Further, according to an embodiment of the present invention, the PMV value may be calculated by setting the indoor temperature, the indoor humidity, and other influencing factors as constants according to seasons and the like; or estimating the influence of the average radiation temperature according to outdoor weather conditions (outdoor temperature and cloudy, sunny, rainy and cloudy), months, outer wall orientation and the like, for example, in the middle and afternoon time periods when the outer wall or the top room is sunned in sunny days in 7 and 8 months in the refrigerating season, and considering the influence of the average radiation temperature. The human body metabolism rate can be obtained by looking up a table according to the activity state of a person, generally speaking, the activity state of the person is mostly standing, sitting, lying and sleeping (falling asleep, light sleeping, sound sleeping, deep sleeping and waking up). For example, the light sensation is smaller than a certain set value to judge that the guest turns off the light to enter the sleep stage, and then the light-off time length is used for judging which stage of the sleep of the guest is. Generally, the body temperature of a person in a sleeping state can change continuously along with the deepening of sleeping time, the body temperature of the person in a sleeping stage is the normal body temperature at ordinary times, but the body temperature can be reduced along with the deepening of sleeping time, and at the moment, the thermal comfort control index can be correspondingly improved; with the automatic adjustment of the biological clock, the body temperature can slowly rise in the early wake-up stage, and the thermal comfort control index can return to the normal level at the moment.
According to the embodiment of the invention, the average radiation temperature refers to the average temperature of the radiation effect of the surrounding surface on the human body, other ornaments in the area where the air conditioner is located are ignored, and the radiation heat exchange between the human body and the environment is assumed to be mainly from the inner surface of the enclosure structure. If the influence of the inner wall is neglected, only the radiation heat exchange quantity of the outer enclosure structure (door, window and wall) is considered, and the average temperature of the inner surface of the outer enclosure structure is the average radiation temperature.
Further, the current PMV value is also related to the wind speed of the air conditioner acting space and the clothing thermal resistance, but the average radiation temperature, the indoor humidity and the human body metabolism rate of the area where the air conditioner is located are main factors influencing the thermal comfort of the human body. The wind speed of the air conditioner active space has little influence on the current PMV value, for example, when clothes/bedding is determined in winter and summer, and the wind speed less than 0.1m/s has little influence on the PMV value.
According to the control method of the air conditioner disclosed by the embodiment of the invention, the operation parameters are adjusted according to the adjustment value corresponding to the current power utilization time period; after the operation parameters are adjusted, acquiring a PMV value in the air conditioner action space; and when the PMV value is positioned in the preset comfortable PMV interval, returning to execute the step of adjusting the operation parameters according to the adjustment value corresponding to the current power utilization time interval so as to realize the operation parameters of the air conditioner in real time and ensure that the PMV value is positioned in the preset comfortable PMV interval, thereby ensuring the comfort of the user.
