Abstract
The utility model relates to a scavenger fan with thermal energy recovery, which solves the problem that the heat energy loss when the heat exchanges. An inner core is fixed in the tabular shell. The inner core comprises a plurality of layers of gas inlet passages and gas outlet passages which are alternating stack up. The separation angle of the gas inlet passages and the gas outlet passages is 90 degree. Heat exchanging layers are between the gas inlet passage and the gas outlet passage. One end of the gas inlet passage is gas outlet opening of the gas inlet passage exposing to interior, and another end is gas inlet opening of the gas inlet passage exposing to outside. One end of the gas outlet passage is gas outlet opening of the gas outlet passage exposing to outside, and another end is gas inlet opening of the gas outlet passage exposing to interior. A gas inlet fun is arranged on the gas inlet passage, and a gas outlet fun is arranged on the gas outlet passage. The heat exchanging effect of the utility model is high, the cost is low, the installation is conveniently and the space of the room can't be occupied.
Description
(1) technical field under
The utility model relates to a kind of ventilation fan that is used for room ventilation, the particularly a kind of energy-conservation ventilation fan that can avoid that thermal energy loses in the room in, can carry out air exchange again.
(2) background technique
Along with the raising of people's living standard, use the family of air-conditioning more and more, but thing followed air-conditioning sickness is more and more.The major reason that air-conditioning sickness increases is exactly that indoor air is stale, bacterium is increased.But existing ventilation fan is also outdoor with indoor thermal energy discharge in ventilation, causes energy significant wastage.
(3) summary of the invention
The utility model provides a kind of energy-conservation ventilation fan of avoiding thermal energy loss in the room in order to overcome the deficiency of above technology.
The utility model is realized by following measure:
The utility model discloses a kind of energy recovery ventilation fan, at flat housing internal fixation one inner core is arranged, inner core is made up of several layers alternately laminated gas-entered passageway and exhaust passage, and the angle of gas-entered passageway and exhaust passage is 90 degree, is heat exchange layers between gas-entered passageway and the exhaust passage; Gas-entered passageway one end be towards indoor gas-entered passageway air outlet, the other end is for towards outdoor gas-entered passageway suction port; One end of exhaust passage be towards outdoor air outlet, exhaust passage, the other end is for towards indoor exhaust passage suction port; One supply fan is installed on the gas-entered passageway, ventilating fan is installed on the exhaust passage;
Energy recovery ventilation fan of the present utility model for filtered air, prevents that dust or foreign matter from entering ventilation fan, and described gas-entered passageway suction port is fixed with filter screen, and the exhaust passage suction port is fixed with filter screen.
Energy recovery ventilation fan of the present utility model in order to improve heat exchange efficiency, is fixed with corrugated barge board respectively in described gas-entered passageway and the exhaust passage.
Energy recovery ventilation fan of the present utility model is installed in indoorly for convenience, and described gas-entered passageway suction port is connected with the suction tude vertical with housing, and the air outlet, exhaust passage is connected with the vertical outlet pipe of housing.
Its heat exchange principle is, in summer, after room conditioning was opened, room temperature was lower than outdoor temperature, and indoor muddy cool air is discharged outdoor through the exhaust passage, and outdoor fresh hot air is in the gas-entered passageway inlet chamber.Because exhaust passage and gas-entered passageway are alternately laminated, are the heat exchange layers of good heat-transfer between exhaust passage and the gas-entered passageway, indoor cool air and outdoor hot air fully exchange, outdoor hot air turns cold, in winter, then outdoor cool air heating reaches the purpose of heat exchange.
The utility model has made full use of the advantage that the plate type heat exchanger volume is little, heat exchange efficiency is high, cost is low, the heat exchange when being applied to family's room ventilation.When carrying out the room ventilation, indoor air and outdoor air carry out sufficient heat exchange, the thermal energy loss when having avoided ventilation.
Because housing of the present utility model is planar, a kind of mounting type is, the utility model is installed in the window frame, installs very conveniently, do not take room space, do not influence the room layout.Another mounting type is, the utility model is fixed on the interior wall, makes a call to two through holes by special tool, respectively will suction tude and outlet pipe insert in the through hole and get final product.The utility model does not take room space, and is easy for installation, elegant in appearance.
The beneficial effects of the utility model are, have avoided the thermal energy loss during ventilation, the heat exchange efficiency height, and cost is low, and is easy for installation, do not take room space.

(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.
Embodiment 1
The concrete structure schematic representation of present embodiment as Figure 1-3.The profile of the ventilation fan of present embodiment is flat cuboid shell, and a flat little cuboid inner core is arranged in the shell of cuboid, and inner core is fixing in the enclosure.Inner core is made up of alternately laminated 20 layers of gas-entered passageway 4 and 20 layers of exhaust passage 5, and the angle of gas-entered passageway and exhaust passage is 90 degree, is a flat heat exchange layers 3 between gas-entered passageway 4 and the exhaust passage 5.Barge board and heat exchange layers 3 are to be made by the material of heat exchange conductive performance excellence.
Between four angles of housing and inner core, form four leg-of-mutton spaces, be respectively gas-entered passageway air outlet 7, air outlet, exhaust passage 8, gas-entered passageway suction port 9 and exhaust passage suction port 10.Gas-entered passageway suction port 9 is towards outdoor, and is fixed with a filter screen 6-1, is used to prevent that filter screen can freely take out in outdoor dust and the bacterium inlet chamber, is used for the cleaning of filter screen.Gas-entered passageway air outlet 7 is towards indoor, and fixes a supply fan 1, in outdoor air inspiration room.Air outlet, exhaust passage 8 is towards outdoor, and a ventilating fan 2 is installed, and indoor air can be discharged; Exhaust passage suction port 10 also is fixed with the filter screen 6-2 that can conveniently take out towards indoor.
Present embodiment is adapted to be mounted within the window frame in room, and after supply fan 1 and the ventilating fan 2 energising operations, air and the air in the exhaust passage in the gas-entered passageway fully carry out exchange heat by heat exchange layers 3, have avoided heat loss, have saved the energy.
The ventilation fan of present embodiment, its surface structure as shown in Figure 4, its internal structure is substantially the same manner as Example 1.Its difference is, is connected with one section suction tude vertical with housing 11 at gas-entered passageway suction port 9, and air outlet, exhaust passage 8 is connected with one section outlet pipe vertical with housing 12.
During installation, utilize special tool, make a call to two inlet hole and exhaust ports that are slightly larger than suction tude and outlet pipe on the wall, suction tude 11 and outlet pipe 12 are inserted inlet and outlet hole on the wall respectively, but can after fixing.
The ventilation fan of present embodiment can be installed on the indoor wall, and is easy for installation, do not take room space.
