There are two distinct aspects to global warming(also referred to as climate change)in
respect of refrigeration and air conditioning equipment.These are REFRIGERANT SELECTION
and ENERGY EFFICIENCY
Hydrofluorocarbons (HFCs) are a familly of refrigerants that have been specifically developed to
provide alternatives to CFCs and HCFCs.
They have many of the favourable characteristics of CFCs especially those of zero flammability
and zero toxicity.However,HFCs are powerful greenhouse gases that are identified in the Kyoto Protocol(the
international agreement to limit emissions of greenhouse gases).Purchasers
of refrigeration systems should try to minimise emissions of global warming refrigerants.This can be done by;
- minimising leakage of HFC refrigerants to the lowest practical level
- or by using low Global Warming Potential refrigerants such as ammonia or HCs(hydrocarbons)

The major part of greenhouse gas emissions from refrigeration and air conditioning systems
is related to the electricity used to operate them.Generation of electricty leads to CO2 emissions from power stations.On average about 85% of greenhouse gas emissions from UK refrigeration
systems relates to the energy related CO2 and only 15% relates to emissions of high Global Warming
Potential refrigerants.Clearly it is essential that purchasers and operators of refrigeration systems consider all potential environmental impacts,including the energy efficiency
of their equipment.
The practice of recycling our waste,using
long lasting low energy light bulbs
and ensuring that all non essential electrical equipment (including computer equipment) is
switched off whilst not in use,are examples of the way we have integrated our environmental policy into our
daily business activity.
