Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
A facade element for installing on an exterior wall of a building, for carrying out the process of using heat exchangers for the exchange of heat between flows of a medium streaming in and out of a building, wherein the flows of the medium after passing through a passive heat exchanger are directed to a heat pump and each one of the flows passes through the appropriate warm, or cold, heat exchangers of the heat pump, comprising the following characteristics, an insulated exterior wall and an interior wall, a medium partition, whereby exterior wall and medium partition form, on the intake side, a flow channel which connects to the floor of the building below the facade element and draws spent air out of that floor, and the interior wall and the medium partition form on the outlet side, flow channel for fresh air which channel connects to the upper floor served by the facade element, and a heat pump thermodynamically coupled to the channels.
Claim 2
Dependent Claim
164 words
A facade element for installing on an exterior wall of a building, for carrying out the process of using heat exchangers for the exchange of heat between flows of a medium streaming in and out of a building, wherein the flows of the medium after passing through a passive heat exchanger are directed to a heat pump and each one of the flows passes through the appropriate warm, or cold, heat exchangers of the heat pump, comprising the following characteristics, an insulated exterior wall and an interior wall, a medium partition, whereby exterior wall and medium partition form, on the intake side, a flow channel which connects to the floor of the building below the facade element and draws spent air out of that floor, and the interior wall and the medium partition form on the outlet side, flow channel for fresh air which channel connects to the upper floor served by the facade element, and a heat pump thermodynamically coupled to the channels.
Claim 3
Dependent Claim
12 words
The facade element of claim 1 and equipped with a heat-conducting partition.
Claim 4
Dependent Claim
48 words
The facade element of claim 1 with the characteristics that the flow channels ending at the area of the lower edge of a window extend substantially the entire width of the facade element and that the outlets for fresh air and spent air are equipped with slotted vents.
Claim 5
Dependent Claim
48 words
A facade element in accordance with claim 1 with the characteristic that a fan is installed in the area of the inlets for fresh air and spent air in such a way that the fan moves on the one side fresh air and on the other spent air.
Claim 6
Dependent Claim
61 words
A facade element of claim 1 with the characteristic that a fire safety valve having half-cylinder form is placed inside the spent air channel in the area of the fan and heat-sensitive materials hold the valve, so that when heat-sensitive materials are destroyed, the safety valve falls into its closed position of its own weight and/or with the assistance of springs.
Claim 7
Dependent Claim
25 words
The facade element of claim 1 with the characteristic that the medium partition is insulated and is insulated in the area of the heat pump.
Claim 8
Dependent Claim
47 words
The facade element of claim 1 with the characteristic that the front part of the element is inclined in relation to the vertical so that a shaft for electrical installation is formed between the insulated interior wall of the element and the outer wall of the building.
Claim 9
Dependent Claim
39 words
The facade element in accordance with claim 7 with the characteristic that solar energy collectors, thermodynamically integrated in the heating and air-conditioning system of the facade element, are installed on the front of the exterior wall of said element.
Claim 10
Dependent Claim
28 words
The facade element in accordance with claim 8, with the characteristic that a balcony-like structure is equipped with a transparent floor below which solar energy collectors are installed.
