It is also possible to carry out the switching control automatically so that only one side of the floor air conditioner 3 and the fan coil unit 7 is operated.

  Next, the effect of Example 1 is demonstrated.

  In the air conditioning system of the first embodiment, the floor space 5 of the building 1 includes a living room 51 as a living room space, a hole 52 and a washroom 53 as a non-living room space, and a floor portion 1a as a floor of the living room 51. Is provided with a planar floor air conditioner 3, and a fan coil unit 7 as a blow-out type air conditioner is provided in the underfloor space 4 of the building 1.

Due to the residual heat, the hall 52 and the washroom 53 as a non-residential space can also be appropriately heated and cooled. When the temperature is extremely cold or extremely hot, hot water or cold water as a heat medium does not pass through the bypass pipe 15 from the surface of the heat pump 2. As a flow path that circulates separately between the floor air conditioner 3 and the fan coil unit 7, the direct supply of heat from the heat pump 2 sufficiently heats the hall 52 and the washroom 53 as a non-residential space. It can be carried out.

  An air conditioner 6 as an indoor air conditioner is provided in the living room 51, and the forward pipe 61 for the indoor air conditioner and the return pipe for the indoor air conditioner as a circulation pipe for circulating the heat pump 2 and the heat medium. 62 is connected.

  Next, Example 2 will be described.

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

  FIG. 4 shows a schematic configuration of a building 1A provided with the air conditioning system of the second embodiment.

  The air conditioning system of the building 1A of the second embodiment is mainly different from the first embodiment in that the bypass pipe 15 and the flow path switching valves 14A and 14B are not provided and are used only for heating, and therefore the drain 13 is not provided. .

  For this reason, it can implement with a simpler structure compared with Example 1. FIG.

  Moreover, since the planar floor air conditioner 3 performs only floor heating, it may be implemented without providing a heat insulating material in the lower part thereof.
