The invention belongs to a composition member of a
solar light-heat central air-conditioning
system, which relates to the technical field of
solar electricity generation and heating. The device solves the problem that the use efficiency of the heat collecting
pipe and reflecting mirror combined type solar collecting device is low in spring and autumn. The composition member comprises a main framework, a heat collecting
pipe support frame, a heat collecting
pipe and a light reflecting and concentrating mechanism, wherein at least two
solar battery light reflecting and concentrating cover support devices form one group, at least two support shafts or shaft support structural bodies are arranged at each group, at least one
solar battery light reflecting and concentrating cover is movably fixed and connected on each support shaft or shaft support structural body, and the composition member is controlled and fixed in a certain state. The free selection and the proportion matching of the whole
system for obtaining heat and
electric power are realized. The composition member can obtain the
solar energy throughout the year according to requirements, can be used for heating and
air conditioning in winter and summer and can be used for
electricity generation in spring and autumn. Compared with the prior art, the composition member fully utilizes solar resources and photovoltaic and light-heat equipment and improves the performance
price ratio by one time.
