DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Exemplary embodiments of the present invention are explained in detail below with reference to the accompanying drawings. The present invention is not limited to the embodiments.
Fig. 1 is a perspective view of a heat exchanging ventilator according to a first embodiment of the present invention; Fig. 2 is a perspective plan view thereof; Fig. 3 is a perspective side view thereof; Fig. 4 is a block diagram of a controlling device of a fan; and Fig. 5 is a table containing operation modes of fans for different conditions of outside temperature and inside/outside humidity.
As shown in Figs. 1 to 3, a heat exchanging ventilator 100 includes a heat exchanger 1 that facilitates heat exchange between inside air with outside air. The heat exchanger 1 is installed in a main body casing 2, which is like a rectangular box. The heat exchanging ventilator 100 ventilates a room by simultaneously supplying and exhausting air while performing heat exchange.
In the heat exchanging ventilator 100 are formed an air-supply path 4 and an air-exhaust path 6. On the air-supply path 4, air drawn in by an air supplying fan 5 from
1713633-1 7

an outside-air inlet 26 passes through an air-supply passage la (see Fig. 3) of the heat exchanger 1, and is supplied inside a room from an inside-air outlet 27. On the other hand, on the air-exhaust path 6, air inside the room drawn in by an air exhausting fan 3 from an inside-air inlet 24 passes through an air-exhaust passage lb (see Fig. 3) of the heat exchanger 1, and is exhausted from an outside-air outlet 25.
The air-supply path 4 and the air-exhaust path 6 are formed in the heat exchanger 1 by assembling the heat exchanger 1, the air supplying fan 5, and the air exhausting fan 3 in the main body casing 2 at appropriate locations, and then installing an air-supply-path portion 12 and an air-exhaust-path portion 11.
The air-supply path 4 is formed as a ventilation flue and extends between the outside-air inlet 2 6 and the inside-air outlet 27. The outside-air inlet 26 is an opening on the main body casing 2 corresponding to an inlet portion 15 of the air-exhaust-path portion 11 while the inside-air outlet 27 is an opening on the main body casing 2 corresponding to an outlet portion 14 of the air-supply-path portion 12. Specifically, from the inlet portion 15, the air-supply path 4 passes through the air-supply passage la of the heat exchanger 1 from the upper side of the heat exchanger 1, and reaches the outlet portion 14 via the air

supplying fan 5,
On the other hand, the air-exhaust path 6 is formed as a ventilation flue that extends from the inside-air inlet 24 to the outside-air outlet 25. The inside-air inlet 24 is an opening on the main body casing 2 corresponding to the inlet portion 15 of the air-supply-path portion 12 while the outside-air outlet 25 is an opening on the main body casing 2 corresponding to the outlet portion 14 of the air-exhaust-path portion 11.Specifically, from the inlet portion 15, the air-supply path 6 passes through the air-exhaust passage lb of the heat exchanger! from the upper side of the heat exchanger 1, and reaches the outlet portion 14 via the air supplying fan 3.
A bypass air-supply path 10 is formed as an air ventilation flue for supplying outside air to the inside-air outlet 27 from the outlet portion 14 of the air-supply-path portion 12 after detouring the heat exchanger 1, prior to which the air, drawn in due to opening of a bypass damper 9, is let in from the outside-air inlet 26, and passes through the inlet portion 15 of the air-supply-path portion 12,
A bypass air exhaust, although not shown in the diagram, can be formed as an air ventilation flue for exhausting air inside the room to the outside-air outlet 25 from the outlet portion 14 of the air-exhaust-path portion
11 after detouring the heat exchanger 1, prior to which the air, drawn in due to opening of a bypass damper, can be let in from the inside-air inlet 24 and can pass through the inlet portion 15 of the air-supply-path portion 12.
A cylindrical member 16 for connecting a duct is attached to the outside-air inlet 26 and the inside-air outlet 27 of the air-supply path 4, and the inside-air inlet 24 and the outside-air outlet 25 of the air-exhaust path 6.
The heat exchanging ventilator 100 supplies fresh air to the room. The fresh air being the outside air that has flown along the air-supply path 4 and passed through the heat exchanger 1. Moreover, the heat exchanging ventilator 100 exhausts air inside the room. The air being the air present inside the room and that has flown along the air-exhaust path 6 and passed through the heat exchanger 1. In addition, the heat exchanging ventilator 100 facilitates heat exchange ventilation while supplying and exhausting of the air is being simultaneously performed.
When the bypass air-supply path 10 or the bypass air-exhaust path is opened, with the help of a damper, outside air can be supplied to the room or the air inside the room can be exhausted to the outside without passing through the heat exchanger 1 because of the actions of the air supplying fan 5 and the air exhausting fan 3. In this case,
the heat exchanging ventilator 100 as an ordinary ventilator that does not perform the heat exchange.
A fan casing 13 of the air-exhaust-path portion 11 and the outlet portion 14 communicate to form an air-exhaust path. The outlet portion 14 has openings in two directions: one in a direction of the air flow from the fan casing 13 and another in a perpendicular direction to the direction of the air flow from the fan casing 13. As shown in Fig. 2, a damper board 7 is arranged in a bifurcated portion of the outlet portion 14 so that exhaust-path opening areas can be adjusted for the openings in both the directions of the outside-air outlet 25 of the air-exhaust path 6.
When the damper board 7 rotates around an axis of the damper, which is not shown in the diagram, an opening of the exhaust-path opening area in one direction, out of the two directions of the outside-air outlet 25 of the air-exhaust path 6, is reduced in size while the exhaust-path opening area in another direction is expanded.
The fan casing 13 of the air-supply-path portion 12 and the outlet portion 14 communicate to form an air-exhaust path. The outlet portion 14 has openings in two directions, one in a direction of the air flow from the fan casing 13 and another in a perpendicular direction to the direction of the air flow from the fan casing 13. As shown
in Fig. 2, a damper board 8 is arranged in a bifurcated portion of the outlet portion 14 so that exhaust-path opening areas can be adjusted for the openings in both the directions of the inside-air outlet 27 of the air-supply path 4.
When the damper board 8 rotates around an axis of the damper, which is not shown in the diagram, an opening of the exhaust-path opening area in one direction, out of the two directions of the inside-air outlet 27 of the air-supply path 4., is reduced in size while the exhaust-path opening area in another direction is expanded.
The heat exchanging ventilator 100 includes a temperature sensor 19a and a humidity sensor 19b corresponding to the outside-air outlet 25, an outside-temperature sensor 19c and an outside-humidity sensor 19d corresponding to the outside-air inlet 26, and an inside-temperature sensor 20a and an inside-humidity sensor 20b corresponding to the inside-air inlet 24. Moreover, the heat exchanging ventilator 100 includes a temperature sensor 20c for sensing the temperature of the air blown into the room and a humidity sensor 20d for sensing the humidity of the air blown into the room corresponding to the inside-air outlet 27.
These sensors detect temperatures and relative humidities of airs inside and outside the room. The
12
absolute humidities of airs inside and outside the room are calculated to understand the absolute humidities of the airs inside and outside the room. For example, when the absolute humidity of the outside air that is being taken in is lower than the absolute humidity of the inside air, operation of the heat exchanging ventilator 100 is controlled so as to increase the volume of ventilation air. On the contrary, when the absolute humidity of the air that is being blown into the room is lower than the absolute humidity of the inside air, operation of the heat exchanging ventilator 100 is controlled so as to increase the volume of ventilation air.
As shown in Fig. 4, in a controlling device 200 of the fan, temperature signals indicative of temperatures and humidity signals indicative of relative humidities of the outside air (or of the air blown into the room) and the inside air detected with the temperature sensors 19c (or 20c) and 20a, and the humidity sensors 19d (or 20d) and 20b, are output to a calculating unit 34. The calculating unit 34 calculates absolute humidities of the outside air (or the absolute humidity of the air blown into the room) and the inside air based on the temperature signals and the relative humidity signals by employing a saturated water vapor curve.
The calculating unit 34 outputs the calculated
13
absolute humidities of the outside air (or the air blown into the room) and the inside air to an air volume setting unit 35. The air volume setting unit 35 sets volumes of airs to be supplied to the room or exhausted from the room by the fans 3 and 5 based on a table for setting operation mode of the fans shown in Fig. 5. The table includes operation modes corresponding to magnitudes of the absolute humidities of the outside air (or the air blown into the room) and the inside air. The calculating unit 34 informs the set volumes of airs to a motor driving device 31. The motor driving device 31 controls the volumes of airs of the fans 3 and 5 by controlling motors 22 and 23 of the fans 3 and 5. The controlling device 200 includes the calculating unit 34 and the air volume setting unit 35. Controlling air volume using the temperature and the relative humidity of the air blown into the room is more accurate than controlling air volume using the temperature and the relative humidity of the outside air.
As shown in Fig. 5, the temperature of the outside air or the temperature of the air blown into the room (temperature of air supplied (SA) to the room; hereinafter, "SA temperature") in a period of severe cold in winter is less than 5°C, in a period of normal temperature in winter is equal to or more than 5°C but less than 10°C, in a period in between summer and autumn is equal to or more
than 10°C but less than 18°C, and in a period of summer is equal to or more than 18°C.
During the period of severe cold in winter, when the SA temperature is less than 5°C, because residents feel cold, air supply is stopped or the volume of air is set to equal to or less than 20% of the air blowing capacity. During the period of normal temperature in winter, when the absolute humidity of the SA is lower than the absolute humidity of the air inside the room ra, the heat exchange ventilation or the bypass ventilation without the heat exchange is performed at 40% to 60% of the air blowing capacity, with the purpose of dehumidifying the room.
However, during the period of normal temperature in winter, when the absolute humidity of the SA is higher than the absolute humidity of the air inside the room ElA, ventilation is not implemented proactively. The volume of air is set to equal to or less than 20% of the air blowing capacity mentioned earlier, and while ensuring minimum required volume of ventilation air, care is taken so as not to increase the humidity in the room.
During the period in between summer and autumn, when the absolute humidity of the air inside the room RA is higher than the absolute humidity of the SA, strong blows of air of 60% to 100% of the air blowing capacity are blown so as to proactively reduce the humidity inside the room.
On the contrary, when the absolute humidity of the SA is lower than the absolute humidity of the air inside the room ElA., the volume of air is switched to equal to or less than 20% of the air blowing capacity mentioned earlier, and care is taken so as not to increase the humidity in the room.
During the period of summer, the absolute humidity of the SA is higher as compared to the absolute humidity of the air inside the room RA, which is reduced by an air conditioner. Therefore, the volume of air is set to equal to or less than 20% of the air blowing capacity mentioned earlier, and while ensuring minimum required volume of ventilation air, care is taken so as not to increase the humidity in the room.
Fig. 6 is a perspective view of a heat exchanging ventilator according to a second embodiment of the present invention. Fig. 7 is a perspective plan view of the heat exchanging ventilator according to the second embodiment.
As shown in Figs. 6 and 7, a heat exchanging ventilator 300 according to the second embodiment includes two heat exchangers 43. The heat exchangers 43 are arranged parallel to each other, in substantially a V shape, in a substantially central part of a main body casing 38, which is like a rectangular box. The heat exchangers 43 perform heat exchange by supplying and exhausting the air simultaneously, thus ventilating the air inside the room.
The heat exchanging ventilator 300 includes an air-supply path (shown with dotted lines in Fig. 7; partition wall of the air supplying path is not shown) and an air-exhaust path. The air supplying path supplies outside air drawn in by an air supplying fan 44, which is located on the left side in the main body casing 38, inside the room by , from an outside-air inlet 39, located on the right side of the main body casing 38, The air passes through an air supplying passage of air-supply filters 42, 42 and the heat exchangers 43, 43, and the air is supplied through an inside-air outlet 37 arranged in a detachable, small inside casing 45 on the main body casing 38. The air-exhaust path (shown with continuous lines in Fig. 7; partition wall of the air-exhaust path is not shown) is for drawing in air inside the room by an air exhausting fan 41, located on the right side in the main body casing 38, from an inside-air inlet 40 located in the inside casing 45, passing the air through an air-exhaust passage of the heat exchangers 43, 43, and exhausting the outside air inside the room from an outside-air outlet 36, located on the right side of the main body casing 38.
The inside-air inlet 40 and the inside-air outlet 37 are arranged in the inside casing 45, and the air supplying and the air-exhaust path is formed inside the inside casing 45, as mentioned above. A bypass-air supplying path or a
bypass air-exhaust path, not shown in the diagram, can be arranged in the main body casing 38, as in the case of the heat exchanging ventilator 100 of the first embodiment.
The heat exchanging ventilator 300 according to the second embodiment supplies the room with outside air that has flown along the air-supply path indicated by the dotted line in Fig. 7 and passed through the heat exchangers 43, 43. At the same time, the heat exchanging ventilator 300 exhausts air inside the room outside that has flown along the air-exhaust path indicated by the continuous line in Fig. 7 and passed through the heat exchangers 43, 43. The heat exchanging ventilator 300 performs heat exchange ventilation by simultaneously supplying and exhausting the air while the heat exchangers 43, 43 are performing heat exchange.
When the bypass-air supplying path or the bypass air-exhaust path is opened, with the help of the damper, the air supplying fan 44 or the air exhausting fan 41 supplies inside the outside air or exhausts outside the air inside the room without passing through the heat exchangers 43, 43, thus supplying or exhausting air inside or outside as a normal ventilator without the heat exchange.
The heat exchanging ventilator 300 includes the temperature sensor 20c for sensing the temperature of the air blown into the room and the humidity sensor 20d for sensing the humidity of the air blown into
1713633-1 ]_8
inside-air outlet 37 (or the outside-temperature sensor 19c and the outside-humidity sensor 19d in the outside-air inlet 39), and the inside-temperature sensor 20a and the inside-humidity sensor 20b in the inside-air inlet 40.
These sensors detect temperatures and relative humidities of the air inside and outside the room. Based on results of the detection, absolute humidity of the air inside and outside the room is calculated from the saturated water vapor curve. Thus, the absolute humidity of the outside air and the absolute humidity of the inside air can be obtained. Therefore, for example, when the absolute humidity of the outside air is lower than the absolute humidity of the inside air, operation of the heat exchanging ventilator 300 can be controlled so as to increase the volume of ventilation air.
Explanation for a controlling device and a controlling method of the fan in the heat exchanging ventilator 300 of the second embodiment is same as those shown in Figs. 4 and 5. Therefore, explanation for the controlling device and the controlling method of the fan of the heat exchanging
