The air conditioner of the present application performs a refrigerating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.
An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.
Fig. 1 shows a circuit configuration of an air conditioner 1, and the air conditioner 1 includes a refrigerant circuit 10, and is capable of performing a vapor compression refrigeration cycle by circulating a refrigerant in the refrigerant circuit 10. The indoor unit 3 and the outdoor unit 2 are connected to each other by a connection pipe 4 to form a refrigerant circuit 10 through which a refrigerant circulates. The refrigerant circuit 10 includes a compressor 11, an outdoor heat exchanger 13, an expansion valve 14, a receiver 15, and an indoor heat exchanger 16. The indoor heat exchanger 16 and the outdoor heat exchanger 13, among others, function as a condenser or an evaporator. The compressor 11 sucks in refrigerant from the suction port, and discharges the refrigerant compressed therein to the indoor heat exchanger 16 from the discharge port. The compressor 11 is an inverter compressor of variable capacity that performs rotational speed control based on an inverter, and the four-way valve 12 switches between heating and cooling.
The outdoor heat exchanger 13 has a first inlet and outlet for passing the refrigerant between the outdoor heat exchanger and the suction port of the compressor 11 via the accumulator 15, and has a second inlet and outlet for passing the refrigerant between the outdoor heat exchanger and the expansion valve 14. The outdoor heat exchanger 13 exchanges heat between the outdoor air and the refrigerant flowing through a heat transfer tube (not shown) connected between the second inlet and the first inlet of the outdoor heat exchanger 13.
The expansion valve 14 is disposed between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 has a function of expanding and decompressing the refrigerant flowing between the outdoor heat exchanger 13 and the indoor heat exchanger 16. The expansion valve 14 is configured to be capable of changing the opening degree, and the opening degree is reduced to increase the flow resistance of the refrigerant passing through the expansion valve 14, and the opening degree is increased to decrease the flow resistance of the refrigerant passing through the expansion valve 14. The expansion valve 14 expands and decompresses the refrigerant flowing from the indoor heat exchanger 16 to the outdoor heat exchanger 13 during the heating operation. Further, even if the state of other devices mounted in the refrigerant circuit 10 does not change, when the opening degree of the expansion valve 14 changes, the flow rate of the refrigerant flowing in the refrigerant circuit 10 changes.
The indoor heat exchanger 16 has a second inlet and outlet for allowing the liquid refrigerant to flow between the expansion valve 14 and a first inlet and outlet for allowing the gas refrigerant to flow between the gas refrigerant and the discharge port of the compressor 11. The indoor heat exchanger 16 exchanges heat between the indoor air and the refrigerant flowing through the heat transfer tube connected between the second inlet and the first inlet of the indoor heat exchanger 16.
A receiver 15 is disposed between the outdoor heat exchanger 13 and the suction port of the compressor 11. In the accumulator 15, the refrigerant flowing from the outdoor heat exchanger 13 to the compressor 11 is separated into a gas refrigerant and a liquid refrigerant. The gas refrigerant is mainly supplied from the accumulator 15 to the suction port of the compressor 11.
The outdoor unit 2 further includes an outdoor fan 21, and the outdoor fan 21 generates an airflow of the outdoor air passing through the outdoor heat exchanger 13 to promote heat exchange between the refrigerant flowing through the heat transfer tubes and the outdoor air. The outdoor fan 21 is driven by an outdoor fan motor 21A capable of changing the rotational speed. The indoor unit 3 further includes an indoor fan 31, and the indoor fan 31 generates an airflow of the indoor air passing through the indoor heat exchanger 16 to promote heat exchange between the indoor air and the refrigerant flowing through the heat transfer pipe. The indoor fan 31 is driven by an indoor fan motor 31A capable of changing the rotational speed.
Blood oxygen saturation (letter code SaO 2): blood oxygen saturation is the percentage of the volume of oxyhemoglobin bound by oxygen in the blood to the volume of total hemoglobin that can be bound, i.e., the concentration of blood oxygen in the blood, which is an important physiological parameter in the respiratory circulatory system. Whether the human body is healthy or not can be reflected from the blood oxygen saturation, and the symptoms such as shortness of breath, insufficient energy supply, fatigue and the like can appear for the person with low blood oxygen saturation.
Carbon dioxide concentration: when the carbon dioxide concentration is higher, the human body can show symptoms such as choking, dizziness and the like, and the high carbon dioxide concentration can lead to the reduction of the blood oxygen saturation.
As described in the background art, in the prior art, because the oxygen saturation of human blood is not considered, the air outlet of the air conditioner cannot be accurately controlled, and the user experience is affected.
According to the embodiment of the application, the controller is communicated with the wearable equipment which is worn by a user and can detect the blood oxygen saturation of the human body, the blood oxygen saturation of the user is obtained, the carbon dioxide concentration in the room is detected and obtained through the carbon dioxide concentration sensor, and after the air conditioner enters the first preset operation mode for a preset period of time, for example, the sleep operation mode, the air conditioner is controlled according to the blood oxygen saturation and the carbon dioxide concentration, so that the air outlet of the air conditioner is controlled more accurately, the air outlet control efficiency of the air conditioner is improved, and the user experience is improved.
The control logic of the controller is as follows:
the user starts (can use remote controller and software APP to start) to set up the sleep function, the controller is through software APP suggestion, inquires whether the user authorizes the controller to acquire the blood oxygen saturation data that wearable equipment gathered, and after the user agrees, the air conditioner gets into sleep control mode, and sleep control mode's initial state can be for indoor fan is running with lower wind speed, and fresh air fan is in the stopped state.
