Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air clean system in a small-to-medium-sized facility system, and particularly to a clean air conditioner unit suitable for an operating room of a hospital and a newborn room.

[0002]

[Prior Art]

 Conventionally, this type of air conditioner (hereinafter, referred to as an air conditioner) has an air conditioner and an air purifier connected in series through a duct as shown in FIG. 4, or an air conditioner as shown in FIG. In some cases, an ultra-high performance filter (hereinafter referred to as HEPA filter) was attached to the suction part and integrated.

In these conventional examples, when an air conditioner and an air purifier are connected in series, two air blowers having different characteristics are connected, which makes it difficult to adjust the air volume during operation. Since the units are arranged side by side via ducts, they often occupy a large space for installation, which often hinders the air-clean design and its construction.

On the other hand, when the HEPA filter is provided in the suction part of the air conditioner, even if the suctioned air becomes clean, it is difficult to remove it with high precision due to dust generation inside the device main body, and it is difficult to clean the blown air. The condition was unstable.

Further, as a problem in taking in the outside air, if the contaminated outside air is directly introduced into the air conditioner, a mixture of the contaminated outside air and the purified intake air is blown out into the room. However, since it is not possible to clean the air in the room, there was the inconvenience of having to install a separate device for cleaning the outside air.

[0006]

[Problems to be Solved by the Invention] As described above, the problems in the conventional example are, in other words, consideration of consistency of connected devices, adjustment, and multi-industry / multi-step construction of component equipment, which results in a burden on construction. In addition, due to the operational restrictions of the air conditioner, the combination of HEPA filters has been shunned because the combination of HEPA filters causes a decrease in air flow due to an increase in static pressure due to clogging. Especially.

[0007] In addition, due to the simplicity of the equipment system, the adoption of an individual air cleaning system instead of the central duct system is becoming widespread in small and medium sized clean rooms (classes 10 ⁴ to 10 ⁵ ). Yes, compact integration of individual devices is expected here.

The present invention has been made in view of the above circumstances, and solves the above problems and integrates an air cleaning function and an air conditioner function to make the entire apparatus compact and simplify the installation work. The purpose is to provide a clean air conditioner unit that can be converted into a new type.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides an air conditioner having an air cleaning function, in which a panel is attached to the front of a box-shaped main body lined with a sound absorbing material so as to be separable from the main body. In one of the areas divided across, the HEPA filter is detachably attached to the outlet, and in one of the other areas, the inlet with the pre-filter and variable guide vane is formed. An outside air inlet is provided on the side of the main body on the suction side, and a direct expansion coil and a blower are arranged inside the main body behind the panel, and these are housed and integrated in a casing.

Further, a suction variable louver is attached to the suction port, and the other configuration is a clean air conditioner unit similar to the above.

[0011]

Embodiment 1 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a central longitudinal sectional view showing an embodiment of the clean air conditioner unit of the present invention, and FIG. 2 is a front view of the same. In the figure, (1) is a main body, which is formed in a box shape and prevents noise and dew condensation on the inner surface. A sound absorbing material (11) is lined, and a panel (2) is attached to the front surface of the main body so as to be separable from the main body (1).

Reference numeral (3) is an air outlet, which is formed in one of the divided regions across the longitudinal direction of the panel (2), and the HEPA filter (4) is detachably attached thereto.

An intake port (6) having a pre-filter (12) and a variable guide vane (5) is formed in one of the other divided regions, and an outside air intake port (9) is formed on the side surface of the main body on the intake side. The direct expansion coil (7) and the blower device (8) are arranged inside the main body (1) behind the panel. The outside air intake (9) is equipped with an air flow rate adjusting valve (10).

Since the main body (1) and the panel (2) of the clean air conditioner unit of the present invention can be separated, the panel (2) can be attached even after the ceiling board is stretched.

In operation of this device, by driving the blower device (8), the indoor air from the suction port (6) and the outside air from the outside air intake port (9) are simultaneously sucked into the main body (1), The temperature of the air is adjusted by the direct expansion coil (7) while mixing both air, and then the air is diffused into the passage inside the main body through the air blower (8) and passed through the entire surface of the HEPA filter (4) to obtain a fine particle. Air that has been cleaned by removing dust is blown out into the room from the air outlet (6).

The air blower (8) is supposed to have an air flow rate changing means for dealing with a decrease in air flow rate due to filter clogging, etc., to ensure a predetermined air flow rate and to operate at a constant air flow rate during defrost operation and cooling / heating heat load fluctuations. Is to do.

FIG. 3 is a central longitudinal sectional view similar to FIG. 1 showing another embodiment, in which a suction variable louver (13) is used in the suction port (6) instead of the variable guide vane. The other configurations are the same as those in FIG.

FIG. 4 is an explanatory view of a connection type air clean system in a conventional example, in which an air conditioner (A) and an air purifier (B) are connected in series via a duct (C), and air is , Is sucked in from the outside air introduction section (G) and suction section (D) on the air conditioner (A) side, and passes through the above-mentioned equipment, and passes through the HEPA filter (F) on the air purifier (B) side for cleaning. This is a general example of the individual method in which the air is blown out and blown out from the blowout section (E). Here, each unit (or sub-unit) of suction, air conditioning, ventilation, and purification / blowing is connected side by side via a duct to form a series route. In this case, as mentioned above, it is difficult to adjust the air flow rate during series operation, and there are also many issues to be considered such as equipment consistency and installation space, which poses a heavy construction burden.

FIG. 5 is an explanatory view of an air clean system in which a HEPA filter (F ′) is attached to a suction part (D ′) of an air conditioner (A ′) in another conventional example, and the suction part (D ′) This is an example in which is installed in the center of the front surface of the main body, and the surrounding area is integrated as an outlet (E '). Even in this case, as described above, contamination due to dust inside the equipment body is unavoidable, and there has been a problem that the air conditioner function deteriorates due to separate placement of clean equipment when introducing outside air and clogging of filters. ..
