Variable refrigerant flow (VRF) has about 24% of the global commercial air conditioning market, and over 35% market share in China, India, the European Union, and Eastern Europe. The VRF share of the U.S. market is still only about 3%, but multiple manufacturers sell these systems in the U.S. and sales are growing.
This 3-hour course describes how VRF systems operate, as well as why these systems have the potential to provide energy savings over the traditional systems used in U.S. commercial buildings today.
Learning Objectives
Upon completion of this course, participants will be able to:
- Identify major categories of commercial building energy use by appliance.
- Explain how variable refrigerant flow (VRF) systems operate.
- Describe how a heat pump operates.
- Distinguish among different heat pump operating cycles.
- Compare VRF systems with direct expansion (DX) systems.
- Explain the advantages and disadvantages of VRF systems.
- Identify the types of facilities best suited for VRF systems.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. PDH credits are not awarded until the course is completed and quiz is passed.
