Background technology
Along with the raising of people's living standard, to the also constantly lifting of requirement of resh air requirement, the increase of resh air requirement has caused the increase of air conditioning energy consumption.Simultaneously, most of air-conditioning system is not all used any exhaust air energy recovery mode, causes a large amount of low-grade energies to waste.
At present, for common family and office, indoor pollution is day by day serious, and people mainly come to take a breath to indoor with common exhaust fan now.The shortcoming of this scavenging way is: one, during the broiling summer, in the situation of indoor use air-conditioning, because indoor/outdoor temperature-difference is very large, to indoor air-changing, can have influence on the refrigeration of air-conditioning such as the common exhaust fan of direct use, increase the consumption of the energy; Two, in the winter of cold, because indoor/outdoor temperature-difference is also larger, cause equally the increase of energy consumption.
The utility model content
In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to address the deficiencies of the prior art, a kind of ventilation air interchange system is provided, be mainly used in the two-way ventilation of indoor and outdoor, air inlet and give vent to anger and to carry out heat exchange by the tube wall of middle air pipe, realize recuperation of heat, reduce the consumption of the energy.
For achieving the above object, the utility model provides a kind of ventilation air interchange system, comprising: peripheral breather pipe; Middle air pipe, described middle air pipe are arranged in the described peripheral breather pipe; Blower fan, described blower fan are arranged at an end of middle air pipe and peripheral breather pipe, are used for air-supply, air draft.
Optionally, described peripheral breather pipe and middle air pipe are gapped.
Optionally, be provided with heat exchange fin on the tube wall of described middle air pipe.
Optionally, described heat exchange fin is arranged at tube wall inboard and/or the outside of middle air pipe.
Optionally, in described each breather pipe volume damper is housed.
Optionally, described volume damper is the aperture-type volume damper.
Optionally, in the described middle air pipe filter packing is housed.
Optionally, described middle air pipe and peripheral breather pipe all have the part body to be arranged in the room, and the length of the middle air pipe of this part is greater than the length of peripheral breather pipe.
Compared with prior art, one or several that the utlity model has in following advantage and the beneficial effect is:
1. the middle air pipe of the ventilation air interchange system of an embodiment of the present utility model is arranged in the peripheral breather pipe, is provided with the blower fan of supply and exhaust at an end of middle air pipe and peripheral breather pipe, realizes two-way ventilation.
2. peripheral breather pipe and the middle air pipe of the ventilation air interchange system of an embodiment of the present utility model are gapped, are provided with heat exchange fin on the tube wall of middle air pipe, thereby low-energy consumption falls in the realization recuperation of heat.
3. in the middle air pipe of the ventilation air interchange system of an embodiment of the present utility model filter packing is housed, plays the effect that purifies air.
4. the breather line of the ventilation air interchange system of an embodiment of the present utility model is in the part in room, and the length of middle air pipe is the effective structure of a kind of fresh-air ventilation greater than the length of peripheral breather pipe.
5. the ventilation air interchange system of an embodiment of the present utility model is simple in structure, safe and reliable, and the ventilation structure takes up space little.

The specific embodiment
With specific embodiment the utility model is further described below with reference to accompanying drawings.
The utility model provides a kind of ventilation air interchange system.
As depicted in figs. 1 and 2: the ventilation air interchange system of embodiment of the present utility model, mainly comprise: peripheral breather pipe 2 and middle air pipe 3, middle air pipe 3 is arranged in the peripheral breather pipe 2, and be provided with at an end of two breather pipes be applied to blow, the blower fan 1 of air draft.Blower fan 1 inboard inlet scoop can the suction-chamber in air draft, new wind can be sent in inlet scoop, the outside.The two-way ventilating device that peripheral breather pipe 2 and middle air pipe 3 form is taken a breath to each floor.Alternatively, in peripheral breather pipe 2 and the middle air pipe 3 aperture-type volume damper 9 is housed, regulates when can realize in peripheral breather pipe 2 and the middle air pipe 3 air quantity, air outlet 6 and exhaust outlet 54 carry out two-way ventilation to each layer room.Peripheral breather pipe 2 can be made by metal or nonmetallic materials, and middle air pipe 3 can be made by the good metal material of heat conduction.
The operation principle of ventilation air interchange system is as follows: at first install according to shown in Figure 1, the blower fan 1 of simultaneously air-supply, air draft is arranged at outdoor, start blower fan 1.Like this, outdoor new wind is sent into indoor by middle air pipe 3 and air outlet 6, and indoor exhaust wind is discharged outdoor by exhaust outlet 5 and peripheral breather pipe 2, reach the effect of ventilation.When indoor/outdoor temperature-difference was larger, outdoor new wind and indoor exhaust wind can be carried out heat exchange by tube wall and the fin 7 of middle scavenge trunk 3.Like this, outdoor new wind reclaims the contained heat of indoor exhaust wind through after the heat exchange, avoids ventilation rear because indoor exhaust wind causes thermal loss, avoids increasing extra energy resource consumption.
Alternatively, gapped between described peripheral breather pipe 2 and the middle air pipe 3.
Alternatively, be provided with heat exchange fin 7 on the tube wall of described middle air pipe 3, can accelerate the conversion of heat, thereby reduce the loss of energy.
Alternatively, described heat exchange fin is arranged at tube wall inboard and/or the outside of middle air pipe 3, is conducive to the exchange of heat.
As a kind of optional embodiment of the utility model, in described each breather pipe volume damper 9 is housed, this control valve can be regulated the size of air quantity.
As a kind of optional embodiment of the utility model, described volume damper 9 is the aperture-type volume damper, regulates simultaneously the air quantity in middle air pipe 3 and the peripheral breather pipe 2.
As a kind of optional embodiment of the utility model, in the described middle air pipe 3 filter packing is housed, play the effect that purifies from the outdoor air that sucks in.
As a kind of optional embodiment of the utility model, described middle air pipe 3 and peripheral breather pipe 2 all have the part body to be arranged in the room, and the length of the middle air pipe 3 of this part is greater than the length of peripheral breather pipe 2, thereby avoid discharging from the peripheral breather pipe 2 of the very fast quilt of the outdoor fresh air that sucks in, improved efficient.
Above-described only is better possible embodiments of the present utility model; described embodiment limits scope of patent protection of the present utility model; therefore the equivalent structure done of every utilization specification of the present utility model and accompanying drawing content changes, and in like manner all should be included in the protection domain of the present utility model.
