[Abstract]:The hybrid gas-fired heat pump system (HPGHP) combines the hybrid power technology with the gas-fired heat pump (GHP). It is a new type of air conditioning equipment which can provide cooling, heat and domestic water for buildings. In this paper, the economic analysis and life cycle carbon emission evaluation of hybrid gas-fired heat pump system are carried out. The main contents are as follows: (1) the HPGHP system is divided into three subsystems: driving system, heat pump system and waste heat recovery system. The thermodynamic and dynamic matching relations among the three subsystems are analyzed. The simulation platform of hybrid gas-fired heat pump system is established based on Simulink, and the operating characteristics of the heat pump system are analyzed. The simulation data such as gas consumption and driving torque are compared with experimental data to verify the effectiveness of the simulation platform. The fuel consumption, fuel consumption and fuel conversion rate of hybrid gas-fired heat pump system are taken as the economic research index. The economy of hybrid gas heat pump and ordinary gas heat pump is compared and analyzed. (2) A typical office building load model is established by using DEST software, and the distribution of cooling and heat load and the running time of air conditioning system are analyzed. Based on the HPGHP simulation platform, the energy consumption in Beijing, Nanjing and Xi'an is analyzed by using the primary energy utilization ratio (PERC) in the refrigeration season and the primary energy utilization ratio (PERh) in the heating season as the evaluation index, and the general gas heat pump (GHP) and the electric driven heat pump (EHP) are analyzed in Beijing, Nanjing and Xi'an. According to the current electricity and natural gas prices in the three cities, the annual operating costs of the three schemes are calculated. On the basis of the current energy price, the hybrid gas heat pump (HGHP) has obvious economy. The model of carbon emission calculation in the life cycle of HEHP system is established by using the electric driven heat pump with the highest operating cost of cold and heat source. The equivalent CO2 emissions are calculated at the transportation stage and the operation stage, and compared with the GHP- EHP, and the advantages in carbon reduction are analyzed. Based on the life cycle evaluation software, ECO-Indicator 99 is used to evaluate the environmental impact in the life cycle of HPGHP system. All kinds of environmental impacts are classified into three kinds: human health, ecological quality and resource consumption. The main source of environmental impact assessment index 5678.231Ptin the whole life cycle of hybrid gas-fired heat pump is the stage of production installation and operation. The environmental impact caused by natural gas use accounts for 92.9% of the total environmental impact of the system.
