Abstract
A solvent recovery system in a low temperature dryer constructed so that hot air is blown into a tumbler housing from a heater, and through a tumbler drum to a cooler in a condenser compressor, a gas evaporator, a gas condenser coil, an expansion valve, and valves and piping provide the circulation of cooled and pressurized refrigerant between the heater and the cooler.
Claims4
In a solvent recovery system for use with a dry cleaning system or the like having a tumbler and a blower, the combination of:
- an air heater;
- an air cooler;
- a housing defining an air recirculating path from said tumbler to said air cooler, said air heater, and return to said tumbler, with said blower in said air recirculating path for moving air around said air recirculating path;
- a refrigerant compressor out of said air recirculating path;
- a refrigerant evaporator out of said air recirculating path;
- a heating exchanger in said air heater in said air recirculating path;
- a cooling exchanger in said air cooler in said air recirculating path;
- and
- first means for connecting said refrigerant compressor, said heating exchanger, said refrigerant evaporator and said cooling exchanger in a refrigerant recirculating path while maintaining said refrigerant evaporator out of said air recirculating path.
