EVERYTHING YOU SHOULD KNOW ABOUT HVAC

HVAC

stands for heating ventilation and air conditioning

HVAC is basically a tools which implements the process of heating,ventilation and air conditioning which we will understand in details.

If you don`t know what is hvac so stay tune till the end of article.

well this articles may solve your queries related to hvac and will give brief explanation of what exactly is hvac.

so lets break this curiosity of Do you know what is hvac?

There are many question which arise in the minds in this field of hvac ,so here it is and also answers of it

HVAC COMFORTABLE TEMPERATURE

HAVE YOU EVER THOUGHT HOW WE MANAGE TO MAINTAIN COMFORTABLE TEMPERATURE ?

COMFORT TEMPERATURE

If NO , then this is the right platform to dig out your curiosity.

wait! wait! do you know what is HVAC comfortable temperature?

Okay let’s understand it properly.

It is a temperature in which the human body feels comfortable to carry out their daily schedules.

ASHRAE STANDARDS

HVAC ASHRAE DETAILS

Winter std temp :72°f

Summer std temp:76°f

HVAC ASHRAE: AMERICAN SOCIETY OF HEATING REFRIGERATION AND AIR CONDITIONING ENGG.

ASHRAE society which works on the betterment of comfort temperature having group of people with high experience.

Hope! you got what is comfort temperature.

Lets jump on how to develop and maintain comfortable temperature!

For that we need to understand the behaviour of atmospheric air.

Basically, we live in an environment where air is the mixture of dry air and water vapour which is called as moist air.

In order to maintain the temperature suitable for us one must understand the trade of moist air behaviour.

Have ever come across sweating in hot summer and sweat less in winter?

So, lets discover it today before understanding HVAC!

As I said air is mixture of:

· Dry Air (HVAC)

· Water vapour (HVAC)

So, by studying this factor we will understand the secret. In winter the amount of water vapour present in the environment is low than that of the dry air. So it absorbs the sweatiness rapidly

while in summer it is exactly opposite to winter, that the amount of water vapour present is high (generally due to hot sun closer to earth) than that of dry air. so in summer it gives heat but avoids absorbing the sweat than is why we sweat a lot than that of winter.

I hope we are clear with this.

So after studying this we can use our tools to generate and maintain HVAC comfortable temperature.

And the tools to do it is HVAC.

WHAT HVAC?

YES HVAC , well you heard right ! HVAC is the abbreviation for:

HEATING

VENTILATION

AIR CONDITIONING

Basically, this are some process through which we can maintain comfortable temperature.

So lets explore this HVAC process for better understanding!

• HEATING is the process of adding heat, if the temp is less than the std temp , by using electrical resistance heater.

• VENTILATION is a process in which fresh air is been provided in an space in order to maintain sufficient amount of oxygen and foul gases are been exhausted out through fans

• AIR CONDITIONING is the process in which air is been conditioned according to human comfort with thermal gadgets.

So the ultimate goal is to maintain std temperature in which human being feels comfortable using this tools of hvac in the form of equipment.

This is all through which we can controls HVAC requirement

• Std temperature

• Motion cleanliness

• Distribution of air

Noise level

Which helps to provide HVAC comfortableness to human

hope we get it what is HVAC AND HVAC COMFORTABLE TEMPERATURE.

With this process, it not only generates HVAC COMFORTABLE TEMPERATURE but also generate revenue to a country

Yes! you heard right my friends

Confused?

Let’s flush off your confusion.

Basically, the revenue of the country is mostly dependent on working people in offices and business houses which work effectively and efficiently due which generates revenue.

Ever thought how they can work effectively and efficiently? Did somethings struck in your minds!

Okay let me give you an example, consider you are student preparing for your exams in a room without comfortable temperature will you be able to focus on studies more effectively and efficiently

Well I hope you got your answer!

Now comes the question who is responsible to maintain comfort temperature?

Well the answer is HVAC ENGINEER.

HVAC ENGINEER

Hvac engineers calculate, design and execute the programs of maintaining the comfortable temperature by using various equipment which helps in fulfilling the demands of heating, ventilating and air conditioning according to location, space, environment and orientation.

To be more clear he visits the place to conditioned according to human comfort, collects data of space, location, orientation of sun and calculate amount of comfort air required using engineering tools and select equipment to execute the plan to get it done.

To understand in details about it will surely write on this in future.

Now let’s take into consideration some application where HVAC system are been implemented to maintain a comfortable environment in desired space.

It is categorised into two:

• Human comfort

• Processing industry

Well HVAC human comforts are the temperature to be maintain for humans.

Processing is the field of business or industry, where machine produce different variety of productions in different fields like textile, paper, etc where maintaining temperature is important but there are also some other factors which must be taken care of is examined by hvac design.

For example in medical production industry or printing industry we need dehumidifying process( removing water vapour to avoid ink spreading while printing) and also other factor that will discuss further , to maintain smooth finishing of the system and avoid breakdown of machines hence we requires HVAC to control temperature in both sectors and maintain the smooth production and comfortness in the world.

Hence , as discussed, this field of controlling temperature with other factors plays a vital role in the world map and world economics as it directly proportional to the growth and development of a sector directly and indirectly.

Directly by maintaining temperature controls of instrument in industry by avoiding breakdown of machines and production, and indirectly by increasing the efficiency of working of humans with comfort temperature.

So thanks to HVAC engineer for designing and developing such a system .

Well, come to application in both sector:

HVAC Human comfort

RESIDENTIAL

COMMERCIAL OFFICES

HOTELS AND RESTAURANTS

SUPER MARKETS

MALLS

HOSPITALS

HVAC Processing industry

CNC/NC MACHINES
PATHOLOGICAL LAB
OPERATION THEATRES
MRI ROOMS
CLEAN ROOMS
FOOD PROCESSING

This are some example which you will find in your day to day life all around you.This is some kick start for HVAC we will surely meet up with some new article in details regarding heating ventilation and air-conditioning.

Hope,you understood this topic hvac? and Hvac comfortable temperature?
