Abstract

PURPOSE:To contrive to improve the habitability by a method wherein an air- conditioning device is controlled considering not only the room temperature as an air temperature but also a radiant heat. CONSTITUTION:When there is no radiation, only a room temperature sensor 7 operates and when there is radiation, a radiation sensor 8 operates besides the room temperature sensor 7 and outputs to a controller 6. In the controller 6, the opening of a valve 5 is controlled to control the blow-off temperature from a flow outlet 4 so as the temperature in the room 1 becomes adequate one.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioning control method used to improve the livability inside a house or building.

[Conventional technology]

The room is cooled or heated by an air conditioner to maintain an appropriate temperature, but the operation of the air conditioner is controlled by a room temperature sensor installed in the room.

That is, the room temperature sensor detects the air temperature using a bimetal, diaphragm, or other mechanism, and uses this temperature measurement to influence the controller of the air conditioner to maintain an appropriate room temperature.

[Problem that the invention seeks to solve]

By the way, the reason why people feel heat when they are indoors is that in addition to receiving the temperature of the surrounding air through heat transfer, for example, if you are near a window, you receive heat from the sun directly as radiant heat. Sometimes.

This radiant heat is generated not only by sunlight but also by radiation from the outdoors and radiation due to temperature rise on the indoor side of the exterior wall, but during the cooling period, even if the room temperature (air temperature) is at the set room temperature (for example, 26°C). This radiant heat can make you feel hot, and the discomfort cannot be completely eliminated.

SUMMARY OF THE INVENTION An object of the present invention is to provide an indoor air conditioning control method that eliminates the disadvantages of the conventional example and allows more appropriate temperature control.

[Means for solving problems]

In order to achieve the above object, the control method of the present invention provides a radiation sensor that detects radiant heat in addition to a room temperature sensor that detects air temperature, and adds control by the radiation sensor to the control of the air conditioner by the room temperature sensor. The gist is to do so.

[Effect]

According to the present invention, it is possible to control the air conditioner by taking into account not only room temperature as the air temperature but also radiant heat, and as a result, it is possible to further improve livability.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is an explanatory diagram showing an embodiment of the control method of the present invention, in which 1 indicates an interior of a building and 2 indicates a window glass.

An air conditioner 3 is installed in the room 1, and its air outlet 4 is formed in the ceiling. There are various types of air conditioners 3, such as those for cooling only and those for both cooling and heating.For example, there are those that use hot water and cold water, and the circulation pipe has an air outlet from the outlet 4. A regulating valve 5 is provided to control the air temperature.

Furthermore, 6 in the figure is a controller that opens and closes this adjustment valve 5, and has a temperature setting value that should keep the room 1 at an appropriate temperature.
It has a function of obtaining a measured value from an external temperature sensor and controlling the valve 5 so that the measured value of the temperature sensor matches the set value.

On the other hand, a room temperature sensor 7 operated by thermal expansion is provided in the room 1, and a radiation sensor 8 is provided in the room 1 or outdoors, and measurement output signals from the room temperature sensor 7 and the radiation sensor 8 are introduced into the controller 6.

This radiation sensor 8 measures both the temperature that is not exposed to radiation and the temperature that is exposed to radiation, and outputs the difference.An example of this is shown in Figure 2.The temperature that is not exposed to radiation can be measured. As shown in (a), the sensor T1 is surrounded by a perforated and ventilated cover plate 9, and the radiated temperature is measured by providing a heat collecting plate 1o and bringing the sensor T2 into contact with this heat collecting plate 10. establish. In addition, sensor T1. As shown in FIG. 3, T2 itself has a PTC thermistor (positive temperature characteristic thermistor) and a temperature resistor P1. made of Pt, Ni, etc.
In combination with P2, bridge connection is used to extract a voltage proportional to the temperature difference, or by using a thermocouple using 1iJ (Cu) or Constantun as shown in Figure 4, a voltage proportional to the temperature difference can be detected. There are many possible methods.

The relationship between the room temperature sensor 7 and the radiation sensor 8 is such that they are installed as independent devices, and the output signals from each sensor 7 and 8 are individually introduced into the controller 6 and adjusted within the controller 6. and
It is both possible to configure both sensors 7.8 as one device and to introduce the regulated output signal to the controller 6.

Next, the operation and function will be explained. If there is no radiation, only the room temperature sensor 7 is activated, and if there is radiation, the radiation sensor 8 is activated in addition to the room temperature sensor 7, and output is output to the controller 6. The controller 6 controls the opening degree of the valve 5 to adjust the temperature of the air blown from the outlet 4 so that the temperature in the room 1 becomes an appropriate temperature.

〔Effect of the invention〕

As described above, the indoor air conditioning control system of the present invention takes into account the presence of radiant heat generated by sunlight in addition to the indoor air temperature. It is possible to prevent the user from feeling uncomfortable due to the heat, and it is possible to more appropriately control the indoor temperature and improve the livability.
