High Thermal Inertia

The modeling of the heating, ventilation, and air conditioning (HVAC) system is a prominent topic because of its relationship with energy savings and environmental, economical, and technological issues. The modeling of the HVAC system is concerned with the indoor thermal sensation, which is related to the modeling of building, air handling unit (AHU) equipments, and indoor thermal processes. Until now, many HVAC system modeling approaches are made available, and the techniques have become quite mature. But there are some shortcomings in application and integration methods for the different types of the HVAC model. The application and integration processes will act to accumulate the defective characteristics for both AHU equipments and building models such as nonlinear, pure lag time, high thermal inertia, uncertain disturbance factors, large-scale systems, and constraints. This paper shows types of the HVAC model and the advantages and disadvantages for each application of them, and it finds out that the gray-box type is the best one to represent the indoor thermal comfort. But its application fails at the integration method where its response deviated to unreal behavior.

Hvac System Modeling

The modeling of the heating, ventilation, and air conditioning (HVAC) system is a prominent topic because of its relationship with energy savings and environmental, economic, and technological issues. The modeling of the HVAC system is concerned with the indoor thermal sensation, which is related to the modeling of building, air handling unit (AHU) equipment’s, and indoor thermal processes.  This paper shows the HVAC model and the Winter Air Conditioning System, Summer Air Conditioning System. Until now, many HVAC system modeling approaches are made available, and the techniques have become quite mature.

The success or failure of science at sea depends on many factors, including the suitability of the vessel as a research platform and the support of the scientist's shipmates. This paper touches on a few of the classic examples of unsuitable ships provided for scientists and explorers, such as Wyville Thomson and Carpenter in the Lightning in 1868 and the relatively minor shortcomings of Scott's Discovery. But it concentrates on some of the personality clashes on research or exploration voyages ranging from Edmund Halley's experience of an insubordinate mate in the Paramore in 1698, to Nicolas Baudin's appalling relations with almost all of his companions in the Géographe and Naturaliste in 1800–1803. Since human nature does not change it is suggested that seagoing scientists should pay at least as much attention to the personalities of their prospective shipmates as to the characteristics of the ships in which they expect to sail.
