An air heating and humidifying system and method using direct contact heating principles. The system consists in providing a source of hot water by feeding hot flue gases in a direct contact water heater and wherein the water sprayed over a packing in the water heater is heated as it percolates through the packing and is in contact with the hot rising flue gases. This hot water from the direct contact water heater is used in a direct contact air treating chamber wherein it is sprayed over a further packing whereby to heat and humidify fresh air which is pushed through the packing by a fan and exits at an outlet flue of the treating chamber to supply hot moist fresh air in a building air conditioning system. The cooled water in the direct contact air treating chamber is collected and supplies the spray nozzle of the direct contact water heater to cool the hot flue gases which are rising therein and thereby enhances considerably the efficiency of the direct contact water heater.
An air heating and humidifying system using direct contact heating apparatus, said system comprising a direct contact water heater having heat exchange means therein, a water spray means above said heat exchange means to supply water thereto and to cause water to percolate through said heat exchange means and heat by contact therewith, a hot gas heat supply below said heat exchange means for heating said heat exchange means and water percolating downwards to a reservoir below said heat supply to produce a supply of hot water, a flue to exhaust cooled flue gases from said water heater, pump means to direct hot water from said reservoir above a further heat exchange means in a direct contact air treating chamber to heat and humidify fresh air passing through said further heat exchange means to provide a supply of hot moist fresh air at an outlet port of said air treating chamber.
A method of producing hot humidified air using direct contact heating principles, said method comprising the steps of:
