A/C Usage

Vehicles > A/C Usage

In this form the user provides the number of vehicles equipped with air-conditioning system (Vehicles equipped with A/C(%)). Some 'default' values are proposed which are rough estimates only. More detailed data can be obtained from national statistics. In general, the number of passenger cars equipped with an A/C increases for late models. One also needs to estimate the A/C usage (Usage(%)), as a percentage fraction of the vehicle operation. For simplicity, one single usage factor is proposed regardless of urban, rural, or highway driving. This usage factor is uniformly applied to all driving conditions. This usage factor should be integrated over the year, i.e. there is no seasonal differentiation.
