DOI 10.3103/s0003701x13040038
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This study is a continuation of works [1–3]. The calculation results of daily variations in average hourly values of specific thermal yield and the efficiency of average-quality flat solar water-heating collectors (FSWHCs) in hot-water supply systems (HWSSs) are presented for typical days of the year; also, average monthly variations and annual values of these indexes for the considered collectors, which are based on the former calculations and depend on the temperature of the hot-water supplied to HWSS subscribers, are given.
