            <description><![CDATA[A thin air outlet structure to a vehicle compartment exhibiting excellent directivity while ensuring sufficient volume and velocity of air conditioning air stream. In the air outlet structure 10, delivery direction of the air stream can be altered by altering the posture of a pair of fins 16 provided at a middle portion 13 in the flow direction in a case 12. Since the air outlet 20 does not require a plurality of fins for altering the delivery direction, the air outlet 20 can be made thin. Since the delivery direction of the air stream can be altered by means of the pair of fins 16 and the number of the fins 16 is small, flow of air is not impeded in the flow path within the case 12 and effective cross-sectional area of the flow path within the case 12 can be ensured. Consequently, sufficient volume and velocity of air stream can be secured. Furthermore, the size for each blade of the fins 16 can be increased by the decrease made in the number of fins 16. The air conditioning air stream excellent in directivity can be obtained.]]></description>

            <description><![CDATA[A multi-zone HVAC&R system has its control programmed to provide diagnostic testing of air handling components and refrigerant components associated with each climate controlled zone in sequence. The control changes the original position of the corresponding component and a resultant change in a relevant operational parameter is sensed. If the actual change is outside of the tolerance band associated with the expected change, then the determination is made that the component under consideration is malfunctioning. The periodicity of a diagnostic procedure for a particular component is typically defined by its criticality and reliability level. If the change in the corresponding operation parameter is recorded and stored in the database, the component degradation can be observed over time and a prognostic prediction can be made when a particular component requires preventive maintenance or replacement.]]></description>
