Description

중앙난방과 가정용 보일러를 병행하는 냉난방장치 및 이의 제어방법{Heating and air-conditioning equipment for central heating and household boilers and control method thereof}A heating and cooling system that combines central heating and a household boiler and a control method thereof

개시되는 내용은 중앙난방과 가정용 보일러를 병행하는 냉난방장치 및 이의 제어방법에 관한 것으로, 더욱 상세하게는 LPG나 LNG 등 도시가스,기름,펠렛등 비교적 값이 비싼 보일러를 보조 열원으로 사용하고, 메인으로 열병합발전, 중앙집중공급열원,화목보일러 등 값싼 연료원이면서 간헐적으로 공급되는 시스템에 난방 또는 냉방 사용을 병행할 수 있도록 하는 것이다. The disclosed content relates to a heating and cooling system that combines central heating and a domestic boiler and a control method thereof, and more specifically, a relatively expensive boiler such as city gas such as LPG or LNG, oil, pellets, etc. as an auxiliary heat source, and the main This is to enable the simultaneous use of heating or cooling in systems that are intermittently supplied and inexpensive fuel sources such as cogeneration, centralized heat source, and firewood boilers.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

아파트 단지 등의 공동주택단지 내에서는 2가지 난방방식을 채택하고 있다. There are two heating methods in multi-unit housing complexes such as apartment complexes.

각 세대에 개별의 난방기를 채용한 개별난방방식과 중앙에서 난방 및 생활온수를 공급하는 중앙난방방식이 있다.There is an individual heating system that employs an individual heater for each household, and a central heating system that supplies heating and domestic hot water from the center.

중앙집중식 난방을 채택하는 열 수요처, 즉 아파트 단지 등의 난방방식은 B-C유, LNG, LPG 등의 연료를 사용하여 물을 가열하고, 가열된 100℃ 이상의 물이나 증기를 1일에 3~5차례 간헐적으로 아파트 단지 내의 각 가정에 온수를 제공하는 것이다.Heat demanders that adopt centralized heating, that is, apartment complexes, use fuels such as B-C oil, LNG, and LPG to heat water, and use heated water or steam at 100°C or higher 3 to 5 times a day. It is to provide hot water to each household in the apartment complex intermittently.

이러한 종래의 중앙집중식 난방방식은 보일러에서 물이나 증기를 생산하고, 생산된 증기를 열교환기를 통해 고온수로 열교환하여 온수로 제공하는 것으로, 이는 대량의 보일러를 사용하게 되고 증기를 온수로 교환하는 열교환 방식으로 열손실이 상당히 많은 것을 볼 수 있다.This conventional centralized heating method produces water or steam in a boiler, and heats the produced steam with high-temperature water through a heat exchanger to provide hot water, which uses a large number of boilers and exchanges steam with hot water. In this way, you can see that the heat loss is quite large.

이를 개선하기 위한 것으로, 에너지 이용효율이 높은 열병합 발전(Combined Heat and Power Plant)시스템이 있다. In order to improve this, there is a combined heat and power plant system with high energy use efficiency.

열병합 발전은 하나의 에너지원으로부터 전력과 열을 동시에 생산하는 종합 에너지 시스템으로 일반적으로 고온부는 동력으로 사용하고, 저온부는 열로 사용하는 에너지 시스템을 운영하고 있다.Combined heat and power generation is a comprehensive energy system that simultaneously produces power and heat from a single energy source. Generally, an energy system is operated in which a high-temperature part is used as power and a low-temperature part is used as heat.

그러나 열병합 발전은 설비용량 대비 열효율이 현저히 떨어질 뿐만 아니라 각 가정에 적정한 온도의 온수(급탕 및 난방)를 제공할 수 없었다. However, combined heat and power generation was not only significantly inferior in thermal efficiency compared to the installed capacity, but also could not provide hot water (hot water supply and heating) at an appropriate temperature to each home.

즉 일부 가정은 난방 온수의 온도가 낮아 사용량이 많아도 충분한 난방효과를 얻을 수 없는 불균형이 있었다. In other words, there was an imbalance in which the heating and hot water temperature of some households was low, so that sufficient heating effect could not be obtained even if the amount of use was large.

2단계) Step 2)

열원에 의한 운전이 가능한 온도일 경우, If the temperature is at which operation by heat source is possible,

[난방가동][Heating operation]

도 2는 실시예에 따른 중앙난방과 가정용 보일러를 병행하는 냉난방장치 및 이의 제어방법의 '난방 가동'을 나타낸 도면이다. FIG. 2 is a view showing 'heating operation' of an air-conditioning device that uses central heating and a home boiler in parallel according to an embodiment and a control method thereof.

외부열원부(100)에서 열이 공급되는 상태에서 주열교환기(3)가 난방을 시행하기 위하여 제어부(22)의 "전원ON/OFF선택KNOB"를 온(ON)하고, "온수전용/난방겸용선택KNOB"를 난방겸용으로 선택하고,"설정대상선택KNOB"를 눌러 온(ON)한 후 설정하고자 하는 난방관수온도를 "관수온도조절dial"를 돌려 설정한다.In order for the main heat exchanger 3 to perform heating in a state in which heat is supplied from the external heat source unit 100, the “power ON/OFF selection KNOB” of the control unit 22 is turned on, and “hot water only/heating combined use” Select “Selection KNOB” for both heating and press “Set target selection KNOB” to turn it on and set the heating water temperature you want to set by turning the “irrigation temperature control dial”.

외부열원선택용 삼방밸브(20)가 제3유로(203)와 제2유로(202)를 통하도록 개방시킨다. The three-way valve 20 for external heat source selection is opened to pass through the third flow path 203 and the second flow path 202 .

배출라인(130)을 통해 외부열원의 열이 외부열원용열교환기(2)에 공급되고, 수조팽창탱크(16)에서 순환펌프(1)를 통해 외부열원용열교환기(2)로 유입되어 열교환에 의해 가열된다. The heat from the external heat source is supplied to the heat exchanger 2 for the external heat source through the discharge line 130, and the heat exchanger 2 for the external heat source flows from the water tank expansion tank 16 through the circulation pump 1 to the heat exchanger 2 for heat exchange. heated by

외부열원용열교환기(2)에서 열교환을 마친 후 외부열원의 열은 비례제어밸브(15)의 개방에 의해 배출된다. After heat exchange is completed in the heat exchanger for an external heat source (2), the heat from the external heat source is discharged by opening the proportional control valve (15).

외부열원용열교환기(2)에서 가열된 온수는 주열교환기(3)로 유입되고, 버너(4)의 온 작동에 의해 가열되어 고온의 난방관수가 생성된다. The hot water heated in the heat exchanger for an external heat source (2) flows into the main heat exchanger (3), and is heated by the on operation of the burner (4) to generate high-temperature heating water.

설정이 완료되면, 주열교환기(3)의 난방공급 온도센서(7)에서 감지된 온도가 난방설정온도보다 낮고, 주열교환기(3)가 가동될 조건(시간선택시 가동시간)에 해당될 경우, When the setting is completed, the temperature sensed by the heating supply temperature sensor 7 of the main heat exchanger 3 is lower than the heating set temperature, and if the main heat exchanger 3 corresponds to the operating conditions (operation time when selecting time),

주열교환기(3)의 메인콘트롤러에서 외부열원용 열교환기(10)의 지역난방측에 설치된 비례제어밸브(19)의 개도를 제어부(22)의 난방 설정온도와 주열교환기에 설치된 난방온도센서(7)에서 감지된 온도차에 의하여 개도를 열어 난방에 필요한 열을 외부열원용 열교환기에서 열교환되어 보일러에 전달되고, 전달된 열은 순환펌프(1)에 의하여 난방비례제어밸브(11)를 거쳐 난방공간에 전달된다.The opening degree of the proportional control valve 19 installed on the district heating side of the heat exchanger 10 for an external heat source in the main controller of the main heat exchanger 3 is determined by the heating set temperature of the controller 22 and the heating temperature sensor 7 installed in the main heat exchanger. ), the heat required for heating is opened by the temperature difference detected in is transmitted to

이때 난방공급온도센서(7)에서 감지된 온도가 난방 설정온도보다 높을 경우에는 난방비례밸브(11)의 개도를 닫는 쪽으로 조절하여 최소 개도를 40%까지 자동 조절하여 난방 유량을 제어하여 배관중 소음 및 난방용량을 조절하여 난방공간의 설정온도를 맞추게 된다. At this time, when the temperature sensed by the heating supply temperature sensor 7 is higher than the heating set temperature, the opening degree of the heating proportional valve 11 is adjusted to the closing side, and the minimum opening degree is automatically adjusted up to 40% to control the heating flow rate to control noise in piping. and adjusting the heating capacity to match the set temperature of the heating space.

이때 난방측의 개도는 항상 처음 가동 시작시에는 100%부터 조절되며, 난방관수 온도가 설정온도에 도달되면 난방리턴온도센서(10)에 의해 감지된 온도와 난방공급센서(7)의 설정온도와의 온도차에 의하여 난방비례밸브(11)의 개도를 자동 조절하여 난방공급과 환수의 온도차를 약10℃ 정도로 조정하여 효율적이고 저소음으로 운전을 실시하게 된다. At this time, the opening degree of the heating side is always adjusted from 100% at the first start of operation, and when the heating water temperature reaches the set temperature, the temperature detected by the heating return temperature sensor 10 and the set temperature of the heating supply sensor 7 and the By automatically adjusting the opening degree of the heating proportional valve 11 by the temperature difference of

외부 열원 이용시는 외부에서 공급되는 열량이 커 난방 가동중에도 온수를 동시에 공급할 수 있다. When an external heat source is used, the amount of heat supplied from the outside is large, so that hot water can be supplied at the same time during heating operation.

주열교환기(3)의 가동 중 주기적으로 열원용 비례제어밸브(19)를 열원감지온도센서(18)가 감지할 수 있도록 개폐한다.During operation of the main heat exchanger (3), the proportional control valve (19) for the heat source is periodically opened and closed so that the heat source detection temperature sensor (18) can detect it.

설정된 온도보다 낮을경우 외부열원이 공급이 되지않는 것으로 판단하여 열원용 비례제어밸브(19)를 닫고, 난방관수온도로 주열교환기(3) 내에 장착된 버너(4), 송풍기(5)를 가동하여 자동으로 외부열원을 대체하여 가동하게 된다.If the temperature is lower than the set temperature, it is judged that the external heat source is not supplied, and the proportional control valve for the heat source is closed (19), and the burner (4) and the blower (5) installed in the main heat exchanger (3) are operated at the heating water temperature. It automatically replaces the external heat source and operates.
