た。(Prior Art) In automobile coolers or air conditioners, fluorocarbons are used as a refrigerant in the cooling circuit. When this CFC is released into the atmosphere, it has a negative impact on the ozone layer surrounding the earth. For this reason, when disposing of a car, for example, it is necessary to recover fluorocarbons from the cooling circuit in order to prevent the fluorocarbon gas from being released into the atmosphere and to reuse the fluorocarbons, which are produced in limited quantities. Conventionally, in order to recover fluorocarbons, a compressor or a pump has been used to extract the fluorocarbons from the material to be recovered and pour them into a recovery container for recovery.

後の回収フロンと熱交換させるタイプであった。In other words, conventional fluorocarbon recovery devices either suck the recovered fluorocarbons with a compressor and condense them with a condenser, or they suck the recovered fluorocarbons in liquid form and exchange heat with the recovered fluorocarbons after being discharged by the compressor.

い。(Problem to be solved by the invention) In conventional devices, recovered fluorocarbons are normally allowed to pass through the recovery circuit only once, so in order to regenerate the recovered fluorocarbons, a separate pump is installed and the filter/dryer is repeatedly operated. need to pass. Even in this case, the regeneration of fluorocarbons is carried out when a certain amount of fluorocarbon has accumulated in the recovery tank, and after the regeneration, it is necessary to replace the recovery tank. If the recovery tank is not replaced, recovered fluorocarbons before and after regeneration will be mixed together, and therefore this device is not suitable for regeneration while recovery.
また、コンプレッサによる吸引前と吐出後の回収フロン

いう欠点がある。In addition, a type of recovery device that exchanges heat between recovered fluorocarbons before suction by a compressor and after discharge has a drawback in that heat exchange with recovered fluorocarbons cannot be performed after discharge unless the recovered fluorocarbons are liquid.

The fluorocarbons collected in the next recovery tank are divided into gas and liquid, and the liquid fluorocarbons are sent to the evaporation side of the two-system heat exchanger via an expansion valve after coming out of the primary tank. The fluorocarbons supplied and taken out to the outlet side are returned to the suction side of the compressor, and the gaseous fluorocarbons in the primary recovery tank are supplied to the condensation side of the two-system heat exchanger and then recovered in the final recovery tank. A fluorocarbon recovery device is obtained.

The fluorocarbons recovered in this primary recovery tank are separated into gas and liquid. The separated liquid comes out of the primary recovery tank and passes through the expansion valve to the second tank.
After being supplied to the evaporation side of the system heat exchanger, it is returned to the suction side of the compressor. On the other hand, the gaseous fluorocarbons separated in the primary recovery tank are transferred from the primary recovery tank to the secondary recovery tank.
It is fed to the condensing side of the system heat exchanger where it is liquefied. The liquefied Freon is collected in the final collection tank.
