Energy evaluating system for central air conditioning systems

With the projects in Wuhan, presents the operating hours of central air conditioning system under equivalent full load in typical buildings. Discuss several methods of calculating annual energy consumption and the energy evaluating system. Considers the peripheral annual load coefficient (PAL) and the coefficient of energy consumption for air conditioners (CECAC) as effective indexes for evaluating central air conditioning system design in China. But there is no constraint boundary conditions when CECAC is used to evaluate the design induced by slightly-large calculation load. Suggests working out the PAL and CECAC criteria suitable for our country as soon as possible.
