HVAC – Hot Water and Ventilation

0.50 Hrs
SKU: RVCT-527

The purpose of heating, ventilation, and air conditioning systems (commonly referred to as HVAC systems) is to provide environments that are comfortable for people and allow equipment to operate safely and reliably. HVAC systems are used in residential, commercial, and industrial facilities. This module contains information on hot water heating systems, air distribution systems, and HVAC control systems.

Frequently Asked Questions

What are the four main components to a hydronic heating system?

The four main parts to a hydronic heating system are: a hot water boiler to supply heat; piping and pumps to distribute heat; radiators and/or convectors to emit heat; and control equipment to control water and room temperatures.

What variables do automatic control systems control?

Automatic control sysems used by HVAC systems control: temperature, humidity, pressure, and ventilation (or air distribution).

What are the three safety devices are typically seen with a hot water boiler?

Hot water boilers are typically equipped with safety relief valve to prevent over-pressurization, low-water cutoff to shut off fuel to the boiler on low water, and water-gauge glass to verify the water level.

Why are filters used in HVAC systems?

Filters are used in HVAC systems to remove particulate contaminants from the air stream in distribution ducts.

Sample Video Transcript

All air systems can be single duct or dual duct. Single duct systems provide cooling and heating using the same duct, but cannot provide them simultaneously. Dual duct and multi-zone systems can provide heating and cooling simultaneously. A dual duct system employs two air ducts, a cold air duct and a warm air duct, which run parallel to each other. In an air water system, both air and water are used for temperature control in the condition to spaces. The air and water are cooled or heated in a central plant. The air supplied is called primary air, and the water is called secondary water. Ducting systems with fans distribute the air and water pipelines, and pumps distribute the water.
