Below with reference to Fig. 1-Fig. 3, the heat pump 100 according to this utility model embodiment is described.Heat pump 100 is permissible For heat pump type air conditioning system.In the application explained below, carry out as a example by heat pump 100 is as heat pump type air conditioning system Explanation.Certainly, those skilled in the art are appreciated that heat pump 100 can also be for other type of heat pump System 100, and it is not limited to heat pump type air conditioning system.

As shown in Figure 1-Figure 3, according to the heat pump 100 such as heat pump type air conditioning system of this utility model embodiment, bag Include First Heat Exchanger the 1, second heat exchanger 2, compressor 3, control valve 4, gas-liquid separator 5, control device 6 and Throttling arrangement 9.

Compressor 3 has air entry 31 and air vent 32.Compressor 3 is for entering the coolant sucked from air entry 31 Row compression, and the coolant after compression is discharged from air vent 32.Further, at air entry 31, it is provided with reservoir 8, Reservoir 8 plays storage, gas-liquid separation, filtration, noise reduction and the effect of coolant buffering.

Control valve 4 has the first valve port the 41, second valve port the 42, the 3rd valve port 43 and the 4th valve port 44, the first valve port 41 are connected with the air vent 32 of compressor 3, and one end of the second valve port 42 and First Heat Exchanger 1 is (such as, in Fig. 1 Left end) be connected, the 3rd valve port 43 is connected with the air entry 31 of compressor 3, the 4th valve port 44 and the second heat exchanger One end (such as, the left end in Fig. 1) of 2 is connected.When one of them in the first valve port 41 and the 3rd valve port 43 with When second valve port 42 connects, the first valve port 41 connects with the 4th valve port 44 with another in the 3rd valve port 43, i.e. when When first valve port 41 connects with the second valve port 42, the 3rd valve port 43 connects with the 4th valve port 44, and when the 3rd valve port 43 When connecting with the second valve port 42, the first valve port 41 connects with the 4th valve port 44, to realize the effect of commutation.Alternatively, Control valve 4 is cross valve, but is not limited to this.

Gas-liquid separator 5 has the first connector 51 (or being the form of one section of first connecting tube), the second connector 52 (or being the form of one section of second connecting tube) and outlet 53 (or the form for one section outlet 53 pipe), outlet 53 are connected with air entry 31, to discharge isolated gaseous coolant.Such as, in the example of Fig. 1-Fig. 3, first Connector 51 and the second connector 52 are formed at the bottom of gas-liquid separator 5 with being spaced apart from each other, and outlet 53 is formed at The top of gas-liquid separator 5, thus, it is simple to liquid refrigerants flows out from the second connector 52, and facilitates isolated Gaseous coolant is discharged from the outlet 53 at top.

Control device 6 and include that the first control mouth 61, second controls mouth the 62, the 3rd and controls mouth 63 and the 4th control mouth 64, First controls mouth 61 is connected with the first connector 51, and (such as, second control the other end of mouth 62 and the second heat exchanger 2 Right-hand member in Fig. 1) it is connected, the 3rd controls mouth 63 is connected with the second connector 52, and the 4th controls mouth 64 changes with first The other end (such as, the right-hand member in Fig. 1) of hot device 1 is connected.When first controls in mouth 61 and the 3rd control mouth 63 One of them control when mouth 62 connects first with second and control mouth 61 and the 3rd and control another in mouth 63 with the 4th Control mouth 64 to connect, i.e. control the 3rd control mouth 63 and the 4th control when mouth 61 connects with the second control mouth 62 when first Donsole 64 connects, and when the 3rd controls first to control mouth 61 and the 4th control when mouth 63 connects with the second control mouth 62 Mouth 64 connection, to realize the effect of commutation.Alternatively, controlling device 6 is cross valve, but is not limited to this.

Throttling arrangement 9 is connected to control the first control mouth 61 and the first connector 51 of gas-liquid separator 5 of device 6 Between, now throttling arrangement 9 is always positioned at the upstream of gas-liquid separator 5, from regardless of whether coolant is from First Heat Exchanger 1 Flow to gas-liquid separator 5, or flow to gas-liquid separator 5 from the second heat exchanger 2, on the flow direction of coolant, joint Stream device 9 is respectively positioned on the upstream of gas-liquid separator 5, thus the coolant entering into gas-liquid separator 5 plays throttling fall The effect of pressure.

Further, it is provided with dropping equipment 7 at the outlet 53 of gas-liquid separator 5.Alternatively, dropping equipment 7 is fall Pressure valve, but it is not limited to this.

When heat pump 100 refrigerating operaton, as in figure 2 it is shown, control the first control mouth 61 and the 4th control of device 6 Donsole 64 connects and the 3rd control mouth 63 controls mouth 62 with second and connects, the high-pressure gaseous coolant that compressor 3 is discharged Enter First Heat Exchanger 1 and be cooled to supercooled liquid coolant, control by controlling the 4th control mouth 64 and first of device 6 Mouth 61 enters gas-liquid separator 5 by the first connector 51 after entering throttling arrangement 9 decrease temperature and pressure, is now divided by gas-liquid The second connector 52 coolant out from device 5 controls mouth 62 by controlling the 3rd control mouth 63 and second of device 6 Enter and become overheated gaseous coolant after the second heat exchanger 2 absorbs heat and return to reservoir 8, and going out by gas-liquid separator 5 Mouthful 53 coolant out then return to reservoir 8 by after dropping valve blood pressure lowering, exist with from the second heat exchanger 2 coolant out Again become high-pressure gaseous coolant entrance First Heat Exchanger 1 after jointly being compressed by compressor 3 after reservoir 8 mixing to cool down Become supercooled liquid coolant, so circulate, to constitute kind of refrigeration cycle.

When heat pump 100 heating operation, as it is shown on figure 3, the first control mouth 61 and second of control valve 4 controls Mouth 62 connection and the 3rd controls mouth 63 and connects with the 4th control mouth 64, and the high-pressure gaseous coolant that compressor 3 is discharged enters Enter the second heat exchanger 2 and be cooled to supercooled liquid coolant, control mouth by controlling the second control mouth 62 and first of device 6 Gas-liquid separator 5 is entered, now by gas-liquid separator by the first connector 51 after 61 entrance throttling arrangement 9 decrease temperature and pressure Second connector 52 of 5 coolant out is entered by the 3rd control mouth 63 and the 4th control mouth 64 controlling device 6 First Heat Exchanger 1 becomes overheated gaseous coolant and returns to reservoir 8 after absorbing heat, and by the outlet of gas-liquid separator 5 53 coolant out then by returning to reservoir 8 after dropping valve blood pressure lowering, with from First Heat Exchanger 1 coolant out in storage Again become high-pressure gaseous coolant after jointly being compressed by compressor 3 after liquid device 8 mixing to enter the second heat exchanger 2 and be cooled to Supercooled liquid coolant, so circulates, and heats circulation to constitute.

Thus, when heat pump 100 such as heat pump type air conditioning system refrigeration and heating operation, all can be by the gaseous state after throttling Coolant is separated, thus in refrigeration with all can promote vaporizer during heating operation and (such as, second change during refrigerating operaton Hot device 2 is vaporizer) exchange capability of heat, and reduce the pressure loss of vaporizer, reach to promote heat pump 100 example Purpose such as heat pump type air conditioning system operational efficiency.

Heat pump 100 such as heat pump type air conditioning system according to this utility model embodiment, by arranging control device 6 With throttling arrangement 9, the operational efficiency of heat pump 100 such as heat pump type air conditioning system can be promoted.

According to alternative embodiments more of the present utility model, throttling arrangement 9 can be that flow keeps constant throttling arrangement 9. Still optionally further, throttling arrangement 9 is capillary tube, but is not limited to this.Thus, it is possible to effectively reduce heat pump 100 Cost.

Other of heat pump 100 according to this utility model embodiment constitute and operate for those of ordinary skill in the art For be all known, be not detailed herein.
