Description

에너지 절약 컨트롤러{Energy saving controller}Energy saving controller

본 발명은 항온항습에 필요한 실내의 공기조화장치에 설치되어 외기변동에 따라 실내 온습도 설정값을 변경할 수 있는 에너지 절약 컨트롤러에 관한 것으로서, 보다 상세하게는 실내의 허용 온습도 값을 벗어나지 않는 범위 내에서 외기조건과 가장 근접한 실내 온습도 조건을 설정하므로서 가장 적은 비용의 에너지로 항온항습 목적을 달성할 수 있는 에너지 절약 컨트롤러에 관한 것이다.The present invention relates to an energy saving controller installed in an indoor air conditioner required for constant temperature and humidity, and capable of changing an indoor temperature and humidity setting value according to outside air fluctuations. The present invention relates to an energy-saving controller that can achieve the constant temperature and humidity purpose with the lowest cost of energy by setting the indoor temperature and humidity conditions closest to the conditions.

현재 사용되고 있는 일반적인 항온항습기 및 공조장치 등은 외기의 온습도와 관계없이 사계절 동일한 실내 온습도를 유기하기 위하여 여름철에는 실내제습을 위해 냉동기를 가동하여야 하고 겨울철에는 실내 가습을 위해 보일러 가동 및 냉난방가습장치를 연중 가동하므로서 막대한 에너지 비용이 소요되는 문제점이 있다.In general, the thermo-hygrostat and the air-conditioning device currently used should operate a freezer for indoor dehumidification in summer to maintain the same indoor temperature and humidity regardless of the temperature and humidity of the outside air, and operate a boiler and an air-conditioning and humidification device for indoor humidification in winter. There is a problem of enormous energy costs by operating.

대한민국 실용신안등록출원 제 99-9273호에 "항온항습기용 마이컴컨트롤러"가 소개되어 있다. 상기 항온항습기용 마이컴컨트롤러는 실내 온습도값을 감지하여 실내 온습도값과 세팅값을 비교하므서 외기조건과 상관없이 실내 온습도를 항상 일정하게 유지시킨다.Korean Utility Model Registration Application No. 99-9273 introduces "My Com- puter for Thermo-hygrostat". The microcontroller for the thermo-hygrostat senses the indoor temperature and humidity values and compares the indoor temperature and humidity values with the setting values, thereby keeping the indoor temperature and humidity constant at all times.

일반적으로 항온항습실의 경우 온도 조건은 세팅값에서 ±2∼5℃ 그리고 습도조건은 세팅값에서 ±5∼10%의 허용 한계를 가지고 있으며, 이러한 허용한계 내에서 온습도의 변경이 가능하다. 그리고, 항온항습기 또는 공기조화장치가 이러한 허용 한계를 만족하는 최소한의 운전만을 수행할 경우 다량의 에너지 비용을 절감할 수 잇는 효과가 있으나, 상기 항온항습기용 마이컴 컨트롤러의 경우 외부공기의 조건에 따라 수시로 온습도값을 수동으로 세팅해야 번거로운 문제점이 있었다.In general, in the case of a constant temperature and humidity room, the temperature conditions have a tolerance of ± 2 to 5 ° C at the set value and the humidity conditions at ± 5 to 10% at the set value, and the temperature and humidity can be changed within these tolerances. In addition, if the thermo-hygrostat or the air conditioner performs only the minimum operation that satisfies these allowable limits, the energy cost can be reduced. Manually setting the temperature and humidity value had a problem.

따라서, 본 발명의 목적은 실내의 허용 온습도 값을 벗어나지 않는 범위 내에서 외기조건과 가장 근접한 실내 온습도 조건을 설정하므로서 가장 적은 비용의 에너지로 항온항습 목적을 달성할 수 있는 에너지 절약 컨트롤러를 제공하는 것이다.Accordingly, an object of the present invention is to provide an energy-saving controller that can achieve the constant temperature and humidity objectives with the lowest cost of energy by setting the indoor temperature and humidity conditions closest to the outside conditions within the range without departing from the allowable temperature and humidity values of the room. .

상기와 같은 목적을 달성하기 위한 본 발명에 따른 에너지 절약 컨트롤러의 일례는 외기 온습도 검출기로부터 외부공기의 온도 및 습도값을 받아 실내 온습도제어기의 현재의 세팅값과 외기의 온습도값을 비교 연산하여 항온항습기가 최소한의 에너지로 운전할 수 있는 실내 온습도값을 연산하여 상기 연산된 실내 온습도값을 실내 온습도 제어기로 전송하여 상기 실내 온습도 제어기의 세팅값을 변경하는 것을 특징으로 한다.An example of the energy saving controller according to the present invention for achieving the above object is to receive a temperature and humidity value of the outside air from the outside temperature and humidity detector to compare and calculate the current setting value of the room temperature and humidity controller and the temperature and humidity value of the outside air temperature and humidity controller Calculates an indoor temperature and humidity value capable of operating with minimal energy, and transmits the calculated indoor temperature and humidity value to an indoor temperature and humidity controller to change the setting value of the indoor temperature and humidity controller.

1 : 에너지 절약 컨트롤러 3 : 외기 온습도 검출기1: energy saving controller 3: outside temperature and humidity detector

5 : 실내 온습도 제어기5: indoor temperature and humidity controller

도 1을 참조하면, 본 발명에 따른 에너지 절약 컨트롤러(1)는 외기 온습도 검출기(1)로부터 외부공기의 온도 및 습도값을 받아 실내 온습도 제어기(5)의 현재의 세팅값과 외기의 온습도값을 비교 연산하여 항온항습기(도시하지 않음)가 최소한의 에너지로 운전할 수 있는 실내 온습도값을 연산하여 상기 연산된 실내 온습도값을 실내 온습도 제어기(5)로 전송하여 상기 실내 온습도 제어기(5)의 세팅값을 변경한다.1, the energy saving controller 1 according to the present invention receives the temperature and humidity value of the outside air from the outside temperature and humidity detector 1 to determine the current setting value of the room temperature and humidity controller 5 and the temperature and humidity value of the outside air. Comparing and calculating a room temperature and humidity value at which a thermo-hygrostat (not shown) can operate with minimal energy, and transmits the calculated room temperature and humidity value to the room temperature and humidity controller 5 to set the value of the room temperature and humidity controller 5. To change.

상기 에너지 절약 컨트롤러(1)는 온도 및 습도를 엔탈피값으로 연산하여 실내 한계치에 가까운 온습도값을 설정할 수 있다.The energy saving controller 1 may set the temperature and humidity value close to the indoor limit by calculating the temperature and humidity as enthalpy values.

위에서 설명한 본 발명에 따른 에너지 절약 컨트롤러를 이용하여 외기조건에 따른 항온항습기 또는 공기조화장치의 최소 운전을 하였을 경우 에너지가 절약되는 예는 다음과 같다.The energy saving controller according to the present invention using the energy saving controller according to the present invention when the minimum operation of the thermo-hygrostat or the air conditioner according to the external conditions is as follows.

하계 냉방시, 예컨대 외기조건이 33℃, 55% RH이고, 세팅값이 22℃, 50% RH일 경우, 에너지 절약 컨트롤러는 26.5℃, 67.8% RH로 연산된다. 그러나, 상한값이 25℃, 60% RH인 경우, 상기 에너지 절약 컨트롤러는 25℃, 60% RH값을 실내 온습도제어기(5)로 전송하여 설정값을 세팅한다.During summer cooling, for example, when the outdoor air condition is 33 ° C. and 55% RH and the setting value is 22 ° C. and 50% RH, the energy saving controller calculates 26.5 ° C. and 67.8% RH. However, if the upper limit value is 25 ° C, 60% RH, the energy saving controller transmits the 25 ° C, 60% RH value to the room temperature and humidity controller 5 to set the set value.

이와같이 하계 냉방시 온습도 설정값을 변경할 경우, 냉각수 코일 전후의 엔탈피차는 초기 세팅을 유지할 경우 5. 3kcal/kg이고, 상한값을 설정하지 않은 경우 2.1kcal/kg이며, 상한값이 설정된 경우 3.2kcal/kg으로 항온항습기 또는 공기조화장치의 사용 에너지를 절약할 수 있다.Thus, when changing the temperature and humidity setting value during summer cooling, the enthalpy difference before and after the coolant coil is 5. 3 kcal / kg when maintaining the initial setting, 2.1 kcal / kg when the upper limit is not set, and 3.2 kcal / kg when the upper limit is set. Energy savings can be saved in the thermo-hygrostat or air conditioner.

동계 난방시, 예컨대 외기조건이 0℃, 60% RH이고, 세팅값이 22℃, 50% RH일 경우, 에너지 절약 컨트롤러는 18℃, 30% RH로 연산된다. 그러나, 상한값이 19℃, 40% RH인 경우, 상기 에너지 절약 컨트롤러는 25℃, 60% RH값을 실내 온습도 제어기(5)로 전송하여 설정값을 세팅한다.In the case of winter heating, for example, when the external air condition is 0 ° C. and 60% RH and the setting value is 22 ° C. and 50% RH, the energy saving controller is calculated at 18 ° C. and 30% RH. However, if the upper limit value is 19 ° C. and 40% RH, the energy saving controller transmits the 25 ° C. and 60% RH value to the room temperature and humidity controller 5 to set the set value.

이와같이 동계 난방시에도 온습도 설정값을 변경할 경우, 항온항습기 또는 공기조화장치의 사용 에너지를 상당히 절약할 수 있다.Thus, if the temperature and humidity setting value is changed even during winter heating, the energy used by the thermo-hygrostat or the air conditioner can be significantly saved.

위에서 설명한 바와같이 본 발명에 따른 허용 온습도 값을 벗어나지 않는 범위 내에서 외기조건과 가장 근접한 실내 온습도 조건을 설정하므로서 가장 적은 비용의 에너지로 항온항습 목적을 달성할 수 있는 효과가 있다.As described above, by setting the indoor temperature and humidity conditions closest to the outside conditions within the range without departing from the allowable temperature and humidity values according to the present invention, there is an effect of achieving the constant temperature and humidity objectives with the lowest cost of energy.
