Abstract

PURPOSE:To enable an automatic changing of a set room temperature to be performed by a method wherein a control part is provided for judging in which mode cooling or heating operation is performed from a blown air temperature sensed by a blown air temperature sensor, adjusting blown quantities of hot air and cold air and automatically adjusting a room temperature to a set temperature. CONSTITUTION:A blown air temperature sensed by a blown air temperature sensor 7 is compared with a temperature set in a blown air setting unit 23 by a comparator 11. When the blown air temperature is more than a set temperature of the blown air temperature setting unit 23, it is judged that a heating operation is carried out: if it is less than the set temperature, it is judged that a cooling operation is performed. In case a changing-over switch 22 is changed over to an automatic temperature setting mode, an input of either one of a heating temperature setting unit 20a or a cooling temperature setting unit 20b is inputted by a selector circuit. In case of a heating operation in which the temperature is more than the set temperature, an output of the heating temperature setting unit 20a is inputted to the comparator 12. In turn, in case the temperature is less than the set temperature during its cooling action, the output of the cooling temperature setting unit 20b is inputted and a room temperature is automatically adjusted at the set temperature.

It determines whether the four units are operating in cold or hot mode, and controls the above damper based on the room temperature detected by the room temperature sensor and the air volume detected by the landscape sensor to control the amount of hot air and cold air blown out. It is equipped with a control unit that automatically adjusts the room temperature to the winter and summer set temperature of the temperature setting device, and the air conditioner can be operated in either cooling or heating mode based on the air temperature detected by the air temperature sensor. This system is designed to automatically change room temperature settings in winter and summer by determining whether the room temperature is being adjusted.

(Example) An embodiment of the present invention is shown in FIGS. 1 to 3.

The air-conditioning air volume control device 1 of this embodiment is installed on the ceiling, and a blower duct (not shown) is connected to the blower opening 2, through which hot or cold air is sent from the air conditioner. It is being The inside of the air conditioner 1 is as follows:
There is a blowing chamber A in which hot or cold air blown from an air conditioner is blown into and blows out from the air outlet 3 on the bottom surface, and a ventilation chamber B in which indoor air is sucked in from the suction port 4 on the bottom surface and exhausted to ventilate the room. It is a provision. A damper 5 is provided in the suction chamber A to adjust the amount of air blown from the air outlet 2. The amount of air blown by the Goomba 5 is adjusted by a motor 6 as shown by the arrow in the middle. By moving it later and varying the opening area of the air outlet 5, the QrR section is performed. In this embodiment, a blowing temperature sensor 7 that detects the temperature of the air blown through the blowing duct is provided in the blowing port 2, and a wind speed sensor serving as an air volume sensor that detects the amount of air blown out from the blowing port 3. 8 are arranged. In addition, in ventilation room B,

Then, from the air temperature detected by the air temperature sensor 7, it is determined whether the air conditioner is being operated in cooling or heating mode f1.
Based on the room temperature detected by the room temperature sensor 9 and the air volume detected by the wind speed sensor 8, the damper 5 is controlled to reduce the amount of hot air and cold air blown from the outlet 3 to rJ4! ! L
, is equipped with a control unit 10 that automatically adjusts the room temperature to a set temperature for each winter and summer, and the set temperature is set by a temperature setting unit 20 of the control unit 10 for each cooling time and heating time. That is, the temperature setting unit 20 includes a heating temperature setting device 20a to which a heating temperature is set and a cooling temperature setting device 20b to which a cooling temperature is set.For example, the heating temperature setting device 20a has one
8°, and the cooling temperature setting device 20b is set to 28°.

In addition, in this embodiment, a manual temperature setting device 21 is provided separately from the temperature setting section 20 so that the room temperature can be adjusted manually, and it is possible to switch between automatic temperature setting mode and manual temperature setting mode. Hands to do! An IJ/automatic changeover switch 22 is provided. Also, a blower temperature setting device 2 sets a reference temperature for determining whether the air conditioner is in cooling operation or heating operation based on the temperature of the air blown from the blower duct detected by the blower temperature sensor 7.
3 is also a preparation.

Further, the detailed configuration of the control section 10 will be explained with reference to the chart 70 showing the operation of FIG. 2.

The air temperature detected by the air temperature sensor 7 is compared with the temperature set in the air temperature setting device 23 by the comparator 11, and when the air temperature is equal to or higher than the temperature set in the air temperature setting device 23, heating is performed. In addition to identifying that
When the temperature is below the set temperature, it is determined that cooling is being performed. If the automatic/manual selector switch 22 is currently set to automatic temperature setting mode,

, which output of the cooling temperature setting device 20b is manually selected to be input to the comparator 120. For example, during heating when the air blowing temperature is higher than the set temperature of the air blowing temperature setting device 23, the output of the comparator 11 is Since the input connected to the automatic/manual selector switch 22 is also at a high level, the ANDDATE G1 output is at a high level, and the ANDDATE G1 output is at a high level.

Therefore, the output of the heating temperature setting device 20o is input to the comparator 12. On the other hand, when the air temperature is lower than the set temperature of the air temperature setting device 23 during cooling, the output of the comparator 11 is low level, and the output of ANDATE G2 is high level.

The output becomes low level, the analog switch SW2 is closed, and the analog switch SW) is opened. Therefore, the output of the cooling temperature setting device 20b is input to the comparator 12. In this way, in this embodiment, the temperature of the air blown from the ventilation duct is detected, and it is automatically determined whether it is winter or seasonal, and based on this determination result, the set temperature for winter and each season is determined. Automatically adjusts the room temperature. This eliminates the need to use a room thermostat to set the temperature each season as in the past, and it is especially time-consuming to change settings, unlike when a room thermostat is installed in an air conditioning air volume control device installed on the ceiling.

This selection circuit uses analog switches sw, , sw5 and inverter I3 to select vI! has been completed. If the air conditioner is currently being cooled and the room temperature detected by the room temperature sensor 9 is lower than the set temperature of the cooling temperature setting device 2011, the output of the comparator 12 becomes low level. At this time, since the output of the comparator 11 is also at a low level, the output of the exclusive off circuit G is also at a low level. Therefore, analog switch SW,
is closed and the output of the minimum air volume setting device 14 is input to the determination section 15.

The determination unit 15 compares the outputs of the wind speed sensors 8 and controls the motor 6 by controlling the motor drive circuit 16 so that the amount of air blown out from the air outlet 3 is minimized, thereby blowing the Goomba 5. It is moved to the mouth 2 side to reduce the amount of air blown out from the air outlet 3. Therefore, the amount of cold air blown into the room is reduced, and the excessively cold room temperature is raised. Further, during cooling, if the room temperature is higher than the set temperature of the cooling temperature setting device 201), the output of the comparator 12 becomes high level, the output of the exclusive off circuit G becomes high level, and the analog switch SW, is closed and the output of the maximum air quality setting device 13 is manually inputted to the discriminator 15, and the output of the discriminator 15 moves Goomba 5 away from the air outlet 2 to increase the air volume, and the amount of cold air blown from the air outlet 3 is increased. This cools down the room where the temperature has risen. If the room temperature is higher than the temperature set on the heating temperature setting device 20a during heating, the room temperature is overheated, so lower the room temperature by reducing the air volume to the minimum air volume in the same manner as in the case of cooling described above. On the other hand, when the room temperature is low, the air volume is set to the maximum level to adjust the room temperature.In the above explanation, the temperature was automatically set using the output of the temperature setting unit 20, but the manual temperature setting unit 21 When setting the room temperature to a desired temperature using the output, the operation is almost the same as that described above.

[Effects of the Invention] As described above, the present invention includes an air temperature sensor that detects the temperature of air blown through the air duct, an air volume sensor that detects the amount of air blown from the outlet, and a room temperature sensor that detects the room temperature. The sensor, a temperature setting unit that sets the room temperature during cooling and heating, and the air temperature detected by the air temperature sensor determine whether the air conditioner is being operated in cooling or heating mode, and set the room temperature. Based on the room temperature detected by the sensor and the wind speed detected by the wind sensor, the damper is controlled to adjust the amount of hot air and cold air. and a control unit that automatically adjusts the temperature to the set temperature for each v′rL, so the control unit determines whether the air conditioner is being operated in cooling or heating mode based on the air temperature detected by the air temperature sensor. It is possible to automatically change the room temperature settings in winter and summer, which eliminates the need to set the temperature with a room thermometer every season, especially when the room thermometer is installed on the ceiling. This has the advantage that it does not take much time to change the settings, which is the case with the air volume adjustment device.
