At this time, the third throttling part 110 is controlled to reduce the opening degree, so that the temperature of the second heat exchanging part is reduced, and then the temperature of the mixed air flow passing through the first heat exchanging part and the second heat exchanging part is reduced, thereby ensuring the indoor temperature balance.

Specifically, the temperature of the second heat exchanging portion can be controlled to be lower, and the second heat exchanging portion is used for dehumidifying the mixed air flow, the first heat exchanging portion is used for adjusting the temperature of the dehumidified air flow, that is, the indoor side heat exchanger is specifically divided into the first flow path 102 and the second flow path 104, the fresh air introduced outdoors and the air-conditioning return air are mixed, and then the mixed air flow passes through the first heat exchanging portion, the temperature of the second heat exchanging portion is lower than the air dew point, and then the air flow passing through the second heat exchanging portion is dehumidified. The first heat exchanging part has a high temperature, and a specific heating amount can be set according to the indoor temperature, so that the temperature of part of the air flow passing through the second heat exchanging part is increased. The air current mixes once more after first heat transfer portion and second heat transfer portion, finally obtains the temperature and accords with and the air current through the dehumidification with indoor temperature, is sent to indoorly, and then under the prerequisite that need not add independent dehumidification module, has realized the function of new trend dehumidification, and the temperature value of new trend after can effectual adjustment dehumidification simultaneously avoids the dehumidification function to produce the influence to indoor temperature, has improved air conditioning equipment 100's use and has experienced.

The air conditioner 100 has a first air duct, a second air duct, and a third air duct. The first air channel is a fresh air channel and used for introducing outdoor fresh air. The second air duct is a return air duct, and indoor air is sucked into the second air duct by the indoor side of the air conditioning equipment 100 and blown out after the first heat exchanger contacts and exchanges heat, so that the indoor temperature is adjusted. The third air duct is communicated with the first air duct and the second air duct, outdoor air entering through the first air duct and indoor air entering through the second air duct are mixed in the third air duct, and become air with proper temperature and humidity after temperature control and dehumidification through the first flow path 102 and the second flow path 104, and the air is blown into a room through an air outlet formed by the third air duct.

The first detection piece is arranged at the air outlet and used for detecting first humidity, namely air outlet humidity. The second detects the piece and sets up in first wind channel for detect the second humidity, new trend humidity promptly. When the first humidity is higher than the second humidity, the outlet air humidity is higher than the outdoor fresh air humidity. At this time, the dehumidification force needs to be increased, specifically, the opening degree is reduced by controlling the third throttling element 110, so that the temperature of the first flow path 102 is reduced, the dehumidification effect is improved, and the indoor humidity is ensured to be proper.

Wherein, the temperature difference threshold value can be freely set according to the requirement of a user on a comfortable temperature range. The smaller the temperature difference threshold, the more precise the control and the more frequent the air conditioning unit 100 is acting. The larger the temperature difference threshold, the less the air conditioning apparatus 100 is operated, and the lower the power consumption.

The first instruction is a constant temperature dehumidification instruction, and in the constant temperature dehumidification mode, the third throttling element 110 is fully opened and the opening degrees of the second throttling element 108 and the first throttling element 106 are adjusted along with the outlet air temperature and the return air temperature.

and step 806, controlling the first throttling element and the second throttling element to be fully opened based on a third instruction, determining a second opening according to the third instruction, and controlling the third throttling element to open the second opening.

The first instruction is a constant-temperature dehumidification instruction, the second instruction is a refrigeration instruction, and the third instruction is a heating instruction.

In this embodiment, when the fresh air mode is turned on, the fresh air introduced from the outside and the indoor return air are mixed in the cavity of the air conditioning apparatus to form a mixed air flow. When a first instruction is received, the air conditioning equipment is controlled to operate in a fresh air constant temperature dehumidification mode, and at the moment, the fresh air dehumidification function is guaranteed, and meanwhile, the indoor constant temperature is kept. In order to maintain constant temperature dehumidification, the temperature of the first heat exchanging part and the second heat exchanging part is adjusted, so that the first flow path and the second flow path respectively dehumidify and adjust the temperature of the mixed gas flow.

In the constant temperature dehumidification mode, the temperature of the refrigerant in the first flow path is lower, and the refrigerant is used for dehumidification; the temperature of the refrigerant in the second flow path is higher, and the refrigerant is used for reheating the airflow after the refrigerant is contacted with the first flow path so as to ensure that the outlet air temperature of the air conditioning equipment conforms to the return air temperature.

When the first humidity is higher than the second humidity, the outlet air humidity is higher than the outdoor fresh air humidity. At this moment, the dehumidification force is required to be increased, and the opening degree is specifically reduced by controlling the third throttling element, so that the temperature of the first flow path is reduced, the dehumidification effect is improved, and the indoor humidity is ensured to be proper.

And receiving a setting instruction, and determining a temperature difference threshold value and a minimum opening threshold value and a maximum opening threshold value corresponding to the second throttling element according to the setting instruction so as to realize specific control on the work of the air conditioning equipment. Wherein, the temperature difference threshold value can be freely set according to the requirement of a user on a comfortable temperature range. The smaller the temperature difference threshold, the more accurate the control and the more frequent the air conditioning equipment acts. The larger the temperature difference threshold value is, the less the air conditioning equipment acts, and the energy consumption is reduced accordingly.

The first instruction is a constant-temperature dehumidification instruction, and in a constant-temperature dehumidification mode, the third throttling element is fully opened and the opening degrees of the second throttling element and the first throttling element are adjusted along with the air outlet temperature and the air return temperature. The second instruction is a refrigeration instruction, the third throttling element is fully opened in the refrigeration mode, the target refrigeration temperature corresponding to the instruction mode is determined, and the first throttling element and the second throttling element are specifically controlled to be opened at the first opening degree according to the target refrigeration temperature. And the third instruction is a heating instruction, under the heating mode, the corresponding target heating temperature is determined according to the heating mode, the third throttling element is specifically controlled to open the second opening according to the target heating temperature, and the first throttling element and the second throttling element are controlled to be fully opened.

In the cooling mode and the heating mode, the first flow path and the second flow path have the same function and are both used for cooling or heating, and at this time, the serial structure or the parallel structure of the first flow path and the second flow path can be regarded as a complete whole.

EXAMPLE III

In one embodiment of the present invention, the exhaust end of the compressor is connected to a four-way valve, the four-way valve is connected to an outdoor evaporator, an outlet of the outdoor evaporator is connected to a third throttling element, an outlet of the third throttling element is connected to a refrigerant heat dissipation device, and a refrigerant heat dissipation pipeline passing through the refrigerant heat dissipation device is divided into two paths: one of the pipelines is connected with the first throttling element to form a first flow path, and the other pipeline is connected with the second throttling element to form a second flow path. The first flow path and the second flow path are connected to the first heat exchanging portion and the second heat exchanging portion, respectively.

Specifically, the indoor side evaporator is divided into two parts, namely a first heat exchanging part and a second heat exchanging part, wherein the first heat exchanging part and the second heat exchanging part are arranged in parallel from top to bottom, a first flow path is connected with the first heat exchanging part, and a second flow path is connected with the second heat exchanging part.

The pipeline at the outlet of the first heat exchanging part is divided into two paths: one path of the first heat exchanging part and the outlet pipeline of the second heat exchanging part are combined into one path of the second heat exchanging part and return to the four-way valve, and finally return to the air return end of the compressor to form a closed loop; the other path is connected with an inlet end pipeline of the refrigerant heat dissipation device.

When the refrigerant passes through the first throttling element which is not throttled after coming out of the outdoor heat exchanger and flows through the refrigerant heat dissipation device, the state of the refrigerant at this moment is a liquid refrigerant with higher temperature (the refrigerant before throttling), and at this moment: one path of refrigerant flows into the second heat exchange part through the second throttling part, the opening degree of the second throttling part is adjusted according to specific conditions, so that the second heat exchange part is a liquid refrigerant with higher temperature, and the second heat exchange part can be regarded as a heater. The other path of refrigerant flows into the first heat exchange part through the first throttling part, the opening degree of the first throttling part is adjusted according to specific conditions, so that the refrigerant is evaporated and absorbs heat in the first heat exchange part, the air flowing through the first heat exchange part is cooled, and when the surface temperature of the fins of the first heat exchange part is lower than the dew point temperature of the air flowing through the first heat exchange part, the effects of cooling and dehumidifying the air flowing through the first heat exchange part can be achieved.

Specifically, the air conditioning apparatus includes at least three operating modes:

and in the refrigeration mode, the opening degree of the third throttling element is the maximum value, and the opening degrees of the first throttling element and the second throttling element are the same set value.

And in the constant-temperature dehumidification mode, the opening degree of the third throttling element is the maximum value, and the opening degrees of the first throttling element and the second throttling element are different set values.

And in the heating mode, the opening degree of the third throttling element is a set value, and the opening degrees of the first throttling element and the second throttling element are maximum values.

The cooling and heating modes are normal air conditioner operation modes, and at the moment, the first flow path and the second flow path achieve the same purpose, which is equivalent to forming an indoor side heat exchanger with two inlets and two outlets.

Under the constant temperature dehumidification mode, the new trend motor is opened, the new trend blows to indoor from outdoor earlier, indoor motor begins the operation and inhales indoor air to interior wind channel, the air in the wind channel is the mixed air of indoor original air and outdoor new trend this moment, partly through the first flow path cooling dehumidification in the mixed air, another part is through the heating of second flow path, two parts mix the heat transfer in the third wind channel, the lower dehumidification wind of process that final temperature is lower, the higher indoor return air that does not pass through the dehumidification of temperature mixes, reach the median of temperature, form the air current that the humiture is suitable, finally blown again indoor, reach the effect of constant temperature dehumidification.

Wherein the fresh air continuously enters the room and is used as indoor air to participate in the constant temperature dehumidification cycle again.

Specifically, temperature sensors are provided at an air outlet and a return air inlet of the indoor-side air conditioner.

The temperature sensor of the return air inlet detects that the indoor return air temperature is T1, the temperature sensor of the air outlet detects that the outlet air temperature is T2, and T1 and T2 are compared.

When T1> T2 and T1-T2> M, the opening degree of the first throttle is increased, and the rotation speed of the fan is reduced. At this moment, the temperature of the inlet air is higher than that of the air at the air outlet and is higher than a comfortable range (determined by a threshold value M), and the heating temperature of the indoor side heat exchanger needs to be increased, so that the air outlet temperature of the air outlet is increased. The aim is to maintain dehumidification at a certain temperature. The reason for reducing the motor speed is to avoid the air with lower temperature at the air outlet from directly blowing the air indoors.

When T1> T2 and T1-T2< M, the temperature of the inlet air is higher than that of the outlet air and is not higher than a comfortable range, and the state operation is maintained, so that frequent actions are avoided, and unnecessary waste is avoided.

When T1< T2 and T2-T1> M, the opening degree of the third throttle is decreased. The temperature of the air outlet air is higher than that of the air in the air inlet and higher than a comfortable range, and the temperature of the indoor side heat exchanger needs to be reduced, so that the air outlet temperature of the air outlet is reduced. The aim is to maintain dehumidification at a certain temperature. The reason why the rotation speed of the motor is not reduced at this time is because there is no air with a low temperature blowing the indoor air.

When T1< T2 and T2-T1< M, the temperature of the outlet air is higher than that of the inlet air and is not higher than a comfortable range, and the state operation is maintained, so that frequent actions are avoided, and unnecessary waste is avoided.

The complete control logic is shown in fig. 9:

step S902, starting a fresh air dehumidification mode;

step S904, detecting the return air temperature T1 and the outlet air temperature T2;

step S906, comparing the sizes of T1 and T2; if T1< T2, go to step S908; if T1> T2, go to step S912;

step S908, judging whether T2-T1< M is satisfied; if yes, go to step S916, otherwise go to step S910;

step S910, reducing the opening degree of the third throttling element;

step S912, judging whether T1-T2< M is met; if yes, go to step S916, otherwise go to step S914;

step S914, increasing the opening of the first throttling element and simultaneously reducing the rotating speed of the fan;

step S916, maintaining the current operation state;

in step S918, the fresh air dehumidification mode is closed.

Example four

Specifically, temperature sensors are arranged at an air outlet and an air return inlet of the indoor air conditioner, and humidity sensors are arranged at a fresh air duct and the air outlet.

The temperature sensor at the return air inlet detects that indoor return air temperature is T1, and the temperature sensor at the air outlet detects that the air-out temperature is T2, air outlet humidity H1, and new trend wind channel humidity is H2.

When T1> T2 and T1-T2> M, the opening degree of the first throttle is increased, and the rotation speed of the fan is reduced. At this moment, the temperature of the inlet air is higher than that of the air at the air outlet and is higher than a comfortable range (determined by a threshold value M), and the heating temperature of the indoor side heat exchanger needs to be increased, so that the air outlet temperature of the air outlet is increased. The aim is to maintain dehumidification at a certain temperature. The reason for reducing the motor speed is to avoid the air with lower temperature at the air outlet from directly blowing the air indoors. At this time, when H1 and H2 are compared, if H1> H2, the opening degree of the third throttle is decreased, and the dehumidification effect is improved. If H1< H2, the dehumidification effect is obvious.

When T1< T2 and T2-T1> M, the opening degree of the third throttle is decreased. The temperature of the air outlet air is higher than that of the air in the air inlet and higher than a comfortable range, and the temperature of the indoor side heat exchanger needs to be reduced, so that the air outlet temperature of the air outlet is reduced. The aim is to maintain dehumidification at a certain temperature. The reason why the rotation speed of the motor is not reduced at this time is because there is no air with a low temperature blowing the indoor air. If H1> H2, the opening degree of the third throttling element is continuously reduced, and the dehumidification effect is improved. If H1< H2, the dehumidification effect is obvious.
