Abstract

PROBLEM TO BE SOLVED: To prevent a window from being condensed owing to a temperature difference between the inside of a room and fresh air. SOLUTION: A small-sized compressor or an air fan 17 is disposed on an air conditioner or a dehumidifying apparatus 1. Dried air from a suction nozzle 16 heated with a heating coil 5a is sucked, and is injected to an upper portion or a peripheral portion of the window with the aid of an injection nozzle apparatus 19c installed facing a window surface of the window through an air pressure feeding pipe 18 disposed in an air conditioning duct or a ceiling 21, whereby a forced convection air layer is formed on the window surface to prevent moisture on the window glass surface from stagnating and being condensed. Simultaneously, a cold draft phenomenon is also prevented, which is occurred owing to a temperature difference between the inside and outside of the room.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which a small compressor or a blower is installed, and air is blown into a window on the indoor side of a building through an air pressure pipe to prevent dew condensation. The present invention relates to a system for preventing a cold draft phenomenon caused by a temperature difference between a room and outside air.

[0002]

2. Description of the Related Art Conventionally, air connected from an air conditioner: 1 to a room: 11 through an air supply fan: 2 and an air supply duct: 8, and an air outlet installed at a window side are used. Then, it was sprayed on the surface of the window glass: 19a to prevent condensation. However, if the distance between the outlet 10 and the window glass 19a is too large, the blow-out air does not reach the surface of the window glass 19a, and the prevention of dew condensation is incomplete. In particular, the dew condensation on the frame of the window sash 19: 19a Was not so effective. Therefore, the use of double sashes or double glazings has improved the effect of preventing dew condensation, but in cold regions the effect is not sufficient, and the cost of construction is high, so there are many cases in which the device is not installed.

[0003]

Therefore, a system has been devised which can be easily installed regardless of whether it is a new building or an existing building, and has a low construction cost and a large effect of preventing dew condensation.

[0004]

[Means for Solving the Problems] (A) Suction nozzle: 1
6 small compressor or blower: 17 air pressure pipe: 18 and its control device as air conditioner or dehumidifier:
It is attached to 1. (B) Pneumatic feed pipe: 18 is installed inside the air supply duct 8 and does not need to be fixed, does not require any special installation space, and is not limited to a new construction, but is an air supply duct even for existing equipment. : 8 and in the ceiling: 21 can be easily installed if there is space. (C) Window sash frame: The surface of the window glass 19a, the double sash, and the hollow layer of the paired glass by the air jetting from the jet nozzle provided in the frame 19b or the jet nozzle device 19c installed independently. The formation of a forced convection air layer on the floor prevents condensation and reduces the deterioration of the indoor thermal environment due to the cold draft on the window surface

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION 1: An ordinary air conditioner or
In the dehumidifying device, devices such as a filter: 3 and an air supply fan: 2 are housed therein, and a cooling coil: 4a for a cooling device: 4, a heating coil for a heating device: 5: 5a, a humidifying device: 6 and a humidifying mist removing eliminator: 7 are also stored. The air conditioner: 1 is provided indoors through an air supply duct: 8 and an air supply chamber: 9;
While being communicatively connected to 11, Room: 11 return air fan to: return air duct with 12: 13 is communicatively connected, the return air duct: 13 exhaust duct via an exhaust damper D _1: 14, a return air damper: D ₂ , and a fresh air intake duct: 15, which is in communication with the outside air intake duct: 15, respectively, and the outside air intake duct: 15 has an outside air intake damper: D.
₃ are interposed. From the suction nozzle: 16, the dry air heated by the heating coil: 5a and before passing through the humidifying device is taken in, and a small compressor or blower: 17
The suction and compression of the circulating air causes the air supply duct: 8
Inside or ceiling: Pneumatic feed pipe installed at 21:
18, a window sash installed on the window surface of the room: 11, a frame: 19 b of the 19, and a single jet nozzle device: 19 c directly connected to the pneumatic feed pipe: 18, and pressure-fed to the upper portion of the window surface. Or, by the ejection nozzle provided in the peripheral part,
The forced convection air layer is formed by spraying on the surface on the 11th side of the window glass: 19a, the double sash, and the hollow layer of the paired glass.

[0006]

The forced convection air layer formed on the surface on the 11th side of the window glass: 19a, the double sash and the hollow layer of the paired glass prevents stagnation of moisture on the surface of the window glass and prevents dew condensation. Also, by drying and sending the dried air warmed by the heating coil 5a to the frame 19b of the window sash 19 and passing it through, the frame 19b can be heated to prevent dew condensation at that portion. Also, due to the temperature difference between the room: 11 and the outside air: 20, in the winter, the air cooled on the surface of the window glass: 19a flows into the room, and in the summer, the heated air flows into the room. The cold draft phenomenon that causes discomfort caused by the accident can be prevented, and the living environment of the room 11 can be improved.
