Central air-conditioning terminal machine fan coil advantages and disadvantages

As a central air-conditioning fan coil end product in the end what kind of advantages and disadvantages, before allowing a large number of consumers.

Independent fan coil plus fresh air system is semi-centralized air-conditioning system has the advantage:

It can be independently controlled room for smaller multi-room; air volume control convenience, can meet the general noise requirements; small footprint, which will help reduce storey building. Thus, this form has been widely used in engineering.

But there are two major drawbacks:

① prone to flooding ceiling;

② due to coil filth and bacteria.

High static pressure duct fan coil unit,

These two shortcomings are due to the current operation of fan coil unit in wet conditions. When using dry-running conditions, it can avoid the wet condition of the coil surface wet dirt accumulation, produce mold problems in order to improve air quality, air-conditioned room. Meanwhile, dry conditions fan coil air conditioning system there is no need to set the condensate system can reduce construction costs and prevents condensation drip water damage on the building and decoration materials caused. In recent years, with the country people attach great importance to indoor air quality, make people aware of the importance of maintaining a clean, dry air conditioning. Thus, these advantages the system dry conditions gradually pay attention to engineering staff.

Currently, scholars respected air treatment "wet and dry separation" program that fresh air and indoor moisture load borne by a separate air handling units, indoor sensible heat load borne by the fan coil air-conditioning in the room, this is a good new ideas. But to implement this program, but also faces many research and solve new problems.
