Spot thermal or environmental conditioner
First Claim
1. In a building structure having a floor and a ceiling for limiting the vertical movement of the air in the space therebetween, the air temperature in the lower level floor zone of said space being lower than that in the upper level ceiling zone, and a housing having at least one compartment therein mounted substantially between said zones, a spot thermal conditioning apparatus selectively operable in warming and cooling modes, respectively, and comprisingfirst power means for flowing a first mass of said warm ceiling air into said compartment;
- second independent power means for concurrently flowing a second mass of said cool floor zone air into the compartment, said masses intersecting at an acute angle to form an air mixture having a temperature intermediate the temperatures of the air in said ceiling and floor zones;
said first means being positioned immediately adjacent said second means and causing said first mass to intersect said second mass in proximity to said second means;
means for varying the ratio between said flowing masses to cause predominantly warm ceiling air and subordinately cool floor air to be flowed into said mixture during the warming mode and subordinately warm ceiling air and predominantly cool floor air to be flowed into the mixture during the cooling mode, andmeans for projecting a concentrated high velocity stream of said air mixture horizontally and downwardly from said compartment, said stream being tightly focused toward an open spot work area substantially surrounded by said floor zone air.

Abstract
A spot thermal conditioning apparatus selectively operable in warming and cooling modes includes a housing containing a suction blower and a fan with radial blades. The suction blower receives ceiling air and projects an exiting stream of the ceiling air along one leg of an acute angle to an intersection. The fan is located substantially at the intersection and not only receives the exiting blower stream but also concurrently draws a stream of floor air substantially along the other leg of the angle to the intersection. The mixed air is then expelled through a louver to provide directional control of the movement of the conditioned air mass and circulation of air to an open spot work area. The suction blower and fan also each include an electronic speed control circuit so as to allow completely independent operation.

In a building structure having a floor and a ceiling for limiting the vertical movement of the air in the space therebetween, the air temperature in the lower level floor zone of said space being lower than in the upper level ceiling zone, and a housing having at least one compartment therein mounted substantially between said zones, a spot thermal conditioning apparatus selectively operable in warming and cooling modes, respectively, and comprising
