8.1 AMBIENT TEMPERATURE
The ambient temperature surrounding the system strongly influences the compressor working conditions.
The system must be designed and tested in order to ensure that the compressor works (at normal and
abnormal expected conditions in the field) within its admitted limits (see Chapter
8.4 - Operating envelopes)
at the max ambient temperature where the system will be installed.
A functional and efficient refrigeration system is the combination of various components, properly selected
and assembled in order to reach the pursued safety level and performance of the finished product and
respecting the admitted limits of each component.
The compressor is one of the system components: the information of these installation instructions relates
only to the Embraco compressors with their standard electrical components and accessories.
8. OPERATING CONDITIONS
8.2 COMPRESSOR SELECTION
The hermetic scroll compressors are very specialized machines, designed:
a) to work with a specific refrigerant
b) for a specific type of application (LBP or MBP)
c) for electrical supply at 50 or 60 HZ with a certain supply voltage
d) to deliver a certain cooling capacity
e) to operate in certain admitted working range
f) to be properly installed
Correct function of defined compressor and related electrical accessories is
possible only if requirements mentioned in points a)...f) are assured. Working out
of the defined limits may result in malfunction of the compressor caused damages
to properties and injuries to persons.
The compressor cooling capacities at various evaporating temperatures, with condensing temperatures as
parameter are indicated in the Technical datasheets in the
Embraco Product Selector on www.embraco.com
For each compressor use only the refrigerant indicated in Table
6.2 Approved
refrigerants. Usage of different refrigerant can generate abnormal working
conditions, excessive pressure in the refrigeration system, damages of the
compressor and explosions.
