Description

[Detailed description of the invention]

The present invention relates to an interior air conditioning system that can handle the heat load of a perimeter zone and at the same time reduce the loss of thermal energy and achieve effective utilization. As is well known, as an air conditioner attached to a medium- to large-scale general building (for example, an office building), as shown in Figure 1, an interior air conditioner, which corresponds to the air conditioning process for interior zone a, is used. Equipment (air conditioner, etc.) b and perimeter zone c
There is a perimeter air conditioner (such as a fan coil unit) d that performs air conditioning processing, and generally both the interior air conditioner b and the perimeter air conditioner d are installed together. This is because in an air conditioner that serves both interior zone a and perimeter zone c, the heat load and its fluctuations in perimeter zone c are large, and if left as is, this will not only affect perimeter zone c, but also
This also affects zone a, deteriorating the air conditioning function, so as a workaround, a perimeter air conditioner d dedicated to perimeter zone c is installed. There are various factors contributing to the heat load in the perimeter zone c, but most of the heat load is occupied by solar radiation from the outer wall window glass and heat passing through. As a direct measure against solar radiation and through-flow heat, measures are taken to reduce the reflection of solar radiation through the use of blinds, etc., but in general, no measures have been taken to prevent through-flow heat. In special cases, double-glazed glass is used. In special cases, reflective glass may be used to protect against solar radiation.
The role of the perimeter air conditioner d is to reduce the heat load that cannot be handled by the above-mentioned direct methods.
Processing is performed within perimeter zone c without affecting zone a. To briefly explain the illustrated interior air conditioner b, the outside air taken in through the outside air duct f by the operation of the blower e is purified when it passes through the filter g, and then when it passes through the cold/hot water coil h. The temperature is adjusted to the set temperature, and the air is introduced into the living room l through a plurality of blowing slots k provided in the ceiling wall j via the blower e and the air supply duct i. The air supply introduced into living room l is
The air flows inside the air, flows into the return air duct n through the exhaust slot m provided in the ceiling wall j, and is exhausted to the outside via the exhaust duct o. The supply air flowing into the living room l from the blow-off slot k and flowing inside the living room l mixes with the air in the living room l while flowing and exchanges heat, thereby achieving air conditioning in the interior zone a.
On the other hand, in the perimeter air conditioner d, air conditioning in the perimeter zone c is achieved by extracting cold and hot heat from cold and hot water flowing through the cold and hot water pipe p in the fan coil unit q. In addition, in the figure, r is an air supply damper, s is an exhaust damper, t is a blind, and u is an outer wall window glass. By the way, in an air conditioning system in which the interior air conditioner b and the perimeter air conditioner d are installed together, the interior air conditioner is not affected by the heat load in the perimeter zone c.
While zone a can be air-conditioned, interior zone a and perimeter zone c are each equipped with dedicated air conditioners b and d.
This not only increases the initial cost and running cost, but also requires the installation of cold/hot water and drain piping (p), which is difficult to install. At the same time, there were various problems such as the space required and the risk of water leakage. In addition, a blind t is installed in the perimeter air conditioner d.
It also has the disadvantage that it obstructs the view because it is attached to the building. On the other hand, with interior air conditioner b, it is difficult to grasp the number of people to be accommodated at the time of design or construction, and therefore the amount of outside air introduced is set based on the estimated number of people to be accommodated.Therefore, as shown in Table 1, The outside air load accounts for a very large proportion of the total load, consuming unnecessary heat energy.

[Table] (However, the values in this table assume that the upper and lower floors are also in air conditioning mode, the capacity is 0.2 people/m ² , the window opening ratio (windows/outer walls + windows) is 28%, and the amount of outside air is 20 m ³ / (People/Hr, draft...0.5 times/Hr in summer, 1.0 times/Hr in winter.) Therefore, this invention is an interior air conditioning system that can solve the above-mentioned problems at once. It provides: Embodiments of the present invention will be described below with reference to FIGS. 2 to 4. The figure shows arbitrary floors of the office building BD, where 1 is a living room and 2 is an equipment room that is installed in parallel with the living room 1 and has an interior air conditioner 3 installed therein. The interior air conditioner 3 is an air handling unit, and includes a casing 7 having a partition wall 4 in the center, with a return air chamber 5 on the upper side and an air supply chamber 6 on the lower side, An air filter 9, a cold/hot water coil 10, and a supply air blower 11 are installed in the room 6 in order from the outside air intake 8 side, and an air filter 12 and a return air blower 13 are installed in the return air chamber 5.

and an outside air enthalpy detector 22 installed on the air supply path 21 side. The supply air blower 11 includes respective branch ducts 2.
3 is connected to an air supply duct 26 which is connected to a plurality of blowout slots 25 installed in the ceiling wall 24 of the living room 1. The return air room 5 includes the ceiling wall 24 of the living room 1.
A return air duct 28 is connected to an exhaust slot 27 installed at the bottom. The supply air damper 15, exhaust damper 16, and return air damper 17 have a single-axis interlocking structure, and when the CO ₂ detector 19 operates and outputs a detection signal, the operation motor 29 is driven by the CO 2 detector 19. The opening degree of each of the dampers 15 to 17 is set by the same shaft. The respective dampers 15 to 17 are in such a relationship that when the return air damper 17 operates in the direction of opening, the supply air damper 15 and the exhaust damper 16 operate in the direction of closing, conversely. The CO ₂ detector 19 outputs a detection signal in stages according to the CO ₂ concentration of the return air, and when the CO ₂ concentration exceeds 1000 ppm specified by building environmental standards, the return air damper 17 operates in the closing direction. And,
The air supply damper 15 and the exhaust damper 16 operate in the direction in which they are opened. The operation motor 29 may be a pulse motor or a step motor. The temperature control valve 31 of the cold/hot water coil 10 is operated by a detection signal output from an indoor temperature setting device 30 installed in the living room 1, thereby adjusting the appropriate temperature of the supply air passing through the cold/hot water coil 10. will be done. Further, during precooling/prewarming operation, if there is a load on the outside air according to the detection signal output from the return air enthalpy detector 20 and the detection signal output from the outside air enthalpy detector 22, the supply air damper 15,
The exhaust damper 16 and the return air damper 17 are connected to the supply air damper 15 and the exhaust damper 16 via an operation motor 29.
is closed in the range of the amount of outside air introduced in which the CO ₂ concentration of the supplied air is below the set value, and the return air damper 17 is operated to be released. During the intermediate period, the supply air damper 15, exhaust damper 16, and return air damper 17 are activated by the detection signal output from the return air enthalpy detector 20 and the detection signal output from the outside air enthalpy detector 22, and the heating and cooling power is increased. is controlled so that it is minimized. Detection signal output from CO ₂ detector 19 during normal operation, detection signal output from return air enthalpy detector 20 and outside air enthalpy detector 22, output from return air enthalpy detector 20 during precooling/prewarming operation. The detection signal outputted from the outside air enthalpy detector 22, the detection signal outputted from the return air enthalpy detector 20 in the intermediate period, and the detection signal outputted from the outside air enthalpy detector 22 are all determined by the power control. The operating motor 29 is controlled by signals inputted to a controller 32 installed in the panel 18 and containing a microcomputer, and outputted from the controller 32. Further, the detection signal output from the indoor temperature setting device 30 is input to the controller 32, and the temperature control valve 31 is controlled by the signal output from the controller 32. According to the interior air conditioner 3 having such a configuration, the outside air taken in from the outside air intake port 8 by the operation of the air supply blower 11 passes through the total heat exchanger 14 and the air supply damper 15 as shown by the arrow. The air is introduced into the air supply chamber 6 through the air filter 9, the hot and cold water coil 10, the air supply blower 11, and the air supply duct 2.
6. The air is introduced into the living room 1 from each blowout slot 25 through the branch duct 23. The air supplied into the living room 1 is supplied to the interior zone 33 in the same way as in the known method.
After achieving air conditioning, the exhaust slot 27, return air duct 28, air filter 12, return air blower 1
3, the return air passes through the return air damper 1 in the return air chamber 5.
7 into the air supply chamber 6 and joins with outside air, and the other flows through the exhaust damper 16 and total heat exchanger 14 and is discharged from the exhaust port 34 into the atmosphere. The ratio of the return air that joins with the outside air and the return air that becomes the exhaust air is determined by the opening degree of the exhaust damper 16 and the return air damper 17, and this is due to CO ₂
Depending on the CO ₂ concentration of the return air detected by the detector 19. Further, the amount of outside air introduced from the supply air damper 15 is approximately the same as the amount of exhaust air led out from the exhaust damper 16. A part of the outside air taken in from the outside air intake port 8 is heat exchanged with the exhaust gas by the total heat exchanger 14, purified by the air filter 9, and heat exchanged by the cold/hot water coil 10. And during pre-cooling/pre-warming operation, return air enthalpy detector 20
When there is a load on the outside air according to the detection signal output from the outside air enthalpy detector 22 and the detection signal output from the outside air enthalpy detector 22, the return air damper 17 is fully opened, and the supply air damper 15 and exhaust damper 16 are closed. All return air is introduced into the air supply room 6 and circulated between it and the living room 1. During the intermediate period, the supply air damper 15, exhaust damper 16, and return air damper 17 are operated by the detection signal output from the return air enthalpy detector 20 and the detection signal output from the outside air enthalpy detector 22, and the supply air damper 15, exhaust damper 16, and return air damper 17 are operated. Outside air cooling or heating is performed by introducing outside air from the damper 15. In addition,
In the figure, 35 to 37 are differential pressure sensors, and 38 is a steam valve. On the other hand, a sunlight reflecting barrier 40 is installed at a position separated from the outer wall window glass 39 of the living room 1 by a predetermined distance l. This sunlight reflecting barrier 40 is installed vertically so that it can be displaced in the vertical direction, and when it is displaced upward (FIG. 3), its upper end contacts the ceiling wall 24 and the upper end side is in a closed state, and its lower end is in contact with the window sill. 41 at a predetermined distance l ₁ from the top surface of 41, the lower end side is in an open state. In addition, when the upper end is displaced downward (FIG. 4), the upper end is a predetermined distance l ₂ from the ceiling wall 24.
By locating the window sills 41 apart, the upper end side is in an open state, and the lower end is in contact with the upper surface of the window sill 41, so that the lower end side is in a closed state. When not in use, it is folded from the center and stored in a folded state on the ceiling wall 24 as shown in FIG. This sunlight reflection barrier 40 is generally composed of reflective glass (half mirror glass).
The materials are not limited to these, but can be selected as appropriate, such as textile materials and resin materials that have sunlight reflecting functions and drainage path forming functions.Also, the installation method can be rolled up instead of folded as shown in the example, or fixed in a vertical installation state. You can also do this. Furthermore, an exhaust slot 27 for the interior air conditioner 3 is arranged in the ceiling wall 24 located between the exterior wall window glass 39 and the vertically installed sunlight reflecting barrier 40 as shown in FIGS. 3 and 4. . The sunlight reflecting barrier 40 is set to be displaced upwardly as shown in FIG. 3 when the interior zone 7 is in the cooling season, and downwardly as shown in FIG. 4 when the interior zone 7 is in the heating season or at night. do. Therefore, during the cooling period, the harmonized cool air in the living room 1 is exposed to the sunlight reflecting barrier 40 as shown by the arrow.
From the inlet 42 formed between the window sill 41 and the window sill 41, it flows into the discharge passage 43 formed by the outer wall window glass 39 and the sunlight reflecting barrier 40, flows through this part, and flows into the discharge slot 27. Return air duct 28
sent to. Also, during the heating season or at night,
The harmonized warm air in the living room 1 flows through an inlet 44 formed between the sunlight reflecting barrier 40 and the ceiling wall 24 as shown by the arrow.
From the section, the return air is sent to the return air duct 28 via the exhaust passage 43 and the exhaust slot 27. As a result, the sunlight (solar radiation) that enters the outer wall window glass 39 is reflected by the sunlight reflecting barrier 40, and the heat flowing through the outer wall window glass 39 and the heat flowing from inside the living room 1 to the outside flows through the exhaust passage 43. The flowing return air suppresses its flow through, thereby greatly reducing the solar radiation and the flow-through heat which are the heat load on the perimmeter zone, and the influence on the interior zone 33 is reduced. In the structure shown in FIG. 5, the sunlight reflecting barrier 40 of the above embodiment is bent from the center so that it can be installed at an angle as shown in the figure, and a light reflecting mirror 45 is installed on the top wall of the window sill 41. , in addition to these,
By installing a large number of reflecting prisms 46 on the entire ceiling wall 24, the sunlight coming in from the outer wall window glass 39 is directed into the living room 1 in the order of light reflecting mirror 45 → sunlight reflecting barrier 40 → each reflecting prism 46 as shown by the arrow. The interior of living room 1 is illuminated with natural light. In addition, in the case shown in FIGS. 6 and 7, the sunlight reflecting barrier 40' is constituted by a blind 47 placed on the side of the outer wall window glass 39 and a blocking wall 48 placed on the side of the interior zone 33. However, the same functions and effects as those of the embodiments shown in FIGS. 2 to 4 can be obtained. In this case, the blind 47 reflects solar radiation, and the blocking wall 48 forms a discharge path 43. Therefore, here, the blocking wall 48 is the sunlight reflecting barrier 4 of the above embodiment.
It is placed vertically in the same manner as 0. The blocking wall 48 is generally made of ordinary glass, but it is not limited to this, and can be made of a fiber material, resin material, etc. that has a function of forming a discharge path, and its installation method also includes folding and storage. It is also possible to roll it up and store it without doing so. A known blind 47 is used. In summary, the interior air conditioning system according to the present invention is installed vertically at a position separated from an external wall window glass in a room by a predetermined distance so as to be able to move vertically, and when the system is moved upward, the upper end side is closed. A movable sunlight reflecting barrier whose lower end side is in an open state, and whose upper end side is in an open state and whose lower end side is in a closed state when displaced downward, and is located between the outer wall window glass and the sunlight reflecting barrier. By arranging an exhaust slot connected to the return air path of the air conditioner on the ceiling wall to create a discharge path for conditioned air between the exterior wall window glass and the sunlight reflective barrier, the perimeter between the exterior wall window glass and the sunlight reflective barrier can be improved. A forced air flow is sent to the zone space, and on the other hand, the return air flowing through the return air path is divided into an exhaust path and an air supply path proportionally depending on the CO ₂ concentration, and an exhaust air flow is provided in the air supply path. Since the structure is such that a considerable amount of outside air is introduced, as described in the example, the supply air introduced into the living room simultaneously performs air conditioning in the interior zone and heat load treatment in the perimeter zone. Therefore, there is no need for a dedicated perimeter air conditioner to handle the heat load in the perimeter zone. From this, various problems that arise when installing a perimeter air conditioner can be solved, and at the same time, the initial cost can be significantly reduced. Further, when the sunlight reflection barrier is constructed of reflective glass, particularly half mirror glass, the above-mentioned effect can be achieved without blocking the field of view. The introduction of outside air is done according to the CO ₂ concentration of the return air, and during pre-cooling and pre-warming operations, return air is circulated without introducing outside air, and during the intermediate period, outside air is introduced for outside air cooling or outside air heating. Furthermore, since the outside air introduced is heat exchanged with the exhaust air, there is less loss of thermal energy and it can be used effectively, eliminating the need for the perimeter air conditioner and reducing the・Costs can be significantly reduced. In addition, according to this invention, since indoor air is exhausted from the outside wall window glass side, in the event of a fire, smoke will flow in the opposite direction to the evacuation direction. It has many practical benefits, such as eliminating the risk of running out or inhaling toxic gases. Note that the interior air conditioning system of the present invention is not limited to the illustrated structure, and various design changes may be made to, for example, the structure of the air conditioner or the structure of the sunlight reflection barrier, without departing from the technical idea set forth in the claims. It is possible.
