燃气锅炉与空气源热泵耦合运行策略OA

Combined with the outdoor temperature and time-of-use electricity price during the heating period in Beijing,the coupling operation strategy of gas-fired boiler and air-source heat pump was formulated to con-trol the start and stop of the two heating equipment at different times.Taking a typical day in severe cold pe-riod as an example,the costs of coupling operation and gas-fired boiler standalone operation are compared.Outdoor temperature and electricity price both have an impact on the coupling operation strategy.Compared with the operation of gas-fired boiler alone,the cost of coupling operation is decreased by 9.38％,and the cost of coupling operation is lower.
