Hoseless Wireless Gauges for HVAC Maintenance and Repair

Abstract

A measurement device for use in the HVAC field that incorporates a one or more remote sensors to measure physical properties such as system pressure and coolant temperature.

1 . A device for measuring and remotely displaying HVAC system data comprising:
 a sensor unit capable of acquiring physical characteristic data of the HVAC system and transmitting the data measured;   a remote display for receiving the data transmitted by the sensor unit.   
     
     
         2 . The device of  claim 1 , wherein the sensor unit measures coolant pressure. 
     
     
         3 . The device of  claim 2 , wherein the sensor unit is connected to a coolant access point of the HVAC system 
     
     
         4 . The device of  claim 1 , wherein the sensor unit further comprises a microcontroller and a communications module. 
     
     
         5 . The device of  claim 4  wherein the communications module uses the Bluetooth® communications protocol 
     
     
         6 . The device of  claim 1 , wherein the sensor unit is connected to an HVAC system in such a manner as to measure the temperature of the coolant in the HVAC system. 
     
     
         7 . The device of  claim 1  wherein the remote display is a wireless telephone 
     
     
         8 . The device of  claim 1 , wherein the remote display is a smart phone running an application program that displays the received data. 
     
     
         9 . The device of  claim 7  wherein the wireless telephone uses a software application program for receiving the transmitted data 
     
     
         10 . A method of measuring and remotely displaying data comprising, the steps of:
 connecting a sensor unit capable of measuring and transmitting data related to a physical characteristic of an HVAC system to a an HVAC device for which the physical characteristic is to be measured.   receiving the data related to a physical characteristic on a remote display   
     
     
         11 . The method of  claim 10  wherein the physical characteristic measured is coolant pressure. 
     
     
         12 . The method of  claim 10  wherein the sensor unit further comprises a microcontroller and a communications module. 
     
     
         13 . The method of  claim 12  wherein the communications module uses the Bluetooth® 
     
     
         14 . The method of  claim 10  wherein the sensor unit measures the temperature of the coolant in the HVAC system. 
     
     
         15 . The method of  claim 10  wherein the remote display is a wireless telephone. 
     
     
         16 . The method of  claim 10  wherein the remote display is a smart phone capable of running a software application program to display the received data.
