Abstract
Abstract In a self-contained air conditioner unit of the reversible refrigeration system type having cooling and heating cycles, a no-drain heat pump is provided wherein in the heating cycle, water collected on the outdoor heat exchanger operating as the system evaporator is transferred to the indoor section. The condensate is atomized and directed into the indoor air flow and against the relatively warm indoor heat exchanger operating as the condenser to humidify the air.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
281 words
A self-contained refrigeration heat pump air conditioning unit operable in a heating and cooling cycle for conditioning the air of an enclosure comprising: a chassis including a base member and a barrier dividing said chassis into an indoor compartment and an outdoor compartment; indoor and outdoor heat exchangers mounted respectively in said indoor and outdoor compartments; an indoor air moving means for recirculating enclosure air through said indoor compartment; an outdoor air moving means for circulating air through said outdoor compartment; a compressor mounted in said outdoor compartment; means for selectively connecting said compressor to said heat exchangers whereby said outdoor heat exchanger functions as an evaporator during operation of the unit on the heating cycle and said indoor heat exchanger functions as an evaporator during the cooling cycle; a condensate collection sump in said outdoor compartment formed in said base member being arranged to collect condensate from said indoor and outdoor heat exchangers; means for directing condensate formed on said indoor and outdoor heat exchangers into said sump; and condensate disposal means arranged in said oudoor compartment including a housing, passageway means connected to said housing at one end and having an outlet at the other end positioned in an opening in said barrier so as to communicate with the indoor compartment, condensate lifting means arranged on said housing including disc means operable in the heating cycle for lifting condensate from said sump and directing it into said passageway means and through said outlet in said indoor compartment into the path of air being circulated by said indoor fan where it is vaporized and directed through the relatively warm indoor heat exchanger functioning as a condenser in said heating cycle.
Claim 2
Dependent Claim

A self-contained refrigeration heat pump air conditioning unit operable in a heating and cooling cycle for conditioning the air of an enclosure comprising: a chassis including a base member and a barrier dividing said chassis into an indoor compartment and an outdoor compartment; indoor and outdoor heat exchangers mounted respectively in said indoor and outdoor compartments; an indoor air moving means for recirculating enclosure air through said indoor compartment; an outdoor air moving means for circulating air through said outdoor compartment; a compressor mounted in said outdoor compartment; means for selectively connecting said compressor to said heat exchangers whereby said outdoor heat exchanger functions as an evaporator during operation of the unit on the heating cycle and said indoor heat exchanger functions as an evaporator during the cooling cycle; a condensate collection sump in said outdoor compartment formed in said base member being arranged to collect condensate from said indoor and outdoor heat exchangers; means for directing condensate formed on said indoor and outdoor heat exchangers into said sump; and condensate disposal means arranged in said oudoor compartment including a housing, passageway means connected to said housing at one end and having an outlet at the other end positioned in an opening in said barrier so as to communicate with the indoor compartment, condensate lifting means arranged on said housing including disc means operable in the heating cycle for lifting condensate from said sump and directing it into said passageway means and through said outlet in said indoor compartment into the path of air being circulated by said indoor fan where it is vaporized and directed through the relatively warm indoor heat exchanger functioning as a condenser in said heating cycle.
Claim 3
Dependent Claim
77 words
The self-contained refrigeration heat pump air conditioning unit recited in claim 1 wherein said condensate disposal means further includes said housing having imperforate side and top walls, a motor mounted in said housing including a drive shaft extending through one of said housing side walls, a slinger disc mounted on said motor shaft having its lower circumferentially disposed edge portion positioned in said sump for lifting said condensate from said sump and directing it through said passageway.
Claim 4
Dependent Claim
62 words
The self-contained refrigeration heat pump air conditioning unit recited in claim 2 wherein said condensate disposal means further including said passageway being in alignment with said slinger disc, an inlet in said passageway being substantially smaller than said outlet so that said passageway diverges from said inlet toward said outlet to provide an unobstructed path for water spinning off said slinger disc.
