Apparatus and process for amateur ductless hvac installation

Abstract

A ductless HVAC system solution is described. The system is configured for easy installation by an amateur, and therefore does not require a license, expensive tools, or much time to install. The system is equipped with pre-charged refrigerant piping, which are designed to contain the recommended pressure of requisite refrigerant. A quick-release valve system ensures refrigerant does not leak from the pre-charged refrigerant piping during installation by an amateur. The system may be controlled manually or remotely via WiFi.

I claim: 
     
         1 . A ductless HVAC system comprising:
 an indoor unit, said indoor unit extends through an outer wall of a location of installation of the ductless HVAC system; (Change to “connected to outdoor unit through a wall)   an outdoor unit, said outdoor unit disposed outside of said location of installation;   pre-charged refrigerant piping, said refrigerant lines extending between said indoor unit and said outdoor unit;   wherein said pre-charged refrigerant piping contains refrigerant restricted within the pre-charged refrigerant piping by a first quick-release valve, and a second quick release valve;   refrigerant piping connection valves, said refrigerant piping connection valves disposed on said outdoor unit and said indoor unit;   at least one power cable, said at least one power cable in communication with said indoor unit and said outdoor unit;   wherein said at least one power cable conveys electricity to said indoor unit and said outdoor unit;   a signal cable, said signal cable in communication with said indoor unit and said outdoor unit;   wherein said refrigerant piping connection valves are open when said pre-charged refrigerant piping is interfaced with said indoor unit and said outdoor unit, releasing refrigerant into the system; and   wherein installation does not require presence of a certified HVAC professional.   
     
     
         2 . The system of  claim 2 , further comprising:
 a first pre-charged refrigerant pipe, said second pre-charged refrigerant pipe equipped with a first end labeled ‘A’ and a second end labeled ‘B’;   a second pre-charged refrigerant pipe, said second pre-charged refrigerant pipe equipped with a first end labeled ‘C’ and a second end labeled ‘D’;   a first valve, said first valve disposed at said first end labeled ‘A’ of said first pre-charged refrigerant pipe;   a second valve, said second valve disposed at said second end labeled ‘B’ of said first pre-charged refrigerant pipe;   a third valve, said third valve disposed at said first end labeled ‘C’ of said second pre-charged refrigerant pipe;   a fourth valve, said fourth valve disposed at said second end labeled ‘D’ of said second pre-charged refrigerant pipe;   a first pipe connection point, said first pipe connection point disposed on said outdoor unit;   a second pipe connection point, said second pipe connection point disposed on said outdoor unit, above said first pipe connection point;   a fifth valve, said fifth valve disposed within said first pipe connection point;   a sixth valve, said sixth valve disposed within said second pipe connection point;   a third pipe connection point, said third pipe connection point disposed on said indoor unit;   a fourth pipe connection point, said fourth pipe connection point disposed on said indoor unit, adjacent to said third pipe connection point;   a seventh valve, said seventh valve disposed within said third pipe connection point; and   an eighth valve, said eighth valve disposed within said fourth pipe connection point.   
     
     
         3 . The system of  claim 2 , wherein said refrigerant of said first pre-charged refrigerant pipe and said second pre-charged refrigerant pipe is released to said indoor unit and said outdoor unit when said first valve, said second valve, said third valve, said fourth valve, said fifth valve, said sixth valve, said seventh valve, and said eighth valve are open. 
     
     
         4 . The system of  claim 2 , wherein said first valve, said second valve, said third valve, and said fourth valve are opened automatically upon securely seating said first pre-charged refrigerant pipe, said second pre-charged refrigerant pipe via connection points A, B, C, and D to said first pipe connection point, said second pipe connection point, said third pipe connection point, and said fourth pipe connection point respectively. 
     
     
         5 . The system of  claim 4 , wherein said first pipe connection point is labeled ‘A;’
 wherein said second pipe connection point is labeled ‘B;’ 
 wherein said third pipe connection point is labeled ‘C;’ and, 
 wherein said fourth pipe connection point is labeled ‘D.’ 
 
     
     
         6 . A process for installing a ductless HVAC system comprising:
 selecting an installation location within a structure;   attaching a mounting plate to an interior wall of the structure at the selected installation location;   drilling a hole through the interior wall which passes through an exterior wall, the hole being adjacent to the mounting plate;   placing a protective wall cuff into the hole;   wrapping pre-charged refrigerant piping, a drain pipe, and a signal cable into a bundle;   feeding the bundle through the hole;   attaching an indoor unit to the mounting plate;   wherein the indoor unit is an air handler;   wherein said pre-charged refrigerant piping, drain pipe, and signal cable are affixed to the indoor unit;   wherein said drain pipe is disposed at a bottom of the bundle;   placing an outdoor unit on a solid surface, outside of the structure, below the hole;   anchoring the outdoor unit to the solid surface;   connecting the signal cable of the bundle to a signal cable terminal of the outdoor unit;   connecting a power cable to a power cable terminal block of the outdoor unit;   connecting the pre-charged refrigerant piping of the bundle to pre-charged refrigerant piping connectors of the outdoor unit;   opening internal quick-release valves of the pre-charged refrigerant piping automatically upon connection of the pre-charged refrigerant piping to the pre-charged refrigerant piping connectors of the outdoor unit;   turning valves disposed on the outdoor unit to an open position, releasing refrigerant from the pre-charged refrigerant piping into the outdoor unit;   turning valves disposed on the indoor unit to an open position, releasing refrigerant from the pre-charged refrigerant piping into the indoor unit;   wherein the outdoor unit contains a condenser;   connecting a power cable of the indoor unit to a household power supply;   connecting the power cable of the outdoor unit to a household power supply;   checking the system for leaks; and   activating the system via a control.
