Title:
COMBUSTION TYPE HEATER AND AIR-CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP2020106250
Kind Code:
A
Abstract:
To improve safety of a combustion type heater.SOLUTION: A combustion type heater 3 generates heat by flames. The combustion type heater 3 is disposed adjacent to a refrigerant circuit 20 filled with a combustible refrigerant. The combustion type heater 3 includes a combustion part 53 and a pore body 60. In the combustion part 53, flames are generated. The pore body 60 covers the combustion part 53 or the periphery of the combustion part 53. The pore body 60 at least partially covers a combustion space 54b to which the combustible refrigerant leaked from the refrigerant circuit 20 flows in and/or members (54a, 561, etc.) coming into contact with the combustible refrigerant leaked from the refrigerant circuit 20. A plurality of holes 65 are formed in the pore body 60. A diameter d1 of the hole 65 is equal to or smaller than a diameter d for extinguishing the flame of the combustible refrigerant.SELECTED DRAWING: Figure 9
