A method for heat preservation of urea NaOH and Mg(OH)2 storage cabin, aiming at the ship equipped with SCR system, EGR system, iCER system and desulfurization system, and the ship needs to store urea, NaOH or Mg(OH)2. The condensate water of air conditioning unit is collected and introduced into the storage cabin by gravity, and the condensate water production and condensate water temperature of air conditioning unit are analyzed and calculated. Under the premise that the cabin capacity meets the conditions, the condensate water is used for cooling the urea cabin, and then discharged into the clean bilge water tank, which maximizes the cooling capacity of the condensate water. In winter or cold weather, when the air conditioning unit does not need to run, in order to avoid the temperature of the solution cabin being too low, the discharge water in the clean bilge water tank can be used to heat the storage cabin before discharging, which ensures that the storage temperature of urea, NaOH or Mg(OH)2 solution is 10~35℃.
