Abstract
The utility model relates to an adjusting structure for the compression ratio of a compressor, which is used for an air conditioner and a water heating machine group of a heat pump. A heat exchanger (7) is provided with a cooling medium inlet pipe (3), a cooling medium outlet pipe (4), a water outlet pipe (5) and a water inlet pipe (6); a condensing pressure adjusting water valve (1) is arranged on the water inlet pipe (6), wherein the condensing pressure adjusting water valve (1) is connected in parallel with a by-pass water valve (2). As the utility model adopts the structure that the condensing pressure adjusting water valve is connected in parallel with the by-pass water valve, the condition that the pressure of the low pressure of a system drops and the pressure of high pressure is unchanged because of changes of external conditions, which leads that the compression ratio of the system is increased is prevented; a compressor is ensured to always run within a rational and normal compression ratio range, the normal running of the compressor can be ensured and an air conditioner system is made to stably run. The adjusting structure for the compression ratio of a compressor of the utility model has the advantages of reasonable design, economy, practicality and convenient control.
Description
1, technical field:
The utility model is a kind of structure that is used for the adjusting compressor pressure ratios of air-conditioner and heat pump water-heating machine, belongs to the renovation technique of regulating the used structure of compressor pressure ratios in air-conditioner and the heat pump water-heating machine.
2, background technology:
In traditional air-conditioning and heat pump water-heating machine system, if environment temperature changes, system operational parameters (high and low pressure lateral pressure, temperature) also changes thereupon, in any case change, it then should be limited that the compression ratio of compressor changes, and should be in certain zone of reasonableness.But since affected by environment, when the refrigerant low-pressure lateral pressure descends, because of the effect of condensation pressure regulation water valve, the refrigerant high side pressure remains unchanged, the compression ratio of compressor can increase like this, so that influence the service life of compressor, even compressor can not be run well.
3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and provides a kind of compression ratio of compressor that makes to maintain in the reasonable range, guarantees that compressor runs well, and makes the adjustment structure of the compressor pressure ratios of air-conditioning and heat pump water-heating machine system stable operation.
Structural representation of the present utility model as shown in drawings, heat exchanger (7) is provided with refrigerant inlet pipe (3), refrigerant goes out pipe (4) and outlet pipeline (5), inlet pipeline (6), condensation pressure regulation water valve (1) is installed on the inlet pipeline (6), wherein condensation pressure regulation water valve (1) and be connected to bypass water valve (2).
Above-mentioned bypass water valve (2) is a magnetic valve.
Above-mentioned heat exchanger (7) is plate type heat exchanger or pipe heat exchanger.
The utility model is owing to adopt on condensation pressure regulation water valve and be connected to the structure of bypass water valve, so prevented that the constant system compresses that causes of high-pressure is than increasing because the external condition variation causes system low-voltage pressure to reduce, guaranteed that compressor maintains running in reasonable, the normal compression ratio range all the time, the assurance compressor runs well, make air-conditioning and heat pump water-heating machine system stable operation, the utility model is a kind of reasonable in design, both economical and practical, control the adjustment structure of compressor pressure ratios easily again.
4, description of drawings:
Fig. 1 is a structural representation of the present utility model.
5, the specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, heat exchanger (7) is provided with refrigerant inlet pipe (3), refrigerant goes out pipe (4) and outlet pipeline (5), inlet pipeline (6), condensation pressure regulation water valve (1) is installed on the inlet pipeline (6), wherein condensation pressure regulation water valve (1) and be connected to bypass water valve (2).In the present embodiment, regulate for convenient, above-mentioned bypass water valve (2) is a magnetic valve.
Above-mentioned heat exchanger (7) can be plate type heat exchanger or pipe heat exchanger.In the present embodiment, heat exchanger (7) is a plate type heat exchanger.
When the utility model uses in air-conditioning or heat pump water-heating machine system, when refrigerant low-pressure lateral pressure reduces, pressure in the condensation pressure regulation water valve (1) still remains unchanged, in order to make the refrigerant high-pressure that to a certain degree decline be arranged, prevent that compression ratio is bigger than normal, to measure low pressure low to a certain degree the time when receptor, system gives (2) signals of bypass water valve, bypass water valve (2) is opened, the discharge that enters heat exchanger (1) increases, and the high-pressure of system reduces, the pressure signal that senses by receptor, constantly regulate the size of inflow, the ratio of high pressure and low pressure is maintained in certain scope.
Claims (3)
1, a kind of adjustment structure of compressor pressure ratios, heat exchanger (7) is provided with refrigerant inlet pipe (3), refrigerant goes out pipe (4) and outlet pipeline (5), inlet pipeline (6), condensation pressure regulation water valve (1) is installed on the inlet pipeline (6), it is characterized in that condensation pressure regulation water valve (1) and is connected to bypass water valve (2).
2, the adjustment structure of compressor pressure ratios according to claim 1 is characterized in that above-mentioned bypass water valve (2) is a magnetic valve.
3, the adjustment structure of compressor pressure ratios according to claim 1 and 2 is characterized in that above-mentioned heat exchanger (7) is plate type heat exchanger or pipe heat exchanger.
