In air duct 7.Solar energy phase-change heat storage wall is at the same time to indoor heat release, heating indoor air.Therefore, room air forms heat
Circulate, effectively raise indoor thermal comfort.
As shown in Figure 4, the work at the night in winter of the ventilating system provided by the invention with solar energy phase-change heat storage wall
Pattern is：Close all ventilating openings, thermal-insulated blind 14 in rise, falls outer thermal-insulated blind 6.Hot-water heating system disables.Solar energy phase
The heat that each phase change layer of change heat accumulation wall stores daytime gradually discharges, and the air close to solar energy phase-change heat storage wall is heated,
Heated air-flow passes through to flowing to indoor heating with indoor air flow.Since phase-change material heat storage capacity is big, thermal inertia is strong, can
Heat for a long time at night.Meanwhile outer thermal-insulated blind 6 prevents the heat of solar energy phase-change heat storage wall from scattering and disappearing to outside.
As shown in Figure 5, the work of the summer day of the ventilating system provided by the invention with solar energy phase-change heat storage wall
Pattern is：Open outdoor air inlet 16, outdoor exhaust outlet 3 and lower ventilating opening 9, ventilating opening 2 in closings, the outer thermal-insulated blind 6 of rise,
Fall interior thermal-insulated blind 14, hot-water heating system normal use.Solar radiation is absorbed by solar energy phase-change heat storage wall, solar energy phase transition storage
Hot wall is heated, and the phase-change material in each phase change layer of solar energy phase-change heat storage wall reaches respective transformation temperature fusing and carries out phase transformation
Accumulation of heat.Bury the collection hot-water line 12 overlayed in solar energy phase-change heat storage wall and absorb heat generation hot water, reduce solar energy phase-change heat storage
The heat of wall.Air in air duct 7 is subject to solar radiation and solar energy phase-change heat storage wall to radiate and rise, and passes through outdoor row
Discharge in air port 3.Outdoor air is inhaled into interior by outdoor air inlet 16, is mixed with room air, then passes through lower 9 quilt of ventilating opening
In air suction channel 7.Therefore, it is indoor to form good gravity-flow ventilation, effectively reduce indoor temperature.
It will be appreciated from fig. 6 that the work at night summer of the ventilating system provided by the invention with solar energy phase-change heat storage wall
Pattern is：With the mode of operation of summer day, that is, outdoor air inlet 16, outdoor exhaust outlet 3 and lower ventilating opening 9 are opened, in closing
Ventilating opening 2, rises outer thermal-insulated blind 6, falls interior thermal-insulated blind 14, hot-water heating system normal use.Solar energy phase-change heat storage wall
The heat that each phase change layer stores daytime gradually discharges, the air in air duct 7 by solar energy phase-change heat storage wall radiate and on
Rise, discharged by outdoor exhaust outlet 3.Outdoor Cryogenic air is inhaled into interior by outdoor air inlet 16, is mixed with room air,
It is inhaled into again by lower ventilating opening 9 in air duct 7.Since the phase-change material heat storage capacity of solar energy phase-change heat storage within the walls is big,
Thermal inertia is strong, can radiate for a long time to air duct 7, and night can still strengthen indoor natural ventilating, and supplies life heat
Water.
The above-mentioned particular content that is described with reference to the drawings is simply schematical, not forms to the scope of the present invention
Limitation, the researcher of fields is in a kind of solar energy phase-change heat storage wall provided by the invention and with solar energy phase-change heat storage
The various modifications for being not required to make the creative labor and making on the basis of the ventilating system of wall or deformation are still in the protection of the present invention
In the range of.
