Air conditioning systems and houses

Abstract

To provide an underfloor air conditioning system which is ductless, requires no duct piping, and sufficiently performs a cooling / heating function.SOLUTION: An air conditioning system takes in conditioned air of an air conditioner 15 into an underfloor space 8 to condition the air in above-floor spaces 2, 3. The air conditioner 15 is provided with an air suction part 15a and an air blow-out part 15b. During heating operation, warm air is blown out; during cooling operation, cool air is blown out. The underfloor space 8 is in a form of a highly airtight and highly heat insulating chamber shielded from outside and is provided with a suction port 20 opening to the air blow-out part 15b of the air conditioner 15 and an air supply port 21 opening to floor surfaces 6a, 7a in the above-floor spaces 2, 3. The air supply port 21 is provided with an air supply device 16 which blows out and supplies the conditioned air in the underfloor space 8 to the above-floor space 2, 3. Thus, when the conditioned air blown out by the air conditioner 15 is blown out and supplied for the above-floor spaces 2, 3 by air supply devices 16,16, . . . via the underfloor space 8 during the heating / cooling operation.SELECTED DRAWING: Figure 1
