Based on our compressors of the Pluscom series with its outstanding advantages and features, Bock offers already for some time a
compressor version with 2-pole drive
This compressor version makes mains voltages of 60 Hz possible
and therefore a corresponding higher refrigerating capacity compared to an operation with 50 Hz mains voltage.
This increase in the maximum possible compressor capacity can
be realised through the use of a special valve plate system. The socalled Bock K-valve plate, which was developed by Bock especially
for mobile applications, is already used thousands of times in the
area of bus air-conditioning and sets the international standard for
quality and reliability.

Operating limits
Performance data
Compressor operation is possible within the limits shown on
the application diagrams. Please note the coloured areas.
Compressor application limits should not be chosen for design
purposes or continuous operation.
The performance data for R134a are based on EN 12900 at
50 Hz power supply frequency. This signifies: 20 °C suction
gas temperature without liquid subcooling.
This results in significant differences compared to specifications with liquid undercooling and/or suction-gas temperatures.
For operation with frequency converter:
Minimum frequency = 15 Hz
Maximum frequency = 60 Hz
Performance data for other operating points, see Bock software.
Calculations
Calculating the maximum possible frequency of the
compressor under specific operating conditions:
Calculating the corresponding refrigerating capacity:
The following calculation is used to obtain the maximum
possible frequency at the selected operating point:
Refrigeration capacity can be determined as a function of
frequency from the following calculation:
P x 50 Hz
fmax = max
Pe
fmax =maximum permissible frequency [Hz]
•
f
xQ
Qo operation= operation 0 50Hz
50 Hz
•
•
Qo operation= refrigerating capacity at the chosen
operating point [W]
Pmax = maximum power consumption [kW]
(see technical data, compressors)
f operation = frequency at the chosen operating point [Hz]
Pe =power consumption at the operating point
at 50 Hz [kW] (see performance data, compressors)
Qo 50 Hz = refrigerating capacity at the operating point at
50 Hz [W] (see performance data, compressors)
i
•
As a rule, the maximum permissible power consumption of the compressor Pmax must not be exceeded.
The maximum permissible frequency is always restricted in case of high evaporation temperatures associated
with high condensing pressures with refrigerant R407C.
