WIPO Patent Application WO/2022/118754
Kind Code:
A1
Abstract:
Provided is an air-conditioning device which uses a combustible coolant, and for which sufficient safety is secured at a low cost. A first fan (31) produces air flow to an evaporator (24), which constitutes a heat exchanger. A furnace burner part (40), which constitutes a high heat part, heats air transmitted to an air-conditioned space. A casing (10) includes a second chamber (R2), a third chamber (R3), and a fourth chamber (R4) that constitute an arrangement space in which the evaporator (24), the first fan (31), and the furnace burner part (40) are arranged. An air-conditioning device (1) having an opening for communication between the outside and a first chamber (R1), the second chamber (R2), the third chamber (R3), and the fourth chamber (R4). An opening/closing part (60) opens/closes the opening. The opening/closing part (60) closes the opening during driving of the first fan (31), causing a state in which air cannot flow in/out between the outside and the arrangement space such as the second chamber (R2). The opening is opened when the first fan (31) is stopped, causing a state in which air can flow in/out between the outside and the arrangement space such as the second chamber (R2).
