2 Introduction

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 syste m, so it is an important compo nent of AC devices. Fan coil unit has concealed type and exposed type. A cooling (heating) supply system usually consists of fan coil termin als an d c hilled water system (heat ed w at er 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 v olume design, it can increase r oom ventilati on frequency, supply more flesh air, and balance room te mperature distribution. Bene fiting fro m adopt ion of adv an ced mat eria l and t echno lo gy, it can effectively decrease t he running no ise and keep running smoothly. With the advantages above, it can be widely applied in market, hospital, office build ing, hotel, airport, etc.
