Summary:The present invention relates to a cooling system in a radiation controlled area. The cooling system in the radiation controlled area includes: a compressor compressing a refrigerant; a condenser condensing the refrigerant passing through the compressor; an outdoor unit including an expansion valve for expanding the refrigerant passing through the condenser and installed on the outside of a radiation controlled area; an evaporator evaporating the refrigerant passing through the expansion valve; an indoor unit including a power unit to receive electricity from the outside and installed on the inner side of the radiation controlled area; a refrigerant pipe connecting the compressor, the condenser, the expansion valve, the evaporator, and the compressor in order and enabling the refrigerant to circulate; a shut-off valve shutting off the refrigerant pipe in order for a radiant matter on the inner side of the radiation controlled area not to leak through the refrigerant pipe, wherein the shut-off valve is installed in the refrigerant pipe; and a control unit for controlling a refrigerating system and installed in a power unit. Therefore, the cooling system in the radiation controlled area shuts off the refrigerant pipe by operating the shut-off valve when a radiation leakage situation occurs in the radiation controlled area. So, the cooling system in the radiation controlled area can prevent a radiation matter from leaking from the radiation controlled area to the outside in advance. 본 발명은 방사선 관리구역에서의 냉방 시스템에 관한 것으로, 냉매를 압축하는 압축기, 상기 압축기를 통과한 냉매를 응축하는 응축기, 상기 응축기를 통과한 냉매를 팽창시키기 위한 팽창밸브를 포함하며 방사선 관리구역의 외측에 설치되는 실외기와, 상기 팽창밸브를 통과한 냉매를 증발시키는 증발기, 외부로부터 전기를 공급받기 위한 전원부를 포함하고 방사선 관리구역의 내측에 설치되는 실내기와, 상기 압축기, 응축기, 팽창밸브, 증발기, 압축기를 차례로 연결하여 냉매가 순환되도록 하는 냉매 배관과, 상기 냉매 배관에 설치되며 방사선 관리구역의 내측의 방사성물질이 상기 냉매 배관을 통해 누출되지 않도록 상기 냉매 배관을 차단하는 차단밸브와, 전원부에 마련되며 냉동 시스템를 제어하기 위한 제어부를 포함하는 것을 특징으로 한다. 따라서, 방사선 관리구역에서 방사선 누출 상황이 발생될 때, 차단밸브가 작동되어 냉매 배관을 차단함으로써, 방사성 물질이 방사선 관리구역 내에서 외부로 누출되는 것을 미연에 방지할 수 있다.
