Mechanical cooling is the reducing of the temperature of a gas or liquid by using vapor compression, absorption, desiccant dehumidification combined with an energy driven thermodynamic cycle.
A bigger system is not always better! An over sized air conditioning system will rapidly cool a building, which results in short cycling of the system. It takes a certain amount of time and depending on the heat load, to properly dehumidify and reduce the temperature. Most Certainly, an undersized system will run constantly on a hot summer day. An adequately sized air conditioning system will:
