Claim 1

Independent Claim 170 words

Method for air conditioning a region in a building where the building utilizes construction elements of concrete or the like having channels therein through which air is passed between the outside environment and said region, comprising passing air from said region through the channels of said elements from said region to the outside environment for a first predetermined period of time to thereby transfer the temperature condition of the air leaving the region to said construction elements, reversing the flow by passing said air from the outside environment through said channels to said region for a second predetermined period of time to thereby transfer the temperature condition of the construction elements to said air entering said region, alternating said flows for said first and second periods of time regularly substantially continuously, and regulating said flows and said first and second periods of time to control the temperature in said region and to simultaneously balance the air pressure in said region, so that said construction elements function as regenerative heat exchangers.

Claim 3

Dependent Claim 65 words

Method according to claim 1 wherein said construction elements form at least two of the walls of the building, and further comprising dividing said flow of air so that when air is passed from the outside into said region through the channels of one wall, air is simultaneously passed from said region through and out of the channels of a second wall to the outside.

Claim 4

Dependent Claim 98 words

Method according to claim 1, wherein said construction elements form a floor type frame-work, and further comprising, dividing said flow of air so that when air is passed from the interior of said region through the channels of a certain part of the frame-work, to the outside environment air is simultaneously passed from the outside environment through the channels of a second part of said framework, to said region, and controlling the division of the flow so that said second part of the framework traversed by the flow is substantially equal to said first part of the framework.

Claim 5

Dependent Claim 57 words

Method according to any one of claims 1, 2 or 3, and further comprising interrupting said substantially continuous alternating flows for a relatively sort period of time and passing air from the outside environment through said channels only and return to the outside enironment in order to clean the channels from dirt during said period of interruption.

Claim 6

Dependent Claim 55 words

Method according to any one of the claims, 1, 2 or 3, and further comprising passing air through the channels from the outside environment directly to be mixed with the air passing through the channels, and mixing this outside air with the air passing through the channels before this air is passed into the region.

Claim 7

Dependent Claim 38 words

Method according to claim 3, and further comprising providing a covering layer spaced from said framework to form a narrow space therebetween, and passing said air through said narrow space in series with said flow through said channels.

Claim 8

Dependent Claim 209 words

An arrangement for air conditioning a region within a building where the building utilizes construction elements of concrete or the like having channels wherein through which air is passed comprising, a first group of channels in said construction elements, means to connect said first group of channels to the outside environment, a second group of channels at a different location in said construction elements, second means to connect said second group of channels to the outside environment, at least one exhaust duct for said region adapted to be alternately communicated with said first group of channels and said second group of channels, at least one inlet duct for said region adapted to be alternately communicated with said first group of channels and said second group of channels, pump means to force said air through said ducts and channels, and valve means operably connected to said exhaust and inlet ducts and to said first and second groups of channels to connect said exhaust duct alternately with said first and second groups of channels while simultaneously connecting said inlet duct alternately with said second and first group of channels to control the flow of air reversibly through said first and second groups of channels between said ducts and the outside environment.

Claim 9

Dependent Claim 209 words

An arrangement for air conditioning a region within a building where the building utilizes construction elements of concrete or the like having channels wherein through which air is passed comprising, a first group of channels in said construction elements, means to connect said first group of channels to the outside environment, a second group of channels at a different location in said construction elements, second means to connect said second group of channels to the outside environment, at least one exhaust duct for said region adapted to be alternately communicated with said first group of channels and said second group of channels, at least one inlet duct for said region adapted to be alternately communicated with said first group of channels and said second group of channels, pump means to force said air through said ducts and channels, and valve means operably connected to said exhaust and inlet ducts and to said first and second groups of channels to connect said exhaust duct alternately with said first and second groups of channels while simultaneously connecting said inlet duct alternately with said second and first group of channels to control the flow of air reversibly through said first and second groups of channels between said ducts and the outside environment.

Claim 10

Dependent Claim 61 words

An arrangement as claimed in claim 7 wherein said pump means comprises a first fan in said exhaust duct between said region and said valve means and a second fan in said inlet duct between said region and said valve means, and regulation means operably connected with said valve means and said region to balance the air pressure within said region.

Claim 11

Dependent Claim 26 words

Arrangement according to claim 8 wherein said regulation means includes a timer for controlling the valve means to reverse flow through said channels at predetermined intervals.

Claim 12

Dependent Claim 104 words

Arrangement according to claim 8 wherein said valve means comprises a four-way valve having a valve housing, four ports, and a driven valve body, each one of said exhaust and inlet ducts being connected to a respective one of said ports and each of said two groups of channels being connected to a respective one of the remaining ports, and means to drive said valve body intermittently to alternately connect the port of said exhaust duct with the port of said first group of channels and the port of said inlet duct with the port of said second group of channels and vice versa.

Claim 13

Dependent Claim 56 words

Arrangement according to claim 10 wherein said valve body in an intermediate position between said alternate connecting positions closes said ports to said channels, and further comprising a fist outside inlet connected to the inlet of said second fan, and a damper valve in said first outside inlet to control the flow of outside air therethrough.
