In the process of cooling, the indoor heat exchanger 112 serves as an evaporator, the first power device 111 can introduce indoor air into the heat exchange device body for heat exchange, and after the indoor heat exchanger 112 (evaporator) absorbs heat, the first power device 111 guides out the cooled air.
Similarly, in the heating process, the indoor heat exchanger 112 serves as a condenser, the first power unit 111 can introduce indoor air into the heat exchange device body for heat exchange, and after the indoor heat exchanger 112 (condenser) releases heat, the first power unit 111 can lead out the heated air.
Wherein the temperature parameter is positively correlated with the power of the first power plant 111; the smoke parameter is positively correlated with the power of the second power means. The first power device 111 is used for adjusting the blowing gear of the air conditioner, and the second power device is used for adjusting the gear for absorbing steam oil smoke.
For example, when a diner opens a barbecue pan or other equipment, smoke and temperature are low, a smoke absorption gear is automatically opened and set to 1 gear, and suction is 12m3Min; when the temperature detected by the temperature sensor exceeds 60 ℃, the gear for absorbing hot steam is automatically set to 2, and the suction force is 14m3Min; when the temperature detected by the temperature sensor exceeds 90 ℃, the gear for absorbing hot steam is automatically set to 3 gears, and the suction force is 16m3At this time, the wind outlet speed of the air conditioner is increased by 1 gear, for example, the wind speed is changed into a wind speed damper before, and then the wind speed is changed into a high wind speed damper; when the temperature detected by the temperature sensor exceeds 120 ℃, the gear for absorbing hot steam is automatically set to 4 gears, and the suction force is 18m3Min, increasing the wind outlet speed gear of the air conditioner by 1 gear at the moment, for example, the wind speed gear is a wind stroke wind shield before, and the wind speed gear is adjusted to a high wind shield at the moment; when the temperature detected by the temperature sensor exceeds 150 ℃, the gear for absorbing hot steam is automatically set to 5 gears, and the suction force is 20m3And/min, increasing the wind outlet speed gear of the air conditioner by 1 gear at the moment, for example, the wind outlet speed gear is a wind stroke windshield before, and is adjusted to a high wind windshield at the moment.
When the user closed equipment such as oven, the function normal operating of air conditioner this moment or set for alone according to the user and shut down, the function that absorbs smog continues to keep the start-up operation to move according to 5 shelves, detect the temperature and be less than 50 degrees until temperature sensor, and smoke sensor closes this function when detecting no smog.
According to the control method of the air conditioning system in the catering area, provided by the embodiment of the invention, the smoke parameter and the temperature parameter are obtained through the smoke sensor and the temperature sensor, and the first power device in the heat exchange device body and the second power device in the oil fume device body are controlled on the basis, so that the temperature can be adjusted by starting the air conditioning mechanism when a user has a meal, meanwhile, smoke and hot steam are prevented from influencing the dining environment of the user, and the system can correspondingly adjust the heat exchange device and the oil fume device in the air conditioning mechanism through the smoke parameter and the temperature parameter, so that the intelligent home effect is realized, and the user experience is effectively improved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
