries out heat exchange, cold is provided with room between giving, refrigerant after heat exchange flows out from evaporimeter 3, and turn back to compressor 1 by gas returning port B, reciprocal with this.Thus, the positions such as the door seal of refrigerator 100 or doorframe can be avoided to produce condensation.
Again such as, as shown in Figure 2, when without the need to carrying out anti-condensation to refrigerator 100, the refrigerant of the HTHP now after compressor 1 compresses is discharged to condenser 2 from exhaust outlet A, and exchange heat is carried out with the surrounding environment residing for refrigerator 100 in condenser 2, refrigerant is under the control of control valve assembly subsequently, bypass circulation 8 is flowed to from the second end of condenser 2, then throttling arrangement 4 is flowed to, and after throttling arrangement 4 reducing pressure by regulating flow, form the liquid refrigerants of low-temp low-pressure, and enter in evaporimeter 3 to provide cold to room between in refrigerator 100, after refrigerant flows out from evaporimeter 3, compressor 1 is turned back to through the gas returning port B of compressor 1, form circulation.Thus, the heat in anti-condensation pipe 5 effectively can be avoided to enter in refrigerator 100, reduce the thermic load of refrigerator 100 to a certain extent, reduce the energy consumption of refrigerator 100.
According to the refrigerator 100 of the utility model embodiment, by anti-condensation pipe 5 is connected between the second end of condenser 2 and throttling arrangement 4, and bypass circulation 8 and anti-condensation pipe 5 are connected in parallel, utilize control valve assembly to be connected with anti-condensation pipe 5 with the second end of condenser 2, bypass circulation 8 respectively simultaneously and flow to bypass circulation 8 or anti-condensation pipe 5 with the refrigerant controlling to flow out from condenser 2, not only can play the anti-condensation effect to refrigerator 100, the thermic load of refrigerator 100 can also be reduced to a certain extent, reduce the energy consumption of refrigerator 100.
