example you can look at the EER, which is the ratio of the cooling
capacity. The higher the EER rating, the more efficient the air
conditioner. The coefficient of performance or COP– that of a heat
pump, refrigerator or air conditioning system is a ratio of useful
heating or cooling provided to work required is another example.
The higher COPs equate to lower operating costs. Lastly, the
seasonal efficiency of refrigeration equipment, chillers and air
conditioners is often rated by the European seasonal energy
eld at the Westville Country Club in February, things
were kicked off by introducing new members, handing
out certificates and giving a general overview of what can be
expected from the Centre this year.
Once the formalities were out the way, Muller took to the
podium talking about energy saving in the HVAC industry. He
gave a brief background to the amount of energy that a building
consumes looking at cooling, heating, hot water, refrigeration
and fresh air regulations.
Reports suggest that load shedding will be around for the
next 16 months – businesses are looking at viable solutions and
alternatives to survive. “PV systems, energy efficiency, capital
costs, service /maintenance, and return on investments are all
factors to consider. With the draw of power on a building being
40-50% the HVAC industry is responsible for assisting clients to
make wise choices when buying any HVAC system,” Muller said.
Government has introduced a minimum energy standard in
all electrical appliances, including air-conditioning. The Standard
states that the energy consumption or level can’t be anything
below a B class energy rating, “But who looks at this?” he asks.
Airconditioning split units all now come with an energy rating, for
