ASERCOM certified performance data:
The Association of European Refrigeration Component Manufacturers has implemented a procedure of certifying
performance data. The high standard of these certifications is assured by:
-- plausibility tests of the data performed by experts
-- regular measurements at independent institutes
These high efforts result in the fact that only a limited number of compressors can be submitted. Due to this not all
BITZER compresors are certified until now.
Performance data of compressors which fulfil the strict requirements may carry the label "ASERCOM certified". In this
software you will find the label at the respective compressors on the right side below the field "result" or in the print out of
the performance data. All certified compressors and further information are listed on the homepage of ASERCOM
(www.ASERCOM.org).
Condensing capacity:
The condensing capacity can be calculated with or without heat rejection. This option can be set in the menu PROGRAM/
OPTIONS. The heat rejection is constantly 5% of the power consumption. The condensing capacity is to be found in the
line Condensing cap. (with HR) resp. Condensing capacity.
Data for sound emission:
Data based on 50 HZ apllication (IP-units 60Hz) and R404A if not declared.
Sound pressure level: values based on free field area conditions with hemisperhical sound emission in 1 meter distance.
General remarks regarding sound data:
Listed sound data were measured under testing conditions in our laboratory. For this purpose the free-standing test
sample is mounted on a solid foundation plate and the pipework is connected vibration-free to the largest extend
possible. Suction and discharge lines are fixed in a flexible configuration, such that a transmission of vibrations to the
environment can be largely excluded. In real installations considerable differences might be observed, compared to the
measurements in the laboratory. The airborne sound emitted by the compressor can be reflected from surfaces of the
system and this may increase the airborne sound level measured close to the compressor. Vibrations caused by the
compressor are also transferred to the system by the compressor feet and piping depending on the damping ratio of the
fixings. Thus, the vibrations can induce other components to such an extent that these components contribute to an
increase in airborne sound emission. If required, the transfer of vibrations to the system can be minimized by suitable
fixing and damping elements.

Liquid receiver
Selection of the receivers:
1) "Approx. according to cooling capacity":
The receiver volume is determined by the design of the unit, the operating mode and the function of the receiver
(receiving the complete refrigerant charge in the receiver or only compensating capacity variations). When selected via
cooling capacity, an approximate selection of the receiver is obtained.
Receivers in systems with long pipelines, winter control or in very compact systems should be selected according to
method 2).
2) "According to refrigerant charge in the receiver":
The calculation is made on the basis of the specified refrigerant charge. The receiver volume is determined at 20°C and
at a maximum filling charge of 95% of the possible receiver content.
Compressor units equipped with receiver
The BITZER range of products comprises compressor units with horizontal receivers. In the output window of the
accessories these units, which are included in the standard delivery, are marked with “mounted” in the compressor unit
line. Units that can be mounted, but are not included in the Bitzer delivery program, are marked with “single parts”.
Units in which the compressor does not fit onto the receiver are marked with "--".
