Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention integrally connects an air conditioner with all outside air and an air conditioner for indoor installation to extremely simplify heat treatment and indoor air treatment with a required amount of outside air. The present invention relates to an energy-saving type air conditioner that can be used both in the open air and in the open air.

[Prior Art] Conventionally, when a large number of rooms such as buildings, department stores, and workplaces are cooled and heated, it is necessary to supply fresh outside air at the same time as the air conditioning.

As a means for introducing such outside air, recently, a so-called total outside air type air conditioner in which a total heat exchanger is installed inside the machine has been developed, but most of these air conditioners mainly focus on heat exchange by outside air. Therefore, when performing indoor air conditioning, another air conditioner must be used as an indoor air processing air conditioner in addition to the above-mentioned outdoor air conditioner, and therefore there is an unavoidable fear of becoming expensive.

[Problems to be solved by the invention] In particular, the use of a plurality of air conditioners for the treatment of the outside and inside air is naturally restricted even in the place of installation. It had a serious drawback in terms of economy such as large power consumption.

The present invention is mainly intended to solve the above-mentioned problems, and the overall shape is formed to be extremely compact, and it is possible to reliably expect the above-mentioned various requirements. Type air conditioners.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the all-outdoor-air-combined type air conditioner according to the present invention has U-shaped ventilation passages A1, A2 and B1, B2 formed in the body. An air conditioner for indoor air treatment is integrally provided adjacent to an all-outdoor-air-conditioning air conditioner in which various mechanisms such as a cooling / heating coil, a blower, and a total heat exchanger are provided in the air passage. Its feature is.

[Embodiment and Its Action] Hereinafter, one embodiment of the present invention will be described with reference to the drawings, and the structure of the outside air processing side air conditioner is ... The outside air intake a, the air supply port b, and the return air are provided on the upper part of the machine body. Air inlets and outlets of an air outlet c and an air outlet d are provided in each opening, and a U-shaped air passage A1 is formed in the body to connect the outside air inlet a and the air inlet b, and the air supply is provided in the passage. The blower 1 and various mechanisms such as the cooling / hot water coil 2 and the humidifier 3 are arranged at the respective places, and by the switching operation of the blower passage adjustment dampers (a) and (a), the outside air flowing through the blower passage A1 is removed. A circuit leading to the ventilation passage A2 through the total heat exchanger 4 which is partially installed in the substantially center of the airframe, and a U-shaped ventilation passage communicating the return air outlet c and the exhaust outlet d on the side adjacent to the ventilation passage A1. B1 is formed and the air passage is formed.
The exhaust blower 5 is returned to the inside of B1, and all the exhaust dampers (c) and exhaust adjustment dampers (d) are arranged in the blower passage A2 so that the blower passages can be switched and adjusted. It is configured so that all of the air flowing through the inside of B1 is exhausted, or a part of the exhaust air is recirculated into the air supply passage A1 on the indoor air supply side.

In addition, one of the indoor air processing side air conditioners is provided with a return air port "e" and an air supply port "f" for the indoor air at the upper part of the airframe, and a U-shape that connects the return air supply ports "e" and "f" to the inside. A blower chamber in which the blower 6 and the electric motor 7 are arranged, and the other side is provided with various mechanisms such as a heat exchange coil 8, a drain pan 9, a humidifier 10, a filter 11 and the like. A heat exchange chamber is formed at a location.

Such an indoor air processing air conditioner is adjacent to the outside air processing air conditioner and integrally connected.

In the figure, 12 and 13 are air filters.

In addition, the above-mentioned air intake and exhaust ports such as the outside air intake a, the air supply ports b and f, and the return air ports c and e are opened in the upper part of the airframe on both sides, and the sound deadening mechanism is appropriately arranged in the hood. A more effective silencing effect can be expected by connecting the chambers 14 integrally.

Next, the operation body will be described. First, the blower passage adjusting dampers (a) and (a) are opened. The entire amount of outside air taken in from the outside air intake a is blown by the air blower 1. Cold, hot water coil flowing through passage A1
2. Heat exchange / humidification is performed at an appropriate temperature in the humidifier 3, and the air is supplied to the ventilation units installed at various locations inside the room through the air supply port b and ducts (not shown) to cool and heat the room. To do.

Alternatively, it is also possible to directly cool the outside air to cool it.

In the case of taking in only the required amount of outside air other than the above-mentioned all outside air cooling, open the damper (a) and adjust the opening and closing of (a) so that part of the outside air flowing to the blower passage A1 side will undergo total heat exchange. It flows through the device 4 in the direction of the air passage A2 and is discharged from the exhaust port b.

Open all exhaust dampers (c) when sending cold air,
The exhaust adjustment damper (D) is closed, and the blower for return and exhaust 5
The total amount of polluted air in the room that is returned to the inside of the machine from the return air port c is discharged through the ventilation passages B1 and A2 to the outside through the exhaust port d.

Further, when a heat quantity is required during the exhaust, the total quantity of exhaust air or a part of the exhaust air flows into the total heat exchanger 4 by opening / closing adjustment of the exhaust gas and the exhaust adjustment dampers (c) and (d).

By operating these exhausts, exhaust adjustment dampers (c) and (d), a part or all of the air that is returned to the inside of the machine from the return air port c does not flow to the total heat exchanger 4 and the air passage B
From 1, the air flows into the air passage A1 and mixes with the outside air to perform heat exchange again.

On the other hand, the air inside the room is blown from the return air port e to the air passage C in the cabin.
It is possible to supply cold / warm air having appropriate temperature and humidity to the room by the mechanism such as the heat exchange coil 8 and the humidifier 10.

.. etc., the present invention is expected to obtain optimum heat exchange in all outside air or a part thereof depending on the indoor environment,
Arbitrary cold and warm air can be easily sent indoors.

[Effects of the Invention] As described above, the present invention is characterized in that an air conditioner having completely different functions, such as an air conditioner for all outside air and an indoor air conditioner, is integrally formed integrally. As described in the section above, various air conditioning controls such as the introduction of all the outside air, the required amount of outside air during the air conditioning of the room, the use of the room warm and cold air, etc. are simply performed by adjusting the damper operation according to the indoor air conditions. Can be done easily and surely.

In particular, the present invention does not require a plurality of air conditioners to be installed as in the conventional machine because the air conditioners of two different machines are integrally formed into one body structure, and therefore the work such as indoor piping and wiring is easy and reliable. Yes, it consumes less power and is very economical.

In addition, as described in claim claim 1, each air intake and exhaust port such as the outside air intake a, the air supply port b, f, the return air port c, e, etc. is opened in the upper part of each aircraft, and a muffling mechanism is installed in the device. It is possible to obtain ultra-low noise air conditioning at the same time by integrally connecting the appropriate silencing chambers 13 in series.
