Generally speaking, for smaller container houses, such as the common room of about 15 m², a 1 hp or 1.5 hp air conditioner should be sufficient. However, it should be noted that the insulation performance of a container room may be poorer than that of a common house, so it may be necessary to choose a slightly larger air-conditioner to ensure the cooling or heating effect.

When choosing an air-conditioner, apart from considering the size of the room, you also need to consider the specific structure of the container room, such as whether there are windows and skylights, and the sealing performance of the doors, which may affect the effectiveness of the air-conditioner.
