Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes the entire body vertically long and slender, and introduces fresh outside air into the room as well as making the most effective use of the amount of heat in the exhaust air that has been conventionally exhausted randomly. The present invention relates to an economical floor-standing type ventilation unit for air conditioning, which intends to greatly reduce energy consumption.

[0002]

2. Description of the Related Art Usually, there are four seasons when air conditioning is not required, that is, from May to July when fresh outside air is required. In addition, most of the air conditioners that have been developed so far are for indoor cooling and heating air conditioners, so direct cooling by outside air is not possible, and these air conditioners have various mechanical devices in a narrow space. Due to the clutter, the overall height of the aircraft is bulky, the effective installation surface is restricted, and the noise generated inside the aircraft flows out into the room along with air supply. As an air conditioner for a vehicle, there were various problems.

[0003]

In order to solve such a drawback, the inventor first formed the whole shape into a small size and compactly, and not only in a narrow place in a room but also in any space such as a veranda or a roof. We have also developed a ventilation unit (Japanese Patent Application No. 5-98271) that can be installed easily and at the same time can be directly cooled by outside air. This invention further improves a part of the ventilation unit according to the above development, Its main purpose is to make more efficient use of the amount of heat in the return air and to significantly reduce the consumption of heat energy used.

[0004]

As means for achieving the above-mentioned object, the present invention has an air supply port 2 and a return air port 3 on the back of a machine body 1 formed in a vertically long shape, and an exhaust port 4 and an outside air on the front. Each intake and exhaust ports such as the intake port 5 are provided with openings, and inside the machine body, an air supply chamber A, a blower chamber B, an outside air introduction chamber C, an exhaust chamber D, and a return air chamber E are vertically formed side by side. . Further, the respective return, intake, and exhaust ports are communicated with each other through the exhaust air blow passage 6a and the air blow passage 6b, and the cooling / heating coil 7 and the drain pan 8 are provided in the air supply chamber A and the blower chamber B is provided. For air supply 9
A return air blower 11 is provided in the return air chamber E, and a mechanism device required for each of the total heat or the sensible heat exchanger 12 is arranged between the outside air introduction chamber C and the exhaust chamber D. Both ventilation passages 6a,
By-pass passage 6c is provided between b to connect by-pass passage 6
A blower passage switching damper F is installed in c so that the air flowing through the machine can be returned by the damper operation, and the switching operation can be performed in any direction such as exhaust or cooling of all outside air. Further, according to the present invention, in the above configuration, the refrigerator 10 (compressor) is further installed in the return air chamber E, and the condenser coil 13 is installed in the exhaust chamber D to reuse the reheat air in the return air from the room. It is characterized by making it more effective.

The present invention further includes the above-mentioned air passages 6a and 6b.
A vertical rhombus-shaped total heat or sensible heat exchanger 12 is arranged vertically, or a plurality of total heat or sensible heat exchangers 12 are arranged vertically in parallel, or in the front part of the machine body 1. The front panel 17 is attached so as to be openable and closable, and the above-mentioned machine body 1
An air supply pipe 18 having an appropriate sound deadening mechanism installed therein is connected to an air supply port 2 which is provided at the back of the vehicle so that noiseless air can be sent to the room. .

[0006]

The ventilation unit having the above-mentioned structure is installed not only in the corners of the room, but also in the gaps, as well as in the corridor, the balcony, etc., outside the room, and the return air port 3 and the air supply port 2 are directly or The duct is connected to open the inside of the room, and the exhaust port 4 and the outside air intake 5 are connected to the outside either directly or by duct connection. In this state, when the blower passage switching damper F is fully closed by the operation of the return and exhaust blowers 9 and 11, the contaminated air on the indoor side is returned from the return air port 3 (arrow A) through the blower passage 6a to the exhaust port 4. On the other hand, the fresh air that is discharged to the outside of the room flows from the outside air intake 5 to the outside air introduction chamber C (arrow a) through the air supply passage 6b and the air supply chamber A into the room through the air supply port 2 as appropriate cooling and warming air. Send appropriate cooling and heating to the delivery room.
Since the return air from the room passes through the total heat or the sensible heat exchanger 12 at the time of exhausting the air during the air flow, part of the amount of heat is recovered. In particular, the present invention cools the refrigerator 10 (compressor) during circulation of the return air by cooling the indoor side return air (arrow A) contained in the return air during cooling, The air is exhausted by the operation of 11 and passes through the total heat or sensible heat exchanger 12, and the exhaust chamber D
The condenser coil 13 installed inside is cooled and discharged to the outside. On the other hand, fresh air from the outside passes through the total heat or the sensible heat exchanger 12 by the operation of the air supply blower 9 and is cooled and heated to an appropriate temperature by the cooling / heating coil 7 installed in the air supply chamber A. It is possible to blow a predetermined amount of cool air into the room. The cooling coil 7 becomes a heating coil by switching the four-way valve, and a better heating effect can be obtained. Further, when the room is further dried during heating and cooling and proper humidification is required, it is possible to supply appropriate humidified air by operating the humidifier 14 at the same time. Next, the blower passage switching damper F is opened and the damper F1 in the exhaust chamber D is closed, so that the return air from the room is bypassed by the bypass passage 6c.
Therefore, it is possible to flow a part or the whole amount of the return air flowing in the air passage 6b to the air supply chamber A direction and to perform the re-supply with the outside air without discarding the whole amount of the return air. Further, when the outside air cooling is required without the need for cooling and heating depending on the indoor environment, time, etc., the outside air passes through the sensible heat exchanger 12 by fully opening the damper F in the bypass passage 6c. The air flows directly into the blower chamber B (arrow C) without any operation, and fresh outside air is directly fed into the room from the air supply port 2 to obtain cooling by the outside air. In the case of the above, water flow to the cooling / heating coil 7 is stopped during that time. However, if more cooling temperature is required, the coil 7 is supplemented with a refrigerant, and in the case of supercooling, It can be easily solved by adjusting the opening and closing of the damper F. As described above, in the present invention, the ventilation passages 6a, 6b
By installing the total heat or sensible heat exchanger 12, the refrigerator 10, and the condenser coil 13 inside, the amount of heat retained in the air can be fully reused, and the indoor space can be economically used with a small amount of heat. It can be air-conditioned.
