1. Introduction

Fan coil unit is a kind of compound device which assemble fan and heat-exchang coil 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 unit has concealed type and exposed type. A cooling (heating) supply system usually consists of fan coil terminals and chilled water system (heated water system).

Maxa

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 Tempdifference 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.
