1. A central air conditioning system for conditioning air in a building comprising:
- the building having an interior space isolated from an exterior of said building;
a central air conditioning unit of predetermined capacity operatively connected to said building;
an input air duct extending from the interior of said building to said central air conditioning unit, said input duct having a blocking air damper valve therein adapted to shut off a flow of air therethrough;
an output air duct extending from said central air conditioning unit into the interior of said building, said output duct having a blocking air damper valve therein adapted to shut off a flow of air therethrough;
an outside air duct extending from outside said building to said central air conditioning unit, said outside air duct having a blocking air damper valve therein adapted to shut off a flow of air therethrough;
a fire suppression air duct extending from said central air conditioning unit output air duct to outside said building, said fire suppression air duct having a blocking air damper valve therein adapted to shut off a flow of air therethrough;
an air conditioner control processor operatively connected to said input air duct blocking air damper valve, said output air duct blocking air damper valve, said exterior air duct blocking air damper valve and said fire suppression air duct blocking air damper valve;
said air conditioner control processor being adapted to;
turn off said outside air duct blocking air damper valve and said fire suppression air duct blocking air damper valve when said air conditioning system is operating in normal operation mode with the air flow through the open input air duct and output air duct, andto turn off said input air duct blocking air damper valve and said fire suppression air duct blocking air damper valve and to open said outside air duct blocking air damper valve when said air conditioning system is operating in outside air conditioning mode with the air flow through the open outside air duct and output air duct, andto turn off said output air duct blocking air damper valve and said outside air duct blocking air damper valve and to open said fire suppression air duct blocking air damper valve and said interior air duct blocking air damper valve when said air conditioning system is operating in fire suppression mode with air flow through the open input air duct and fire suppression air duct;
whereby the air in the building is adapted to be conditioned with outside air and to have hazardous air evacuated therefrom.

Abstract
The present invention relates to controlling the treatment of air for the inside of a building and especially to controlling a hybrid air conditioning system for the regulation of the air temperature and humidity which utilizes outside air to enhance the efficiency of the system and which has a smoke evacuation system to enhance the safety of firemen and occupants when there is a fire or smoke hazard in the building.
