How to adjust the air conditioning and refrigeration in the hotel?

1, hotel central air conditioning generally has a panel control installed on the wall with buttons or touch screen control. First, turn on the light. 2. Adjust the mode to refrigeration or Snowflake logo mode for air conditioning and refrigeration. 3. Then adjust the air conditioning temperature and use the arrow keys to lower the temperature. 4. Use the "Wind" button to increase the wind power and cool down quickly. Finally, if there is a remote control, press the switch and start the air conditioner. As above, air conditioning and refrigeration will be started. Related knowledge science: 1, refrigeration process: when liquid freon enters the evaporator indoor unit through capillary, the space suddenly increases and the pressure drops, and the liquid freon will vaporize. Changing from liquid to gas is an endothermic process, and the evaporator will become cold after absorbing a lot of heat. After the fan of the indoor unit blows out indoor air from the evaporator, the indoor unit blows out cold air; Then the gaseous freon returns to the compressor to continue the compression cycle. 2. When using air conditioner, it is not advisable to adjust the temperature too low. It is suggested that the temperature of household air conditioner should be set at 26 to 27 degrees in summer. Every time the air conditioner is raised by 1 kwh, the electricity load will be reduced by 7%, reaching 10%. From a health point of view, the indoor and outdoor temperature difference in midsummer is about 4 to 5 degrees Celsius, which can prevent you from catching a cold and having a fever because of the excessive indoor and outdoor temperature difference, and you will be more likely to get "air conditioning disease".
