possible heat load causes

Document Content and Description Below

1. List 5 possible heat load causes (and its standard quantities) from the hall when it is being used for a specific function, ie. exhibition, wedding, seminar etc. [CO1] Basically, there are many s ... ources of heat load that happen during the ceremony in hall the when it using. Large number of occupants, each of occupants will comes with their own gadget, lighting, and computers for PA system contributes to heat load causes which can make uncomfortable condition throughout the ceremony, especially for the important guests. Below is the description for each of the heat load causes from the hall when it is used for any ceremony during sunny day; a) Heat from human beings Occupants are major source of heat in building interiors. Considering that a human consumes hundreds of calories each day in the form of food, and part of this energy is released as heat during metabolic processes. The heat released by humans is even higher during intense physical activity, through perspiration. The heating effect of humans also increases depending on occupant density. As a result, the human contribution to the total heat load can be especially high in the hall. b) Heat from electrical and electronic appliances Indoor space in the hall are filled with electrical and electronic appliances such as lighting fixtures, smartphones for each occupants, laptop and LCD monitor. These appliances consume electricity and release some heat in air-conditioned spaces. c) Solar heat gain Three different ways in which heat from the sun can reach interior space of the hall which are conduction and convection. Conduction occurs across walls and roofs of the hall since they are exposed to a temperature difference between the hall interiors and the warmer outdoor environment. Convection refers to heat transfer from surfaces hot outdoor air or indoor air movement to surfaces at different temperatures. [Show More]
