Abstract
Abstract Air cooling apparatus for use in boats which is resistant to corrosion, and comprises a unit having a compressor, condenser, evaporator, a positive condensate removal system and a cool air circulating fan and cooling water pump preferably driven by the same motor. The unit is mounted entirely within the boat, and uses the external water for cooling the condenser.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
217 words
Air conditioning apparatus for use in boats comprising an outer cabinet with air inlet and outlet openings, a motor driven compressor within the cabinet for compressing the gaseous refrigerant, a condenser for condensing the gaseous refrigerant to a liquid, an evaporator for causing the refrigerant to expand from a liquid to a gas, said evaporator and condenser being connected together to form a closed circuit for the refrigerant in said cabinet and in series with the compressor, water cooling means for said condenser including a discharge conduit for discharging water overboard, a pump in said cabinet for circulating water from the discharge side of the pump through said water cooling means to said discharge conduit, a fan in said cabinet for delivering air from said air inlet opening and through said air outlet opening in contact therebetween with said evaporator, driving means in said cabinet for said pump and fan, said evaporator having a condensate collecting member therebelow in said cabinet, and means in said cabinet including a fluid connection with said discharge conduit for effecting continuous removal of condensate from said collecting member for discharge overboard by way of said discharge conduit, said pump having an inlet conduit which has one end constructed and arranged for communication with water below the water line of a boat.

Dependent Claim
217 words
Air conditioning apparatus for use in boats comprising an outer cabinet with air inlet and outlet openings, a motor driven compressor within the cabinet for compressing the gaseous refrigerant, a condenser for condensing the gaseous refrigerant to a liquid, an evaporator for causing the refrigerant to expand from a liquid to a gas, said evaporator and condenser being connected together to form a closed circuit for the refrigerant in said cabinet and in series with the compressor, water cooling means for said condenser including a discharge conduit for discharging water overboard, a pump in said cabinet for circulating water from the discharge side of the pump through said water cooling means to said discharge conduit, a fan in said cabinet for delivering air from said air inlet opening and through said air outlet opening in contact therebetween with said evaporator, driving means in said cabinet for said pump and fan, said evaporator having a condensate collecting member therebelow in said cabinet, and means in said cabinet including a fluid connection with said discharge conduit for effecting continuous removal of condensate from said collecting member for discharge overboard by way of said discharge conduit, said pump having an inlet conduit which has one end constructed and arranged for communication with water below the water line of a boat.
Claim 3
Dependent Claim
58 words
Air conditioning apparatus in accordance with claim 1 wherein said last-mentioned means includes an aspirating member in said discharge conduit with said collecting member being connected adjacent the throat of said aspirating member by way of a flow passage having a non-return valve member so that condensate may flow only from said collecting member to said discharge conduit.
Claim 4
Dependent Claim
49 words
Air conditioning apparatus in accordance with claim 2 wherein said condensate collecting member for said evaporator includes a condensate collecting pan below the evaporator and at an elevation which is above the elevation of the condenser, and a pipe extending from said aspirating member to said condensate collecting pan.
Claim 5
Dependent Claim
43 words
Air conditioning apparatus in accordance with claim 1 including a common member to accommodate said discharge conduIt as well as the inlet conduit for said pump, and means for mounting said common member in the hull of a boat below the water line.
