  First, Example 1 will be described.

  FIG. 1 shows a schematic configuration of a building 1 provided with the ventilation air conditioning system of the first embodiment.

  First, such a building 1 includes a foundation bottom concrete 1b constructed as foundation insulation, a foundation side wall concrete 1c erected on the side edge, an outer wall portion 1d erected on the foundation side wall concrete 1c, and an outer wall thereof. It is mainly comprised from the ceiling part 1e which block | closes the upper end opening of the part 1d.

  In the space surrounded by the ceiling portion 1e and the outer wall portion 1d, an underfloor space 4 and an upper floor space 5 such as a living room are separated by a floor portion 1a as a floor. In consideration of underfloor heating from the underfloor space 4 side in particular, the floor portion 1a allows heat transfer between the underfloor space 4 and the abovefloor space 5, and has no heat insulating material attached thereto. Yes.

  Further, a foundation heat insulating material 10 such as glass wool is affixed to the underfloor space 4 side of the foundation side wall concrete 1c, so that the heat of the warm air in the underfloor space 4 is prevented from leaking as much as possible outdoors.

  Further, a humidity control material 17 is laid in the underfloor space 4.

  And the ventilation air conditioning system of Example 1 has the ventilation air conditioning apparatus 3 installed in the underfloor space 4 where this humidity control material 17 was laid.

  This ventilation air conditioner 3 can ventilate an indoor unit 3A of an air conditioner as an air conditioner having an air conditioning function and a dehumidifying function on the downstream side, and an air washer 3B as an air-liquid contact type air cleaner on the upstream side. It is the structure connected to.

  Here, the indoor unit 3A of the air conditioner as the air conditioner is of a heat pump type and is connected to the outdoor unit 2 installed outside the building 1.

  A heat medium circulation pipe 21 connected to the outdoor unit 2 is connected to the indoor unit 3A of the air conditioner.

  Further, the indoor unit 3A of the air conditioner is a unit having a dehumidifying function, and is provided with a drain 12 for drainage that penetrates from the underfloor space 4 to the outdoors.

  Further, the indoor unit 3A of the air conditioner has a floor blowing unit 32 and a floor blowing unit 33.

  Furthermore, the indoor unit 3A of the air conditioner has a built-in fan (not shown) capable of blowing air with various strengths from the floor blowing unit 32 and the floor blowing unit 33.

  Further, the on-floor blowing part 32 and the under-floor blowing part 33 are provided with on-off valves 32a and 33a made of an electric damper or the like, respectively.

  Here, the air washer 3B as a gas-liquid contact type air purifier has an outside air suction portion 31A and an inside air suction portion 31B.

  The floor 1a is provided with an exhaust port 6 with a grill and two types of air supply ports 7 and 9.

  Here, the air supply port 9 communicates directly with the underfloor space 4 without passing through the duct, and the other air supply port 7 is connected to the outlet 32 for the floor of the indoor unit 3A of the air conditioner by the duct 82. Has been.

  The outside air suction part 31A of the air washer 3B is connected to the outside air inlet 11 provided in the foundation side wall concrete 1c by a duct 81.

  Here, a suction fan 16 is provided in the duct 81.

  Furthermore, the inside air suction portion 31 </ b> B of the air washer 3 </ b> B is connected to the exhaust port 6 by a duct 83.

  The duct 83 is connected to the inside air discharge port 14 provided in the foundation side wall concrete 1c by the duct 84.

  Here, a discharge fan 15 is provided in the duct 84.

  In order to make the air quantity for ventilation smaller than the air quantity for air conditioning, ducts 81 and 84 having an inner diameter smaller than the ducts 82 and 83 are used.

  The floor space 5 is provided with a controller 13 for setting a desired operation pattern.

  Next, the operation pattern of the ventilation air conditioning system of Example 1 will be described.

  First, the pattern at the time of heating operation is demonstrated.

  When it is desired to warm the floor space 5 only by heating having immediate effect, the on-off valve 32a of the on-floor outlet 32 of the ventilation air conditioner 3 is opened, and the on-off valve 33a of the below-floor outlet 33 is closed. .

  Then, when the ventilation air conditioner 3 is operated, as shown in FIG. 2, warm air convects only in the floor space 5 and the floor space 5 is immediately warmed.

  When the floor space 5 is desired to be heated only by underfloor heating, the on-off valve 32a of the on-floor blowing part 32 of the ventilation air conditioner 3 is closed and the on-off valve 33a of the below-floor blowing part 33 is opened.

  When the ventilation air conditioner 3 is operated, the underfloor space 4 is immediately warmed as shown in FIG. 3, and the heat is transmitted to the overfloor space 5 mainly via the floor portion 1 a. Warm up evenly.

  When it is desired to warm the floor space 5 with both immediate heating and underfloor heating in the severe cold season of winter, the on-off valve 32a of the floor blowing section 32 of the ventilation air conditioner 3 is opened and the floor blowing is performed. The on-off valve 33a of the part 33 is also opened.

  When the ventilation air conditioner 3 is operated, as shown in FIG. 4, the warm air convection only in the floor space 5 is transmitted to the floor space 5 mainly through the floor portion 1a, and the floor space 5 is made uniform. With the heat that warms up evenly, the space 5 on the floor immediately and uniformly warms up evenly.

  In any heating operation, the air in the floor space 5 is humidified because the air passes through the air washer 3B.

  Further, during the heating operation for performing underfloor heating shown in FIGS. 3 and 4, the warm air blown from the underfloor blowing portion 33 is adjusted to an appropriate humidity by contacting the humidity control material 17. .

  Here, the humidity-controlling material 17 with moisture is naturally dried by dry air in winter when the ventilation air conditioner 3 is stopped.

  Next, the pattern during the cooling operation will be described.

  When it is desired to cool the floor space 5 by cooling, the on-off valve 32a of the on-floor blowing section 32 of the ventilation air conditioner 3 is opened, and the on-off valve 33a of the below-floor blowing section 33 is closed.

  Then, when the ventilation air conditioner 3 is operated, as shown in FIG. 2, cold air is convected only in the floor space 5, and the floor space 5 is immediately cooled.

  In this cooling operation, since air passes through the air washer 3B, the air is dehumidified by the dehumidifying function of the indoor unit 3A of the air conditioner.

  Next, a pattern during the air cleaning operation will be described.

  When it is desired to immediately clean the air above the floor space 5, the on-off valve 32a of the on-floor outlet 32 of the ventilation air conditioner 3 is opened, and the on-off valve 33a of the under-floor outlet 33 is closed.

  When the ventilation air conditioner 3 is operated, as shown in FIG. 2, air is convected only in the floor space 5, and the air in the floor space 5 is immediately cleaned.

  In the air purifying operation having this immediate effect, since air passes through the air washer 3B, it is dehumidified by the dehumidifying function of the indoor unit 3A of the air conditioner in summertime when the humidity is high. In winter, when humidity is low, the dehumidification function may be stopped and humidified.

  When it is desired to clean the air above the floor space 5 without relying on the air conditioner 3A as much as possible, the on-off valve 32a of the on-floor blowing section 32 of the ventilation air-conditioning apparatus 3 is closed and the on-off valve 33a of the below-floor blowing section 33 is opened. And

  Then, when the ventilation air conditioner 3 is operated, as shown in FIG. 5, first, air passes through the underfloor space 4 where the humidity control material 17 is laid, and then air convects in the overfloor space 5. Air is cleaned.

  In the air cleaning operation that does not rely on the air conditioner 3A as much as possible, the air passes through the air washer 3B. When the operation of the ventilation air conditioner 3 is stopped, such as at midnight when the air is cooled, the humidity control material 17 with moisture is dehumidified by the dehumidifying function of the indoor unit 3A of the air conditioner using relatively inexpensive midnight power. However, it may be in a dry state. Moreover, in the winter where humidity is low, the dehumidifying function of the indoor unit 3A of the air conditioner may be stopped and humidified.

Here, in any operation, the amount of air sucked from the outside air inlet 11 by turning the suction fan 16 is set to about 150 m ³ / h, and the discharge fan 15 is turned to discharge from the inside air outlet 14. The amount of air used was approximately the same, approximately 150 m ³ / h.

The amount of air circulating through the floor space 5, that is, the amount of air sucked from the exhaust port 6 was about 650 m ³ / h.

  In short, heat loss was reduced by making the amount of air for ventilation smaller than the amount of air for air conditioning.

  However, these numerical values are appropriately changed in accordance with the relationship such as the size of the space 5 on the floor.

  Next, the effect of Example 1 is demonstrated.

  In the ventilating air-conditioning system according to the first embodiment, the ventilating air-conditioning apparatus 3 is installed in the underfloor space 4 of the building 1, and the ventilating air-conditioning apparatus 3 is an air conditioner as an air-conditioning apparatus having a downstream air-conditioning function and a dehumidifying function. The indoor unit 3A of the conditioner and an air washer 3B as a gas-liquid contact type air purifier on the upstream side are connected so as to allow ventilation.

  The ventilation air conditioner 3 is provided on the air washer 3B side with an outside air suction portion 31A communicating with the outside air inlet 11 provided in the foundation side wall concrete 1c of the building 1 via the duct 81, and the air conditioner An underfloor blowing section 33 is provided on the indoor unit 3 </ b> A side, an air supply port 9 is provided in the floor 1 a of the building 1 for communicating the above-floor space 5 and the underfloor space 4. The humidity conditioning material 17 is laid.

  With such a configuration, ventilation such as air purification and air conditioning such as air conditioning and humidity control can be managed and controlled simultaneously.

  Moreover, since the humidity control material 17 is provided in the underfloor space 4, it is possible to adjust the humidity of the high-humidity air that has passed through the air washer 3B without depending much on the dehumidifying function of the indoor unit 3A of the air conditioner. .

  In addition, the air washer 3B as a gas-liquid contact type air purifier is used as a filter, and since it is not necessary to replace the filter, it is substantially maintenance-free.

  Here, an exhaust port 6 is provided in the floor portion 1 a, and an inside air suction portion 31 B communicating with the exhaust port 6 via a duct 83 is provided on the air washer 3 B side of the ventilation air conditioner 3. 6, the air in the floor space 5 can be sucked, and the inside air discharge port 14 provided in the foundation side wall concrete 1 c of the building 1 communicates with the duct 83 through the duct 84. Through this, a part of the air in the floor space 5 can be discharged to the outside of the building.

  For this reason, since the ventilation route and the air conditioning route become clear, ventilation such as air purification and air conditioning such as air conditioning and humidity control can be efficiently managed and controlled simultaneously.

  In addition, the amount of air sucked from the outside air inlet 11 and the amount of air in the floor space 5 discharged from the inside air outlet 14 are substantially the same, and the amount of air for ventilation passes through the floor space 5. It is made smaller than the amount of air for circulating air conditioning.

  For this reason, since heat loss due to ventilation is small, ventilation such as air purification and air conditioning such as air conditioning and humidity control can be managed and controlled more efficiently at the same time.

  Further, on the indoor unit 3A side of the air conditioner of the ventilation air conditioner 3, a floor outlet 32 communicating with the air supply port 7 different from the air supply port 9 provided in the floor 1a and the duct 82 is provided. Is provided.

  For this reason, warm air or cold air blown out from the blow-out unit 32 on the floor blows out from the other air supply port 7 to the above-floor space 5 and immediately warms or cools the above-floor space 5. Air conditioning such as humidity and ventilation such as air purification can also be performed.

  On-floor outlet 32 and on-floor outlet 33 on the indoor unit 3A side of the air conditioner of ventilation air conditioner 3 are provided with on-off valves 32a and 33a, respectively. The air-conditioned air blowing and the air-conditioned air blowing from the underfloor blowing section 33 can be controlled independently of each other.

  For this reason, by opening and closing the on-off valves 32a and 33a, air-conditioning and air purification having immediate effect from the on-floor blowing part 32, and under-floor heating from the under-floor blowing part 33 and the dehumidifying function of the indoor unit 3A of the air conditioner It is possible to easily perform switching control between air purification and as little as possible.

  Furthermore, the indoor unit 3A of the air conditioner of the ventilation air conditioner 3 is a heat pump type, and is connected to the outdoor unit 2 installed outdoors.

  For this reason, since a heat pump is used, it can be excellent in energy saving performance.

  The underfloor space 4 is surrounded by a floor portion 1a as a floor of the building 1, a foundation bottom concrete 1b, and a foundation side wall concrete 1c, and a foundation heat insulating material 10 is attached to the foundation side wall concrete 1c.

  For this reason, underfloor space 4 is made into a heat insulation structure, and underfloor heating with high energy efficiency can be performed without leaking the heat of warm air in underfloor space 4 to the outdoors as much as possible.

  Since the building 1 according to the first embodiment is configured to include the ventilation / air conditioning system according to the first embodiment, it can be a building having the above-described effects.

  In addition, since the ventilation air conditioner 3 and the like are installed in the underfloor space 4, the above-floor space 5 is not occupied and can be used effectively, and the design appearance is good.

  Next, Example 2 will be described.

  In addition, the description which attaches | subjects the same code | symbol about the description of the part same or equivalent to the content demonstrated in Example 1, and demonstrates.

The main difference from the building 1 of the first embodiment is that the duct 82 and the on-off valve 33a of the underfloor outlet 33 are not provided.

  For this reason, it is suitable when the floor space 5 does not require air-conditioning and air-conditioning having immediate effects, and the structure of the ventilation air-conditioning apparatus 30 can be simplified.

  Moreover, since it is not necessary to provide another air supply port 7, the design appearance of the floor space 5 can be improved.

  Other configurations and functions and effects are substantially the same as those in the first embodiment, and thus description thereof is omitted.

  As mentioned above, although the form for implementing this invention was explained in full detail based on Example 1, 2 with reference to drawings, specific structure is not restricted to these Examples 1 and 2, but this invention.
