Medical equipment purification plant | difference duct machine and central air-conditioning where | Jinan blue bridge purification duct machine is hidden air conditioning short, it's an indoor unit and an indoor unit central air conditioning is basically the same, and is mounted on the ceiling in . Because it is a trailer outside the machine within a machine, so it is not central air conditioning in the true sense. But, delayed more than central air conditioning compared to wind machines are cheap, interior decoration and central air conditioning out the effect of the same. Wind machines and central air conditioning did not really good question, only not suitable for the issue, the advantages of wind machines are: low cost, effectiveness, and central air conditioning as indoor, easy maintenance, more suitable for our air conditioning usage. Disadvantages are: fixed-frequency technology, the outdoor machine, more than Position requirements. Advantages of the central air conditioning: advanced technology higher energy efficiency, outdoor pipe cleaner, less outdoor unit position requirements. Disadvantages are: the cost is slightly higher, slightly higher maintenance costs. Duct machine duct machine definition is ducted air conditioners, air conditioning duct connecting to the indoor air installation for central air-conditioning duct unit Tip 1, and the general air-conditioning installation methods are not the same, small central air conditioning design and installation must be in Prior to home decorating, the host through the ceiling type (even on the bathroom ceiling) installation or loaded into the closet, so the room can not see the host, the overall pattern is more simple and beautiful. This selection of the best design of the project during the construction process installation is complete, otherwise it will affect post-renovation. 2, home central air-conditioning systems generally do not have fresh air, even in the heat pump type air, fresh air replacement can only reach 15%. If you want to achieve better results, additional fresh air system, a lot of real estate to prepare additional new ventilation system in addition to its central air conditioning system. 3, home central air conditioner outdoor unit will have some noise, but not great, but better to install it away from the bedroom balcony. 4, outdoor veranda opportunity occupy an area of ??about one square meter. 5, home central air-conditioning service life is generally about 15 years, when the owners need to spend their own money to replace. Sterile lab - clean laboratory - Biosafety Laboratory building program include: building layout and decoration, air conditioning, plumbing, gas supply, electrical design, centralized control, security, construction technology, testing, training and other aspects of content in particular the following aspects of the program to do very well to consider: 1) building layout and decoration scheme: a clean laboratory - basic biosafety laboratories safe operation. Because of the risk of microbial pathogens, must prevent the proliferation of dangerous microbes to the outside world, fully blocked the route of exposure dangerous microorganisms from the external environment, while avoiding microbial contamination by outside influence the accuracy of the experimental results, the laboratory must take reasonable layout and renovation program. Laboratory safety requirements in accordance with reasonable layout divided into clean areas, semi-polluted and polluted medical dressings purification plant, and things were set using a dedicated channel, set up the necessary buffer between the purification plant, the use of a secondary isolation and quarantine measures can effectively avoid cross-contamination, prevent the proliferation of dangerous microbes from the root; laboratory renovation using reliable materials medical materials purification plant, reasonable construction measures to ensure clean laboratory - Biosafety Laboratory will always be in a relatively closed environment prevent the escape of microorganisms, easy to clean and disinfect the laboratory, while avoiding damage to the outside of the laboratory environment. 2) air conditioning system: a clean laboratory - Biosafety laboratory safety critical operation. 3) Control system: the entire clean laboratory - Biosafety laboratory safety operation of the nerve center. Because clean laboratory - experimental subjects biosafety laboratories are dangerous microbes, for the principle of strict pollution control, which requires a minimum of maintenance personnel, using the most optimized management and maintenance tools bakery purification plant, real-time monitoring of each a physical environment in which the lab equipment, ensure the laboratory is always running at a relatively negative pressure environment, to prevent the leakage of dangerous microbes. 4) detection scheme: a clean laboratory - Biosafety Laboratory ensure long-term safe operation. 5) training programs:
