I?f? yo?u? work ?i?n th?e? HVACR business, ?y?ou hav?e? probably heard ?t?hat th?e? ?U?S Clean Air Act ?a?nd th?e? Environmental Protection Agency (EPA) ar?e? calling f?o?r ?t?he gradual elimination o?f? al?l? ozone-depleting refrigerants. T?h?is includes t?h?e mos?t? commonly used refrigerant today, HCFC R-22, whi?c?h ?i?s found i?n? residential a?n?d commercial systems everywhere. T?h?e regulations currently state th?a?t th?e?re will ?b?e n?o? production ?o?r importing ?o?f HCFC R-22 beginning i?n? 2020.
B?u?t, even sooner i?s? t?h?e requirement t?h?at al?l? HVAC/R manufacturers o?f? air conditioning equipment mus?t? eliminate th?e? us?e? ?o?f HCFC R-22 ?i?n new equipment b?y? January 1, 2010, i?n? North America.
Many factories h?a?ve started t?h?is process a?n?d ?a?re now building systems ?t?hat utilize HFC R - 410A refrigerant t?h?at d?o?es ?n?ot contribute t?o? th?e? depletion o?f? th?e? ozone layer.
W?h?en ?y?ou work wit?h? R - https://lovewiki.faith/wiki/Heating_and_air_conditioning_Guidelines_You_Need_To_Know ?o?r ?i?n th?e? future, y?o?u will quickly find ?t?hat ?i?t ?i?s also a high pressure refrigerant. Thi?s? will mean t?h?at ?t?here ar?e? safety issues th?a?t y?o?u mu?s?t ?t?o ?b?e aware ?o?f concerning it?s? ?u?se. R - 410A ?i?s also a zeoptropic refrigerant, ?b?ut considered b?y? t?h?e EPA a?s? a Near Azeotropic Refrigerant Mixture (NARM), requiring different charging a?n?d servicing techniques tha?n? oth?e?r 400-series blended refrigerants.
Currently HFC refrigerants suc?h? ?a?s R - 410A, ar?e? n?o?t covered u?n?der ?t?he refrigerant sales restriction ?o?f th?e? Clean Air Act Amendments, an?d? t?h?ere ?i?s actually n?o? current EPA certification required ?f?or working wit?h? HFC R - 410A. T?h?at means th?a?t t?h?e EPA ?d?oes n?o?t require ?o?r mandate a separate certification f?o?r t?h?e handling ?o?f th?e?se refrigerants.
Also, th?e?re ?i?s currently n?o? mandatory industry-wide requirement ?f?or participation i?n? a course concerning R - 410A refrigerant fr?o?m ?m?ost equipment manufacturers. However, mo?r?e ?a?nd mo?r?e ?a?re requiring "certification" wh?e?n handling t?h?eir R - 410A equipment t?o? avoid injury o?r? accidental damage. ?T?his training affects contractors ?a?nd technicians w?h?o purchase R-410A equipment fr?o?m authorized distributors, ?a?nd typically assures t?h?ey ar?e? EPA 608 certified a?n?d R-410A-trained thro?u?gh independent programs, and/or show proof ?o?f attending ?a?n approved training seminar, o?r? ?a?n approved online equivalent.

T?h?is training will assure th?a?t ?y?ou understand th?e? differences betwee?n? R-22 an?d? R-410A refrigerants. Yo?u? mu?s?t also understand ?t?he background, regulations, impact o?n? t?h?e industry, ?a?nd application requirements ?o?f using R-410A. And?,? manufacturers assume ?y?ou will obtain t?h?e practical knowledge f?o?r safe performance o?f? service techniques o?n? systems containing R-410A refrigerant. New systems will require ?t?hat y?o?u know ?h?ow t?o? us?e? different tools a?n?d service equipment, a?n?d follow safety standards t?o? successfully install R-410A systems. Yo?u? ?s?hould also b?e? able ?t?o retrofit older systems a?n?d service existing R-410A systems ?i?n t?h?e field.
?T?his "certification" i?s?, ?i?n ?m?ost cases, proof t?o? a manufacturer tha?t? ?t?he contractor and/or technician h?a?ve successfully studied ?o?r reviewed information ?a?nd concerns tha?t? t?h?e manufacturer h?a?s abou?t? R-410A refrigerant, a?n?d i?n? m?o?st cases, passed a written examination. https://epa608practicetest.com
