JPH063308Y2 - Ultra low noise air conditioner - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention, in an air conditioner for heating and cooling installed in a room or the like, reliably eliminates the noise of noise generated during operation of the air conditioner to ensure a comfortable operation at all times. It relates to an ultra-low noise type air conditioner that seeks to provide a quiet environment.

[Prior Art] Conventionally, when any of the air conditioners used for indoor cooling and heating is out of use, noisy vibration sounds are emitted together with cooling and heating air in the room, which causes serious problems for mental health. There was a problem to eliminate noise in the room, which is affected by low noise, especially in hospitals and laboratories.

[Problems to be Solved by the Invention and Means Therefor] In view of the above problems, the present invention provides a filter, a blower, a heat exchange coil, a valve, in a blower passage formed in an inverted N shape.
By disposing required mechanisms such as a controller at each location and providing a plurality of noise reduction mechanisms in the air passages on both the front and rear sides of the heat exchange coil, the noise in the aircraft, which has been a problem to be solved in the past, has been eliminated. With the mechanism, it is possible to easily and completely erase the air conditioner to easily obtain the desired ultra-low noise air conditioning.

[Operation] The air that can be introduced into the ventilation passage from the suction port is filtered by the filter mechanism, passes through the blower chamber and the heat exchange chamber, and heat is exchanged to a predetermined temperature during that time, and cool / warm air of an appropriate temperature is sent from the outlet to the room. To pay.

The noise generated in the machine at the same time as the supply of cold / warm air is gradually reduced by the action of the N-shaped air passage, and the noise is more effective due to the function of the two-stage silencer before and after the heat exchange coil. It is possible to easily supply the cold and warm air with almost no noise and low noise, such as effective noise reduction.

[Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the inside of a machine body 1, a plurality of partition plates 2 and 2 form an inverted N-shaped air passage, and suction is provided at one upper part of the passage. Each of the openings 3 is provided with an outlet 4 at the other end, and a dust removing mechanism such as a pre-filter 5 and a main filter 6 is provided in the upper part of the suction side air passage, and a blower mechanism such as a blower 7 and an electric motor 8 is provided in the lower part. Each of the blower chambers A to be arranged and a heat exchange chamber B in which the heat exchange coil 9 is arranged in an inclined manner are formed in the blower side blower passage, and the front and rear blower passages of the heat exchange coil 9 of the blower chamber A are provided. A front silencing chamber 10 and a rear silencing chamber 11 are formed in each of these, and an appropriate silencing mechanism is installed in each of the front and rear silencing chambers 10, 11.

Reference numeral 12 indicates a drain pan, and other mechanisms such as a valve mechanism, a control device, a humidifier, etc. are installed in the air passage of the machine as necessary.

In some cases, it is possible to install the heat exchange coil 9 in the heat exchange chamber B vertically without tilting it or to arrange the filter mechanism horizontally.

[Advantages of the Invention] In the present invention, an inverted N-shaped air passage is formed in the airframe 1 as described above, and the filters 5, 6, the air blower 7, and the heat exchange coil 9 are installed in the air passage. Since the front and rear muffling chambers 10 and 11 are formed on both front and rear sides of the heat exchange coil 9 and a plurality of muffling mechanisms are integrally provided in each chamber, the muffling mechanism having two stages before and after the air circulation. The sound deadening effect can be expected with certainty, and in particular, the noise damping chamber 11 installed near the outlet of the above-mentioned sound deadening mechanism can be used to more reliably and effectively generate some noise that may be leaked during indoor ventilation. It can be erased.

Further, in the present invention, since the entire ventilation passage is formed by the substantially N-shaped ventilation passage, the ventilation distance is naturally long and noise is naturally eliminated during ventilation. In addition, the arrangement space for various device mechanisms such as valves and control mechanisms is sufficient, and in addition, the entire body can be compactly formed due to the oblique arrangement of the filters and heat exchange coils.

Therefore, the air conditioner according to the present invention can be said to be the most suitable device not only for laboratories and hospitals but also for places such as perimeters and refresh rooms where low noise is particularly required.
