Device and method for taking multiple temperature HVAC readings

1. A device for taking temperature readings on an HVAC system, comprising:

a manifold configured to be connectable in fluid communication with an HVAC system;

a first probe configured to be connectable in thermal communication with an HVAC system for taking a first temperature reading thereof, the first probe comprising a first sensor clamp that is removably attachable to the manifold for sensing a first temperature of the HVAC system;

a second probe configured to be connectable in thermal communication with an HVAC system for taking a second temperature reading thereof that is independent of the first temperature reading, the second probe comprising a second sensor clamp that is removably attachable to the manifold for sensing a second temperature of the HVAC system; and

at least one display connectable to the first and second probes for displaying the first and second temperature readings wherein the display generates color-coded temperatures, each color separately corresponding to a different refrigerant type.

2. A device as defined in claim 1 , wherein each probe includes a thermocouple.

3. A device as defined in claim 1 , wherein at least one of (i) the first and second probes are configured to take the first and second temperature readings substantially simultaneously and (ii) the display substantially simultaneously displays the first and second temperature readings.

4. A device as defined in claim 1 , wherein the first and second probes extend outwardly from the manifold and are configured to be operably connected to the HVAC system for taking the temperature readings.

5. A device as defined in claim 1 , wherein the device is configured to calculate super-heated and sub-cooled refrigerant temperatures.

6. A device as defined in claim 1 , wherein the device is configured to be at least one of: (i) solar powered with battery backup, and (ii) fully battery powered for low light environments.

7. A device as defined in claim 1 , wherein the device includes a solar array configured to solar power the display and/or first and second probes.

8. A device as defined in claim 1 , wherein the first and second probes generate digital signals indicative a temperature taken thereby.

9. A device as defined in claim 1 , wherein the manifold includes first and second gauges, and the display is mounted between the first and second gauges.

10. A device as defined in claim 9 , wherein the first and second gauges are analog, and the display is digital.

11. A device as defined in claim 1 , further including at least one sealing member configured to form a fluid-tight seal between the manifold and the HVAC system when attached.

12. A device as defined in claim 11 , wherein the manifold further includes a torque-limiting handle that securely closes and forms a fluid tight seal between the sealing member and HVAC system when attached but substantially prevents damage to the sealing member by over-tightening.

13. A device as defined in claim 1 , wherein the display is one of (i) fixedly secured in a generally central region of the manifold and (ii) removably attachable to a generally central region of the manifold, and is configured to substantially simultaneously display the first and second temperature readings.

14. A device as defined in claim 13 , wherein the display is both attachable to and detachable from the generally central region of the manifold.

15. A device as defined in claim 1 , wherein the device includes at least one fastener configured to attach the display to the HVAC manifold.

16. A device as defined in claim 15 , wherein the fastener is at least one of: (i) hook shaped for engaging and attaching the display to the HVAC manifold; (ii) snap fits to the HVAC manifold for engaging and attaching the display thereto; (iii) a clip for engaging and attaching the display to the HVAC manifold; and (iv) attachable to a gauge cover for attaching the display to the HVAC manifold.

17. A method comprising the following steps:

connecting an HVAC manifold to an HVAC system;

taking a first temperature reading of the HVAC system by attaching to the manifold a first sensor clamp that is removably attachable to the manifold for sensing a first temperature of the HVAC system;

taking a second temperature reading of the HVAC system that is independent of the first temperature reading by attaching to the manifold a second sensor clamp that is removably attachable to the manifold for sensing a second temperature of the HVAC system; and

displaying the first and second temperature readings on a display operatively connected to the HVAC manifold including generating color-coded temperatures where each color separately corresponds to a different refrigerant type.

18. A method as defined in claim 17 , wherein the displaying step includes substantially simultaneously displaying the first and second temperature readings.

19. A method as defined in claim 18 , further comprising taking the first and second temperature readings substantially simultaneously.
