There is a very fine range of temperatures in which humans will feel comfortable. Even a slight variation can result in health issues which are impossible to overcome, with both heat and cold putting your body under a lot of stress. As time has gone by, people have slowly mastered this, with shade and fires being used in the past, and HVAC systems being popular in the modern world. Of course, though, temperature control has gone far further than simply keeping humans comfortable. To give you an idea of where technology like this is used, this post will be exploring some of the key uses for temperature control in the modern world.
First, though, it’s a good idea to have an understanding of how these systems work, as they aren’t too complicated. There are a few main components which can be used to create a basic temperature control system, and most people would be able to piece something like this together for their own home with just a small amount of research. You can find some examples of the pieces you’d need below.
Thermostat: Most homes use a thermostat to keep themselves at the right temperature. These small devices act like automatic switches, turning on and off when specific conditions are met. This will usually be a minimum or maximum temperature. These enables people to control the temperature of their home, while also saving the effort of turning heating on and off whenever they want to make the place more comfortable.
A Heater: Modern heaters have been around for a long time, though there are several methods which are used to achieve higher temperatures. The most common of these will involve some sort of heating element. This will be a piece of metal with very low resistance which electricity is passed through to create heat, and they are very easy to control. Along with this, though, gas burners are also very common, though these are less accurate.
A Cooler: Cooling something down is a lot more complicated than heating it up, as you have to take the heat and put it somewhere else. Liquid-filled radiators are often used for this, with air being pushed through a grid with a very high surface area to lower the temperature of the water inside. Of course, there are other ways to cool things down, with a liquid spray also having a big impact, though this is most commonly found in server applications.
An Insulated Chamber: There isn’t much point in trying to control the temperature in an outdoor space. Instead, when approaching something like this, engineers will often start with an insulated chamber, whether this is a room, the inside of a fridge, or even a computer. This makes the process of changing the temperature far more effective, while also ensuring that proper measurements can be taken.
Where Is It Used?
Temperature control has many uses, though most people will only be able to think of one or two of them. As time has gone on, the need for this sort of technology has only been increasing, with people across the world looking for ways to take control of their environment. There are some examples of where this tech is used below, giving you the chance to develop an insight into this complex market.
In Homes: Controlling the temperature in your home is crucial if you want to stay healthy. People can’t live in places which are too hot or cold, and this is especially so for the young and old. In some places, heating is used the most, as the weather outside will be very cold. In others, though, people will use air conditioning to cool the air around them, but this is mostly in hotter places.
Fridges & Freezers: People have been using ice to keep food from going off for a very long time. In fact, long before the use of electricity for this task, people would work extremely hard to create spaces which could be kept cool, usually relying on spaces beneath the ground for this. A modern pharmacy fridge is far more complicated than this, giving medical professionals the chance to control temperatures to an incredibly fine degree. This isn’t used for food, though, instead holding samples and treatments.
Servers & Computers: Computer processors produce a lot of heat and can easily destroy themselves if they are left to their own devices. This makes it crucial that they are kept cool, and air is often used for this job. In more complex or powerful systems, though, this can get a lot more complicated. Liquids are often used, flowing in a system similar to what you’d find inside your car. Unlike a car, though, these loops have to be carefully designed, as the machines ability to work will be largely based on their temperature.
Transport: Finally, as the last use of temperature control, it’s time to think about transport. There are a lot of goods which have to be kept hot or cold during transit, and this makes moving them very difficult. To overcome this, some trucks are built like freezers, with think insulating walls, and a compressor which can be used to lower the temperature. Control is crucial for this, as it enables the companies which rely on these machines to keep their products from being wasted.
Temperature control is a lot more important than a lot of people realise. While this field isn’t anything new, there are advancements being made all the time, and this is something which most people know little about. This technology keeps your food in the right conditions, can provide you with great comfort, and, most importantly, could even save your life, making it far more crucial than you might think. Of course, though, the best tools aren’t used in homes, and you have to look further if you want to learn more about this field. Hospitals and food places are a great place to start, though you could also think about the devices you use each day.
