Description
[technical field]
The invention relates to a kind of heat-exchange device, particularly about a kind of full-heat-exchange equipment that is used for the indoor air quality improvement and has full hot-swap feature.
[background technology]
In the daily life of reality, in order to guarantee indoor air quality, system often need install an air-conditioner, especially the personnel place of relatively concentrating, as assembly hall, large supermarket, office block etc., so that in time indoor pollutant and foul atmosphere are discharged outdoorly, and simultaneously will outdoor fresh air (wind newly) be supplemented to indoorly, reach the demand of human health standard.
Yet, the air of indoor and outdoor directly replaced will bring lot of energy loss, as being example with the summer, the energy loss that produces when replacing the indoor cold air of handling through air-conditioning with the very high new wind (hot blast) of outdoor temperature in large quantities is very big.
For solving above-mentioned room air pollution and energy savings problem simultaneously, full-heat-exchange equipment is applied to come into one's own day by day on the air-conditioning system, full-heat-exchange equipment is introduced outdoor fresh air with dilution chamber's internal contamination and get rid of the indoor foul atmosphere except that reaching, and between the convection current of above-mentioned two strands of air, carry out the full heat exchange of sensible heat (temperature) and latent heat (humidity) simultaneously, be indoor air quality, the good method that maintaining healthy is comfortable and energy-conservation effectively controlled in the air-conditioning system.
Full-heat-exchange equipment commonly used at present mainly contains rotary-type and two kinds of patterns of AC system, and wherein the full heat exchange filter core of AC system full-heat-exchange equipment is to be fixed in the casing, is fixing state, therefore is called the formula of leaving standstill or fixed full-heat-exchange equipment again.The operation principle that leaves standstill the formula full-heat-exchange equipment that is shown in Figure 1, its full heat exchange filter core 1 is with a saturating wet and airtight damp and hot exchange function paper wood, as fibrous paper base material etc. as dividing plate 2, waveform plate 4 with a plurality of air flow inlets 3 is set between the dividing plate 2 again, and be the cross arrangement of staggering at indoor I and these waveform plates 4 of outside II, thereby on full heat exchange filter core 1, form two strands of not connected indoor and outdoor gas channels, be indoor exhaust passage E-E and outdoor inlet channel F-F in the diagram, guarantee that two strands of air-flows can not mix.
When carrying out the indoor-outdoor air exchange by this full heat exchange filter core 1 respectively by blower fan directing exhaust gas and two strands of air-flows of air inlet, these two strands of air-flows since the existence of temperature difference and alternately by the time do the heat transmission, and simultaneously because 2 pairs of aqueous vapors of this dividing plate have permeability, therefore also can reach moisture matter and pass effect, thereby between exhaust and two strands of air-flows of air inlet, do the exchange of temperature and humidity, reach the effect that province can reach blowdown.Thisly can transmit energy, the heat exchanging process that can transmit humidity again then is full heat exchange.
Yet desire is brought into play the plurality of advantages of full heat exchange, in the design of full-heat-exchange equipment, still has following the have shortcoming to be overcome and the space of improvement:
(1) heat exchanger effectiveness has to be hoisted.Because it is to cross the passage that the multilayer that is separated to form by dividing plate is right-angled intersection by two bursts of air communication of air inlet and exhaust to finish that latent heat and sensible heat exchange, its exchange efficiency is determined by the function paper wood between channel partition fully, but the function paper wood is to be main demand with the strong characteristic of hydrophily, the lifting that passes for heat often can't take into account, the efficient of the sensible heat exchange space that still has greatly improved.
(2) it is inhomogeneous to enter the air flow rate of waveform plate air flow inlet.Because from wind direction that blower fan is blown into enter the wind direction of thin channel in the full heat exchange filter core often not on straight line, but at an angle, and entering the flow field end that is made of filter core and casing is a casing end plate over against primary air, be subjected to directly impacting the secondary gas flow of this end plate and primary air reciprocation and the steering effect that enters, make that flow field therebetween is very chaotic, the most of air flow rate that causes entering filter core only converges on the small part waveform air flow inlet, and uneven air quantity distribution is very unfavorable to the exchange efficiency of integral body between above-mentioned inlet.
[summary of the invention]
Technical problem to be solved by this invention is to overcome the deficiency of prior art, provides a kind of indoor air quality full-heat-exchange equipment that improves, so that its heat exchanger effectiveness is further promoted.
Another technical problem to be solved by this invention is to provide a kind of and improves the indoor air quality full-heat-exchange equipment, so that it is more even to enter the air quantity in each air channel of full heat exchange filter core.
For solving the problems of the technologies described above, full-heat-exchange equipment of the present invention comprises at least one blower fan, an one full heat exchange filter core and a heat pipe heat exchanger, this blower fan provides from indoor discharge foul atmosphere and from two strands of air-flows of outdoor introducing fresh air, corresponding above-mentioned two strands of air-flows are provided with that two staggered and not connected gas channel air feed circulations are out-of-date carries out full heat exchange on this full heat exchange filter core, this heat pipe heat exchanger comprises at least one heat pipe, this heat pipe comprises evaporator section and condensation segment and communicates with above-mentioned two gas channels respectively, described heat pipe is provided with most fins, described blower fan, heat pipe heat exchanger and full heat exchange filter core are arranged in the casing and are separated to form fan house and full heat-exchanging chamber, and wherein heat pipe heat exchanger and full heat exchange filter core are arranged in the full heat-exchanging chamber in the lump.
