Interior temperature control system

Abstract

It is aimed 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. A top light T 1 , a ceiling fan T 2 and an air-conditioner T 3 are installed in or on a house 1 . A controller C controls the interior temperature by performing computing, and selectively opening and closing the top light T 1 , selectively rotating the ceiling fan T 2 in one or the opposite direction, and selectively activating and deactivating the air-conditioner T 3 , based on signals from a temperature sensor D 1 provided at an upper portion of the room, a temperature sensor D 2 provided at a lower portion of the room, and a temperature sensor D 3 provided outside the room.

       3 . An interior temperature control system comprising a top light T 1 , a ceiling fan T 2  and an air-conditioner T 3  that are installed in or on a house  1 , and a controller C for controlling the internal temperature by performing computing, and selectively opening and closing the top light T 1 , selectively rotating the ceiling fan T 2  in one or the opposite direction, and selectively activating and deactivating the air-conditioner T 3 , based on signals from a temperature sensor D 1  provided at an upper portion of the room, a temperature sensor D 2  provided at a lower portion of the room, and a temperature sensor D 3  provided outside the room, in the following steps:
 (1) the step of determining the difference X between the temperatures of the upper and lower portions of the room, the difference Y between the temperatures inside and outside the room, and the difference Z between the internal temperature and the predetermined temperature, based on input signals from the temperature sensors D 1 , D 2  and D 3 ;   (2) the step of determining whether the difference X is not less than K1 (constant value);   (3) the step of determining whether the difference Y is less than K2 (constant value) if in the step (2), the difference X is not less than K1;   (4) the step of determining whether the difference Z is less than K3 (constant value) if in the step (3), the difference Y is determined to be less than K2;   (5) the step of deactivating the ceiling fan T 2 , opening the top light T 1  to introduce outer air into the room, and deactivating the air-conditioner T 3  if in the step (4), the difference Z is determined to be less than K3 (constant value);   (6) the step of turning the ceiling fan T 2 , thereby generating an upward air current, opening the top light T 1 , thereby replacing air in the room with outer air, and deactivating the air-conditioner T 3  if in the step (4), the difference Z is determined to be not less than K3 (constant value);   (7) the step of determining whether the difference Z is less than K3 (constant value) if in the step (3), the difference Y is determined to be not less than K2;   (8) the step of deactivating the ceiling fan T 2  and closing the top light T 1  if in the step (7), the difference Z is determined to be less than K3 (constant value);   (9) the step of turning the ceiling fan T 2 , thereby generating an upward air current, opening the top light T 1  for ventilation with the ceiling fan T 2 , and activating the air-conditioner for cooling, if in the step (7), the difference Z is determined to be not less than K3 (constant value);   (10) the step of determining whether the difference Y is not less than K2 (constant value) if in the step (2), the difference X is less than K1;   (11) the step of determining whether the difference Z is less than K3 (constant value) if in the step (10), the difference Y is determined to be not less than K2 (constant value);   (12) the step of deactivating the ceiling fan T 2 , closing the top light T 1 , and deactivating the air-conditioner T 3  if in the step (11), the difference Z is determined to be less than K3 (constant value);   (13) the step of turning the ceiling fan T 2 , thereby generating an upward air current, opening the top light T 1  for ventilation with the ceiling fan T 2 , and keeping the air-conditioner T 3  deactivated, if in the step (11), the difference Z is determined to be not less than K3 (constant value);   (14) the step of determining whether the difference Z is less than K3 (constant value) if in the step (10), the difference Y is determined to be less than K2 (constant value);   (15) the step of deactivating the ceiling fan T 2 , closing the top light T 1 , and deactivating the air-conditioner T 3  if in the step (14), the difference Z is determined to be less than K3 (constant value); and   (16) the step of turning the ceiling fan T 2 , thereby generating a downward air current, closing the top light T 1 , and activating the air-conditioner T 3  for cooling if in the step (14), the difference Z is determined to be not less than K3 (constant value).
