Energy efficient capacity control for an air conditioning system

摘要

An air conditioning system ( 10 ) is provided for cooling a compartment ( 16 ) of a truck when the main engine is not running. The system ( 10 ) includes a variable speed compressor ( 20 ), a variable speed condenser fan ( 22 ), a variable speed evaporator blower ( 24 ), and a controller ( 14 ) configured to optimize the cooling capacity of the system ( 10 ) to the cooling requirements of the compartment ( 16 ) by selectively adjusting the speeds of the variable speed components ( 20,22,24 ).
