Examples
Referring to fig. 1 and fig. 2 in combination, an embodiment of the present invention provides an air conditioner 1 for regulating and controlling air temperature in a room. The refrigerant leakage amount can be reduced through self control adjustment when the refrigerant leaks, so that the use risk of the refrigerant is reduced, the safety performance is improved, and the practicability is high.
The air conditioner 1 includes a controller 2, an indoor unit 3, an outdoor unit 4, a first valve element 5, a second valve element 6, and a detector 7. One end of the indoor unit 3 is connected with the outdoor unit 4 through a first valve element 5, the other end of the indoor unit 3 is connected with the outdoor unit 4 through a second valve element 6, and the indoor unit 3, the first valve element 5, the outdoor unit 4 and the second valve element 6 are sequentially connected end to end and combined with the compressor 9 to form a refrigerant flow path 8. The detector 7 is attached to the refrigerant passage 8 and connected to the controller 2. The detector 7 can detect whether the refrigerant leaks in real time in the operation process of the air conditioner 1, and can judge the position of the refrigerant leakage, so as to send a control signal to the controller 2. The controller 2 is respectively connected with the indoor unit 3, the outdoor unit 4, the first valve element 5 and the second valve element 6, and the controller 2 can control each component to perform adjustment action when a refrigerant leaks so as to reduce the leakage amount of the refrigerant.
The outdoor unit 4 includes a compressor 9, a four-way reversing valve 10, a condenser 11, and a first fan 12. Both ends of the compressor 9 are connected with the four-way reversing valve 10, so that the heating or refrigerating function is realized under the action of the four-way reversing valve 10. The four-way reversing valve 10, the first valve member 5, the indoor unit 3, the second valve member 6 and the condenser 11 are connected end to end, and are combined with the compressor 9 to form a refrigerant flow path 8. The controller 2 is connected to the compressor 9, the four-way reversing valve 10, and the first fan 12, respectively, to control the operating frequency of the compressor 9, the operating state of the four-way reversing valve 10, and the rotational speed of the first fan 12. The first fan 12 is arranged at an interval from the condenser 11, and the first fan 12 is used for cooling the condenser 11 by air. When the outdoor unit 4 leaks, the controller 2 controls the first fan 12 to operate at the highest rotation speed, and the first fan 12 can blow away the leaked refrigerant in the outdoor unit 4 into the air, so that the concentration of the refrigerant in the environment is reduced, adverse effects caused by refrigerant leakage are reduced, and the safety of the air conditioner 1 in the use process is improved.
The indoor unit 3 includes an evaporator 13 and a second fan 14. One end of the evaporator 13 is connected with the first valve element 5, the other end is connected with the second valve element 6, and the four-way reversing valve 10, the first valve element 5, the evaporator 13, the second valve element 6 and the condenser 11 are connected end to end and combined with the compressor 9 to form the refrigerant flow path 8. The second fan 14 is connected to the controller 2 and is spaced apart from the evaporator 13, and the second fan 14 is used for blowing out air heated or cooled by the evaporator 13 to adjust the indoor air temperature. When the indoor unit 3 leaks, the controller 2 controls the second fan 14 to operate at the highest rotation speed, and the second fan 14 can blow away the leaked refrigerant in the outdoor unit 4 into the air, so that the concentration of the refrigerant in the environment is reduced, the adverse effect caused by the refrigerant leakage is reduced, and the safety of the air conditioner 1 in the use process is improved.
Referring to fig. 3, it is noted that, when a refrigerant leaks, the refrigerant flow path 8 has four leakage states, namely, leakage of the indoor unit 3 during a cooling process, leakage of the outdoor unit 4 during a cooling process, leakage of the indoor unit 3 during a heating process, and leakage of the outdoor unit 4 during a heating process, and the detector 7 sends different control signals to the controller 2 according to different leakage states, so that the controller 2 controls each component to perform different adjustment actions, thereby achieving a function of reducing refrigerant leakage under various leakage states.
It should be noted that the first valve element 5 can be opened or closed to open or block the refrigerant flow path 8, and a period of time is required from the start of the closing operation of the first valve element 5 to the complete closing operation. The second valve element 6 can be opened or closed to open or block the refrigerant passage 8, and a period of time is required from the start of the closing operation of the second valve element 6 to the complete closing operation.
When the indoor unit 3 leaks during the cooling process, the refrigerant flows in the refrigerant flow path 8 in the first direction (the direction from the outdoor unit 4 to the indoor unit 3 through the second valve element 6). The controller 2 controls the second valve element 6 to close to block the refrigerant flow path 8 at the inlet of the indoor unit 3 to prevent the refrigerant from entering the leakage point. During the closing process of the second valve element 6, the controller 2 controls the operating frequency of the compressor 9 to increase to the maximum frequency so as to reduce the pressure of the refrigerant in the indoor unit 3 and avoid pressing out excessive refrigerant from the refrigerant flow path 8, and during the process, the refrigerant in the indoor unit 3 continues to flow back to the compressor 9 under the action of the compressor 9. After the second valve element 6 is completely closed and the refrigerant is recovered, the controller 2 controls the first valve element 5 to be closed, and the air conditioner 1 is shut down to complete control and regulation.
When the outdoor unit 4 leaks in a refrigeration process, the refrigerant flows in the refrigerant flow path 8 in the first direction, and the controller 2 controls the four-way reversing valve 10 to reverse the direction, so that the air conditioner 1 heats, and the refrigerant flows in the refrigerant flow path 8 in the second direction (the direction from the outdoor unit 4 to the indoor unit 3 through the first valve element 5). The controller 2 controls the first valve 5 to close to block the refrigerant flow path 8 at the inlet of the outdoor unit 4, thereby preventing the refrigerant from entering the leakage point. The controller 2 controls the operation frequency of the compressor 9 to decrease during the closing of the first valve 5, so as to reduce the pressure of the refrigerant in the outdoor unit 4 and prevent the excessive refrigerant from being pressed out of the refrigerant flow path 8, and during this process, the refrigerant in the outdoor unit 4 continues to flow back to the compressor 9 under the action of the compressor 9. After the first valve 5 is completely closed, the controller 2 controls the compressor 9 to operate at the highest frequency, so as to accelerate the recovery speed of the refrigerant. After the refrigerant recovery is finished, the controller 2 controls the second valve element 6 to be closed, and the air conditioner 1 is shut down to finish control and regulation.
When the indoor unit 3 leaks in the heating process, the refrigerant flows in the refrigerant flow path 8 along the second direction, and the controller 2 controls the four-way reversing valve 10 to reverse the direction, so that the air conditioner 1 refrigerates, and the refrigerant flows in the refrigerant flow path 8 along the first direction. The controller 2 controls the second valve element 6 to close to block the refrigerant flow path 8 at the inlet of the indoor unit 3 to prevent the refrigerant from entering the leakage point. The controller 2 controls the operation frequency of the compressor 9 to increase to the maximum frequency during the closing of the second valve 6 to reduce the pressure of the refrigerant in the indoor unit 3 and prevent the excessive refrigerant from being pressed out of the refrigerant flow path 8, and during this process, the refrigerant in the indoor unit 3 continues to flow back to the compressor 9 under the action of the compressor 9. After the second valve element 6 is completely closed and the refrigerant is recovered, the controller 2 controls the first valve element 5 to be closed, and the air conditioner 1 is shut down to complete control and regulation.
When the outdoor unit 4 leaks during heating, the refrigerant flows in the refrigerant flow path 8 in the second direction. The controller 2 controls the first valve 5 to close to block the refrigerant flow path 8 at the inlet of the outdoor unit 4, thereby preventing the refrigerant from entering the leakage point. The controller 2 controls the operation frequency of the compressor 9 to decrease during the closing of the first valve 5, so as to reduce the pressure of the refrigerant in the outdoor unit 4 and prevent the excessive refrigerant from being pressed out of the refrigerant flow path 8, and during this process, the refrigerant in the outdoor unit 4 continues to flow back to the compressor 9 under the action of the compressor 9. After the first valve 5 is completely closed, the controller 2 controls the compressor 9 to operate at the highest frequency, so as to accelerate the recovery speed of the refrigerant. After the refrigerant recovery is finished, the controller 2 controls the second valve element 6 to be closed, and the air conditioner 1 is shut down to finish control and regulation.
