연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An energy-saving heating and hot water supply system includes a main heat exchanger, a circulation pump, a hot water supply heat exchanger and a hot water distributor. The main heat exchanger produces heating water through a heat exchange. The circulation pump circulates the heating water produced in the main heat exchanger so that the heating water is supplied to and collected from each household or floor. The hot water supply heat exchanger produces hot water through a heat exchange between water for hot water supply and the heating water supplied from the main heat exchanger and circulates the produced hot water in a floor coil through the hot water distributor or directly circulates the produced hot water in the floor coil. The hot water distributor receives the heating water and circulates the received heating water in the floor coil provided for each household or floor.

1. An energy-saving central heating and hot water supply system, the system comprising: a main heat exchanger configured to receive one of heat sources among hot water, medium temperature water, and steam from a heat production facility and produce heating water through a main heat exchange;a circulation pump configured to circulate the heating water produced in the main heat exchanger so that the heating water is supplied to and collected from each household or floor;a hot water supply heat exchanger located at each household or floor so as to produce hot water through a hot water supply heat exchange by utilizing the heating water supplied from the main heat exchanger,wherein the produced hot water is circulated in a floor coil through a hot water distributor located at the same household or floor or is directly circulated in the floor coil;an integrated hot water supply main pipe extended from the main heat exchanger so as to supply the produced hot water;an integrated hot water return main pipe extended from the main heat exchanger so as to return the used heating water to the main heat exchanger;a heating water supply pipe configured to connect the integrated hot water supply main pipe to a supply side of the hot water distributor;a heating water return pipe configured to connect the integrated hot water return main pipe to a collection side of the hot water distributor;a heating water supply pipe for hot water supply branched from the heating water supply pipe and connected to the hot water supply heat exchanger;a first valve installed in the heating water supply pipe so as to control a flow path of the heating water supply pipe;a second valve installed in the heating water supply pipe for hot water supply so as to control a flow path of the heating water supply pipe for hot water supply;a controller configured to control the first and second valves to supply the heating water supplied through the heating water supply pipe to the hot water distributor or the hot water supply heat exchanger depending on the present use of the hot water;a bypass pipe configured to return a portion of the heating water supplied from the hot water supply heat exchanger to the hot water distributor to the heating water return pipe by connecting the heating water supply pipe to the heating water return pipe; anda pipeline control unit configured to distribute the heating water discharged from the hot water supply heat exchanger to the hot water distributor and the bypass pipe at a predetermined ratio. 2. The system of claim 1, wherein the pipeline control unit is configured as a proportional control 3-way valve located at a connection portion between the heating water supply pipe and the bypass pipe so as to distribute the heating water to the heating water supply pipe and the bypass pipe based on a value set by the controller. 3. The system of claim 2, wherein the first valve is configured as a constant flow on/off valve for controlling the flow path of the heating water supply pipe so that heating water with a flow rate corresponding to the set value flows through the heating water supply pipe and for opening/closing the flow path of the heating water supply pipe, and the second valve is configured as a constant flow on/off valve for controlling the flow path of the heating water supply pipe for hot water supply so that the heating water with the flow rate corresponding to the set value flows through the heating water supply pipe for hot water supply and for opening/closing the flow path of the heating water supply pipe for hot water supply. 4. The system of claim 1, wherein the pipeline control unit comprises: a constant flow valve installed at an end of the heating water supply pipe so as to control the flow path of the heating water supply pipe so that the heating water with the flow rate corresponding to the set value is supplied to the hot water distributor; anda third constant flow on/off valve installed in the bypass pipe so as to control a flow path of the bypass pipe so that the heating water with the flow rate corresponding to the set value is discharged through the bypass pipe and to open/close the flow path of the bypass pipe. 5. The system of claim 4, wherein the first valve is configured as an on/off valve for opening/closing the heating water supply pipe, and the second valve is configured as a constant flow on/off valve for controlling the flow path of the heating water supply pipe for hot water supply so that the heating water with the flow rate corresponding to the set value flows through the heating water supply pipe for hot water supply and for opening/closing the flow path of the heating water supply pipe for hot water supply. 6. The system of claim 1, further comprising a flow switch installed in a water supply pipe for hot water supply, branched from a water supply pipe extended from a water supply pump and connected to the hot water supply heat exchanger so as to generate a signal for controlling the first and second valves so that the hot water is supplied to the hot water supply heat exchanger by sensing a flow of fluid upon the opening of a water faucet. 7. The system of claim 1, further comprising: a water circulation pipe configured to connect an end of a hot water supply pipe connected to a water faucet from the hot water supply heat exchanger to the water supply pipe for hot water supply so as to circulate the hot water;a hot water circulation pump installed at an end of the water circulation pipe or the water supply pipe for hot water supply so as to circulate the hot water in the pipe;a temperature sensor installed in the water supply pipe for hot water supply or the water circulation pipe so as to detect a temperature of the hot water; anda temperature control circuit unit performing reheating of the hot water by receiving a temperature value of the hot water, inputted by a user, comparing the temperature value inputted by the user with the temperature value detected by the temperature sensor, and, when the detected temperature value is smaller than the inputted temperature value, driving the hot water circulation pump and controlling the first and second valves so that the heating water is supplied to the hot water supply heat exchanger. 8. The system of claim 1, wherein the circulation pump is configured with a plurality of pumps, and the controller has an operation control function of variably controlling the flow rate of the heating water circulated by the circulation pumps depending on the change of calorie, required in each household or floor. 9.
