SUMMARY:Residential Heat Pump Installation and Commissioning for Installers\, Raters and Commissioning Agents (Part 1 of 2)
DESCRIPTION:Part one of this series will start by covering best practices for line set testing\, addressing refrigerant leaks and refrigerant line insulation. This session will focus on how efficient heat pump output relies on both refrigerant charge and total system airflow including: improving the airflow in existing systems\, measuring and estimating airflow\, and adjusting the airflow settings on various types of equipment. \nAgenda: \n\nIntroductions and safety message\nLine set testing using high pressure nitrogen\nLine set testing and cleaning using a vacuum pump\nFinding and repairing leaks in refrigerant lines\nRefrigerant line insulation\nThe interrelated nature of refrigerant volume and airflow volume\nAirflow and heat pump performance\nTargets for system airflow per ton\nWhere are the system airflow settings found\nCommunicating controls vs legacy controls\nHow do you verify that the air handler is operating the way you set it\nHow to measure air flow\nHow to measure static pressure\nHow to measure air handler power\nHow to interpret static pressure and power\nMost common install mistakes that cause low airflow systems\nMost cost-effective ways to raise system airflow\nCommissioning advantages multi stage equipment\nSummary and Q&A\n\nThe objective of this course is that at the conclusion\, participants will be able to: \n\nDescribe techniques for effectively testing line sets\nVerbalize pressure and vacuum targets for line set testing\nIdentify how efficient heat pump output relies on both refrigerant charge and total system airflow\nPresent strategies for improving the airflow in existing systems\nName techniques for measuring and estimating airflow\nDescribe how to change the airflow settings on various types of equipment
