Example 2
As shown in fig. 4, the method for controlling a portable outdoor air conditioner according to the embodiment of the present invention specifically includes the following steps:
by pressing the operation switch 16 for a short time, the thermoelectric cooling unit 4 can start cooling. Meanwhile, the human body surface temperature detection unit 5, the temperature detection unit 6 and the humidity detection unit 7 respectively start to detect the human body surface temperature S, the ambient temperature T and the ambient humidity W in real time and feed back to the control device 3.
Firstly, when the control device 3 judges that the environmental temperature T is less than 27 ℃, which means that a user is in a comfortable environment, the input power of the thermoelectric refrigeration unit 4 is controlled, so that the temperature difference between the cold end temperature and the environmental temperature is kept within 5 ℃, and the wind speed of the cross-flow fan 8 is high-grade by default;
meanwhile, when the control device 3 judges that the environmental humidity W is less than or equal to 35%, which means that the user is in a relatively dry environment, the humidifying mode is operated, and the spray humidifying unit 102 is controlled to spray countless water mist particles from the spray holes 15, so that the air humidity in a local range is maintained in a range of 40% -60%, and the comfort level of the human body is further improved. On the contrary, if the control device 3 judges that the environmental humidity W is greater than 35%, it means that the user is in a relatively humid environment, and the humidification mode does not need to be operated;
after a certain time t, when the control device 3 judges that the current human body surface temperature variation delta S is less than 0 (namely S)At present-SInitially, the process is started< 0), the body temperature is reduced, the input power of the thermoelectric cooling unit 4 is further reduced, and the wind speed of the cross flow fan 8 is maintained at a low level. On the contrary, if the control device 3 determines that the current human body surface temperature variation Δ S is greater than or equal to 0 (i.e. S)At present-SInitially, the process is startedNot less than 0), the temperature of the human body is increased or unchanged, the input power of the thermoelectric refrigeration unit 4 is further improved, and the wind speed of the cross flow fan 8 is maintained at a high level;
in the case of the simultaneous operation of the humidification mode, when the control device 3 judges that the ambient humidity in the current local space has exceeded 60%, the humidification mode is stopped. On the contrary, if the control device 3 determines that the ambient humidity in the current local space has not reached 60%, the humidification mode continues to be operated.
Secondly, when the control device 3 judges that the ambient temperature is more than or equal to 27 ℃ and less than or equal to 32 ℃, which means that a user is in a relatively hot environment, the input power of the thermoelectric refrigeration unit 4 is controlled to keep the temperature difference between the cold end temperature and the ambient temperature within 5-15 ℃, and the wind speed of the cross-flow fan 8 is defaulted to be high-grade at the moment;
meanwhile, when the control device 3 judges that the environmental humidity W is less than or equal to 35%, which means that the user is in a relatively dry environment, the humidifying mode is operated, and the spray humidifying unit 102 is controlled to spray countless water mist particles from the spray holes 15, so that the air humidity in a local range is maintained in a range of 40% -60%, and the comfort level of the human body is further improved. On the contrary, if the control device 3 judges that the environmental humidity W is greater than 35%, it means that the user is in a relatively humid environment, and the humidification mode does not need to be operated;
after a certain time t, when the control device 3 judges that the current human body surface temperature variation delta S is less than 0 (namely S)At present-SInitially, the process is started< 0), the body temperature is reduced, the input power of the thermoelectric cooling unit 4 is further reduced, and the wind speed of the cross flow fan 8 is maintained at a low level. On the contrary, if the control device 3 determines that the current human body surface temperature variation Δ S is greater than or equal to 0 (i.e. S)At present-SInitially, the process is startedNot less than 0), the temperature of the human body is increased or unchanged, the input power of the thermoelectric refrigeration unit 4 is further improved, and the wind speed of the cross flow fan 8 is maintained at a high level;
in the case of the simultaneous operation of the humidification mode, when the control device 3 judges that the ambient humidity in the current local space has exceeded 60%, the humidification mode is stopped. On the contrary, if the control device 3 determines that the ambient humidity in the current local space has not reached 60%, the humidification mode continues to be operated.
Thirdly, when the control device 10 judges that the environmental temperature T is more than 32 ℃, which means that the user is in a very hot environment, the input power of the thermoelectric refrigeration unit 14 is controlled, so that the temperature difference between the cold end temperature and the environmental temperature is kept within 15-25 ℃, and the wind speed of the cross flow fan 13 is defaulted to be high-grade at the moment;
meanwhile, when the control device 3 judges that the environmental humidity W is less than or equal to 35%, which means that the user is in a relatively dry environment, the humidifying mode is operated, and the spray humidifying unit 102 is controlled to spray countless water mist particles from the spray holes 15, so that the air humidity in a local range is maintained in a range of 40% -60%, and the comfort level of the human body is further improved. On the contrary, if the control device 3 judges that the environmental humidity W is greater than 35%, it means that the user is in a relatively humid environment, and the humidification mode does not need to be operated;
after a certain time t, when the control device 3 judges that the current human body surface temperature variation delta S is less than 0 (namely S)At present-SInitially, the process is started< 0), the body temperature is reduced, the input power of the thermoelectric cooling unit 4 is further reduced, and the wind speed of the cross flow fan 8 is maintained at a low level. On the contrary, if the control device 3 determines that the current human body surface temperature variation Δ S is greater than or equal to 0 (i.e. S)At present-SInitially, the process is startedNot less than 0), the temperature of the human body is increased or unchanged, the input power of the thermoelectric refrigeration unit 4 is further improved, and the wind speed of the cross flow fan 8 is maintained at a high level;
in the case of the simultaneous operation of the humidification mode, when the control device 3 judges that the ambient humidity in the current local space has exceeded 60%, the humidification mode is stopped. On the contrary, if the control device 3 determines that the ambient humidity in the current local space has not reached 60%, the humidification mode continues to be operated.
Finally, when humidification is not needed, the humidification operation can be stopped only by continuously pressing the two operating switches 16; when the operation switch 16 is continuously pressed for a long time, the power-off operation is performed.
According to the embodiment, the portable outdoor air conditioner and the control method thereof can easily and effectively realize the refrigeration and cooling effects in the local space in any outdoor place without commercial power, and can avoid unnecessary energy waste while meeting the thermal comfort requirement of the human body by automatically adjusting the control function of operation according to the changes of the temperature, the humidity and the body surface temperature of the human body.
