Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
A method of evaporative cooling for use with an evaporative cooler consisting of a cooling tower including a multi-layer contact body having gaps between the layers in which the formation of mist by condensation of vapor on return of the cooling air to the atmosphere is avoided; said method comprising the steps of supplying warm water to be cooled to a first group of the gaps in the contact body while supplying cooling air to substantially all of the gaps in the cooling body whereby the temperature and moisture content of air supplied to the gaps to which warm water is supplied are increased while the temperature of the air supplied to the other gaps is increased by heat transfer through adjacent layers of the contact body without substantially changing the moisture content thereof; and then mixing the warmed air from said first group of gaps with air from gaps to which only air was supplied before discharging the air to the atmosphere.
Claim 2
Independent Claim
163 words
A method of evaporative cooling for use with an evaporative cooler consisting of a cooling tower including a multi-layer contact body having gaps between the layers in which the formation of mist by condensation of vapor on return of the cooling air to the atmosphere is avoided; said method comprising the steps of supplying warm water to be cooled to a first group of the gaps in the contact body while supplying cooling air to substantially all of the gaps in the cooling body whereby the temperature and moisture content of air supplied to the gaps to which warm water is supplied are increased while the temperature of the air supplied to the other gaps is increased by heat transfer through adjacent layers of the contact body without substantially changing the moisture content thereof; and then mixing the warmed air from said first group of gaps with air from gaps to which only air was supplied before discharging the air to the atmosphere.
Claim 3
Dependent Claim
34 words
The method as defined in claim 1 including the step of controlling the number of gaps to which the warm water is supplied in accordance with the temperature of the air in the atmosphere.
Claim 4
Dependent Claim
59 words
The method as defined in claim 1 wherein said step of supplying warm water to some of the gaps in the cooling body comprises the step of supplying said warm water to alternate gaps whereby cooling air flowing in the gaps therebetween is heated by conduction through the adjacent contact body layers without a substantial change in moisture content.
Claim 5
Dependent Claim
138 words
An evaporative cooling device comprising a casing having cooling air inlet and outlet openings formed therein; a contact body positioned in said casing and formed from a plurality of contact layers defining a plurality of water and air flow gaps therebetween providing communication between said air inlet and outlet openings; means positioned above said contact body for supplying warm water to be cooled to only some of said gaps; and means for supplying cooling air from said inlet opening through substantially all of said gaps to said outlet opening, whereby the temperature and moisture content of air supplied to the gaps to which warm water is supplied are increased while the temperature of air supplied to the other gaps is increased by heat transfer through adjacent layers of the contact body without substantially changing the moisture content thereof.
Claim 6
Dependent Claim
138 words
An evaporative cooling device comprising a casing having cooling air inlet and outlet openings formed therein; a contact body positioned in said casing and formed from a plurality of contact layers defining a plurality of water and air flow gaps therebetween providing communication between said air inlet and outlet openings; means positioned above said contact body for supplying warm water to be cooled to only some of said gaps; and means for supplying cooling air from said inlet opening through substantially all of said gaps to said outlet opening, whereby the temperature and moisture content of air supplied to the gaps to which warm water is supplied are increased while the temperature of air supplied to the other gaps is increased by heat transfer through adjacent layers of the contact body without substantially changing the moisture content thereof.
Claim 7
Dependent Claim
91 words
The device as defined in claim 4 wherein said gaps are formed between adjacent layers of the contact body and said layers have upper inlet wall portions between which the warm water is supplied; said means for supplying the warm water supplying the water to selectively spaced gaps such that the gaps having no water therein are adjacent to at least one gap having warm water flowing therethrough whereby cooling air flowing therein is heated by conduction through the contact body separating the gaps without a substantial change in moisture content.
Claim 8
Dependent Claim
48 words
The device as defined in claim 5 wherein said means for supplying warm water to said gaps comprises at least two groups of pipe channels disposed above the gaps of the contact body with the channels of one group being located between the channels of the other group.
Claim 9
Dependent Claim
22 words
The device as defined in claim 6 wherein each channel group is connected to a separate distributor duct for the warm water.
