Abstract

ABSTRACT

In computer rooms, it is necessary to provide both air con-ditioning equipment and fire detection/extinguishing equip-ment. These until now have been separate from each other.
The utility of this invention is to package both systems to-gether making use of the air handling part of the air con-ditioner in both the fire sensing and dispersion of the ex-tinguishing agent. This agent is known as Halon 1301.

Description

SPECIFICATION
This invention relates to a combination computer room air conditioner, fire sensing and extinguishing system which interact being combined into one package. It is now common to have both systems completely separate re-sulting in less effective fire sensing and dispersion of the extinguishing agent and higher installa-tion costs.
I have found that these disadvantages may be overcome by packaging the two systems together and making use of the air handling portion of the air conditioner. As detailed in Figure 1 which is a table of the 17 main parts of the system and Figure 7 which shows the relationship of these major components: Two fire detectors (Firetek Model 303-2135 dual chamber, 24 volt ionization type) shall be crossed-zoned that any one detector upon detection shall give audio-visual alarm (See Figure 4 which details the unit's monitor/
malfunction lights and audio alarm) and when both are trig-gered together will discharge the extinguishing agent into the air from the Halon 1301 container through 2" diameter schedule 40 pipe and discharge nozzle into the area after the evaporator coil within the air conditioner (See Figure 7).
The blower fan (See Figure 7) will then quickly assist in dispersement of the extinguishment agent throughout the covered area. The air conditioner which comprises the first and second compressors, the condenser coil, the evaporator coil, the reheat coil, the humidifier, the return air duct, 07~

SPECIFICATION
the blower, the filter, the electric control panel, the temperature-humidity stats and the control/malfunction monitor shall continue to operate as usual however with the additional alarm status function incorporated into the unit control/
malfunction panel. (See Figure 3 which details the location of the panel and Figure 4 which details the panel) PREAMBLE TO DRAWINGS

Claims

Claim The embodiments of the invention in which an exclusive property or privilege is claimed and defined as follows:

1. "In combination, an air-conditioning system and fire sensing-extinguishing system package unit, wherein the two systems are packaged together to make use of the air handling part of the air-conditioning system in both air conditioning and fire-sensing plus dispersion of extinguishing agent, comprising:
cabinet enclosure means, for housing both an air-conditioning system and a fire sensing extinguishing system, first and second compressor for redundant compression/
pumping of refrigerant, condenser coil for removal of the heat gained from the refrigerant, evaporator coil for cooling/dehumidification of incoming air, humidifier for supplying moisture to the air, electrical reheat coils for heating/dehumidification of the air, return air duct means and blower means for effecting movement of air through the system, filter means for filtering air, temperature/humidity stats, electrical control panel to house the controls, Claim a single electronic control/malfunction monitor, including audio alarm for indicating fire, cooling, heating, humidification, dehumidification, blower, filter, ionization detector, Halon discharge, discharge means including Halon 1301 container, a length of pipe and one single Halon discharge nozzle, responsive to said monitor, and two cross-zone ionization fire detectors, for detection of smoke within the incoming air."

2.The common unit as defined in Claim 1 which automatically sense and adapt its internal elements to function together to cool, heat, humidify, dehumidify, filter, and disperse extinguishing agent (Halon 1301) as required and determined by the set points within the control/malfunction monitor.
