通过对影响水箱容积与集热面积合理配比取值若干问题的分析 ,提出了应根据设备投资、热水器服务地区的气象条件等因素 ,来考虑太阳能热水器水箱容积与集热面积合理配比取值的观点 ,给出了以最大收益为目标函数的计算公式 ,利用该公式可得到各种气象条件下的最优容积面积比参数 Based on the analysis of some problems that affect the reasonable ratio of water tank volume and collector area, the paper proposed that the reasonable ratio of water tank volume and collector area of ​​solar water heater should be considered according to the factors such as equipment investment and meteorological conditions of water heater service area , And gives the formula which takes the maximum return as the objective function. By using this formula, the optimal volume area ratio parameter under various meteorological conditions can be obtained
