Definitions

  • This invention relates to a system for automatically controlling the interior temperature of e.g. a house, especially during summertime, to an optimum level.
  • Air-conditioners and ceiling fans are used to keep the interior temperature during summertime to a comfortable level. These devices were heretofore controlled by manually operating switches attached to these devices to a temperature and a rotational speed which the operator feels are most suitable. But it is difficult to operate these devices taking into consideration the interaction between these devices. It is also extremely troublesome to finely adjust these devices according to temperatures inside and outside the room that change with time. Electric energy is also wasted.
  • An object of the invention is to provide a control system which can automatically control air-conditioners and other devices according to the temperatures inside and outside the room, thereby keeping the interior temperature to a comfortable level.
  • the present invention provides an interior temperature control system comprising at least a top light, a ceiling fan and an air-conditioner that are all installed in or on a house, upper and lower temperature detecting means for detecting the temperatures of upper and lower portions of a room respectively, an outside air temperature detecting means, and a controller for selectively opening and closing the top light, selectively rotating the ceiling fan in one or the opposite direction, and selectively activating and deactivating the air-conditioner, according to signals from the detecting means.
  • the controller may include means for comparing the temperatures of upper and lower portions of the room based on signals from the upper and lower temperature detecting means, means for comparing an interior temperature which is one or the average of the temperatures of the upper and lower portions of the room with the outside air temperature detected by the outside air temperature detecting means, means for comparing the interior temperature with a predetermined temperature, and means for selectively opening and closing the top light, selectively rotating the ceiling fan in one and an opposite direction, and selectively activating and deactivating the air-conditioner, based on the results of comparison.
  • FIG. 1 is a schematic view showing devices used in the interior temperature control system
  • FIG. 2 is a schematic view showing different such devices
  • FIG. 3 is a block diagram showing a method of controlling the interior temperature control system
  • FIG. 4 is a flowchart showing processing steps of the interior temperature control system.
  • FIG. 5 is a flowchart showing processing steps of the interior temperature control system.
  • FIGS. 1 and 2 are schematic views of devices installed in or on a house.
  • a top light T 1 is mounted on a ceiling 2 of the house 1 . It can be opened and closed in response to a signal applied to a control unit C 1 .
  • the top light T 1 is provided with a rain sensor which applies a signal to the control unit C 1 when it is raining to allow the control unit to close the top light T 1 .
  • the top light may have a blind too.
  • a ceiling fan T 2 is fixed to the interior surface of the ceiling 2 near the top light T 1 .
  • the ceiling fan can be rotated at a suitable speed in either direction in response to a signal applied to a control unit C 2 to produce an upward or downward air current in the room 3 .
  • an air-conditioner T 3 is installed, which is activated for cooling and deactivated by a control unit C 3 .
  • a temperature sensor D 1 is provided at a suitable upper portion of the room 3 .
  • another temperature sensor D 2 is provided at a suitable lower portion of the room 3 .
  • Still another temperature sensor D 3 is provided at a suitable location outside the room 3 , such as under the floor.
  • an air-intake fan T 4 and an exhaust fan T 5 may be further provided for more efficient ventilation of the room.
  • an electric awning T 6 may be provided e.g. over the terrace to control the incoming sunlight.
  • signals from the temperature sensors D 1 , D 2 and D 3 are transmitted through wires or by radio to the controller C, which performs calculation based on these signals and outputs control signals to the control units C 1 , C 2 and C 3 to activate the top light T 1 , ceiling fan T 2 and air-conditioner T 3 , thereby keeping the temperature in the room to an optimum level.
  • the controller C performs calculation based on these signals and outputs control signals to the control units C 1 , C 2 and C 3 to activate the top light T 1 , ceiling fan T 2 and air-conditioner T 3 , thereby keeping the temperature in the room to an optimum level.
  • the detector means Dn are not limited to temperature sensors but may be hygrometers or optical sensors.
  • steps S 10 , S 11 and S 12 the temperature difference X between the upper and lower portions of the room, the difference Y between the temperatures inside and outside of the room, and the difference Z between the temperature inside the room and a predetermined temperature are calculated.
  • the difference Z indicates whether the internal environment is hot or cool.
  • the internal temperature herein used may be the average of the temperature sensors D 1 and D 2 or the temperature of the temperature sensor D 2 alone. Otherwise, an additional thermometer may be provided.
  • step S 16 the programs proceeds to steps S 16 , S 17 and S 18 to stop the ceiling fan T 2 , open the top light T 1 to introduce outer air into the room, and keep the air-conditioner T 3 deactivated. These operations are carried out based on command signals applied from the controller C to the respective control units C 2 , C 1 and C 3 . If the internal environment is hot, in step S 19 , the ceiling fan T 2 is turned to generate an upward air current, and the top light T 1 is opened to replace inside air with outer air, with the air-conditioner T 3 deactivated.
  • step S 14 If it is determined in step S 14 that the internal temperature is not higher than the outside air temperature, it is determined in step S 20 whether the internal environment is cool. If the internal environment is cool, the ceiling fan T 2 is deactivated in step S 21 , and the top light T 1 is closed in step S 22 . If the internal environment is not cool, the program proceeds to steps S 23 , S 24 and S 25 to turn the ceiling fan T 2 , thereby generating an upward air current, open the top light T 1 for ventilation with the ceiling fan T 2 , and activate the air-conditioner T 3 for cooling.
  • step S 13 If it is determined in step S 13 that the temperature difference between the upper and lower portions of the room is e.g. not more than 3° C., the program proceeds to step S 30 in FIG. 5 to measure the difference between the temperatures inside and outside the room. If the internal temperature is lower, the program proceeds to step S 31 to determine whether the internal temperature is equal to or lower than the predetermined temperature. If it is, the program proceeds to steps S 32 , S 33 and S 34 to deactivate the ceiling fan T 2 , close the top light T 1 and deactivate the air-conditioner T 3 .
  • the program proceeds to steps S 35 , S 36 and then S 34 to turn the ceiling fan T 2 , thereby generating an upward air current, and open the top light T 1 for ventilation with the ceiling fan T 2 , with the air-conditioner T 3 deactivated.
  • step S 30 If it is determined in step S 30 that the internal temperature is higher than the outside air temperature, it is determined in step S 37 whether the internal temperature is equal to or lower than the predetermined temperature. If it is, the program proceeds to steps S 38 , S 39 and then S 34 to deactivate the ceiling fan T 2 , close the top light T 1 and deactivate the air-conditioner T 3 . Therefore, the interior of the room is kept in the unchanged state.
  • step S 37 If it is determined in step S 37 that the internal temperature is higher than the predetermined temperature, the program proceeds to steps S 40 , S 41 and then S 42 to turn the ceiling fan T 2 , thereby generating a downward air current, close the top light T 1 , and activate the air-conditioner T 3 for cooling.
  • steps S 40 , S 41 and then S 42 to turn the ceiling fan T 2 , thereby generating a downward air current, close the top light T 1 , and activate the air-conditioner T 3 for cooling.
  • cool air produced by air-conditioning is circulated throughout the room by the downward air current with the room interior shut out from the outer air.
  • the values of K1, K2 and K3 are not limited. According to their values, the degree of opening of the top light T 1 and the rotational speed of the ceiling fan T 2 may be changed stepwise, or the operational intensity of the air-conditioner may be changed over among “high”, “medium” and “low”. If the top light T 1 has a blind, the blind may be selectively closed and opened according to the amount of incoming sunlight as detected by an optical sensor.
