Chadwell Supply. 8 Tips on Refrigerant Recovery

It’s no secret that refrigerant is expensive and you are busy! Being able to safely recover refrigerant to reuse it on your property is important, but also recovering it as quickly as possible is helpful too. Use these eight tips to help you in the process of recovering, recycling and reclaiming refrigerant.

1. NEVER Exceed Refrigerant Recovery Tank Limits

By law, a tank can only be filled to 80% capacity and must be kept under 122°F.

It is recommended to fill to 2 lbs less than the 80%. For example, a 30 lb cylinder can hold 22 lbs of refrigerant and a 50 lb cylinder can hold 38 lbs of refrigerant.

You must calculate to make sure the recovery tank will safely accept the amount of refrigerant being added:

Find the current amount of refrigerant in tank (A). Weigh the recovery tank on a refrigerant scale. Subtract the tare weight (stamped on tank’s side).

Find the amount of refrigerant in the unit by checking the unit’s faceplate (B)

Add the current refrigerant amount from the tank (A) and the amount of refrigerant in the unit (B).

If the result is less than the 80% requirement, then there is enough space for the refrigerant. If the result is more, then an additional cylinder is needed.

(Note: if the tank is empty, the scale should match the tare weight stamped onto the side of the cylinder.)

Safe Refrigerant Recovery

When servicing equipment, refrigerant recovery is a legal requirement. It has been a mandated part of the servicing process since 1993. However, we still receive a number of questions, which raise our concern for the safety of service technicians when performing this essential function. Therefore, we thought it timely to provide some tips that can help you recover refrigerants safely and avoid possible personal injury or damage to your equipment. Many of these recommendations are the same as for handling refrigerants in their original container.

SAFETY RECOMMENDATIONS

• Use personal protective equipment including safety glasses with side shields, gloves, and safety shoes when filling and handling recovery containers. Use a hard hat if required for the work area.

• Avoid skin contact with liquid refrigerant because it can cause frostbite.

• Because refrigerant vapor is heavier than air, it will concentrate in low areas. Avoid these areas unless proper ventilation is provided.

• Avoid inhalation of refrigerant vapor. Be aware that inhalation of high concentrations of refrigerant vapor is harmful and may cause heart irregularities, unconsciousness, or death.

• Recovered refrigerant will typically contain some amount of oil, which can appear as a white cloud or fog. Do not breathe oil mist if it should be emitted during the recovery process.

• Exercise caution when moving filled recovery containers.

• It is recommended that all service technicians periodically review the product MSDS to be reminded of important safety information.

Some additional recommendations apply specifically to the recovery process and recovery cylinders:

• Prior to filling, inspect the recovery container and valve for signs of damage, such as dents or corrosion. Do not fill a damaged recovery container.

• Make sure the cylinder is properly labeled with the type of refrigerant.

• Do not mix refrigerants in the recovery cylinder.

• Ensure that the recovery equipment, recovery cylinder and hoses are rated for the refrigerant you are recovering; check with your equipment supplier.

• Do not overfill the container.

• Recovery cylinders should not be filled if the present date is more than five years past the test date that is stamped on the shoulder of the cylinder.

CYLINDER SELECTION AND HANDLING

Due to their higher pressure, R-410A and R-402A (HP-80) must be recovered in a 4BA400 or 4BW400 high-pressure recovery cylinder. Some refrigerants like R-422A, R-422D, R-407C, R-404A, R-408A, and R-507 can be recovered in a standard 4BA300 or 4BW300 recovery cylinder; however, these same refrigerants must be recovered in a high-pressure 4BW400 half-ton recovery tank since the lower pressure half tons are only rated for 260 psig. For recommended recovery cylinders by refrigerant, please consult the manufacturer/refrigerant supplier.

Do not overfill the cylinder. Liquid refrigerant will expand as its temperature is increased. If the cylinder somehow becomes completely full of liquid, the pressure can increase dramatically with a relatively small increase in temperature.

Refrigerant manufacturers and others who fill cylinders have to know how much refrigerant to put in the cylinders so as not to become liquid full under normal storage/use temperatures, and even at temperatures that far exceed these normal conditions. Now that recovery of used refrigerant is becoming a common practice, contractors and service technicians also need to understand this.

Typically, the cylinder should not be filled to more than 80 percent liquid full at 77°F. Another guideline is to not exceed the gross weight (total weight of the container and its contents). Check with your refrigerant supplier or reclaim provider for specific recommendations.

Most people in the HVACR industry who routinely handle refrigerant cylinders understand the concept of “saturation pressure vs. temperature.”

When there is some amount of liquid refrigerant in a cylinder, the pressure associated with a given temperature will be the saturation pressure. This is the information that is provided in pocket P-T charts that are commonly used in the industry.

If there is only refrigerant vapor in the cylinder, then the vapor is described as a “superheated vapor” and the pressure associated with a given temperature does not follow the standard P-T curves.

If the cylinder somehow becomes completely full of liquid, then other pressure-temperature relationships take over and there is the possibility of an unsafe situation. In a “liquid full condition” the pressure in the cylinder can increase very rapidly with relatively minor increases in the temperature. The design pressure of the cylinder can be exceeded and the cylinder relief valve could begin to vent the high-pressure refrigerant. In a worst-case scenario, the cylinder could burst, causing property damage or personal injury. Table 1 shows pressure-rating data for two commonly used recovery cylinders.

R-22 COMPARISONS WITH R-410A

To demonstrate the effect of temperature and pressure, a series of calculations were conducted on R-22 and R-410A. Fig. 1 assumes that a recovery cylinder, filled with R-22, was properly filled to a safe liquid level of 80 percent at 80°. As the temperature increases, the liquid refrigerant expands inside the cylinder, but the pressure will still follow the saturated P-T curve until it becomes liquid full at 145°.

At this point the pressure begins to increase rapidly with increasing temperature. In most normal situations, a cylinder would not reach this temperature unless it is in a fire or stored in a location subject to very high heat loads. The minimum relief valve setting for a DOT-4BA300 cylinder will be exceeded if the cylinder reaches 145°.

Fig. 2 shows the same information as Fig. 1, but with additional information on R-410A. It is interesting to note that R-410A starts out at a higher pressure, but does not increase as rapidly in pressure as R-22 when the cylinder becomes liquid full at 145°.

Fig. 3 shows R-22 with two additional curves. These two curves assume the cylinders are improperly overfilled to 90 percent and 95 percent liquid level at 80°.

As indicated in the graph, these two cylinders would become liquid full at a much lower temperature (about 130° and 105° respectively). In these two situations, it is much more likely that the relief valve would be activated, especially for the cylinder that was improperly overfilled to 95 percent liquid full. It is also possible the cylinder burst pressure could be exceeded.

The relief valve is designed to prevent this from happening. But in an extreme case, such as a fire, the capacity of the relief valve could be exceeded.

Note: R-22 was used as an example because it is broadly used and familiar to most in the HVACR industry. Most other commonly used refrigerants would exhibit very similar behavior under similar conditions.

BOTTOM LINE

When recovering used refrigerant, follow the recommended practices summarized above. Thoroughly inspect the cylinder you will use and ensure it is designed to handle the pressure of the refrigerant being recovered. EPA has also established under Section 608 that refrigerant recovered and/or recycled can be returned to the same system or other systems owned by the same person without restriction.

If refrigerant changes ownership, however, that refrigerant must be reclaimed (i.e., cleaned to the ARI 700-1993 standard of purity and chemically analyzed to verify that it meets this standard) at an EPA-certified reclamation facility. Remember that R-410A re- quires a DOT-4BA400 or 4BW400 recovery cylinder. Never overfill the recovery cylinder.

DuPont offers reclaim services to its distributors for all of its refrigerants and is available to assist with questions regarding your recovery needs. Further information can be obtained at www.refrigerants.dupont.com or 800-235-7882.

Examining Recovery Cylinder Capabilities

Working with refrigerant recovery cylinders is a basic part of servicing refrigeration systems. Technicians need to work safely when handling these cylinders.

Overfilling these cylinders can create a potential hazard. To prevent overfilling, recovery cylinders should not be filled to more than 80 percent of their internal volume. Most technicians accomplish this by placing the recovery cylinders on an electronic scale and monitoring the weight of the cylinder during the recovery process. When the cylinder reaches a weight equal to 80 percent of its total capacity, the technician stops the recovery process and changes cylinders if needed.

In order to use this method effectively, a technician must know the cylinder’s weight equal to 80 percent of its maximum capacity. This maximum weight will vary slightly as different refrigerants are used in recovery cylinders and different refrigerants have different liquid densities.

MAXIMUM WEIGHT

There are two basic ways to accurately determine the maximum weight of a recovery cylinder:

1. Find the recovery cylinder manufacturer’s published data for various refrigerants.

2. Calculate this value.

To determine this value, use the following procedure:

1. Calculate the internal volume of the recovery cylinder being used. This can be accomplished by dividing the water capacity of the cylinder by the density of water, which is 62.5 pounds/cubic foot. The water capacity of a recovery cylinder normally is stamped on the outside of the cylinder. For example, if a recovery cylinder has a water capacity of 47.17 pounds, then its internal volume will be 0.75 cubic feet (47.17 pounds ÷ 62.5 pounds/cubic foot = 0.75 cubic feet).

2. For the refrigerant to be recovered, determine its liquid density at a saturation temperature of 130°F. Refrigerant manufacturers publish the various saturation properties of their refrigerants, including liquid density at various saturation temperatures. For example, if R-134a were to be recovered, its liquid density at a 130° saturation temperature is 67.46 pounds/cubic foot.

3. Determine the tare weight of the recovery cylinder, which is the weight of the cylinder if it were empty. This is also stamped on the outside of the cylinder. For example, for a nominal 50-pound recovery cylinder, the tare weight would be 24 pounds.

4. Use the following formula to determine the maximum cylinder weight:

Maximum cylinder weight = (cylinder volume x liquid density of the refrigerant at 130°F x 0.80) + tare weight

For example, if the cylinder is holding R-134a, (with its liquid density of 67.46 pounds/cubic foot at 130° saturation temperature) had a water capacity of 47.17 pounds and a tare weight of 24 pounds, the maximum cylinder weight would be:

Cylinder volume = water capacity ÷ density of water (62.5 pounds/cubic foot)

Cylinder volume = 47.17 pounds ÷ 62.5 pounds/cubic foot = 0.75cubic feet

Maximum cylinder weight = (0.75 cubic feet x 67. pounds/cubic foot x 0.80) + 24 pounds = 64.48 pounds.

A technician should not continue to fill this recovery cylinder once its weight has exceeded 64.48 pounds. Again, overfilling a recovering cylinder can lead to very serious injury.
