HVAC Chiller Systems Control
Course Description
A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required. As a necessary byproduct, refrigeration creates waste heat that must be exhausted to ambient or, for greater efficiency, recovered for heating purposes. Concerns in design and selection of chillers include performance, efficiency, maintenance and product life cycle environmental impact. A chiller can be generally classified as a refrigeration system that uses either a vapor compression or absorption cycle to cool. Both the absorption and the mechanical compression systems have the evaporation and condensation of a refrigerant in common. In both systems, the refrigerant evaporates at low pressure to absorb heat and then condenses at higher pressure to reject heat to the atmosphere. Both systems require energy to raise the temperature of the refrigerant for the heat rejection process. Heating, ventilation, and air conditioning – HVAC – chillers are industrial and commercial grade refrigerating systems used in cooling applications (i.e. buildings, raw materials, chemicals, medical equipment and industrial equipment). The system includes a compressor, evaporator, condenser, reservoir, and thermal expansion valve and stabilization assembly. HVAC chillers use water, oils and other liquid compounds as refrigerants. This course is an overview of heating, ventilation and air conditioning (HVAC), including basic design, equipment characteristics, venting, the refrigeration cycle, system control, basic heat transfer, basic airflow principles, air quality, product quality and comfort principles.
