【摘要】：提出了一种太阳能热电新风机,为适应逐时变化的新风负荷需求,拟通过调节热电新风机的输入电压满足新风负荷要求.在此基础上分析了光伏组件、热电新风机、蓄电池三者之间的容量匹配关系,并建立了3个系统之间的容量匹配计算数学模型.以北京某新风量为90m3/h的办公室为例,模拟了7月21日至8月21日和1月1日至1月31日每天8:00至18:00热电新风机的使用工况.结果表明:所选光伏组件7月21日至8月21日发电量为94.24kW,热电新风机的总耗电量为64.35kW,连续阴雨天气时蓄电池的最大放电量为1.19kW,热电新风机的平均制冷系数达到2.50;光伏组件1月1日至1月31日发电量为50.29kW,热电新风机的总耗电量为40.54kW,连续阴雨天气时蓄电池的最大放电量为1.51kW,热电新风机的平均制热系数达到3.02.
[Abstract]:In this paper, a solar thermoelectric fresh air generator is proposed. In order to adapt to the demand of hourly change of fresh air load, it is proposed to meet the demand of fresh air load by adjusting the input voltage of the thermoelectric fresh air generator. On the basis of this, the photovoltaic module and thermoelectric fresh air machine are analyzed. The capacity matching relationship among the three storage batteries, and the mathematical model of capacity matching calculation between the three systems are established. Taking an office in Beijing with fresh air volume as 90m3/h, as an example, The operating conditions of the thermoelectric fresh air turbine from 8:00 to 18:00 from July 21 to August 21 and January 1 to January 31 are simulated. The results show that the selected photovoltaic module generates 94.24 kW of electricity from July 21 to August 21, and the total output of the thermoelectric fresh air generator is 94. 24 kW. The power consumption is 64.35 kW, the maximum discharge capacity of battery is 1.19 kW in continuous rainy weather, the average refrigeration coefficient of thermoelectric fresh air machine is 2.50, and the total power consumption of photovoltaic module is 50.29 kW from January 1 to January 31, and the total power consumption of thermoelectric fresh air turbine is 40.54 kW. The maximum discharge of battery is 1.51kW in rainy and overcast weather, and the average heating coefficient of thermoelectric fresh air machine is 3.02.
