Abstract
An air quality and temperature responsive air conditioning system wherein modules are employed to precondition the air for humidity control, to heat and cool the air, and to bypass the supply air in excess of the demand of a multiplicity of comfort zones with thermostat control, and featuring a bypass module characterized by parallel ducting, one ducting which is restricted by a damper responsive to a supply air back pressure sensor, and one ducting which is opened by a damper responsive to an air quality sensor.
Claims28
An air quality-temperature controlled central conditioning system having a return air inlet from and a supply air outlet to at least one comfort zone, and including;
- an air conditioning means receiving comfort zone air at the return air inlet and supplying tempered air pressured by a blower means through the supply air outlet,
- a damper module at the supply air outlet and modulated between closed and open positions to discharge air into the comfort zone in response to a temperature demand for said zone,
- parallel bypass ducts extending from the supply air outlet to the return air inlet, one a primary duct with a primary bypass damper means modulated between closed and open positions in response to supply air outlet pressure, and one a secondary duct with a secondary bypass damper means modulated between closed and open positions in response to an indoor air quality sensor means exposed to air of the comfort zone,
- and air filtration means in the secondary duct to remove pollutant matter from supply air recirculated to the return air inlet and through the air conditioning means.
An air quality-temperature controlled central conditioning system having a return air inlet from and a supply air outlet to at least one comfort zone, and including in combination:
- an air conditioning means receiving comfort zone air at the return air inlet and supplying tempered air pressured by blower means through the supply air outlet,
- a damper module at the supply air outlet and modulated between closed and open positions to discharge air into the comfort zone in response to a temperature demand for said zone,
- and an air bypass filtration module comprised of a unit having parallel bypass ducts extending from the supply air outlet to the return air inlet, one a primary duct with a primary bypass damper means modulated between closed and open positions in response to supply air outlet pressure, and one a secondary duct with a secondary bypass damper means modulated between closed and open positions in response to an indoor air quality sensor means exposed to air of the comfort zone, and air filtration means in the secondary duct to remove pollutant from the supply air recirculated to the return air inlet and through the air conditioning means.
A humidity-air quality-temperature controlled central conditioning system having a return air inlet from and a supply air outlet to at least one comfort zone, and including in combination;
- an outside air preconditioner comprising ventilation air ducting means for adding to the supply air entering the comfort zone, there being desiccant disposed therein for co-absorption of gasses and moisture, and exhaust air ducting means and desiccant disposed therein for regeneration by heating means and blower means transporting said ventilation air and exhaust air through said respective ducting means,
- an air conditioning means receiving comfort zone air through the return air inlet and supplying tempered air pressured by blower means through the supply air outlet,
- a damper module in the supply air inlet and modulated between closed and opened positions into the comfort zone in response to a temperature demand controlled means for said at least one comfort zone,
- parallel bypass ducts from the supply air outlet to the return air inlet, one a primary duct with a primary bypass damper means modulated between closed and opened positions in response to demand by a pressure sensor in the supply air outlet, and one a secondary inlet with a secondary bypass damper means modulated between closed and opened positions in response to an indoor air quality sensor means exposed to air of said at least one comfort zone,
- and air filtration means in the secondary duct to remove pollutant from supply air outlet air recirculated to the return air inlet and through the air conditioning means.
