Description
[technical field]
The present invention relates to new air heat-exchange system for building, specifically relate to make the indoor air ventilation of building to upgrade, and the new air heat-exchange system for building that the hot gas in the building wall interlayer is carried out heat exchange.
[background technology]
The ventilation heat exchange mode of existing building has:
1, the ventilation heat exchange of windowing: but this most original the most direct vented exhaust method obviously is inadvisable and drawback is heavy.The draft of windowing blindness, chaotic air-flow may be brought the peculiar smell in toilet and kitchen into parlor and bedroom, and carries a large amount of dust secretly, also can't avoid noise pollution when influencing the indoor cleaning health.In addition, windowing when using the Cooling and Heat Source facility and can cause energy waste, obviously is worthless in the modern society of this exquisite energy conservation.
2, use the ventilation fan heat exchange: though the instantaneous exhaust air rate of traditional ventilation fan is big, can get rid of indoor peculiar smell continuously, the time duty of closing when opening can not continue ventilation, and when no new wind introducing port, exhaust resistance increases, and effect is had a greatly reduced quality.In addition, traditional ventilation fan is along with the growth of service time, and noise problem can constantly increase the weight of, and machine itself is fragile, follow-up maintenance cost cost height.
3, small-sized residential central air conditioning heat exchange: can't fully exchange with outdoor air though it takes back the air port, because there is not air draft, so new wind is difficult to send at barotropic field, though slightly new wind can not thoroughly improve IAQ, foul atmosphere can't be discharged outdoor rapidly.
The room ventilation heat-exchange method of above-mentioned various buildings, the heat exchange weak effect that has, the cost height that has, the needs that have increase the equipment of other highly energy-consuming in addition, can not realize the purpose of energy-saving and emission-reduction, and the noise that has is big.
[summary of the invention]

[specific embodiment]
New air heat-exchange system for building, this building comprises a plurality of rooms, wherein has and the extraneous room that is separated by, and this new air heat-exchange system comprises air-supply arrangement 1, and described air-supply arrangement 1 is a blower fan; The escape pipe 11 of air-supply arrangement 1 communicates with the top in each room of this building respectively; The exterior wall in the room that is separated by with the external world of described this building is provided with heat transfer space interlayer 2, and a side of heat transfer space interlayer 2 is connected with house interior by exhaust vent 21; The opposite side of heat transfer space interlayer 2 is connected with the external world by vent 22; Described exhaust vent 21 is arranged on the inboard of exterior wall, and described vent 22 is arranged on the outside of exterior wall.Described exhaust vent 21 and vent 22 are arranged on the differing heights on the exterior wall.
As shown in Figure 2, described exterior wall comprise interior walls 200, external wall 201, and connect interior walls 200 and external wall 201 be connected brick 202, described heat transfer space interlayer 2 is made of interior walls 200 and external wall 201, described exhaust vent 21 is arranged on the interior walls 200, and described vent 22 is arranged on the external wall 201.
The quantity of exhaust vent 21 is one, and it is arranged on overhead high 0.5-2.5 rice.The quantity of vent 22 is 1-2, and it is arranged on overhead high 0.3-0.6 rice.
When vent 22 was arranged on overhead high 3.2 meters, the quantity of vent 22 was 1; When vent 22 was arranged on overhead high 0.3 meter, the quantity of vent 22 was 2.
For making the vent air interbed of exterior wall that ventilation effect preferably be arranged, take away outdoor part heat to indoor transmission, need externally analyze within the walls by the position and the area in side air-out mouth, outboard row air port.By following embodiment, utilize the mobile of Fluid Mechanics Computation (CFD) software heat exchanging space interlayer 2 and carry out computational analysis with the heat transfer of body of wall.Wherein the thickness of the interior walls 200 of exterior wall and external wall 201 is 60-100mm.
The air outlet size is 480mm * 53mm * 60-100mm, and the air outlet position is arranged on liftoff 1.5m, and the size of exhaust outlet is 240mm * 53mm * 60-100mm; The quantity of exhaust outlet is 2, and one of them exhaust outlet is arranged on liftoff high 0.3m place, and another exhaust outlet is arranged on liftoff high 3.2m place.In the case, air-flow flows into the body of wall interbed with the average speed of 0.36m/s from inboard air outlet, and behind the wall 201, air-flow is divided into two strands of air-flows up and down outside running into.The air-flow that makes progress along wall wherein, air velocity decays to zero gradually from 0.2m/s, and the air-flow that flows downward is about 0.36m/s, air-flow is after running into ground, be divided into two strands, last under the effect of hot pressing, air-flow flows out from the exhaust outlet 22 of the top speed with 0.82m/s.
Because the setting of wall outer side top exhaust outlet 22, make air-flow increase in the zone of action of body of wall upper area heat transfer space interlayer 2, air velocity is between 0.12～0.2m/s, have only two corners, heat transfer space interlayer 2 tops because far away from top exhaust outlet 22, it is the poorest that air flows, and remains static.Wall body area air current flow below exhaust outlet 22 positions is better, and bigger near the wind speed in air outlet 21, exhaust outlet 22 zones, between 0.3～0.4m/s, other regional wind speed are 0.1～0.2m/s, have increased the heat convection effect in heat exchange space greatly.
Therefore the ratio at exterior wall room ventilation mouth and exterior wall outside exhaust outlet number is 1: 3,1 ventilating opening is set on the external wall 201 of terrain clearance 3.2m place exterior wall, on the external wall 201 of liftoff 0.3m place exterior wall 2 ventilating openings are set, and the suggestion of the area of each exterior wall outdoor ventilation mouth is 240mm * 53mm * 60-100mm.
Heat transfer space interlayer 2 since with medial and lateral building block heat exchange, take away the part heat, make the temperature reduction of outer inner wall.Exterior wall internal face maximum temperature is 34.93～34.95 ℃, satisfies the requirement of " code for thermal design of civil buildings " (GB 50176-93).
