Course Description

This course provides an overview of variable refrigerant flow (VRF) technology, including equipment and system types, heating/cooling operation, heat recovery, and the benefits of VRF systems. Also described is the VRF design process, including load profile analysis, unit sizing, ventilation air strategy, refrigerant piping design, and system monitoring/controls. Refrigerant safety considerations are explained, including a discussion of ASHRAE Standards 15 and 34. The course concludes with a focus on human comfort and sustainable design featuring example buildings, ventilation systems, and VRF system layouts.
