STEAM 135 - VRF

Credits 1
Variable Refrigerant Flow systems are being installed in residential and commercial structures for space heating and cooling, satisfying the need for human comfort. VRF systems utilize the vapor compression refrigeration cycle to heat or cool building spaces without the use of ductwork. Students will understand the design, installation, and service of these modern refrigeration systems. This course covers how these ductless systems heat and cool multiple building zones increasing system efficiency, increasing occupant comfort, and lowering construction costs compared to conventional boiler and chiller hydronic systems. Some of the equipment discussed will be the outdoor units, BC controllers, and the many different styles of room heat exchange cassettes.
