Extension of a method of calculation of consumption of air conditioners

To evaluate innovations and efficiency as regards air-conditioning, it is necessary to know for how long and in which conditions the equipment functions, an indication related with the COOLING LOAD and which is their effectiveness - EER - on average (or Seasonal) known as SEER. We extended the concept of SEER to include all sources of electricity consumption, namely the secondary equipment, and we called this extended concept the SYSTEM SEER. We know that such figures are highly uncertain and difficult to predict for one single building but we want to give a reasonable estimate and to help the final customer to search for optimum levels of efficiency, without having always to make use of detailed simulation programs. We extend here our method for SSEER calculation to Central Systems.
