What are the three types of electrical diagrams used in the heating, cooling, and refrigeration industry?

To determine

The three types of electrical diagrams used in heating, cooling, and refrigeration industry.

Explanation of Solution

The three types of electrical diagrams used in heating, cooling and refrigeration industry are as follows:

1. 1. Schematic diagrams: Schematic diagrams are the diagrams having symbols of electrical components and lines to represent wiring and these are also known as circuit diagrams. They represent the connection of the electrical objects in a circuit that helps to find an error in a circuit so that it can be rectify before manufacturing it.
2. 2. Pictorial diagrams: Pictorial diagrams are also similar to schematic diagrams. They differ by the presentation of electrical objects in the circuit. In pictorial diagrams, the electrical objects are represented by the actual picture of the electrical objects. These diagrams are easy to understand because of the picture presentation of objects.
3. 3. Installation diagrams: Installation diagrams are also called as wire diagrams. The wires are represented by the different colors and sizes so that the installer easily understands the connections. These diagrams also give the information about the arrangement of the devices and their relative positions.
