Abstract

PURPOSE:To control temperature with high accuracy, and to improve comfortableness by fitting a plurality of temperature sensors and detecting an indoor temperature by one sensor selected in response to the position of a mode damper or a weighted mean of a plurality of measured data. CONSTITUTION:On the summer period or insolation, etc., blow-off from a lower layer is interrupted when the mode damper 5 is located at a FACE position, air is blown off only from an upper layer, a switch SW is turned OFF, and the temperature of a compartment is detected only by a temperature sensor 12 of the upper layer. On a BI level frequently used in the summer period from the intermediate period, air is blown off from both the upper layer and the lower layer, but it is confirmed that the temperature of the compartment can be detected experimentally only by the temperature sensor 12 of the upper layer. Since hot air must be blown off from the lower layer in the winter period, a FOOT position is selected, and the switch SW is turned ON interlocked with the FOOT position so as to be able to detect the temperature of the compartment even by a sensor 13 in addition to the sensor 12.

Figures 1 and 2 are configuration diagrams of conventional vehicle air conditioners.
The air sucked into the fan 1 and blown is cooled while passing through the evaporator 2. The air mix damper 3 divides the air into the air entering the heater 4 and the air bypassing the heater 4, and the air mix damper/. The mixture is mixed on the downstream side of the bar 3 and blown into the room. The temperature of the air blown into the room is determined by the mixing ratio of the air depending on the position of the air mix damper 3. On the other hand, the air blowing into the room is determined by the position of the mode damper 5, and the FACE position blowing into the upper layer of the room,
Panel 1 has three positions: the FOOT position, which blows air to the lower layer, and the BI level position, which blows air evenly to the upper and lower layers.
The selection is made via the controller 8 and the actuator 7 by a changeover switch 20 located in 0. I cut it. Indoor temperature control. The indoor temperature is detected by a temperature sensor 9 installed indoors so that the temperature reaches the temperature set by a temperature setting device 30 provided inside the panel 10, and after arithmetic processing by the controller 8. This is done by controlling the actuator 6 to operate the air mix damper 3'5. Here, the mode damper 5 is placed in the FA position to blow out cold air from the upper layer in the summer, and is placed in the FO position in order to blow out the warm air from the lower layer in the winter.
He is placed in the OT position/, and in the seasons in between, he is placed in the BT level position. Normally, the temperature sensor 9 is installed at a position that represents the indoor temperature, but since the flow of the blowing air changes greatly depending on the positive/feature of the mode tamper 5, one temperature sensor 9
There was a problem in that it was not always possible to obtain a temperature representative of the room. In addition, depending on the mounting position of the temperature sensor 9, the outside temperature, and the position of the mode damper 5, the temperature detection delay by the sensor may cause extreme haunches in the indoor temperature and outlet temperature. In this case, the gain of the control system must be increased, which increases the noise
1 during no-nching.
.. 11 had the problem of causing uncomfortable phenomena such as cold air blowing from your feet in the winter and warm air blowing against your face in the summer. The present invention has been proposed in view of the above-mentioned points, and an object thereof is to provide a vehicle air conditioner that can perform highly accurate temperature control and improve comfort. The present invention provides a vehicle air conditioner that detects the indoor temperature with a temperature sensor and controls the room temperature so that the interior of the vehicle reaches a set temperature. It is characterized by detecting the indoor temperature by selecting one of the temperature sensors, or by weighted averaging of the measurement data of multiple temperature sensors, and controlling the room temperature, depending on the position of the mode damper. The indoor temperature is detected by selecting one of the multiple temperature sensors installed or by weighted averaging of the measurement data of multiple temperature sensors.
It can reliably capture the indoor temperature and perform highly accurate temperature control. The present invention will be explained below based on examples. In addition. In this embodiment, an example will be described in which two temperature sensors are used to detect the indoor temperature, but the present invention is not limited to this. FIG. 3 shows the configuration of this embodiment, and the configuration other than that shown is the same as the conventional one shown in FIG. 1. 5 is a mode damper due to its positive control. FOOT position, FACE position, and BI level position can be determined. 12 and 13 are temperature sensors that detect the temperature inside the vehicle, and are installed inside the vehicle. The sensor 12 detects the temperature T+ of the upper layer of the room. Sensor 13 measures the temperature T of the lower layer of the room! is connected to the controller 14. FIG. 4 is a circuit diagram of the controller 14, in which a resistor ktc detects a change in resistance of a temperature sensor using voltage. Moreover, when the temperature sensor is a thermistor, it is also useful for improving the linearity of the temperature coefficient. The switch SW is turned on when the FOOT position W/ is selected, and turned off at other times. The resistors R+ and R are selected to have sufficiently large values compared to the above-mentioned resistor LC to the extent that they pose no problem in measurement. During the summer when the outside temperature is high, it is necessary to blow cold air from the upper layer. Therefore, the mode tamper 5 is in the FACE position. In addition, when there is solar radiation even outside of summer,
There are times when the indoor temperature rises and you want to blow out cold air, but even in such cases, it is better to blow out cold air from the upper layer, so your feet will not get cold and you will be more comfortable.
CEpo')'/g/ is sometimes used. In this way, when the mode tamper 5 is at the FAOE position. It is most desirable that the air blowing from the lower layer is blocked and only air blowing comes from the upper layer, and the room temperature is detected by the temperature sensor 12 in the upper layer. In other words, there is a flow of wind around the sensor that detects the temperature. 4 < H 1ra N + (The response r [also gets better. - Horn, Kol), and there is no bay 11 near the polarization sensor 1311, so it is not representative of the current situation. The sensor 13 is harmful because it is unstable and the response of the rm degree detection is slow, causing h/ch/g, and it is better to separate it. From this! F, A blowing out from the two layers
In the CE positive/:in mode, the switch SW is turned off so that only the upper layer temperature sensor 12 detects the room temperature. Furthermore, when the Bl level is often used from mid-season to summer, wind is blown from both the upper and lower layers, but it has been experimentally found that the room temperature can be detected only by the temperature sensor 12 in the upper layer. There is. Furthermore, let's take a look at FOOT positive 7 days, which is often used in the winter. In winter, it is necessary to blow warm air from the lower layer, so the FOOT sensor is the best choice.

In addition to the temperature sensor 12Vζ in the lower layer, the temperature sensor 13 in the lower layer is connected to the F00T positive 7:l7 VC so that the switch SW is turned off so that the room temperature can be detected. The strength of the sensor's action is determined by the fourth
The output value is determined by the ratio of the resistance R+ and the mountain in the figure, and the output value is indoor 11
It is a weighted average of degrees. Note that at this time, it is not the weighted average value of the indoor temperature. The circuit A of the upper layer temperature sensor 12 may be shut off in conjunction with the switch SW, and the room temperature may be detected only by the lower layer temperature sensor 13. As described above, the temperature in the room can be reliably detected by a plurality of installed temperature sensors according to the positive/yeo/position of the mode damper, and the indoor temperature can be controlled with high accuracy.
