Head Pressure Basics
• The head pressure (discharge pressure)
or condensing temperature of a
refrigeration system has a direct impact on
compressor power consumption
• At cooler ambient temperatures it is easier
to liquefy the compressed refrigerant due
to the temperature differential
![Page 24: Watts in Your Business- GV - Apal](https://reader030.vdocuments.us/reader030/viewer/2022012804/61bd2f6e61276e740b102d19/html5/thumbnails/24.jpg)
Head Pressure Reduction
• Optimise the relationship
between the compressor
and condenser
• On average optimising the
head pressure of a system
can achieve a 3-12%
reduction in power
consumption
• Recommended to speak to
your refrigeration contractor
on how/when to implement

Audit FAQs
• What is my demand charge? How can I reduce it?
� Demand is the largest amount of electricity being consumed at
any one point in time
� Load Shifting, Contract Negations, VPO, Power Factor Correction.
See Tariff Fact Sheet.
• Which refrigerant is the “best”?
� HCFC- (R22, R123,R401/2/3/8/9) Phase out
� R427A- R22 replacement initial estimates have 7% efficiency loss
� HFCs- (R143a, R404a, R407a, R410a)
� Ammonia- High capital cost/corrosive
� Natural Hydrocarbons- (propane mixtures) flammable
� CO2- No industry examples

Funding
• Federal Funding
– With the repeal of carbon tax there is some
uncertainty in this area
• State Funding
– VEET/VEEC
– Sustainability Victoria
• Private Funding
– Financing (e.g. CBA)
