HVAC systems: The most important things you need to know about them

 Systems like HVAC can help in Heating, Ventilating, and Air Conditioning. And yes, that’s where the name comes from! These systems (such as air compressors) are great for occupied indoor areas and can help in thermal control for any desired space. In this article I want to talk a bit more about these systems and help you get a better understanding about their functionality, component, maintenance, etc. and will introduce a few useful resources for further reading on each subject. Are you ready? Then keep on reading.

 


How to maximize your HVAC’s efficiency

Each and every system wears out over time and these systems are not an exception. But here I will tell you how to get the most out of your system and also the ways to increase their lifetime!

It’s not a secret that all systems need regular maintenance to keep working the way they’re supposed to. But some people just don’t know how much the right maintenance can affect efficiency and just do some basic steps and checkups on the system. Keep in mind that the HVAC system contains multiple electrical and mechanical components and various connectors to keep them connected. Each and every one of them need maintenance to work the way it should and save you time and energy in the long run. Now, let’s get to the real question:

What are the things you need to consider for HVAC maintenance?

One of the most important things to keep an eye on is the filters (like air filters) used in the system. These filters should be cleaned constantly and replaced at the right time to provide the best performance in the system. Debris and dust in the filters and other parts like blowers should be cleaned and removed from the units since in the long run, they decrease efficiency, lower the air quality, and might as well broke the system completely.

You need to constantly lubricate the moving parts as well. Proper lubrication can prevent excessive heating and keeps them in good shape to work effortlessly.

Another thing to consider in HVAC maintenance is the voltage of electrical components and their electrical connections. If they are not at the right voltage, they can compromise the whole system and you’ll end up spending a lot of money that could’ve been easily avoided at the maintenance stage.

Regular maintenance and calibration of the system are important too. Check to see that the actual outcome matches the reported numbers. Depending on the corresponding part of your system, you might need annual, seasonal, or monthly maintenance to repair the system, inspect different parts for damage and leakage, lubrication, cleaning the system and the filters and so on. If you want to maximize the efficiency, it’s better to set checkups monthly for cleaning and inspection to make sure every part works well.

 If you don’t know the components well enough to know which ones need monthly checkups and which ones can wait for a seasonal or annual one, then continue reading to learn different components. Otherwise, for a more detailed checklist for HVAC maintenance, check out this article that contains many useful tips and tricks to minimize the maintenance cost as well as different things you should consider for the next maintenance appointment.

Different HVAC system components

So, let’s review some of the major components of these systems.

-          Heat generator

As the name suggests, heat generators produce heat for the air or other fluids directly or indirectly. The most common form of heat generators is furnaces. So consider combustion efficiency for resource control and pollutant emission.

-          Heat exchanger

The heat exchanger is the unit that takes the heat provided by the heat generator and transfers it to the fluid or directly to the cool air.

-          Thermostat

One of the key elements in HVAC systems is the thermostat that includes a temperature sensor to decide when the right time to turn on or off the air conditioner is. Making sure that it works properly is of importance since it can save up money by eliminating the overuse of the system.

-          Air ducts and vents

Ducts enable the transfer of the air throughout different components of the system. Check for leakage in its maintenance to make sure there won’t be any noise when the system’s running and eliminate odors or excess moisture entering into the air.

-          Blower

The blower is the component that blows the air through the heat exchanger into the air ducts. So to make sure the right amount of air is transferred in the system, check out the blower and keep it in good shape.

-          Condenser coil / Compressor

This unit removes the heat from the warm refrigerant gas and takes the heat to the outside environment and turn the gas into its liquid form. Then the evaporator coil will continue the necessary tasks on the liquid refrigerant.

-          Evaporator coil

As I already mentioned, the condensed refrigerant liquid runs into the compressor and is atomized by the nozzles to increase the rate of refrigerant evaporation. The warm air with the help of fans, and goes into the evaporator and its heat will be transferred into the atomized refrigerant. Then the air that’s now cool goes back into the room with the help of ducting.

These were the most important parts, but if you want to read more on the subject, check out this article and learn some great details about them.

Aside from the right maintenance, there’s one more thing that can help increase the efficiency of your system and lower the costs of maintenance: HVAC Economizer!

HVAC Economizer

This economizer can help enhance the economy of your system. This part goes on the exterior parts of the system and evaluates the humidity and the temperature of the air outside to decrease or cut the workload on the air conditioner by using the air outside to cool down the building.

These economizers have different types that are based on the requirements of the system such as dry-bulb.

Economizers have many benefits such as saving you money by reducing the time that the system should work and as a result, you’ll pay a lot less for the electric bill. It can also increase the level of ventilation by monitoring the outside air with the inside and using the outside air whenever possible.

So make sure you check if your HVAC system has an economizer and get one if your system doesn’t have it to reduce costs and increase the efficiency. You can learn more about these economizers here.

Now that you know how to get the most out of your system, you can easily maintain yours and also use the tips and tricks you learned to keep your system in good shape. These systems can be used for industrial, commercial and residential purposes and can keep the air at the desired level to create a comfortable place for you, your family, your employees, etc. Plus, it increases the quality of the air you’re breathing that directly affects your health! So why not using an HVAC system to have a healthier life? If you are interested to receive more information about these systems, click here.

Introduction of electric motors and types

Image
  You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned. An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are  electromagnetic -based. Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused. Types of Electric Motor Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-...
