Definitions
- the present invention relates generally to air conditioning systems for motor vehicles and, more specifically, to a condenser with an integral receiver dryer for an air conditioning system in a motor vehicle.
- the condenser typically receives a fluid such as a refrigerant in a vapor phase, at a reasonably high temperature, and cools the vapor phase to transform it to a liquid phase.
- the condenser normally includes a plurality of tubes extending between opposite headers.
- the condenser also includes a plurality of cooling fins disposed between the tubes.
- One type cf condenser often referred to as a multi-pass condenser, includes a plurality of baffles placed in one or both of the headers to direct the refrigerant through a plurality of flow paths.
- a separate receiver dryer for storage of excess refrigerant from the condenser and to remove any moisture from the refrigerant in the air conditioning system.
- An example of a separate receiver dryer for a condenser in an air conditioning system is disclosed in U.S. Patent No. 5,755,113.
- a separate receiver dryer fluidly communicates with a condenser.
- the receiver dryer includes a fluid inlet for receiving a two-phase refrigerant mixture from the condenser and two outlets, both of 'which direct refrigerant back to the condenser after phase separation.
- the receiver dryer also includes a quantity of desiccant material to remove moisture from the two-phase refrigerant mixture.
- receiver dryers used with condensers are disclosed in U.S. Patent Nos. 5,537,839, 5,546,761 and 5,666,791.
- these receiver dryers utilize separate containers, which are attached to the header or manifold of the condenser by various means. In some cases, the attached containers do not have the dryer material. Since the receiver dryer is a separate part, it requires additional space, fittings and brackets to attach it to the air conditioning system.
