Description
본 발명은 히트펌프를 이용한 냉난방 및 온수급탕시스템에 관한 것으로, 특히 하나의 히트펌프를 사용하여 사무실, 가정, 공장, 연구소, 상가 등에서 냉난방 및 온수급탕이 동시에 가능하도록 한 것이다.The present invention relates to a heating and cooling system using a heat pump and a hot water supply system, and in particular, to enable heating and heating and hot water supply at the same time in an office, a home, a factory, a research institute, a mall, and the like by using one heat pump.
히트펌프를 이용한 냉난방시스템에 관한 기술은 이미 공지되어 있다.Techniques for cooling and heating systems using heat pumps are already known.
한편, 종래의 히트펌프를 이용한 냉난방 시스템에 있어서는 냉방모드 또는 난방모드로의 전환밖에 이루어지지 않았었으며, 냉난방과 동시에 온수급탕을 가능하게 한 기술로서는 실용신안공개 제85-5276호의 삼방변을 이용한 수열원히트펌프의 배관구조, 특허공개 제95-1218호의 벌마이어 히트펌프의 냉난방장치가 알려져 있다.Meanwhile, in the conventional heating and cooling system using a heat pump, only the switching to the cooling mode or the heating mode has been achieved. As a technology that enables hot water hot water supply at the same time as cooling and heating, hydrothermal using three sides of Utility Model Publication No. 85-5276 is disclosed. The piping structure of a one-heat pump and the heating and cooling apparatus of the Bulmeier heat pump of Unexamined-Japanese-Patent No. 95-1218 are known.
히트펌프를 이용한 냉난방 및 온수급탕 시스템 구현시 가장 중요한 사항은 초기부하의 적절한 대응성이다. 즉, 단열이 잘 된 적정용량의 저장탱크에 원하는 온도의 물을 축열 혹은 축냉 시켰다가 시초 가동 즉시 과부하상태인 초기부하를 처리하는 방법을 취해야만 수요자가 원하는 부하를 처리할 수 있다. 일반 보일러의 경우는 초기 과부하를 처리할 수 있게끔 충분한 기기용량으로 설정하여도 시설비가 그리 많이 들지 않지만 히트펌프의 경우는 과부하를 전부 대응할 수 있도록 그 용량을 설정하면 설비비가 급격히 증가하므로 본 발명에서는 정상적 부하처리 용량에약간의 여유만을 두어 히트펌프의 용량을 결정하고 최적시스템을 구축하여 그 투자비를 최소화 하고자 한다. 냉방시에는 본 축냉탱크에 저장된 냉수를 곧장 공급 받음으로써 역시 초기 냉방과부하 처리에 보다 능동적으로 대처할 수 있어 기존의 히트펌프나 에어컨 시스템 보다도 훨씬 효율적이다. 상기한 종래의 기술에서는 이러한 초기부하 대응성이나 설비비의 감소를 주목적으로 발명된 것이 아니고 냉난방과 온수급탕 동시기능 발휘에 초점을 맞추고 있으므로 실제 응용할 수 있는 폭이 제약을 받을 수 밖에 없다.The most important thing in implementing heating and cooling system and hot water supply system using heat pump is proper response of initial load. In other words, the user can handle the desired load only by storing or storing the temperature of the desired temperature in a well-insulated storage tank with proper temperature and handling the initial load which is overloaded. In the case of a general boiler, even if it is set to a sufficient capacity to handle the initial overload, it does not cost much, but in the case of a heat pump, if the capacity is set so that it can cope with all the overload, the equipment cost increases rapidly, so it is normal in the present invention. With a slight margin in the load handling capacity, the capacity of the heat pump is determined and the optimal system is established to minimize the investment cost. When cooling, the cold water stored in this storage tank is directly supplied, and thus it is able to cope more actively with initial cooling overload treatment, which is much more efficient than the existing heat pump or air conditioning system. In the above-described conventional technology, the initial load responsiveness and the reduction of the equipment cost are not mainly invented, but the focus is on the simultaneous heating and cooling and hot water supply function.
본 발명은 상기한 종래의 제반 문제점을 해소하기 위하여 안출된 것으로, 본 발명의 목적은 냉난방과 온수급탕을 각각 별도의 히트펌프를 사용하지 않고 1대의 히트펌프 시스템으로 가능토록 운전제어의 최적화를 도모하여 가동초기의 과부하를 능동적으로 처리한다. 특히 냉난방부하에 비해 상대적으로 작은 온수급탕부하를 갖는 사무실이나, 가정, 공장, 연구소, 상가 등에서 냉난방 및 온수급탕을 위한 초기 설비 투자비를 획기적으로 낮출 수 있도록 하는데 있다.The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to optimize the operation control to enable one heat pump system without using a separate heat pump for heating, heating and hot water supply. Actively deal with overload of initial operation. In particular, the office, home, factory, research institute, shopping mall, etc. having a relatively small hot water supply load compared to the heating and cooling load to significantly lower the initial investment cost for heating and heating hot water supply.
이와 같은 목적을 달성하기 위하여 본 발명은 히트펌프와, 이 히트펌프에 접속되는 입수 및 출수라인과, 이 입수 및 출수라인이 연결되어 냉방 또는 난방을 위한 냉온수가 저장되는 냉온수저장탱크와, 상기 입수 및 출수라인과 연결되어 급탕용 온수가 저장되는 온수급탕탱크와, 상기 냉온수저장탱크에 접속되어 실내의 바닥난방이나 냉온풍을 발생시키기 위한 냉난방부와, 상기 출수라인에 설치되는 순환펌프와, 상기 냉온수저장탱크와 냉난방부사이에 설치되는 냉온수순환펌프와, 상기 히트펌프와 냉온수저장탱크 사이의 입수라인에 설치되는 냉난방전자밸브와, 상기 히트펌프와 온수급탕탱크 사이의 입수라인에 설치되는 급탕전자밸브와, 상기 히트펌프의 출수라인에 설치된 탱크순환펌프와 냉온수저장탱크 및 온수급탕탱크 사이에 설치되는 3방전자밸브와, 상기 냉온수저장탱크와 냉난방부사이에 설치된 냉온수순환펌프의 구동을 제어하여 실내온도조절을 하는 실내온도조절기와, 이 모든 작동기기들을 제어하는 제어기를 포함하여 이루어지는 히트펌프를 이용한 냉난방 및 온수급탕시스템을 제공한다.In order to achieve the above object, the present invention provides a heat pump, an inlet and an outlet line connected to the heat pump, a cold and hot water storage tank in which the inlet and outlet lines are connected to store cold and hot water for cooling or heating, and the inlet.

이와 같이 구성된 본 발명은 냉난방시에는 제어기(12)에서 설정된 냉온수저장탱크(4)의 온도에 따라 히트펌프(1)가 가동되어 여기에서 열교환된 냉수 또는 온수가 출수라인(3)의 탱크순환펌프(7)에 의해 3방전자밸브(V3)를 거쳐 냉온수저장탱크(4)에 저장되게 되며, 여기에 저장된 냉수 또는 온수는 실내온도조절기(9)의 조작에 의해 연동되는 냉온수순환펌프(8)에 의해 바닥배관(6a)또는 팬코일유니트 (6b)로 공급되어 실내의 냉방 또는 난방이 이루어지게 된다. 냉방시에는 바닥배관 (6a)입구에 있는 밸브를 닫아 바닥으로는 실제 냉수가 흐르지 않도록 한다.In the present invention configured as described above, the heat pump 1 is operated in accordance with the temperature of the cold / hot water storage tank 4 set by the controller 12 during the heating and cooling. (7) is stored in the cold and hot water storage tank (4) via the three-discharge valve (V3), the cold or hot water stored therein cold and hot water circulation pump (8) interlocked by the operation of the room temperature controller (9) It is supplied to the bottom pipe 6a or the fan coil unit 6b by the cooling or heating of the room is made. When cooling, close the valve at the inlet of the bottom pipe (6a) so that no actual cold water flows to the floor.
한편, 온수급탕시에는 제어기(12)에서 설정된 온수급탕탱크(5)의 온도에 따라 히트펌프(1)에서 열교환을 이룬 온수가 탱크순환펌프(7)에 의해 3방전자밸브 (V3)를 거쳐 온수급탕탱크(5)로 공급되어 욕실이나 주방의 급수구로 공급된다.On the other hand, in the case of hot water hot water, the hot water that has undergone heat exchange in the heat pump 1 according to the temperature of the hot water hot water tank 5 set by the controller 12 is passed through the three discharge valve V3 by the tank circulation pump 7. The hot water supply tank (5) is supplied to the water supply port of the bathroom or kitchen.
상기 냉온수저장탱크(4)와 온수급탕탱크(5)는 도면상으로는 도시하지 않았으나, 그 외부에 단열처리를 함으로써 축열기능을 갖도록 하여 히트펌프(1)의 초기가동시 부하가 크게 걸리는 것을 방지할 수 있도록 한다.Although the cold and hot water storage tank 4 and the hot water hot water tank 5 are not shown in the drawings, the outside of the heat treatment process to have a heat storage function to prevent a large load is applied during the initial operation of the heat pump (1). Make sure
상기한 온수급탕모드 및 냉난방모드는 각 탱크(4,5)의 온도설정값에 의해 자동으로 절환될 수 있도록 하고, 동일 운전조건시에는 온수급탕탱크(5)의 온도설정값이 우선되어 히트펌프(1)는 온수급탕모드로 우선가동되도록 한다. 이는 냉난방과 온수급탕 부하가 동시에 걸릴 때 사용자의 우선요구가 온수급탕에 있음을 고려한 것이고, 그 동안의 냉난방부하는 저장탱크(4)에 축열 혹은 축냉되어있는 물을 이용하는 것이다.The hot water hot water mode and the heating and cooling mode may be automatically switched by the temperature set values of the respective tanks 4 and 5, and under the same operating conditions, the temperature set value of the hot water hot water tank 5 is given priority to the heat pump. (1) allows priority operation in the hot water supply mode. This is to consider that the user's priority request is in the hot water hot water supply when the heating and cooling hot water load is applied at the same time, and the heating and cooling load during that time is to use the heat stored or stored in the storage tank (4).
도 2는 도 1에 도시된 시스템의 제어상태를 도시한 플로우 챠트로서, 사용자가 온수급탕탱크(5)와 냉온수저장탱크(4)의 온도를 임의로 설정하여 놓으면(S1), 제어기(12)에서 온수급탕탱크(4)의 온도를 상기 단계(S1)에서 설정한 온도와 비교를 하게 되며(S2), 이 단계(S2)에서 온수급탕탱크(5)의 온도가 설정치보다 낮으면 3방전자밸브(V3)가 온수급탕탱크(5)쪽으로 열리도록 절환됨과 동시에 급탕전자밸브 (V2)는 개방되고 냉난방전자밸브(V1)는 폐쇄된다(S3).FIG. 2 is a flow chart showing a control state of the system shown in FIG. 1, when a user arbitrarily sets the temperature of the hot water hot water tank 5 and the cold / hot water storage tank 4 (S1), in the controller 12. The temperature of the hot water hot water tank 4 is compared with the temperature set in the step S1 (S2), and in this step S2, when the temperature of the hot water hot water tank 5 is lower than the set value, the three-discharge valve While V3 is switched to open toward the hot water hot water tank 5, the hot water solenoid valve V2 is opened and the heating and heating solenoid valve V1 is closed (S3).
상기 단계(S3)에 의해 온수급탕모드로 전자밸브(V1,V2,V3)가 모두 절환된 상태에서 히트펌프(1)는 온수급탕모드로 동작하게 되며(S4), 온수급탕탱크(5)의 물을기 설정된 온도가 될 때까지 가열시킴으로써 온수공급을 가능하게 해준다.In the state in which the solenoid valves V1, V2, and V3 are all switched to the hot water supply mode by the step S3, the heat pump 1 operates in the hot water supply mode (S4). Heating the water to a preset temperature allows hot water supply.
한편, 상기 단계(S2)에서 온수급탕탱크(5)의 온도가 설정치 이상인 경우 즉, 온수공급이 충분히 가능한 상태라고 판단되면, 냉온수저장탱크(4)의 온도를 기 설정된 온도와 비교하게 되는데(S5), 이때 하절기 냉방시 냉온수저장탱크(4)의 온도가 설정치보다 높거나, 동절기 난방시 냉온수저장탱크(4)의 온도가 설정치보다 낮을 경우에는 3방전자밸브(V3)가 냉온수저장탱크(4)쪽으로 개방됨과 동시에 냉난방전자밸브(V1)는 개방되고 급탕전자밸브(V2)는 폐쇄된다(S6).On the other hand, if the temperature of the hot water hot water tank (5) in the step (S2) is more than the set value, that is, it is determined that the hot water supply is sufficiently possible, the temperature of the cold and hot water storage tank (4) is compared with the preset temperature (S5) In this case, when the temperature of the cold / hot water storage tank (4) is higher than the set value during the summer cooling or the temperature of the cold / hot water storage tank (4) is lower than the setting value during the winter heating, the three-discharge valve (V3) is a cold / hot water storage tank (4). At the same time, the heating / heating solenoid valve V1 is opened and the hot water supply solenoid valve V2 is closed (S6).
상기 단계(S6)에 의해 냉난방모드로 전자밸브(V1,V2,V3)가 모두 절환된 상태에서 히트펌프(1)는 냉난방모드로 동작하게 되며(S7), 냉온수저장탱크(4)의 물이 설정된 온도가 될 때까지 가열 또는 냉각시킴으로써 실내의 냉난방을 가능하게 해주며, 냉온수저장탱크(4)의 온도가 설정온도에 이루게 되면 히트펌프(1)는 정지하고, 순환펌프(7)는 정지하며, 냉난방 및 급탕 전자밸브(V1,V2)는 폐쇄된다(S8).In the state in which the solenoid valves V1, V2, and V3 are all switched to the cooling and heating mode by the step S6, the heat pump 1 operates in the cooling and heating mode (S7), and the water of the cold / hot water storage tank 4 By heating or cooling until the set temperature is achieved to enable the cooling and heating of the room. When the temperature of the cold / hot water storage tank 4 reaches the set temperature, the heat pump 1 stops and the circulation pump 7 stops. , The heating / cooling and hot water solenoid valves V1 and V2 are closed (S8).
상기 단계(S8)의 상태에서 온수급탕탱크(5)의 온도를 기 설정된 온도와 비교하는 단계(S2)로 회귀하여 상기한 과정을 반복하게 된다.In the state of the step (S8) to return to the step (S2) of comparing the temperature of the hot water hot water tank (5) with a predetermined temperature to repeat the above process.
도 3은 본 발명의 다른 실시예를 도시한 것으로, 본 실시예에서는 상기 제1실시예에서 히트펌프(1)의 출수라인(3)에 설치된 탱크순환펌프(7)와 냉온수저장탱크(4) 및 온수급탕탱크(5)사이에 설치되는 3방전자밸브(V3) 대신 냉난방전자밸브 (V4)와 급탕전자밸브(V5)를 설치한 것이며, 이외에는 상기 첫번째 실시예의 그것과 동일하다.3 shows another embodiment of the present invention. In this embodiment, the tank circulation pump 7 and the cold / hot water storage tank 4 installed in the water outlet line 3 of the heat pump 1 in the first embodiment. And a heating / heating solenoid valve V4 and a hot water supply solenoid valve V5 instead of the three-discharge solenoid valve V3 provided between the hot water hot water supply tanks 5, except that the same as that of the first embodiment.
도 3에 도시된 실시예의 시스템에서의 제어 흐름은 도 4에 도시된 바와 같으며, 단계(S3)에서 2개의 급탕전자밸브(V2,V5)는 열리고 2개의 냉난방전자밸브(V1, V4)는 닫히며, 단계(S6)에서 2개의 급탕전자밸브(V2,V5)는 닫히고 2개의 냉난방전자밸브(V1,V4)는 열리게 되는 점에만 차이가 있을 뿐 전체적으로는 첫번째 실시예와 동일하다.The control flow in the system of the embodiment shown in FIG. 3 is as shown in FIG. 4, in step S3 two hot water solenoid valves V2 and V5 are opened and the two heating and heating solenoid valves V1 and V4 are In the step S6, the two hot water solenoid valves V2 and V5 are closed and the two air heating and solenoid valves V1 and V4 are opened, except that they are the same as the first embodiment as a whole.
이상 설명한 바와 같이 본 발명은 하나의 히트펌프에 의해 냉난방이 가능함과 동시에 온수급탕이 가능하고, 특히 냉온수저장탱크와 온수급탕탱크가 단열처리가 잘된 축열탱크로 이루어져 있어 난방가동초기 과부하 대응성이 뛰어나므로 냉난방 부하에 비해 상대적으로 작은 온수급탕부하를 갖는 사무실이나, 가정, 공장, 연구소 및 상가 등에서 냉난방을 위한 초기투자설비를 절감할 수 있는 유용한 효과를 갖는다.As described above, the present invention is capable of cooling and heating by a single heat pump, and at the same time, hot water hot water supply is possible. In particular, the cold / hot water storage tank and the hot water hot water tank are constituted by heat storage tanks having good thermal insulation, so that the initial heating overload response is excellent. Therefore, it has a useful effect to reduce the initial investment equipment for heating and cooling in offices, homes, factories, research institutes and shopping malls that have a relatively small hot water supply load compared to the heating and cooling load.
