Abstract
A sub-unit for a vehicle air conditioning system is shipped with a condenser, chiller and fluid lines. Snap together couplings are placed on free ends of the fluid lines whereby the sub-unit can be pre-charged, shipped, installed into the front end of a vehicle engine compartment and connected to an air conditioning compressor.
Claims10
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.

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.
