  BACKGROUND ART Conventionally, an air conditioning system that can air-condition a floor space in a building with both a floor air conditioner that directly air-conditions the air and a floor air conditioner that indirectly air-conditions the floor space from the side of the floor through a floor is known. (See, for example, Patent Document 1).

JP 2007-78324 A

  However, in the conventional air-conditioning system such as the above-mentioned Patent Document 1, since the air-conditioning device for performing floor air-conditioning is provided in the space above the floor, the air-conditioning system occupies the space above the floor and air-conditioning for performing under-floor air-conditioning. Because the device is a blow-out type air conditioner, it underfloor air-conditions to the underside of the stairs and places that do not need to be underfloor air-conditioning, such as a storage unit, and uses waste heat energy. I could not say.

  Therefore, an object of the present invention is to provide an air-conditioning system with good energy efficiency without occupying a space above the floor with an air-conditioning device, and a building provided with the air-conditioning system.

The air conditioner is connected to the air outlet of the air outlet type air conditioner.

  Here, the floor space of the building is partitioned by a partition wall, and a living room space and a non-living room space are formed. An exhaust port for floor air conditioning is provided facing the non-living room space, The mouth may be connected to a suction part of the blow-out type air conditioner via a duct.

  Further, the radiation type air conditioner may be a heat radiation panel capable of radiating heat upward.

  Further, the blow-out type air conditioner and the radiation type air conditioner are of a heat pump type, and are preferably connected to a common heat pump device.

  Further, it is preferable that a heat insulating material is stuck on a peripheral surface of the foundation forming the underfloor space to form a heat insulating basic structure.

  Further, the blow-out type air conditioner may be installed below a place where it is not necessary to perform air conditioning under the floor.

  A building according to the present invention includes the above-described air conditioning system according to the present invention.

  Moreover, when the radiation type air conditioner is a heat radiation panel capable of radiating heat upward, it can be easily installed in a low underfloor space.

  Furthermore, the blow-out type air conditioner and the radiation type air conditioner are of a heat pump type, and when connected to a common heat pump device, a common heat pump device is used, so that the control structure can be simplified. it can.

  In addition, if a heat insulating material is attached to the peripheral surface of the foundation that forms the underfloor space to form a heat insulating foundation structure, the underfloor space is hardly affected by outdoor temperature, so underfloor air conditioning with less energy loss is required. It can be carried out.

  Furthermore, when the blow-out type air conditioner is installed under a place where it is not necessary to perform under-floor air conditioning, the blow-out type air conditioner can be easily installed so as not to disturb the under-floor air conditioning by the radiation type air conditioner. it can.
