DEVICE AND METHOD FOR REFRIGERANT LEAK SEALANT ADDITIVE DETECTION |
摘要 |
A device and method for determining the presence or absence of refrigerant leak sealant within the refrigerant charge of air conditioning systems or stores are described. A sensing unit having a seal-forming surface is wetted and placed in fluid communication with a refrigerant access port of the air conditioning system. A depressor opens the refrigerant port and refrigerant begins to flow through the sensing unit. If any leak sealant is present in the refrigerant charge, a sealant plug begins to form on the seal-forming surface and reduces the flow rate of the refrigerant through the sensing unit, thereby indicating the presence of the sealant. Refrigerant charges that do not contain a leak sealant will flow through the sensing unit at a substantially constant rate, indicating the absence of sealant. |
