Preliminary Results for the First Year of Operation of a Seasonal Storage Solar Combisystem for a Single Detached House

摘要

This work describes the operation of a solar combisystem equipped with a buried water tank for seasonal storage.The combisystem supplies space heating and domestic hot water to a single-detached house in a cold climate. Thesystem was operated over the summer of 2017 through spring of 2018, and achieved solar fractions of 66% and 60%for space heating and domestic hot water, respectively. However, a number of issues prevented consistent operationand/or monitoring of the system, and the solar thermal array was found to underperform significantly. Thus, theresults of this cycle should not be taken as the definitive performance of such a system. The data collected from thesystem’s first year of operation will be used to develop and validate models of the seasonal storage tank and othersystem components.
