Description

Total-heat exchanger
Technical field
The present invention relates to total-heat exchanger, relate in particular to a kind of logic control method of total-heat exchanger.
Background technology
Usually since in the interior space RB of live body, for example the air in the interior space is little by little contaminated at confined space as time goes by.Therefore, be necessary to use fresh outdoor air to replace contaminated air in the interior space continually.For this reason, use the ventilating system of utilizing total-heat exchanger usually.
Figure 1 shows that the structural representation of the total-heat exchanger of prior art.As shown in Figure 1, total-heat exchanger comprises: steam line 10 is used to guide outdoor air to arrive the interior space; Discharge duct 20, it is outdoor to be used to guide room air to arrive; And heat exchange elements 50a, be used to make room air and outdoor air to carry out heat exchange.This total-heat exchanger can also comprise: air supply fan 13 is used for the suction chamber outer air and institute's inhaled air is offered the interior space; And exhaust fan 23, be used to suck room air, and be discharged to the room air that is sucked outdoor.Heat exchange elements 50a is arranged on the zone that outdoor airflow that is guided by steam line 10 and the indoor air flow that is guided by discharge duct 20 intersect each other.Heat exchange elements 50a makes room air and outdoor air carry out heat exchange, comprises utilizing the sensible heat exchange that temperature difference is carried out between room air and the outdoor air and utilizing the latent heat exchange that psychrometric difference carries out between room air and the outdoor air,
At length, in heat exchange elements 50a, form the first hot switching path (not shown) and the second hot switching path (not shown) that room air and outdoor air pass through respectively.The heat exchange membrane (not shown) that this first hot switching path and second hot switching path are had outstanding thermal characteristics defines.Therefore, when the room air with temperature difference and psychrometric difference and outdoor air during respectively by the associated hot interchange channel, room air carries out heat exchange through heat exchange membranes and outdoor air.The filter (not shown) can be arranged on the side of heat exchange elements 50a.This filter is used for filtered air to remove the impurity that comprises at air, and wherein this filter is detachably connected to heat exchange elements 50a.
Steam line inlet 11 is arranged on an end of steam line 10.This steam line inlet 11 is communicated with outdoor.Steam line outlet 12 is arranged on the other end of steam line 10.This steam line outlet 12 is communicated with the interior space.Similarly, discharge duct inlet 21 is arranged on an end of discharge duct 20.This discharge duct inlet 21 is communicated with the interior space.Discharge duct outlet 22 is arranged on the other end of discharge duct 20.This discharge duct outlet 22 is communicated with outdoor.Air supply fan 13 is arranged in the steam line 10, to offer the interior space from outdoor pressure suction chamber outer air and with institute's inhaled air.Exhaust fan 23 is arranged in the discharge duct 20, to force the air of suck pollution and to be discharged to institute's inhaled air outdoor from the interior space.The two is installed in air supply fan 13 and exhaust fan 23 respectively in air supply fan housing and the exhaust fan housing.The motor (not shown) is separately positioned on the front side of air supply fan housing and exhaust fan housing.
Described total-heat exchanger mainly is discharged to room air outdoor by two streams.Promptly, about first stream, the air that is incorporated into discharge duct 20 by discharge duct inlet 21 carries out heat exchange by behind the downtake pipe road bullport 24 with 11 outdoor airs that are incorporated into steam line 20 that enter the mouth by steam line, be discharged to outdoorly then, this kind pattern is referred to as the all-pass pattern.On the other hand, about second stream, the suction that is deflated fan 23 by discharge duct inlet 21 air that are incorporated into discharge duct 20 directly is discharged to outdoor, and by heat exchange elements 50a.About latter event, this total-heat exchanger also comprises exhaust side bypass channel 26, and this bypass channel 26 is used to guide room air directly to discharge by discharge duct outlet 22.After passing through second exhaust pipe road bullport 25, the room airs that are incorporated into discharge duct 20 by discharge duct inlet 21 flow along exhaust side bypass channel 26, are discharged to outdoor then.For room air being directed to exhaust side bypass channel 26, can bypass valve be set at discharge duct 21 places that enter the mouth, and this kind pattern is referred to as bypass mode.
According to above-mentioned structure, when the temperature difference between room air and the outdoor air and psychrometric difference are very little,, open bypass valve to avoid room air and outdoor air by heat exchange elements as in spring and autumn, can reduce the pressure loss that heat exchange elements causes.Therefore, can reduce to be applied to the load of fan, can realize that power consumption reduces, thereby realize energy-conservation.
But in the control logic of existing technology, have only two kinds of situations of all-pass pattern and bypass mode, and no matter under the sort of pattern, intake is identical with exhaust air rate, can not satisfy the demand of some occasions.As for some occasion such as big Internet bar or the market of flow of the people, need room atmosphere pressure greater than outdoor pressure, and its interior atmospheric pressure is wished less than other local pressure in ground such as kitchen, lavatory, flow into parlor or bedroom to avoid foul atmosphere.
Summary of the invention
The object of the present invention is to provide a kind of can the control room in pressure, improve the total-heat exchanger that user satisfaction increases use experience.
The present invention is achieved through the following technical solutions above-mentioned technical purpose:
A kind of total-heat exchanger comprises being used to guide outdoor air to arrive the steam line of the interior space; Be used to guide room air to arrive outdoor discharge duct; And heat exchange elements, and air supply fan, and exhaust fan, its mode of operation comprises all-pass pattern and bypass mode, it is characterized in that: its mode of operation also comprises barotropic model and negative pressure pattern.
Described barotropic model be the air supply fan rotating speed greater than exhaust fan, described negative pressure pattern is that the air supply fan rotating speed is less than exhaust fan.
Described barotropic model is that air supply fan works in the ultrahigh speed shelves, and exhaust fan is positioned at low or first gear or top gear.
Described barotropic model is that air supply fan works in top gear, and exhaust fan is positioned at low or first gear.
