Why doesn't the hotel air conditioner cool?

The reason may be: insufficient refrigerant. Usually, in order to save costs or neglect management, hotels do not replenish refrigerants in time, resulting in insufficient refrigerants. At this time, you can call the hotel front desk to solve it; The supply voltage is insufficient. However, this situation is relatively rare, and the voltage in general hotels is sufficient. In this case, you can only change rooms or hotels. The reason may also be that there are large heat sources indoors, such as heaters and computer mainframes. If there is a large heat source in the hotel room, it will also cause the body to feel not cool enough. At this time, just turn off the heat source or move it away. The reason may also be that the piping is too long. You can check whether the copper tube configuration is too long. If the piping is too long, it will slow down the heat transfer of central air conditioning and weaken the refrigeration effect. The reason may also be: aging equipment. Hotels generally have air conditioning. After the central air conditioner is installed and used for a period of time, it needs to be maintained, cleaned and maintained. If it is not maintained for a long time, it is easy to break down and shorten the service life of the central air conditioner. At this time, you can contact the hotel front desk to repair the air conditioner, or you can choose to change rooms. The reason may also be that the air conditioner itself is not powerful enough. At this time, you can only choose to change rooms.
