Abstract
A ventilation port is formed in a casing of an air conditioner for railway car use, and communicates with a passenger compartment to be air conditioned. An indoor heat exchanger housed in the casing performs heat exchange with air flowing in and out of the casing through the ventilation port. A return hole cover serving as a ventilation port cover has rigid portions that are rigid and bending portions that bend more easily than the rigid portions, and thus the return hole cover is transformable between a first form and a second form folded more compactly than the first form, the first form being a form in which the return hole cover is detachably fixed to the casing in a state in which the return hole cover covers the ventilation port from an interior of the casing.
Claims12
An air conditioner comprising:
- a casing in which is formed a ventilation port communicating with an air-conditioning target room to be air-conditioned;
- a heat exchanger housed within the casing, to perform heat exchange between the heat exchanger and air flowing into and out of the casing through the ventilation port;
- and
- a ventilation port cover comprising rigid portions that are rigid and bending portions that bend more easily than the rigid portions, enabling transformation between a first form and a second form in which the ventilation port cover is more compactly folded than when in the first form, the ventilation port cover in the first form being detachably fixed to the casing in a state that covers the ventilation port from an interior of the casing.
An air conditioner comprising:
- a casing in which is formed a ventilation port communicating with an air-conditioning target room to be air-conditioned;
- a heat exchanger housed within the casing, to perform heat exchange between the heat exchanger and air flowing into and out of the casing through the ventilation port;
- and
- a ventilation port cover having a stretching-contracting structure body freely stretching and contracting in an extension direction of the ventilation port, the ventilation port cover being mutually transformable between a first form and a second form more compactly contracted in the extension direction than the first form, the ventilation port cover in the first form covering the ventilation port from an interior of the casing.
A cleaning method comprising:
- cleaning a heat exchanger disposed within a casing in which is formed a ventilation port, the heat exchanger being for performing heat exchange between air flowing in and out of the casing through the ventilation port, the cleaning being performed in a state in which a compactable ventilation port cover covers the ventilation port;
- and
- compacting the ventilation port cover, and restarting the heat exchange between the heat exchanger and the air in a state in which the compacted ventilation port cover is disposed in a region other than between the ventilation port and the heat exchanger within the casing.
