Title:
LIGHTING-AIR CONDITIONING CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2010236821
Kind Code:
A
Abstract:

To prevent erroneous stop of an air conditioning device in a controlled space where person moves a little, such as an office space.

A radio variability monitoring device 6 is disposed on a prescribed position in the office space 1 for monitoring the variability of a reception level of transmitted radio waves (for example, TV airwaves) from an existing radio system (variability of level of received radio waves). When a state that the variability V of the level of the received radio waves is smaller than a threshold value S for a waiting time TW1 in the radio variability monitoring device 6, the reduction of air-conditioning capacity is not instructed to an air conditioning device controller 5, but only the reduction of lighting capacity is instructed to a lighting equipment controller 4 (for example, gradually lowering lighting intensity). Then when a state that the variability V of the level of the received radio waves is smaller than the threshold value S is continued for a waiting time TW2, the reduction of the lighting capacity to a low lighting capacity in absence (for example, extinction) is instructed to the lighting equipment controller 4, and the reduction of the air-conditioning capacity to a low air-conditioning capacity in absence (for example, stop) is instructed to the air-conditioning equipment controller 5.
