As shown in fig. 1 to 4, an embodiment of the present disclosure provides an air conditioning system including an indoor unit 31, an outdoor unit, a compressor 32, a first circulation assembly, and a second circulation assembly. The compressor 32 is disposed in the outdoor unit body; the first circulation module comprises a first indoor heat exchanger 11, a first outdoor heat exchanger 12 and a first throttling device 13; the first circulation assembly is connected with the compressor 32 to form a first refrigerant circulation loop, wherein the first indoor heat exchanger 11 is communicated with a return air port of the compressor 32, and the first outdoor heat exchanger 12 is communicated with an exhaust port of the compressor 32; the second circulation module includes a second indoor heat exchanger 21, a second outdoor heat exchanger 22, a second throttle device 23, and a four-way valve 24; the second circulation component is connected with the compressor 32 to form a second refrigerant circulation loop; wherein, the first indoor heat exchanger 11 and the second indoor heat exchanger 21 are commonly disposed in the indoor body 31.
By adopting the air conditioning system provided by the embodiment of the disclosure, when the first refrigerant circulation loop is in a passage state, the air conditioner can realize a basic refrigeration function; when the first refrigerant circulation loop and the second refrigerant circulation loop are both in a passage state, the air conditioner can realize a constant-temperature dehumidification function. And the refrigerant circulation in the air conditioner is simple and reasonable in flow distribution, and the manufacturing cost is low.
In some embodiments, as shown in fig. 1 and 2 (the direction of the arrow in the figure indicates the flow direction of the refrigerant), in the first refrigerant circulation loop, the high-temperature and high-pressure gaseous refrigerant enters the first outdoor heat exchanger 12 from the air outlet of the compressor 32, exchanges heat with outdoor air and releases heat, then flows into the first indoor heat exchanger 11, exchanges heat with air blown through the first indoor heat exchanger 11 and absorbs heat of the air, and finally flows into the compressor 32 through the air return opening of the compressor 32. In this way, the first refrigerant circulation circuit can perform a cooling function.
In the second refrigerant circulation circuit, when the valve port a and the valve port B, and the valve port C and the valve port D of the four-way valve 24 are connected, a high-temperature and high-pressure gaseous refrigerant flows out from the exhaust port of the compressor 32, sequentially passes through the valve port C and the valve port D of the four-way valve 24, enters the second outdoor heat exchanger 22, exchanges heat with outdoor air in the second outdoor heat exchanger 22, releases heat, flows into the second indoor heat exchanger 21, exchanges heat with air blown through the second indoor heat exchanger 21, absorbs heat of the air, and finally flows into the compressor 32 from the return air port of the compressor 32 sequentially passes through the valve port B and the valve port a of the four-way valve 24. When the valve port a and the valve port D, and the valve port B and the valve port C of the four-way valve 24 are turned on, a high-temperature and high-pressure gaseous refrigerant enters the second indoor heat exchanger 21 from the exhaust port of the compressor 32, exchanges heat with air flowing through the second indoor heat exchanger 21 and releases heat to heat the air, then enters the second outdoor heat exchanger 22 and exchanges heat with outdoor air to absorb heat, and finally flows into the compressor 32 from the return air port of the compressor 32 through the valve port D and the valve port a of the four-way valve 24 in sequence.
In some embodiments, the first throttling means 13 comprises a capillary tube and a switching valve, or, alternatively, an electronic expansion valve; and/or the second throttling means 23 comprise a capillary tube and a switching valve, or alternatively, an electronic expansion valve. The throttling device is mainly used for adjusting the refrigerant flow of the first refrigerant circulation loop and the second refrigerant circulation loop and the pressure of the air conditioning system.
Optionally, the first throttling device 13 and the second throttling device 23 may further include a throttle valve and a thermal expansion valve.
Optionally, an electronic expansion valve, a switch valve and a capillary tube are sequentially connected between the first indoor heat exchanger 11 and the first outdoor heat exchanger 12, and between the second indoor heat exchanger 21 and the second outdoor heat exchanger 22.
In the above embodiment, further, the electronic expansion valve may be electromagnetic or electric.
In some embodiments, the air conditioning system further comprises a dehumidification controller. The dehumidification controller is used for sending an opening instruction to the second throttling device 23 and controlling the conduction of different valve ports of the four-way valve 24 to enable the air conditioner to enter a first mode or a second mode, or sending a closing instruction to the second throttling device 23 to enable the air conditioner to enter a third mode. Therefore, the throttling device is opened after receiving an opening instruction from the dehumidification controller, so that the second refrigerant circulation loop is changed into a passage state; the throttling device is closed after receiving a closing instruction from the dehumidification controller, so that the second refrigerant circulation loop becomes a cut-off state.
In the above embodiment, optionally, the dehumidification controller can receive a first sensing signal of the air conditioner remote controller, and send an opening instruction to the second throttling device 23 after receiving the first sensing signal, and control the four-way valve 24 to be turned on corresponding to the valve port. Therefore, the air conditioner can be conveniently enabled to enter the first mode through the air conditioner remote controller.
In the above embodiment, optionally, the dehumidification controller can receive a second sensing signal of the air conditioner remote controller, and send an opening instruction to the second throttling device 23 after receiving the second sensing signal, and control the four-way valve 24 to be turned on corresponding to the valve port. Therefore, the air conditioner can be conveniently enabled to enter the second mode through the air conditioner remote controller.
In the above embodiment, optionally, the dehumidification controller may receive a third sensing signal of the air conditioner remote controller, and send a closing instruction to the second throttling device 23 after receiving the third sensing signal, so that the second refrigerant circulation loop is cut off. Therefore, the air conditioner can be conveniently enabled to enter the third mode through the air conditioner remote controller.
In some embodiments, the first mode is a constant temperature dehumidification mode, the second mode is an enhanced cooling mode, and the third mode is a normal cooling mode.
In the third mode, the first refrigerant circulation circuit is in a passage state, the second refrigerant circulation circuit is in a cut-off state, and the air conditioner in the third mode reduces the indoor temperature through the first indoor heat exchanger 11, wherein the first mode is called a normal cooling mode; in a second mode, the first refrigerant circulation loop is in a passage state, and meanwhile, a valve port A and a valve port B, and a valve port C and a valve port D of the four-way valve 24 in the second refrigerant circulation loop are communicated, in the second mode, the air conditioner simultaneously reduces the indoor temperature through the first indoor heat exchanger 11 and the second indoor heat exchanger 21, and at the moment, the second mode is called as an enhanced refrigeration mode; in the first mode, the first refrigerant circulation loop is in a passage state, meanwhile, the valve port A and the valve port D, the valve port B and the valve port C of the four-way valve 24 in the second refrigerant circulation loop are communicated, in the first mode, the refrigerant absorbs heat of passing air in the first indoor heat exchanger 11 to reduce air temperature, water vapor in the indoor air is solid when meeting condensation and is dehumidified, the refrigerant in the second indoor heat exchanger 21 releases heat to heat the dehumidified low-temperature air, and finally, the dehumidified and heated air is blown into a room in sequence, and the third mode is called as a constant-temperature dehumidification mode.
In some embodiments, as shown in fig. 3, the first indoor heat exchanger 11 and the second indoor heat exchanger 21 are arranged at intervals along the air passage direction of the indoor unit body 31. Thus, the air in the air duct first passes through the first indoor heat exchanger 11, then passes through the second indoor heat exchanger 21, and finally is blown into the room by the cross flow fan.
In the above embodiment, optionally, when the state of the air conditioner is in the normal cooling mode, the air in the air duct firstly passes through the first indoor heat exchanger 11, and the refrigerant in the first indoor heat exchanger 11 exchanges heat with the air and absorbs heat; since the second refrigerant circulation circuit is in the blocked state and no refrigerant flows through the second indoor heat exchanger 21, the temperature of the air blown through the second indoor heat exchanger 21 is not changed, and finally only the air heat-exchanged with the first indoor heat exchanger 11 is blown into the room by the internal fan 33.
In the above embodiment, optionally, when the state of the air conditioner is in the enhanced cooling mode, when the air in the air duct first passes through the first indoor heat exchanger 11, the refrigerant in the first indoor heat exchanger 11 exchanges heat with the air and absorbs heat; because the valve port a and the valve port B, the valve port C and the valve port D of the four-way valve 24 in the second refrigerant circulation loop are connected, if the temperature of part of the air after heat exchange with the first indoor heat exchanger 11 does not reach the target temperature preset by the user, the part of the air is blown to the second indoor heat exchanger 21 and performs secondary heat and cold exchange with the second indoor heat exchanger, so that the temperature of the air blown to the indoor space can be further ensured to reach the target temperature.
In the above embodiment, optionally, when the air conditioning state is in the constant temperature dehumidification mode, the first indoor heat exchanger 11 absorbs heat of indoor air, and water vapor in the indoor air is condensed and dehumidified; because the valve port A and the valve port D, and the valve port B and the valve port C of the four-way valve 24 in the second refrigerant circulation loop are communicated, the refrigerant in the second indoor heat exchanger 21 can release heat, the dehumidified low-temperature air is blown to the second indoor heat exchanger 21 and heated, and finally the air which is successively cooled, dehumidified and heated is blown into the room. Therefore, the indoor temperature is not changed, and the aim of dehumidifying air can be fulfilled.
Further, the entire volume of the first indoor heat exchanger 11 is greater than or equal to the entire volume of the second indoor heat exchanger 21. Because the first indoor heat exchanger 11 and the second indoor heat exchanger 21 are sequentially arranged at intervals along the air duct direction of the indoor unit body 31, the air in the air duct inevitably passes through the first indoor heat exchanger 11 and then passes through the second indoor heat exchanger 21; and because the whole volume of the first indoor heat exchanger 11 is greater than or equal to the whole volume of the second indoor heat exchanger 21, the dehumidification effect can be improved, and the condition that part of the air in the air duct is blown to the second indoor heat exchanger 21 without being dehumidified is avoided.
In some embodiments, as shown in fig. 4, the first indoor heat exchanger 11 and the second indoor heat exchanger 21 are arranged side by side in the axial direction of the inner fan 33 of the indoor unit body 31.
In the above embodiment, optionally, when the air conditioning state is in the constant temperature dehumidification mode, since the first indoor heat exchanger 11 and the second indoor heat exchanger 21 are arranged side by side along the axial direction of the inner fan 33 of the indoor unit 31, the air in the air duct passes through the first indoor heat exchanger 11 and the second indoor heat exchanger 21 at the same time, the air passing through the first indoor heat exchanger 11 is subjected to condensation and dehumidification and temperature reduction, the air passing through the second indoor heat exchanger 21 is heated but humidity is not changed, and thus, the dehumidified and cooled air and the heated air are mixed and blown into the room.
In the above embodiment, optionally, the inner fan 33 includes a first fan and a second fan. The first inner fan is arranged corresponding to the first indoor heat exchanger 11, and the second inner fan is arranged corresponding to the second indoor heat exchanger 21. Thus, under the action of the first inner fan, the air in the air duct is quickly cooled and dehumidified by the first indoor heat exchanger 11; under the effect of the second inner fan, air in the air duct is heated quickly through the second indoor heat exchanger 21, and finally the dehumidified and cooled air and the heated air are mixed and blown into the room.
Further, the inner fan 33 further includes a motor controller electrically connected to the indoor humidity sensor and the indoor temperature sensor of the air conditioner, and capable of controlling the rotation states of the first inner fan and the second inner fan according to the feedback signals of the indoor humidity sensor and the indoor temperature sensor.
Illustratively, the constant temperature dehumidification function of the air conditioner is turned on under the condition that the indoor temperature is 20 ℃ and the indoor humidity is 60%, and the target humidity preset by the user is 40%. If after the air conditioner works for 15 minutes with the constant-temperature dehumidification function, the indoor humidity sensor detects that the indoor humidity is not reduced to the target humidity, the indoor humidity sensor sends a feedback signal to the motor controller, the motor controller controls the first inner fan to increase the rotating speed after receiving the feedback signal, so that the air in the air channel quickly passes through the first indoor heat exchanger 11, the air quickly passes through the first indoor heat exchanger 11 under the action of the first indoor heat exchanger 11 and is efficiently cooled and dehumidified, and the dehumidification efficiency is improved. If the indoor humidity sensor detects that the indoor humidity is reduced to the target humidity after the air conditioner works for 15 minutes with the constant-temperature dehumidification function, the indoor humidity sensor sends a feedback signal to the motor controller, and the motor control sensor controls the first inner fan to stop rotating after receiving the feedback signal. In the process that the air conditioner executes the constant temperature dehumidification function, if the indoor temperature sensor detects that the indoor temperature is lower than 20 ℃, the indoor temperature sensor sends a feedback signal to the motor controller, the motor controller controls the second inner fan to increase the rotating speed after receiving the feedback signal, so that the air in the air channel quickly passes through the second indoor heat exchanger 21 and is heated, more heated air enters the room, and the indoor temperature is increased.
In some embodiments, the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 are commonly disposed in the outdoor unit body, and the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 are sequentially arranged at intervals along the discharge air direction of the air duct of the outdoor unit body.
In the above embodiment, optionally, when the air conditioning state is in the constant temperature dehumidification mode, because the first refrigerant circulation loop is in the passage state, the refrigerant in the first outdoor heat exchanger 12 releases heat to the air; because the valve port A and the valve port D, and the valve port B and the valve port C of the four-way valve 24 in the second refrigerant circulation loop are communicated, the refrigerant in the second outdoor heat exchanger 22 absorbs the heat of the air passing through the refrigerant circulation loop; and because the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 are arranged at intervals in sequence along the air duct direction of the outdoor unit body, the air in the air duct inevitably passes through the first outdoor heat exchanger 12 and is heated, then passes through the second outdoor heat exchanger 22 and is cooled, and the air in the air duct is finally discharged out of the air duct after passing through the heating and cooling in sequence, so that the temperature of the air discharged to the outside of the air conditioner can be reduced.
Further, the entire volume of the second outdoor heat exchanger 22 is greater than or equal to the entire volume of the first outdoor heat exchanger 12. Thus, the air heated by the first outdoor heat exchanger 12 is ensured to be efficiently cooled by the second outdoor heat exchanger 22, and the cooling effect of the air in the exhaust air duct is improved.
In some embodiments, the first and second outdoor heat exchangers 12 and 22 are commonly disposed in the outdoor unit body, and the first and second outdoor heat exchangers 12 and 22 are disposed vertically up and down or laterally left and right side by side.
In the above embodiment, optionally, when the air conditioning state is in the constant temperature dehumidification mode, because the first refrigerant circulation loop is in the passage state, the refrigerant in the first outdoor heat exchanger 12 releases heat to the air; because the valve port A and the valve port D, and the valve port B and the valve port C of the four-way valve 24 in the second refrigerant circulation loop are communicated, the refrigerant in the second outdoor heat exchanger 22 absorbs the heat of the air passing through the refrigerant circulation loop; and because the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 are arranged side by side vertically or horizontally, the air heated by the first outdoor heat exchanger 12 and the air cooled by the second outdoor heat exchanger 22 are mixed and then discharged from the air duct.
Further, the outer fan of the outdoor unit body is an axial fan, and an axial projection of a boundary between the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 coincides with a radial line of the outer fan. Therefore, the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 which are arranged vertically and vertically or transversely and leftwards and rightwards in parallel can enable air in the air duct to rapidly pass through the first outdoor heat exchanger and the second outdoor heat exchanger under the blowing action of the outer fan.
Optionally, for the first outdoor heat exchanger 12 and the second outdoor heat exchanger 22 which are arranged in the outdoor unit body side by side up and down vertically or left and right horizontally, the external fan may include a first external fan and a second external fan, wherein the first external fan is arranged corresponding to the first outdoor heat exchanger 12, and the second external fan is arranged corresponding to the second outdoor heat exchanger 22.
