Study on Energy Saving of the Interlayer Ventilation Walla Used in Clean Operation Rooms
MetadataShow full item record
Recovery energy of the exhaust in air conditioning is very important to clean operating rooms. In disinfected operating rooms, we often use completely fresh air conditioning system in order to maintain cleanliness. All the return air of the air conditioning must be discharged. For recovering the exhaust energy, whole heat exchangers are used, and they may bring cross-infection in clean operating rooms. Cross-infection would negatively affect cleanness. This paper puts forward an air layer inside of a building's external wall that acts as a passageway for air conditioning exhaust, and also providing a place for the thermal exchange of the air conditioning exhaust. This kind of envelope is named an interlayer ventilation wall. There are two advantages. First, it will recover and reutilize the energy that the air conditioning exhaust takes, avoid cross-infection between the fresh air and the exhaust. Second, it will lower the energy loss of the heat exchange through the envelope. The energy saving effect will be very significant in clean operating rooms.
