R410a tropical air-cooled scroll chiller unit 60Hz
. 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.

    R410a tropical air-cooled scroll chiller unit 60Hz MCAC-ATSM-2014-09 1.4 Features 1).Digital scroll technique,new type air-cooled scroll chiller system. Capacity output is controlled depending on controlling compressor to on/off in traditional modular air-cooled chiller system control. The precise control mode is not perfect, and the compressor is frequently on and off, which is very bad for the compressor’s long-life performance.
  • Page 7 MCAC-ATSM-2014-09 R410a tropical air-cooled scroll chiller unit 60Hz  Leak-tight refrigerant circuit, Brazed refrigerant connections for increased leak-tightness. 4). Economical operation New design adopts electronic expansion valve precise refrigerant control in wider range. Electronic expansion valve allows operation at lower condensing pressure, adjustment can be made fast linear response, making the system output more stable and the indoor temperature more uniform result in better life for human.
