提出了用采暖系统作为太阳能集中热水供应系统的补充热源的设想,并利用费用年值法计算了这种系统在不同地区所需费用,以及在同一地区采用不同能源的热水供应系统所需费用,并将这些费用折算成系统每获得1GJ 热量所需费用进行比较。结果表明,利用采暖系统作为补充热源的太阳能集中热水供应系统的经济性较好。
The idea of using the heating system as a supplementary heat source for the solar hot water supply system was proposed and the annual cost method was used to calculate the cost of such a system in different regions and the hot water supply system that uses different energy sources in the same area Costs, and these costs are converted into the system for every 1GJ heat required for comparison. The results show that the use of heating system as a supplementary heat source of solar energy hot water supply system is better.
