Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows a flowchart of a method according to the present invention.

(2) FIG. 2 shows a schematic diagram of the refrigeration system, after an HCFC refrigerant is removed, and while an HFC refrigerant and POE lubricant is being charged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(3) FIG. 1 shows a flowchart of a method according to the present invention. A refrigerant retrofit kit is provided, having within a transportable container, a mixture of a refrigerant and a compatible POE lubricant. The refrigerant is typically an HFC refrigerant. The HCFC refrigerant is evacuated from a refrigeration system to be retrofit, and a portion of the existing lubricant, which is a mineral oil or alkyl benzene lubricant, is removed through the charge port of the refrigeration system, without disassembly of the system. A portion of the mineral oil or alkyl benzene lubricant remains in the refrigeration system. The refrigeration system is then charged with the mixture of the refrigerant and the compatible POE lubricant through the charge port.

(4) As shown in the schematic representation in FIG. 2, the refrigeration system includes a compressor, condenser and evaporator, as well as a charge port. A reservoir pools liquid refrigerant, as well as lubricants found within the system. After the HCFC refrigerant is removed from the system, a portion of the mineral oil or alkyl benzene lubricant remains in the system. During charging, the new refrigerant, typically an HFC, with a compatible POE lubricant, is drawn into the refrigeration system through the charge port, resulting in a mixed lubricant containing mineral oil or alkyl benzene lubricant and POE.

Example 1

(5) A test was conducted of a residential air conditioning unit to determine the results of retrofitting an R-22 system with R-407C. In the test, the R-22 system, which was design and manufactured optimally for R-22, and used a mineral oil lubricant, was retrofitted with R-407C.

(6) Instead of removing all of the mineral oil in the system, and replacing it with a defined amount of POE oil, which is required for R-407C, the R-22 was removed, and the residual mineral oil allowed to remain.

(7) The evacuated system was recharged with a premixed quantity of R-407C with 8% by weight POE oil. Since R-407C is charged in the liquid phase, all of the oil, and most of the R-407C was transferred to the system from a transport container, e.g., DOT-39. The final POE concentration is estimated at 10-15% of the total oil in the system.

(8) Prior to retrofitting, system was run for 13 hours over two days with the R-22 to collect the baseline data. The R-22 was then evacuated, and charged with R-407C to about 85% of the R-22 charge. The retrofitted refrigeration system with R-407C was then run for 91 hours.

(9) The operating temperatures for R-22 (>86F and <86F) and R-407C (<86F) were not the same, so performance measurements are not directly comparable, but the results support a conclusion that the R-407C does not degrade system efficiency performance.

(10) Therefore, despite the various unknowns, including the amount of mineral oil remaining in the system, migration characteristics of the mixed lubricants around the system, the impact of the various lubricant phases on compressor lubrication, the operation of the system with R-407C was improved over the R-22 implementation.
