Description
Technical field
The present invention relates to a kind of electrical heat exchanger and utilize the air exchange system of electrical heat exchanger.
Background technology
Under the user in indoor activity such as breathes at state, airtight air in indoor will be As time goes on and gradually contaminated.Therefore, need at any time the air of indoor pollution is replaced with outdoor ozone, for this reason, generally use electrical heat exchanger and utilize the air exchange system of electrical heat exchanger.Wherein, above-mentioned electrical heat exchanger is a kind of under the state of the temperature that keeps room air, supplies with air outside and discharges the device of indoor air.
As shown in Figure 1, include in the existing electrical heat exchanger: heat exchange elements 5, it is installed on the air-breathing stream 10 that supplies to indoor passage as outdoor air, on the zone that intersects with the exhaust flow path 20 of the passage of discharging to the outside, and make above-mentioned outdoor air and room air carry out heat exchange as room air; Drawing fan 13, it is connected in above-mentioned air-breathing stream 10, sucks above-mentioned outdoor air, and it is discharged to indoor; Scavenger fan 23, it is connected in above-mentioned exhaust flow path 20, sucks above-mentioned room air, and it is discharged to outdoor.
Above-mentioned heat exchange elements 5 is installed on the zone that above-mentioned air-breathing stream 10 and exhaust flow path 20 intersect, and the inside of above-mentioned heat exchange elements 5 is formed with the stream (not shown) that stream (not shown) that room air passes through and outdoor air pass through.At this moment, electrical heat exchanger 1 utilizes temperature and psychrometric difference in the heat exchange membranes of the layer that constitutes different streams, make room air and outdoor air carry out heat exchange.
More detailed says, above-mentioned heat exchange elements 5 makes the stream of each air by having nothing in common with each other of occurrence temperature difference, under the effect of the high efficiency heat exchange membranes of the layer that constitutes above-mentioned different streams, carry out heat exchange by the moisture of exchange latent heat and the heat of exchange sensible heat.
In addition, general to constitute cross sections be dimetric quadrangular prism shape for above-mentioned heat exchange elements 5.
And a side of above-mentioned heat exchange elements 5 can be equipped with filter (not shown), and above-mentioned filter is used for the foreign substances that filtered air contains, and generally can combine with above-mentioned electrical heat exchanger dismounting.
Simultaneously, an end of above-mentioned air-breathing stream 10 is formed with and the outdoor air-breathing stream inflow entrance 11 that is communicated with, and its other end is formed with and the indoor air-breathing stream outlet 12 that is communicated with.And an end of above-mentioned exhaust flow path 20 is formed with and the indoor exhaust flow path inflow entrance 21 that is communicated with, and its other end is formed with and the outdoor exhaust flow path outlet 22 that is communicated with.
In addition, above-mentioned air-breathing stream 10 is provided with drawing fan 13, and above-mentioned drawing fan 13 is used for outdoor air is forced to suck, and it is supplied to indoor.Above-mentioned exhaust flow path 20 is provided with scavenger fan 23, and above-mentioned scavenger fan 23 is used for indoor contaminated air is forced to suck, and it is discharged to outdoor.Wherein, above-mentioned drawing fan 13 and above-mentioned scavenger fan 23 are arranged at the inside of suction/scavenger fan shell (housing) respectively.In addition, the front side of above-mentioned drawing fan shell and scavenger fan shell is equipped with the motor (not shown) that is used to drive said fans.
Below, the effect of the air exchange system of structure is as mentioned above described.
At first, when room air pollution under the situation to a certain degree, when supply and exhaust fan 23 is connected power supplys, room air will flow in the exhaust flow path 20 by exhaust flow path inflow entrance 21, room air through above-mentioned exhaust flow path 20 will cross heat exchange elements 5 with diagonal.Then, by the room air of above-mentioned heat exchange elements 5, after will flowing along above-mentioned exhaust flow path 20, by exhaust flow path outlet 22 to outdoor discharge.
Meanwhile, outdoor air flow in the air-breathing inflow 10 by air-breathing stream inflow entrance 11, and crosses the above-mentioned heat exchange elements 5 of perforation with diagonal.Then, by the outdoor air of above-mentioned heat exchange elements 5, after will flowing along above-mentioned air-breathing stream 10, supply to indoor by air-breathing stream outlet 12.
In said process, the room air and the outdoor air that connect above-mentioned heat exchange elements 5 will carry out heat exchange mutually, thereby will have the outdoor air of proper temperature to indoor discharge.
In addition, room air will be divided into both direction substantially and be discharged to the outside, at first, leaked-in air in the above-mentioned exhaust flow path inflow entrance 21, behind exhaust flow path the 1st ostium 24, to carry out heat exchange with the outdoor air that flows in the above-mentioned air-breathing stream inflow entrance 11, and discharge by above-mentioned heat exchange elements 5 to the outside; Perhaps, room air will be without above-mentioned heat exchange elements 5, but the pressure inhalation power by above-mentioned scavenger fan 23 directly is discharged to outdoor.
In the latter case, for room air directly is discharged to exhaust flow path outlet 22, and exhaust need be set with bypass flow path 26, by exhaust flow path inflow entrance 21 leaked-in airs, will use in the bypass flow path 26 in above-mentioned exhaust through exhaust flow path the 2nd ostium 25 and flow.And, flow to above-mentioned exhaust with in the bypass flow path 26 in order to make air, air damper (damper) can be set on the above-mentioned exhaust flow path inflow entrance 21.
According to aforesaid structure, under the less situation of temperature, the psychrometric difference of indoor and outdoors such as spring, autumn, room air is directly discharged without heat exchange elements 5, the pressure loss in the time of can preventing by above-mentioned heat exchange elements 5, reduce the load in the fan, and save the electric power that consumes.
But there is following several problem in above-mentioned electrical heat exchanger:
First, when carrying out architectural design, owing to be subjected to the restriction of ceiling height, the height of electrical heat exchanger will be restricted, and the height of heat exchange elements also will be restricted, consequently, the height-limited size of heat exchange area that will cause of heat exchange elements is restricted, thereby causes the electrothermal efficiency of electrical heat exchanger to reduce relatively.
The second, owing to the flow velocity of the air that passes through heat exchange elements is too high, can't effectively carry out heat exchange operation in the above-mentioned heat exchange elements, and make the efficient step-down of electrical heat exchanger.
The 3rd, because bending is bigger on the flow direction of air-breathing stream and exhaust flow path, thereby cause by the pressure loss of stream bigger.
