HVAC

Furnaces are electronic devices that are capable of generating heat in a controlled way using the combustion of a source of fuel. The thermal energy which is then produced is used to provide heating effects to places such as rooms, houses, buildings etc. in industries and commercial areas, different types of furnaces are used because Furnaces they produce heat by processing commercial materials.

Furnaces

In this article we will talk about two types of furnaces-

1. Furnaces used in home and buildings
2. They used in industries for processing metals and other materials.

Furnaces Used In Homes

Furnaces produce heat for homes and buildings by letting heated air pass through ducts that will lead to rooms to warm them. The heat energy required for this is generated by using electricity, combustion of fuels or related means. The following are the methods or fuels which are used for heat energy generation-

• Wood burning
• Waste oil
• Oil fired
• Duel fuel
• Electric
• Gas fired

 Furnaces Used in industries

Furnaces that are used in the industrial areas use fuel or combustion gases to generate heat energy. The material used can be with direct contact with fuel and its gases (called blast furnaces). Can be in indirect contact with the fuel but directly in contact with its gases, such a furnace called a reverberatory, or it can be directly in contact with the fuels as well as the gases, such a furnace is called muffle furnace. No matter what method they use their main goal is to produce heat.

Features Of Furnaces

Heating levels having multi-stage

•  Furnaces having high efficiency consist 2 or more heating levels.

• During cool days, the furnace automatically increases up to high, or full capacity. During the spring season, the furnace mostly works on low settings, which is giving out warm air for a longer time.
• Benefit: The exchanger of heat and ductwork has the capacity of staying warmer longer, which is more energy saving than again and again turning the burner on and off.

Variable speed blower motors

• A blower is responsible for the controlling air circulation. The blower motor has different speed and has variable fan blower speed that enables it to make automatic adjustments to adapt to heating and cooling demands.
• Benefit: A blower motor having variable speed consumes almost as less as 75% to 60% less power, and is long lasting than conventional blowing motors, and makes less noise as compared to standard blowers.

HVAC is abbreviated as Heating, Ventilating and Air-Conditioning. HVAC system provides a good and comfortable environment for the indoors. It ensures a safe air quality and thermal comfort for the humans.

HVAC System

This system has been designed to improve the environment of indoor. HVAC system is used in every indoor, be it commercial or residential building. It provides both heating and cooling effect in indoor as per condition. HVAC system focuses to use outdoor fresh air to provide improved air quality to indoor. This system has been very popular in different buildings for providing cozy indoor environment.

HVAC system aims to provide a toxic free environment by removing harmful gases, bacteria, dust etc. It controls the humidity levels and temperature as per the condition. It also removes excess carbon dioxide from the indoor.

What does HVAC system comprise of?

 HVAC system provides heating, ventilation and air-conditioning properties. It helps to ensure a safe environment for the humans. All the three properties are very essential for good indoor environment.

Heating – heating is used in the system to heat the air present in the indoor. HVAC system provides a warm and serene condition. This system consists of boiler and furnace to heat and steam water. The heat is transferred through pipe system it is done by using radiators.

Ventilation – ventilation basically refers to movement of air in and out. HVAC system provides a mechanical operation to circulate air in and out. By this system air gets filtered ensuring all the contaminants and moisture is removed. Ventilation helps in replenish oxygen.

Air-Conditioning – HVAC system includes air conditioning, this helps in removing heat from the indoor. Air conditioner controls the humidity of the space and provides a cozy environment.

How Does a HVAC System Work?

HVAC system is primarily based on thermodynamics, fluid mechanics and heat transfer. These principles control the whole HVAC system. This system is used to provide heating and cooling properties to your indoor. It used in every indoor like homes, building, hotels, school, hospital etc.

The very basic working of HVAC system firstly involves intake of outdoor air. After collecting the air it gets filtered by using filters. The filtered air then moved through cooling coil which takes out the humidity from the air.

Next, it is then supplied through the duct to the air handling unit for the further filtration process. After the filtration it is supplied to the respective space. It is supplied according to the required temperature and humidity in the room.

Different Parts Of HVAC System

There are different parts of the system which continuously works to provide you a suitable environment.

Air exchange – This system include air exchange part which help in the ventilation process. This part helps to draw air in and out and passes it through a basic filter.

Thermostats – thermostats main function is to control the hot and cold air and provide the required air.

Furnace – furnace in the system used to heat air as needed according to the indoor environment. There are various sources to heat, like electric pumps and solar energy.

Ducts – HVAC system includes channels to pass the air and called ducts. Ducts carry hot and cold air as required.

Condenser – the condenser found in the outdoor. It filled with refrigerant gas. Condenser functions to convert refrigerant gas to a liquid, when it is in cooled form. It then supplied to the evaporator coil.

Coils – the coils help the system to cool the air. It also converts the liquid from the condenser into the gas form.

Blower – blower basically gives the warm air to the indoor through the pipes.

Vents – vents are the most important part, which designed to exchange air in and out from the ducts.

Difference between HVAC and air conditioning

HVAC is heating, ventilation, and air conditioning. So, it is clear that air conditioning is just a unit of HVAC system. Air conditioner used to cool the sorrounding air. But HVAC system used for both cooling and heating purposes.

The basic difference between HVAC system and air conditioner is that, HVAC heat, cool and ventilate. And air-conditioners are able to cool down the space.

Air conditioner primarily works to provide cool air to the indoor. There are two types of air conditioner window units and central Air conditioner. AC can be used with a heat pump to get both heating and cooling.
