본 발명은 히트펌프식 냉난방 시스템에 관한 것으로서, 더욱 상세하게는 동절기와 하절기 상관없이 항상 고온 냉매와 열교환된 급탕수를 공급할 수 있으며 급탕수의 생산시 열교환기를 열원으로 하지 않고 압축기에서 토출되는 고온 냉매를 열원으로 하여 기기의 안정을 도모하고, 급탕수 공급과 동시에 실내를 냉난방할 수 있는 바닥 난방과 동시 급탕이 가능한 히트펌프식 냉난방 시스템에 관한 것이다.The present invention relates to a heat pump type heating and cooling system, and more particularly, hot water can be always supplied to the hot water heat exchanged with the hot refrigerant regardless of winter and summer, and hot water discharged from the compressor without the heat exchanger as a heat source during the production of hot water. The present invention relates to a heat pump air-conditioning system capable of stabilizing equipment by supplying a heat source, and simultaneously supplying hot water and floor heating and hot water supply.

주지된 바와 같이 히트펌프식 냉난방 시스템은, 냉매의 선택적 양방향 흐름을 통해 난방계절 동안은 고압측(응축기)에서의 방출열을 활용하여 난방 및 온수를 제공하고 냉방계절 동안은 저압측(증발기)에서의 주변열 흡수를 활용하여 냉기를 제공할 수 있도록 된 시스템을 말한다.As is well known, the heat pump type heating and cooling system utilizes the heat emitted from the high pressure side (condenser) during the heating season through the selective bi-directional flow of the refrigerant to provide heating and hot water, and the low pressure side (evaporator) during the cooling season. It is a system that can provide cold air by utilizing the absorption of ambient heat.

이와 같은 히트펌프식 냉난방 시스템은 그 적용환경에 따라 다양한 구조로 응용되어 사용되고 있으나 기본적으로 압축기, 응축기, 팽창밸브 및 증발기 등 냉동 사이클을 이루는 4개의 기본 요소기기로 이루어져 있으며, 이러한 냉동 사이클의 구성에 냉매의 유동방향을 전환하여 냉방 또는 난방기기로의 선택적 활용이 가능토록 사방밸브를 더 포함하고 있다.The heat pump type air-conditioning system is used in various structures according to its application environment, but it basically consists of four basic elements that form a refrigeration cycle such as a compressor, a condenser, an expansion valve, and an evaporator. It further includes a four-way valve to selectively change the flow direction of the refrigerant to be used as cooling or heating equipment.

즉, 도 1에 도시된 바와 같이 종래의 일반적인 히트펌프식 냉난방 시스템은, 압축기(1), 실내기(2), 팽창밸브(3), 실외기(4) 등의 기본구성요소를 포함하여 이루어진 통상의 냉방 시스템과, 이러한 냉방 시스템에 있어 상기 팽창밸브(3)와 실외기(4) 사이 그리고 압축기(1)와 실내기(2) 사이에 선택적으로 포트를 전환하여 냉매의 순환방향을 전환시키기 위해 마련되는 사방밸브(5a)를 포함하여 이루어진다. 도면 중 미설명부호 5b는 실내기(2)와 실외기(4) 사이에 설치되어 냉매의 역류를 방지하는 역류방지밸브(5b)이고, 도면 부호 9는 어큐뮬레이터이다.That is, as shown in FIG. 1, a conventional heat pump type heating and cooling system according to the related art includes a basic component including a compressor 1, an indoor unit 2, an expansion valve 3, an outdoor unit 4, and the like. Cooling system and in this cooling system are provided for changing the circulation direction of the refrigerant by selectively switching ports between the expansion valve (3) and the outdoor unit (4) and between the compressor (1) and the indoor unit (2) It comprises a valve (5a). In the figure, reference numeral 5b denotes a non-return valve 5b installed between the indoor unit 2 and the outdoor unit 4 to prevent the backflow of the refrigerant, and reference numeral 9 denotes an accumulator.

이와 같이 구성된 히트펌프식 냉난방 시스템은, 압축-응축-팽창-증발 등의 일련의 냉방 사이클을 통해 통상의 난방기기로 활용되며, 사방밸브(5a)의 동작에 따른 냉매의 역순환에 따라 냉방기기로 활용되기도 한다.The heat pump type air-conditioning system configured as described above is utilized as a normal heating device through a series of cooling cycles such as compression, condensation, expansion, and evaporation, and is cooled by the reverse circulation of the refrigerant according to the operation of the four-way valve 5a. Also used as.

상기와 같은 히트펌프식 냉반방 시스템을 좀 더 구체적으로 살펴보면, 냉방 시 냉매가 실내기(2)내에서 증발하면서 주변의 열원을 흡수하는 흡열과정을 거친 후 실외기(4)에서 방열될 때, 상기 실내기(2)측의 흡열량을 이용하면 냉방기로 활용될 수 있는 것이고, 이와는 달리 사방밸브(5a)의 조작에 의해 냉매의 흐름방향이 냉방시와는 역으로 전환되는 경우에는 상기 냉방시의 실내기(2)가 응축기로 활용되고 실외기(4)가 증발기로 활용되기 때문에 실내기(2)에의 방출열량을 이용하면 난방기기로 활용할 수 있게 되는 것이다. 즉, 냉동시에는 저압측 증발기에서의 흡열량을 이용하고, 난방시에는 고압측 응축기에서의 방출열량을 이용하는 것이다.Looking at the heat pump type cold half system as described above in more detail, when the refrigerant is radiated in the outdoor unit (4) after undergoing an endothermic process of absorbing the surrounding heat source while evaporating in the indoor unit (2), the indoor unit If the endothermic amount on the (2) side is used, it can be utilized as a cooler. On the contrary, when the flow direction of the coolant is reversed from the cooling time by the operation of the four-way valve 5a, the indoor unit at the time of cooling ( Since 2) is used as a condenser and the outdoor unit 4 is used as an evaporator, the amount of heat emitted to the indoor unit 2 can be used as a heating device. In other words, the endothermic amount of the low pressure side evaporator is used for freezing, and the amount of heat released from the high pressure side condenser is used for heating.

그러나 상기와 같은 구성과 작동원리를 갖는 종래의 일반적인 히트펌프식 냉난방 시스템에는 별도의 온수공급수단이 마련되어 있지 않기 때문에, 냉방기로 활용되는 하절기나 환절기에 온수를 제공받기 위해서는 별도로 보일러를 가동시켜야 하므로 경제적 측면에서 효율적이지 못하다는 문제가 있다.However, in the conventional general heat pump type heating and cooling system having the above-described configuration and operation principle, since a separate hot water supply means is not provided, a boiler must be operated separately in order to receive hot water in a summer or a season used as a cooler. There is a problem that is not efficient in terms of.

더욱이, 히트펌프식 냉난방 시스템이 냉방기기로 활용될 경우에 증발기를 통해 흡수된 열량을 충분히 재사용할 수 있음에도 불구하고 응축기를 통해 그대로 방열되어 폐기되므로 에너지의 효율적 이용이라는 관점에서 보면 매우 비경제적인 것이다.Moreover, even when the heat pump type air-conditioning system is utilized as a cooling device, even though the heat absorbed through the evaporator can be sufficiently reused, it is uneconomical in terms of efficient use of energy since it is radiated and disposed of as it is through the condenser.

이러한 문제점을 해결하기 위하여 히트펌프식 냉난방 시스템이 냉방기기로 활용되는 경우의 실내기와 실외기 사이에 관로를 흐르는 냉매의 열원을 이용하여 물의 온도를 상승시킬 수 있는 온수공급장치를 마련하여, 냉방시스템으로 활용되는 하절기 또는 환절기에도 온수를 제공할 수 있는 기술이 제안된 바 있다.In order to solve this problem, by providing a hot water supply device that can raise the temperature of the water by using a heat source of the refrigerant flowing through the pipe between the indoor unit and the outdoor unit when the heat pump type air-conditioning system is used as a cooling device, It has been proposed a technology that can provide hot water even in the summer or the season used.

그러나, 종래 온수공급장치는 실내기와 실외기를 통과하는 냉매의 열을 열원으로 온수를 생산하기 때문에 실내의 난방 효율이 떨어지고 이를 해결하기 위하여 압축기의 운전율을 높이는 등의 문제점이 있다.However, in the conventional hot water supply device, since hot water is produced by using heat of a refrigerant passing through the indoor unit and the outdoor unit as a heat source, the heating efficiency of the indoor unit decreases and the operation rate of the compressor is increased to solve this problem.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 동절기와 하절기 상관없이 기기를 안정적으로 가동하면서 급탕수를 생산할 수 있는 바닥 난방과 동시 급탕이 가능한 히트펌프식 냉난방 시스템을 제공하는데 그 목적이 있다. An object of the present invention is to provide a heat pump type heating and cooling system capable of simultaneously heating water with floor heating capable of producing hot water while stably operating the device regardless of winter and summer.

그리고, 본 발명의 다른 목적은 실내를 난방하기 위한 실내측 열교환기의 냉매에 온도 변화를 주지 않고 계절에 상관없이 고온의 냉매를 공급하는 압축기측에서 열원을 확보하여 기기를 안정적으로 가동하면서 급탕수를 공급하고, 급탕수의 생산과 동시에 실내를 냉난방하려는데 있다.In addition, another object of the present invention is to secure a heat source on the compressor side for supplying a high temperature refrigerant regardless of the season without changing the temperature of the refrigerant of the indoor side heat exchanger for heating the room while operating the device stably It is to supply air, and to heat the room simultaneously with the production of hot water.

전술한 바와 같은 목적을 달성하기 위한 본 발명에 의한 바닥 난방과 동시 급탕이 가능한 히트펌프식 냉난방 시스템은, 압축기의 토출측과 사방밸브 사이에 직렬로 연결되어 상기 압축기에 의해 토출되는 고온고압의 냉매가 흐르는 급탕용 열교환기와; 원수를 급탕수 탱크를 거쳐 상기 급탕용 열교환기에 공급함으로써 냉매와 열교환시켜 급탕수를 급탕수 탱크에 공급하는 급탕수 공급관과; 바닥에 매설된 난방 배관과 실내기에 연결되어 상기 실내기가 응축기로 사용될 때 난방 배관에서 토출된 난방수를 상기 실내기에 연속 순환시켜 상기 난방 배관에 공급하는 난방수 순환관과; 냉방을 위한 팬코일 유니트와 상기 실내기에 연결되어 상기 실내기가 증발기로 사용될 때 상기 팬코일 유니트에서 토출된 냉방수를 상기 실내기에 연속 순환시켜 상기 팬코일 유니트에 공급하는 냉방수 순환관을 포함하는 것을 특징으로 한다.In the heat pump type heating and cooling system capable of simultaneous hot water supply and floor heating according to the present invention for achieving the above object, the high temperature and high pressure refrigerant discharged by the compressor is connected in series between the discharge side of the compressor and the four-way valve.

It features.

본 발명에 따른 바닥 난방과 동시 급탕이 가능한 히트펌프식 냉난방 시스템에 의하면, 압축기에서 토출된 고온의 냉매로부터 고온의 열원을 확보하여 이 열원을 통하여 급탕수를 생산하며, 압축기에서 토출된 냉매는 냉방과 난방시 모두 고온을 유지하므로 열교환기에 부담을 주지 않고 동절기와 하절기 모두 급탕수를 공급할 수 있다. 결과적으로 고온의 냉매를 토출하는 압축기측에서 고온의 열원을 확보하여 열교환기의 냉매로부터 열원을 빼앗지 않기 때문에 열교환기를 통과하는 고온 냉매의 열을 손실없이 실내에 공급할 수 있으므로 난방효율을 높일 수 있다.According to the heat pump type heating and cooling system capable of simultaneously heating the floor according to the present invention, the hot water is secured from the high temperature refrigerant discharged from the compressor to produce hot water supply through the heat source, and the refrigerant discharged from the compressor is cooled. Hot and cold water can be supplied in both winter and summer without burdening the heat exchanger. As a result, since a high temperature heat source is secured on the compressor side that discharges the high temperature refrigerant, and the heat source is not removed from the refrigerant of the heat exchanger, heat of the high temperature refrigerant passing through the heat exchanger can be supplied to the room without loss, thereby improving heating efficiency.

그리고, 급탕수를 항상 제공하면서 실내를 냉방 및 난방하므로 냉난방 시스템의 효용성을 높일 수 있고 신뢰성을 향상할 수 있다.In addition, since the room is cooled and heated while always providing hot water, the utility of the air conditioning system can be improved and reliability can be improved.

The refrigerant compressed by the compressor 1 at high temperature and high pressure passes through the hot water heat exchanger 10 before being supplied to the indoor unit 2 or the outdoor unit 4 via the four-way valve 5a.

한편, 원수는 급탕수 탱크(40)에 유입되고, 급탕수 탱크(40)내의 원수는 원수 공급관(20)을 통해 급탕용 열교환기(10)에 투입된다.On the other hand, the raw water is introduced into the hot water supply tank 40, the raw water in the hot water supply tank 40 is introduced into the hot water heat exchanger 10 through the raw water supply pipe (20).

When the heating mode is selected, as shown in FIG. 2, the cooling water supply pipe 60 is closed and only the heating water supply pipe 50 is opened by the valves V1 and V2.

난방용 펌프(54)가 가동하면 난방수 회수관(51)을 통해 난방 배관(53) 내의 난방수가 실내기(2)에 투입되어 실내기(2) 내의 고온의 냉매와 열교환함으로써 온도가 상승한다.When the heating pump 54 operates, the heating water in the heating pipe 53 is introduced into the indoor unit 2 through the heating water recovery pipe 51, and the temperature is increased by heat exchange with the high temperature refrigerant in the indoor unit 2.

이 난방수는 난방수 공급관(52)을 통해 난방 배관(53)에 공급되어 난방 배관(53)을 순환하면서 실내 바닥을 난방한다.The heating water is supplied to the heating pipe 53 through the heating water supply pipe 52 to circulate the heating pipe 53 to heat the indoor floor.

3. 냉방3. Cooling

냉매가 압축기(1) - 사방변(5a) - 실외기(4) - 팽창변(3) - 실내기(2)를 순환하며, 실내기(2)는 저온의 냉매가 통과하여 증발기의 기능을 수행하고 실외기(4)는 응축기의 기능을 수행한다. 냉방모드를 선택하면, 도 3에서 보이는 것처럼, 밸브(V1,V2)에 의해 난방수 공급관(50)은 폐쇄되고 냉방수 공급관(60)만 개방된다.

When the cooling mode is selected, as shown in FIG. 3, the heating water supply pipe 50 is closed by the valves V1 and V2 and only the cooling water supply pipe 60 is opened.

냉방용 펌프(64)가 가동하면 냉방수 회수관(61)을 통해 팬코일 유니트(63)를 순환한 냉방수가 실내기(2)에 투입되어 실내기(2) 내의 저온의 냉매와 열교환함으로써 온도가 낮아진다.When the cooling pump 64 is operated, the cooling water circulated through the fan coil unit 63 through the cooling water recovery pipe 61 is introduced into the indoor unit 2, and the temperature is lowered by heat exchange with the low temperature refrigerant in the indoor unit 2. .

이 냉방수는 냉방수 공급관(62)을 통해 팬코일 유니트(63)에 공급되어 팬코 일 유니트(63)를 순환하면서 공기와 열교환됨으로써 이 공기에 의해 실내가 냉방되도록 한다.The cooling water is supplied to the fan coil unit 63 through the cooling water supply pipe 62 to heat the air while circulating the fan coil unit 63 so that the room is cooled by the air.
