Description

복합센서를 이용한 쾌적공조장치{Optimal air conditioning control apparatus using multisensor unit}Optimum air conditioning control apparatus using multisensor unit}

본 발명은 복합센서를 이용한 쾌적공조장치에 관한 것으로 이산화탄소 센서를 포함하는 온도, 습도, 복사열, 기류 측정이 가능한 복합센서모듈(1)과 온열환경, 외기냉난방 및 CO2농도를 제어하는 제어모듈(2) 및 제어모듈에 의해 조절되는 공조장치부(2)로 구성된 쾌적공조장치에 관한 것이다.The present invention relates to a comfortable air conditioner using a composite sensor, a composite sensor module (1) capable of measuring the temperature, humidity, radiant heat, air flow, including a carbon dioxide sensor and a control module for controlling the thermal environment, outside air-conditioning heating and CO 2 concentration ( 2) and the air conditioner unit 2 which is controlled by the control module.

현재 일반건물에 설치되어 있는 기존 공조장치는 대부분 온열환경 즉 온도, 습도, 기류를 기초로 운영하고 있다. 종래의 공조장치에 사용되는 체감센서는 기본적으로 인간의 체온 조절기구를 모듈화한 것으로, 주로 기류나 습도, 착의량을 변수로 하여 인간이 느끼는 체감온도를 모의하여 추정하거나 여기에 습도센서 모듈을 추가한 센서를 적용하고 쾌적지수를 산출하여 공조장치에 사용하여왔다. 상기와 같은 공조장치는 재실자에게 CO2가스를 비롯한 다른 오염인자를 그대로 노출시키고 있으며, 온열쾌적조건에서도 정정한 제어가 곤란하여 실내에서 생활하는 재실자가 불쾌감을 느낄 수 있기 때문에 인체 쾌적성 부분에서 많은 보완이 필요한 실정이다.Currently, the existing air conditioners installed in general buildings are operated based on the thermal environment, that is, temperature, humidity, and airflow. The sensory sensor used in the conventional air conditioning system is basically a module of the human body temperature control mechanism, and mainly simulates the sensory temperature felt by humans based on airflow, humidity, and the amount of wear, or adds a humidity sensor module to it. One sensor has been applied and the comfort index has been used for air conditioning systems. Such an air conditioner exposes other contaminants such as CO 2 gas to the occupants as they are, and it is difficult to correct the control even under warm and comfortable conditions, so that the occupants living indoors may feel unpleasant. Complementary situation is needed.

본 발명자들은 상기와 같은 점을 착안하여 인간이 실제 거주하는 공간에 인체의 온열환경요소인 실내의 온도, 습도, 풍속, 복사열의 4가지 온열환경인자를 측정하여 인간이 가장 쾌적하게 느끼는 쾌적 범위를 수치로 도출함과 동시에 CO2의 농도를 측정하여 재실공간과 비재실공간을 구분하여 공조함으로써 최적 실내환경 유지 및 에너지 사용의 합리화와 더불어 불필요한 외기도입이나 실내환경제어를 억제함으로써 에너지 절약을 도모함을 목적으로 한다.In view of the above, the present inventors measure the four thermal environment factors such as temperature, humidity, wind speed, and radiant heat, which are elements of the human body's thermal environment, in the space where humans actually live, to determine the comfort range that humans feel most comfortable. By deriving the numerical value and measuring the concentration of CO 2, it is possible to separate and co-operate the occupied and non-residence spaces to maintain the optimal indoor environment, to rationalize the use of energy, and to save energy by suppressing unnecessary outdoor airflow or indoor environment control. The purpose.

Manufacturing a complex sensor module (1) consisting of a microcomputer 20, a wireless data transmission and reception unit 30 and the display unit 40 for converting the signal into a digital and receives a signal output from the composite sensor module (1) In (2), control of the air conditioning unit (3) by sending a command through a BACnet or building automation system to present CO 2 generated from occupants in public health management and building law.
