Methods and containers for transporting, transferring, storing and using refrigerants
A system and method for delivering a refrigerant to a refrigerant system. The system includes a distribution system comprising a distribution vessel, a transfer line, at least one pump, a distribution line and a distribution line branch arranged and disposed to transfer refrigerant from the distribution vessel to the refrigerant system. The system additionally includes a monitoring system comprising one or more sensors arranged and disposed to measure at least one distribution parameter within the distribution system and a recovery system arranged and disposed to selectively receive refrigerant based upon the refrigerant suitability for use in the refrigerant system.
1. A method for delivering an olefinic refrigerant to a refrigerant system, the method comprising:
providing a distribution system arranged and disposed to deliver the olefinic refrigerant to the refrigerant system;
measuring at least one distribution parameter of the olefinic refrigerant with one or more sensors within the distribution system; and
selectively directing the olefinic refrigerant to either the refrigerant system or a recovery system with the distribution system based upon the refrigerant suitability for use in the refrigerant system in response to a comparison of the at least one distribution parameter and at least one threshold parameter,
wherein the selectively directing includes directing the olefinic refrigerant to the recovery system when the at least one distribution parameter exceeds one or more of the following threshold parameters:
a temperature measured with the one or more sensors exceeds a refrigerant temperature of 100° C.; and/or
a non-absorbable gas concentration measured with the one or more sensors exceeds a refrigerant non-absorbable gas concentration of 1.5 volume percent at 25° C., per AHRI 700 (2016).
2. The method of claim 1 , wherein the at least one distribution parameter is selected from the group consisting of refrigerant temperature, refrigerant non-absorbable gas concentration and combinations thereof.
3. The method of claim 1 , wherein the distribution system further includes a distribution vessel, a transfer line, at least one pump, a distribution line and a distribution line branch.
4. The method of claim 3 , wherein the distribution line is configured to mate with the refrigerant system to deliver the refrigerant to the refrigerant system.
5. The method of claim 4 , wherein the one or more sensors are arranged and disposed to measure the at least one distribution parameter at the distribution line branch prior to delivering the refrigerant to the refrigerant system.
6. The method of claim 1 , wherein the recovery system includes a recovery vessel.
7. The method of claim 1 , wherein the non-absorbable gas is oxygen.
