In this module, we will go over AHRI Standard 700 and what it means for us as technicians. Skip to quiz!


1. Air Conditioning, Heating, and Refrigeration Institute

AHRI stands for Air Conditioning, Heating, and Refrigeration Institute.


It is a trade association for the manufacturers of HVAC equipment that develops standards and guidelines for modern industry-accepted practices.


The AHRI sets specific standards for recovering and reclaiming refrigerants. Recall that recovering refers to removing refrigerant from a system and storing it in a separate container.


AHRI is one of two certified organizations by the EPA to set these standards.


2. Reclaiming Refrigerants


Reclaiming refrigerant means to reprocess it. Reprocessing is a set of steps that clean the refrigerant and basically make it new.


You can think of a place that reclaims refrigerants like a dishwasher. A dishwasher goes through cycle that washes your dishes and make them usable again.


It’s the same as reclaiming refrigerant. Reclaiming removes impurities so it’s basically new again.

To reclaim the refrigerant, you must first recover the refrigerant from the appliance. After the refrigerant is recovered, it is then sent to a EPA-certified facility to be reclaimed.


Reprocessed refrigerant must meet the specifications of a ‘new’ refrigerant for resale.


AHRI Standard 700-2016 determines the standard of purity that reclaimed refrigerants must meet. Refrigerant that is ozone depleting has to meet the standards set in AHRI Standard 700-2016 before it can be resold or change ownership.


For example, if you are recover R-22 from a system, you cannot use that R-22 refrigerant in other appliances. The only exception is if you use it in other appliances owned by the same owner.


Otherwise, that recovered R-22 refrigerant needs to be reclaimed to virgin specifications according to AHRI Standard 700, before it can change ownership.


The purity of refrigerants can be verified using analytical test procedures described in the AHRI Standard 700.


3. Conclusion


AHRI is an organization that produces modern guidelines for the HVAC industry. AHRI Standard 700-2016 dictates the specifications of purity that refrigerant must be reclaimed to before being resold.


Question #1: Can refrigerant be resold?

  1. Yes, but only if it has been reclaimed to AHRI Standard 700 specifications

  2. Yes, but only if it has been inspected by the EPA

  3. Yes, all refrigerant can be resold

  4. No

Scroll down for the answer...











In order to be resold, refrigerant has to be reclaimed according to AHRI Standard 700 specifications.


Question #2: If you recover R-12 refrigerant, can you use the recovered refrigerant in another device owned by a different person?

  1. Yes, but only if it has been reclaimed to AHRI Standard 700 specifications

  2. Yes, but only if it has been inspected by the EPA

  3. Yes, all refrigerant can be resold

  4. No

Scroll down for the answer...











Using the refrigerant owned by a different person is considered changing ownership. So, to change ownership, refrigerant has to be reclaimed according to AHRI Standard 700 specifications.
