HVAC Units – Various components to know

Before looking into the list of HVAC units, you must first understand what HVAC really is. HVAC units perform three main functions- ventilation, heating, and air conditioning. These functions are put together for forming a single system and are made in such a way that they go with contemporary construction requirements for a house or office.

They are attributed specifically for the dehumidification and cooling of specific systems. Of all the HVAC systems, the most popular is the central HVAC as they are quiet and convenient.

HVAC units have evolved in time and they have come a long way in modernization. One of the most common issues linked with conventional systems was the cost. But, due to the formulation of cost-effective solutions more homes and establishments are enjoying such machines. Here is a list of products under HVAC systems.

HVAC blowers and fans

HVAC blowers and fans are utilized in the movement of air. They are extremely important in air handling systems because they help in bringing in fresh air inside different constructions. They can be mounted above a ceiling or an outer wall. In certain cases, they may even be utilized as a component of duct fun. Some very common products that lie within this category are plenum fans, ventilation fans, roof fans, inline fans, duct blowers, vane axial fans and centrifugal blowers.

Heat Exchanger

A heat exchanger is essentially the furnace housing and helps to warm up cool air as well as absorb heat. When the thermostat turns on the furnace, the combustion leads to production of heat. Furnaces of all kinds possess heat exchangers. This significant component comes with strong temperature-resistant stainless steel, to prevent damage. Some of the models also have special ducts for letting cool air come into the heat exchanger quickly.

Blower Motor

Once the air inside the heat exchanger goes up to a preset temperature, a fan is powered by an electric blower motor forcing the warm air inside the ductwork of a house, with the help of air registers, and inside every room within the house. Before the blower motor halts, combustion ends making warm air travel to the rooms.

Motors with variable speeds can run at various speeds to control the airflow precisely in the house. It helps in monitoring the HVAC and helps in compensating for numerous problems. As blower motors with variable speeds reach full speed very gradually, they can reduce humidity effectively during summer months. Houses often get to the right temperature before the speed units attain full speed. Hence, they help save energy.

Thermostat

Thermostats come with temperature sensors that help to decide when the air conditioner and heater will turn off and on. It has a direct connection with the system with special wires. One of the best areas to place a thermostat is close to the middle of the house, further from drafts. Few of the air conditioning and heating systems come with more than a single thermostat, and every thermostat helps in controlling a different zone.

HVAC is an important part of our lives and helps in keeping the air quality comfortable. However, you must also contact an HVAC expert in case of a fault or when you decide to buy a new system.
