기상데이터 취득방법에 따른 건물의 냉난방부하 특성 연구

Abstract

As the buildings are consuming about 26 percent of the total national energy consumption amounts annually, the research on the energy saving technology for buildings will be very significant matter.

In this thesis, in order to apply the energy saving policy on the step of the onset of building construction, the characteristics of cooling and heating loads of building according to the acquisition methods of meteorological data are analysed by using the commercial simulation program of Esp-r.

For evaluating energy performance in the simulation program, the meteorological data is one of an important variables. As the current typical meteorological data in Korea does not consider the recent 5 year climate changes, it is necessary to compensate.

The purpose of this research is to compare the cooling and heating loads between the typical meteorological data and the actual measured one.

To get the actual meteorological data, the temperature, humidity, and amount of solar radiation for the five-storied building with 1,665m2 of building area was measured.

The actual measured meteorological data, the data of Korea Meteorological Administration, and the typical meteorological data were compared and the result showed that the Korea Meteorological Administration data was the same as the actual measured meteorological data.

The Korea Meteorological Administration data, therefore, could be used to evaluate the cooling and heating loads of all the buildings.

When the typical meteorological data is applied to the program that is obtained 30,369kWh as the cooling load and 86,049kWh as the heating load. Also 28,477kWh, 95,913kWh for the cooling and heating loads in 2006 and 24,121kWh, 74,677kWh for the cooling and heating loads in 2007 and 26,357kWh, 94,150kWh for the cooling and heating loads in 2008 and 20,026kWh, 89,199kWh for the cooling and heating loads in 2009 are obtained by the Korea Meteorological Administration data.

Consequently, by surveying the typical meteorological data and the Korea Meteorological Administration data from 2006 to 2009, the simulation program can be drew the cooling and heating loads.

Also, to assume a operating time of a building's air conditioning system in summer and winter season, it can be calculated to operate ratio of the system by using Maximum load calculation method.
