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. Thus, the system features a double-sealing system with a unique automatic safety valve which releases the refrigerant only when the indoor and outdoor components are connected and sealed, thus avoiding any potential leakage.

I claim: 
     
         1 . A self-contained refrigerant connection system for installation of a ductless HVAC system to a structure comprising:
 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;   wherein the hole slopes five degrees downward from the interior wall to the exterior wall;   placing a protective wall cuff into the hole;   wrapping pre-charged refrigerant piping, a drain pipe, and a signal cable into a bundle;   wherein the pre-charged refrigerant piping contains pre-balanced refrigerant which does not require additional charging upon installation;   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;   wherein the pre-charged refrigerant piping has two ends;   wherein the pre-charged refrigerant piping is equipped with two female quick-connect connectors, one disposed at each end;   wherein each female quick-connect connector is equipped with a coupling, a spring, a housing, and a pin;   wherein the housing contains the spring and the pin;   wherein the coupling is configured to accept a male quick-connect connector;   wherein male quick-connect connectors are disposed on the outdoor unit and the indoor unit;   connecting the female quick-connect connectors of the pre-charged refrigerant piping of the bundle to the male quick-connect connectors of the outdoor unit;   wherein, upon connection of the female quick-connect connectors to the male quick-connect connectors, the pins of each female quick-connect connector are depressed, opening internal quick-release valves of the pre-charged refrigerant piping;   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; and   connecting the power cable of the outdoor unit to a household power supply.
