Environment Condition Contrast between Indoor and Outdoor of Photovoltaic Greenhouse

In order to test cooling effect in the actual production process and effects of photovoltaic panels layout on light，temperature，humidity and other data of photovoltaic greenhouse that has been built were tested.The experimental results showed that under the condition of damp curtain ventilator cooling system，compare to the outdoor environment conditions，temperature drop range was 0.5-7.8 ℃，Humidity difference range was 12.3-33%.In the case of photovoltaic panels layout using interval arrangement，scope of light transmittance was 32.64-80.96%，average transmittance was 66.27%.Thus，in the solar greenhouse damp curtain ventilator cooling system has good cooling effect，photovoltaic panels layout of light could meet demand of crop，and it is a practical technique with wide range of application prospect.
