The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

A recovery and recharge apparatus and method for delivering a dose of fluorescent dye to an air conditioning/HVAC system. A supply line provides for both recovering and recharging of refrigerant into the system. The supply line includes a first segment connected to the recovery and recharge unit and having a single internal conduit for channeling reclaimed refrigerant into the recovery and recharge unit and for channeling refrigerant from the reservoir. A dye compartment is fluidly connected to the first segment and includes an interior cavity with an access panel for permitting access to the cavity for receiving a fluorescent dye material. A second segment is fluidly connected to the dye compartment and has an outlet port for connecting to a low side connection on the air conditioning/HVAC system. Preferably one way valves are located on opposite sides of the dye compartment and allow recovered refrigerant to bypass the dye compartment.

The present disclosure discloses an air conditioner based on a molecular sieve, including a first molecular sieve device, a second molecular sieve device, a reversing valve, and a balancing valve, a refrigerant includes at least one of R600A, R417A, R410C, or R407C, and a depressurization gas includes at least one of hydrogen or helium. An air flow alternately passes through the first molecular sieve device and the second molecular sieve device through the reversing valve, and then flows back through the balancing valve, so that the first molecular sieve device and the second molecular sieve device are regenerated. The first molecular sieve device and the second molecular sieve device are capable of separating a refrigerant from a depressurization gas, and the refrigerant is condensed after reaching a certain concentration to become a liquid refrigerant, and then enters an evaporator again for refrigeration.
