Because phase change heat storage material of the invention is pasty state or gel, the Volume Changes in phase transition process are small, Gu Qibao Leakage is difficult in aluminium box, using more safe and reliable.

In the present invention, the new Trombe wall of photovoltaic cell middle is as follows:

As shown in Fig. 2 in summer, the overhead gage 10 and indoor lower baffle plate 13 of interior of closing can so make on interior Air port 11 and indoor lower air port 12 are closed, while opening outdoor overhead gage 6 and outdoor lower baffle plate 8, can make outdoor Uptake 7 and outdoor lower air port 9 be in opening state.In summer day, the air heats of air flow channel 4 pass through siphon masterpiece Flowed from bottom to top with air is formed, the heat part that photovoltaic cell is produced is absorbed by PCM phase-changing heat accumulation plates, and a part can quilt The air of flowing takes away photovoltaic cell, and double action reduces the operating temperature of photovoltaic cell, it is ensured that photovoltaic cell is in high efficiency Working condition.Air flow channel 4 also acts as the effect that the heat for preventing photovoltaic cell from producing directly heats wall, compared to existing Trombe wall or photovoltaic Trombe wall, indoor heat load can be mitigated.

As shown in figure 3, in summer day, the overhead gage 10 and outdoor lower baffle plate 8 of interior of closing can so make indoor windward Mouth 11 and outdoor lower air port 9 are closed, while opening outdoor overhead gage 6 and indoor lower baffle plate 13, can make outdoor Uptake 7 and indoor lower air port 12 are in opening state.Air heats in air flow channel 4, by the effect of siphon power, can shape The air circulation approach of uptake 11 outside into the lower air port 12- air flow channel 4- rooms in room air-interior.One side air stream PCM The back side of phase-changing heat accumulation plate 3, can take away the backboard of photovoltaic battery panel 2 and be conducted through the heat for coming, and effectively reduce the temperature of photovoltaic cell Degree;On the other hand, room can in this way carry out gravity-flow ventilation.

As shown in figure 4, daytime in the winter time, the lower baffle plate 13 of indoor overhead gage 10 and interior is opened, can so make interior Uptake 11 and indoor lower air port 12 are in opening state, while close outdoor overhead gage 6 and outdoor lower baffle plate 8, can make room Outer uptake 7 and outdoor lower air port 9 is closed.In the winter time, the air heats of air flow channel 4, by siphon masterpiece With flowing that can from bottom to top.Room air by indoor lower air port 12, into PCM phase-changing heat accumulation plates 3 and wall insulating barrier 5 it Between air flow channel 4, heated air pass through indoor uptake 11 and flow into interior, can effectively lift indoor air temperature. Indoors while heating, the heat of air flow channel is also taken away, photovoltaic cell can so be cooled down, improve photovoltaic cell Operating efficiency.In the winter time at night, the release of phase-changing heat accumulation plate 3 latent heat, heats the air of air flow channel 4, can also improve night Indoor air temperature.

As shown in figure 5, night in the winter time, the overhead gage 10 of interior of closing and the lower baffle plate 13 of interior, indoor uptake 11 It is closed with air port under interior 12;Close outdoor overhead gage 6 and outdoor lower baffle plate 8, can make the He of uptake 7 of outdoor The lower air port 9 in outdoor is closed.All air ports are closed, prevents indoor heat from being outflowed by air port, maintain indoor temperature.

Above-described embodiment is not limited for the present invention preferably implementation method, but embodiments of the present invention by above-described embodiment System, it is other it is any without departing from Spirit Essence of the invention and the change, modification, replacement made under principle, combine, simplification, Equivalent substitute mode is should be, is included within protection scope of the present invention.
