Description

Recuperation of heat air-treatment unit
Technical field
The utility model relates to the fresh air processor group of central air-conditioning.
Background technology
Recuperation of heat air-treatment unit belongs to the terminal new wind treatment facility of central air-conditioning; Major function is to make the dirty wind in outdoor new wind and the room before getting into the room, carry out heat exchange, by energy of exhaust air new wind is practiced thrift preliminary treatment, can make new wind obtain the cooling dehumidification in summer and handle; Can make new wind obtain to heat to add wet process in the winter time; Reclaiming thereby carry out energy, is a kind of health environment-friendly product, is widely used in air-conditioning places such as market, hotel, hospital, theater, office building.
Existing recuperation of heat air-treatment unit mainly is made up of pressure fan, exhaust blower, heat exchanger, filter and housing; Structurally have following problem: 1. heat exchanger is a horizontal heat exchanger, is installed between pressure fan and the exhaust blower, and not only device assembles is inconvenient; And take bigger space, unit inside; Make the unit overall volume bigger, material cost is higher, has increased investment of equipment; 2. perforate is as the passage of air-flow on the dividing plate, and structure is comparatively loaded down with trivial details, and the unit internal drag is bigger, and the causes motor input power is bigger, and the equipment running noises is bigger, has reduced the equipment heat exchange efficiency, has increased the noise pollution of equipment operating environment.
Summary of the invention
The utility model is to the deficiency of prior art, provides that a kind of equipment investment expense is low, heat exchange efficiency is high, the low recuperation of heat air-treatment unit of operation noise.
The utility model mainly is made up of pressure fan, exhaust blower, heat exchanger, filter and housing; Solving the technical scheme that its technical problem adopts is that vertical heat exchanger is installed in the housing; One side of heat exchanger is provided with pressure fan and exhaust blower respectively; The opposite side of heat exchanger is provided with dirty wind inlet plenum and new wind inlet plenum respectively; Enclosure interior is provided with dividing plate, and dividing plate links to each other with heat exchanger pressure fan, exhaust blower, dirty wind inlet plenum and new wind inlet plenum are separated, and pressure fan, exhaust blower, dirty wind inlet plenum and new wind inlet plenum and the corresponding side of heat exchanger are provided with ventilating opening respectively; The corresponding housing of dirty wind inlet plenum is provided with dirty wind inlet, on the new corresponding housing of wind inlet plenum fresh inlet is set, and new wind outlet is set on the corresponding housing of pressure fan, and dirty wind outlet is set on the corresponding housing of exhaust blower.
Above-mentioned dirty wind inlet plenum is provided with medium effeciency filter respectively with new wind inlet plenum.
The good effect of the utility model is:
Adopt vertical heat exchanger, pressure fan and exhaust blower are installed in the heat exchanger homonymy, unit appearance and size is reduced about 20%; The overall cost of unit is reduced significantly; Thereby greatly reduce the equipment investment expense, strengthened the market competitiveness, increased the unit inner space simultaneously; Thereby can design multistage filtering, improve air purification effect.
Need not perforate on dividing plate, simplified the internal partition structure, the use dividing plate will be blown, two strands of air-flows of air draft separate; Make the full and uniform heat exchange of new air draft air-flow, improved heat exchange efficiency, reduced internal drag; Reduce power input to machine, thereby reached energy-conservation purpose.
Low investment high benefit can reduce equipment investment and construction area, utilizes heat recovery technology energy-saving and cost-reducing, reduces equipment and systematic running cost significantly and uses.
Power of motor reduces, and equipment operation noise is lower, has reduced pollution from environmental noise.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein 1 pressure fan, 2 exhaust blowers, 3 heat exchangers, 4 dividing plates, 5 roughing efficiency air filters, 6 medium effeciency filters, 7 housings, 8 dirty wind inlet plenums, 9 new wind inlet plenums, 10 dirty wind inlets, 11 fresh inlets, 12 new wind export, 13 dirty wind export, 14 ventilating openings.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in the figure; Vertical heat exchanger 3 is installed in the housing 7; One side of heat exchanger 3 is provided with pressure fan 1 and exhaust blower 2 respectively, and the opposite side of heat exchanger 3 is provided with dirty wind inlet plenum 8 and new wind inlet plenum 9 respectively, and housing 7 set inside have dividing plate 4; Dividing plate 4 links to each other with heat exchanger 3 pressure fan 1, exhaust blower 2, dirty wind inlet plenum 8 and new wind inlet plenum 9 is separated; Pressure fan 1, exhaust blower 2, dirty wind inlet plenum 8 and new wind inlet plenum 9 are provided with ventilating opening 14 respectively with heat exchanger 3 corresponding sides, on the dirty wind inlet plenum 8 corresponding housings 7 dirty wind inlet 10 are set, and new wind inlet plenum 9 corresponding housings 7 are provided with fresh inlet 11; New wind outlet 12 is set on the pressure fan 1 corresponding housing 7, dirty wind outlet 10 is set on the exhaust blower 2 corresponding housings 7.
In above-mentioned dirty wind inlet 10 and the fresh inlet 11 roughing efficiency air filter 5 is set respectively.
Above-mentioned dirty wind inlet plenum 8 is provided with medium effeciency filter 6 respectively with new wind inlet plenum 9.
During work, dirty wind gets into dirty wind inlet plenum 8 from dirty wind inlet 10 through roughing efficiency air filter 5, handles through medium effeciency filter 6 again, gets into heat exchanger 3 by ventilating opening 14; New wind gets into new wind inlet plenum 9 from fresh inlet 11 through roughing efficiency air filter 5, handles through medium effeciency filter 6 again, gets into heat exchanger 3 by ventilating opening 14; In heat exchanger 3 with dirty wind heat exchange after; Deliver in the room by pressure fan 1, behind dirty wind and the new air heat-exchange, drain into outdoor by exhaust blower 2.
