Abstract
The heat loss coefifcient of large lfat plate collector can be obtained by theoretical calculation and experimental analysis. In this paper，ifrstly，the heat loss model of large lfat plate collector is established， and its theoretical heat loss coefifcient is obtained through theoretical calculation. Then，by measuring the inlet and outlet temperature of the large lfat plate collector，ambient temperature and lfow of heat collecting working medium，the actual heat loss coefifcient is obtained through experimental analysis. Finally，the theoretical heat loss coefifcient and the actual heat loss coefifcient of the large lfat plate collector are compared and analyzed to verify the feasibility of using the theoretical heat loss coefifcient to estimate the heat loss of the large lfat plate collector. The research results show that，on the premise of considering the engineering application conditions and allowable errors，using the theoretical calculation method to estimate the actual heat loss coefifcient of the large lfat plate collector can effectively improve the rationality of the large scale solar cross seasonal heat storage heating system design.关键词
