HVAC-R stands for heating, ventilation, air conditioning and refrigeration. The main purpose of an HVAC-R system is to provide thermal comfort and reasonable air quality in indoor environments. Implementing such a system is needed so that people can comfortably stay in a closed environment and for perishable goods to be preserved. Simply said, HVAC-R is the process of adding or removing heat, filtering and changing the air, humidifying or dehumidifying a closed room.
Who uses HVAC-R systems?
HVAC-R systems are used inside homes by individuals and also by businesses in their workspace. Homes can either implement their own system or if they are inside a building (and if the building provides such a system) they can use the system that is already implemented. However, some businesses must have an HVAC-R system installed so they can make the environment a more pleasant place for people to be in. They have to have temperature control for both the people that are inside it and also the products that need temperature regulations if they have any. Businesses also have to implement such a system if they want to avoid having any legal issues by not having one, and will have to also go through frequent R22 replacements at http://www.bluonenergy.com/r22-replacement/.
What does HVAC-R mean?
The first part of an HVAC/R system is heating. Of course, the room has to be warm enough so people can comfortably stay inside it. There are different types of heating appliances that can be used to raise the temperature of a closed investment. This can be done via central heating or systems that offer a similar effect.
The second part of the HVAC/R system is ventilation. The ventilation system is responsible for the quaily of the air in the room. Since it is a closed investment, such a system must be implemented for fresh air to enter the room. A building can be ventilated using two methods: through natural ventilation or through mechanical/forced ventilation systems. Mechanical or forced ventilation systems use fans to circulate the air inside the room. On the other hand, natural ventilation systems don’t use any kind of fans. Rather, they change the air in
the room by using windows, louvers, or trickle vents. Placing a natural ventilation system is more energy efficient, however, it can’t be implemented in a lot of closed environments because of the outside temperature and other factors.
The third part of the HVAC/R system is air-conditioning. Just like the heating system is needed to warm up the space when the outside temperatures are low, having an air-conditioning system is necessary for cooling down the room when the room temperatures are too high. If the room
temperature is to high, it will be hard for people to comfortably stay in that room.
While HVAC is used to bring comfort to the people that are using the space, the refrigeration system is implemented to preserve perishable goods such as dairy, meat, fruits, vegetables, flowers etc. These systems are commonly found in stores, supermarkets, factories and they must be implemented by certain businesses.
Lastly, the people that implement and maintain HVAC-R systems are called HVAC-R technicians. These people are trained and licensed to handle and maintain HVAC-R and they are responsible for the quality of the system.
