How to adjust the heat of hotel air conditioning

1. More advanced hotels generally adopt a four-tube internal system, allowing guests to switch between cooling and heating when staying on the operation panel.

2. If the air conditioner is not a four-tube, this air conditioner panel generally only has several functions, such as switching on and off, adjusting air volume and setting temperature. Residents of this air conditioning system can't cool and heat themselves.

3. At present, some hotels, such as Express Hotel, use multi-refrigerant system, that is, multi-online system. In this air conditioning system, tenants cannot adjust the cooling and heating by themselves.
