Energy Saving Calculation Between Sliding Door and Revolving Door
Environmental Energy Consumption = Temperature difference ( T ) In/Out ×Air exchange amount ( M ) ×Air heat capacity ( C ) * . * Heat capacity is the measurable physical quantity that characterizes the amount of heat required to change a body's temperature by a given amount, the measurable physical quantity that characterizes the amount of heat required to change a body's temperature by a given amount. Here air capacity =1.2Kj/ m 3 . ▪ Take the city Hong Kong (China) as an example . Average temperature is about 27 ℃ . Inside temperature as human body comfortable level 20 ℃ . A common star hotel with 500 rooms, 60%-80% occupancy rate, with 1.5 person in every room, hosting 450-600 guests everyday, whose average daily entry and exit is 4-5 times each, coming with 1800-3000 times entry and exit totally. Considering other factors such as other visitors or food takeout etc., we choose a random value as 4320 . ▪ About the Doors * ...
