This paper presents a new rural energy usage mode based on biomass briquette boiler,which integrated cooking, water heating Kang, water heating bed, water heater into a system. The biomass briquette boiler produces hot water with high efficiency and low emission, the hot water can be sent directly into the heating system for room heating, sent into a special water heater for domestic hot water, and sent to water heating Kang or water heating bed for heating and ensure the comfortable of Kang's or bed's surface after reductions of temperature through mixing valve.METHODSIn order to verify the feasibility and the comfort of thisnewsystem, Airpark software was used to simulate these two living rooms based on the measured data. Simulated the indoor temperature of new heating system room and traditional heating room, analyzed PMV and PPD of these two living rooms, and quantify their thermal comfort.RESULTSSimulation results show that the average PMV of traditional heating room is around -1.19, while the average PMV of new heating model room is -0.10; and the average PPD of traditional heating room is 39.8%, while the average PPD of the new heating model room is 13.47%.CONCLUSIONSIt is obviously that the room with new heating system is more comfortable than the room with traditional heating system. In addition, comparing the economy analysis of these two heating systems, the new one has better economic performance through the life cycle. If this new system be widely used it will produce huge social and economic benefits
