In addition, by using waste heat of cooling water for cooling the condenser of a turbine generator as a heat source, the temperature of cooling water is lowered while passing an evaporator of the absorption heat pump, and by using the cooling water with lowered temperature as cooling water for the condenser, the efficiency of the turbine generator is improved as the temperature of the condenser is lowered, and, therefore, electricity output can be increased.

Description

전기 및 열 생산량 증대를 위한 흡수식 히트펌프가 구비된 지역 난방시스템{DISTRICT HEATING SYSTEM INCLUDING ABSORPTION HEAT PUMP FOR INCREASING PRODUCTION AMOUNT OF ELECTRICITY AND HEAT}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a district heating system having an absorption type heat pump for increasing electricity and heat production.

본 발명은 전기 및 열 생산량 증대를 위한 흡수식 히트펌프가 구비된 지역 난방시스템에 관한 것으로서, 상세하게는 지역난방 공급측의 고온수를 흡수식 히트펌프의 재생기로 공급하여 재생열로 활용하고, 지역난방 회수측으로부터 저온의 난방수를 흡수식 히트펌프 흡수기로 공급하여 재생기로부터 공급된 흡수액과 열교환되어 1차 가열되고, 응축기를 통과하면서 2차 열교환되도록 하여 온도를 승온시켜 배열회수 보일러의 디에이치 이코너마이저(DH Economizer) 또는 열전용 보일러의 입구 온수온도를 상승시킴으로서 열생산을 증가시키고, 터빈 발전기의 복수기의 냉각을 위한 냉각수의 폐열을 열원으로 활용하여 흡수식 히트펌프의 증발기를 거치면서 냉각수의 온도가 저감되므로 이 저감된 냉각수를 복수기의 냉각수로 활용하도록 하는 전기 및 열 생산량 증대를 위한 흡수식 히트펌프가 구비된 지역 난방시스템에 관한 것이다.The present invention relates to a district heating system equipped with an absorption type heat pump for increasing electricity and heat production. More particularly, the present invention relates to a district heating system for supplying hot water at a district heating supply side to a regenerator of an absorption type heat pump, The heat of the low temperature is supplied to the absorption heat pump absorber, and the heat is exchanged with the absorption liquid supplied from the regenerator to be firstly heated, and the secondary heat exchanger is allowed to pass through the condenser to raise the temperature, DH Economizer) or by increasing the temperature of the hot water at the inlet of the heat-only boiler and by using the waste heat of the cooling water for cooling the condenser of the turbine generator as a heat source, the temperature of the cooling water is reduced while passing through the evaporator of the absorption heat pump Electricity and heat that make this reduced cooling water to be used as the cooling water of the plural Relates to a district heating system is provided with an absorption heat pump for increasing the acid amount.

일반적으로 지역난방시스템은 집단에너지를 공급하는 사업자가 다수의 개별 사용자에게 난방 및 급탕을 위해 배관을 통해 집단에너지를 공급하는 시스템으로 개별적으로 사용자가 난방설비를 갖추는 개별난방 시스템과는 차이가 있다.Generally, district heating system differs from individual heating system in which the user who supplies the collective energy supplies the collective energy through piping for heating and hot water supply to a large number of individual users.

즉, 지역난방은 한 개의 도시 또는 일정한 지역 내에 있는 주택, 상가, 사무실, 학교, 병원, 공장 등 각종 건물이 개별적으로 난방설비를 갖추지 않고, 대규모 열생산시설, 즉 열병합발전소를 건설하여 난방 및 급탕에 필요한 중온수(80~120℃)를 생산, 열수송관을 통해 각 수용가에 공급하는 시스템으로 집단에너지 공급방식 중 하나이다.In other words, district heating does not have individual heating facilities such as houses, commercial buildings, offices, schools, hospitals, factories, etc. in a single city or a certain area, and a large-scale heat production facility, that is, a cogeneration power plant, (80 ~ 120 ℃), which is needed to supply electricity to the customers through the heat transfer pipe.

그러나, 이러한 지역 난방시스템은 터빈으로부터 나오는 스팀을 열교환기로 통과시키면서 축열조로부터 공급되는 온수와 열교환하여 승온시켜서 지역 난방수로 공급하기 때문에, 열병합발전소의 발전능력을 저하시키는 요인으로 작용하였다.However, such a district heating system causes the steam generated from the turbine to pass through the heat exchanger, heat-exchanges heat with the hot water supplied from the heat storage tank, and then supplies the steam to the district heating water.

최근에는 발전소나 산업시설의 냉각탑 등에서 버려지는 폐열을 회수하기 위한 방법으로 흡수식 히트펌프를 이용하여 지역난방수를 가열하기 위한 방법이 제안되고 있다. Recently, a method for heating the district heating water using an absorption type heat pump has been proposed as a method for recovering the waste heat that is thrown away from a cooling tower of a power plant or an industrial facility.

국내 특허등록공보 10-975276호(히트펌프를 이용한 지역난방수 공급시스템)과, 10-1052776호(열교환기를 포함하는 고효율 흡수식 히트펌프를 이용한 지역난방수 가열시스템)이 출원되어 등록되어 있다.Korean Patent Registration No. 10-975276 (local heating water supply system using a heat pump) and 10-1052776 (local heating water heating system using a high efficiency absorption heat pump including a heat exchanger) are filed and registered.

상기 히트펌프를 이용한 지역난방수 공급시스템은 지역 난방수가 흡수기를 거치면서 재생기로부터 공급된 흡수액과 열교환 되어 1차 가열되고, 재생기에서 발생된 고온의 냉매증기에 의해 응축기를 거치면서 2차 가열되어 공급되도록 되어 있다.In the district heating water supply system using the heat pump, the district heating water is heat-exchanged with the absorption liquid supplied from the regenerator while passing through the absorber, and is firstly heated. The high-temperature refrigerant vapor generated in the regenerator is secondarily heated .

그러나 상기 히트펌프를 이용한 지역난방수 공급시스템은 1차로 흡수기에서 가열되고 2차로 응축기에서 가열되어 배출되는 난방수가 지역난방에 사용할 수 있는 온도(약 105℃)이상으로 충분히 가열되지 못하고, 히트펌프에서 냉매가 고농도로 인하여 결정화되어 효율이 떨어지는 문제점이 있다.However, in the district heating water supply system using the heat pump, the heating water, which is heated by the absorber in the first stage and secondarily heated by the condenser, can not be sufficiently heated to a temperature (about 105 ° C) There is a problem that the refrigerant is crystallized due to the high concentration and the efficiency is lowered.

또한 상기 열교환기를 포함하는 고효율 흡수식 히트펌프를 이용한 지역난방수 가열시스템은 터빈으로부터 스팀을 추기하여 흡수식 히트펌프의 재생열로 활용하기 때문에 스팀 추기로 인해 발전 출력이 저하되는 문제점이 있다.Also, since the district heating water heating system using the high efficiency absorption heat pump including the heat exchanger adds steam from the turbine and uses the steam as the regeneration heat of the absorption heat pump, there is a problem that the power generation output decreases due to steam addition.
