Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the principle schematic according to variable volume compressor of the present utility model;
Description of reference numerals:
10, the first solenoid valve; 20, the second solenoid valve; 31, inhalation temperature detection device; 32, exhaust temperature detection means; 33, middle pressure temperature-detecting device; 40, control gear.
Embodiment
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, according to variable volume compressor of the present utility model, comprise intakeport, relief opening and middle pressure mouth, relief opening is connected by the first pipeline with middle pressure mouth, intakeport is connected by the second pipeline with middle pressure mouth, first pipeline is arranged in series the first solenoid valve 10, second pipeline has been arranged in series the second solenoid valve 20, variable volume compressor also comprise corresponding with intakeport arrange inhalation temperature detection device 31, with the corresponding exhaust temperature detection means 32 that arranges of relief opening with press temperature-detecting device 33 in arranging with middle pressure mouth is corresponding.The utility model is by arranging inhalation temperature detection device, exhaust temperature detection means and middle pressure temperature-detecting device respectively, to the temperature detection of intakeport, relief opening and middle pressure mouth, thus can judge according to the temperature detected whether the first solenoid valve 10 and the second solenoid valve 20 normally are opened or closedown, and then the whether reversal connection of the first solenoid valve and the second solenoid valve can be judged.
Usually, inhalation temperature detection device 31, exhaust temperature detection means 32 and middle pressure temperature-detecting device 33 are temperature-sensitive bag, on the pipeline that the setting of temperature-sensitive bag correspondence is connected with intakeport, relief opening and middle pressure mouth, thus measure the refrigerant temperature of relevant position.
Preferably, variable volume compressor also comprises the control gear 40 that the temperature detected respectively according to inhalation temperature detection device 31, exhaust temperature detection means 32 and middle pressure temperature-detecting device 33 controls the first solenoid valve 10 and the second solenoid valve 20, control gear 40 can according to the contrast of three's temperature, thus the whether reversal connection of the first solenoid valve 10 and the second solenoid valve 20 can be judged, when reversal connection, by contrary control, the normal unlatching of the first solenoid valve 10 and the second solenoid valve 20 can be realized.
Composition graphs 1 illustrates variable volume compressor controlling method of the present utility model.Particularly, open when control gear 40 sends the first solenoid valve 10, after the control signal that the second solenoid valve 20 cuts out, detect inhalation temperature Ts, the delivery temperature Td of intakeport, relief opening and middle pressure mouth correspondence and middle pressure temperature Tm respectively and contrast; Work as Tm=Td>Ts, judge that the first solenoid valve 10 is normally opened, the second solenoid valve 20 normally cuts out; Work as Tm=Ts<Td, control gear 40 sends the first solenoid valve 10 and cuts out, the control signal that second solenoid valve 20 is opened, namely Tm=Ts<Td is worked as, then can judge the first solenoid valve 10 and the second solenoid valve 20 reversal connection, by the Reverse Turning Control of control gear 40, thus unit is normally worked.
Similarly, close when control gear 40 sends the first solenoid valve 10, after the control signal that the second solenoid valve 20 is opened, detect inhalation temperature Ts, the delivery temperature Td of intakeport, relief opening and middle pressure mouth correspondence and middle pressure temperature Tm respectively and contrast; Work as Tm=Ts<Td, judge that the first solenoid valve 10 normally cuts out, the second solenoid valve 20 is normally opened; Work as Tm=Td>Ts, control gear 40 sends the first solenoid valve 10 and opens, the control signal that second solenoid valve 20 cuts out, namely Tm=Td>Ts is worked as, then can judge the first solenoid valve 10 and the second solenoid valve 20 reversal connection, by the Reverse Turning Control of control gear 40, thus unit is normally worked.
In addition, when control gear 40 detects the first solenoid valve 10 and the second solenoid valve 20 reversal connection, control gear 40 sends failure warning, reminds solenoid valve 1 and solenoid valve 2 coil to connect instead, and after artificial eliminating, unit normally runs, and no longer carries out failure warning.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
According to variable volume compressor of the present utility model, by arranging inhalation temperature detection device, exhaust temperature detection means and middle pressure temperature-detecting device respectively, to the temperature detection of intakeport, relief opening and middle pressure mouth, thus can judge according to the temperature detected whether the first solenoid valve and the second solenoid valve are normally opened or close, and then the whether reversal connection of the first solenoid valve and the second solenoid valve can be judged.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
