Description

항온항습 공조설비{Constant temperature and humidity air conditioning system}Constant temperature and humidity air conditioning system

본 발명은 항온항습 공조설비에 관한 것으로, 좀 더 구체적으로는 냉동사이클의 응축열원을 난방열원으로 대체하여 에너지를 절감할 수 있는 항온항습 공조설비에 관한 것이다. The present invention relates to a constant temperature and humidity air conditioning equipment, and more particularly to a constant temperature and humidity air conditioning equipment that can save energy by replacing the condensation heat source of the refrigeration cycle with a heating heat source.

일반적으로, 첨단산업(디스플레이, 반도체, 정밀기계, 제약, 실험실, 병원)의 발전은 각 공정의 집적화, 정밀화, 무균화를 가져왔고 이에 따라 각 산업의 특성에 맞게 항온.항습 및 고청정화를 필요로 하는 공정들이 증가하면서 온.습도에 대한 빠른 응답이 요구되어짐에 따라 각 첨단작업장의 부하에 따른 크린룸 항온.항습공조기의 설치가 매년 증가되고 있다.In general, the development of high-tech industries (displays, semiconductors, precision instruments, pharmaceuticals, laboratories, hospitals) has resulted in the integration, refinement and asepticization of each process, which requires constant temperature, humidity and high cleanliness according to the characteristics of each industry. As the number of processes increases, the installation of clean room constant temperature / humidity air conditioners according to the load of each high-tech workplace is increasing every year.

위와 같이 첨단산업의 에너지 소비량은 공조설비가 크게 좌우하며 외기부하 및 송풍동력 발열부하가 공조에너지에서 95%를 차지하고 있다.As mentioned above, the energy consumption of high-tech industries is largely dependent on the air conditioning equipment, and the external load and the blowing power heating load account for 95% of the air conditioning energy.

좀 더 구체적으로 설명하면, 항온합습 공조 설비는 여름철 고온다습한 환경에서 냉각제습을 사용하여 부하처리를 한다. 이는 온도 제어를 위해 필요한 냉방부하 이상의 냉각이 필요하고 따라서 온도는 설정온도보다 낮게 형성되게 된다. 이를 해결하기 위해 여름철에도 전기 또는 증기 방식의 난방(재열)장치가 가동됨으로써 전기에너지 소비가 현격하게 증가되는 원인이 된다.More specifically, the thermo-hygrostat air conditioning equipment is subjected to load treatment using cooling dehumidification in a high temperature and high humidity environment in summer. This requires cooling above the cooling load required for temperature control and thus the temperature is formed to be lower than the set temperature. In order to solve this problem, electric or steam heating (reheating) is operated even in summer, which causes a significant increase in electric energy consumption.

본 발명의 실시예들은 항온항습 공조설비의 난방열원(재열부하)를 냉동사이클의 응축열원으로 대체하여 에너지를 절감할 수 있는 냉동사이클을 이용한 항온항습 공조설비를 제공하기 위한 것이다.Embodiments of the present invention are to provide a constant temperature and humidity air conditioning system using a refrigeration cycle that can save energy by replacing the heating heat source (reheat load) of the constant temperature and humidity air conditioning equipment with the condensation heat source of the refrigeration cycle.

본 발명의 실시예들은 냉동사이클의 증발열원을 이용하여 부가 냉방이 가능한 항온항습 공조설비를 제공하기 위한 것이다.Embodiments of the present invention are to provide a constant temperature and humidity air conditioning equipment capable of additional cooling using the evaporation heat source of the refrigeration cycle.

When the refrigerant pressure of the measuring device rises above the reference value, the fan of the evaporator is referred to. The above can be controlled.

또한, 상기 제어부는 상기 응축기의 응축온도가 50도 이하로 내려가면 상기 압축기의 회전수 및 상기 증발기의 팬 회전수를 제어할 수 있다.The controller may control the rotation speed of the compressor and the fan rotation speed of the evaporator when the condensation temperature of the condenser drops below 50 degrees.

냉동 사이클(400)은 냉매를 고온고압으로 압축시키는 압축기(410), 압축기에서 고온고압의 냉매를 액상으로 응축하는 응축기(condenser)(420), 증발기(450)로 공급되는 고온고압의 액상 냉매를 교축작용에 의하여 저압상태의 냉매로 팽창시켜 증발 작용이 용이하게 수행되도록 냉매를 감압 팽창시키는 제1팽창 밸브(expansion valve)(440), 제1팽창밸브(440)를 통과한 저온저압의 액상 냉매가 열교환을 통해 기화되는 증발기(450)를 포함한다. 냉동 사이클(400)의 냉매 라인상에는 안전 스위치, 유분리기, 액분리기 등의 통상적인 구성들이 설치될 수 있으며, 이에 대한 설명은 생략한다. The refrigerating cycle 400 is a compressor 410 for compressing the refrigerant at high temperature and high pressure, a condenser 420 for condensing the refrigerant at high temperature and high pressure in the liquid phase, and a high temperature and high pressure liquid refrigerant supplied to the evaporator 450. The low-temperature low-pressure liquid refrigerant passing through the first expansion valve 440 and the first expansion valve 440 to expand and decompress the refrigerant under a throttling action so that the refrigerant is expanded under reduced pressure so as to easily evaporate. Evaporator 450 which is vaporized through heat exchange. On the refrigerant line of the refrigeration cycle 400, conventional components such as a safety switch, an oil separator, a liquid separator, and the like may be installed, and a description thereof will be omitted.

여기서, 응축기(420)의 응축코일(422)은 냉각 코일(310)에 의해 온도가 떨어진 공기의 난방열원을 냉동 사이클(400)의 응축열원으로 대체하기 위해 메인덕트(100)에 설치된다. 즉, 응축기(420)의 응축코일(422)은 메인덕트 내에서 냉각 코일(310)에 의해 차갑고 저습하게 열교환된 공기를 적정 희망 온도로 가열한다. Here, the condenser coil 422 of the condenser 420 is installed in the main duct 100 to replace the heating heat source of the air whose temperature has been dropped by the cooling coil 310 with the condensation heat source of the refrigerating cycle 400. That is, the condensation coil 422 of the condenser 420 heats the air that is cold and low-humidified by the cooling coil 310 in the main duct to an appropriate desired temperature.

여기서, 본 발명의 응축코일(재열코일)의 에너지량은 1kW당 3,560kCal/hr로 기존 전기 방식의 난방재열코일의 에너지량 1kW당 860kCal/hr보다 효율이 높음을 알 수 있다. Here, the energy amount of the condensation coil (reheat coil) of the present invention is 3,560 kCal / hr per 1 kW, it can be seen that the efficiency is higher than 860 kCal / hr per 1 kW of the energy amount of the conventional heating reheating coil.

냉동 사이클(400)의 증발기(450)는 메인 덕트(100)의 상부에 다른 배관들과의 간섭을 최대한 줄여 설치함으로써 부가 냉방으로 사용할 수 있다. The evaporator 450 of the refrigerating cycle 400 may be used as additional cooling by installing the uppermost portion of the main duct 100 to minimize interference with other pipes.

본 발명의 항온항습 공조설비(10)에서는 증발기(450)의 팬(미도시됨) 가동 제어를 통해 응축기(420)의 응축부하 용량을 콘트롤할 수 있다. In the constant temperature and humidity air conditioning system 10 of the present invention, the condensation load capacity of the condenser 420 may be controlled through a fan (not shown) operation control of the evaporator 450.

한편, 응축기(420)에는 냉매 압력을 측정하는 측정센서(490)가 설치되고, 제어부(480)는 측정 센서(490)로부터 제공받은 측정값에 따라 증발기(450)의 팬 가동을 제어할 수 있다. On the other hand, the condenser 420 is provided with a measuring sensor 490 for measuring the refrigerant pressure, the control unit 480 may control the operation of the fan of the evaporator 450 according to the measured value provided from the measuring sensor 490. .

일 예로, 제어부(480)는 응축기(420)에 설치된 측정기(490)의 냉매압력이 기준값 이하로 떨어지면 증발기(450)의 팬 동작을 정지시키거나 또는 기준이하로 제어하고, 측정기(490)의 냉매압력이 기준값 이상으로 올라가면 증발기(450)의 팬을 기준이상으로 제어할 수 있다. For example, the control unit 480 stops the fan operation of the evaporator 450 or controls below the reference value when the refrigerant pressure of the meter 490 installed in the condenser 420 falls below the reference value, and the refrigerant of the meter 490 is controlled. When the pressure rises above the reference value, the fan of the evaporator 450 may be controlled above the reference value.

여기서, 응축기(420)의 응축온도 및 냉매압력은 50도, 18kg/cm2 를 기준값으로 설정한다. 응축기(420)의 응축온도가 50도 이하로 내려가면 압축기(410)의 회전수 및 증발기(450)의 팬 회전수를 제어한다.Here, the condensation temperature and the refrigerant pressure of the condenser 420 is set to 50 degrees, 18kg / cm 2 as a reference value. When the condensation temperature of the condenser 420 falls below 50 degrees, the rotation speed of the compressor 410 and the fan rotation speed of the evaporator 450 are controlled.

이와 같이, 본 발명은 고온 다습한 여름철에 난방(재하)부하를 냉동 사이클의 응축열원을 이용하여 에너지를 80% 이상 절감할 수 있다. 이에, 습도 변화에 따른 난방(재열)부하의 변동폭이 잦아 압축기의 잦은 기동으로 인한 소손을 해결하기 위해 압축기의 PID 제어를 통한 압축기의 속도조정 및 기동,정지를 원활하게 한다. As described above, the present invention can reduce energy by 80% or more by using a condensation heat source of a refrigeration cycle in a heating (load) load in a hot and humid summer season. Therefore, the fluctuation of the heating (reheat) load due to the change of humidity is frequent, so as to solve the burnout caused by frequent starting of the compressor, the speed adjustment, starting and stopping of the compressor through PID control of the compressor is smoothed.
