Description

Energy-saving type air conditioning system integrated fan coil with curtain wall having vents}

The present invention relates to a building indoor air conditioning system combining a curtain wall and a fan coil unit of a ventilated structure, and more specifically, it is heated and raised by a black body plate which flows into the lower part of the curtain wall and collects solar radiation heat. By supplying the outdoor air into the fan coil unit through the outdoor air inlet provided in the upper part of the curtain wall and supplying it indoors, it is used as auxiliary heating heat source in winter to reduce the heating cost and ventilate the room, and in summer, the damper in the upper part of the curtain wall Ventilation curtain wall and fan to reduce air conditioning costs by blocking outdoor air intake, and outdoor air flowing into the lower part of the curtain wall to prevent natural air from being heated through the upper part of the curtain wall. An integrated energy saving air conditioning system using a coil unit.

Recently constructed high-rise buildings, after the steel frame structure consisting of columns, beams and slabs is completed, the outer wall wall is fixed to the outside of the fixing frame attached to the outside of the steel frame structure, the inside of the fixing frame to block the wall by fixing the wall It is common for construction to be completed.

In addition, unlike the walls constructed with ready-mixed concrete, cement brick, and insulation, the outer wall of the high-rise building constructed as described above is inferior in thermal insulation, so that it is more effective for efficient utilization of energy required for operation of air conditioning facilities such as heating and cooling high-rise buildings. Although it is urgently needed to secure the insulation means, the insulation construction of the exterior walls in high-rise buildings was not a significant problem.

In particular, in modern high-rise buildings, aesthetics, etc. are taken into consideration, so that a very wide window is provided compared to a general residential building, so that the thermal insulation is further inferior. Although it is suppressed to some extent, buildings are becoming high-rise and special windows are applied to reduce heat loss, so most windows are fixed to walls and sealed to pursue high airtightness, making it difficult to naturally ventilate the room. Became the main. In addition, the office of the winter office building has a problem that consumes a lot of heating energy by increasing the heating load due to solar radiation by applying a blind to block solar direct sunlight.

In order to improve the weakness of high-rise buildings with low thermal insulation as described above, a fan coil unit is installed in the lower part of the indoor window when designing an air conditioning system, and in particular, a method of reducing heat loss from a window with a large amount of thermal loss may be applied.

However, the fan coil unit, which has been conventionally applied, is a method of circulating indoor air, and thus, it is difficult to introduce fresh outside air from the outside, and thus it is not possible to prevent deterioration of indoor air, and even to filter indoor air. There is a problem that cannot use a high performance purification filter.

In addition, the conventional fan coil unit is difficult to cool the outside air, the heat recovery, and there is little energy waste due to this, air flow window system (airflow window system) has been developed and applied in Japan, Europe, etc. to solve this problem, The airflow window system is difficult to be introduced into high-rise buildings due to excessive initial cost and weight of windows.

In addition, Korean Patent Publication No. 95-18987 discloses a structure that obtains a thermal insulation effect by forming a space between an outer wall plate attached to a fixing frame, that is, a curtain wall and an interior inner barrier wall coated with a heat radiation reflecting film. This structure has a problem that the air existing in the space between the curtain wall and the barrier wall of the opaque structure is stagnant, and this air is heated by solar heat in summer to cause an increase in the indoor temperature of the building.

In order to improve the shortcomings of the structure, Korean Patent Publication No. 97-75142 discloses that the air inlet pipe is buried underground from the ground to the ground contact portion of the space between the opaque curtain wall and the interior inner barrier wall coated with the heat radiation reflecting film. Is connected to the lower portion of the space between the curtain wall and the interior interior barrier wall, the structure is provided with an air outlet inside the roof of the building rooftop, but the inflow of air through the pipe may not be smooth, Although air is emitted through the roof railings, high-rise buildings cannot prevent the room temperature from going upstream.

In addition, Korean Patent Laid-Open Publication No. 99-24101 discloses a ferry cover system having a window and a low speed duct provided with a ventilation window at the bottom thereof, but using an internal air conditioning system, in particular, using the heat radiation radiation of winter solar heat. It does not have a structure.

In addition, in Korean Patent Publication No. 94-8241, a blind is installed between glass windows in a manner of using a pneumatic heat collection window to fully utilize solar radiation heat, but this does not introduce outdoor air, but only circulates indoor air, thereby indoors. Only the effect of blocking heat loss is achieved.

Therefore, the present invention has been devised to solve various problems of the air conditioning system applied to the conventional buildings, and it can reduce the heating energy consumption by using solar energy to the maximum and maintain the indoor environment comfortably by using outdoor air. It is an object of the present invention to provide an energy saving air conditioning system.
