System for climate-control of interior spaces of a building

2:

• The system according to claim 1,
• wherein the heat recovery device (103) is designed to provide heated fresh air (53) for the circulating air module (5).

3:

• The system according to claim 1,
• wherein the heat recovery device (103) is designed to heat water and provide it the water as hot water.

4:

• The system according to claim 1,
• wherein the heat recovery device (103) comprises the climate-control device (107) so that the recovered heat is used for air-conditioning the interior spaces (2).

5:

• The system according to claim 1,
• wherein the heat recovery device (103) is designed as a heat pump (111).

6:

• The system according to claim 1,
• wherein the heat recovery device (103) is designed to recover thermal energy also from waste water and/or outside air.

7:

• The system according to claim 1,
• wherein the circulating air module (5) is designed so that the fresh air (53) can be sucked through the heat exchanger (43) and mixes with the circulating air (55) in the heat exchanger (43) and/or inside air fan (49).

8:

• The system according to claim 7,
• wherein the inside air fan is a radial inside air fan (49) with an axially arranged air inlet facing the heat exchanger (43), and the radial inside air fan (49) is one of a plurality of radial inside air fans (49), which are arranged laterally next to one another between a front side (15) and a rear side (17) of the housing (13), particularly offset from one another along a longitudinal direction, so that the axially arranged air inlets of the radial inside air fans (49) face the heat exchanger (43).

9:

• The system according to claim 8,
• wherein a plane extends through the radial inside air fans (49) so that their axially arranged air inlets point away from the same side of the plane,
• and wherein the radial inside air fans (49) each have an axis of rotation and wherein the axes of rotation extend perpendicularly or substantially perpendicularly to the plane and/or the axes of rotation extend parallel or substantially parallel to one another.

10:

• The system according to claim 1,
• wherein the circulating air module (5) comprises a flow channel (51) designed to guide the fresh air (53) to the heat exchanger (43).

11:

• The system according to claim 10,
• wherein the flow duct (51) extends between the heat exchanger (43), through which the fresh air (53) can be drawn with the inside air radial fan(s) (49), and a longitudinal side (19, 21) of the housing (13).

12:

• The system according to claim 1,
• wherein the circulating air module (5) comprises a fresh air fan (47) arranged in the housing (13) and supplying the fresh air (53), which is arranged between the front (15) and the rear (17) of the housing (13) laterally next to the radial inside air fan or fans (49), or wherein a fresh air fan (47) supplying fresh air (53) through the fresh air inlet (39) is arranged outside the housing (13).

13:

• The system according to claim 1,
• wherein the radial inside air fan or fans (49) in the circulating air module (5) are modularly designed.

14:

• The system according to claim 1, comprising a mounting frame (11) into which the circulating air module (5) can be inserted and which can be installed in a ceiling area (83) or attached to a ceiling or which can be inserted into a building wall (1) of an interior space or attached to the building wall (1) of the interior space.

15:

• The system according to claim 14, wherein the mounting frame (11) or the fresh air inlet (39) of the circulating air module (5) can be coupled to a fresh air duct (85), via which fresh air (53) can be guided to the circulating air module (5).
