The energy performance of PVAC in summer is better than that in winter due to the consistency between the photovoltaic production and building cooling load. The PVAC performance could be further improved by optimizing the system design and operation. In future applications, attention should be paid ...

近年来我国大力开发可再生能源,但是大规模的新能源远离负荷中心,难以就地消纳,成为制约能能源发展的一大瓶颈。如果我们把传统的冷热电三联供系统(Combined Cooling, Heating and Power,CCHP)和光伏发电系统以微网的形式结合起来,不仅使原来三联供系统更加清洁环保,也使光伏资源的利用率大大增加。CCHP 在 1990 年代以来发...
A modelling methodology is developed and used to investigate the technoeconomic performance of solar combined cooling, heating and power (S-CCHP) systems based on hybrid PVT collectors. The building energy demands are inputs to a transient system model, which couples PVT solar collectors via thermal...

Limit temperatures: +80 °C and -40 °C Holding time at limit temperature: 4 hours Heating and cooling-off time: 2 hours Relative humidity at 80 °C: 80% One test cycle takes one week to complete. Testing solution A modified testing solution is used for the salt spray test performed as...
An optimization coordination model for combined cooling,heating and electric power systems with complimentary generation of wind,photovoltaic cell(PV),gas and energy storage in different rate structures was presented. The model considers supplying of cooling,heating and power energy and power energy's ra...
On a 100 Watt PV panel, 10 W was lost from the panel heating up in the sun. After turning on the fans, the panel dropped over 10 °C in temperature, while regaining 5.5 W. Since the installed fans consumed about 3 W, this means that the fans cost no extra power but resulted in ...
A French-Lebanese research group has proposed a way to cool down PV modules by using air exhausted from heating, ventilation, and air conditioning (HVAC) systems. They showed that array performance improves when the cooling load rises.
