Heating, Ventilation and Air Conditioning (HVAC) or HVAC&R or HVACR is a technology designed especially for indoor and vehicular environmental comfort. The main purpose of this system is to give warm solace and worthy indoor air quality. HVAC system controls the ambient environment like temperate, air flow, humidity and air filtering. It must be planned and operated along with other components which include as cabling, computing hardware, data storage, physical security, fire protection and power.

HVAC systems are a necessary part of residential buildings such as family homes, hotels, offices, hospitals, ships, submarines and in marine environments where protected and solid building conditions are managed as for temperature and dampness, utilizing natural air from outside.

Types of HVAC systems:

Single stage:

Single-stage warming and cooling is prevalent in colder winter atmospheres and hot and moist zones, deferentially, on the grounds that the frameworks are set to give solace to the coldest or hottest days of the year. In any case, that additionally implies that an awesome dominant part of the time, these warming frameworks or ventilation systems are working at full limit when they don’t should be.

Zoned systems:

Zoned HVAC frameworks can warmth or cool individual zones of your home by controlling zone valves or zone dampers inside the vents or ventilation work, which specifically hinder the stream of air. Zoned systems can spare your energy and money by just warming or cooling certain regions when you require it.

Humidity control:

Humidifiers and dehumidifiers can be added as alternatives to warming and cooling frameworks, and on the off chance that you live in an exceptionally dry or muggy atmosphere these updates should be on your rundown. Around 50 percent relative humidity viewed as ideal for people.

With these systems you can automatically control the humidity levels in your home. With stickiness/dehumidification systems incorporated with your heater or aerating and cooling, you can’t control the moistness levels when the framework isn’t on.

Heating systems:

Heating systems can be classified into furnaces that give warmed air through ventilation work, which is a well-known sort of warming system in the United States such as, boilers that warmth water for steam radiators or constrained water frameworks with baseboard radiators, electric warmth and warmth pumps. Heaters for the most part utilize gaseous petrol or propane for fuel, while boilers can utilize gas or oil.

Cooling systems:

Cooling systems today come in a few unique sizes and types, and what you choose to include or redesign in your home relies upon the systems you as of now have, and also the atmosphere. Proper sizing is vital for effective ventilating. A greater unit isn’t really better in light of the fact that a unit that is too huge won’t cool a zone consistently. A little unit running for an expanded period works all the more productively and is more compelling at dehumidifying than a huge unit that cycles on and off too often.
