Hvac system with fault detection and alert system

Abstract

Systems and methods utilized to create and perform an alert system in a heating, ventilation, and air conditioner (HVAC) system. One implementation includes a visual alert system to alert of a fault in the HVAC system. The system includes one or more LED lights indicating the fault and disposed on an exterior surface of a housing of the HVAC system. The system includes a programmable logic relay (PLR) having one or more relay outputs configured to activate, based on a type of the fault and according to fault/error codes, an alert notification. The alert system can operate without another device having a display for input and output, the other device displaying one or more parameters of the HVAC system. The system includes at least one of a high pressure switch, a low pressure switch, a differential air pressure switch, or an access panel switch.

What is claimed is: 
     
         1 . A fault detection and alert system to display a fault in a heating, ventilation, and air conditioner (HVAC) system, the system comprising:
 a plurality of LED lights indicating the fault and disposed on an exterior surface of a housing of the HVAC system; and   a programmable logic relay (PLR) having one or more relay outputs configured to activate, based on a type of the fault and according to fault codes, an alert notification having a pattern;   wherein the alert system operates without another device having a display for input and output, the other device displaying one or more parameters of the exterior HVAC system.   
     
     
         2 . The system of  claim 1 , further comprising at least one of a high pressure switch, a low pressure switch, a differential air pressure switch, or an access panel switch. 
     
     
         3 . The system of  claim 2 , wherein at least one of the PLR relay outputs is activated to control the LED lights in response to corresponding activation of at least one of a high pressure switch, a low pressure switch, a differential air pressure switch, or an access panel switch. 
     
     
         4 . The system of  claim 1 , wherein the alert notification pattern further comprises:
 at least one of switching a color of the LED light and an intermittent blinking of the LED light.   
     
     
         5 . The system of  claim 1 , wherein the PLR relay output performs at least one of turning on, turning off, or pulsating the PLR relays at a predetermined interval of time. 
     
     
         6 . The system of  claim 5 , wherein the predetermined interval of time is at least one of 1 second or 0.5 seconds. 
     
     
         7 . The system of  claim 1 , further comprising an LED power source. 
     
     
         8 . The system of  claim 1 , further comprising a filter having a sensor configured to indicate that a predetermined level of uncleanness is reached within the housing of the HVAC system. 
     
     
         9 . The system of  claim 1 , wherein the fault is a security threat. 
     
     
         10 . The system of  claim 1 , wherein the alert system indicates at least one of a high pressure, a low pressure, a dirty filter, or a security threat. 
     
     
         11 . The system of  claim 1 , further comprising one or more diffusers, the diffusers covering the LED lights. 
     
     
         12 . The system of  claim 11 , wherein the diffuser has an extended range of visibility. 
     
     
         13 . The system of  claim 1 , wherein the housing is water tight. 
     
     
         14 . The system of  claim 1 , further comprising more than one separate sections for disposing the LED lights therewithin. 
     
     
         15 . The system of  claim 1 , wherein at least some portion the LED lights can be formed in a shape of a company logo.
