Technical field
The present invention relates in the ventilation process in house, be used for the heat-exchange ventilating system of heat exchange.
Background technology
Fig. 7 shows the example that is used for traditional heat-exchange ventilating system of heat exchange in the ventilation process in house.
Traditional heat-exchange ventilating system is installed in the space 1 above the ceiling of building office building for example.The unit ventilators 2 of system links to each other with exhaust trunk line 4 with air feed trunk line 3.Opening 3a, the 4a of each trunk line 3,4, so that pass through air feed trunk line 3 with in the outdoor fresh air suction ventilation unit 2 and arrange the air in the unit ventilators 2 to outdoor by exhaust trunk line 4 towards outer openings.
Unit ventilators 2 also links to each other with discharge duct 7 with steam line 6.Steam line 6 links to each other with the gas vent 8 in each house 5, and discharge duct 7 links to each other with the gas feed 9 in each house 5.
As shown in Figure 8, unit ventilators 2 has housing 10, and this housing 10 comprises into latticed a plurality of heat exchanger plates 11, so that form interlaced air supply channel 12 and exhaust passage 13, position.One end of air supply channel 12 links to each other with air feed trunk line 3, and the other end links to each other with steam line 6.One end of exhaust passage 13 links to each other with exhaust trunk line 4, and the other end links to each other with discharge duct 7.
When starting during with fan (not shown) that air feed trunk line 3 links to each other, unit ventilators 2 by air supply channel 12, steam line 6 and gas vents 8 in air feed trunk line 3, the unit ventilators 2 according to priority with in the outdoor air supply house 5.
On the other hand, when starting during with exhaust fan (not shown) that exhaust trunk line 4 links to each other, the air in the house 5 are arranged to outdoor by gas feed 9, discharge duct 7, unit ventilators 2 interior exhaust passage 13 and exhaust trunk lines 4 successively.
When air was supplied with and discharge, the heat exchanger plates 11 by unit ventilators 2 carried out heat exchange.
For example, suppose that summer, outdoor temperature was 35 ℃, and the air-conditioning (not shown) is cooled to 25 ℃ with house 5, when 35 ℃ outdoor airs flowed into the air supply channel 12 of unit ventilators 2, it was flow through 25 ℃ exhaust cooling of exhaust passage 13 in this air supply channel.Like this, the air that is cooled to is to a certain degree infeeded in the house 5.
On the other hand, suppose that winter, outdoor temperature was 5 ℃, and the air-conditioning (not shown) is heated to 20 ℃ with house 5, when 5 ℃ outdoor airs flowed into air supply channel 12, it was flow through 20 ℃ exhaust heating of exhaust passage 13 in this air supply channel.Like this, the air that is heated to is to a certain degree infeeded in the house 5.
Briefly, outdoor air is not directly supplied with, but with the cooling of discharge or add hot-air cool off or heat after resupply.
Above-mentioned heat-exchange ventilating system is designed to like this, and promptly the opening 3a of air feed trunk line 3 is positioned at from the opening 4a of exhaust trunk line 4 position far away as far as possible.Opening 3a and 4a purpose away from each other is drawn in the air feed trunk line 3 from the air that exhaust trunk line 4 is discharged again in order to prevent.In other words, when opening 3a and 4a are close to each other, may be drawn into shortcoming in the air feed trunk line 3 again with producing the air of discharging, for example, when people in a house 5 during smoking, smoke may be fed in other house 5.

Fig. 3 illustrates the view of the special construction of the heat exchanger in air supply unit 17 and exhaust unit 18 32,39 respectively.
For each heat exchanger 32,39, box-like housing 42 has at the inflow entrance 48 of one end with at the flow export 49 of its other end, and comprises a plurality of grids 43 and a plurality of filter 44.
As shown in Figure 4, each grid 43 links to each other upstream trunk line 45 by the heat exchanger tube 47 by a plurality of minor diameters and forms web form with downstream trunk line 46.Upstream trunk line 45, downstream trunk line 46 and heat exchanger tube 47 are formed from a resin and enough flexibilities are arranged.
A plurality of such grids 43 are arranged in parallel, as shown in Figure 3.The upstream trunk line 45 of each grid 43 links to each other with upstream manifolds (header) (not shown), and the downstream trunk line 46 of each grid 43 links to each other with the downstream manifold (not shown).
When fluid was introduced the upstream trunk line 45 of each grid 43 from upstream manifolds, fluid was introduced corresponding downstream trunk line 46 by a plurality of heat exchanger tubes 47.Introducing the fluid of downstream trunk line 46 discharges from downstream manifold.
Each filter 44 shown in Fig. 3 has mesh-structured, the scope of its mesh size be from several millimeter to tens millimeters, thereby allow air or water to flow through.Filter 44 can be made by metal such as stainless steel or synthetic resin, considers thermal conductivity, preferably adopts metal, and considers the deposition that prevents to get rusty and prevent chip, preferably adopts resin.
Before the housing 42 of packing into, a plurality of filters 44 and a plurality of grid 43 superpose with alternating sequence.
By the heat exchanger 32,39 of said structure, air is introduced housings 42 from inflow entrance 48, is cooled the process of filter 44 or heats flowing between heat exchanger tube 47 and flow through then.Then, the air of this cooling or heating is discharged from flow export 49.

As shown in Figure 2, the air feed heat exchanger 32 of design links to each other with 51 by pipeline 50 with exhaust gas heat exchanger 39 in the above described manner.Especially, pipeline 50 makes the downstream manifold of air feed heat exchanger 32 link to each other with the upstream manifolds of exhaust gas heat exchanger 39, and pipeline 51 makes the upstream manifolds of air feed heat exchanger 32 link to each other with the downstream manifold of exhaust gas heat exchanger 39.
Nozzle 53 is sprayed water on exhaust gas heat exchanger 39.The water that sprays is through heat exchanger tube 47 each surface and flow through filter 44 inside, so that flow out downwards, focuses in the returnable then.Pump 54 makes this water circulation.
Carry out the principle of heat recovery by air feed heat exchanger 32 and exhaust gas heat exchanger 39 below with reference to Fig. 5 explanation.
For example, suppose that summer, outdoor temperature was 35 ℃, air-conditioning is cooled to 26 ℃ with house 14,15, and when 35 ℃ outdoor airs flowed into air feed heat exchanger 32, its flowed through this air feed heat exchanger 32 in fluid of this air feed heat exchanger 32 cooled off.At this moment, the temperature that flows through the fluid of air feed heat exchanger 32 is set at 20 ℃, is 28 ℃ thereby can make air feed heat exchanger 32 that the outdoor air that sucks is cooled to temperature.After the heat exchange, the temperature that flows out the fluid of air feed heat exchanger 32 is 33 ℃.
The air that is cooled to 28 ℃ by air feed heat exchanger 32 is supplied with house 14,15, and further being cooled to temperature by air-conditioning then is 26 ℃.
The air that is cooled to 26 ℃ like this in the house 14,15 passes through exhaust gas heat exchanger 39 to outdoor discharge.At this moment, 33 ℃ fluid is introduced exhaust gas heat exchanger 39 from air feed heat exchanger 32.Therefore, the exhaust by 26 ℃ in exhaust gas heat exchanger 39 of 33 ℃ fluid is cooled off.
Water is sprayed onto in the exhaust gas heat exchanger 39 from nozzle 53, and then, water is the defluent while in this exhaust gas heat exchanger, owing to the air that flows through heat exchanger 39 evaporates.Therefore water evaporate, and remove heat of vaporization, thereby the temperature of water is reduced.
In other words, exhaust gas heat exchanger 39 is removed heat of vaporization, thereby further cools off the fluid that flows through in this exhaust gas heat exchanger 39.
As mentioned above, being cooled to temperature is that 20 ℃ fluid flows out in the air feed heat exchanger 32 from exhaust gas heat exchanger 39 by pipeline 51.Then, outdoor air is cooled to temperature is 28 ℃ to 20 ℃ fluid.
And, for example suppose that outdoor temperature is 5 ℃ in the winter time, heater is heated to 25 ℃ with house 14,15, and when 5 ℃ outdoor airs were introduced air feed heat exchanger 32, its flowed through fluid of this air feed heat exchanger 32 heated.At this moment, the temperature that flows into the fluid of air feed heat exchanger 32 is set at 20 ℃, is 15 ℃ thereby allow air feed heat exchanger 32 that outdoor air is heated to temperature.After the heat exchange, the temperature that flows out the fluid of air feed heat exchanger 32 is 18 ℃.
The air that is heated to 15 ℃ by air feed heat exchanger 32 is supplied with house 14,15, and further being cooled to temperature by heater then is 25 ℃.
The air that is heated to 25 ℃ in the house 14,15 passes through exhaust gas heat exchanger 39 to outdoor discharge.At this moment, 18 ℃ fluid is introduced exhaust gas heat exchanger 39 from air feed heat exchanger 32.Therefore, the exhaust of 18 ℃ fluid by 25 ℃ is heated to 20 ℃.
Like this, the fluid that is heated to 20 ℃ is introduced in the air feed heat exchangers 32 from exhaust gas heat exchanger 39 outflows and by pipeline 51.Then, 5 ℃ outdoor air is heated to temperature is 15 ℃ to 20 ℃ fluid.
Should be known in that water is not sprayed onto on the exhaust gas heat exchanger 39 when in the above described manner the house being heated.
As mentioned above, the effect of the heat energy in air that recovery discharges is played in 39 combinations of air feed heat exchanger 32 and exhaust gas heat exchanger from house 14,15.
According to present embodiment, as shown in Figure 1, provide air supply unit 17 and exhaust unit 18 to allow unit 17 and 18 to be arranged to the each interval certain distance separately.In addition, the air inlet 19 of air supply unit 17 directly is opened on the wall 21, and the exhaust outlet 20 of exhaust unit 18 directly is opened on another wall 22.Above-mentioned design does not need to be used for the trunk line of aforementioned conventional example.
Therefore, no any because of the situation of trunk line to the restriction of arrangement under, therefore can make the position each interval of air inlet 19 and exhaust outlet 20 enough far away.Because the abundant interval of air inlet 19 and exhaust outlet 20 is arranged, can obtain very high drafting efficiency.
For each unit, air supply unit 17 comprises air feed heat exchanger 32, and exhaust unit 18 comprises exhaust gas heat exchanger 39, like this, only needs to provide air supply channel 30 or exhaust passage 37.Therefore, two unit 17 and 18 size can both reduce.
Therefore, the restriction of air supply unit 17 or 18 pairs of installation sites of exhaust unit reduces.
Fig. 6 illustrates the combined system of above-mentioned heat-exchange ventilating system and heating/coldplate 55,56.Represent with identical Reference numeral with parts identical among Fig. 1, and omission is to their detailed description.
Heating/ coldplate 55,56 is as the ceiling in house 14,15, and formation like this, and grid 43 promptly shown in Figure 4 is positioned on the radiant panel, and is coated with heat-insulating material.This grid 43 of cold water or hot water supply is so that cooling or heat this radiant panel.The heat radiation of this radiant panel makes each house 14,15 coolings or heating.
In Fig. 6, Reference numeral 57 expression is installed in the Cold water supply device that roof etc. is located, and Reference numeral 58 expressions are installed in the hot water supply device in corner.
Cold water supply device 57 links to each other with the cooler 33 of first heat exchanger 59 and air supply unit 17, so that to they feeding cold waters.
Hot water supply device 58 links to each other with the heater 34 of second heat exchanger 60 and air supply unit 17, so that supply with hot water to them.
Heating/ coldplate 55,56 links to each other with second heat exchanger 60 with this first heat exchanger 59.The cold water of cooling is introduced each heating/ coldplate 55,56 in first heat exchanger 59, and the hot water of heating is introduced each heating/ coldplate 55,56 in second heat exchanger 60.
Valve V links to each other with each pipeline of cold water or hot water being introduced heating/coldplate 55,56.Cold water or hot water all pass through this valve and introduce each heating/ coldplate 55,56.
Should be known in that Cold water supply device 57 can directly link to each other with heating/ coldplate 55,56 with hot water supply device 58, and do not need to insert first heat exchanger 59 and second heat exchanger 60, so that directly with cold water and hot water supply heating/ coldplate 55,56.
Usually, do not introduce bypass channel 61 from the outdoor air that air supply channel 23 flows into, but directly supply with house 14 by discharge 25.
Valve can be arranged in the pipeline so that with Cold water supply supplementary heat exchanger 62, thereby only when using supplementary heat exchanger 62 with Cold water supply supplementary heat exchanger 62.
According to said system, because the fact is when heating/ coldplate 55,56 is used to cool off, 17 pairs of outdoor airs of air supply unit dehumidify, and therefore can prevent to form condensation on heating/coldplate 55,56.Especially, when this heating/ coldplate 55,56 cooling houses 14,15,, will heat/produce condensation on the radiating surface of coldplate 55,56 at this if outdoor humid air is supplied with this heating/coldplate.Therefore, need come by special dehumidification system outdoor air is dehumidified usually.
But, according to system of the present invention, cooler 33 in the air supply unit 17 of packing into and heater 34 are configured for the dehumidifier of outdoor air dehumidifying, and this does not need special dehumidifier system.
And, because the hot water of supplying with the cold water of cooler 33 and supplying with heater 34 is identical with the cold water and the hot water that are used to supply with heating/ coldplate 55,56, so do not need the extra heat source that is used to dehumidify.
Therefore, compare with the situation that has adopted the extra heat source that is used to dehumidify, the one-tenth instinct of whole system reduces.
And the supplementary heat exchanger 62 that is used for house 14 can be operated not simultaneously in the temperature rising ratio in house 14 and other house, like this, can handle this house separately.
In addition, because the thermal source of supplementary heat exchanger 62 comes from the heating/coldplate 55 in the house 14, therefore be easy to it is constructed, and can reduce cost at an easy rate.
In said system, heating/ coldplate 55,56 is used to form ceiling, but they also can be used to form the wall in house.
In said system, supplementary heat exchanger 62 is used to cool off, but it also can be designed to the hot water of accepting to supply with and heat.
