Abstract

The utility model relates to an automatic counterflow type indoor ventilator and environmental protection equipment for cleaning the indoor air. An air inlet valve, an air distributing front header, an air heat exchanger and an air distributing back header. The air inlet chamber and the air outlet chamber of the air distributing front header are connected with the air inlet valve, the air inlet pipe bundle of the air heat exchanger and the air outlet pipe bundle of the air heat exchanger. The air outlet opening and the inner air outlet passage of the air outlet valve arrangedtled on the indoor wall are connected with the air outlet pipe bundle of the air heat exchanger through the air distributing back header. The air filter which is arrangedtled on the outdoor and the outer air outlet pipes are separately connected with the air inlet valve and the air outlet chamber of the air distributing front header. The air descending opening is arranged on the lower part of the air inlet pipe bundle. The ventilator can automatic accomplish the air exchanging work. The structure is simple, the usage is conveniente, the quality and the effect of the air exchanging are high, the heat loss is small and the energy sources are saved.

Description

Automatic reverse-flow indoor ventilator unit

Technical field

The utility model relates to environmental protection equipment, is suitable for mainly that air and outdoor air exchange use voluntarily in the room.

Background technology

The environment space that indoor is human work, study, the inhabitation rest time of staying is the longest and seal, do not carry out the room ventilation ventilation for a long time, harmful substance in the room air and suspended particulate, even bacterial virus all can gather existence in a large number, and human body health is brought very big influence and harm.Especially at the northern China cold district, winter is very long, and indoor winter protection is airtight, and IAQ is poorer, and problem is even more serious, and contradiction is more outstanding.At present, northern area resident in winter adopts small-sized transom window draft type, because its area is little, and inlet, outlet finish by this window, and time of exchanging gas is long, and scavenging efficiency is low; In addition, be Cryogenic air from outdoor air in the direct inlet chamber of transom window, reduced indoor temperature significantly, cause thermal loss.Air regulator only can be finished the indoor temperature adjustment, can not realize that air quality regulates, and this device also needs driven by power, and operating cost is higher, is subjected to the influence of supply of electric power simultaneously.

Summary of the invention

The purpose of this utility model is exactly the problem and shortage that exists at prior art, designing provides a kind of power source that need not to carry out the automatic reverse-flow indoor ventilator unit that room air exchanges voluntarily by the high efficiency high-quality, reaches the purpose of the conservation of power energy, maintenance indoor temperature, minimizing thermal loss, raising ventilation quality and efficient.

Basic design of the present utility model is, on indoor ceiling, install air intake valve, distribution front header, air heat exchanger and distribution back header, the inlet chamber of distribution front header is communicated with the air inlet tube bank of air intake valve and air heat exchanger, the discharge chamber and the distribution back header of air heat exchanger exhaust tube bank two ends and distribution front header are connected, and are fitted in outdoor air cleaner and utilize air inlet to communicate with air intake valve; The interior exhaust passage that is fitted on the indoor interior walls communicates with the distribution back header, is provided with the gas outlet in lower end, interior exhaust passage, and drain tap is configured in the interior exhaust passage; Being fitted in outdoor outer exhaust passage is communicated with the discharge chamber of distribution front header; On the lower surface of air heat exchanger, be provided with the sending down abnormally ascending mouth that the air inlet tube bank is connected with the interior space, so far constitute automatic reverse-flow indoor ventilator unit.

The utility model need not any power source, utilize air reverse flow and heat exchange principle, finish indoor and outdoor air heat exchange and indoor air-changing operation voluntarily, have simple in structure, with low cost, energy savings, scavenging efficiency height, ventilation quality is good, room temperature reduces less, indoor temperature characteristics even, easy to use.

The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of automatic reverse-flow indoor ventilator unit, on the indoor ceiling from indoor external wall to installing air intake valve 4, distribution front header 5, air heat exchanger 6 and distribution back header 7 between the interior walls successively, the inlet chamber two ends of its distribution front header 5 are communicated with the air inlet tube bank 11 of air intake valve 4 and air heat exchanger 6 respectively, the exhaust of air heat exchanger 6 is restrained 12 two ends and is connected with the discharge chamber and the distribution back header 7 of distribution front header 5 respectively, joins solid air cleaner 2 on outdoor body of wall and communicates with air intake valve 4 by the air inlet on the body of wall 1; On indoor interior walls, be positioned at distribution back header 7 bottoms and establish the exhaust passage 8 that dress communicates with distribution back header 7, between 8 lower ends, interior exhaust passage and flooring, locate to be provided with gas outlet 10, in being configured in, drain tap 9 in the exhaust passage 8, is positioned at 10 tops, gas outlet; Outer exhaust passage 3 is fitted in outdoor, and this outer exhaust passage 3 is communicated with the discharge chamber of distribution front header 5; On air heat exchanger 6 lower surfaces, be provided with the air inlet tube bank 11 sending down abnormally ascending mouths 13 that are connected with the interior space.

When ventilation is used, open air intake valve 4 and drain tap 9, outdoor clean air is in air cleaner 2, air inlet 1, air intake valve 4, distribution front header 5 inlet chambers enter the air inlet tube bank 11 of air heat exchanger 6; Indoor foul atmosphere is in gas outlet 10, drain tap 9, interior exhaust passage 8, distribution back header 7 enter the exhaust tube bank 12 of air heat exchanger 6; After the heat exchange of cold and hot air, the fresh airs in the air inlet tube bank 11 flow in the rooms from sending down abnormally ascending mouth 13 in carrying out inlet and

outlet tube bank

11 and 12, the foul atmosphere in the exhaust tube bank 12 through the discharge chamber of distribution front header 5 with outside 3 discharges of exhaust passage outdoor.In the ventilation process, form negative pressuren zone under the suction of exhaust passage 3 outside near the gas outlet 10, fresh air is flowed downwards in sending down abnormally ascending mouth 13 inlet chambers and from the top, become the automatic reverse flow mode of air, finish room ventilation ventilation work continuously, and make indoor temperature even.
