Abstract
An air conditioning system comprising a heat exchanger using the conduction principle to impart a portion of the heating or cooling from the air exhausted from a building or facility to a make-up air supply and a heat pump which provides supplemental heating or cooling for the make-up air supply to bring it to the desired temperature for use in the building or facility.
Claims2
An air conditioning system for heating and cooling the air in an enclosed area;
- means for exhausting a portion of the air from the enclosed area;
- an outlet from which the air exhausted from the enclosed area is discharged;
- an inlet for supplying ambient make-up air to the system to replace the air discharged;
- a heat exchanger disposed between the exhaust means and the discharge outlet to enable the exhaust air passing therethrough to treat the make-up air by conduction;
- means for introducing the treated make-up air to the enclosed area;
- a heat pump in the system for providing supplemental treatment of the make-up air to that induced by the heat exchanger;
- said heat pump embodying a compressor;
- a first coil member disposed in the path of the exhaust air between the heat exchanger and the discharge outlet and alternating as an evaporator and a condenser;
- a second coil member disposed in the path of the make-up air between the heat exchanger and the blower for introducing the make-up air to the enclosed area and alternating as a condenser and an evaporator;
- and valve means operating alternately to direct the flow of fluid through the first and second coil members thereby providing heating and cooling as required for the make-up air supply.
