본 발명은 산업용 및 주택, 아파트 등에 적용가능한 히트펌프용 동시 난방 온수시스템에 관한 것으로서, 필요 시 난방기 및 온수탱크를 동시에 또는 선택적으로 사용하여 과다한 운영비를 절감할 수 있는 히트펌프용 동시 난방 온수시스템이다.The present invention relates to a simultaneous heating hot water system for a heat pump applicable to industrial, home, apartment, etc., a simultaneous heating hot water system for a heat pump that can reduce the excessive operating cost by using the heater and hot water tank simultaneously or selectively when necessary. .

일반적으로 히트 펌프 시스템은 압축기, 열교환기, 실내 열교환기, 팽창밸브, 실외 열교환기 및 상기 열교환기를 도관으로 순서대로 연결하고, 상기 열교환기와 압축기를 흡입 도관으로 연결하여서, 가열 운전시에는 열교환기를 고온/고압의 냉매 증기가 실내 열교환기 측으로 흐르도록 조작하여 그 응축열을 유체와 열교환 시킴으로써 온수를 생성하거나 실내공기를 가열하여서 난방 또는 건조기능을 수행하게 하는 것이다.In general, a heat pump system connects a compressor, a heat exchanger, an indoor heat exchanger, an expansion valve, an outdoor heat exchanger, and the heat exchanger in order with a conduit, and connects the heat exchanger and the compressor with a suction conduit so that the heat exchanger is heated at a high temperature. The high-pressure refrigerant vapor flows to the indoor heat exchanger to exchange heat with the condensation fluid to generate hot water or to heat the indoor air to perform heating or drying functions.

그리고, 실내 열교환기에서 응축된 고온/고압의 냉매 액을 팽창밸브에서 팽창시킨 후 증발기로 작용하는 실외 열교환기에서 외기를 열원으로 하여 증발시켜 저온/저압의 냉매증기가 되게 한 후 압축기에 흡입되는 사이클을 반복시키게 되는 것이다.Then, the high-temperature / high pressure refrigerant liquid condensed in the indoor heat exchanger is expanded by the expansion valve, and the outdoor heat exchanger acting as an evaporator evaporates the outdoor air as a heat source to make the low-temperature / low pressure refrigerant vapor and is sucked into the compressor. Will repeat the cycle.

또한, 냉방운전시에는 열교환기를 고온/고압의 냉매가 실외 열교환기 측으로 흐르도록 조작하여 압축기에서 압축된 고온/고압의 냉매증기를 응축기로 작용하는 실외 열교환기에서 응축시키고, 실외 열교환기에서 응축된 고온/고압의 냉매 액을 팽창밸브에서 팽창시킨 후 증발기로 작용하는 실내 열교환기에서 냉매 액을 증발시켜 그 증발열을 유체와 열교환 시킴으로써 냉수를 생성하거나 실내 공기를 냉각시킴으로써 실내 냉방을 하고, 실내 열교환기에서 증발된 저온/저압의 냉매증기는 압축기에 흡입되는 사이클을 반복하는 것이다.Also, during the cooling operation, the heat exchanger is operated so that the high temperature / high pressure refrigerant flows to the outdoor heat exchanger side, thereby condensing the high temperature / high pressure refrigerant vapor compressed by the compressor in the outdoor heat exchanger acting as a condenser, and condensing in the outdoor heat exchanger. After expanding the high-temperature / high-pressure refrigerant liquid in the expansion valve, the refrigerant liquid is evaporated in an indoor heat exchanger that acts as an evaporator to heat the evaporation heat with the fluid to generate cold water or to cool the indoor air. The refrigerant vapor of low temperature / low pressure evaporated at is repeated a cycle of being sucked into the compressor.

이러한, 냉난방 히트 펌프는 냉/난방의 사이클이 순환하면서 필요한 열기와 냉기를 얻어 필요한 장소에 공급하는 것이며, 이러한 열기와 냉기를 얻기 위해서는 순환 사이클을 역으로 순환시켜 사용하는 보편적인 냉/난방 히트 펌프의 기술이다.Such a heating and cooling heat pump is to supply the necessary heat and cold air to the required place as the cooling / heating cycle is circulated, and to obtain such hot and cold air, a general cooling / heating heat pump that uses the circulation cycle in reverse.

그러나, 이러한 순환식 히트 펌프의 가동에 있어서, 냉방을 필요로 하는 장소에 냉기를 공급하면서 이와 동시에 난방을 필요로 하는 장소에 열기를 공급하기 위해서는 별도의 시설과 제어부를 가져야만 가능하였다.However, in the operation of such a circulating heat pump, in order to supply cold air to a place requiring cooling while simultaneously supplying heat to a place requiring heating, it was possible to have a separate facility and a control unit.

본 발명은 고온/고압의 압축 가스를 필요시 선택적으로 난방기 또는 온수탱크에 공급하거나 난방기와 온수탱크를 동시에 공급 적용할 수 있는 콤팩트한 구조의 히트펌프용 동시 난방 온수시스템을 제공하고자 하는 것이다.The present invention is to provide a simultaneous heating hot water system for a heat pump of a compact structure capable of supplying a high-temperature / high pressure compressed gas selectively to the heater or hot water tank, or simultaneously supply and apply the heater and hot water tank.
