Description

환기냉방용 디퓨저{DIFFUSER FOR VENTILATING AND COOLING A ROOM}Diffuser for Ventilation and Cooling {DIFFUSER FOR VENTILATING AND COOLING A ROOM}

본 고안은 실내에 신선한 외부공기를 환기와 냉방을 겸할 수 있는 환기냉방용 디퓨저에 관한 것이다. The present invention relates to a ventilating cooling diffuser capable of both ventilation and cooling of fresh outside air in the room.

종래 실내 환기에는 베란다나 장비실에 설치된 환기유니트와 덕트로 연관되는 유입구 및 유출구가 구비된 급기디퓨저(diffuser)와 배기디퓨저를 천장의 공간에 설치하여 외기를 실내에 공급하고 실내의 공기를 흡인하여 외부로 배출하게 되어 있다. Conventional indoor ventilation is provided with an air diffuser and an exhaust diffuser equipped with an inlet and an outlet connected to a ventilation unit and a duct installed in a veranda or an equipment room in a ceiling space to supply the outside air to the room, and to suck in the indoor air. To be discharged.

또 냉방시에는 베란다나 장비실에 공조의 실외기를 설치하고 냉매관 및 가스관으로 연관된 에어콘을 실내에 설치하여 환기와 별도로 냉방을 하였다.In the air-conditioning, air conditioners were installed in verandas and equipment rooms, and air-conditioners connected to refrigerant pipes and gas pipes were installed in the room for cooling separately from ventilation.

따라서 실내에는 별도의 에어콘이 설치되기 때문에 유효공간이 잠식되어 좁아지는 문제와, 에어콘의 점검 및 관리가 불편한 문제점이 있었다.Therefore, since a separate air conditioner is installed in the room, there is a problem that the effective space is encroached and narrowed, and a problem of checking and managing the air conditioner is inconvenient.

본 고안자는 상기한 문제점을 시정하기 위하여, 베란다나 장비실에는 환기유니트 및 공조실외기를 설치하고 상기 환기유니트와 덕트로 연관된 급기디퓨저의 내 부에, 상기 실외기와 냉매관 및 가스관으로 연관된 증발기인 열 교환기를 설치하여 외부의 신선한 공기를 디퓨저를 통하여 실내에 공급하기 직전에 급기디퓨저의 내부에 구비된 열 교환기에 의하여 외기를 냉방에 유효한 온도로 냉각하면서 실내에 공급하는 새로운 환기 및 냉방시스템을 개발하여 특허출원하였다.(10-2009-0050386호 2009.06.08출원)In order to correct the above problems, the present inventors install a ventilation unit and an air conditioner outdoor unit in a veranda or an equipment room, and a heat exchanger that is an evaporator associated with the outdoor unit, a refrigerant pipe, and a gas pipe inside the air supply diffuser connected to the ventilation unit and the duct. Developed and patented a new ventilation and cooling system to supply the indoor air while cooling the outside air to the effective temperature for cooling by the heat exchanger provided inside the air supply diffuser just before supplying the fresh air to the room through the diffuser (Application No. 10-2009-0050386 2009.06.08)

종래의 환기용 급기디퓨저는 하우징에 공기의 유입구 및 유출구만 구성되어 있어, 환기와 냉방을 겸할 수 없는 문제점이 있었다. Conventional air supply diffuser has a problem that only the inlet and outlet of the air is configured in the housing, can not combine ventilation and cooling.

또한 본 고안자가 환기와 냉방을 겸하는 시스템을 개발하였기 때문에 이에 적용되는, 환기와 냉방을 겸할 수 있는 다양한 디퓨저의 개발이 요청되는 실정에 있다.  In addition, since the present inventors have developed a system that serves as both ventilation and cooling, there is a demand for the development of various diffusers capable of both ventilation and cooling.

본 고안은 이러한 종래의 문제점을 시정하고 환기와 냉방을 겸할 수 있는 급기디퓨저의 개발이 요청되는 실정을 감안하여, 새로운 환기와 냉방을 겸할 수 있는 급기디퓨저를 고안하였다.The present invention has been made in view of the situation that the development of the air supply diffuser capable of correcting such a conventional problem and also serves as ventilation and cooling, devised an air supply diffuser capable of both new ventilation and cooling.

즉, 베란다나 장비실에 설치되는 환기유니트에 덕트로 관접되는 외기 유입구와 그릴을 가진 유출구가 구비된 급기디퓨저(diffuser)에 있어서, 천장에 설치되는 상기 급기디퓨저의 하우징내부에는, 베란다에 설치된 공조실외기와 냉매관 및 가스관으로 연관된 하나 또는 복수의 증발기인 열 교환기와, 응축수받이를 형성하여, 실내에 공급되는 외기를 냉각하여 환기와 냉방을 겸할 수 있게 구성된 것이다.That is, in the air diffuser provided with an air inlet and a outlet having a grill, which are connected to the duct in a ventilation unit installed in the veranda or the equipment room, the air conditioner outside the air conditioner installed in the veranda is provided in the housing of the air diffuser installed on the ceiling. And a heat exchanger, which is one or a plurality of evaporators associated with a refrigerant pipe and a gas pipe, and a condensate receiver, to cool the outside air supplied to the room, and to perform both ventilation and cooling.

본 고안은 천장에 설치되는 급기디퓨저의 하우징내부에 실외기와 냉매관 및 가스관으로 연관된 열 교환기가 형성되어 있기 때문에 외관적으로는 일반 디퓨저와 유사하고 부피가 작기 때문에 천장의 좁은 공간에 용이하게 설치할 수 있다.The present invention has a heat exchanger associated with an outdoor unit, a refrigerant pipe, and a gas pipe, formed inside the housing of the air supply diffuser installed on the ceiling, so that it can be easily installed in a narrow space of the ceiling because it is similar in appearance to the general diffuser and is small in volume. have.

본 고안에 의하면 환기유니트의 가동에 따라 환기유니트에 구비된 급기팬과 배기팬에 의하여 외기의 신선한 공기가 덕트를 통하여 급기디퓨저로 유입되어 유출구로 유출되기 직전에 하우징내부에 형성된 열 교환기에 의하여 냉방에 유효한 온도(약 18℃)로 냉각된 다음 실내에 공급된다. 따라서 실내에는 냉각된 신선한 공기가 공급되고 실내의 공기는 배기디퓨저로 흡입되어 덕트와 환기유니트를 통하여 외부로 배출되어 실내의 환기와 냉방이 동시에 유지된다.According to the present invention, the fresh air of the outside air is introduced into the air supply diffuser through the duct by the air supply fan and the exhaust fan provided in the air supply unit and the air exchanger is formed inside the housing just before the air outlet flows out. Is cooled to an effective temperature (about 18 ° C.) and then supplied to the room. Therefore, the fresh air is supplied to the room, and the air in the room is sucked into the exhaust diffuser and discharged to the outside through the duct and the ventilation unit to maintain the ventilation and cooling of the room at the same time.

또 냉각기의 표면에 응결된 응축수는 응축수받이에 집수되어 배수관을 통하여 외부로 배출되거나 증발되게 하면 된다.In addition, condensate condensed on the surface of the cooler may be collected in the condensate receiver and discharged or evaporated to the outside through a drain pipe.

또 급기디퓨저의 급기구와 유출구는 디퓨저의 설치위치와 덕트의 유입되는 방향에 따라 그에 상응한 방향으로 형성되며, 따라서 디퓨저의 설치가 용이하다.In addition, the air supply port and the outlet of the air supply diffuser are formed in a corresponding direction according to the installation position of the diffuser and the inflow direction of the duct, it is easy to install the diffuser.

또 디퓨저에는 기계적 가동부분이 없기 때문에 기계적 소음이 없고 고장요소가 없기 때문에 관리가 간편하고 청소가 용이하다. In addition, the diffuser has no mechanical moving parts, so there is no mechanical noise and no troubles, so it is easy to manage and easy to clean.

본 고안은 환기유니트에 덕트로 관접되는 외기 유입구와 유출구가 구비된 디퓨저(diffuser)에 있어서, 천장에 설치되는 상기 급기디퓨저의 하우징내부에 실외기와 냉매관 및 가스관으로 연관된 하나 또는 복수의 증발기인 열 교환기와, 응축수받이를 형성하여 구성하였기 때문에 구조가 간단하여 천장내부의 좁은 공간에 용이하게 설치할 수 있다.The present invention is a diffuser provided with an outdoor air inlet and an outlet that are connected to the ventilation unit by a duct, the heat being one or a plurality of evaporators associated with an outdoor unit, a refrigerant pipe and a gas pipe in a housing of the air supply diffuser installed on the ceiling. Since the exchanger and the condensate receiver are formed, the structure is simple and can be easily installed in a narrow space inside the ceiling.

환기되는 신선한 외기를 급기디퓨저에 의해서 실내에 공급할 때 공기를 냉방에 유효한 온도로 냉각시키어 공급하기 때문에 실내에 에어콘 등의 설치가 생략되어 유효공간이 확장된다.When fresh air is ventilated and supplied to the room by the air supply diffuser, the air is cooled and supplied to a temperature effective for cooling, thereby eliminating the installation of air conditioners in the room, thereby expanding the effective space.

또한 환기에 충분한 공기량과, 냉방에 유효한 공기량이 같게 되어 보다 편리하게 환기와 냉방을 충족할 수 있는 등 여러가지 효과가 있다. In addition, the amount of air sufficient for ventilation and the amount of air effective for cooling are the same, so that the ventilation and cooling can be more conveniently satisfied.
