A front face plate and a sealing supporting plate are respectively provided with a vertical groove, and the vertical grooves clamp the front and the back flanges of an air heat exchanger; the sheet type air heat exchanger is a parallelopiped cylindrical body, and the heat exchange can be realized by the flow of the air in the reverse direction between adjacent layers; a ventilating blower and an exhaust blower are both arranged outside the room, and the air heat exchanger is arranged in the room. The material of the air heat exchanger adopts non-metal material which has the effects of silencing and sound isolation, and the noise in the room can be low.
Description
The utility model relates to a kind of outdoor two-way ventilation machine, and heat exchange is carried out in air intake and air draft in scavenging period, thereby room temperature is constant substantially before and after guaranteeing ventilation.Thereby it belongs to air conditioner ventilation and technical field of heat exchange.
People adopt the method for ventilation to discharge indoor foul atmosphere usually, suck outdoor fresh air, yet common ventilation fan is unidirectional ventilation, because very big hot and cold loss is brought in ventilation into, especially in air-conditioning, Heating Room, in the also easy inlet chamber of outdoor dust.
In patent application 93214293.1, the inventor has proposed a kind of indoor and outdoor two-way ventilation machine, because its special structure design, has realized that air-supply, air draft carry out simultaneously.When there is the temperature difference in indoor and outdoor, air-supply is carried out exchange heat with air draft in machine, effectively reclaim the air draft energy, heat exchanger effectiveness can reach 80%, thereby room temperature is remained unchanged substantially, greatly reduced because the energy charge that ventilation brings into for air-conditioning or heating installation is a kind of energy-conserving product that can effectively improve indoor environment.But because its pressure fan is in the indoor, room noise is bigger, and is to requiring the lower place of noise, just not too suitable as classroom, library, recording studio etc.
The purpose of this utility model provides a kind of indoor and outdoor two-way ventilation machine and (is called for short: ventilator), it send, exhaust blower is all in the outside, air heat exchanger is in the indoor, and owing to the noise reduction deadening of air heat exchanger makes its indoor side noise lower, complete machine structure is also more compact simultaneously.
The utility model has adopted reverse-flow air heat exchanger in design, the drawing and pulling type air cleaner, and the easy-opening front panel, silent ventilator etc., compact conformation, easy for installation, can directly install on the window or on the wall.The complete machine performance reaches higher level.Be widely used in the indoor and outdoor ventilation of room, office, public place, workshop, machine room, hospital etc., especially need place than low noise.Before and after ventilation, keep the room temperature substantially constant, and can stop in the outdoor dust inlet chamber isolating chamber external noise.
Technical solution of the present utility model is that ventilator is made up of casing, pressure fan, exhaust blower, air heat exchanger, powered air-purifying device, exhaust-air filter, front panel, sealing gripper shoe etc.Machine shape is a rectangle, can be installed on the window or in the wall hole.Pressure fan and exhaust blower all are positioned at casing by an outdoor side, about both or arranged side by side up and down.Air heat exchanger is positioned at casing by an indoor side.Front panel is pressed abd fixed on air heat exchanger in the machine.On the plate and on the sealing gripper shoe a vertical groove is arranged respectively in front, block the front and back flange of air heat exchanger, play fixing and sealing function.Between casing and the sealing gripper shoe is a vertical slit, and the powered air-purifying device is positioned at around here and can stitches extraction thus, has the air intake louver on the corresponding casing side.Front panel is an easy-opening, in order to changing powered air-purifying device and exhaust-air filter.The effect of sealing gripper shoe is to support blower fan, and seal isolation is sent, air draft side and pressure fan are imported and exported air-flow.
Air heat exchanger is the parallelepiped cylinder, by heat transfer plate and the stacked composing plate plate heat exchanger of space bar, its left and right sides face by casing is shut, and be parallel to the casing side, all outwards protrude the two sides of end, front and back, air-supply on one side, on one side air draft, the end, front and back is advanced accordingly, the air draft limit just in time is hexagonal relative edge.Demarcation strip is made concavo-convex corrugated, forms the parallel gas flow passage between ripple, and the air flue at middle part points to the indoor and outdoor direction, and both ends are folded to accordingly respectively, the air draft side.Stacked air heat exchanger one deck is the air-supply layer, and one deck is the air draft layer, and adjacent interlayer air reverse flow is also passed through the heat transfer plate heat exchange.Because the sealing function of ripple, adjacent interlayer air do not mix substantially mutually.The air-supply layer is parallel with the air flue of air draft layer at the middle part, reverse flow, and two ends intersect, because adverse current part area occupied is bigger, whole heat exchanger is countercurrent flow substantially, heat-transfer effect is good.
For reaching the purpose of sound insulation noise reduction, air heat exchanger material selection nonmetallic materials, heat transfer plate is preferably selected the material of heat and moisture transfer simultaneously for use, to reach the constant temperature and humidity ventilation.
The powered air-purifying device is board-like or folding leaf filter.Exhaust-air filter is board-like filter screen, is positioned at front panel.Give, exhaust-air filter all can be changed by the indoor.Open front panel with regard to replaceablely give, exhaust-air filter.The indoor is sent, is arranged mouth and all is positioned on the front panel.
