Why doesn't the hotel turn on the air conditioner and it's not hot?

1. In the cold season, the hotel does not turn on the air conditioner, and the indoor temperature will still be in a more comfortable range.

2, reasonable design and maintenance, to ensure that the indoor temperature is appropriate. If thermal insulation materials and good ventilation system are used, the indoor temperature will be kept at a comfortable level, and it will not feel hot even if the air conditioner is not turned on.
