Heating

The process in which the ambient temperature is raised by adding heat to the air, to reach higher air temperature. Shipboard heating is carried out by different means: reheaters are used in a central-station of air-conditioning system with the cooling function turned off; reheaters and preheaters are used in supply ventilation systems; and convection or radiant heating is used in spaces not equipped with either an airconditioning or supply air ventilation system.
