Abstract
An oil collector unit of a refrigerant recovery system includes a housing, an interior middle vertical wall disposed in the housing, an interior middle horizontal wall disposed in the housing and intersecting the interior vertical wall and defining left and right pairs of upper and lower chambers on opposite sides of the middle vertical wall having passageways between the upper and lower chambers at opposite ends of the middle horizontal wall which are spaced from the opposite ends of the housing, and a plurality of tubes connected in flow communication with selected ones of the chambers of the housing so as to define a circuitous flow path through the chambers of the housing permitting travel of a fluid mixture of refrigerant and oil therethrough and separation of oil from refrigerant therewithin.
Claims21
An oil collector unit for use in a refrigerant recovery system, said unit comprising:
- (a) a housing defining an interior cavity;
- (b) a substantially vertical interior wall in said housing extending substantially intermediately thereof across said interior cavity and mounted to said housing;
- (c) a substantially horizontal interior wall in said housing extending substantially intermediately thereof across said interior cavity and mounted to said vertical interior wall to define right and left pairs of upper and lower chambers on opposite sides of said vertical interior wall and on opposite sides of said horizontal interior wall, said upper and lower chambers of each pair interconnected in flow communication;
- and
- (d) a plurality of tubes connected in flow communication with selected ones of said chambers of said housing so as to define a circuitous flow path through said chambers of said housing permitting travel of a fluid mixture of refrigerant and oil therethrough and disengagement of oil from refrigerant therewithin, said plurality of tubes including first, second and third tubes defining said circuitous fluid flow path into an inlet and through said first tube, then from said first tube into and through one of said pairs of said upper and lower chambers of said housing, then from said housing through said third tube, then from said third tube back into said housing through the other of said pairs of said upper and lower chambers of said housing and, finally, from said housing and through said second tube to an outlet.
An oil collector unit for use in a refrigerant recovery system, said unit comprising:
- (a) a housing having a continuous tubular wall and a pair of opposite end walls attached to and enclosing opposite open ends of said tubular wall so as to define an interior cavity in said housing;
- (b) a substantially vertical interior wall in said housing extending substantially intermediately thereof across said interior cavity and mounted to said tubular wall;
- (c) a substantially horizontal interior wall in said housing extending substantially intermediately thereof across said interior cavity and mounted to said vertical interior wall at opposite sides thereof and extending in opposite directions from said vertical interior wall to define right and left pairs of upper and lower chambers on said opposite sides of said vertical interior wall and on opposite sides of said horizontal interior wall, said upper and lower chambers of each pair interconnected in flow communication;
- (d) drain means connected with said housing in flow communication with said lower chamber of each of said pair of upper and lower chambers;
- and
- (e) a plurality of tubes connected in flow communication with selected ones of said chambers of said hosing so as to define a circuitous flow path through said chambers of said housing permitting travel of a fluid mixture of refrigerant and oil therethrough and disengagement of oil from refrigerant therewithin, said plurality of tubes including first, second and third tubes defining said circuitous fluid flow path into an inlet and through said first tube, then from said first tube into and through one of said pairs of said upper and lower chambers of said housing, then from said housing through said third tube, then from said third tube back into said housing through the other of said pairs of said upper and lower chambers of said housing and, finally, from said housing and through said second tube to an outlet.
