Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a control method for introducing fresh air into an air conditioner, which can be applied to an intelligent terminal. The smart terminal may be, but is not limited to, various personal computers, notebook computers, mobile phones, tablet computers, in-vehicle computers, AI robots, air conditioners, and portable wearable devices. The intelligent terminal adopts a multi-core processor. The processor of the terminal may be at least one of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a Video Processing Unit (VPU), and the like.
The air conditioner compressor functions to compress a driving refrigerant in an air conditioner refrigerant circuit. An air conditioner compressor is generally installed in an outdoor unit. The air conditioner compressor extracts the refrigerant from a low-pressure area, compresses the refrigerant and sends the compressed refrigerant to a high-pressure area for cooling and condensation, heat is emitted into air through the radiating fins, the refrigerant is changed from a gas state into a liquid state, and the pressure is increased. The working circuit of the air-conditioning compressor is divided into an evaporation zone (low-pressure zone) and a condensation zone (high-pressure zone). The indoor unit and the outdoor unit of the air conditioner belong to a low pressure region or a high pressure region, respectively (depending on the operating state). The refrigerant flows from the high-pressure area to the low-pressure area and is sprayed into the evaporator through the capillary tube, the pressure of the flowing liquid refrigerant is suddenly reduced, the liquid refrigerant immediately becomes gaseous, and a large amount of heat in the air is absorbed through the radiating fins. Therefore, the air conditioner compressor continuously works, and heat at one end of the low-pressure area is continuously absorbed into the refrigerant and then is sent to the high-pressure area to be diffused into the air, so that the air conditioner compressor plays a role in adjusting the air temperature.
The air conditioner is stopped when the indoor temperature reaches the temperature set by the user, the air conditioner compressor is stopped to stop working, when the indoor temperature rises to a certain temperature, the air conditioner compressor is restarted and repeated, but in the prior art, the air conditioner compressor is frequently started and stopped due to too high or unreasonable temperature setting, and the service life of the compressor is shortened.
According to the control method for introducing the fresh air into the air conditioner, the intelligent terminal and the storage medium, the temperature in a room is not changed rapidly by adjusting that the air output of the air conditioner is smaller than a preset air output threshold value and the introduced fresh air and the refrigerating capacity or heating capacity output by the air conditioner are neutralized, and frequent shutdown of an air conditioner compressor caused by the fact that the current indoor temperature quickly reaches the target temperature is avoided; meanwhile, fresh air is introduced into the sealed environment for a long time, so that indoor air can be fresh, breeding of germs can be reduced, and indoor moisture regain can be prevented.
Various non-limiting embodiments of the present invention are described in detail below with reference to the accompanying drawings.
An exemplary method:
referring to fig. 1, the present invention provides a method for controlling fresh air introduced into an air conditioner, including:
step S100: and acquiring the fresh air threshold temperature of the air conditioner.
Specifically, referring to fig. 2, the step S100 includes:
step S101: and acquiring the set temperature of the air conditioner and the running mode of the air conditioner.
Specifically, the set temperature is an indoor temperature set by a user, and is an indoor temperature which the user wants to maintain, the user can set the indoor temperature through an air conditioner remote controller and an intelligent electronic device connected with the air conditioner, such as a mobile phone, and the like, the air conditioner operation mode includes a cooling mode or a heating mode, for example, the cooling mode is often used in summer and the heating mode is used in winter, and the user can select the air conditioner operation mode through the air conditioner remote controller and the intelligent electronic device connected with the air conditioner, such as the mobile phone.
Step S102: and acquiring a preset target adjusting temperature and a preset fresh air adjusting temperature of the air conditioner.
Specifically, the target adjustment temperature is an equivalent difference between the target temperature and the set temperature set by the user, and may be set by factory setting, for example, when the set target adjustment temperature is 2 degrees celsius, the difference between the set temperature and the target temperature is 2 degrees celsius regardless of the degree of the set temperature set by the user. The fresh air adjusting temperature is an equivalent difference value between a fresh air threshold temperature of the air conditioner for introducing fresh air and a set temperature set by a user, or an equivalent difference value between a fresh air threshold temperature of the air conditioner for introducing fresh air and a target temperature, and the fresh air adjusting temperature is not specifically limited in the invention and can be limited in the field-outgoing setting, for example, when the fresh air adjusting temperature is an equivalent difference value between the fresh air threshold temperature of the air conditioner for introducing fresh air and the target temperature, the fresh air adjusting temperature can be set to be 1; when setting up new trend temperature regulation is the difference of the equivalent between the new trend threshold value temperature that the air conditioner lets in the new trend and the settlement temperature that the user set up, can set for new trend temperature regulation and be 1, need explain that in this embodiment the difference be the absolute value.
Step S103: determining a target temperature of the air conditioner based on the set temperature, the air conditioner operation mode, and the target regulation temperature.
Specifically, the target temperature is a temperature value at which the indoor temperature reaches a certain temperature at which the air conditioner compressor is stopped, the target temperature may be a temperature value greater than or less than the set temperature, for example, when the air conditioner is in a cooling state, the set temperature is set to 25 degrees celsius, when the target adjustment temperature is 2 degrees celsius, the target temperature is a difference value between the set temperature and the target adjustment temperature of 2 degrees celsius, and the target temperature is 23 degrees celsius.
Step S104: and determining the fresh air threshold temperature of the air conditioner based on the target temperature, the air conditioner operation mode and the fresh air adjusting temperature. The air conditioner operation mode comprises a refrigeration mode and a heating mode, when the air conditioner operation mode is the heating mode, the fresh air threshold temperature is smaller than the target temperature, and when the air conditioner operation mode is the refrigeration mode, the fresh air threshold temperature is larger than the target temperature.
Specifically, in this embodiment when the fresh air temperature regulation temperature lets in the equivalent difference between the new trend threshold value temperature and the target temperature of new trend for the air conditioner, based on the above-mentioned example, when the air conditioner belongs to the refrigeration state, the target temperature is 23 degrees centigrade or 27 degrees centigrade, when the new trend temperature regulation is 1, work as when the target temperature is 23 degrees centigrade, the new trend threshold value temperature does the sum of target temperature and new trend temperature regulation, the new trend threshold value temperature is 24 degrees centigrade this moment, will open the new trend system and let in the new trend when the indoor temperature reaches 24 degrees centigrade, avoids the indoor temperature to reach the target temperature has caused the air condition that air condition compressor shut down but has not let in the new trend to take place. At this moment, the fresh air threshold temperature is greater than the target temperature, specifically, the temperature difference between the target temperature and the fresh air threshold temperature is 0.5-3 ℃, so that the introduction of fresh air is prevented too early, and the introduction of fresh air is more reasonable. The fresh air threshold temperature can be between the target temperature and the set temperature, or can be set as the fresh air threshold temperature, the target temperature and the fresh air threshold temperature are intermediate points between the target temperature and the set temperature, and the target temperature and the fresh air threshold temperature are respectively located on two sides of the set temperature, for example, the fresh air threshold temperature is 25 ℃, the set temperature is 24 ℃ and the target temperature is 22 ℃, so as to ensure that the fresh air threshold temperature is the temperature when the indoor temperature does not reach the target temperature, and the invention is not specifically limited. When the air conditioner belongs to the state of heating, based on above-mentioned principle, under the heating mode, work as when the settlement temperature is 25 degrees centigrade, the target temperature can be 23 degrees centigrade or 27 degrees centigrade, when new trend temperature regulation is 1, work as when the target temperature is 27 degrees centigrade, new trend threshold temperature does the difference of target temperature and new trend temperature regulation, new trend threshold temperature is 26 degrees centigrade this moment, will open new trend system and let in the new trend when the indoor temperature reaches 26 degrees centigrade, at this moment, new trend threshold temperature is less than the target temperature, in order to avoid the indoor temperature to reach the target temperature has caused the air conditioner compressor to shut down but has not let in the condition of new trend and has taken place. Specifically, the temperature difference between the target temperature and the fresh air threshold temperature is 0.5-3 ℃, so that the situation that fresh air is introduced too early is avoided, and the introduction of the fresh air is more reasonable.
And calculating to obtain a fresh air threshold temperature according to the working state of the air conditioner and the set temperature by acquiring the air conditioner operation mode and the set temperature, so that the fresh air threshold temperature is matched with the air conditioner operation mode and the set temperature. Corresponding calculation can be carried out on the basis of the set temperature and the air conditioner operation mode by setting the adjusting target adjusting temperature and the fresh air adjusting temperature, so that the obtained fresh air threshold temperature is more accurate.
Step S200: and monitoring the current indoor temperature, and controlling the air conditioner to introduce fresh air when the current indoor temperature reaches the fresh air threshold temperature.
Further, in the present embodiment, the control method further includes: and when the current indoor temperature reaches the fresh air threshold temperature, adjusting the air output of the air conditioner to be smaller than a preset air output threshold value.
Specifically, the air conditioner itself has a high (maximum output air volume), a medium (second maximum output air volume), a low (minimum output air volume) or a first (minimum output air volume), a second (second minimum output air volume), a third (third minimum output air volume) output air volume mode, wherein the blocking mode and the first shift are both low air modes, and the low air mode is the mode with the minimum air volume of the air conditioner. The air outlet threshold value can be one of the wind speed values, for example, the air outlet threshold value is set to be a middle level, when the current indoor temperature reaches the fresh air threshold value temperature, the air conditioner is adjusted to be a low wind level, at the moment, the air quantity output by the air conditioner to the indoor is minimum, the cold quantity or the heat quantity output by the air conditioner to the indoor is reduced to the maximum extent, the problems that the air conditioner consumes too much electricity due to too much cold quantity or heat quantity input into the indoor of the air conditioner and the air conditioner compressor frequently reaches a target temperature to stop the air conditioner due to the rapid reaching of the indoor temperature (the stop of reaching the temperature means that the compressor stops and is closed when the internal temperature reaches the target temperature) are avoided, if too much cold quantity or heat quantity is input, a large amount of fresh air output allowance is generated, the allowance can be balanced by inputting a large amount of fresh air, the air is overhigh, and a large amount of consumed air is input, the fresh air can also cause the fresh air passing time period to be lengthened, the period for causing the shutdown of the air conditioner compressor becomes short. In other embodiments of the present invention, the air outlet threshold may not be set to be a middle gear, and may be set to be a high gear, and the air conditioner may be switched to be a middle gear or a low gear, which is not limited in this application.
Specifically, referring to fig. 3, the step S200 includes:
the step S201: monitoring the current indoor temperature;
specifically, the current indoor temperature is the indoor temperature for implementing acquisition, and real-time acquisition and monitoring can be performed through the temperature sensor.
Step S202: and when the current indoor temperature reaches the fresh air threshold temperature, adjusting the air output of the air conditioner to be smaller than a preset air output threshold value.
Specifically, the air conditioner. For example, based on the above, the low wind mode (low wind gear), the medium wind mode (medium wind gear) and the high wind mode (high wind gear) are divided, and the low wind mode is the mode with the minimum air conditioner air output. When the current indoor temperature reaches the fresh air threshold temperature, for example, based on the above example, when the fresh air threshold is also 24 degrees celsius, the current indoor temperature is monitored, and when the temperature changes to 24 degrees celsius, the first fresh air is introduced and the air-conditioning mode is switched to the low-air mode to keep the current indoor temperature stable, the output of the heat or the cold of the air-conditioning is reduced by switching the air-conditioning to the low-air mode, the decrease or the increase of the indoor temperature is reduced, and the output temperature of the air-conditioning is neutralized by introducing the first fresh air at the same time. It can be understood that when the air conditioner is used for refrigeration, the outdoor temperature is higher than the air outlet temperature of the air conditioner, and the air flows with the two temperatures are mixed to exchange energy to realize temperature neutralization, so that the output of heat or cold of the air conditioner is further reduced, and the reduction or increase of the indoor temperature is further reduced. Specifically, the air outlet of the fresh air system can be communicated with an air outlet of the air conditioner, cold air or hot air input into the air conditioner is mixed with introduced fresh air to carry out heat exchange so as to raise or lower the temperature of the air in the output chamber of the air conditioner, and therefore the condition that the air conditioner compressor is stopped due to the fact that the indoor temperature is sharply reduced to reach the target temperature is avoided.
By adjusting the air output of the air conditioner to be smaller than a preset air output threshold value, in the embodiment, the preset air output threshold value is a medium wind mode (medium wind gear), and the air output mode of the air conditioner is adjusted to be a low wind mode at the moment, namely, the air output of the air conditioner is adjusted to be the minimum low wind gear, so that the refrigerating or heating output of the air conditioner is reduced, meanwhile, the first fresh air is introduced to perform the refrigerating or heating output neutralization of the air conditioner, the heat exchange of a room is stable, the room temperature can be kept stable near a set temperature after the fresh air is introduced and the air conditioner mode is switched, and the air conditioner compressor is prevented from being stopped due to the fact that the indoor temperature continuously drops or rises to reach the target temperature.
Step S203: and acquiring a preset normal temperature floating range value of the air conditioner and preset constant temperature duration.
Specifically, the normal range value of the preset temperature normal floating range is the normal range of the indoor temperature change value after the fresh air is introduced indoors and the air conditioner is adjusted to the air outlet mode of the low air mode, based on the above description, when the fresh air is introduced indoors and the air outlet mode of the air conditioner is switched to the low air mode, the difference between the indoor temperature and the fresh air threshold temperature is not large (due to the fact that the delay or the error of fresh air adjustment is not consistent), the temperature after the fresh air is introduced indoors and the air conditioner mode is switched is taken as a basic point, the reasonable range of the temperature up-and-down floating of the basic point is set as the normal temperature floating range value, and the range value can be set by debugging according to assembly or product debugging. It can be understood that the poor use feeling of a user is not caused by the fact that the indoor temperature value floats up and down after fresh air is introduced indoors and the air conditioning mode is switched, and the temperature floating parameter is preset to be a normal temperature floating range value.
The preset constant temperature duration is the duration of the indoor temperature floating within the normal temperature floating range value after the fresh air is introduced into the room and the air-conditioning air-out mode is switched into the low air mode, the constant temperature is not literally constant temperature, in the invention, the temperature of the indoor temperature floating within the normal temperature floating range value after the fresh air is introduced into the room and the air-conditioning air-out mode is switched can be defined as the constant temperature, namely the temperature of the indoor temperature can be understood as constant temperature when the fresh air is introduced into the room and the indoor temperature floats within the normal temperature floating range value after the air-conditioning mode is switched, the duration of the constant temperature floating within the normal floating range value is the constant temperature duration, and the preset constant temperature duration is the small or optimal duration of the indoor temperature floating within the normal temperature floating range value after the fresh air is introduced into the room and the air-conditioning air-out mode is switched, which is allowed by factory setting or allocating components, the setting may be made according to the debugging result.
Step S204: monitoring a first indoor temperature after first fresh air is introduced and an air conditioning mode is switched to a low air mode, and judging whether the duration of the first indoor temperature in the normal temperature floating range value is matched with preset constant temperature duration.
Specifically, the first indoor temperature is the first indoor temperature after the first fresh air is introduced and the air-out mode of the air conditioner is switched to the low air mode (low wind gear). If the floating time of the first indoor temperature in the normal temperature floating range value exceeds the preset constant temperature time, the time of the first indoor temperature in the normal temperature floating range value is considered to be matched with the preset constant temperature time, otherwise, the time is not matched, for example, the preset constant temperature time is 30 minutes, when the first indoor temperature is floated within the normal temperature floating range value for 35 minutes, the duration of the first indoor temperature within the normal temperature fluctuation range value is considered to match a preset constant temperature duration, keeping the state of introducing fresh air unchanged and continuously monitoring the indoor temperature change after the first fresh air is introduced, in other embodiments of the present invention, it can also be considered that the time length of the first indoor temperature within the temperature normal floating range value is equal to or exceeds the preset constant temperature time length, and then the time length of the first indoor temperature within the temperature normal floating range value is matched with the preset constant temperature time length. At the moment, the first fresh air is continuously introduced, and the air conditioner is in a low-wind mode.
Step S205: when first indoor temperature is in duration in the normal floating range value of temperature with when not matching, monitoring and appearing when the duration of predetermined constant temperature first indoor temperature reaches when the compressor of target temperature space-time pressure is shut down, control the first new trend of air conditioner switching is the second new trend, the wind speed of second new trend is greater than the wind speed of first new trend.
Work as the length of time that first indoor temperature floated in the normal floating range value of temperature is less than when the predetermined constant temperature then first indoor temperature is in the length of time in the normal floating range value of temperature is not matched with when the predetermined constant temperature is long and is monitored and appear reaching the warm machine halt, then explains that the heat that cold wind or hot-blast in the air conditioner output room still is too big, lets in first new trend still can not neutralize the unnecessary heat or the cold volume of air conditioner output, switches over this moment first new trend is the second new trend, the wind speed of second new trend is greater than the wind speed of first new trend, and then realizes letting in more cold wind or hot-blast surplus that go to neutralize the hot-blast or cold wind of air conditioner output through the new trend, realizes indoor temperature's stability.
By monitoring the first fresh air introduced and adjusting the first indoor temperature after the air output of the air conditioner is less than the preset air output threshold value, judging whether the time length of the first indoor temperature in the normal temperature floating range value is matched with a preset constant temperature time length or not, judging whether the energy contained in the introduced first fresh wind energy and the energy output by the air conditioner can be neutralized to balance the allowance output to the indoor by the air conditioner in the same period or not, and keeping the balance temperature of the current indoor temperature, if the time length of the first indoor temperature within the normal temperature floating range value does not match the preset constant temperature time length, the input of the first fresh air is too little to stabilize the space-time temperature, at the moment, the second fresh air is replaced to adjust the fresh air in time, the air conditioner is prevented from stopping when reaching the temperature, the temperature-reaching shutdown is shutdown of the pressure-regulating compressor when the first indoor temperature reaches the target temperature.
On the basis of the above embodiment, referring to fig. 4, the step S200 in this embodiment further includes:
step S206: when the first indoor temperature is in the time length in the normal floating range value of temperature with when the time length of predetermined constant temperature is not matched, and not monitor and appear the first indoor temperature reaches when the compressor of the air-time regulator of target temperature shuts down, control the air conditioner stops letting in first new trend.
If first indoor temperature is in when the long time of the normal floating range value of temperature is not matched with and does not appear reaching the phenomenon of warm shut down long with predetermined constant temperature, then explain the input of first new trend too much, unnecessary air conditioner exports indoor surplus, causes the influence to indoor refrigeration or heating this moment, through stopping letting in first new trend for the new trend application is more reasonable, and is concrete, the stopping of first new trend lets in can be realized through controlling the new trend fan or through closing the new trend entry, in this embodiment, the stopping of first new trend lets in and rotates the realization through closing the new trend fan.
Further, on the basis of the above embodiment, the above steps S204 and S206 are continuously repeated, the indoor temperature is monitored, and whether the second fresh air is continuously switched to the third fresh air is judged according to the monitoring result, the wind speed of the third fresh air is greater than the wind speed of the second fresh air until the time length of the indoor temperature within the normal temperature floating range value matches the preset constant temperature time length or the maximum level of the wind speed is reached, and the like. Specifically, in the above embodiment, the first fresh air, the second fresh air, and the third fresh air are divided mainly according to the rotation speed of the fresh air fan, and specifically, the division may be performed with reference to the rotation speed of the air conditioner fan, for example, the rotation speed of the fan of 1 air conditioner is 1150/1050/850 for high/medium/low, the rotation speed of the fan of 1.5 air conditioners is 1350/1250/1050/850 for high/medium/low, and the division of the first fresh air, the second fresh air, and the third fresh air is set and divided according to the rotation speed of the air conditioner fan.
In other specific embodiments of the present invention, the maximum stage of the wind speed introduced into the fresh air or the wind speed introduced into the fresh air is based on only introducing the fresh air or only switching to the second fresh air, which all fall within the protection scope of the present invention, and the present invention is not limited in the specific embodiments.
Specifically, referring to fig. 5, in another embodiment of the present invention, the step S100 is similar to the above embodiment, and the step S200 includes:
step S207: monitoring the current indoor temperature.
Specifically, the current indoor temperature is the indoor temperature for implementing acquisition, and real-time acquisition and monitoring can be performed through the temperature sensor.
Step S208: when the current indoor temperature reaches the fresh air threshold temperature, the output air volume of the air conditioner is adjusted, specific heat calculation parameters are obtained, and the heat value of fresh air needing to be introduced is calculated based on the specific heat calculation parameters.
Specifically, in other embodiments of the present invention, when the current indoor temperature reaches the fresh air threshold, the output air volume of the air conditioner is adjusted to be smaller than a preset air outlet threshold; the air conditioner air. For example, the air output of the divided air conditioners according to the above embodiments is sized into a low air mode (low wind range), a medium air range mode (medium wind range), and a high air mode (high wind range), and the low air mode is the mode in which the air output of the air conditioner is the minimum. By adjusting the air output of the air conditioner to be smaller than a preset air output threshold, in this embodiment, the preset air output threshold is a medium wind mode (medium wind gear), and at this time, the air output mode of the air conditioner is adjusted to be a low wind mode, that is, the air output of the air conditioner is adjusted to be the minimum low wind gear, so that the cooling or heating output of the air conditioner is reduced, and at the same time, a first fresh air is introduced to perform the cooling or heating output neutralization of the air conditioner, so that the room heat exchange is stable, the room temperature can be kept stable around a set temperature after the fresh air is introduced and the air conditioning mode is switched, and the air conditioner compressor is prevented from being stopped when the indoor temperature continuously drops or rises to reach a target temperature. Avoiding serious power consumption. The specific heat calculation parameter can be room capacity and air specific heat at various temperatures, the specific heat can be recorded and stored through air conditioner assembly or debugging, the preset restart temperature of the air conditioner compressor after shutdown is determined based on the fresh air threshold, the restart temperature calculation method of the air conditioner can be calculated based on the target temperature or the set temperature by referring to the target temperature calculation method and the preset restart adjusting temperature. And calculating a first heat value generated when the air conditioner compressor is restarted after being stopped, and calculating a second heat value generated when the air conditioner compressor is restarted to be stopped again based on the condition that the output air quantity of the air conditioner is smaller than a preset air outlet threshold value. For example, when the air conditioner is turned on, and after the air conditioner runs for a long time H, and the indoor temperature reaches the target temperature, the air conditioner compressor is turned on again, after the time H1, the indoor environment temperature is increased or decreased from T1 (the target temperature) to Th (the Th is the temperature at which the air conditioner is turned on again), and after the time H2, the air conditioner compressor is turned on again and is turned off (no fresh air is introduced), and the first heat and the second heat can be calculated through a heat formula. The first quantity of heat is the amount of energy transferred at the indoor temperature when T1 (target temperature) rises or falls to Th (Th is temperature at which the air conditioner restarts), and the second quantity of heat is the amount of cold or heat produced by the air conditioner that Th (Th is temperature at which the air conditioner restarts) rises or falls to T1 (target temperature), which Th may be the same as the fresh air threshold temperature in the present embodiment. In other embodiments of the present invention, Th may be greater than or less than the fresh air threshold temperature, and the present invention is not limited thereto. Calculating the difference value of the first heat value and the second heat value to obtain a fresh air heat value, wherein the difference value of the first heat value and the second heat value is calculated as the difference value of the first heat value and the second heat value, namely the difference value of the first heat value and the second heat value is the difference value of the heat or the cold input by the air conditioner after the heat or the cold absorbed by the outside factors in the room is balanced, the air conditioner compressor is stopped because the indoor temperature quickly reaches the target temperature due to the existence of the residual heat or the cold or the continuous change of the indoor temperature, and the indoor temperature is constant by balancing the residual heat or the cold through introducing fresh air, so that the air conditioner compressor is prevented from stopping at the temperature.
Step S209: and controlling the air conditioner to introduce fresh air based on the fresh air calorific value.
Specifically, in the present embodiment, the fresh air comes from outdoors, and by acquiring the current outdoor temperature and the fresh air fan parameter, the rotation speed value of the fresh air fan is calculated based on the outdoor temperature, the fresh air fan parameter and the fresh air heat value; according to the formula: q fresh air (ha1-ha2)/Vn (1+ Wn); the rotating speed of the fresh air fan is obtained by q being A1V, ha1 is an enthalpy value corresponding to the outdoor environment temperature T4, ha2 is an enthalpy value corresponding to T2 (fresh air threshold temperature), and Vn is the indoor environment air specific volume; wn is the indoor ambient air humidity; after the air conditioner compressor is stopped at a temperature and restarted for two periods, when the air conditioner is restarted and operates, and the indoor environment temperature reaches a set temperature T2 (fresh air threshold temperature), the fresh air fan is started and operates at the calculated rotating speed, outdoor air enters an indoor air return opening after being filtered, is cooled or heated by an evaporator and then is blown into a room, the temperature of the room is maintained at the set temperature T2, and the air conditioner compressor is prevented from being stopped frequently.
Step S210: acquiring a preset fresh air closing temperature of the air conditioner; and monitoring the indoor temperature of the fresh air introduced based on the calorific value of the fresh air, and controlling the air conditioner to stop introducing the fresh air when the indoor temperature of the fresh air reaches the closing temperature of the fresh air.
Specifically, through monitoring the fresh air inlet indoor temperature after the fresh air is introduced based on the fresh air calorific value so as to keep the current indoor temperature stable, and whether the judging device reaches the preset fresh air closing temperature or not can be timely used for closing and controlling the introduced fresh air, so that the influence on the refrigeration or heating effect of the air conditioner due to too much introduced fresh air is avoided.
The invention provides a control method for introducing fresh air into an air conditioner, which comprises the steps of acquiring a fresh air threshold temperature, neutralizing introduced fresh air and refrigerating capacity or heating capacity output to a room by the air conditioner when the current indoor temperature is monitored to reach the fresh air threshold temperature, stabilizing the temperature in the room near the fresh air threshold value and preventing the temperature in the room from continuously and rapidly changing, and avoiding frequent shutdown of an air conditioner compressor when the current indoor temperature quickly reaches a target temperature; setting the fresh air threshold temperature as the temperature when the indoor temperature does not reach the target temperature; the air conditioner compressor is ensured not to be stopped after reaching the temperature and not filled with fresh air. Meanwhile, fresh air is introduced into the sealed environment for a long time, so that indoor air can be fresh, breeding of germs can be reduced, and indoor moisture regain can be prevented.
