Reduce electricity and gas bills with an energy efficient mechanical - HVAC design for your building.
Window air conditioners and packaged terminal air conditioners (PTAC) are similar, since both have all the required components in a unit that goes through the wall. However, these air conditioners create an opening in your building envelope, which reduces the effectiveness of insulation. They are typically the most affordable AC units, but also the least efficient - expect high electricity bills during summer if your building uses window ACs or PTACs.
Split type air conditioners have separate housings for their condenser and evaporator, as their name implies. The condenser is outdoors, the evaporator is indoors, and both units are connected with an insulated refrigerant line. Since there is no gap in your window envelope, split air conditioners are much more efficient than window ACs and PTACs.
Chiller plants are normally used in large commercial and industrial facilities. Instead of cooling the air directly, chillers cool water that is then pumped through the building. The chilled water reaches fan coils, where the cooling effect is delivered to indoor air. Chilled water piping is used when vertical distances are involved, since blowing cold air upwards is unfeasible and a waste of energy.
