Introduction 1
Introduction
Fan coil unit is a kind of compound device which assemble fan and surface-type coil heating-exchanger
together. Fan coil with fresh air supply system is a main type of center air-conditioner system, so it is an
important component of AC devices. Fan coil has horizontal type, vertical type, etc. A cooling (heating)
supply system usually consists of fan coil terminals and chilled water system (heated water system).
Midea®commercial AC fan coil is designed and manufactured on the base of advanced technology, and
utilize qualified galvanized iron as material. Due to its supper-thin design, it has such advantages: beautiful
outlook, space saving, easy installation, etc. And the most obvious advantage is that it can decrease the
outlet air Temp-difference as low as possible to make room more comfortable, as well as don’t decrease
cooling capacity output. For the large air flow volume design, it can increase room ventilation frequency,
supply more flesh air, and balance room temperature distribution. Benefiting from adoption of advanced
material and technology, it can effectively decrease the running noise and keep running smoothly. With the
advantages above, it can be widely applied in market, hospital, office building, hotel airport, etc.
