Abstract

Abstract A system for supplying treated air to an enclosure including a heat exchanger through which a heat exchange medium flows and a fan arranged to route air to be treated over the heat exchanger in heat transfer relation with the medium. A control operates to vary the speed of the fan in response to changes in room temperature. At least one outlet is provided for discharging the treated air from the system, the outlet being positioned so that the treated air is discharged with minimal turbulence substantially adjacent and parallel to the ceiling of the enclosure.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 174 words
A method of regulating the temperature of air circulating within an enclosure having communication with a structure serving as an air passage and provided with at least one outlet through which treated air is delivered, comprising the steps of: A. passing air to be treated through a heat exchanger in heat transfer relation with either a relatively warm heat exchange medium or a relatively cold heat exchange medium; B. sensing the temperature of the air in the enclosure; C. creating a control signal which is a function of the sensed temperature; D. varying the quantity rate of air passing through said heat exchanger, the magnitude thereof being a function of the control signal; and E. discharging the treated air from the air passage substantially adjacent to the ceiling of the enclosure to cause the treated air stream to adhere to the ceiling and flow therealong to substantially uniformly mix with the treated air in the enclosure irrespective of the quantity of treated air delivered to the air passage and irrespective of the temperature thereof.
Claim 2
Independent Claim 174 words
A method of regulating the temperature of air circulating within an enclosure having communication with a structure serving as an air passage and provided with at least one outlet through which treated air is delivered, comprising the steps of: A. passing air to be treated through a heat exchanger in heat transfer relation with either a relatively warm heat exchange medium or a relatively cold heat exchange medium; B. sensing the temperature of the air in the enclosure; C. creating a control signal which is a function of the sensed temperature; D. varying the quantity rate of air passing through said heat exchanger, the magnitude thereof being a function of the control signal; and E. discharging the treated air from the air passage substantially adjacent to the ceiling of the enclosure to cause the treated air stream to adhere to the ceiling and flow therealong to substantially uniformly mix with the treated air in the enclosure irrespective of the quantity of treated air delivered to the air passage and irrespective of the temperature thereof.
Claim 3
Dependent Claim 234 words
An air conditioning system for supplying treated air to a conditioned space, comprising: A. means for sensing the temperature of the air in the conditioned spaCe; B. means for supplying a control signal which is a function of the sensed temperature; C. means for receiving the control signal; D. means operable to produce treated air, the quantity of treated air being a function of the control signal, said means being selectively operable to provide either relatively warm air for heating the conditioned space or relatively cool air for cooling same; E. supply means for delivering the treated air to the conditioned space, said supply means including a pressurized chamber; and F. discharge means communicating the conditioned space with said pressurized chamber, said discharge means having a first member spaced from the ceiling of the conditioned space so as to define an air passage between said member and said ceiling so that the treated air is discharged parallel to and substantially adjacent to the ceiling, means operable to vary the area of said discharge means, said last mentioned means being responsive to the pressure of the treated air in the pressurized chamber, said discharge means causing treated air passing therethrough to adhere to the ceiling and flow therealong to substantially uniformly mix with air in the conditioned space irrespective of the quantity of air delivered to the pressurized chamber and irrespective of the temperature thereof.
Claim 4
Dependent Claim 234 words
An air conditioning system for supplying treated air to a conditioned space, comprising: A. means for sensing the temperature of the air in the conditioned spaCe; B. means for supplying a control signal which is a function of the sensed temperature; C. means for receiving the control signal; D. means operable to produce treated air, the quantity of treated air being a function of the control signal, said means being selectively operable to provide either relatively warm air for heating the conditioned space or relatively cool air for cooling same; E. supply means for delivering the treated air to the conditioned space, said supply means including a pressurized chamber; and F. discharge means communicating the conditioned space with said pressurized chamber, said discharge means having a first member spaced from the ceiling of the conditioned space so as to define an air passage between said member and said ceiling so that the treated air is discharged parallel to and substantially adjacent to the ceiling, means operable to vary the area of said discharge means, said last mentioned means being responsive to the pressure of the treated air in the pressurized chamber, said discharge means causing treated air passing therethrough to adhere to the ceiling and flow therealong to substantially uniformly mix with air in the conditioned space irrespective of the quantity of air delivered to the pressurized chamber and irrespective of the temperature thereof.
