Abstract

To permit the forming of a comfortable space while saving energy by a method wherein air is sent into a room from the lower part of a room in spite of whether the airflow is warm-air or cold air while the send-out speed of warm-air or cold air is kept at a value lower than a predetermined value. Upon cooling or heating the inside of a room and the like or the interior space of a building, air is sent into the room from the lower part of the room in spite of whether the airflow is of warm-air or cold air. A living zone (a) in the height direction of the interior of the building is defined by the suction port 5 of an air-conditioner provided at the upper part of the air sending port 4 and a zone from the living zone (a) to a ceiling surface 2, positioned above the living zone, is determined so as to be the non-control area of air conditioning. The send-out speed of warm-air or cold air is kept at a value lower than 2m/s substantially. Upon heating, the temperature of heating air is kept at 35 deg.C or lower and preferably at a value lowr than 30 deg.C to a room temperature (22 deg.C) while the temperature of cold air is kept at a temperature higher than 15 deg.C and preferably at a value higher than 20 deg.C to a room temperature (26 deg.C) upon cooling. By this method, a comfortable space, in which a temperature difference between the upper part and the lower part of the inside of a room is small, can be formed while saving energy.

Description

Following discharge, upper absorbing air conditioning method

The present invention relates to a kind of under the situation of cool-air feed or heating installation all be discharge down, on the air conditioning mode of suction-type, particularly about a kind of can be under energy-conservation prerequisite, form indoor about the new-type air conditioning mode of the little comfortable space of temperature difference.

About air conditioning mode, the method for myriad of well known was just arranged in the past, its main purpose all is in order to form comfortable space, i.e. the uniform space of formation temperature.All be the installation method of position, outlet in the past or how control and propose all ways from the aspects such as air-flow that outlet is discharged and reach this purpose from outlet.

Generally, be trapped in ground cold air,, therefore, when heating gas,, normally take the mode of discharge on the ground for cold air is blown away owing to the temperature low-gravity is stablized on the ground greatly.In other words,, must take ground to discharge in order to remove above-mentioned cold air, or ground mode of heating (heating equipment under the floor).So-called thermal carpet mode with energising heating carpet is considered to effective method with regard to its connotation.

In addition, for dwelling house etc. indoor use the heat-pump-type heating and cooling equipment more widely popularized, be that the air conditioner main body is installed on the metope of top, room, when heating gas, heating installation is vertically discharged below machine downwards.Yet can not blow away being trapped in ground cold air in this way, the degree of air-conditioning mostly can not be satisfactory.Particularly because coldblast that blows from the window that faces outside atmosphere and metope or the airtight slit wind that does not sternly cause of window frame etc. when causing air to become low temperature, this cold air becomes greatly often delay on the ground because of proportion.

In addition, above-mentioned heat-pump-type changes in temperature gas supply method generally is the discharge direction that changes air-flow when cool-air feed, it is discharged to horizontal direction, but this is the method that sticks to very much technology general knowledge in the past, can not eliminate above-mentioned deficiency.

Though when cool-air feed, the situation of being discharged cold air by ground is less, this mode of rare employing, in this case, consider to arrive distance, wind speed is set in about 3～4m/s.In addition, the practical situation of above-mentioned heat-pump-type on-wall type heating and cooling equipment is to adjust outlet when cool-air feed, it is discharged to horizontal direction, and concerning grounding, when cool-air feed, take the method for upwards being discharged by machine top.

Illustrate in passing, when cool-air feed or heating installation, discharge the different situation of temperature of air in addition, thereby those initiatively change the position of discharge, suction inlet, so that indoor method of carrying out air-conditioning equably also known (opening flat 3-279726 communique etc. with the spy real public clear 49-30002 number referring to Japan Patent).But said each method is not all avoided shortcomings such as complex structure, use inconvenience.

As above described in detail when handling according to technology general knowledge in the past, generally is when supplying with heating installation like that, makes heating installation by discharging near ground or the ground, and on the other hand, the cold air in the time of making cool-air feed is as far as possible discharged from indoor top.

According to above investigation, the inventor has investigated prior art, the invention of finding special fair 1-57259 communique record has proposed following motion, the intention that is this mode is: be when supplying with heating installation it to be discharged by top, suck by the bottom, and carry out air without electric fan etc. and stir, make heating installation at indoor progressively savings, thereby make the whole indoor heating installation that is full of.But, must it should be noted that when the cool-air feed for this mode, opposite when making its drain position and supplying with heating installation, make cold air by discharging near the ground, near ceiling, suck.This mode good and bad let us not go into the question now and since this mode when taking a breath at every turn per minute need 0.3～3 times heating installation or cold air of chamber volume, thereby also be not satisfactory way from energy-conservation viewpoint.

The present invention be directed to when supplying with changes in temperature gas, how to realize comfortableness and the energy-conservation result who makes great efforts to study effectively, with the diverse design of method in the past under, develop following mode.

Be trend and the intrinsic character of building that the present invention utilizes heating installation or cold air energetically, and do not carry out air as far as possible and stir, discharge slowly under the state of wind speed than previous methods in maintenance, no matter hot blast or cold wind are all taked from the bottom it to be discharged, suck from top, wind speed when keep discharging simultaneously and only forms comfortable space to the residential area of the short transverse of being divided by above-mentioned suction inlet below 2m/s, thereby can save energy.

As everyone knows, because the heating installation light specific gravity, being discharged to indoor hot blast becomes ascending air, often be stuck on the roof in or the ceiling face near, on the other hand, owing to cold air with above-mentioned opposite, than great, be trapped near the ground more.Therefore, stirred room air by electric fan etc. in the past, or the wind speed that outlet is discharged was brought up to about 3～4m/s, be in harmonious proportion in the hope of obtaining uniform air as far as possible.

In contrast, the present invention has changed the design of above-mentioned previous methods, because the intrinsic property of building, promptly owing to be commonly referred to as interior zone (referring to (III) of Fig. 8 (the B)) lining of inboard of the indoor surrounding space (referring to (II) of Fig. 8 (B)) of neighboring area in the sector, be typically provided with lighting apparatus and/or office machinery, heaters such as while human body are also influential to indoor temperature, therefore, can regard above-mentioned interior zone as a wholely, see a kind of heating region as.Utilize this character in the present invention energetically, find when supplying with heating installation, mainly the cold air of above-mentioned neighboring area is blown away and get final product, therefore, the discharge wind speed is remained on below the 2m/s substantially.Even under the situation that above-mentioned such low speed is discharged, also can near outlet, therefore produce and stir air, also can make temperature even thus.

The outlet that the application will be arranged on air conditioner below is arranged on below the 1000mm, and blows out cold wind and hot blast has special meaning from it.At the heating installation state, the hot blast that blows out near the below outlet the ground does not rise to the ceiling direction, but forms the heating installation layer near the floor in the scope of whole ground fast and widely.Produce temporary transient reverse phenomenon that the layer of cold gas of floor boosted by the heating installation layer, usually, near flat surfaces such as floor or wall surfaces and the air communication that blows out is crossed section Anda (koanda) effect, though can be attached on this flat surfaces and flow, but in this application, because having a narrow range of temperature between the hot blast temperature that begins to make room air (cold air) temperature at warm initial stage and blow out is so buoyancy is also little comparatively speaking.In addition, owing to discharge the low speed of wind speed below 2.0m/s, hot blast just is attached on the floor.That is, bigger to the adhesive force of floor than the buoyancy of hot blast, so hot blast can directly not rise to the top grid bearing.

Discharging wind speed is one of feature of the application very slowly.When outlet blows out lentamente,, the air-flow of the air of discharging can not blow afloat to the ceiling direction even running into barrier yet.Owing to contact lentamente, can make a circulation in the horizontal direction to outflank and diffuse to whole floor scope with barrier.From the existing mode that ceiling blows out, " make the wind speed of air quantity in-position " (terminal velocity) though can be 0.25m/s at the center, in fact the center is set in 0.5m/s during heating installation state etc.Therefore, the wind speed that the present invention discharges from air conditioner is set in below the 2.0m/s, and 2.0m/s～0.6m/s particularly makes indoorly can not stir up a cloud of dust.

On the other hand, when cool-air feed, identical during also with supply heating installation, take down to discharge, cold air at this moment is also same as described above to remain on below the 2m/s cold wind of discharge, because the relation of proportion, further on the ground gradually diffusion go down, temperature height and the little air of proportion makes progress from the bottom then, thus form the same comfortable space that does not have the temperature inequality.

Another feature of the present invention is when supplying with heating installation or cold air, not to comprise that near the ceiling indoor Zone Full heats at large or lowers the temperature resembling in the past, carry out air in the residential area (referring to (I) of Fig. 8 (A)) in short transverse and be in harmonious proportion and be only limited to, in other words, in the drawings with near the ceiling shown in the label (IV), be not carry out changes in temperature controlled atmosphere joint as the zone beyond the air mediation object.When dividing above-mentioned residential area, also can be the suction inlet of cold air or heating installation as the device of dividing.In other words, by the determined height of the rising wood of above-mentioned suction inlet apart from ground just be called heavy Nogata to the residential area.In addition, the notion of said residential area not only is meant the living space with artificial object here, and is meant and can uses the present invention, and plant or animal are carried out the control height that air is in harmonious proportion as object.

In addition, so-called air-conditioning equipment is meant that institutes such as comprising heating installation special machine, cold air special machine and changes in temperature gas dual-purpose machine is useful on the machine that air is in harmonious proportion, so-called bottom is discharged and is meant and comprises the situation that outlet is set on the ground, and near the vertical plane being arranged in ground is to any of the situation of discharging from the ground, upper strata of double floor like that shown in situation of discharging on the ground and the aftermentioned embodiment.

More particularly, the present invention is: 1. the residential area height with aforesaid vertical direction typically remains on ground 800～2, in the scope of 200mm, 2. all be that outlet with heating installation or cold air is set on the ground 1 under the situation of cool-air feed or heating installation, below the 000mm, 3. fix on the discharge wind speed of heating installation or cold air below the 2.0m/s substantially again, 4. in addition, when supplying with heating installation, the temperature of heating installation itself is remained on below 35 ℃, preferably remain on and arrive in room temperature (22 ℃) scope, 5. on the other hand below 30 ℃, when cool-air feed, the temperature of cold air is remained on more than 15 ℃, preferably remain on and arrive in the scope of room temperature (26 ℃), thus more than 20 ℃, compare with method in the past, the method minimum with energy loss just can realize not having the uneven temperature comfortable space.

Below, with reference to accompanying drawing embodiments of the invention are described.

Fig. 8 (A), (B) are the key diagrams for conceptual illustration technical conceive of the present invention, among the figure, the exterior wall, 2 of label 1 expression building is that ceiling face, 3 is ground, 4 outlets for heating installation or cold air, outlet is arranged on the position also lower than suction inlet, can be set directly on the ground, or be arranged on the scope certain apart from ground, for example apart from the height on ground 1, on the side of 000mm with interior interior metope or post.In addition, label 5 is arranged on the heating installation on the metope in the room or the suction inlet of cold air, installation site about this suction inlet, be typically it is defined in the above 800-2 in ground, in the scope of 200mm, thus between the installation site and ceiling face of above-mentioned suction inlet, the territory, noncontrolled area in the time of can setting air-conditioning (referring to (IV) described later).

Illustrate in passing, usually, above-mentioned lower limit 800mm be according to abundant covering accumbency in bed state altitude range and decide, higher limit 2,200mm decides according to the scope that covers common body ' s stature, by embodiment described later also as can be known, be object when setting air conditioning area with the animal beyond plant or the people, need not stick to above-mentioned numerical value.

As mentioned above, the invention is characterized in: do not resemble the previous method changes in temperature gas is generally supplied with in inside, whole room, and 3 tops, ground, the residential area (I) of the vertical direction of being divided by above-mentioned suction inlet 5 is set at air conditioning area, by from air conditioning area, the space (IV) between above-mentioned suction inlet 5 and the ceiling face 2 being foreclosed energetically, thereby, can save the energy, raise the efficiency.

Have again, in Fig. 8 (B), be meant the indoor surrounding space that is subjected to the building that outside meteorological condition influences by exterior wall, window etc. with the neighboring area shown in the label (II), as shown in the figure, many usually fingers 5, the width about 000mm, but this numerical value does not have special significance.In other words in the present invention, it only indicates is meaning near the surrounding space of wall face, in addition, the inner space that is surrounded with this surrounding space (II) as interior zone (referring to label (III)).

In addition, shown in Fig. 8 (B), for the present invention, when the cold air special machine 6 in the use air-conditioning equipment, it can be arranged on the boundary vicinity of above-mentioned interior zone (III), and when using warm air-cooling system or heating installation special machine 7, it can be arranged in the zone of neighboring area (II), promptly near the inboard of exterior wall 1.As everyone knows, this is owing to mainly be to occur in external wall structure position such as window with the heat transmission in the building external world, be partly to be flowed into by exterior wall at summer fever generally, and heat flows out in the winter time.Therefore, air-conditioning equipment is arranged on and faces exterior wall place efficient height, if when being only limited to the cold air special machine, preferably it is arranged in interior zone (III) zone.As previously mentioned, this is owing in interior zone, be provided with illumination and office machine, also has heaters such as human body simultaneously, can be considered a kind of heating region.In other words, hot blast is owing to light specific gravity becomes ascending air, and the distance of process is shorter than cold wind when interior zone is discharged, and it is such as mentioned above, this zone can be considered heating region in fact again, therefore, can not resemble and expect the heating installation diffusion that caused by difference in specific gravity the cold air.

Below, with reference to Fig. 1～Fig. 4, specifically describe the present invention by an embodiment, Fig. 1～Fig. 4 be expression the air conditioner 7a that includes fan coil be installed in exterior wall 1 on example on the metope of set window 10 adjacency.When in vertical plane, studying this example, then as indicated in Fig. 2, under cool-air feed or heating installation situation, all be to use same air conditioner 7a, discharge hot blast or cold wind by the outlet 4 that is positioned at the bottom, on the other hand, as mentioned above, be to pass through as preferred enforcement state apart from ground 800～2, the suction inlet 5 of 200mm scope inner opening makes room air circulation.In Fig. 1, be drainage pipeline with the member shown in the label 7b, label 7c is the hot and cold water pipeline.Also have, label 8 is a division wall, and label 9 is for to constitute the floor on ground upstairs, the 11st, and door.

Below, according to Fig. 3～4, further specifically describe the example that use in the hydro-thermal source.In these figure, label 20 is an off-premises station, and 21 is refrigerant tubing, and 22 is compressor, and 23 is heat pump, and 24 is heat exchanger, and 25 is pump, with these machines the hot and cold water of adjusting to set point of temperature is fed to be installed in the indoor air conditioner.The details of the above-mentioned air conditioner 7a of Fig. 4 (A)～(D) expression, the section of the blade 12 on the suction inlet 5 is shown in Fig. 4 (C).The direction of the blade 12 on the suction inlet 5 makes longitudinal and transverse all harmless, but the direction of the blade 13 on the outlet 4, can make it can be vacillated now to the left, now to the right shown in Fig. 4 (D), so that can change wind direction.Label 14 expression fans among Fig. 4,15 expression access holes, 16 expression cowling panels.

In addition, as preferred embodiment, as indicated in Fig. 4, can be respectively the open height of above-mentioned outlet 4 and suction inlet 5 be remained in 1/2 the scope that is not more than the air conditioning area height H.

Then, just the cool-air feed method of the glass chamber shown in Fig. 5～6 is illustrated.Example shown in this figure is that expression must be controlled a kind of greenhouse that the plant culture of room temperature is used, among the figure, label 30 is the glass roofs that often can accept sunshine S, the 31st, and the skylight of ventilation usefulness, the 32nd, be used to place the high desk-top mounting plate of flowerpot, which is provided with many passages 33.In addition, below this mounting plate 32, be provided with the ventilating duct 34 that is used to induce cold wind or hot blast as shown in the reference numeral 34, this ventilating duct and above-mentioned mounting plate are taken together, just constitute a kind of double-layer ground.Part shown in the label 35 is the used passages of greenhouse management personnel.

In the present invention, because the principle of proportion, blow out air with proper temperature humidity is near the upwards diffusion floor, form the temperature of layering thereafter, floor (outlet) and be about 2.0 ℃～3.0 ℃ with the temperature difference of the highest (suction inlet) of the residential area of artificial object, indoor environment temperature also becomes thermal stratification.Since evenly whole, so be very comfortable environment.Make fresh air after single treatment, import air conditioner, near the floor from below blow out.In addition, the air that heats up owing to indoor human body or the heat that sends of heating machine and utilized upwelling to rise by the air that smog, dust polluted of tobacco, under the situation of not fail temperature layering, separate fully, utilize exhaust blower from the territory, noncontrolled area and discharge.Skylight 31,31 exhausts from regulating aperture in Fig. 6 are to utilize the blast pipe (not shown) in being configured in above the grid of top and arrange to the outside in Fig. 2～4 and Fig. 8.

As shown in the figure, as an example, inboard in above-mentioned ventilating duct part 34, offer the heating installation of the heating and cooling equipment 7a that is provided with along the wall face in greenhouse or the outlet 4 of cold air, on the other hand, as described above, the meaning that the air conditioning area that highly has the division vertical direction is set of the suction inlet 5 of above-mentioned heating and cooling equipment 7a.Therefore, in this example, determine the height that is provided with of above-mentioned suction inlet 5 accordingly with the height of those plants that must in the greenhouse, cultivate.Illustrate in passing that the air-flow that is flowed out by above-mentioned outlet 4 is through behind the ventilating duct 34, promptly by being arranged on passage 33 on the mounting plate 32 to indoor discharge.Therefore,, must accelerate the wind speed of this outlet 4, for example can be taken as 4m/s in order to ensure air quantity.On the other hand, set several times of discharge area of above-mentioned outlet 4 for by the aperture area that will be arranged on the passage 33 on the above-mentioned mounting plate 32, just can easily remain on the wind speed of discharging below the 0.5m/s from the mounting plate.Like this, just can wind speed not maintained plant is produced in the dysgenic scope.

Like this, need sunshine, but temperature must remain on 30 ℃ again with under the inferior situation, can obtain remarkable result with the present invention plant.Particularly because the greenhouse (glass chamber) in summer mostly externally more than the temperature, therefore, must be with very big energy to its cool-air feed, if just at this moment utilizing the present invention for the above reasons as can be known is effectively really, and, because the foregoing description makes air-flow directly not contact plant, be provided with again and put the mounting plate that flowerpot is used, and, therefore, can not injure plant by its underpart discharge cold air yet.

Fig. 7 (A), (B) expression are used for the present invention an example of the air-conditioning of factory floor space.Among the figure, the large space in the label 40 expression factories, the enclosure wall 41 that has drawn idle call is set in the segment space of this large space is with the situation that stops air to move.Label 42 among this figure is arranged on the machine of the regulation in the factory, and the 43rd, the operating personnel of the operation or the above-mentioned machine that turns round, the 44th, material storing place, the 45th, Workpiece storage ground, the 46th, gateway.In the factory that constitutes like this, in the space, when supplying with heating installation, can prevent inflow from cold air on every side; When cool-air feed, can prevent the diffusion of cold air.Particularly when cool-air feed, compare, can improve air-cooling system efficient extraordinarily with local cooler commonly used at present.

By each above-mentioned embodiment as can be known, the present invention has following feature, and produces all effects thus, that is:

(1) can be limited to the residential area that is positioned at below ceiling or the deck in the scope that will carry out air-conditioning on the short transverse, and can divide its scope of setting on one's own initiative by the suction inlet of air-conditioning equipment.In illustrated each embodiment, the zone shown in the label (I) is the residential area, will be positioned at the zone (IV) of its top, is provided with as high-temperature area, and the desired energy resource consumption of air-conditioning is reduced.In addition, because the hot gas of light specific gravity makes this zone become high temperature near being full of ceiling.Like this, the present invention just with the sort of different to comprising that the mode of air-conditioning is generally carried out near the ceiling face whole indoor in the past, can save energy.

(2) no matter under the situation of cool-air feed or heating installation, all be that the velocity of discharge with hot blast or cold wind remains on below the 2.0m/s, with the sort of in the past the velocity of discharge about 3～4m/s is compared as the mode that benchmark carries out air-conditioning, wind speed is obviously weakened, also can produce energy-conservation effect with regard to this point.In other words, owing to strengthen the discharge wind speed of cold air or heating installation not resembling in the past, do not need to use fan etc. to carry out room air again and stir, so energy resource consumption is few.

(3), mainly be the air diffusion that utilizes the difference in specific gravity because of cold air to cause, from the following air-conditioning that upwards carries out because when cool-air feed; On the other hand, main when fully using the heating region of interior of building when supplying with heating installation only to neighboring area supply heating installation, therefore, can reduce the discharge wind speed.In addition, do not adopt 15 ℃ low temperature the discharge temperature during cool-air feed does not also need to resemble in the past, it is got final product about 23～25 ℃, this also is energy-conservation from thermal source.

(4) in addition, when supplying with heating installation, make temperature, the temperature difference of comparing with the environment temperature around the air-conditioning equipment is got into below 10 ℃, can carry out Air mixing energetically than low with contact.And method in the past is that temperature difference is remained on about 15～40 ℃, and compare on every side, owing to be in high temperature, thereby be difficult for carrying out Air mixing, energy-conservation effect is also just less.

(5) as mentioned above, because the present invention has dwindled temperature difference, promoted Air mixing, therefore, when for example temperature is 10 ℃ around, discharge temperature can be set for 20 ℃, during 15 ℃ of environment temperature, discharge temperature is set at 25 ℃, this also generation effect effectively aspect energy-conservation.

As explained in more detail, because in the present invention, no matter at cool-air feed or heating installation Situation under, be not make whole indoor air adjustment and, the residence that short transverse is limited just The specific region in territory, settlement is held in comfort temperature, takes under given conditions the bottom to discharge, Top sucks, and therefore, this point is very clearly, i.e. less of the situation of non-uniform temperature not only Give birth to, and from energy-conservation viewpoint, also can produce epoch-making effect.

1) as mentioned above, the present invention can be only to the zone of necessity (to people's cool-air feed or heating installation The residential area) carries out air-conditioning.

2) owing to only heating installation or cold air are directly supplied with in the zone of necessity, action is fast, thereby arrives The time of a home from home of regulation is short.

3) can near the temperature (temperature that temperature difference is little) of set point of temperature as supplying temperature.

4) above-mentioned every also suitable for thermal source.

Because the present invention makes top become high temperature, the bottom becomes low temperature, can not make the sky of ceiling face Gas drops to the bottom, therefore, can prevent that the contaminated air of the risings such as cigarette of cigarette from sneaking into the residential area In, see it also is resultful from sanitation point.

Additional disclosure when the season of summer and winter conversion, does not need to carry out windscreen with the present invention once again With work such as direction blade changes, therefore simple to operate, easy to use.
