What is HVAC electrical systems?

Introduction to HVAC The goal for a HVAC (Heating, Ventilation and Air Conditioning) system is to provide proper air flow, heating, and cooling to each room. In this process HVAC systems can provide reduce air infiltration and maintain pressure relationships between spaces.

What are the electrical components of an air conditioning system?

Electrical Components of Air Conditioning System

• Capacitor. The capacitor absorbs and stores electricity from the main supply.
• Contactors.
• Relays.
• Fan Motor.
• Crankcase Heater.
• Thermostat.
• Pressure Switches.
• Electrical Wiring and Cabling.

How do you read HVAC blueprints?

HVAC plans are generally drawn at the same scale as the floor plans. The scale helps to measure the size, length, and distance of the plans. The most common scale is 1⁄4″ = 1′-0″ (1:50 metric) for residential and small commercial projects, and 1⁄8″ = 1′-0″ (1:100 metric) for large commercial projects.

How are wiring diagrams organized?

Unlike a pictorial diagram, a wiring diagram uses abstract or simplified shapes and lines to show components. Pictorial diagrams are often photos with labels or highly-detailed drawings of the physical components.

What is the symbol for supply duct?

An “X” in a square or round shape is indicative of Supply Air, while a single Diagonal line indicates return air. The following symbols indicate the type of air but also that of a riser duct. A riser duct is one that penetrates a floor.

How do I get an electrical wiring diagram for my HVAC system?

Usually, the electrical wiring diagram of any HVAC equipment can be acquired from the manufacturer of this equipment who provides the electrical wiring diagram in the user’s manual (see Fig.1) or sometimes on the equipment itself (see Fig.2). The installation diagram. It is the most common type of wiring Diagrams.

What do the symbols in a wiring diagram mean?

Wiring diagrams use simplified symbols to represent switches, lights, outlets, etc. Here is the wiring symbol legend, which is a detailed documentation of common symbols that are used in wiring diagrams, home wiring plans, and electrical wiring blueprints. Step 1: Launch EdrawMax on your computer.

How do HVAC technicians connect electrical components together?

Connecting all of the electrical components together is the electric wiring. To keep track of wiring, HVAC technicians rely on circuit schematics or visual representations of wiring programs. There are three basic types of circuit schematics used in HVAC today. They are the Line Diagram, the Ladder Diagram, and the Installation Diagram.

What are the different types of wiring diagrams?

The installation diagram. It is the most common type of wiring Diagrams. It is called ladder because the symbols that are used to represent the components in the system have been placed on the rungs of a ladder. ladder diagrams will be referred to as “schematic” diagrams, or simply “schematics.”
