Energy Saving Module(s)(ESM)
represent a green technology that reduces the electricity
consumption (kWh) and maximum demand (kW) of air conditioning and refrigeration
compressors. The system works in conjunction with existing HVAC controls ensuring
that the compressors work at maximum efficiency, while maintaining preset
temperature levels. By preventing over-cycling by a process, known as
‘Compressor Optimisation' consumption of electricity is cut by between 15% and
25% in each case, thereby improving operating costs and cutting emission of greenhouse
gases.
Method of operation
Conventional controls, including
the most sophisticated Building & Energy Management Systems (BEMS) and
state-of-the-art refrigeration controls, operate only on reaching
pre-programmed static values to switch compressors off and on or adjust
capacity. When the measured medium is within the dead band, the BEMS and
controllers remain idle until a specific set value is reached. They do nothing
to dynamically measure the heat load and adjust the control differential in
proportion to the cooling demand or to dynamically control the cycle rate of
the compressors.
The ESM is a microcomputer that
records the absolute switching values of the primary controller and also
measures the 'rate of change' of both the rise and fall of temperatures during
the operating cycle of the compressors. With this data the ESM computes a
reference heat load to match the cooling capacity and then calculates variable
operating parameters. This calculation is used to minimise compressor operation
within the absolute switching values, with a resultant reduction in
refrigeration and air conditioning compressor run time, reduced electricity
consumption (kWh) and maximum demand (kW/KVA). This is achieved while
maintaining the original operating temperature.
