(2) the room is a layer of air conditioning room, indoor air conditioner vertical air conditioning chilled water through the feed line to each layer, the vertical air conditioning air conditioner after packed into the return pipe condensed water to nearby principle into toilet drains, dealing with water seal to prevent gas back before access.
When summer cooling water cooled air conditioning water system startup sequence is:
Cooling tower cooling water inlet pipe electric butterfly valve, cooling water pump, cooling tower fan, &water-cooled packaged in cooling water circulation (by water flow switch) confirmed after open compressor, stop.
Full air speed of air conditioning system: return air mixes with fresh air to enter air processor machine after heat treatment and pressure through silencing plenum into the duct, the diffuser and the double shutter into indoor. Indoor cooling load change, by the air conditioner inlet temperature controller automatically adjust perfectly on the return pipe unit with proportional.
This design reference a large number of documents, manuals, pictures engineering instance. Strive for the best combination of various aspects. But due to the limitation of materials and levels of low, some omission and error is inevitable, hope I can along with the development of their own learning progress and research will do my best. Thank you for your teachers can criticize and correct me, so I could get a more reasonable design scheme.
