A Study on Operational Pattern and Heat-storage Capacity of Micro Co-generation System for House Use Based on Minute-order Hot Water Load

Abstract

In recent years, introduction of micro co-generation system (μCGS) is expected to be a promising measure for improving energy efficiency in house. This paper discusses an operation pattern and heat-storage capacity of μCGS introduced in house use by using hot water load pattern expressed in minute. The simulation results reveal that (i)the introduction of μCGS drastically contributes to energy saving, (ii)the required heat-storage capacity turned out to be in feasible volume range, (iii)the calculation based on hourly averaged hot water load patterns underestimates the heat-storage capacity, (iv) when reverse power flow is No.accepted, value of μCGS as a hot water supply is diminished because operation of μCGS is considerably restricted and μCGS canNo. supply sufficient hot water.
