5. The selection of the air conditioning system
Fan coil plus fresh air system has the following advantages:
1) room can independently adjust temperature, design technique is relatively simple (and therefore the design risk is small), the localization of equipment, less investment.
2) flexible arrangement, the independent regulation room temperature, turn off the unit room not people can easily (Guan fan), does not affect the other room, thus saving operation cost more than other systems.
3) only need fresh air conditioning room area.
4) with central air conditioner centralized, with scattered in various modulated terminal devices in the room.
5) unit components for assembly, standardization, standardization degree is high, is convenient for the user to select and install.
6) the use of season length.
This project from the energy conservation, environmental protection, easy to install, easy to repair and other point of view, considering the advantages and disadvantages of the three systems, one to three layers as each room on the indoor environment is different, so the use of fan coil system, and in order to ensure that fresh air supply, the air system independent.
