. PREFACE 

Along  higher  quality  building  environment  and  more  sophisticated  building  function,  there  is  now  a  greatly 
demand  for  system  expansion  for  a  flexible  air-condition  system  capable  of  finer  air-conditioning,  thus 
increasing importance of individual air-conditioning systems. On the other hand, due to social significance of 
environmental  and  energy  problems,  elements  such  as  energy-efficiency  and  low  maintenance  are  still 
strongly desired.   

As professional supplier of air condition appliance and service, Midea air condition permanently aims at 
"providing an solution to regulating the optimal environmental temperature "and brings customers with 
comfortable and agreeable environment whenever and wherever possible.

 

Midea, one of the holders of the Digital scroll technology manufacture, launched out the digital Scroll System 
in 2002, has now enhanced the R410A with the digital scroll system special for high ambient used that 
features capacity up to 1040kW. 

This publication contains a variety of information  related to the design and installation of this new unit. We 
hope this information will serve to deepen your understanding of the system, and will help you to efficiently 
develop its highly evolved characteristics.
