This Applications and Installation Guide is
intended to be a guide for application data/
installation procedures specific to Danfoss
Turbocor compressors. It is not intended to
inform on fundamental safety, refrigeration
and electrical design skills. It is assumed and
presumed that persons using this manual
are appropriately certified and have detailed
knowledge, experience and skills in respect to
designing for and working with high pressure
refrigerants and medium voltage electrical
components (to 1 KV high power AC & DC) as well
as complex control systems.
Some potential safety situations may not be
foreseen or covered in this guide. Danfoss
Turbocor Compressors (DTC) assumes personnel
using this manual and working on DTC
compressors are familiar with, and carry out all
safe work practices necessary to ensure safety for
personnel and equipment.
This Applications and Installation Manual is
divided into the following sections:
•
Overview of the VTT
- provides an overview
of the Variable Twin-Turbo (VTT) series
compressors, including an introduction to the
compressor and drive modules and a brief
explanation of IntraFlow
TM
, a new technology
used in the VTT compressor.
•
Compressor Module
- provides details on
the Compressor Module of the compressor,
including product capacity and application
range, an in-depth description of IntraFlow
TM
technology, maximum pressure alarm and
fault limits.
•
Drive Module
- provides details on the drive
module, an electronic motor controller that
converts AC line power input into a variable AC
waveform output.
•
System Design Guidelines
- provides basic
guidelines and requirements for the design and
manufacture of R134a systems equipped with
DTC VTT series compressors.
•
Installation Guidelines
- describes application/
installation procedures specific to Danfoss
Turbocor VTT compressors.
