Abstract

In response to the problem of the lack of central heating in the winter and the high energy consumption for heating in the farmhouses in southern Xinjiang, an active-passive combined heating system of solar energy combined with biomass was proposed. In order to analyze the effects of passive renovation and combination of active and passive heating on the indoor thermal environment, a farmhouse in the southern Xinjiang area was selected for the study, and an experimental study was carried out after passive renovation and installation of active heating equipment. The results show that after the energy-saving renovation of the building envelope of the test house, the average indoor temperature increased by 11.77 °C compared to the normal farm house. Converting the south wall into heat-collecting storage wall on the basis of insulation and energy-saving renovation, which can increase the average indoor temperature by 2.84 ℃. The test house was heated by passive solar room heating combined with active equipment in the middle and at the end of the heating period. In the middle of the heating period, the active part provided 93% of the heat and the passive part provided only 7% of the heat. At the end of the heating period, the active part provided 80% of the heat and the passive part provided 20%. In addition, with the combination of active and passive heating, the test room temperature was above 18 ℃. This met the interior design temperature requirements for heating in cold regions in winter.
