| Description: | Engineering Pathway's "Today in History" for February 12. "Today in History - February 21, 1994 - Whirlpool begins production of refrigerators without freon.. In the 1930s, refrigerators began to use freon as a refrigerant. However, the use of freon became an environmental concern once it was identified as a ozone-depleting chemical. Fortunately, household appliance manufacturers have since switched to a different refrigerant, HFC-134a, which has no ozone depleting properties." |
