본 발명은 히트펌프식 냉,난방장치에 관한 것으로, 히트펌프의 응축기와 증 발기를 비례제어방식 또는 PID방식에 의한 인버터 제어를 통해 순환사이클의 냉매 압력과 온도를 계절과 기온변화의 구애없이 최적화하여 열효율을 극대화하는 한편, 히트펌프의 일측에 보조증발기를 부설하여 냉방 사이클을 형성함으로써 난방에 대한 열원공급 및 냉수,냉방에 대한 열원을 동시에 공급할 수 있도록 형성한 히트펌프식 냉,난방장치에 관한 것이다.The present invention relates to a heat pump type cooling and heating device, and optimizes the refrigerant pressure and temperature of a circulating cycle regardless of season and temperature change by controlling a condenser and an evaporator of a heat pump using a proportional control method or a PID method. Heat pump type cooling and heating system is designed to maximize the thermal efficiency and to provide a cooling cycle by installing an auxiliary evaporator on one side of the heat pump to simultaneously supply heat source for heating and heat source for cold water and cooling. will be.

일반적으로 히트펌프는 사이클을 이용하여 외부의 대기나 지하수, 지열 등으로부터 열원을 흡입하도록 팬을 사용하여 흡입하고, 흡입된 열원을 냉매가 흐르는 관로 사이로 통과시켜 열을 수집함으로써 학교, 병원, 호텔 등과 같은 대형 또는 공공건물 등의 대용량 온수를 효율적으로 제공하게 된다.In general, the heat pump uses a fan to suck heat sources from the outside atmosphere, groundwater, and geothermal heat using a cycle, and collects heat by passing the sucked heat sources through a pipeline through which refrigerant flows, and so on. Efficiently provide large-scale hot water, such as large or public buildings.

이러한 히트펌프 사이클은 압축기, 열교환기(이는 냉방일 경우 응축기, 난방일 경우 증발기로 사용됨), 팽창밸브, 실내기를 기본구성으로 한다.This heat pump cycle is based on a compressor, a heat exchanger (which is used as a condenser for cooling, an evaporator for heating), an expansion valve, and an indoor unit.

상기 히트펌프의 사용이 난방일 경우, 압축기에서 압축된 고온, 고압의 냉매 는 응축기에서 응축되고(물을 데우는 등의 일을 한다), 그 응축열을 이용하여 온수를 생성하는 한편, 상기 응축기에서 응축된 저온, 저압의 냉매는 다시 팽창밸브를 통해 증발기로 유입된 후 외기열을 흡수하고 다시 압축기로 유입됨으로써 히트펌프의 사이클은 반복된다.When the use of the heat pump is heating, the high-temperature, high-pressure refrigerant compressed in the compressor is condensed in the condenser (heating water, etc.), using the heat of condensation to generate hot water, while condensing in the condenser The low-temperature, low-pressure refrigerant is introduced into the evaporator through the expansion valve, and then absorbs the outside air and enters the compressor again, so that the cycle of the heat pump is repeated.

상술한 바와 같이, 일반적으로 냉,난방 시스템은 압축기, 열교환기, 팽창밸브 및 실내기가 냉매순환 도관으로 연결되는 한편, 상기 도관 일측에 4방밸브를 형성하여 압축기로부터 공급된 냉매의 흐름을 선택적으로 절환함으로써 이루어진다.As described above, a cooling and heating system generally includes a compressor, a heat exchanger, an expansion valve, and an indoor unit connected to a refrigerant circulation conduit, while forming a four-way valve on one side of the conduit to selectively flow the refrigerant supplied from the compressor. By switching.

다시말해, 냉방시에는 증발기, 난방시에는 응축기를 향해 사이클을 순환시킴 으로써 상술한 냉,난방이 이루어지게 되다.In other words, the cooling and heating described above are achieved by circulating a cycle toward the evaporator during cooling and the condenser when heating.

이와 같은 4방밸브 방식은 냉방이나 난방 중 어느 한 실내기만을 선택해서 사용할 수 있는 바, 이는 동시에 냉방과 난방 시스템을 가동할 수 없다는 문제가 발생된다.The four-way valve method can be used to select only one of the indoor unit of the cooling or heating, which causes a problem that can not operate the cooling and heating system at the same time.

또한, 히트펌프로 공급되는 물의 온도가 너무 차면 이를 가열하기 위한 히트펌프의 초기 작동에 과부하가 발생되는 등 시동에 내구성이 약해져 잔고장의 원인이 되며, 이는 작동오류의 문제를 야기시켜 열효율이 저하되는 문제가 발생되고 있다.In addition, if the temperature of the water supplied to the heat pump is too cold, the initial operation of the heat pump for heating it is overloaded, such as the durability of the start-up weakened due to the failure, which causes a problem of operation error is reduced thermal efficiency Problems are occurring.

이는 종래의 냉,난방장치가 온수의 온도만을 감지하여 작동되므로 외부대기의 기온변화와 히트펌프의 냉매압력과 온도에 따른 상호 제어가 신속하게 이루어지지 못함으로써 결국 히트펌프가 오작동하는 문제가 발생되고 있다.This is because the conventional cooling and heating device operates only by detecting the temperature of hot water, and thus the heat pump malfunctions because the temperature control of the external air and the mutual control of the refrigerant pressure and temperature of the heat pump are not performed quickly. have.

본 발명은 상술한 문제점을 해결하고자 하는 것으로, 히트펌프의 응축기와 증발기를 비례제어방식 또는 PID방식에 의한 인버터 제어를 통해 순환사이클의 냉매 압력과 온도를 계절과 기온변화의 구애없이 최적화하여 열효율을 극대화하는 한편, 히트펌프의 일측에 보조증발기를 부설하여 냉방 사이클을 형성함으로써 난방에 대한 열원공급 및 냉수,냉방에 대한 열원을 동시에 공급할 수 있도록 형성한 히트펌프식 냉,난방장치를 제공함에 그 목적이 있다.The present invention is to solve the above problems, through the control of the condenser and evaporator of the heat pump by proportional control method or PID method to optimize the refrigerant pressure and temperature of the circulation cycle regardless of season and temperature changes to improve thermal efficiency In addition, by providing an auxiliary evaporator on one side of the heat pump to form a cooling cycle, to provide a heat pump cooling and heating device formed to supply a heat source for heating and a heat source for cold water and cooling at the same time. There is this.

다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.The following describes the present invention in more detail with reference to the accompanying drawings.

도 1에 도시된 바와 같이, 본 발명의 핵심은 온수공급을 위한 히트펌프식 회로에 냉방용 보조증발기(320)를 일측에 병설 또는 부설하여, 4방밸브를 구성한 히트펌프 시스템과는 달리 냉, 난방이 동시에 가동될 수 있도록 형성되는 것이 특징이다.As shown in Figure 1, the core of the present invention is installed or installed on the side of the cooling auxiliary evaporator 320 in the heat pump type circuit for hot water supply, unlike the heat pump system consisting of a four-way valve, It is characterized by being formed so that the heating can be operated at the same time.

이를 위해, 본 발명은 온수공급장치의 기본 회로인 저장탱크(100), 보조탱크(200), 히트펌프(300), 온수탱크(400) 및 이들을 연결한 도관(500a~500d)에 있어서, 상기 히트펌프(300) 일측에 냉방용 보조증발기(320)를 병설하여 인버터(900)에 의해 증발량을 상호 제어함으로써 그 목적이 실현된다.To this end, the present invention in the storage tank 100, the auxiliary tank 200, the heat pump 300, the hot water tank 400 and the conduits (500a ~ 500d) connecting them, the basic circuit of the hot water supply device, the The purpose of this is achieved by providing a cooling auxiliary evaporator 320 on one side of the heat pump 300 and mutually controlling the evaporation amount by the inverter 900.

이를 보다 상세히 살펴보면, 먼저 저장탱크(100)가 일측에 형성되는 바, 이는 외부로부터 공급된 상온수(찬물)를 저장하게 된다.Looking at this in more detail, first the storage tank 100 is formed on one side, which stores the room temperature water (cold water) supplied from the outside.

이때, 상기 보조탱크(200)는 저장탱크(100)로부터 상온수를 공급받아 수용하는 한편, 일측 출수구측 도관(500b)을 통해 히트펌프(300)로 상온수를 공급하게 된다.At this time, the auxiliary tank 200 receives and receives the room temperature water from the storage tank 100, while supplying the room temperature water to the heat pump 300 through the one side outlet port conduit (500b).

이러한 보조탱크(200)는 히트펌프(300)로 직수되는 물의 온도편차를 1차로 체크하여 상기 히트펌프(300)가 과부하에 의해 장치오류를 범하지 않도록 물의 온도를 일정부분 예열하거나 혼합시키도록 하는 중간 거점 역활을 하게 된다.The auxiliary tank 200 checks the temperature deviation of the water directly directed to the heat pump 300 to preheat or mix the temperature of the water to a certain degree so that the heat pump 300 does not commit a device error due to an overload. It will serve as an intermediate base.

이러한 보조탱크(200)의 출수구측 도관(500b)에는 체크밸브(210)가 부설되어 최초 공급되는 물의 온도 체크는 물론, 가열된 온수의 순환시 상승되는 온도를 체크하여 증발기의 팬 회전량과 급수펌프(600)의 회전속도에 연동되어 비례제어 되도록 설정된다.A check valve 210 is installed in the outlet side conduit 500b of the auxiliary tank 200 to check the temperature of the water initially supplied, as well as to check the temperature rising during the circulation of the heated hot water, and to supply the fan rotation amount and the water supply of the evaporator. It is set to be proportionally controlled in conjunction with the rotational speed of the pump 600.
