What is claimed is: 1. A sub-unit for a refrigerant circuit comprising: a condenser; a chiller in fluid communication with said condenser; a high pressure fluid line coupled to said condenser and extending to a free end; a low pressure fluid line coupled to said chiller and extending to a free end;

What is claimed is: 1. A sub-unit for a refrigerant circuit comprising: a condenser; a chiller in fluid communication with said condenser; a high pressure fluid line coupled to said condenser and extending to a free end; a low pressure fluid line coupled to said chiller and extending to a free end; a refrigerant in said condenser and in said chiller and in said lines; and a valve unit disposed on each of said free ends for retaining said refrigerant in said sub-unit and each of said valves has a normally closed position and is movable to an open position in response to connection to a connector for allowing said refrigerant to flow into and out of said lines. 2. A sub-unit as set forth in claim 1 wherein said valve unit defines a snap together coupling with the connector that moves said valve unit to said open position when said valve unit and the connector are snapped together. 3. A sub-unit as set forth in claim 2 further comprising an expansion device interconnecting said condenser and said chiller. 4. A sub-unit as set forth in claim 3 further comprising a receiver interconnecting said chiller and said condenser. 5. A sub unit as set forth in claim 4 further comprising an accumulator interconnecting said chiller and said free end. 6. A sub-unit as set forth in claim 5 wherein said condenser is connected to said chiller. 7. A sub-unit for a refrigerant circuit comprising: a condenser; a chiller in fluid communication with said condenser; said condenser is disposed above and connected to said chiller; an expansion device interconnecting said condenser and said chiller; a receiver interconnecting said chiller and said condenser; a high pressure fluid line coupled to said condenser and extending to a free end; a low pressure fluid line coupled to said chiller and extending to a free end; an accumulator interconnecting said chiller and said free end; a refrigerant in said condenser and in said chiller and in said lines; a valve unit disposed on each of said free ends for retaining said refrigerant in said sub-unit and each of said valves has a normally closed position and is movable to an open position in response to connection to a connector for allowing said refrigerant to flow into and out of said lines; and said valve unit defines a snap together coupling with the connector that moves said valve unit to said open position when said valve unit and the connector are snapped together. 8. A vehicle comprising: a body defining an engine compartment having a front and a rear in spaced relationship to said front; a sub-unit for an air-conditioning circuit disposed within said engine compartment and including: a condenser, a chiller in fluid communication with said condenser, a high pressure fluid line coupled to said condenser and extending to a free end, a low pressure fluid line coupled to said chiller and extending to a free end, a refrigerant in said condenser and said chiller and said lines, a connector in fluid communication with a compressor, and a valve unit disposed on each of said free ends for retaining said refrigerant in said sub-unit and each of said valve units defining a normally closed position and being movable to an open position in response to connection to said connector for allowing said refrigerant to flow into and out of said lines. 9. A sub-unit as set forth in claim 8 wherein said sub-unit is disposed at said front of said engine compartment for permitting airflow to said condenser. 10. A sub-unit as set forth in claim 9 wherein said valve unit and said connector further define a snap together coupling that moves said valve unit to said open position when said valve unit and said connector are snapped together.
