Abstract
The receiver dryer includes a cylindrical body with fluid inlet and outlet ports that allow fluid communication between the interior of the body and the refrigeration circuit. The body includes a concave section. The concave section extends downwardly of the bottom portion of the body. A fluid outlet pipe extends into the interior of the concave portion. Therefore, the receiver dryer can reduce the refrigerant volume in the refrigeration circuit without decrease of the refrigerating capacity, since the receiver dryer promotes separation of liquid and gaseous refrigerant. Thus, the receiver dryer can be made compact.
Claims20
A receiver dryer for a refrigeration circuit comprising:
- a hollow cylindrical body having fluid inlet and liquid outlet ports providing fluid communication between the interior of said cylindrical body and said refrigeration circuit;
- a bottom portion closing one end of said cylindrical body;
- a concave section attached to said bottom portion of said cylindrical body, said concave section forming a separate part of said bottom portion and extending downwardly therefrom and including a closed end;
- and
- a liquid outlet pipe connected directly to said outlet port, said liquid outlet pipe extending into the interior of said concave section.
In a refrigeration circuit, a receiver dryer comprising:
- a hollow cylindrical body having an inner diameter;
- a header attached to one end of said cylindrical body, said header having an inlet port and an outlet port;
- a concave section, attached to the other end of said cylindrical body, having a given inner diameter and a given length and including a closed end;
- a liquid outlet pipe attached directly to said outlet port and extending into said concave section;
- and
- wherein said cylindrical body inner diameter is between 3 and 8 times as large as the inner diameter of said concave section, and the length of said concave section is greater than the inner diameter of said concave section.
