Abstract
The invention relates to a device for recovering refrigerant, particularly chlorofluorocarbons, from a closed cooling system, comprising a perforator with which a gas-tight connection can be formed with the closed cooling system, a device for separating gaseous components from substances coming from the cooling system, which is characterized by a unit for liquefying the refrigerant and separating gaseous components, particularly air, therefrom.
Claims20
A device for recovering refrigerant from a closed cooling system, comprising:
- a perforator with which a gas-tight connection can be formed with the cooling system;
- means for separating gaseous components from substances coming from the cooling system;
- and
- a unit for liquefying the refrigerant and separating gaseous components therefrom,
- wherein the unit includes a gas conduit which connects onto the gas separating means and which is provided with a compressor which connects onto a tank for liquid refrigerant, a gas discharge of said tank for liquid refrigerant being connected via a cooling unit to a gas outlet of the device for discharging non-condensable gaseous components separated from said liquid refrigerant.
