Abstract: For a polar transport ship, the design for cold environment is an important part of the design of the ship and its own system. In the respect of the air conditioning and ventilating design, the whole air intake system should be arranged with anti-freezing measures, such as installing anti-freezing shutters, at the intake according to the overall requirements and regional division, in order to ensure that the indoor temperature is above 0℃. According to the selection of different heating types and the calculation of heating power, the heating methods of the electrical heating, steam heating and glycol heating are applied in the accommodation, service and machinery spaces with consideration of the installation mode and space, in order to meet the temperature and humidity requirements of the air intake and thus to achieve the system anti-freezing. The ventilation system design of the “Xuelong 2” Ship in China has been summarized and studied for the design of the ventilation system for the polar transport ships in the future.
