As shown in Figures 1-2, the air conditioner in the embodiment of the present disclosure includes an air conditioner outdoor unit 1 and an air conditioner indoor unit 2, wherein the air conditioner outdoor unit 1 includes a condensed water storage area, and the condensed water storage area is provided with a vent for fresh air 11. The indoor unit of the air conditioner is provided with a drain pipe 21, and the drain pipe 21 communicates with the port 11. The air conditioner outdoor unit 1 is also provided with a fresh air collecting pipe 12 , and the port 11 communicates with the drain pipe 21 through the fresh air collecting pipe 12 . An anti-return air baffle 121 is arranged on the fresh air collecting pipe to prevent the indoor air from returning to the air in reverse.

After the air conditioner turns on the fresh air mode, the outdoor fan of the air conditioner is reversed, and the internal pressure decreases, and the outdoor fresh air is pressed into the interior of the air conditioner outdoor unit 1 through the port 11, and the condensed water in the condensed water storage area is used for a temperature treatment (for example, outdoor in summer) When the ambient temperature is high, the fresh air is cooled; when the outdoor ambient temperature is low in winter, the fresh air is heated). The fresh air that has undergone primary temperature treatment is sent to the indoor unit 2 of the air conditioner through the fresh air collecting pipe 12, and the fresh air is subjected to secondary temperature treatment through the drainage in the drain pipe 21 to reduce the influence of the outdoor environment on the temperature of the fresh air, thereby reducing the impact of the fresh air mode of the air conditioner on the indoor environment.

As shown in FIG. 3 , an embodiment of the present disclosure provides a control method for air conditioner supplying fresh air, including the following steps:

S301: Obtain the outdoor ambient temperature when the air conditioner is in the fresh air mode.

In practical applications, users can turn on the fresh air function of the air conditioner through remote control, voice or other intelligent control methods. The air conditioner can obtain the outdoor ambient temperature through a temperature measuring instrument installed in the outdoor environment, or can also obtain the outdoor ambient temperature at the current geographic location through a network.

S302: When the outdoor ambient temperature is lower than the first preset ambient temperature, control the reverse rotation of the outdoor fan of the air conditioner, and control the forward rotation of the indoor fan of the air conditioner, so that the fresh air is sent to the room through the condensed water storage area and the drain pipe in sequence.

Here, the value of the first preset ambient temperature is [40°C, 44°C], for example, 40°C, 41°C, 42°C, 44°C. In this solution, only the outdoor fan and the indoor fan are used to send fresh air, so the outdoor ambient temperature has a certain influence on the quality of the air-conditioning fresh air. When the outdoor ambient temperature exceeds the first preset ambient temperature, it is regarded as a high-temperature environment. At this time, the outdoor fan is reversed and the indoor fan is rotating forward to send fresh air. A preset ambient temperature is regarded as a suitable environment, and the outdoor fan is reversed and the indoor fan is rotated forward to realize the air conditioner to send fresh air. In this way, the normal operation of the fresh air supply function of the air conditioner can be guaranteed as much as possible, and the fresh air quality of the fresh air supply by the air conditioner can be improved.

Using the control method for fresh air supply provided by the embodiments of the present disclosure, when the air conditioner turns on the fresh air mode, it first judges the suitability of the outdoor ambient temperature. Sent to the room through the condensed water storage area and the drain pipe in turn, and the secondary temperature treatment (cooling/heating) of the fresh air through the condensed water and the drainage in the drain pipe reduces the influence of the outdoor environment on the temperature of the fresh air, thereby reducing the impact of the fresh air on the indoor air. The influence of air temperature. In this way, while improving the freshness of indoor air, the excessive influence of outdoor fresh air on the indoor environment is avoided, thereby effectively improving user comfort and improving user experience.

As shown in FIG. 4 , the control method for the air conditioner to supply fresh air provided by the embodiment of the present disclosure includes the following steps:

S401: Obtain the outdoor ambient temperature when the air conditioner is in the fresh air mode.

S402: When the outdoor ambient temperature is lower than the first preset ambient temperature, control the outdoor fan of the air conditioner to reverse at the first rotational speed, and control the indoor fan of the air conditioner to rotate forward at the second rotational speed, so that the fresh air passes through the condensed water area in sequence and drain pipe to the interior.

Wherein, the first rotational speed and the second rotational speed satisfy the following relationship:

r ₂ =r ₁ +Δr

Wherein, r ₁ is the first rotational speed, r ₂ is the second rotational speed, and Δr is the compensation rotational speed.

After the air conditioner turns on the fresh air mode, control the indoor fan of the air conditioner to rotate forward at the second speed greater than the speed of the outdoor fan of the air conditioner, so that the pressure change caused by the rotation of the indoor fan of the air conditioner is greater than the pressure change caused by the rotation of the outdoor fan. The pressure of the machine changes in steps, which helps the fresh air to fully contact with the moisture in the condensate water area and the drain pipe when it passes through the condensate water area and the drain pipe in sequence, so as to better treat the temperature of the fresh air and reduce the impact of the fresh air on the air. Influence of indoor air temperature.

Optionally, the compensation rotation speed is determined as follows: based on the outdoor ambient temperature, the rotation speed corresponding to the outdoor ambient temperature is determined by looking up a rotation speed correlation table; and the rotation speed corresponding to the outdoor ambient temperature is used as the compensation rotation speed.

After the outdoor ambient temperature is obtained, the rotational speed corresponding to the outdoor ambient temperature (compensated rotational speed) is determined by looking up the rotational speed correlation table. Table 1 below shows an optional correlation table between the outdoor ambient temperature and the rotational speed:

Table 1 Correlation between outdoor ambient temperature and rotational speed

In the rotational speed correlation table, the greater the temperature difference between the real-time outdoor ambient temperature and the preset temperature (for example, 24°C), the greater the rotational speed (compensated rotational speed). Let the temperature difference be positively correlated. In this way, with the abnormal increase/decrease of the outdoor ambient temperature, the step change range of the pressure from the air-conditioning indoor unit to the air-conditioning outdoor unit is increased, which can adaptively prolong the contact between the fresh air and the moisture in the condensed water storage area and the drain pipe Time, better temperature treatment of fresh air, reduce the impact of fresh air on indoor temperature, thereby improving user comfort.

Using the control method for air conditioner supplying fresh air provided by the embodiments of the present disclosure, after the air conditioner turns on the fresh air mode, the indoor fan of the air conditioner is controlled to rotate forward at a second speed greater than the speed of the outdoor fan of the air conditioner, so that the pressure change caused by the rotation of the indoor fan of the air conditioner is greater than The pressure change caused by the rotation of the outdoor fan, the pressure from the indoor unit of the air conditioner to the outdoor unit of the air conditioner changes step by step, which helps the fresh air to be in the condensate water area and the drain pipe when the fresh air passes through the condensate water area and the drain pipe in turn. The moisture in the room can be fully contacted, the temperature of the fresh air can be better treated, and the influence of the fresh air on the indoor temperature can be reduced, thereby improving the user's comfort.

As shown in FIG. 5 , the control method for the air conditioner to supply fresh air provided by the embodiment of the present disclosure includes the following steps:

S501: Obtain the outdoor ambient temperature when the air conditioner is in the fresh air mode.

S502: When the outdoor ambient temperature is lower than the first preset ambient temperature, and the outdoor ambient temperature is higher than the second preset ambient temperature, control the outdoor fan to rotate intermittently, and control the indoor fan to rotate forward intermittently, so that the fresh air passes through the condensation in sequence Shuitun water area and drainage pipes are sent indoors.

Wherein, the second preset ambient temperature is lower than the first preset ambient temperature. The value of the second preset ambient temperature is [33°C, 36°C], for example, 33°C, 34°C, 35°C, 36°C.

After the air conditioner turns on the fresh air mode, when the outdoor ambient temperature is lower than the first preset ambient temperature, and the outdoor ambient temperature is greater than the second preset ambient temperature, that is, when the outdoor ambient temperature is relatively high, the outdoor fan and the indoor fan are controlled. Intermittent operation helps the fresh air to fully contact with the moisture in the condensed water area and the drain pipe when it passes through the condensate water area and the drain pipe in turn, so as to better treat the temperature of the fresh air and reduce the impact of the fresh air on the indoor temperature .

Optionally, controlling the intermittent reverse rotation of the outdoor fan and the intermittent forward rotation of the indoor fan includes: controlling the reverse rotation of the outdoor fan according to the first interval, and controlling the reverse rotation of the indoor fan according to the second interval; wherein, the first interval greater than the second interval duration.

After the air conditioner turns on the fresh air mode, when the outdoor ambient temperature is relatively high, control the intermittent operation of the outdoor fan and the indoor fan, and make the first interval of the outdoor fan longer than the second interval of the indoor fan, so that the indoor fan of the air conditioner rotates with The pressure change brought by the air conditioner is greater than the pressure change caused by the rotation of the outdoor fan. The pressure change from the indoor unit of the air conditioner to the outdoor unit of the air conditioner is a stepwise change, which helps the fresh air to pass through the condensed water storage area and the drain pipe in sequence, and it is in the condensed water storage area. The moisture in the area and the drainage pipe can be fully contacted, the temperature of the fresh air can be better treated, and the influence of the fresh air on the indoor temperature can be reduced.

Using the control method for the air conditioner to supply fresh air provided by the embodiments of the present disclosure, after the air conditioner turns on the fresh air mode, when the outdoor ambient temperature is lower than the first preset ambient temperature, and the outdoor ambient temperature is greater than the second preset ambient temperature, that is When the outdoor ambient temperature is relatively high, control the intermittent operation of the outdoor fan and the indoor fan. When the fresh air passes through the condensed water storage area and the drain pipe in sequence, the contact time between the fresh air and the moisture in the condensed water storage area and the drain pipe is prolonged. It helps the fresh air to fully contact with the moisture in the condensed water area and the drain pipe, better temperature-treats the fresh air, reduces the impact of the fresh air on the indoor temperature, and improves user comfort.

In some embodiments, the control method for the air conditioner to supply fresh air further includes: after the air conditioner operates in the fresh air mode, determining the room temperature variation during the fresh air mode operation; using the room temperature variation to correct the current target temperature of the air conditioner to Determine the final target temperature of the air conditioner; control the air conditioner to operate according to the final target temperature.

The room temperature change during the fresh air mode operation can be determined by using a temperature measuring instrument with high sensitivity, or the heat Q sent into the room by the air conditioner when the air conditioner is running in the fresh air mode can be calculated first, and then the room temperature change can be calculated according to the size of the room quantity. Specifically, the room temperature change Δt can be calculated according to the heat formula (Q=CMΔt), where C is the specific heat capacity of air at the current temperature, M is the air mass, and Δt is the room temperature change. The air mass M can be calculated according to the formula M=ρ×V, where ρ is the air density of the room and V is the volume of the room.

This scheme uses the pressure change caused by the rotation of the outdoor fan and the indoor fan to send the fresh air from the outside to the room. After the fresh air mode of the air conditioner is finished, it will have a certain impact on the initial temperature in the room. Therefore, after the fresh air mode is running, using the room temperature variation to correct the current target temperature of the air conditioner to determine the final target temperature of the air conditioner will help to adjust the room temperature to the most suitable temperature environment for the user faster and better. To meet the user's temperature adjustment needs.

Optionally, using the room temperature variation to correct the current target temperature of the air conditioner to determine the final target temperature of the air conditioner includes:

When the air conditioner is in heating mode, determine the final target temperature according to the following formula:

T=T ₀ +ΔT

Among them, T is the final target temperature, T ₀ is the current target temperature, and ΔT is the variation of room temperature.

For example, when the air conditioner is in heating mode, if the current target temperature T ₀ of the air conditioner is 25°C and the room temperature variation ΔT is 0.5°C, the final target temperature of the air conditioner is 25.5°C.

When the air conditioner is in cooling mode, determine the final target temperature according to the following formula:

T=T ₀ -ΔT

For example, when the air conditioner is in cooling mode, if the current target temperature T ₀ of the air conditioner is 25°C and the room temperature variation ΔT is 0.5°C, the final target temperature of the air conditioner is 24.5°C.

As shown in FIG. 6 , the control method for the air conditioner to supply fresh air provided by the embodiment of the present disclosure includes the following steps:

S601: Obtain the outdoor ambient temperature when the air conditioner is in the fresh air mode.

S602: When the outdoor ambient temperature is lower than the first preset ambient temperature, control the reverse rotation of the outdoor fan of the air conditioner, and control the forward rotation of the indoor fan of the air conditioner, so that the fresh air is sent to the room through the condensed water storage area and the drain pipe in sequence.

S603: After the air conditioner operates in the fresh air mode, determine the room temperature variation during the fresh air mode operation.

S604: Correct the current target temperature of the air conditioner by using the room temperature change amount to determine the final target temperature of the air conditioner.

S701: Obtain the space occupancy volume ratio of the target object in the preset space.

Here, the preset space is a geographic space where the air conditioner performs air conditioning, such as a room where the air conditioner is located. The space occupancy volume ratio of the target object can be calculated according to the following formula:

A=N/V

Wherein, A is the space occupancy volume ratio of the target object, N is the number of target objects in the preset space, and V is the volume of the preset space.

Optionally, the target objects include human bodies and other creatures; obtaining the space occupancy volume ratio of the target objects in the preset space includes:

is the weight of the floor area ratio occupied by other biological spaces,

Other creatures here can be cats, dogs, pigs and other household pets. In the space environment where people and pets coexist, the space occupancy volume ratio weight is introduced to comprehensively calculate the space occupancy volume ratio of the target object, and then the space occupancy volume ratio is used to measure the demand for fresh air in the space, which can more accurately control the fresh air of the air conditioner The opening or closing of the mode, while meeting the fresh air demand of the human body and pets, reduces the frequency of the fresh air mode operation, thereby reducing the impact of the air conditioner's fresh air mode operation on the normal cooling/heating air conditioning of the air conditioner.

Optionally, determine the weight of the space occupancy volume ratio of other organisms in the following manner: obtain the average volume of other organisms; based on the average volume, determine the weight of the space occupancy volume ratio corresponding to the average volume through the weight relationship table of the space occupancy volume ratio; The weight of the space occupancy volume ratio corresponding to the average volume is used as the weight of other biological space occupancy volume ratios.

After obtaining the average volume of other organisms, the weight of the space occupancy volume ratio corresponding to the average volume is determined by looking up the space occupancy volume ratio weight correlation table. The following table 2 shows an optional correlation table between the average volume of other organisms and the weight of the space occupancy volume ratio:

Table 2 The relationship between the average volume of other organisms and the weight of the space occupancy volume ratio

In general, the larger the organism, the greater its oxygen consumption and its ability to produce carbon dioxide and other air waste. Therefore, in the space occupancy volume ratio, the weight of the space occupancy volume ratio is positively correlated with the average volume of other organisms, which can more accurately measure the fresh air demand of the target object in the space, so as to more accurately control the opening or closing of the air conditioning fresh air mode. closure.

S702: When the space occupancy volume ratio is greater than the preset space occupancy volume ratio, control the air conditioner to turn on the fresh air mode.
