Clean air-conditioning system in intensive care unit is an indispensable equipment in hospital. At the same time, it plays an important role in the control of infection pathway in intensive care unit. Especially for hospital patients, clean air-conditioning system can reduce the infection rate of operation and cross infection rate in wards, and help patients recover early. Therefore, through the application and maintenance of the clean air conditioning system in ICU, to ensure the stability of the system is of great significance to improve the efficiency of hospital work. So, what are the requirements for the installation of clean air conditioning equipment in ICU?
Clean air-conditioning system ensures the overall control of ICU and flexible use of operating rooms. Therefore, for a large hospital, in order to meet the needs of various operations, the number of operating rooms is large, which requires the installation of multiple clean air conditioning units. Clean air conditioning units should generally be installed in the technical interlayer adjacent to the operating room. In order to reduce the source of dust, technical interlayer should be simply decorated, its ground should be flat and wear-resistant, cement ground can not be sanded, and floor tiles can be used to prevent ground pollution if conditions permit. Top and wall should be brushed. Technical interlayer should also be carefully cleaned up before installation of equipment.
The installation of air filter is the most important link to ensure cleanliness. We should adopt the disposable type in the selection of air filters. Clean rooms are usually coarse, medium and high-efficiency three-stage filters. The medium-efficiency filters in the system are installed in the positive pressure section of the fan. The high-efficiency filters are installed at the end of the supply air and the return air outlet to install medium-efficiency or coarse-efficiency filters. Installation location of coarse, medium and high efficiency tertiary filters directly affects the cleaning effect. Installers must install them strictly in accordance with the design requirements in the process of installation.
High efficiency filter is the main equipment of clean air conditioning system in intensive care unit. Because the filter paper is very fine and easy to be damaged, it can only be disassembled at the time of installation. In addition to avoiding damage, the constructors should also pay attention to tightening the tightening bolts when installing the high-efficiency filters. In addition, enough sealant should be inserted into the seals at the overlap of the frame, otherwise the leakage will directly cause the cleanliness of the intensive care unit to exceed the standard. Temporary intermediate-effect filters must be installed at the air intake to protect the system during commissioning. After the test run, remove the temporary intermediate effect filter and replace it with the high efficiency filter.
