Description

냉난방 보일러 열 효율 장치{Air conditioning boiler thermal efficiency system}Air conditioning boiler thermal efficiency system

본 발명은 냉난방장치에서 냉매압이 일정하게 유지하게 하는 것으로, 특히 혹한기 난방시에 냉매압이 현저하게 낮아지는것을 근본적으로 일정하게 하는 냉난방장치에 관한 것이다.The present invention is to maintain a constant refrigerant pressure in a heating and cooling device, and more particularly relates to a cooling and heating device that essentially makes the refrigerant pressure significantly lower during cold heating.

일반적으로 히트 펌프를 이용한 냉난방장치는 하나의 장치에서 선택적으로 냉방 싸이클과 난방 싸이클을 운전하여 냉방 및 난방을 할 수 있도록 하는데, 이러한 종래의 냉난방장치는 도3에 도시한 바와 같이, 압축기(1), 전자사방변(3), 열교환기(5), 팽창변(7), 증발기(9)로 구성되어 있다.In general, a heating and cooling device using a heat pump enables cooling and heating by selectively operating a cooling cycle and a heating cycle in a single device. As shown in FIG. 3, the conventional cooling and heating device includes a compressor (1). , An electron four sides 3, a heat exchanger 5, an expansion valve 7, and an evaporator 9.

난방 운전 과정을 설명하면, 압축기(1)에 의해 압축된 고온고압의 액체상태 냉매는 전자사방변(3)을 통해 열교환기(5)로 유입되어 열교환에 의해 실내에 난방을 행한 다음 저온고압의 상태가 되고, 이러한 저온고압의 냉매는 팽창변(7)으로 유입되어 팽창됨으로써 저온저압의 상태가 된다.Referring to the heating operation process, the high-temperature, high-pressure liquid state refrigerant compressed by the compressor (1) flows into the heat exchanger (5) through the electron four-sided (3) to heat the room by heat exchange, and then The low temperature and high pressure refrigerant flows into the expansion valve 7 and expands into a low temperature and low pressure state.

이러한 저온저압의 냉매는 증발기(9)에서 증발되어 기화되고, 이때 증발되어 기체 상태의 냉매는 고온저압 상태가 되어 다시 전자사방변(3)을 통해 압축기(1)로 유입됨으로써 난방 싸이클을 이룬다.The low temperature low pressure refrigerant is evaporated and evaporated in the evaporator 9, and at this time, the refrigerant in the gas state becomes a high temperature low pressure state and flows back into the compressor 1 through the electron four sides 3 to form a heating cycle.

냉방 운전의 경우 난방 싸이클의 역 싸이클이 되는데, 압축기(1)에 의해 압축된 고온고압의 냉매는 전자사방변(3)을 통해 증발기(9)로 유입되어 응축되고, 이러한 응축된 냉매는 팽창변(7)에서 단열팽창하여 저온저압의 냉매가 된다.In the case of the cooling operation, it becomes the reverse cycle of the heating cycle. The refrigerant of the high temperature and high pressure compressed by the compressor 1 flows into the evaporator 9 through the electron four sides 3 and condenses. It expands adiabatic in 7) and becomes low temperature low pressure refrigerant.

팽창변(7)에서 응축된 냉매는 열교환기(5)에서 열을 흡수함으로써 실내를 냉방하게 되고, 이로인해 저온의 냉매는 전자사방변(3)을 통해 압축기(1)로 유입되어 다시 고온고압의 냉매로 압축된다.The refrigerant condensed in the expansion valve (7) absorbs heat in the heat exchanger (5) to cool the room, whereby the low-temperature refrigerant flows into the compressor (1) through the electron four sides (3) and again at high temperature and high pressure. Compressed to the refrigerant.

그런데, 이와같은 난방 싸이클의 경우에는 냉매가 온도에 민감하여 혹한기 냉매압이 현저하게 낮아진다.However, in the case of such a heating cycle, the refrigerant is sensitive to temperature, so the cold air refrigerant pressure is significantly lowered.

이러한 냉매압 저하로 혹한기 난방 효율이 급격하게 떨어지는 문제점을 안고 있다Due to such a decrease in refrigerant pressure, the heating efficiency of the cold weather drops sharply.

이러한 문제점을 해결하고자 본 발명은, 냉매를 일정압 이상으로 될 때 저압쪽 전자변은 닫히고 고압쪽 전자변은 열려서 냉매 보관통에 냉매가 가득 담겨 있다가 혹한기 냉매압이 낮아질때 고압쪽 전자변은 닫히고 저압쪽 전자변이 열려서 냉매가 저압쪽으로 유입되어 냉매압을 일정하게 유지하도록 하여 냉난방장치 효율을 높이는데 그 목적이 있다.In order to solve this problem, the present invention, when the refrigerant is above a certain pressure, the low-pressure side of the electronic valve is closed and the high-pressure side of the electronic valve is opened, the refrigerant reservoir is filled with the refrigerant when the cold refrigerant pressure is low, the high-sided electronic valve is closed and the low-pressure side electronic valve The purpose of this is to increase the efficiency of the cooling and heating system by opening the refrigerant to the low pressure to keep the refrigerant pressure constant.

상기의 목적을 달성하기 위하여, 본 발명의 냉난방장치는 냉매를 고온고압으 로 압축시키는 압축기;In order to achieve the above object, the heating and cooling device of the present invention is a compressor for compressing a refrigerant at high temperature and high pressure;

압축기로부터 나온 고압 냉매관에 T자관을 사용하여 병렬 연결하여 제1 압력SW+제1 전자변+냉매 저장통+제2 전자변+제2 압력SW를 저압쪽 냉매관에 T자관을 사용하여 병렬로 연결되도록 구성한다The T-pipe is connected in parallel to the high-pressure refrigerant pipe from the compressor to connect the first pressure SW + first electron valve + refrigerant reservoir + second electron valve + second pressure SW to the low-pressure refrigerant pipe in parallel by using a T-tube. do

이와 같이 구성된 본 발명은, 혹한기 급격하게 떨어지는 냉매압을 높여줘 일정압으로 유지하여 줌으로써 냉매압 저하로 인한 열 효율을 극대화 시킴으로써 종래와 같이 혹한기 급격하게 떨어지는 냉매압으로인한 난방의 효율이 떨어지지않는다The present invention configured as described above, by increasing the refrigerant pressure drops rapidly during the cold weather to maintain a constant pressure to maximize the thermal efficiency due to the refrigerant pressure drop does not reduce the efficiency of heating due to the cold pressure drops rapidly cold as in the prior art.

따라서 난방 효율이 증가되는 효과가 있다.Therefore, the heating efficiency is increased.

이러한 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 의한 냉난방장치의 구성을 보인 도이고, 도2는 가압기의 구조를 보인 도이다.1 is a view showing the configuration of a heating and cooling device according to the present invention, Figure 2 is a view showing the structure of a pressurizer.

먼저, 난방 운전의 기본적인 동작은 종래와 동일한데, 100(압축기)에서 나온 고압냉매가 701관으로 유입되어서 200(열교환기)702관을 거쳐 300(팽창변)을 통과 하며 703관으로 유입되면서 저압으로 바뀝니다. 600(증발기)를 704관을 통해 110(압축기)로 유입됩니다.First, the basic operation of the heating operation is the same as the conventional one, but the high pressure refrigerant from the 100 (compressor) flows into the 701 tube, passes through the 200 (heat exchanger) 702 tube, passes through the 300 (expansion valve), and enters the 703 tube to low pressure. Will change. 600 (evaporator) enters 110 (compressor) through 704 pipe.

705관을 저압관인 704혹은 600혹은 703관에 병렬(T모양)로 연결하여 501(제2압력 SW)저압냉매 압력을 측정하여 냉매압이 높을때는 401(제2 전자변)이 닫힌다 냉매압이 낮을때는 401(제2 전자변)이 열린다Connect 705 pipe to low pressure pipe 704, 600 or 703 pipe in parallel (T-shape) and measure 501 (second pressure SW) low pressure refrigerant pressure and close 401 (second electromagnetic valve) when the refrigerant pressure is high. 401 (the second electron valve) opens

706관을 고압냉매인 701혹은 200혹은 702관에 병렬(T모양)로 연결하여 500(제1압력 SW)고압냉매 압력을 측정하여 냉매압이 높을때는 400(제1 전자변)이 열려서 402(냉매 저장 탱크)에 유입되고 냉매압이 낮을때는 400(제1 전자변)이 닫힌다Pipe 706 is connected in parallel (T-shape) to 701 or 200 or 702 tubes of high-pressure refrigerant, and the high pressure refrigerant pressure is measured by 500 (first pressure SW). 400 (the first electron valve) is closed when it flows into the storage tank and the refrigerant pressure is low.

결국, 본 발명은 대기중 온도 변화에 변동되는 냉매압을 제2 전자변과 제1 전자변을 이용하여 냉매 저장 탱크에 저장해 두었다가 대기 온도가 떨어져 냉매압이 떨어질때 일정 수준의 냉매압을 유지 시켜줘 안정적인 난방효율을 저하시키지 않도록 하는 구조를 갖는 것이다.As a result, the present invention stores the refrigerant pressure fluctuating with the change in the temperature of the atmosphere in the refrigerant storage tank using the second electron valve and the first electron valve, and maintains the refrigerant pressure at a predetermined level when the refrigerant pressure drops due to the drop in the atmospheric temperature. It has a structure which does not reduce efficiency.
