Due to various reason the property (mainly humidity and temprature) of air is continously chages. People lead more productive and healthy lives due to controlled temperatures and humidity in homes. During periods of unusually hot weather, air conditioning has been credited with saving lives. Three system types are available in the global residential market: window room air conditioners, ductless split air conditioning systems and ducted central air conditioning systems.

Daikins is most energy efficient equipment. This reduces energy consumption and the resulting emissions of CO2 (carbon dioxide). Its save power, it is eco friendly, work quitely.

It is based on both the greenhouse gas emissions ("direct effect") and the energy consumed ("indirect effect"). Air conditioning system operation is energy intensive and, consequently, dominates the LCCP. However, it is also important to minimize system leakage and refrigerant loss during installation, commissioning, servicing, decommissioning at the end of life, and ultimate equipment disposal. Other considerations include the system cost and the safety of users, service technicians and the public.
