Study On The Application Of Radiant Cooling System In Marine Conference

In order to enhance the comfort of ships' working life and ensure the ship machinery and command instrument work in the appropriate temperature range, we must air conditioning the ship living accommodation, conference room, restaurant, engine room and other cabins. With the enhancement of people's needs, the existing conventional air conditioning systems cannot meet the comfort requirements, and a high proportion of energy consumption, be badly in need of replacement. Radiant cooling stand out in the air terminal devices as the high comfort,low power consumption, low noise and the other advantages. Radiant cooling has less application instances on ship, in order to improve the ship's comfort, this paper based on the ship conference room as the research object, established radiant cooling and fresh air system and used AIRPAK software simulation analysis. Specific work is as follows:First of all, numerical simulation of the radiant panel with replacement, circular plate,swirl diffuser and sides against wall air conditioning system, comparative analysis of four cases cabin thermal comfort?the effectiveness of supply air?Pollutant removal effectiveness indicators. The results show that collocation used radiant panel and replacement ventilation is the best effect.On this basis, analyzed the influence of radiation cooling with displacement ventilation on human thermal comfort factors, such as radiation plate temperature, supply air velocity, air temperature. Make advise of the parameter settings for radiant cooling.Finally, this paper compares and analyzes the comfort and air quality of the radiant cooling system and the whole air system. Radiant cooling air conditioning system can provided the cabins a better indoor thermal comfort; but in the same space, the air volume of the whole air conditioning system is large, and the airflow has a short residence time in the cabin, so it is more conducive to get a better air quality.
