Typical problems of heat pump heating system in primary and secondary schools in northern China

 In recent years, a large number of heat pump heating systems have been applied to primary and secondary schools in northern China under the background of priority to basic education and great clean heating promotion. However, there are still many typical problems in the application of heat pump heating system to primary and secondary schools in northern China, resulting in failure to expected comfort and energy saving effect. Combined with the results of literature research and actual project testing, analyses the essential causes of typical problems, and puts forward the solutions, aiming to provide a reference for improving the heating comfort and system efficiency of primary and secondary schools in China.
