Geothermal heat pumps are increasingly becoming a common alternative for environmentally responsible HVAC systems these days. The energy savings that geothermal HVAC systems provide cater mostly to the needs of the baby boomer clientele. 

Geothermal energy is most appealing to the millennials, especially after they learn that it is far safer to use than other power options because it won’t put the environment in harm’s way. By the year 2050, scientists are predicting that drill rigs for sale in Australia, together with the rest of the world, will be utilized primarily for the production of geothermal energy.

In line with the statement above, expert minds in the power industry anticipate also an upcoming surge in demand for geothermal power sources. It will supply around 10 to 20% of the world’s energy. Anyone who happens to have a relevant background experience in HVAC should consider learning more about this rapidly expanding sector.  It will be a lucrative career in the coming years.

What Is Geothermal Heating and Cooling (HVAC)? 

The temperature of the earth can be used for heat exchange by virtue of geothermal HVAC and power systems. Even though there are regions on this planet where weather conditions can be very extreme, the temperatures underground are constant. It doesn’t change and will remain as is at any given time. 

High-efficiency heat pumps include geothermal heat pumps. These systems would rely on transfers of heat between the ground and the air to heat up and cool down homes and buildings. There are 2 basic forms for geothermal systems, the enhanced and deep geothermal systems, and the direct-use geothermal systems.

In regions where there is observable tectonic or volcanic activity, you will see that it is not uncommon for people or communities to enjoy access to naturally heated groundwater. This only goes to show that it is normal for them to have direct access to geothermal systems.

As such, hot water is pumped up to the surface so it can be used as-is. Alternatively, they can be utilized in heat exchangers to help in heating up or conditioning that air inside a building or a residential space.  

As for the deep and enhanced geothermal systems, they can be seen used widely powering up large commercial, agricultural, and industrial applications. They rely solely on steam which can be accessed from beneath the surface of the Earth.

The best way to access this steam from underneath the earth, though, is by taking good advantage of drill rigs for sale in Australia.  

What is the Mechanism Behind Geothermal HVAC Systems?

thermodynamicsGeothermal HVAC systems make use of the same refrigeration science as any other equipment HVAC/R. With respect to the Second Law of Thermodynamics, the natural tendency of heat is to spontaneously flow, right from hot or warm areas to colder regions. 

An electrically powered heat pump will cycle fluid, typically a type of refrigerant, or in some cases, water may be used. It is carried out via long loops of the geothermal HVAC system underground pipes. By virtue of this process, heat exchanges from the ambient air in the building to the ground, or vice versa.

During the come winter season, the heat pump will work doubly harder by moving the fluid through the system of tubing. It will be heated up by the soil, colder rock, or water underground. Then the warmed-up liquid will make its way back to the structure.

The heat that comes from the liquid can then be transferred to the building’s heating system to warm the air. To raise the temperature of the water that is intended for domestic use, the use of a desuperheater may be taken into consideration. The cooled liquid will make its way back into the ground so it can be warmed first before being returned to the building.

The same dynamics would happen during the summer. But this time around, the fluid will be made to absorb the heat coming from the air which will be dispersed into the atmosphere. The loop will continue to work.

What Makes Waterjets Cutting Distinct from Laser Cutting Method?

When it comes to their material cutting concerns, companies involved in the manufacturing space favor the use of waterjet cutting and laser cutting techniques. 

With respect to the material in question and the result they desire to have, one of these two methods would be most appropriate for a given application. 

Before making any conclusion that one of which is better than the other, it would help a lot if we will examine first what their fundamental differences are, in terms of processes as well as the materials they are known to work well with. From identifying what their distinct qualities are from each other, we can draw a line on how we can use them for our various material cutting requirements. 

Water Jet Cutting

laser cuttersUnlike laser cutters, a water jet cutting system, denoting its name, makes use of highly pressurized water to cut or slice through a material. Abrasive materials in the form of aluminum oxide and garnets can be used if you want to further intensify their cutting power. 

Besides increasing its cutting ability, the addition of abrasives to the water before getting pressurized will significantly help in reducing cutting time to half. 

The working principle behind the waterjets system of cutting is derived from nature itself, particularly the erosion of soil in mountains. The waterjet technique is, however, an amplified version of erosion. The main difference is that a waterjet is executed at a higher speed and concentration. 

With the help of a high-pressure pump, the water can be driven through rigid hoses. This action will lay the groundwork for a highly powerful/forceful jet of water. 

If laser cutters have their laser source right inside the machine itself, waterjet pumps and work areas are often separate.  

Applications and Materials 

One reason why the waterjet system of cutting quickly elevated itself as the material cutting of choice among many industries is due to its ability to cut virtually any material, even the combination of materials.

If there is one downside to the waterjet cutting system, it may have something to do with the risk of delamination. While it can somehow manage 3D material cutting, it tends to exhibit a limited ability when working on cavities and sandwich structures. 

It is possible to cut materials that pose limited access, however, it may necessitate you to surmount those challenges first. 

Waterjet systems can carry out a variety of tasks such as ablation, structuring, and cutting, particularly on stone, thick metals, and ceramic materials. Materials with a thickness range of anywhere between 0.4 to 2 inches would most benefit from water jet cutting.  

Safety and Precision 

When it comes to precision, laser cutting is a notch higher when compared to the water jet technique. It usually comes with a cut size slit of 0.02 inches. 

Due to the strong amount of force used, thin and small parts will not usually fare well with it. Therefore, extreme care and caution must be observed when handling such materials with waterjet.

Waterjet systems are not known to produce thermal stress on the subject material being cut or sliced through, however, adding some abrasive particles to the pressurized water may run the risk of having a sand-blasted look. 

Additionally, the water jet machine operator will need to wear high-quality goggles to protect both his eyes and face.  

Laser Cutting 

Laser cutting machines depend a lot on a gas laser to work and for its energy requirement. This would include the CO2 laser. Under the guidance of mirrors, pure CO2 will be transmitted through a beam, heading towards the direction of the material. 

The source of the laser in these machines can be located right inside it. As for the laser beam, it can produce an output that is anywhere between 1500 and 2600 Watts. 

handle works

Materials and Applications

Laser cutting systems perform exceptionally well if you are working on materials that are between 0.12 to 0.4-inch thickness. Most of the time, they are taken advantage of in handling and cutting flat sheets of steel with a medium thickness. It is typical for laser cutting systems to handle works involving drilling, welding, cutting, ablation, engraving, structuring.  

Precision and Safety

While safety goggles are not an absolute necessity here, laser cutting systems may generate dust and smoke. If you are working on metals and plastic materials, it may even produce toxic fumes. This goes to show that proper ventilation in your workspace is of paramount importance, and thus can’t be put aside. 

Overall, compared to waterjet cutting methods, there is a minimum amount of risk involved with laser cutting systems. The same is also true when it comes to the subsequent cleanup and the amount of waste produced.

What Are the Things You Probably Didn’t Know Can Be Cut by a Waterjet Cutter?

All it takes is a discerning mind to agree with me in saying that the waterjet cutter is setting a new trend in the space of cutting technology.

So much has been said about how good the system is, how beneficial the method is — but the underlying question that many ordinary people wonder about it is that what can you cut with a water jet machine? 

Beyond plastics and metals, there is more to what waterjet cutters can handle. Some could even surprise us. There is a lot more yet that we can learn about this wonderful material cutting technology.

Without further ado here are some of the important things to know about the waterjet system.  

1.) Food

Yes, absolutely — you are reading it right, food. There is an increasing use or application of water jet systems in the way we handle and process our food today. 

Waterjet cutting is a qualified sterile cutting method, very accurate, and most importantly it does not produce heat. Hence, it is not going to inflict damage to food items that are being cut. 

Water jet systems can be taken advantage of to cut any food item, from chocolate to meat, fruits, vegetables, and pizza. 

2.) Art

When we speak of the waterjet’s involvement in art, we are not referring to the paint on the canvas art style. What we are pertaining to is art installations, beautiful floors, and sculptures. 

Waterjet systems make it possible for artists to make their vision and art become a reality. It allows people with the most creative minds to focus and center their energies on being creative. 

artwork

The role of the water jet cutting system here is to make the actual piece as opposed to sculpting the concept manually. 

3) Steel bars

This also applies to any other type of thick bars.  It is easy to think that water jet systems aren’t that strong or powerful enough. Even more so when you put it side by side in comparison with many other fancy techniques in cutting such as laster. However, the opposite would be true here. 

While laser cutters can make a marvelous job of cutting through an impressive 2.5 centimeters of plastics and metals, the water jet method can outmatch that feat at least 10 times more of that depth.   

4.) Bulletproof glass

A waterjet cutter can cut through bulletproof glass. As we know this type of glass is capable of withstanding hundreds of rounds of bullets being fired at it, right? 

If this material is as tough as that, can deflect bullets being fired at it, and yet a waterjet cutting can slice through it in a seamless fashion then it only goes to show that this material cutting technology has more to offer.  

5) Complex three-dimensional parts

When it comes to material cutting technologies, our natural tendency is to see them in a boxed-type of mentality. We always imagine that they cut out a flat shape material, that if you require a more intricate part then it will involve additional cuts. 

It is essentially a cutting job done in stages, that is you cut first in one axis and then you will move it and then proceed to cut another axis. Repeat as necessary.  

Needless to say, such a cutting approach is time-consuming and is prone to committing errors, too.  

Waterjet systems finally addressed this issue because it comes with a cutting head that is capable of moving in multiple axes.

This only goes to show that even when you are working on an intricate 3D part, you will have no trouble with the execution of the cutting work since you can slice through in one fluid motion.
