Abstract
A refrigerant recovery system that includes a compressor having a inlet connected to a refrigeration system from which refrigerant is to be recovered, and an outlet connected through a condenser to a refrigerant storage container. The condenser includes multiple condenser sections, preferably in an integral assembly having parallel independant refrigerant flow paths. Valves alternately and selectively connect the compressor outlet through the several condenser sections to corresponding storage containers, such that differing refrigerants are fed to associated containers through correponding condenser sections without substantial intermixing or contamination.
Claims19
In a refrigerant handling system that includes compressor means having an inlet and an outlet, means for connecting said compressor inlet to a refrigeration source, condenser means for withdrawing heat from and at least partially condensing refrigerant passing therethrough, and means for connecting said condenser means between said compressor outlet and a container for storing refrigerant, the improvement for handling differing types of refrigerants wherein:
- said condenser means comprises at least first and second condensers having independent refrigerant flow paths, and
- said condenser connecting means comprise means for selectively connecting said compressor outlet alternately through said first and second condensers to the storage container such that differing refrigerants are fed to associated containers through corresponding condensers without substantial intermixing or contamination.
In refrigeration apparatus that includes a compressor for pumping refrigerant and condensing means coupled to the compressor for extracting heat from and condensing refrigerant passing therethrough, a method of handling different refrigerant types in said apparatus comprising the steps of:
- (a) providing said condensing means in the form of a multiple-section condenser having separate parallel refrigerant flow paths, and
- (b) selectively directing refrigerant from said compressor through said condenser sections as a function of type of refrigerant passing through said compressor.
