Abstract
Abstract A cooling tower system which comprises a dry cooling tower, according to which normally the medium to be cooled is passed through a dry cooling tower cooled by atmospheric air, and in which in response to said atmospheric air exceeding a certain temperature, a portion of the cooling medium to be cooled is conveyed to a water-cooled tower to be cooled thereby.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A cooling tower system, which includes: first main heat exchanger means provided with means for passing therethrough a medium to be cooled, first conduit means for conveying the medium to be cooled to said first heat exchanger means, said first heat exchanger means also including means to be engaged by atmospheric air for effecting a heat exchange between said atmospheric air and the medium to be cooled, second direct parallel connected heat exchanger means provided with means for passing therethrough a medium to be cooled, said second heat exchanger means also including means to be engaged by water for effecting a heat exchange between said water and the medium to be cooled, and second conduit means leading to and communicating with said second heat exchanger means for conveying at least a branch portion of the medium to be cooled to said second heat exchanger means.
Claim 2
Dependent Claim
145 words
A cooling tower system, which includes: first main heat exchanger means provided with means for passing therethrough a medium to be cooled, first conduit means for conveying the medium to be cooled to said first heat exchanger means, said first heat exchanger means also including means to be engaged by atmospheric air for effecting a heat exchange between said atmospheric air and the medium to be cooled, second direct parallel connected heat exchanger means provided with means for passing therethrough a medium to be cooled, said second heat exchanger means also including means to be engaged by water for effecting a heat exchange between said water and the medium to be cooled, and second conduit means leading to and communicating with said second heat exchanger means for conveying at least a branch portion of the medium to be cooled to said second heat exchanger means.
Claim 3
Dependent Claim
31 words
A cooling tower system according to claim 1, in which said second conduit means branches off said first conduit means prior to the latter reaching said first main heat exchanger means.
Claim 4
Dependent Claim
49 words
A cooling tower system according to claim 1, in which said first conduit means and said first main heat exchanger means and said second conduit means and said second direct heat exchanger means follow each other in this sequence and are arranged in series with regard to each other.
Claim 5
Dependent Claim
38 words
A cooling tower system according to claim 1, in which said second conduit means includes a steam pipe, and in which said second direct heat exchanger means includes a water cooled condenser and a water cooled wet cooler.
Claim 6
Dependent Claim
31 words
A cooling tower system according to claim 4, which includes fluid circuit means comprising circulating pump means for circulating the water of said wet cooler for cooling said water cooled condenser.
Claim 7
Dependent Claim
29 words
A cooling tower system according to claim 5, in which said wet cooler and said water cooled condenser are located in front of said first main heat exchanger means.
Claim 8
Dependent Claim
43 words
A cooling tower system according to claim 1, in which said second conduit means includes a steam pipe leading to said second direct heat exchanger, and valve means is interposed in said steam pipe and is adapted selectively to be opened and closed.
Claim 9
Dependent Claim
30 words
A cooling tower system according to claim 4, which includes auxiliary cooling means associated with said water cooled wet cooler and operable to control cooling air for said wet cooler.
Claim 10
Dependent Claim
93 words
A cooling water system according to claim 7, in which said valve means is pressure responsive and operable in response to a set pressure for the medium to be cooled to open for conveying a portion of the medium to be cooled to said second direct heat exchanger means, hydraulic circuit means including a circulating pump associated with said second direct heat exchanger means and operatively connected to said valve means so as in response to the opening of said valve means to circulate cooling fluid through said second direct heat exchanger means.
