Ventilative cooling is the use of natural or mechanical ventilation to cool indoor spaces. The use of outside air reduces the cooling load and the energy consumption of these systems, while maintaining high quality indoor conditions; passive ventilative cooling may eliminate energy consumption. Ventilative cooling strategies are applied in a wide range of buildings and may even be crit…

Cooling, ventilation, and air-conditioning systems in the building

Central cooling systems use a network of ducts to supply air throughout the house. These are usually two-part systems with an outdoor unit that contains the compressor and condenser coils and an indoor unit with evaporator coils. Refrigerant lines link the two together. Ductless Mini-Split Systems are ideal for homes and apartments.
