Description

LED 수위레벨 게이지를 이용한 축냉량 제어방법{omitted}Method for controlling axial flow rate using LED level level gauge {omitted}

본 발명은 LED 수위레벨 게이지를 이용한 축냉량 제어방법에 관한 것으로, 더욱 상세하게는 축냉조 내부에는 결빙되는 축냉재의 축냉량 증감에 따라 실외기의 가동을 제어하여 빙축열 에어컨의 손상을 방지하고, 사용자가 실내에서 축냉량을 확인할 수 있도록 하여 에어컨의 부하운전을 효율적으로 제어할 수 있도록 하며, 축냉량 센서의 신뢰성을 향상시키고 정확한 축냉량을 표시하기위해 LED 수위레벨 게이지를 이용한 축냉량 제어방법에 관한 것이다.[0001] The present invention relates to a method of controlling an axial flow rate using an LED level gauge, and more particularly, to a method of controlling an axial flow rate of an indoor unit by controlling the operation of an outdoor unit according to an increase / To control the load operation of the air conditioner by allowing the user to check the axial flow rate in the room, to improve the reliability of the axial flow rate sensor and to display the accurate axial flow rate by using the LED level gauge will be.

일반적으로 빙축열 에어컨은 심야의 경부하 수요시간 동안 잉여전기를 이용하여 얼음을 얼려 축냉조에 저장하였다가 냉방부하가 커지는 주간에 축냉조에 저장된 얼음을 이용하여 실내의 냉방을 수행하는 장치이다. 이 빙축열 에어컨을 이용할 경우 주간 전력에 비해 저렴한 요금으로 냉방을 행하기 때문에, 전력공급업체에는 전력소비의 억제효과와 심야의 잉여전기의 활용을 가능케 하고, 사용자에게는 보다 저렴한 운전비로 냉방을 행할 수 있는 이점이 있다.Generally, the ice-cooled thermal air conditioner is a device for cooling indoor space by using the ice stored in the cold storage during the day when the ice is frozen and stored in the cold storage during the nighttime light-demand period using the surplus electricity. In the case of using the ice storage heat air conditioner, the cooling is performed at a cheaper rate compared to the daytime electric power. Therefore, the electric power supplier can utilize the effect of suppressing the electric power consumption and the surplus electricity at the late night, There is an advantage.

이러한 빙축열 에어컨은 크게 실외기, 축냉조 및 실내기를 포함하여 이루어진다. 이러한 빙축열 에어컨에 있어서, 야간에 실외기를 가동하면 압축기의 구동에 의해 순환하는 냉매가, 축냉재(물)가 충전된 축냉조에 설치된 열교환코일을 거치면서 축냉조 내부의 축냉재와 열교환됨에 따라 축냉재가 냉각되어 얼음이 점차 형성된다. 즉, 실외기의 가동시간이 증가함에 따라 얼음의 체적은 점차 증가한다. 이와 같이 얼음이 된 상태에서 주간에 상기 축열조 내부의 얼음으로부터 해빙된 차가운 축냉재가 순환펌프의 작동에 의해 축냉조와 실내기를 순환함에 따라 실내기의 표면을 거쳐 실내로 송풍되는 공기와 축냉재가 열교환됨으로써 실내의 냉방이 수행된다.Such an ice storage heat air conditioner largely includes an outdoor unit, a cold storage unit, and an indoor unit. In such an ice-cooled thermal air conditioner, when the outdoor unit is operated at night, the refrigerant circulated by the compressor is heat-exchanged with the axial coolant in the axial cold storage while passing through the heat exchange coil installed in the axial cold storage filled with the axial cold water The cold material is cooled and ice gradually forms. That is, as the operating time of the outdoor unit increases, the volume of the ice gradually increases. As a result of the circulation of the cold coolant thawed from the ice in the heat storage tank in the ice state during the day, the air blown into the room through the surface of the indoor unit and the coolant are heat exchanged Thereby cooling the room.

이러한 빙축열 에어컨에 있어서, 심야에 실외기의 가동시간이 길어지면 얼음의 부피가 점차 증가함에 따라 얼음을 포함하는 축냉재의 부피가 얼지 않았을 때의 축냉재의 부피보다 증가한다. 이 부피의 증가에 의해 축냉조 또는 축냉조에 설치된 부품들이 손상될 우려가 있다. 또한, 얼음이 일정부피 이상 형성된 후에도 계속 실외기를 가동하게 되면 전력의 낭비가 커지게 되는 등의 문제점도 있다.In such an ice-cooled thermal air conditioner, as the volume of the ice gradually increases as the operation time of the outdoor unit becomes longer at the midnight, the volume of the freezing material containing ice increases more than the volume of the freezing material. This increase in volume may cause damage to the components installed in the axial chiller or the axial chiller. In addition, there is a problem that when the outdoor unit is continuously operated even after the ice is formed over a certain volume, wasted power is increased.

이러한 점을 고려하여, 종래 축냉조 내부의 결빙상태에 따라 실외기의 가동을 자동으로 제어할 수 있는 기술들이 제안되었다. 그 대표적인 것으로 국내 등록실용신안 제 218472호(특허문헌 1)에 개시된 빙축조의 제빙 제한을 위한 신호 검출방법과, 국내 등록실용신안 제 225076호(특허문헌 2)에 개시된 소형 빙축열 설비용 제빙량 제어장치, 극네 등록실용신안 제 0278219호(특허문헌3)에 개시된 제빙량 제어장치를 들 수 있다.In consideration of this point, techniques have been proposed that can automatically control the operation of the outdoor unit according to the icing condition inside the conventional axial cold storage unit. As a representative example thereof, there is disclosed a signal detection method for icing restriction of ice structure disclosed in Korean Utility Model No. 218472 (Patent Document 1) and ice making amount control for a small ice storage facility disclosed in Korean Registered Utility Model No. 225076 (Patent Document 2) Device, and an ice maker amount control device disclosed in the Utility Model No. 0278219 (Patent Document 3).

특허문헌 1은, 축냉조 내 전열관의 표면으로부터 형성되는 얼음과 접할 수 있는 임의의 제빙 제한선 위치에 감온소자를 장치하여 얼음의 온도를 인식하여 실외기의 가동을 제어하도록 이루어진다. 특허문헌 2는 얼음의 온도를 측정/감지하기 위해 축냉조 내부 일측에 적어도 하나의 온도센서 어셈블리를 설치하여, 감지된 온도와 설정온도를 비교함으로써 실외기의 가동을 제어하도록 이루어진다. 특허문헌 3은 축냉조 내에 얼음이 제빙됨에 따라 증가되는 물수위를 측정하여 실외기 가동을 제어하도록 이루어진다. 즉, 특허문헌 1,2는 공히 축냉조의 내부온도에 따라 실외기의 가동을 제어하도록 이루어진 것이고, 특허문헌 3은 물수위에 따라 실외기 가동을 제어하도록 이루어진 것이다.Patent Document 1 is configured to control the operation of the outdoor unit by recognizing the temperature of the ice by installing a temperature sensing element at an arbitrary freezing limit line position capable of contacting ice formed from the surface of the heat transfer tube in the axial cold storage tank. In Patent Document 2, at least one temperature sensor assembly is installed on one side of the interior of the cooling / cooling tank to measure / detect the temperature of the ice, and the operation of the outdoor unit is controlled by comparing the detected temperature with the set temperature. Patent Document 3 is configured to control the operation of the outdoor unit by measuring the water level which is increased as the ice is ice-cooled in the cold storage tank. That is to say, Patent Documents 1 and 2 are designed to control the operation of the outdoor unit according to the internal temperature of the shaft cold storage, and Patent Document 3 controls the operation of the outdoor unit according to the water level.

그러나, 상기한 바와 같은 축냉조에 대한 온도측정에 의해 실외기의 가동을 제어하는 기술들에 있어서는, 대류현상에 의해 축냉조의 내부 온도가 깊이 및 열교환코일로부터의 거리변화에 따라 다르기 때문에 실외기의 가동제어를 효과적으로 달성하기 어렵다. 더욱이, 얼음의 부피가 증가함에 따라 얼음을 포함한 축냉재의 전체 부피증가량을 알 수 없기 때문에 축냉재의 팽창에 의해 시스템이 손상되는 현상을 방지할 수 없는 문제점이 있다. 또한, 축냉조 내부의 잔빙량을 알수 없기 때문에 에어컨 가동중 축냉량이 떨어져 더운 바람이 나오는 현상이 발생할 수 있다. 또한, 물수위를 외부에서 측정하는 방식은 외부충격(바람등)에 의한 수면 움직임에 의해 오작동이 발생하는 문제점이 있다.However, in the technologies for controlling the operation of the outdoor unit by the temperature measurement for the axial cold storage as described above, since the internal temperature of the axial cold storage unit varies depending on the depth and the distance from the heat exchange coil due to the convection phenomenon, It is difficult to effectively achieve the control. Furthermore, as the volume of the ice increases, the amount of increase in the total volume of the freezing material including ice can not be known. Therefore, there is a problem that damage to the system due to the expansion of the freezing material can not be prevented. In addition, since the amount of remaining ice in the cold storage tank can not be known, a phenomenon may occur in which the cooling capacity of the air conditioner is lowered during operation of the air conditioner and hot air is blown out. In addition, the method of measuring the water level from the outside has a problem that a malfunction occurs due to the movement of the water due to an external impact (wind or the like).
