Research on Energy Conservation and Carbon Reduction Technology of Ultra-low Energy Farmhouse in Sanjiangyuan Area
Taking an ultra-low energy demonstration farmhouse in Maduo County,Qinghai Province as example,TRNSYS software is used to simulate the envelope structure and energy use equipment system.The results show that the goal of ultra-low energy consumption can be achieved in the alpine cold areas by using the high-performance envelope structure in farmhouses.In terms of carbon reduction technical measures,solar photovoltaic heating and solar heat for domestic hot water have good carbon reduction effects,while air source heat pumps do not have obvious advantages in carbon reduction due to low efficiency caused by alpine cold climate.Among the three energy needs of heating,domestic hot water and lighting,the first two have great potential for carbon reduction transformation,especially making full use of solar energy for heating and domestic hot water.
