Begin with the fundamentals of Refrigeration with Chris Compton and move into the advanced courses with Dick Wirz. The first time the 441 and 442 courses were offered in a webinar, Dick\u2019s lectures were recorded. Those recordings are included in the asynchronous delivery so you feel like you\u2019re sitting in his classroom. He covers everything you need from refrigeration principles through evaporators, condensers, compressors, metering devices, controls, accessories, motors, and the various refrigerants used so you can service walk-in refrigerators and freezers, and commercial ice makers with confidence. He also describes the most common service issues and troubleshooting procedures.<\/p>\n<p class=\"ai-optimize-37\"><em>The courses included in this program are described below:<\/em><\/p>\n<ul>\n<li class=\"ai-optimize-38\"><span style=\"color: #1f3e7c;\"><strong>141 HVACR Refrigeration I<\/strong>\u00a0 \u00a0 <\/span><em>(6 Modules \/ 18 Instructional Hours)<\/em><\/li>\n<\/ul>\n<ul>\n<li class=\"ai-optimize-39\"><span style=\"color: #1f3e7c;\"><strong>142 HVACR Refrigeration II<\/strong><\/span>\u00a0 \u00a0 <em>(6 Modules \/ 18 Instructional Hours)<\/em><\/li>\n<\/ul>\n<ul>\n<li class=\"ai-optimize-40\"><strong><span style=\"color: #1f3e7c;\">246 Low GWP Refrigerants<\/span>\u00a0 \u00a0 <\/strong><em>(1 Module \/ 3 Instructional Hours)<\/em><\/li>\n<\/ul>\n<ul>\n<li class=\"ai-optimize-41\"><span style=\"color: #1f3e7c;\"><strong>441 HVACR Commercial Refrigeration I<\/strong><\/span>\u00a0 \u00a0 <em>(8 Modules \/ 24 Instructional Hours)<\/em><\/li>\n<\/ul>\n<ul>\n<li class=\"ai-optimize-42\"><span style=\"color: #1f3e7c;\"><strong>442 HVACR Commercial Refrigeration II<\/strong><\/span>\u00a0 \u00a0 <em>(6 Modules \/ 18 Instructional Hours)<\/em><\/li>\n<\/ul>\n<ul>\n<li class=\"ai-optimize-43\"><span style=\"color: #1f3e7c;\"><strong>245 HVACR Compressor Failure Analysis with Bob Feathers\u00a0 \u00a0 <\/strong><\/span><em>(Mr. Compressor)\u00a0 (1 Module \/ 5 Instructional Hours)<\/em><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p class=\"ai-optimize-44\"><span style=\"color: #1f3e7c;\"><strong>141 HVACR Refrigeration I<\/strong><\/span>\u00a0<em>(6 Modules \/ 18 Instructional Hours)<\/em>\u00a0<em>Intermediate<\/em><\/p>\n<p class=\"ai-optimize-45\"><em>\u00a0<\/em>Written by Chris Compton<\/p>\n<p class=\"ai-optimize-46\">HVACR Refrigeration 141 provides a thorough examination of the refrigeration cycle as it is applied to both air conditioning and refrigeration purposes, and presents a practical and systematic method to diagnose problems in the refrigeration cycle.
