Abstract

Abstract A combination air conditioner comprising a refrigeration type air conditioner and an evaporatively cooled type air conditioner wherein the evaporatively cooled air conditioner is spaced from the condenser of the refrigeration type air conditioner so as not to substantially interfere with air flow through said condenser normal to the operation of said refrigeration type air conditioner. The evaporative cooler so spaced from the condenser being adapted to deliver evaporatively cooled air to the condenser to augment thermal dynamic operation thereof. Additionally, the evaporative cooler is provided with means adapted to operate the fan thereof only without evaporative cooling, to augment operation of the condenser by increasing airflow thereover. Control means for the evaporative cooler comprising a plurality of temperature responsive devices adapted to cause the fan of the evaporative cooler to force air towards said condenser at a plurality of different elevated temperatures and a further temperature responsive switch is also adapted to operate the pump of the evaporative cooler to deliver water to the evaporative cooler pads thereof for maximum augmentation of the condenser operation by the evaporative cooler.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 171 words
In a combination air conditioner, a refrigeration-type air conditioner having a refrigerant condenser, said refrigerant condenser provided with an inlet and an outlet; a refrigerant evaporator; a refrigerant vapor compressor coupled with said condenser and evaporator; said inlet of said refrigerant condenser communicating with outside ambient atmosphere; first means for forcing ambient air from atmosphere through said condenser from said refrigerant condenser inlet to said refrigerant condenser outlet and exhausting said ambient air to atmosphere; an evaporative type air cooler having an evaporative cooler pad; pump means for delivering water to said pad; second means for forcing air from ambient atmosphere through said pad and for delivering air toward said inlet of said refrigerant condenser for augmenting operation of said first means to thereby increase air flow through said refrigerant condenser; said evaporative type air cooler and said second means spaced from said refrigerant condenser a distance so as not substantially to interfere with normal ambient air flow througH said refrigerant condenser as may be forced therethrough by said first means.
Claim 2
Dependent Claim 171 words
In a combination air conditioner, a refrigeration-type air conditioner having a refrigerant condenser, said refrigerant condenser provided with an inlet and an outlet; a refrigerant evaporator; a refrigerant vapor compressor coupled with said condenser and evaporator; said inlet of said refrigerant condenser communicating with outside ambient atmosphere; first means for forcing ambient air from atmosphere through said condenser from said refrigerant condenser inlet to said refrigerant condenser outlet and exhausting said ambient air to atmosphere; an evaporative type air cooler having an evaporative cooler pad; pump means for delivering water to said pad; second means for forcing air from ambient atmosphere through said pad and for delivering air toward said inlet of said refrigerant condenser for augmenting operation of said first means to thereby increase air flow through said refrigerant condenser; said evaporative type air cooler and said second means spaced from said refrigerant condenser a distance so as not substantially to interfere with normal ambient air flow througH said refrigerant condenser as may be forced therethrough by said first means.
Claim 3
Dependent Claim 86 words
The invention as defined in claim 1 wherein said refrigeration type air conditioner is adapted for optimum performance at a designed temperature; and temperature responsive means coupled with and adapted to control operation of said second means of said evaporative type air conditioner; said temperature responsive means adapted to respond to an elevated temperature above said design temperature and to thereby energize said second means to deliver additional air toward said condenser to thereby increase air flow therethrough and to augment operation of said first means.
Claim 4
Dependent Claim 59 words
The invention as defined in claim 2 wherein second temperature responsive means is adapted to respond to a further elevated temperature above said first mentioned elevated temperature; said second temperature responsive means adapted to energize said second means at a higher rate to further increase flow toward said condenser and to thereby further augment operation of said first means.
Claim 5
Dependent Claim 50 words
The invention as defined in claim 3 wherein third temperature responsive means is adapted to energize said pump means to cause water to be delivered to said evaporative cooler pad and to thereby cause said evaporative cooler to deliver evaporatively cooled air toward said condenser to further augment operation thereof.
Claim 6
Dependent Claim 54 words
The invention as defined in claim 1 wherein temperature responsive means is adapted to respond to a temperature above said design temperature; said temperature responsive means coupled to and adapted to energize said evaporative cooler type air conditioner for delivering evaporative cooled air to said inlet of said condenser for augmenting the operation thereof.
Claim 7
Dependent Claim 75 words
A combination air conditioner comprising an air-to-air refrigeration unit having a condenser communicating with ambient outside atmosphere; means for moving air through said condenser; and an evaporative cooler spaced from said condenser and adapted to deliver evaporatively cooled air to said condenser; said evaporative cooler spaced from said condenser a sufficient distance so as not substantially to interfere with normal outside ambient air flow through said condenser in accordance with the operation of said means.
Claim 8
Dependent Claim 75 words
A combination air conditioner comprising an air-to-air refrigeration unit having a condenser communicating with ambient outside atmosphere; means for moving air through said condenser; and an evaporative cooler spaced from said condenser and adapted to deliver evaporatively cooled air to said condenser; said evaporative cooler spaced from said condenser a sufficient distance so as not substantially to interfere with normal outside ambient air flow through said condenser in accordance with the operation of said means.
Claim 9
Dependent Claim 81 words
A combination air conditioner comprising an air-to-air refrigeration unit having a condenser communicating with outside atmosphere; means for moving air through said condenser; and an evaporative cooler spaced from said condenser and adapted to deliver air to augment air flow moved through said condenser by said means; said evaporative cooler spaced from said condenser a sufficient distance so as not to substantially interfere with normal flow of outside ambient atmosphere through said condenser in accordance with the operation of said means.
Claim 10
Dependent Claim 81 words
A combination air conditioner comprising an air-to-air refrigeration unit having a condenser communicating with outside atmosphere; means for moving air through said condenser; and an evaporative cooler spaced from said condenser and adapted to deliver air to augment air flow moved through said condenser by said means; said evaporative cooler spaced from said condenser a sufficient distance so as not to substantially interfere with normal flow of outside ambient atmosphere through said condenser in accordance with the operation of said means.
