摘要:
An air-conditioning device capable of obtaining a suitable blow-out temperature through one passage from the initial period of change even when the air-conditioning operation in which either a first passage or a second passage is closed is changed into an operation condition in which it is opened. A feet mode in which the hot air is blown to the feet of a passenger from a second passage 7, is changed to a bilevel mode in which a first passage 6 that communicates with the upper half body of the passenger is switched from the closed state to the open state. During a predetermined period of time in the initial period following the change, the temperature blown from the first passage 6 is determined based upon a blow-out temperature of the second passage 7 and a desired blow-out temperature TAOV of the first passage 6. At the time of changing the mode, therefore, even when a first temperature sensor 25 is detecting a temperature near a desired blow-out temperature of the first passage 6 before the mode is changed, the air of the present temperature is not blown from the first passage 6 but, instead, a by-pass opening/closing damper 15 is opened, so that the air of a low temperature is blown from the first passage 6.

Temperatures in a Dr side air-conditioning zone and a Pa side air-conditioning zone are controlled highly independently of each other without temperature interference between each zone. A room internal air temperature sensor and a room external air temperature sensor are provided. Dr side and Pa side temperature setters separately set room setpoint temperatures (Tset(Dr), Tset(Pa)) in each zone. First and second target blow-out temperature calculating portions, which include neural network, input the room setpoint temperatures and the temperature data. Then it calculates Dr side and Pa side target blow-out temperatures (TAO(Dr), TAO(Pa)) relative to each air-conditioning zones by using a neural network. Air-mixing doors separately adjusts the temperatures of conditioned air blown out from Dr side air passage and Pa side air passage to be the first and second target blow-out temperatures. Here, the neural network has the learning function, which adjusts its output to be desired data (teacher signal). Therefore, the output at a specific input condition can be adjusted without temperature interference between each zone.

A vehicle air conditioning apparatus in which the larger the air conditioning cooling load in a vehicle compartment, for example, the larger the solar radiation amount, the lower the set temperature or the larger the temperature deviation between set temperature and inner air temperature, the narrower the swing ranges of swing louvers of respective center and side FACE blow outlets are set. Regardless of the swing range of the swing louvers, swing cycles of the swing louvers are set constant, and the narrower the swing ranges of the swing louvers, the slower the swing speeds of the swing louvers are set. Therefore, annoying feeling is reduced, and comfortable feeling for passengers is significantly improved.
摘要:
An air-conditioning apparatus for allowing the temperatures of a first air-conditioning zone and a second air-conditioning zone to quickly approach the respective set temperatures by properly controlling the air flow rate and the ratio of fresh/recirculated air, even when the set temperatures differ from one another. The device includes a controller that determines whether the system is in a transitional period or in a steady state based on the deviation of the compartment temperature detected by the compartment temperature sensor from the first and second set temperatures for the first and second zones. If a determination is made that the system is in a transitional period, the controller acts to determine the flow rates of air being supplied to respective blowers as well as making the determination concerning the guidance ratio of the fresh to recirculated air.
摘要:
An air conditioning system for an automobile having an evaporator, in a refrigerating circuit, and a heater core which is located downstream from the evaporator in a duct having an inlet for introduction of air and an outlet for discharging the air into a cabin, and an air mix damper for controlling the ratio of the amount of air into the heater core and the amount of air by-passing the heater core. The degree of the opening of the air mix damper is controlled in accordance with the cooling capacity at the evaporator sensed by an after-evaporator temperature sensor so that a target value of the temperature of the air discharged into the cabin is obtained. A correction of the degree of opening of the air mix damper is done by estimating an actual temperature at the after-evaporator sensor during a transient state of the system between the ON and OFF conditions of a compressor, so that a desired setting of the air conditioning state is maintained. The target air temperature is not corrected if it is determined that the system is in a heating mode.

A manipulation display area and an operation state display area are disposed in a display. The manipulation display area is divided into a constant area and a variable area. The constant area includes manipulation items to be most frequently selected by a user, while the variable area includes manipulation items to be altered according to use condition. Thereby the user can easily reach a necessary manipulation item among a lot of the manipulation items.
摘要:
According to the present invention, an air conditioner for a vehicle cancels the thermal interference with a rear-seat side from a front-seat side even when the difference in target temperature between the front-seat side and the rear-seat side is equal to a predetermined value or more. When the difference a set temperature on the front-seat side and a set temperature on the rear-seat side is equal to .+-.3 (.degree.C.) or more, a ratio of the outside air sucked into a front-seat air conditioner unit is decreased according to an increase in the difference between the set temperatures. In this way, since the amount of air which is blown out from the front-seat air conditioner unit and further flows into the rear-seat side is decreased, it is possible to cancel the thermal interference from the front-seat side, by means of air blown out from a rear-seat air conditioner unit.
