All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a flowchart of an embodiment of a control method of an air treatment device of the present invention, and as shown in fig. 1, the control method of the air treatment device of the present embodiment may specifically include the following steps:
100. if the air treatment equipment operates in a humidity adjusting mode, determining the humidity adjusting type of the air treatment equipment; if the humidity adjustment type is dehumidification, executing step 101; if the humidity adjustment type is humidification, executing step 102;
in this embodiment, when the moisture in the environment is more or less, the user may be uncomfortable, and therefore, the air treatment device needs to perform humidity adjustment on the environment, and at this time, the air device operates in the humidity adjustment mode. When the air processing apparatus performs dehumidification, the air processing apparatus humidity adjustment type may be determined to be dehumidification, and when the air processing apparatus performs humidification, the air processing apparatus humidity adjustment type may be determined to be humidification.
101. According to the obtained current indoor environment humidity and the current indoor environment temperature, determining dehumidification parameters of at least one refrigerant circulation mechanism for dehumidification and heating parameters of at least one refrigerant circulation mechanism for heating corresponding to the refrigerant circulation mechanism for dehumidification along the airflow direction;
in order to accurately adjust the temperature of the air flow blown out by the air processing equipment and reduce the energy consumption in the temperature adjustment process, in this embodiment, the air processing equipment includes at least two refrigerant circulation mechanisms, and the temperature of the air flow blown out by the air processing equipment can be adjusted by the refrigerant circulation mechanisms under different humidity adjustment types.
Specifically, if the humidity control type is dehumidification, the air processing device needs to cool the room to lower the room temperature, so as to reach the dew point of the high-humidity air and remove moisture, and at this time, the temperature of the air flow blown into the room is lowered, and in order not to affect the user's feeling, the temperature of the dehumidified air flow needs to be raised to ensure that the temperature of the air flow blown out by the air processing device is within the temperature range set by the user while dehumidification is performed.
In this embodiment, the humidity sensor may be used to collect the current indoor environment humidity, and the thermal bulb may be used to collect the current indoor environment temperature, so that after the current indoor environment humidity and the current indoor environment temperature are obtained, the dehumidification parameters of the at least one refrigerant circulation mechanism for dehumidification along the airflow direction, such as the evaporation temperature and the dehumidification air volume, may be determined according to the obtained current indoor environment humidity and the current indoor environment temperature. After the dehumidification parameter of the at least one refrigerant circulation mechanism for dehumidification is determined, the temperature of the dehumidified airflow by the at least one refrigerant circulation mechanism for dehumidification can be further determined, and then the heating parameter of the at least one refrigerant circulation mechanism for heating corresponding to the refrigerant circulation mechanism for dehumidification can be further determined, so that the refrigerant circulation mechanism for heating heats the airflow processed by the refrigerant circulation mechanism for dehumidification, and the temperature of the airflow blown out by the air processing equipment finally reaches the temperature set by the user. Wherein, the refrigerant circulating mechanism for heating is positioned at the downstream position of the refrigerant circulating mechanism for dehumidification.
For example, the air equipment includes 2 refrigerant circulation mechanisms to describe the technical scheme of the invention. Fig. 2 is a schematic view of a topology of the air treatment device of the present invention, and as shown in fig. 2, the air treatment device of the present embodiment includes: a first refrigerant circulating mechanism A and a second refrigerant circulating mechanism B. The first refrigerant circulating mechanism A comprises a first compressor motor hot belt 1, a first variable frequency compressor 2, a first four-way valve 3, an air duct 4, a first outdoor unit heat exchanger 5, a first throttling device 6, a first fan assembly 8 and the left side of an indoor unit heat exchanger 9. The second refrigerant circulation mechanism B includes a right side of the indoor unit heat exchanger 9, a second throttling device 11, a second outdoor unit heat exchanger 12, a second fan assembly 13, a second four-way valve 14, a second inverter compressor 15, and a second compressor motor hot belt 16.
If the humidity adjustment type is dehumidification, the first refrigerant circulation mechanism a performs refrigeration, at this time, a low-temperature low-pressure gaseous refrigerant is compressed into a high-temperature high-pressure superheated gaseous refrigerant by the first inverter compressor 2, the refrigerant in this state is cooled into a medium-temperature high-pressure liquid refrigerant by the first outdoor heat exchanger 5, the refrigerant in this state is throttled into a low-temperature low-pressure refrigerant by the first throttling device, and returns to the first inverter compressor 2 after exchanging heat with indoor air by one side of the indoor heat exchanger 9. In the throttling process, a low-flow high-pressure ratio mode is adopted, so that the evaporation temperature is lower than the dew point temperature of high-humidity air, and the moisture is separated from the air to be dehumidified. The second refrigerant circulation mechanism B carries out a heating mode, low-temperature and low-pressure gaseous refrigerant is compressed into high-temperature and high-pressure superheated gaseous refrigerant through the second inverter compressor 15, the refrigerant in the state is subjected to heat exchange through the right side of the indoor unit heat exchanger 9 to form medium-temperature and high-pressure liquid refrigerant, the medium-temperature and high-pressure liquid refrigerant and the air dehumidified by the first refrigerant circulation mechanism A carry out heat exchange to improve the temperature of the dehumidified air, the air enters the first throttling device 6 to be throttled into the low-temperature and low-pressure refrigerant, and the low-temperature and low-pressure gaseous refrigerant is changed into the low-. Thus, circulation is completed, and the effect of controlling the temperature of the dehumidified air is achieved.
In this embodiment, the current indoor environment temperature and the current indoor environment relative humidity may be collected according to the following manner. Specifically, a preset time may be set, and the preset time is used as a detection period to detect the current indoor environment relative humidity of a plurality of detection periods, where the first preset time may be preferably 10min, and the detection of the current indoor environment relative humidity of different detection periods is performed 1min before the detection period is performed as a data acquisition time, during the acquisition period, the first inverter compressor 2, the first fan assembly 8, and the second refrigerant circulation mechanism B do not operate, and when the next detection period is started after every 10min, an average value of the temperature and the humidity of the last 1min of the previous detection period is a current indoor environment relative humidity value of the next detection period. In this embodiment, divide into a plurality of cycles with the detection of current indoor environment relative humidity, but the change of current indoor environment relative humidity among the real-time supervision dehumidification process, then, to the current indoor environment relative humidity of certain cycle, adjust evaporating temperature, dehumidification amount of wind in real time, and then improve the dehumidification control accuracy and the dehumidification comfort level of air conditioner.
It should be noted that, when the air processing equipment dehumidifies, the two refrigerant circulation mechanisms respectively refrigerate and heat, and no matter the indoor heat exchanger or the outdoor heat exchanger, the inlet air can be cooled by the left side (evaporator) of the indoor heat exchanger. When the low-temperature inlet air flows through the right side (condenser) of the indoor heat exchanger, the temperature of the refrigerant is reduced, the condensation temperature is reduced, and the condensation pressure is reduced. The power consumption of the first frequency conversion compressor is reduced, the refrigeration coefficient is improved, and the operation economy is improved, so that the aim of saving energy is fulfilled.
102. And determining the cooling parameters of at least one cooling refrigerant circulating mechanism for cooling along the airflow direction according to the current indoor environment humidity and the current indoor environment temperature.
In a specific implementation process, if the humidity adjustment type is humidification, the air processing device needs to heat water to convert the water into water vapor, at this time, the temperature of the water vapor is high, and if the water vapor is directly blown out, although the humidification effect can be achieved, the indoor temperature can be relatively raised and exceeds the temperature set by the user, so that in order not to affect the feeling of the user, the temperature of the airflow after humidification needs to be lowered to ensure that the temperature of the airflow blown out by the air processing device is within the temperature range set by the user while dehumidification is performed.
Specifically, according to the current indoor environment humidity and the current indoor environment temperature, the temperature reduction parameters of the at least one temperature reduction refrigerant circulation mechanism along the airflow direction are determined, so that the at least one temperature reduction refrigerant circulation mechanism can reduce the temperature of the humidified airflow.
As shown in fig. 2, in this embodiment, the humidified air flow may be cooled by the first refrigerant circulation mechanism a, the second refrigerant circulation mechanism B is not operated, the humidified air flow may also be cooled by the second refrigerant circulation mechanism B, the first refrigerant circulation mechanism a is not operated, or the humidified air flow may also be cooled by two refrigerant circulation mechanisms, which is not specifically limited in this embodiment.
The working principle when dehumidification is carried out is as follows: the low-temperature low-pressure gas refrigerant is compressed into the high-temperature high-pressure superheated gas refrigerant through the first inverter compressor 2, the refrigerant in the state is cooled into the medium-temperature high-pressure liquid refrigerant through the first outdoor unit heat exchanger 5, the refrigerant in the state is throttled into the low-temperature low-pressure refrigerant through the first throttling device, and the low-temperature low-pressure refrigerant exchanges heat with indoor air humidified by the humidifier through the left side of the first heat exchanger and then returns to the first inverter compressor 2. Therefore, the temperature of the air which rises after humidification is reduced, the temperature of the air before humidification is maintained, and the effect of temperature control and humidification is achieved.
On one hand, in the control method of the air processing equipment of the embodiment, when the humidity adjustment type is dehumidification, according to the acquired current indoor environment humidity and current indoor environment temperature, a dehumidification parameter of at least one refrigerant circulation mechanism for dehumidification and a heating parameter of at least one refrigerant circulation mechanism for heating, which correspond to the refrigerant circulation mechanism for dehumidification, are determined in the airflow direction, so that the refrigerant circulation mechanism for heating heats the airflow processed by the refrigerant circulation mechanism for dehumidification, and constant temperature dehumidification is realized; on the other hand, if the humidity adjustment type is humidification, according to the current indoor environment humidity and the current indoor environment temperature, the temperature reduction parameters of the at least one cooling refrigerant circulation mechanism along the airflow direction are determined, so that the at least one cooling refrigerant circulation mechanism can reduce the temperature of the humidified airflow, and constant-temperature humidification is achieved. By adopting the technical scheme of the invention, the practicability of the air treatment equipment can be improved.
Further, in the above embodiment, in order to ensure that the indoor humidity always meets the requirement of the user, in this embodiment, after the current indoor environment temperature is obtained, the humidity adjustment type corresponding to the current indoor environment humidity can be determined according to the association relationship between the preset environment humidity and the humidity adjustment type, so that the current indoor environment humidity can be monitored in real time, and the environment humidity can be cyclically adjusted in the dehumidification process and the humidification process.
In practical application, if humidity adjustment is not needed, the air processing equipment can also operate in a temperature adjustment mode, at the moment, the required temperature of a user can be obtained, the temperature adjustment parameter of at least one refrigerant circulation mechanism for temperature adjustment is determined according to the required temperature of the user, and the at least one refrigerant circulation mechanism for temperature adjustment is controlled according to the determined temperature adjustment parameter.
For example, the air processing apparatus may operate in a normal cooling mode, at this time, a low-temperature low-pressure gaseous refrigerant is compressed into a high-temperature high-pressure superheated gaseous refrigerant by the first inverter compressor of the first refrigerant circulation mechanism, the refrigerant in this state is cooled by the first outdoor unit heat exchanger to a medium-temperature high-pressure liquid refrigerant, the refrigerant in this state is throttled by the first throttling device to a low-temperature low-pressure refrigerant, and the refrigerant returns to the first inverter compressor after exchanging heat with indoor air through the left side of the indoor heat exchanger. Therefore, the temperature of the indoor air is reduced, and the refrigerating effect is achieved. In addition, the refrigeration process can also be completed by the second refrigerant circulation mechanism, and the realization principle is the same as that of the first refrigerant circulation mechanism, and the details are not repeated here.
Air handling equipment can operate and strengthen the refrigeration mode, this moment, by two refrigerant circulation mechanism accomplish simultaneously refrigeration process can, indoor air temperature reduction range will promote greatly like this, refrigerated effect is more obvious.
The air processing equipment can operate in a common heating mode, at the moment, low-temperature low-pressure gaseous refrigerant is compressed into high-temperature high-pressure superheated gaseous refrigerant through a first variable frequency compressor of a first refrigerant circulating mechanism, the refrigerant in the state is subjected to heat exchange through the left side of an indoor unit heat exchanger to form intermediate-temperature high-pressure liquid refrigerant, the intermediate-temperature high-pressure liquid refrigerant exchanges heat with indoor air to improve the temperature of the indoor air, then the intermediate-temperature high-pressure liquid refrigerant enters a first throttling device to be throttled into low-temperature low-pressure refrigerant, and the low-temperature low-pressure gaseous refrigerant is changed. Thus, the circulation is completed, and the heating effect is achieved. In addition, the heating process can also be completed by the second refrigerant circulating mechanism, and the realization principle is the same as that of the first refrigerant circulating mechanism, and is not described again here.
Air handling equipment can operate under strengthening the mode of heating, this moment, by two refrigerant circulation mechanisms accomplish simultaneously heat process can, accomplish the circulation like this, indoor air increases the temperature range and will promote greatly, and the effect of heating is more obvious.
In a specific implementation process, in order to ensure that the service life of each refrigerant circulation mechanism is on a horizontal line, in this embodiment, if the number of the refrigerant circulation mechanisms for temperature adjustment is smaller than the number of all the refrigerant circulation mechanisms, the refrigerant circulation mechanisms for temperature adjustment and the refrigerant circulation mechanisms which are not started are switched cyclically according to a preset rule.
Specifically, after the operation duration of each refrigerant circulation mechanism reaches the preset duration, the refrigerant circulation mechanisms which are not started can be started, and the refrigerant circulation mechanisms for temperature adjustment corresponding to the number of the refrigerant circulation mechanisms which are not started are closed. If the number of the refrigerant circulating mechanisms which are not started is not equal to that of the refrigerant circulating mechanisms for temperature adjustment, one refrigerant circulating mechanism for temperature adjustment can be randomly closed, and other refrigerant circulating mechanisms for temperature adjustment are closed according to the adjacent principle, so that the service time of all the refrigerant circulating mechanisms approaches the same as the service times of the air treatment equipment are increased under the principle of probability, the historical service time of each refrigerant circulating mechanism does not need to be counted, and the operation process is reduced. Similarly, the number of the refrigerant circulating mechanisms which are not started can be started at random, so that the service time of all the refrigerant circulating mechanisms is approximately the same.
