Refrigerant transfer system and method
A refrigerant recovery/recycling system includes a source container fluidly connected to a recovery/recycling device via a vaporizer. Liquid refrigerant is introduced into the vaporizer via the source container and the vaporizer changes the refrigerant from a liquid into a vapor. In so doing, slow/no flow conditions of both the source container and the recovery/recycling device can be reduced, which increases the rate in which the recovery/recycling device is charged with refrigerant.
1. A refrigerant recovery/recycling system, comprising:
a source container for storing refrigerant;
a recovery/recycling device having a refrigerant recovery tank;
a vaporizer disposed between and fluidly connected to the source container and the refrigerant recovery tank of the recover/recycling device.
2. The system according to claim 1 , wherein the vaporizer is a thermal expansion valve.
3. The system according to claim 1 , wherein the vaporizer is a regulator.
4. The system according to claim 1 , wherein the vaporizer is a pulsed solenoid.
5. The system according to claim 1 , wherein the vaporizer is an orifice.
6. The system according to claim 1 , wherein the vaporizer is positioned within the recovery/recycling device.
7. The system according to claim 1 , wherein the vaporizer is positioned away from the recovery/recycling device.
8. A method for charging a recovery/recycling device with refrigerant, comprising:
transferring liquid refrigerant from a source container to a vaporizer separate from said source container;
vaporizing the liquid refrigerant using the vaporizer;
transferring the vaporized refrigerant from the vaporizer to a refrigerant recovery tank of the recovery/recycling device.
9. The method according to claim 8 , wherein the vaporizer is a thermal expansion valve.
10. The method according to claim 8 , wherein the vaporizer is a regulator.
11. The method according to claim 8 , wherein the vaporizer is a pulsed solenoid.
12. The method according to claim 8 , wherein the vaporizer is an orifice.
13. The system according to claim 8 , wherein the vaporizer is positioned within the recovery/recycling device.
14. The system according to claim 8 , wherein the vaporizer is positioned away from the recovery/recycling device.
