Abstract

The present application reveals a device for verifying a proper heat exchange and overall performance of an air-conditioning system. The device includes means for measuring a temperature differential between ambient and vent temperatures of the air-conditioning system, where the means comprises at least two remote probes for measuring the ambient and vent temperatures, or a remote ambient probe for measuring ambient temperatures and an integral vent probe for measuring vent temperatures; and means for analyzing the temperature differential in order to give an indication of performance of the air-conditioning system.

Claims

1. A device for verifying a proper heat exchange and overall performance of an air-conditioning system, comprising:

a) means for measuring a temperature differential between ambient and vent temperatures of the air-conditioning system, wherein said means comprises;

1) at least two remote probes for measuring the ambient and vent temperatures, or

2) a remote ambient probe for measuring ambient temperatures and an integral vent probe for measuring vent temperatures, or

3) a remote vent probe for measuring vent temperatures and an integral ambient probe for measuring ambient temperatures; and

b) means for analyzing the temperature differential in order to give an indication of performance of the air-conditioning system.

2. The device of claim 1, wherein a temperature differential of greater than 25°

F. between the ambient and vent temperature is determinative of whether the air-conditioning system is properly functioning.

3. The device of claim 1, further comprising an LCD readout for displaying the temperatures.

4. The device of claim 1, further comprising at least one LED.

5. The device of claim 1, further comprising means for indicating a pass/fail diagnosis.

6. The device of claim 1, further comprising at least three LEDs.

7. The device of claim 1, further comprising means for indicating a pass/acceptable/fail diagnosis.

8. The device of claim 2, further comprising means to automatically adjust the temperature differential for changing ambient temperatures using an algorithm, thereby changing a pass/fail indication point.
