Free Chiller Service Course: https://chilleracademy.com/p/free-chiller-training UPDATE: I made a mistake on my YVAA rundown. There is not a drain valve after the flash tank. It uses the "condenser drain valve" aka the feed valve only. In this hvac training I explain the refrigeration cycle of a York chiller. YCIV & YVAA are great hvac system for any building air conditioner. This hvac training videos goal is to help hvac technician better understanding these AC systems. 00:00 Intro 00:24 Visual Explanation 05:56 Main Panel Readings Explanation 09:38 YCIV Drawing Explanation 20:38 Evaporator Design Changes 22:38 YVAA Drawing Explanation 28:44 Closing & Tech Support
