The best forms of Energy Efficient Air Conditioning
Most modern HVAC is provided by air-source heat pump technology. Given the usage of non-ozone depleting refrigerants such as R410-A, these systems are generally considered as having the potential to provide energy efficient and low carbon HVAC solutions.
R410-A is an HFC and not an HCFC and it is generally regarded as having zero Ozone Depleting Potential (ODP) though it does have a high Global Warming Potential (GWP). It is wise to be careful when handling and leak avoidance of sealed systems is necessary.
Compared with other sources of heating, Air Source Heat Pump (ASHP) based systems are an improvement in terms of carbon saving. Energy Saving 54.1 MWh/annum Carbon saving 13.9 tCO2/annum compared with 69.4 and 22.9 for Ground Source Heat Pumps and 42 and 23.8
In terms of the estimated payback a period of 11 years for ASHP systems compare favourably with Ground Source Heat Pumps (GSHP) at 44 years and Wind Turbines at 14 years.
As an alternative, with higher environmental credentials there are several UK based companies offering roof mounted ventilation and cooling entirely by natural mean exploiting the principle of Passive Stack Ventilation.
A natural ventilation strategy designed, developed and supplied by one leading manufacturer has assisted Tesco Stores to achieve a zero carbon footprint and BREEAM 'excellent' rating in its new eco stores.
