The invention also provides a control method of the fresh air machine and air conditioner linkage system, referring to fig. 1, in an embodiment, the fresh air machine and air conditioner linkage system provided by the invention comprises a fresh air machine and an air conditioner, and the control method comprises the following steps:
step S10, when the air conditioner is in the cooling mode, detecting the humidity of the indoor air, and judging whether the humidity of the indoor air is higher than a first preset value;
the control method of the fresh air fan and the air conditioner linkage system is suitable for controlling the operation of the air conditioner and the fresh air fan according to the indoor and outdoor humidity and the indoor temperature when the indoor air conditioner is in a refrigeration mode so as to adjust the indoor environment to a comfortable state. In order to ensure the operation effect of the air conditioner, the operation environment of the air conditioner is usually a sealed environment, air in the sealed environment is not circulated, and the freshness of the air is insufficient. In order to increase the freshness of the indoor air, the air freshness in the sealing environment can be increased by introducing outdoor fresh air, but the temperature of the outdoor fresh air is high, and the refrigeration effect of the air conditioner can be influenced by introducing the outdoor fresh air with high temperature. Especially, when the user enters into indoor air conditioner of opening from external environment, its first demand is the cooling, if this moment with outdoor high temperature's air introduction indoor, influence refrigeration cooling effect, can reduce user experience. In addition, the humidity in the indoor air needs to be considered because the humidity in the indoor air is low due to the passive dehumidification in the air-conditioning refrigeration process, which affects the comfort. The embodiment detects the indoor air humidity firstly, and sets a first preset value for judging the indoor air humidity, wherein the first preset value is preset and is suitable for the numerical value of the human body comfortable health standard. And judging the detected indoor air humidity and the first preset value, and controlling the operation of the air conditioner and the fresh air fan according to the judgment result.
Step S20, detecting the indoor temperature when the indoor air humidity is higher than the first preset value;
further, the detected indoor air humidity and the first preset value are judged, and when the obtained judgment result is that the indoor air humidity is higher than the first preset value, the indoor air is in a high-humidity state, the humidifying device does not need to be started for humidifying, and the refrigeration can be passively dehumidified in consideration, so that the operation of the air conditioner can be controlled to reduce dehumidification, the humidifying device is prevented from being started for humidifying, the user is prevented from adding water into the humidifying device, and the workload of the user is reduced. When the humidity of the indoor air is lower than the first preset value, the indoor air is in a low humidity state, and the humidifying device may need to be started for humidifying while the air conditioner is controlled to operate to reduce dehumidification. In addition, the indoor temperature is required to be detected, so that the situation that when the indoor temperature is high and the temperature is urgently required to be reduced, outdoor high-temperature air is introduced indoors, the cooling effect is influenced, and the user experience is reduced. Detect indoor temperature through temperature sensor, according to this indoor temperature's testing result, confirm whether can introduce the new freshness that outdoor new trend comes to increase the room air.
And step S30, determining the operation mode of the fresh air fan and the air conditioner linkage system according to the detection result of the indoor temperature, and controlling the fresh air fan and the air conditioner to operate according to the operation mode so as to introduce outdoor fresh air into the room through the air duct of the fresh air fan.
Furthermore, after the indoor temperature is detected, the operation mode of the fresh air fan and the air conditioner linkage system is determined according to the detection result, and then the operation of the fresh air fan and the air conditioner is controlled according to the determined operation mode, so that the outdoor fresh air is introduced into the room through the air duct of the fresh air fan. Wherein according to the testing result according to indoor temperature, confirm the operation mode of new fan and air conditioner linked system and include:
step S31, when the indoor temperature is higher than or equal to a second preset value, determining the operation mode of the fresh air fan and air conditioner linkage system as a first operation mode;
and step S32, when the indoor temperature is lower than a second preset value, determining the operation mode of the fresh air fan and air conditioner linkage system as a second operation mode.
In order to judge the indoor temperature, the second preset value is preset in the embodiment and is used for representing the comfortable temperature value of the human body in the air-conditioning refrigeration mode. When the temperature is higher than or equal to the temperature during air conditioning refrigeration, the temperature is too high, and the comfort level of a human body is poor; and below this temperature, it is said that the comfort of the human body is good. The temperature judging device is used for judging the temperature before the air conditioner cooling is not started and the temperature after the air conditioner cooling is started for a period of time in a room. When the indoor temperature is detected to be higher than or equal to the second preset value, which indicates that the temperature of the indoor environment is higher, it can be presumed that the primary requirement of the user is to lower the indoor temperature. Meanwhile, because the humidity of the indoor air is higher than the first preset value, the indoor air is not dry, and the air conditioner can be started to operate at the maximum frequency so as to rapidly cool. Outdoor fresh air is not introduced while the air conditioner is started for refrigeration and cooling, so that the influence of the introduced outdoor high-temperature fresh air on the refrigeration of the air conditioner is avoided; and detect indoor air humidity and outdoor air humidity after the air conditioner operation is long for a period, when indoor air humidity reduces and is less than outdoor air humidity, can introduce outdoor new trend, increase the fresh degree of indoor air when carrying out the humidification. And determining the operation mode of the fresh air fan and air conditioner linkage system corresponding to the indoor temperature higher than or equal to the second preset value as a first operation mode. And when the detected indoor temperature is lower than the second temperature, the temperature of the indoor environment is reduced through the air-conditioning refrigeration, and the human body feels more comfortable. The humidity of the indoor air can be reduced to be lower through the passive dehumidification of the refrigeration in the period of time, and the temperature reduction is no longer the first requirement at the moment, so that the operation frequency of the air conditioner is reduced, and the dehumidification is prevented from being increased. And determining the operation mode of the fresh air fan and air conditioner linkage system corresponding to the indoor temperature lower than the second preset value as a second operation mode. Controlling the operation of the fresh air machine and the air conditioner according to the determined first operation mode or the second operation mode, wherein the method comprises the following specific steps:
step S33, when the operation mode is a first operation mode, controlling the fresh air machine and the air conditioner to operate in the first operation mode, and detecting whether the indoor temperature is lower than a second preset value;
and step S34, when the indoor temperature is lower than a second preset value, switching the operation mode of the fresh air fan and air conditioner linkage system into a second operation mode, and controlling the fresh air fan and the air conditioner to operate in the second operation mode.
When the operation mode is determined to be the first operation mode, the fresh air fan and the air conditioner are controlled to operate in the first operation mode, the air conditioner is started to refrigerate, outdoor fresh air is introduced, and therefore the indoor temperature is reduced, and the freshness of indoor air is increased. And detecting the indoor temperature, and judging whether the indoor temperature is reduced to be lower than a second preset value after the air conditioner refrigerates and cools. When the temperature of the indoor air is lower than the second preset value, the indoor air temperature is reduced to meet the requirement of human comfort, the operation mode of the fresh air fan and air conditioner linkage system is switched to the second operation mode, the fresh air fan and the air conditioner are controlled to operate in the second operation mode, the air conditioner continuously performs refrigeration operation, the operation frequency is reduced, the indoor humidity is prevented from being reduced, and the user comfort is improved. And when the indoor temperature is detected and the indoor temperature is determined to be lower than a second preset value, the operation mode is directly determined to be the second operation mode, and the second operation mode is switched to without being cooled in the first operation mode. When the operation mode is determined to be the second operation mode, the fresh air fan and the air conditioner are controlled to operate in the second operation mode, the air conditioner is started to refrigerate and operate at low frequency, outdoor fresh air is introduced, the freshness and the humidity of indoor air are increased while the indoor temperature is reduced, and the comfort of a user is improved.
Further, in a second embodiment of the control method of the fresh air machine and air conditioner linkage system according to the present invention, the step of controlling the fresh air machine and the air conditioner to operate in the first operation mode includes:
step S331, starting an air conditioner refrigeration mode to operate for a preset time, and increasing the air inlet volume of the air conditioner and the opening of an electronic expansion valve in the air conditioner;
and S332, when the preset time is reached, acquiring the indoor air humidity and the outdoor air humidity, and controlling the operation of the fresh air fan according to the indoor air humidity and the outdoor air humidity.
When the operation mode of the fresh air fan and air conditioner linkage system is the first operation mode, the indoor temperature is higher than or equal to the second preset value, and the indoor temperature needs to be cooled first, so that the air conditioner refrigeration mode is started first. The dehumidification operation is carried out while the air conditioner is used for refrigerating, and the higher the running frequency is, the faster the dehumidification rate is; so as to ensure the humidity of the indoor air, it is impossible to operate at a high frequency; but low frequency operation can make the cooling effect poor. In order to compensate for the cooling effect, the air conditioner can run at a proper frequency, the air inlet volume of the air conditioner and the opening degree of the electromagnetic expansion valve are increased, the proper frequency is measured through experiments, and cooling and dehumidification can be realized at the same time. The faster the indoor air flows, the faster the cooling speed is, so the air inlet volume of the air inlet of the air conditioner can be increased. The air conditioner air inlet introduces indoor air and then comes out from the air outlet, drives the indoor air to flow and forms the wind field to rapid cooling. An electronic expansion valve is arranged in the air conditioner at the same time, and the electronic expansion valve is in an opening position before being electrified; the magnitude of the valve opening is controlled by the applied voltage, thereby adjusting the flow rate of the valve. The air conditioner is used for adjusting the flow of a refrigerant of the heat exchanger, and the larger the flow is, the better the heat exchange effect is, so that the opening degree of the electronic expansion valve is increased, and the rapid cooling is realized. And operating in the cooling mode for a preset time to reduce the indoor temperature to be lower than a second preset value meeting the human body comfort requirement. The preset time is preset according to the cooling temperature, the indoor area and the refrigerating intensity, and when the indoor area is larger and the refrigerating intensity is stronger, the preset time required for reaching the cooling degree is shorter; the smaller the corresponding indoor area is, the weaker the refrigeration intensity is, and the longer the preset time required for reaching the temperature reduction degree is. The opening degree of the air conditioner air inlet and the electronic expansion valve can be increased to increase the refrigeration intensity, the air conditioner is suitable in operation frequency, the dehumidification cannot be performed quickly, the refrigeration intensity is increased by increasing the air volume and the opening degree of the electronic expansion valve, and the balance of reducing the dehumidification and increasing the refrigeration speed is ensured. Although dehumidification can be reduced in this mode, dehumidification cannot be prevented, namely, the humidity of the indoor air can be reduced along with the operation of the air conditioner, so that when the air conditioner operates to the preset time, the indoor air humidity and the outdoor air humidity are detected, and the operation of the fresh air fan is controlled according to the detected indoor air humidity and outdoor air humidity. The motor of the fresh air machine rotates to drive the wind wheel to introduce outdoor fresh air through the air duct, and the freshness of indoor air is increased. Specifically, the step of controlling the operation of the fresh air machine according to the indoor air humidity and the outdoor air humidity comprises:
step A, judging whether the indoor air humidity is lower than the outdoor air humidity;
and step B, when the indoor air humidity is lower than the outdoor air humidity, controlling the fresh air machine to operate at the maximum rotating speed, and introducing outdoor fresh air into the room after passing through the pre-cooling device.
When detecting and judging that indoor air humidity is less than outdoor air humidity, it is low to explain indoor air humidity, and outdoor air humidity is high, and accessible introduction outdoor air carries out the humidification to indoor to the new fan of control starts with the maximum rotational speed operation, in order to bring in the biggest amount of wind indoor, increase humidification effect, improves the new freshness of indoor air simultaneously. When the indoor air humidity is higher than the outdoor air humidity, the outdoor air humidity is low, and the outdoor fresh air cannot be directly introduced into the room, so that the average humidity of the indoor air is prevented from being reduced. The accessible increases humidification device in the wind channel this moment, and the humidification net among the humidification device is movable, and when needs humidification, it moves to lie in with wind channel air current vertically direction in invading the basin, starts new fan introduction external new trend and passes through the humidification net and get into indoorly, carries out the humidification and improves room air new freshness to the room air. When not needing the humidification, the humidification net moves the direction that is parallel with the wind channel air current and breaks away from the basin, does not start new fan introduction external new trend to the external new trend humidification that gets into the wind channel to increase indoor air new freshness. In addition, when indoor air humidity is less than first default, indoor air is very dry promptly, and the accessible lies in forming indoor wind channel between the indoor air intake of indoor side and the air outlet in new fan, sets up humidification device in indoor wind channel, through indoor wind channel with the air introduction humidification device of indoor side, the realization is to the direct humidification of indoor air to reinforcing humidification effect. When outdoor fresh air is introduced, the temperature of the outdoor fresh air is low in consideration of the indoor refrigeration state, and the indoor refrigeration effect can be influenced by introducing the outdoor fresh air into the room. Thereby set up prefabricated cold charge and put among the new fan of this embodiment and the air conditioner linked system, the control room outer new trend is earlier through prefabricated cold charge and put the temperature reduction processing back, and it is indoor to get into again to improve the new freshness and the humidity of room air when avoiding influencing indoor cooling effect.
Further, on the basis of the second embodiment of the control method of the fresh air machine and air conditioner linkage system according to the present invention, a third embodiment of the present invention is provided, and in the third embodiment, the step of controlling the fresh air machine and the air conditioner to operate in the second operation mode includes:
the operation frequency of the air conditioner refrigeration mode is reduced, and the air inlet volume of the air conditioner and the opening degree of an electronic expansion valve in the air conditioner are increased.
When the indoor temperature is lower than the second preset value and the operation mode of the fresh air fan and air conditioner linkage system is the second operation mode, the temperature of the indoor environment is reduced to meet the requirement of human comfort. Cooling is then no longer the primary requirement of the user, but should be a comfort requirement for humidity. In order to further avoid dehumidification in the refrigeration process, the operation frequency of the air-conditioning refrigeration mode is reduced, namely, the operation frequency is reduced on the basis of the operation frequency of the first operation mode, so that the dehumidification speed is reduced. Meanwhile, in order to ensure cooling, the air inlet volume of the air conditioner and the opening degree of the electromagnetic expansion valve are increased so as to accelerate the circulation flow of indoor air and increase the flow of a refrigerant, so that the refrigeration intensity is increased, and the reduction of the indoor temperature is ensured. In addition, in the second operation mode, the fresh air fan can be started to operate, so that fresh air outside the room can be introduced to increase the freshness of the indoor air. When the humidity of outdoor air is high, outdoor fresh air can be directly introduced for humidification; when the outdoor air humidity is low, the fresh outdoor air can enter the room after being humidified by the humidifying device in the air duct, so that the indoor air humidity is improved.
