How HVAC Temperature Controllers Work

Most of the HVAC systems that people have nowadays always had thermostat and temperature controllers. Heaters and air conditioners do not just simply turn up and turn down the temperature in a room or in a building. You can adjust it to the temperature that you want to have inside your room.

Temperature controllers are devices attached in the HVAC system which receives input from the sensors. The sensors give a signal to the controller that tells it what the current temperature in the room is. It then puts an output to the system which will either drop or increase the temperature. This of course depends on how you have set the temperature in the room or how you have scheduled it. The temperature controllers help check one thing you need to worry about.

Controlling the Temperature

Unlike in nature where you do not have the control whether how hot or cold is it going to be on certain days, you can always control the temperature inside your own homes or offices or any establishments. With the HVAC systems, even if it is hot outside, you can still feel cool and comfortable inside. You do not need to worry, as well, if it gets too cold because, through its temperature controllers, you can set it according to the temperature which you can tolerate and will make you feel comfortable.

 The temperature we are in greatly affects the activities we can do. Our bodies depend on the temperature around us. So, if it is too cold and you cannot tolerate it, or you cannot adapt to it, you cannot work properly. You cannot even relax. If it is too cold outside and you want to feel warm inside the room, you will still feel uncomfortable if it gets too hot. You may end up getting sick because of the sudden changes of temperature in the body.

HVAC Temperature controllers are designed to help control the temperature as well as keep the HVAC system in good condition. Even machines and equipment cannot last long. The estimated life of HVAC units lasts for 15 to 20 years. Some do not even last this long. In order that it lives longer, it has to be maintained regularly.

Here are some steps that you can check regularly so your HVAC system lasts longer:

•             Clearing of clogs

•             Checking of electrical wirings

•             Regular cleaning of the unit

•             Check for leakages

The Important Function Of HVAC Control Valves

A control valve is used to control the flow of fluid depending on how fast or slow the flow of passage is as signaled by the controller. Aside from the control of the flow rate, it also controls the pressure, temperature and liquid level. Without it, it would be impossible to control the flow of the components of the HVAC system as it plays a vital role in controlling the system’s temperature.

Types of control valves

  • Globe Valves
  • Solenoid Valves 
  • Butterfly Valves 
  • Ball
  • Zone Valves 
  • Non-Electric
  • Industrial Valves 

In HVAC systems, control valves serve a huge role. It can be controlled in many ways and comes in a wide variety of shapes and sizes. To know which valve is the right one, you need to consider these:

  • Size of Valve Pipe and the flow capacity – Not every valve that you replace is specified correctly, a lot of them don’t control correctly and could be oversized.
  • Connection of Valve body & pattern – 2 way valves, 3 way valves, straight valves, mixing valves, diverting valves, screwed connection, sweat connections, union connection, angle valves, flanged valves, half union valves, flared valves, -, normally open valves and normally closed valves.
  • Actuation- electric, pneumatic, electronic, 2 position, pressure, floating, modulating, self-contained (thermal).

HVAC control valves is important in the systems and it needs to be the right type valve for your equipment. Aside from that, it should be set in a setting that is perfect for your building, location and the weather in your area. Otherwise the flow of control will not work as how it’s supposed to be and can cause damage in the system. And a damage in the system can pose a threat not only to the units and the building but also to the well-being of the people within the establishment. It is recommended that your system should be maintained by a certified HVAC technician as they are the ones that are experts in the field.

It may seem like a small part of the system but it does play a big role with regards to the controls of many components of the system. How you make your settings, how you control it, and maintain it matters and every small decisions in the system could create a huge impact in the function of the HVAC system as a whole. SO it is always good to take special considerations and planning and know the importance of everything in the system.
