[0026] Reference below Figure 1-Figure 3 A heating and cooling type air conditioner 100 according to an embodiment of the present invention is described. Specifically, the heating and cooling type air conditioner 100 is an inverter air conditioner.
[0027] Such as figure 1 As shown, the heating and cooling type air conditioner 100 according to the embodiment of the present invention includes: a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, an electronic control system, a first throttle element 5, an indoor heat exchanger 6, a single The direction valve 7, the second throttling element 8 with regulating function and the controller. Among them, the compressor 1 has an exhaust port 10 and an intake port 11. It should be noted that the structure and working principle of the compressor 1 are all existing technologies, and will not be described in detail here. The four-way valve 2 includes a first valve port a, a second valve port b, a third valve port c, and a fourth valve port d. The first valve port a is connected to the exhaust port 10, and the second valve port b is connected to the suction port. 11 connected.
[0028] One end of the outdoor heat exchanger 3 is connected to the third valve port c. The electronic control system includes an electronic control module and an electronic control radiator 4. The electronic control radiator 4 has a refrigerant channel 40, one end of the refrigerant channel 40 is connected to the other end of the outdoor heat exchanger 3, and the electronic control radiator 4 is adjacent to the electronic control module Set to absorb heat and cool down the electronic control module.
[0029] The first throttle element 5 is connected to the other end of the refrigerant channel 40. Optionally, the first throttle element 5 is a capillary tube. The two ends of the indoor heat exchanger 6 are respectively connected with the first throttle element 5 and the fourth valve port d. The one-way valve 7 is respectively connected to the other end of the outdoor heat exchanger 3 and the first throttling element 5. That is to say, the one-way valve 7 and the electric control radiator 4 are connected in parallel to the other end and the first end of the outdoor heat exchanger 3 Between the throttle elements 5, the one-way valve 7 is unidirectionally communicated in the direction from the first throttle element 5 to the other end of the outdoor heat exchanger 3, that is, the one-way valve 7 is in the direction from the outdoor heat exchanger The other end of 3 does not conduct in the direction from the first throttle element 5.
[0030] The second throttling element 8 is connected in series between the other end of the outdoor heat exchanger 3 and the electronic control radiator 4. The second throttling element 8 can throttle the refrigerant entering the electronic control radiator 4 to further Reduce the temperature of the refrigerant entering the electronically controlled radiator 4, where the second throttling element 8 has an adjustment function, and the second throttling element 8 adjusts the throttling effect on the refrigerant while adjusting the flow rate of the refrigerant, namely The temperature of the refrigerant discharged from the second throttle element 8 is adjusted. The controller controls the second throttle element 8 to adjust the flow rate of the refrigerant entering the electronically controlled radiator 4. Among them, it should be noted that the second throttling element 8 can be any device as long as it can adjust the flow rate of the refrigerant entering the electronically controlled radiator 4 and throttle the refrigerant entering the electronically controlled radiator 4. In addition, the controller may be an electric control module in the heating and cooling air conditioner 100, and the controller may also be a separate control module. In some examples of the present invention, the second throttle element 8 is an electronic expansion valve.
[0031] When the heating and cooling type air conditioner 100 is in cooling operation, the first valve port a and the third valve port c of the four-way valve 2 are in conduction, and the fourth valve port d and the second valve port b are in conduction, such as figure 1 As shown by the solid arrow in the arrow, the refrigerant discharged from the exhaust port 10 of the compressor 1 is discharged into the outdoor heat exchanger 3 through the four-way valve 2. The refrigerant is condensed in the outdoor heat exchanger 3 to dissipate heat, and passes through the condensation The temperature of the radiating refrigerant is reduced to close to or slightly higher than the outdoor ambient temperature. At this time, since the one-way valve 7 does not conduct in the direction from the outdoor heat exchanger 3 to the first throttle element 5, the refrigerant discharged from the outdoor heat exchanger 3 first passes through the second throttle element 8 before being throttled. The refrigerant entering the electronic control radiator 4 absorbs heat and reduces the temperature of the electronic control module, and then the refrigerant is discharged from the electronic control radiator 4 and flows into the first throttle element 5. Throttling, the refrigerant discharged from the first throttling element 5 enters the indoor heat exchanger 6 to absorb heat and reduce the temperature of the room used, and finally the refrigerant discharged from the indoor heat exchanger 6 passes through the four-way valve 2 and suction in turn The port 11 returns to the compressor 1, thereby completing the refrigeration cycle.
[0032] Among them, the flow rate of the refrigerant entering the electronic control radiator 4 can be adjusted by the second throttle element 8, so that the temperature of the refrigerant entering the electronic control radiator 4 can be adjusted so that the temperature of the electronic control module is always at Within a reasonable range, while cooling the electronic control module, it avoids the generation of condensation, enhances the reliability of the electronic control module, and achieves the dual purpose of cooling the electronic control module and ensuring the safety of the electronic control module. Moreover, in the refrigeration cycle, since the refrigerant passes through the electronic control radiator 4, the flow rate is relatively large, which can effectively and continuously achieve the purpose of cooling the electronic control module.
[0033] When the heating and cooling type air conditioner 100 is in heating operation, the first valve port a and the fourth valve port d of the four-way valve 2 are connected, and the third valve port c and the second valve port b are connected, such as figure 1 As shown by the dotted arrow, the refrigerant discharged from the exhaust port 10 of the compressor 1 is discharged into the indoor heat exchanger 6 through the four-way valve 2. The refrigerant is condensed in the indoor heat exchanger 6 to dissipate heat to the room The heat is released and the temperature rises. The refrigerant discharged from the indoor heat exchanger 6 enters the first throttling element 5 for throttling. At this time, the one-way valve 7 is moving from the first throttling element 5 to the outdoor heat exchanger 3 In the direction of unidirectional conduction, since the fluid resistance in the one-way valve 7 is less than the fluid resistance in the electronic control radiator 4, most of the refrigerant flowing out of the first throttle element 5 is discharged to the outdoor through the one-way valve 7 for heat exchange The evaporative heat absorption in the device 3 reduces the outdoor ambient temperature, and finally the refrigerant discharged from the outdoor heat exchanger 3 is discharged back into the compressor 1 through the four-way valve 2 and the suction port 11 in turn, completing the heating cycle.
[0034] When the heating and cooling type air conditioner 100 is in heating operation, the outdoor environment temperature is low. At this time, there is little or no refrigerant in the heating cycle passing through the electronic control radiator 4 to prevent low-temperature refrigerant from affecting the electronic control module. Too low a temperature drop can ensure the reliability of the electric control module of the heating and cooling air conditioner 100 during heating operation.
[0035] According to the heating and cooling type air conditioner 100 of the embodiment of the present invention, the one-way valve 7 and the electronically controlled radiator 4 are connected in parallel between the outdoor heat exchanger 3 and the first throttle element 5, and the one-way valve 7 is in the first section. The flow element 5 is unidirectionally conducted in the direction of the outdoor heat exchanger 3. During the refrigeration cycle, the refrigerant discharged from the outdoor heat exchanger 3 at a temperature close to or slightly higher than the outdoor ambient temperature enters the electronically controlled radiator 4 The electronic control module absorbs heat and cools, and the refrigerant in the refrigeration cycle has been passed through the electronic control radiator 4, which not only ensures a good cooling effect on the electronic control module, but also solves the effect of condensation on the electronic control The reliability of the module. During the heating cycle, most of the refrigerant discharged from the first throttle element 5 is discharged into the outdoor heat exchanger 3 through the one-way valve 7, thereby preventing the low-temperature refrigerant from lowering the temperature of the electronic control module too low , Which can ensure the reliability of the electric control module of the heating and cooling air conditioner 100 during heating operation.

The temperature detecting device 9 is connected to the controller, and the controller controls according to the result of the temperature detecting device 9. The second throttle element 8 adjusts the flow rate of the refrigerant. Therefore, by providing the temperature detection device 9, the temperature of the refrigerant entering the electronic control radiator 4 can be adjusted according to the temperature of the electronic control module detected by the temperature detection device 9, further ensuring the safety of the electronic control module. Optionally, the temperature detection device 9 is a temperature sensor.
[0037] In some examples of the present invention, such as figure 2 As shown, the temperature detection device 9 is arranged on the side wall of the electronic control radiator 4 adjacent to the electronic control module. Of course, the present invention is not limited to this, and the temperature detection device 9 can also be provided on the electronic control module or other locations where the temperature of the electronic control module can be detected.

Optionally, the metal tube 42 is a copper tube or an aluminum tube . Thus, the structure of the electronically controlled radiator 4 is simple. In some other embodiments of the present invention, the containing groove 412 may be provided on the outer surface of the heat dissipation shell 41, that is, the metal tube 42 is embedded on the outer surface of the heat dissipation shell 41 at this time. In some specific examples of the present invention, such as figure 2 with image 3 As shown, the metal tube 42 is formed as a "U"-shaped tube, and the containing groove 412 is formed as a "U"-shaped groove. Of course, the present invention is not limited to this, and the metal pipe 42 and the containing groove 412 can also be formed in other shapes. For example, the metal pipe 42 can be serpentinely arranged in the containing groove 412. At the same time, the shape of the heat dissipation shell 41 is not specifically limited. Figure 1-Figure 3 In the example shown, the heat dissipation case 41 is formed in a rectangular shape.
[0039] Such as figure 2 with image 3 As shown, in a further embodiment of the present invention, the heat dissipation shell 41 includes a heat dissipation base 410 and a cover plate 411, wherein the heat dissipation base 410 is disposed adjacent to the electronic control module to ensure that the refrigerant in the metal tube 42 can be exchanged with the electronic control module Thermally, a first groove 413 is provided on the heat dissipation base 410. The cover plate 411 is provided with a second groove 414, the cover plate 411 is provided on the heat dissipation base 410, and the first groove 413 and the second groove 414 cooperate to define a receiving groove 412.
