Abstract

A room air conditioner and/or heat pump is shown having a compressor, indoor coil, accumulator, expansion device and reversing valve for changing between a cooling cycle and a heating cycle. Intake louvers direct return air over the entire indoor coil for maximum heat transfer. Discharge louvers are curved upward to prevent short cycling while still being totally adjustable, up and down, right and left. Adjustment posts are anchored to a clip and are adjustable for right or left discharge of air and up or down discharge. Single handles control both the right or left discharge through a rear set of louvers and up or down discharge through a front set of louvers. A no circulation area prevents short cycling and curved edges prevent turbulence in air flow through louvers.

Claims (14)

1. A method of assembly and operation of a room air conditioner or heat pump unit having a compressor for compressing a refrigerant, an indoor coil for receiving said refrigerant there through, an outdoor coil for receiving said refrigerant there through, an accumulator on an intake side of said compressor, either of said indoor coil or said outdoor coil being an evaporator and the other being a condenser of said refrigerant, a fan for directing air through said outdoor coil, a blower for directing air through said indoor coil, the method comprising the following steps:

taking air into said unit through intake louvers on a front of a bezel as well as sides and bottom thereof to allow maximum heat exchange between air flowing through said indoor coil and said refrigerant;

discharging conditioned air from said unit through parallel discharge louvers on a front of said bezel, said parallel discharge louvers being located above said intake louvers on said front of said bezel, said parallel discharge louvers having a concave upper surface which directs air upward to prevent short cycling;

first directing said discharged conditioned air to a left or right on each side thereof;

second directing said discharged conditioned air up or down on each side thereof; and

said first and second directing steps being controlled by an adjusting handle on each side thereof, connecting said adjusting handle to a pivotable, slideable clip;

spacing said parallel discharge louvers on said front of said bezel a distance above said intake louvers to create a dead zone there between;

the method further including:

(a) clipping anchor bars onto said parallel discharge louvers said anchor bars holding adjusting handles for said first directing or said second directing steps;

(b) attaching connecting rods to said adjusting handles for moving vertical discharge louvers in said first directing step;

(c) smoothly positioning said adjusting handles on felt covered adjustment posts for moving said parallel discharge louvers during said second directing step;

(d) aligning posts of said bezel on said air conditioner or heat pump unit with alignment posts; and

(e) interchanging colors of said bezel with an interchangeable front door and top of said bezel.

2. The method as recited in claim 1 including a further step of rounding leading or trailing edges of said louvers to decrease air turbulence there through.
