Abstract: Air source heat pump integrated with hot water storage tank may enhance the efficiency of heating, and the volume of hot water storage tank is closely related to the thermal efficiency of the hot water system. Referring to the relevant formulas of building water supply and drainage design standards, this paper simulates the operation conditions of heat pump, and combined with the measured annual data of hot water using in a hospital, systematically discusses the adaptability of heat pump water production and seasonal hot water usage, as well as the actual regulating volume of hot water storage tank. Assumed the heat pump is altered by the working condition of the vernal equinox, the daily storage and discharge of the hot water tank can be accurately calculated, the hot water tank should charge 2.94 times of average hourly water yield of air pump during the peak water usage period. considering the safety and economy of the air source heat pump system, it is strongly recommended that the volume of hot water storage tank can be designed as the 5 ~ 6 times of hourly average water yield of air source heat pump, which can meet the usage of hot water for most of the time and it is inspected under various accidental conditions.

Abstract: Designing of a building is always for intended purposed, the housing of human beings should be specific to it task and should be enjoyed and provides needed comfort for the end user regardless of the surrounding circumstance. However environmental noise pollution is a problem affecting home users especially in developing country like Ghana. Ghanaians building industry is now in turned of foreign building design and it materials application without considering the socio culture implications. The traditional buildings in Ghana are basically one storey single family houses built with available local materials that is suitable for the clement and vernacular social cultural disciplines. Ghanaians general, built-up noise as a tool to exhibit powers unknown willing, these are observed on their daily social culture disciplines in worshiping, cooking, dancing, walking, talking and making fun. The new designs eventually put toll on the home users especially how to prepare fufu with traditional method wooden mortar, wooden pestle that lead contamination of fufu by mechanized method. The paper seek to concentrate on the courses of pounding fufu and it’s affiliated to activities in current modern buildings in Ghana. Special attention is paid on how traditional method could be used to prepare fufu in new buildings and it consequence to food contamination and the noise in the building.
