Method for maintaining the temperature of an object, method for maintaining the temperature of an object in an engine room of a ship, and a ship

摘要

In order to suppress heat transfer from a first gaseous body (G1) around an object (20) to the object (20) and maintain the temperature (Tc) of the object (20) within a preset temperature range (Rt), a temperature maintenance gaseous body (G2) having a temperature (Tb) that is different from the temperature (Ta) of the first gaseous body (G1) and the temperature (Tb) within the temperature range (Rt) to be maintained by the object (20) is passed along the surface of the object (20) to cover the surface of the object (20) with the temperature maintenance gaseous body (G2) to thereby suppress heat transfer between the first gaseous body (G1) and the object (20) and maintain the temperature (Tb) of the object (20) within the temperature range (Rt) without especially providing a cooling device and the like.
