Definitions

• the present invention relates to a heat recovery system com ⁇ prising a regenerative heat exchanger in which the air leaving a room space yields its heat to a battery, which in turn yields its heat to air entering from the outside.
• the heat recovery system according to the invention is characterized in that the air which enters via the heat exchanger is directed into the space between two or more window panes, from where it is fur ⁇ ther directed into the room space. All experiments and measure ⁇ ments have shown that the efficiency achieved with a heat re ⁇ covery system of this type is very high, up to 85-90 %. Warm windows are also achieved by means of the invention. Room- specific ventilation in compliance with the standards is ob ⁇ tained. The acquisition costs of the entire heat recovery sys ⁇ tem are also very low.
• One embodiment of the invention is characterized in that the air entering the regenerative heat exchanger can be heated or cooled, depending on the conditions, by means of a second heat exchanger linked to the system.
• a second heat exchanger linked to the system.
• Another embodiment of the invention is characterized in that one heat exchanger is coupled both to a heating device and a to a cooler so that it will be possible, by means of valves, to feed into the heat exchanger a liquid at 8-80 °C.
• a system of this kind is easy to automate, in which case the temperature and ventilation of the room space are continuously as predeter ⁇ mined and desired.
• Figure 1 depicts the heat recovery system connected to a win ⁇ dow
• Figure 2 depicts the control system of a regenerative heat exchanger
• Figure 3 depicts a heat recovery system to which there are coupled both a heating device and a cooling device.
• the heat recovery system comprises a regenerative heat ex ⁇ changer 1, in which the air 2 leaving the room space yields its heat to a battery 3, 4, which in turn yields its heat to the air 5 entering from the outside.
• the air entering via the heat exchanger 3, 4 is directed into the space between two window panes 6, 7, from where it is further directed via a slit 8 into the room space.
• Figure 2 shows how the air coming continuously from the room space flows as indicated by the arrow 2, and by means of a baffle 9 it is directed alternately to batteries 3, 4.
• the batteries 3, 4 are heated alternately, and the incoming air 5 is heated alternately in the batteries 3, 4 and is then directed by the baffle 9, in the manner indicated by the arrow 10, into the space between the window panes 6, 7.
• FIG. 3 depicts an embodiment in which there is coupled to the system a second heat exchanger 11, in which the incoming air can be either heated or cooled, depending on the conditions.
• the heat exchanger 11 is coupled both to a heating device 12 and to a cooler 13 so that by means of valves 14, 15 a liquid at 8-80 °C can be fed to the heat exchanger 11.
• An energy balance under experimental conditions in which a second heat exchanger was not used is shown below.
• the measurements were made according to an outside temperature of -4 °C.
• the air change was 18 m 3 /h.
• the window (double- glazed) was 120 x 120 cm.
