UNDERSTANDING ELECTRICAL SCHEMATICS Part 1 (Revised
In electrical schematics, the symbols stand for various components in the circuit, and the lines stand for the wires connecting them. The intention of the overall schematic is to show how the circuit functions, not how it actually looks. 1 Refrigeration Service Engineers Society 1666 Rand Road Des Plaines, Illinois 60016 UNDERSTANDING ELECTRICAL SCHEMATICS[PDF]
Basic Electrical Engineering for HVAC Engineers
BASIC ELECTRICAL ENGINEERING FOR HVAC ENGINEERS A heating, ventilating and air-conditioning (HVAC) system is a simple system of heating and cooling exchangers using water or refrigerant (direct expansion system) as the medium. Pumps move the heated or cooled water to the exchangers. Fans then move the warmed or cooled air[PDF]

Electrical Controls - Refrigeration Basics
An HVAC system is designed to combust fuels or consume electrical energy to provide heating or cooling to a conditioned space. These systems must be controlled and made safe. Operating controls sense temperature and signal the system to operate or shut off and rest.

HVAC and Electrical Fundamentals | Heating and Cooling
HVAC and Electrical Fundamentals - Electrical Flow Electricity is delivered to its destination via wires (conductors) or in electronics, semiconductors. Electricity is a series of electrons moving through the conductor or semiconductor at a specific potential or pressure which is referred to as voltage or electro-motive force.
