Abstract
Abstract An installation for conditioning air in an associated space, comprising at least two pairs of heat exchangers, each such pair including a surface heat exchangers and a mixing one, the second (in the direction of the flow of the air being treated through the apparatus) pair of heat exchangers communicating through the surface heat exchanger of the first pair with the conduit through which ambient air to be treated by the apparatus is supplied, for this air, after its having been cooled in the last-mentioned heat exchanger, to be directed for still deeper cooling into the surface heat exchanger and the mixing heat exchanger of the second pair.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
An installation for conditioning air in an associated space comprising: a main surface heat exchanger having an air path and an air inlet conduit through which air to be conditioned is supplied into said air path; a main mixing heat exchanger wherein air is used for cooling liquid serving as the intermediate coolant in said main surface heat exchanger; at least one auxiliary surface heat exchanger and at least one auxiliary mixing heat exchanger having the respective air paths thereof communicating through said air path of said main surface heat exchanger with said air inlet conduit of said air path of said main surface heat exchanger, whereby the air supplied into said at least one auxiliary surface heat exchanger and into said at least one auxiliary mixing heat changer is the air pre-cooled within said main surface heat exchanger; the liquid coolant path of said at least one auxiliary mixing heat exchanger being connected through liquid coolant conduit means with the liquid coolant path of said at least one auxiliary surface heat exchanger, said respective air paths of said main mixing heat exchanger and of said at least one auxiliary mixing heat exchanger communicating through air conduit means.
Claim 2
Dependent Claim
198 words
An installation for conditioning air in an associated space comprising: a main surface heat exchanger having an air path and an air inlet conduit through which air to be conditioned is supplied into said air path; a main mixing heat exchanger wherein air is used for cooling liquid serving as the intermediate coolant in said main surface heat exchanger; at least one auxiliary surface heat exchanger and at least one auxiliary mixing heat exchanger having the respective air paths thereof communicating through said air path of said main surface heat exchanger with said air inlet conduit of said air path of said main surface heat exchanger, whereby the air supplied into said at least one auxiliary surface heat exchanger and into said at least one auxiliary mixing heat changer is the air pre-cooled within said main surface heat exchanger; the liquid coolant path of said at least one auxiliary mixing heat exchanger being connected through liquid coolant conduit means with the liquid coolant path of said at least one auxiliary surface heat exchanger, said respective air paths of said main mixing heat exchanger and of said at least one auxiliary mixing heat exchanger communicating through air conduit means.
Claim 3
Dependent Claim
72 words
An installation as claimed in claim 1, wherein said main surface heat exchanger includes two sections, the air path of one of said two sections communicating with said air path of said auxiliary surfAce heat exchanger, the air path of the other one of said two sections communicating with said air path of said auxiliary mixing heat exchanger, the respective liquid coolant paths of said two sections being connected to each other.
Claim 4
Dependent Claim
71 words
An installation as claimed in claim 1, wherein the air outlet conduit of said air path of said auxiliary mixing heat exchanger communicates with the outlet air conduit of said air path of said main mixing heat exchanger, said air inlet conduit of said air path of said main mixing heat exchanger being connected to a conduit communicating with said space associated with said air conditioning apparatus for withdrawing air therefrom.
Claim 5
Dependent Claim
38 words
An installation as claimed in claim 1, wherein said air inlet conduit of said air path of said main mixing heat exchanger communicates with the air outlet conduit of said air path of said auxiliary mixing heat exchanger.
Claim 6
Dependent Claim
64 words
An installation as claimed in claim 1 wherein said air conduit establishing communication between the respective air paths of said auxiliary mixing heat exchanger and of said main mixing heat exchanger, through which air flows from said auxiliary mixing heat exchanger into said main mixing heat exchanger, communicates with a conduit communicating with said space associated with said air-conditioning installation, for withdrawing air therefrom.
Claim 7
Dependent Claim
58 words
An installation as claimed in claim 2, wherein said air inlet conduit of said air path of said other one section of said main surface heat exchanger, which communicates with said air path of said auxiliary mixing heat exchanger, is connected to a conduit communicating with said space associated with said air conditioning installation, for withdrawing air therefrom.
