Abstract
Abstract Air conditioning apparatus, particularly for marine vessels, has an evaporator located so that minimum moisture occurs thereon at the location where there is maximum air flow thereacross to an air plenum discharge chamber. Condensate from the evaporator is automatically discharged through a sound suppressor to minimize noise. Components of the apparatus are arranged for maximum efficiency to attain miniaturization of the entire unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
Compact air conditioning apparatus comprising a housing having an air inlet means and at least one air outlet means, an evaporator positioned in the housing adjacent the air inlet means for cooling air which enters the housing there through, an intermediate wall in said housing adjacent the upper end of said evaporator, said wall dividing the interior of said housing into an upper plenum discharge chamber and a lower cooling chamber containing said evaporator, said wall having an opening, air blower means in said plenum chamber with suction side adjacent to said opening so that the maximum air disturbances produced in the cooling chamber occur adjacent the top of said evaporator, motor means located in said cooling chamber adjacent said evaporator and below said opening for energizing said air blower, and said upper plenum chamber communicating with said outlet means.
Claim 2
Dependent Claim
140 words
Compact air conditioning apparatus comprising a housing having an air inlet means and at least one air outlet means, an evaporator positioned in the housing adjacent the air inlet means for cooling air which enters the housing there through, an intermediate wall in said housing adjacent the upper end of said evaporator, said wall dividing the interior of said housing into an upper plenum discharge chamber and a lower cooling chamber containing said evaporator, said wall having an opening, air blower means in said plenum chamber with suction side adjacent to said opening so that the maximum air disturbances produced in the cooling chamber occur adjacent the top of said evaporator, motor means located in said cooling chamber adjacent said evaporator and below said opening for energizing said air blower, and said upper plenum chamber communicating with said outlet means.
Claim 3
Dependent Claim
91 words
Apparatus in accordance with claim 1 including means dividing said lower cooling chamber into first and second discrete compartments, said means dividing located adjacent the lower end of said evaporator, a heat exchanger in one of said compartments, a compressor, said evaporator and said motor means in the other compartment, conduit means defining a close circuit for a liquid refrigerant between said compressor and said heat exchanger and said evaporator, and means including conduits for enabling sea water to be pumped through said heat exchanger and discharged overboard from a vessel.
Claim 4
Dependent Claim
44 words
Apparatus in accordance with claim 2 wherein the depth of said housing is substantially less than the width of the housing, a compressor in said housing adjacent one end thereof, said opening in said intermediate wall being adjacent an opposite end of said housing.
Claim 5
Dependent Claim
43 words
Apparatus in accordance with claim 2 wherein said outlet means includes two discrete outlets from said plenum chamber, and a conduit connected to one of said outlets for transmitting air from the plenum chamber to a remote discharge point spaced from the housing.
Claim 6
Dependent Claim
54 words
Apparatus in accordance with claim 2 including a motor and pump coupled together and supported within said housing in depending relation from said intermediate wall, said motor being coupled to said blower means and, said pump, means for collecting condensate from said evaporator, and means for effecting withdrawal of collected condensation by said pump.
Claim 7
Dependent Claim
55 words
Apparatus in accordance with claim 2 including valve means in said conduit for alternately operating said evaporator in a heating or cooling mode, a high pressure cutoff in said conduit means for the discharge side of said compressor, and a low pressure cutoff in said conduit means between said valve means and said heat exchangers.
Claim 8
Dependent Claim
21 words
Apparatus in accordance with claim 2 wherein the depth of said housing is substantially less than the width of said housing.
Claim 9
Dependent Claim
135 words
Compact air conditioning apparatus comprising a housing having an air inlet means and at least one air outlet means, an evaporator positioned in the housing adjacent the air inlet means for cooling air which enters the housing there through, an intermediate wall in said housing adjacent the upper end of said evaporator, said wall dividing the interior of said housing into an upper plenum discharge chamber and a lower cooling chamber containing said evaporator, said wall having an opening, blower means associated with said opening for causing air to flow through said inlet means across said evaporator to said plenum chamber for discharge through said outlet means, means mounting said blower means at an elevation so that most of the warm air entering said inlet chamber flows across the upper end portion of said evaporator.
Claim 10
Dependent Claim
135 words
Compact air conditioning apparatus comprising a housing having an air inlet means and at least one air outlet means, an evaporator positioned in the housing adjacent the air inlet means for cooling air which enters the housing there through, an intermediate wall in said housing adjacent the upper end of said evaporator, said wall dividing the interior of said housing into an upper plenum discharge chamber and a lower cooling chamber containing said evaporator, said wall having an opening, blower means associated with said opening for causing air to flow through said inlet means across said evaporator to said plenum chamber for discharge through said outlet means, means mounting said blower means at an elevation so that most of the warm air entering said inlet chamber flows across the upper end portion of said evaporator.
