Description

Technical field:

[0001] The invention relates to the technical field of compressor refrigeration, and in particular to an integrated refrigerator and air conditioner with a shared compressor. Background technology:

[0002] At present, in daily life, refrigerators and air conditioners are independent household appliances, each of which requires a separate compressor for refrigeration. This not only requires a large amount of space to place the appliances, but also consumes a lot of energy and has a heavy load, which is not conducive to energy conservation and emission reduction.

[0003] Most of the existing refrigerator-air conditioner integrated machines are for home use, and blow out the cold air in the refrigerator to be used as an air conditioner. The integrated air conditioner and refrigerator with the Chinese patent authorization announcement number CN 215597581 U discloses a technical solution combining an air conditioner and a refrigerator. However, in this solution, although the air conditioner body and the refrigerator body are integrated together to reduce the occupied space, two independent compressors are used to perform the air conditioning refrigeration function and the refrigerator refrigeration function respectively, which still generates a large energy consumption.

[0004] In view of this, the inventor proposes the following technical solution. Summary of the invention:

[0005] The object of the present invention is to overcome the deficiencies of the prior art and provide an integrated refrigerator and air conditioner with a shared compressor.

[0006] In order to solve the above technical problems, the present invention adopts the following first technical solution: a refrigerator-air-conditioning integrated machine with a shared compressor, comprising: a compressor, a refrigeration cooler, an air-conditioning evaporator, a refrigerator evaporator, a four-way reversing valve, and a three-way valve, wherein one end of the refrigeration cooler, the air-conditioning evaporator, and the refrigerator evaporator are arranged in parallel through the three-way valve, and the other end of the refrigeration cooler, the air-conditioning evaporator, and the refrigerator evaporator The four-way reversing valve is connected to the compressor; a first throttle valve is arranged between the air-conditioning evaporator and the three-way valve, and a second throttle valve is respectively arranged between the refrigerator evaporator and the three-way valve.

[0007] Furthermore, in the above technical solution, a second circuit is provided between the refrigeration device and the four-way reversing valve to connect the refrigerator evaporator, a first switch is provided on the second circuit, and a second switch is provided between the refrigerator evaporator and the air conditioner evaporator and the four-way reversing valve.

[0008] Furthermore, in the above technical solution, the four-way reversing valve includes a first interface and a third interface respectively connected to the inlet and outlet of the compressor, a second interface connected to the refrigeration unit, and a fourth interface simultaneously connected to the air-conditioning evaporator and the refrigerator evaporator, wherein the second switch is located between the fourth interface and the air-conditioning evaporator and the refrigerator evaporator to facilitate disconnection between the refrigerator evaporator and the fourth interface without blocking the connection between the fourth interface and the air-conditioning evaporator.

[0009] Furthermore, in the above technical solution, one end of the second circuit is connected between the refrigerator evaporator and the second switch, and the other end of the second circuit is connected between the refrigeration cooler and the second interface. When the first switch is closed, the refrigeration cooler can be directly connected to the refrigerator evaporator.

[0010] Furthermore, in the above technical solution, an evaporating fan is provided on the air-conditioning evaporator, and a condensing fan is provided on the refrigeration unit.

[0011] Furthermore, in the above technical solution, the refrigerator evaporator includes at least a refrigerated evaporator and a frozen evaporator, one end of the refrigerated evaporator and the frozen evaporator are connected to the three-way valve through a solenoid valve, and a second throttle valve and a third throttle valve are respectively arranged between the solenoid valve and the refrigerated evaporator and the frozen evaporator.

[0012] Furthermore, in the above technical solution, a drying filter is provided between the refrigeration device and the three-way valve.

[0013] In order to solve the above technical problems, the present invention adopts the following second technical solution: a refrigerator-air conditioner integrated machine with a shared compressor, comprising: a compressor, a refrigeration cooler, an air-conditioning evaporator, a refrigerator evaporator, a four-way reversing valve, and a three-way valve, wherein one end of the refrigeration cooler, the air-conditioning evaporator, and the refrigerator evaporator are arranged in parallel through the three-way valve, and the other end of the refrigeration cooler, the air-conditioning evaporator, and the refrigerator evaporator The four-way reversing valve is connected to the compressor; a first throttle valve is arranged between the air-conditioning evaporator and the three-way valve, and a second throttle valve is respectively arranged between the refrigerator evaporator and the three-way valve; when working, the first interface of the four-way reversing valve is connected to the second interface, and the third interface is connected to the fourth interface , the first switch is disconnected, the second switch is closed, the first throttle valve, the second throttle valve, and the third throttle valve are all opened. Of course, the first throttle valve, the second throttle valve, and the third throttle valve can be independently controlled to open and close; in this working mode, the gas pumped out from the compressor enters the condenser through the first interface and the second interface, and after the gas is refrigerated by the condenser, it is dried and filtered by the drying filter, and then diverted from the three-way valve to the air-conditioning evaporator and the solenoid valve, and finally enters the air-conditioning evaporator and the refrigerator evaporator to realize air-conditioning refrigeration and refrigerator refrigeration. Subsequently, the gas that exchanges heat returns to the compressor through the fourth interface and the third interface of the four-way reversing valve, thereby realizing the closed-loop circulation of the gas.

[0014] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the present invention adopts a compressor and a condenser in combination with a four-way reversing valve and a first switch and a second switch, and realizes independent cooling and heating or synchronous cooling, heating or other working modes of the air-conditioning evaporator and the refrigerator evaporator through the switching control of the four-way reversing valve and the first switch and the second switch, which not only makes the structure more compact and reduces the occupied space, but also has low energy consumption, saves energy and reduces emissions, and can adapt to a variety of occasions. For example: as a mobile air-conditioning refrigerator all-in-one machine, it can be used in outdoor activities such as camping. At this time, an outdoor mobile power supply or electric car can power the device, making it more portable. Description of the drawings:

[0020] See Figures 1 to 4 As shown, a refrigerator-air conditioner integrated machine with a shared compressor comprises: a compressor 1, a refrigeration cooler 2, an air-conditioning evaporator 4, a refrigerator evaporator 5, a four-way reversing valve 7, and a three-way valve 8, wherein one end of the refrigeration cooler 2, the air-conditioning evaporator 4, and the refrigerator evaporator 5 are arranged in parallel through the three-way valve 8, and the other end of the refrigeration cooler 2, the air-conditioning evaporator 4, and the refrigerator evaporator 5 The four-way reversing valve 7 is connected to the compressor 1; a first throttle valve 13 is arranged between the air-conditioning evaporator 4 and the three-way valve 8, and a second throttle valve 14 is respectively arranged between the refrigerator evaporator 5 and the three-way valve 8. A compressor 1 and a condenser 2 are used in combination with a four-way reversing valve 2, a first throttle valve 13 and a second throttle valve 14, so that one compressor 1 can simultaneously satisfy the air conditioning refrigeration function and the refrigerator refrigeration function. This not only makes the structure more compact and reduces the occupied space, but also has low energy consumption, saves energy and reduces emissions, and can adapt to a variety of occasions. For example, as a mobile air-conditioning refrigerator all-in-one machine, it can be used in outdoor activities such as camping. At this time, an outdoor mobile power supply or an electric car can power the device, making it more portable.

[0021] A second circuit 10 is provided between the refrigeration device 2 and the four-way reversing valve 7 to connect the refrigerator evaporator 5, and a first switch 11 is provided on the second circuit 10, and a second switch 12 is provided between the refrigerator evaporator 5 and the air conditioner evaporator 4 and the four-way reversing valve 7. By adding the second circuit 10 and the first switch 11 and the second switch 12, under the coordinated control of the four-way reversing valve 2 and the first switch 11 and the second switch 12, the air conditioner evaporator 4 and the refrigerator evaporator 5 can realize independent cooling and heating or synchronous cooling and heating working modes, which can not only make the structure more compact and reduce the occupied space, but also have low energy consumption, save energy and reduce emissions, and can be adapted to various occasions, for example: as a mobile air conditioner refrigerator integrated machine, it can be used in outdoor activities such as going out for camping, and at this time, an outdoor mobile power supply or an electric car can power the device, making it more portable.

[0022] The four-way reversing valve 7 includes a first interface and a third interface respectively connected to the inlet and outlet of the compressor 1, a second interface connected to the condenser 2, and a fourth interface connected to the air conditioner evaporator 4 and the refrigerator evaporator 5 at the same time, wherein the second switch 12 is located between the fourth interface and the air conditioner evaporator 4 and the refrigerator evaporator 5, so as to disconnect the refrigerator evaporator 5 from the fourth interface without blocking the connection between the fourth interface and the air conditioner evaporator 4. One end of the second circuit 10 is connected between the refrigerator evaporator 5 and the second switch 12, and the other end of the second circuit 10 is connected between the condenser 2 and the second interface. When the first switch 11 is closed, the condenser 2 can be directly connected to the refrigerator evaporator 5.

[0023] One end of the second loop 10 is connected between the refrigerator evaporator 5 and the second switch 12, and the other end of the second loop 10 is connected between the condenser 2 and the second interface. When the first switch 11 is closed, the condenser 2 can be directly connected to the refrigerator evaporator 5. The air conditioner evaporator 4 is provided with an evaporation fan 41, and the condenser 2 is provided with a condensation fan 21.

[0024] The refrigerator evaporator 5 at least includes a refrigerating evaporator 51 and a freezing evaporator 52, one end of which is connected to the three-way valve 8 through a solenoid valve 9, and a second throttle valve 14 and a third throttle valve 15 are respectively arranged between the solenoid valve 9 and the refrigerating evaporator 51 and the freezing evaporator 52. A drying filter 3 is arranged between the refrigerator 2 and the three-way valve 8.

[0025] See Figure 1As shown, it is the first embodiment of the present invention, and its working mode is: air conditioning refrigeration, refrigerator refrigeration. At this time, the first interface of the four-way reversing valve 7 is connected with the second interface, the third interface is connected with the fourth interface, the first switch 11 is disconnected, the second switch 12 is closed, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all opened. Of course, the first throttle valve 13, the second throttle valve 14 and the third throttle valve 15 can be independently controlled to open and close, thereby realizing single air conditioning refrigeration, single refrigerator refrigeration, and any two groups of combined use. In this working mode, the gas pumped out from the compressor 1 enters the condenser 2 through the first interface and the second interface, and after the gas is refrigerated by the condenser 2, it is dried and filtered by the drying filter 3, and then it is diverted from the three-way valve 8 to the air conditioning evaporator 4 and the solenoid valve 9, and finally enters the air conditioning evaporator 4 and the refrigerator evaporator 5, realizing air conditioning refrigeration and refrigerator refrigeration. Then, the gas that exchanges heat returns to the compressor 1 through the fourth interface and the third interface of the four-way reversing valve 7, thereby realizing the closed-loop circulation flow of the gas.

[0026] See Figure 2 As shown, it is the second embodiment of the present invention, and its working mode is: air conditioning heating, refrigerator heating. At this time, the first interface of the four-way reversing valve 7 is connected with the fourth interface, the third interface is connected with the second interface, the first switch 11 is disconnected, the second switch 12 is closed, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all opened. Of course, the first throttle valve 13, the second throttle valve 14 and the third throttle valve 15 can be independently controlled to open and close, thereby realizing single air conditioning heating, single refrigerator heating, and any two groups of combined use. In this working mode, the gas pumped out from the compressor 1 flows into the air conditioning evaporator 4 and the refrigerator evaporator 5 through the first interface and the fourth interface. Since the temperature of the gas is high at this time, the air conditioning heating and the refrigerator heating are realized. Subsequently, the gas that exchanges heat enters the condenser 2 through the solenoid valve 9 and the three-way valve 8 and the drying filter 3, and then returns to the compressor 1 from the condenser 2 through the second interface and the third interface of the four-way reversing valve 7, thereby realizing the closed-loop circulation of the gas.

[0027] See Figure 3As shown, it is the third embodiment of the present invention, and its working mode is: air conditioning cooling, refrigerator heating. At this time, the first interface of the four-way reversing valve 7 is connected with the second interface, the third interface is connected with the fourth interface, the first switch 11 is closed, the second switch 12 is disconnected, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all opened. Of course, the first throttle valve 13, the second throttle valve 14 and the third throttle valve 15 can be independently controlled to open and close, so as to realize the combined use of single air conditioning cooling and air conditioning cooling and refrigerator heating. In this working mode, the gas pumped out from the compressor 1 partially flows into the condenser 2 through the first interface and the fourth interface, and partially flows into the refrigerator evaporator 5 through the second circuit 10. Subsequently, the gas flowing into the condenser 2 is refrigerated and flows into the air-conditioning evaporator 4 through the three-way valve 8 after passing through the drying filter 3, while the gas flowing into the refrigerator evaporator 5 is combined with the solenoid valve 9 and also flows into the air-conditioning evaporator 4 through the three-way valve 8, thereby realizing the refrigeration of the air conditioner. Finally, the gas flowing into the air-conditioning evaporator 5 returns to the compressor 1 through the fourth interface and the third interface of the four-way reversing valve 7, thereby realizing the closed-loop circulation of the gas.

[0028] See Figure 4 As shown, it is the fourth embodiment of the present invention, and its working mode is: air conditioning heating, refrigerator cooling. At this time, the first interface of the four-way reversing valve 7 is connected with the fourth interface, the third interface is connected with the second interface, the first switch 11 is closed, the second switch 12 is disconnected, the first throttle valve 13, the second throttle valve 14, and the third throttle valve 15 are all opened. Of course, the first throttle valve 13, the second throttle valve 14 and the third throttle valve 15 can be independently controlled to open and close, so as to realize the single air conditioning heating, the air conditioning heating and refrigerator cooling combined use. In this working mode, the gas pumped out from the compressor 1 flows into the air conditioner evaporator 4 through the first interface and the fourth interface for heating. After heat exchange, the gas flows to the drying filter 3 and the solenoid valve 9 through the three-way valve 8 respectively. Subsequently, the gas passing through the drying filter 33 passes through the condenser 2 and returns to the compressor 1 through the second interface and the third interface of the four-way reversing valve 7, while the gas passing through the solenoid valve 8 flows to the refrigerator evaporator 5 for cooling, and then returns to the compressor 1 from the second circuit 10 through the second interface and the third interface of the four-way reversing valve 7, thereby realizing the closed-loop circulation of the gas.

[0029] In summary, in the present invention, through the coordinated control of the four-way reversing valve 7 and the first switch 11 and the second switch 12, a plurality of working modes of the air conditioner and the refrigerator can be realized by using a compressor 1 and a condenser 2, which greatly reduces the required energy consumption. It can not only reduce the power consumption of the household, but also facilitate the user's portable outdoor use, which greatly increases the scope of application of the equipment.
