도 2 및 도 3에 도시된 바와 같이, 본 발명에 따른 건물의 냉방장치(200)를 이용한 쇼케이스(100)는, 냉각사이클, 송풍팬(150), 선반(160a,160b,160c), 메인 열교환기(300)를 포함한다.As shown in Figure 2 and 3, the showcase 100 using the cooling device 200 of the building according to the present invention, the cooling cycle, the blowing fan 150, the shelf (160a, 160b, 160c), the main heat exchange Group 300.

먼저, 냉각사이클은 냉매를 순환시키도록 압축기(110), 응축기(120), 팽창밸브(130), 및 증발기(140)로 이루어진다.First, the cooling cycle consists of a compressor 110, a condenser 120, an expansion valve 130, and an evaporator 140 to circulate the refrigerant.

냉각사이클을 이루는 압축기(110), 응축기(120), 팽창밸브(130), 및 증발기(140)는 이미 공지된 기술이므로 여기서는 그 상세한 설명은 생략한다.Since the compressor 110, the condenser 120, the expansion valve 130, and the evaporator 140 constituting the cooling cycle are well known in the art, detailed description thereof will be omitted herein.

상기 송풍팬(150)은 냉각사이클에서 증발기(140)의 차가운 냉매와 열교환된 공기를 저장물의 저장공간(170)으로 토출시킨다.The blowing fan 150 discharges the air heat-exchanged with the cold refrigerant of the evaporator 140 in the storage cycle 170 in the cooling cycle.

상기 선반(160a,160b,160c)은 저장공간(170)에 구비되어 저장물을 안착시키며, 복수개로 이루어진다. 이러한 선반(160a,160b,160c)은 통상 저장공간(170) 내부에 상하방향으로 복수개가 적층되며, 필요에 따라 좌우방향으로 배열되어도 무방하다.The shelves 160a, 160b, and 160c are provided in the storage space 170 to seat the storage, and are formed in plural. A plurality of shelves 160a, 160b, and 160c are normally stacked in the storage space 170 in the vertical direction, and may be arranged in the left and right directions as necessary.

한편, 메인 열교환기(300)는 건물의 냉방장치(200)를 구성하는 냉각기(210)로부터 차가운 냉매를 유입배관(301)을 통해 유입하여 응축기(120)와 열교환한 후에 이 열교환된 냉매를 유출배관(302)을 통해 냉각기(210)로 유출시킨다.On the other hand, the main heat exchanger 300 flows cold refrigerant from the cooler 210 constituting the air conditioner 200 of the building through the inlet pipe 301 to exchange heat with the condenser 120, and then flows out the heat-exchanged refrigerant. Outflow to the cooler 210 through the pipe 302.

통상 건물의 냉방장치(200)는 냉매를 순환하도록 발생기, 흡수기, 방열기, 팽창밸브, 증발기, 및 냉각기(210)로 이루어진다. 이러한 건물의 냉방장치(200)는 이미 공지된 기술이므로, 여기서는 본 발명과 밀접한 관련이 있는 냉각기(210)만을 도시하였으며, 이 냉방장치(200)의 전체 동작에 대한 설명은 생략한다.In general, the air conditioner 200 of a building includes a generator, an absorber, a radiator, an expansion valve, an evaporator, and a cooler 210 to circulate a refrigerant. Since the cooling device 200 of such a building is a known technology, only the cooler 210 is shown here, which is closely related to the present invention, and a description of the overall operation of the cooling device 200 will be omitted.

이러한 냉방장치(200)의 냉매는 염화칼슘이거나 에틸렌글리콜이며, 이 냉방장치(200)에서 냉각기(210)를 통과하는 냉매는 상기한 쇼케이스(100)의 냉각사이클을 순환하는 냉매의 온도보다 더 낮은 온도를 유지한다.The refrigerant of the cooling device 200 is calcium chloride or ethylene glycol, and the refrigerant passing through the cooler 210 in the cooling device 200 is lower than the temperature of the refrigerant circulating in the cooling cycle of the showcase 100 described above. Keep it.

즉, 본 발명은 쇼케이스(100)의 냉각사이클을 순환하는 냉매보다 상대적으로 낮은 온도의 냉매로 상기 응축기(120)에서 발생된 열을 직접 냉각시키므로, 종래의 송풍팬의 구동에 의해 발생된 공기로 응축기를 냉각시키는 방식보다 응축기의 열교환 효율을 상승시킬 수 있을 뿐만 아니라, 이로 인해 쇼케이스 냉각사이클의 전체 냉각효율을 상승시킬 수가 있다.That is, the present invention directly cools the heat generated in the condenser 120 with a refrigerant having a relatively lower temperature than the refrigerant circulating the cooling cycle of the showcase 100, and thus, the air generated by the driving of a conventional blower fan. Not only can the heat exchange efficiency of the condenser be increased, but also the overall cooling efficiency of the showcase cooling cycle can be increased.

또한 종래의 실외기를 제거하여도 응축기(120)의 방열이 가능하고, 실외기 설치에 따른 비용도 절감시킬 수 있는 장점이 있다.In addition, the heat dissipation of the condenser 120 is possible even if the conventional outdoor unit is removed, and there is an advantage of reducing the cost of installing the outdoor unit.

도 2에서, 메인 열교환기(300)는 응축기(120)와 서로 어느 일면이 마주하는 형상을 가진다.In FIG. 2, the main heat exchanger 300 has a shape in which one surface thereof faces the condenser 120.

하지만, 도 3에 도시된 바와 같이 메인 열교환기(300)와 응축기(120)는 서로 엇갈리게 적층된 형상을 가져도 무방하다.However, as shown in FIG. 3, the main heat exchanger 300 and the condenser 120 may have a shape stacked alternately with each other.

상기 메인 열교환기(300)와 응축기(120)가 서로 엇갈리게 적층된 형상을 가짐과 더불어, 열교환 효율이 증대되도록 메인 열교환기(300)를 이루는 냉매배관(303)과 응축기(120)를 이루는 냉매배관(121)이 서로 교차 배치되는 것이 바람직하다.The main heat exchanger (300) and the condenser (120) have a shape stacked alternately with each other, and the refrigerant pipe forming the refrigerant pipe 303 and the condenser 120 forming the main heat exchanger 300 to increase the heat exchange efficiency. It is preferable that 121 are mutually arrange | positioned.

본 발명에 따른 건물의 냉방장치(200)를 이용한 쇼케이스(100)는, 복수개의 선반(160a,160b,160c)을 직접 냉각시키도록 각 선반(160a,160b,160c)들과 배관으로 연결되는 복수개의 보조 열교환기(310a,310b,310c)를 더 구비한다.Showcase 100 using the cooling device 200 of the building according to the present invention, the plurality of shelves (160a, 160b, 160c) are connected to the plurality of shelves (160a, 160b, 160c) to the pipe directly to the plurality It further comprises two auxiliary heat exchangers (310a, 310b, 310c).

실시예에서, 보조 열교환기(310a,310b,310c)들은 냉각사이클에서 팽창밸브(130)의 유출측으로부터 상기 냉각사이클을 순환하는 냉매 중 일부의 냉매를 유입하여 각 선반(160a,160b,160c)들을 냉각시킨 후에 증발기(140)의 유입측으로 냉매를 다시 유출시킨다.In an embodiment, the auxiliary heat exchangers 310a, 310b, and 310c introduce each of the shelves 160a, 160b, and 160c by introducing some of the refrigerant circulating through the cooling cycle from the outlet side of the expansion valve 130 in the cooling cycle. After cooling them, the refrigerant flows out again to the inlet side of the evaporator 140.

본 발명은 송풍팬(150)에 의한 냉기순환 방식 즉, 간접냉각 방식으로 선반(160a,160b,160c)에 안착된 저장물을 냉각시킬 뿐만 아니라, 보조 열교환기(310a,310b,310c)들에 의해 선반(160a,160b,160c)을 직접 냉각시키기 때문에, 저장물을 냉각시키는 시간이 대폭 단축되고 신선도를 오래 지속시킬 수 있어서 냉각효율을 상승시킬 수 있는 장점이 있다.The present invention not only cools the storage seated on the shelves 160a, 160b, and 160c in a cold air circulation method, that is, indirect cooling by the blower fan 150, but also to the auxiliary heat exchangers 310a, 310b, and 310c. By directly cooling the shelves (160a, 160b, 160c), the time to cool the storage is greatly shortened and the freshness can be maintained for a long time has the advantage of increasing the cooling efficiency.

본 발명에 따른 건물의 냉방장치(200)를 이용한 쇼케이스(100)의 동작은 도 2에 도시된 바와 같이, 먼저 냉각사이클을 구동시킨 후, 이 냉각사이클 중에서 응축기(120)에서 발생된 열은 메인 열교환기(300)가 건물의 냉각기(210)에서 제공되는 차가운 냉매를 공급받아 냉각시키게 된다.As shown in FIG. 2, the operation of the showcase 100 using the air conditioner 200 of the building according to the present invention first drives a cooling cycle, and then heat generated from the condenser 120 is main during the cooling cycle. The heat exchanger 300 is cooled by receiving a cool refrigerant provided from the cooler 210 of the building.

상기한 상태에서, 보조 열교환기(310a,310b,310c)들은 냉각사이클을 순환하는 냉매 중 일부의 냉매를 유입하여 각각의 선반(160a,160b,160c)에 안착된 저장물을 냉각시킨다.In the above state, the auxiliary heat exchangers 310a, 310b, and 310c flow in the refrigerant of some of the refrigerants circulating in the cooling cycle to cool the storage mounted on the respective shelves 160a, 160b, and 160c.

즉, 보조 열교환기(310a,310b,310c)들은 팽창밸브(130)의 유출측으로부터 냉매를 유입하여 각 선반(160a,160b,160c)들을 냉각시킨 후에 증발기(140)의 유입측으로 냉매를 다시 유출시킨다.That is, the auxiliary heat exchangers (310a, 310b, 310c) flows the refrigerant from the outlet side of the expansion valve 130 to cool the respective shelves (160a, 160b, 160c), and then flows out the refrigerant to the inlet side of the evaporator 140 again. Let's do it.

상기와 같은 구성을 가지는 본 발명은 여러개의 쇼케이스에 동시에 적용하여도 무방하다.The present invention having the above configuration may be applied to multiple showcases simultaneously.

상기한 바와 같이 본 발명은, 건물의 냉방장치를 구성하는 냉각기로부터 차가운 냉매를 유입배관을 통해 유입하여 응축기와 열교환한 후에 이 열교환된 냉매를 유출배관을 통해 냉각기로 유출시키는 메인 열교환기를 더 포함하므로서, 종래의 응축기를 냉각시키는 방식보다 응축기의 열교환 효율을 상승시킬 수 있을 뿐만 아니라, 이로 인해 쇼케이스 냉각사이클의 전체 냉각효율을 상승시킬 수가 있는 우수한 효과가 있다.As described above, the present invention further includes a main heat exchanger which introduces cool refrigerant from the cooler constituting the air conditioner of the building through the inlet pipe to exchange heat with the condenser, and then discharges the heat exchanged refrigerant to the cooler through the outlet pipe. In addition, the heat exchange efficiency of the condenser can be increased more than the conventional method of cooling the condenser, and thus, the overall cooling efficiency of the showcase cooling cycle can be increased.

아울러, 본 발명은 복수개의 선반을 직접 냉각시키도록 각 선반들과 배관으로 연결되는 복수개의 보조 열교환기를 더 구비하므로서, 저장물을 냉각시키는 시간이 대폭 단축되고 신선도를 오래 지속시킬 수 있어서 냉각효율을 상승시킬 수 있는 우수한 효과가 있다.In addition, the present invention further includes a plurality of auxiliary heat exchangers connected to the respective shelves and pipes to directly cool the plurality of shelves, thereby significantly reducing the time for cooling the storage and maintaining the freshness for a long time. There is an excellent effect that can be raised.

또한, 본 발명은 종래와 같이 응축기의 열교환을 위해 별도로 실외기 및 송풍팬을 구비하지 않아도 되므로서, 설치비용을 대폭 감소시킬 수 있는 장점이 있다.In addition, the present invention does not need to provide an outdoor unit and a blower fan separately for heat exchange of the condenser as in the related art, and has an advantage of greatly reducing installation costs.
