According to the Ninth Five Year Plan for the construction of central heating facilities in Beijing urban heating network and the development plan for 2010, 7 heat source plants, including the first and second heat sources, will be reconstructed and expanded, and the designed heating area will be increased by 5.92 million square meters. In addition, it is planned to build two new thermal power plants with an additional heating capacity of about 10 million square meters. In 2005, the heating area is expected to reach 83.59 million square meters, accounting for 31.13% of the city's building area [1]. And Beijing began to take environmental assessment as the central goal, focusing on the impact of various heating modes on environmental protection, and taking it as the benchmark and starting point for analysis and comparison, while taking into account the factors such as energy utilization efficiency, resource utilization, investment and economic benefits. Therefore, it is of great significance to carry out the research on the combined system of condensing boiler and heat pump in this area 。 In theory, when burning clean fuel natural gas, about 1.6kg of condensed water can be produced per standard cubic meter. For example, the fuel consumption of wns4.2-1.0/95/70-q hot water boiler is about 440nm3 / h. If 60% of the generated water vapor is cooled down, 440 × 1.6 × 0.6 = 422.4kg/h of water can be produced. It can be seen that the obtained water volume is considerable. If measures are taken to make use of this part of water, it will undoubtedly have a positive effect on some water shortage areas.
The combined system of condensing boiler and heat pump is an efficient energy-saving and environmental protection heat recovery system. In view of the current situation of heat supply in China: serious pollution, insufficient heat, urgent need to expand and build some new boiler rooms, lack of funds and other problems, adopting the combined system of condensing boiler and heat pump should be an energy-saving and environmental protection way worthy of discussion and application. The system can also produce considerable condensed water, which can be treated and used as industrial water and livestock water with low water quality requirements. And the heat pump part of the system can also provide cooling capacity for users in summer, which can be used as a small central air conditioning, with greater energy saving.
