Scroll Technology

Today Scroll technology has replaced conventional piston compressor technology as the industry standard. The compressor is much quieter, reliable and energy efficient as compared to others. For the longest time people from countries with developing economies such as India were apprehensive about buying air conditioning systems for their homes and offices because of the running costs of AC units. The electricity bills would be quite a bit higher than before the system was installed. Being the heart of the AC unit, the traditional compressors were responsible for high electricity consumption. Because of the introduction of scroll technology in air conditioning systems, now manufacturers have an opportunity to continue and use such advance air conditioning technology for better energy efficiency and responsible use of refrigerants.  

Leon Creux was the person who first patented the scroll compressor in the United States of America and France in the year 1905. Since at that time, high tolerances required in sealing the compression chambers were unavailable, these compressors were not used. The concept was only revisited in the 1970s, after which new modification were made to the technology and used in HVAC products. Today however, the scroll technology is considered the most modern and apt for cooling products. There are quite a few advantages of using such innovative technology in HVAC instead of the traditional compressors. Some of the benefits are in aspects like reliability, efficiency, vulnerability and size.

Compared to other compressors the compressors made using scroll technology have fewer moving parts. This translates into more reliability, less maintenance and lesser noise. There is less chance of a breakdown in the system since this compressor has no valves. The design of a scroll compressor allows it an ability to produce higher cooling in comparison to the older models. This means energy efficiency and less electricity bills for the consumer. Not only is this aspect profitable for the individual or business using such cooling solutions, but also for the environment as it generates lesser carbon footprint. The new scroll technology compressors are compact and well-balanced. While this does not make a big difference when it comes to small air conditioning units for homes and offices, it does make a huge difference for commercial units. In the olden days large commercial complexes or supermarkets would need a separate room to keep them. The new technology saves consumers space as well as money spent in accommodation of the compressors.

Most wise consumers these days, not only look at brand name, reputation of the company, design of the model, and star rating, but also pay attention to the mechanism used to make the product. As a consumer the best way to save on energy and electricity usage, is to buy an air conditioning unit that uses scroll technology in their compressors. In India, most reputable brands known for their air conditioning units use this technology in their products.

Things to Know About Scroll Technology

Even though once you see how the scroll technology works, you are bound to think it is very simple, the fact remains that it is a fairly new technology that has revolutionized the refrigeration industry. According to the Ashrae’s HVAC Systems and Equipment Handbook the scroll compressors are defined as orbital motion, positive displacement machines that compress with two intermitting spiral shaped scroll members. It is believed that the first scroll compressor patent was out in the market as early as 1905, developed by a French engineer named Leon Creux. Quite ahead of its time, this compressor was not used much until the 1970s when the machining technologies were advanced enough to tap into its potential. Development continued and today scroll technology is used in a number of commercial and residential applications.

These days scroll compressors are manufactured by a large number of companies from around the world. While there may be slight differences in the shell design, scroll geometry, oil selection and so on, the basic mechanism and the fundamental features remain the same. In the last few decades the scroll compressor has proved that it is reliable and in many ways better than other technologies available today. Manufactured in a host of size up to 25 tons for large industrial use, scroll compressors are widely seen used for grocery display cases at supermarkets, bulk milk cooling units, air conditioners, refrigerators, marine containers, water chillers, large split condensing units, automotive air conditioning, etc.

Here are some of the advantages of the scroll technology compressor. It has excellent efficiency for full-load as well as part load. The unit has very few moving parts (three), which translates into less noise while running and also low vibration as compared to other technologies and Copeland compressors. This contributes to having less maintenance in the long run. The precise machining permits sealing vane flanks with a thin film of oil. Designs where there is no contact between the two scrolls are proven to be more efficient due to very less friction.

There are two sides to every coin, and since we have taken a look at the many advantages, it is only fair to know the disadvantages as well. There are two main drawbacks to the scroll technology compressors, and they are: the compressor cannot be disassembled for maintenance at the place of installation. Also, in places where multiple compressors are in use there is an incremental capacity on systems.

One of the most important reasons for the growing popularity of scroll technology compressors is that it saves energy. These compressors can produce powerful cooling without using a lot of power. This means lower electricity bills for the consumer, and better conservation of the environment. It is truly a win-win!

AC Drive

The AC drive market is growing at almost 10% per year, and a major credit for this change is due to the development of AC drive technology. It is important to know that the technology used in AC drives is completely different from other simpler control methods. Use of these drives has many cost benefits as well and this fact makes them a sure shot winner in industries as well as home owned products. Let us take a quick look at the main benefits an adjustable speed AC drive can provide industrial users.

Normal motors take on too much current to start the motor, which damages the device over the long run. This also places a tremendous drain on the power distribution system connected to the motor. These sags in voltage can harm other sensitive equipment connected to the distribution system. On the other hand an adjustable speed AC drive starts a motor at zero frequency and voltage. This translates into better longevity of the motor and therefore the machine. Also, these drives curb voltage sags to avoid damage of any other equipment or machines connected to the same distribution system. The controlled starting current also makes a difference in the electricity bill you incur each month.

AC drives have controlled acceleration as well. They start at zero speed and slowly and steadily accelerate on the ramp. This is not the case in other AC motors that start abruptly creating a kind of shock to both, the machine as well as the load and motor. Such rapidity creates more wear and tear on the connected load and motor. Also, many older motors have only a few operating speeds, whereas an adjustable speed AC drive enables adjustable operating speeds by programmable controller or process controller. They also have an adjustable torque limit, which allows the motor to not ever exceed the designated limit. Controlled stopping is also as important as controlled acceleration to ensure minimal mechanical wear and tear. This too is ensured in AC drives.

Centrifugal fan and pump loads operated with an Adjustable Speed AC Drive reduces energy consumption, and this is a crucial aspect since energy savings has become a motto for more and more industries to curb the global warming problems. Plus, in view of the fact that AC drives save energy to a large extent, they pay back the capitalized cost in a matter of just a few years, depending on the size of the motor you have bought.

You can also eliminate the purchase of expensive mechanical drive components such as gearboxes, etc, by using an adjustable speed AC drive, given that the AC drive operates at variable speeds and can deliver low as well as high speeds required by the load.

Copeland Compressors and the Advantages of Using Them

Having a decent cooling system can be the difference that either sets the ambiance for efficient work and comfort or causes a state of total discomfort and annoyance, leading to a growing sense of agitation in a work place. Copeland compressors, on the other hand, go beyond just setting a comfortable ambiance for efficient work, they raise the standards to better cooling, energy saving and compact systems that not only work on creating a general mood of satisfaction but also work on saving the environment.

With climate change being an extremely relevant issue in our daily lives, the use of cooling systems such as air conditioners and refrigerators has increased at an alarmingly high rate. This leads to the overusing of appliances, causing them to break down much faster than what their warranties promise, as well as an added burden on one's electricity bills and more harm to the environment. Copeland compressors prevent all of these from taking place through the sheer ingenuity of their advanced mechanism.

The air conditioners function of cooling is undertaken by its compressor, which converts low pressure cold air to high pressure warm air to maintain the atmospheric temperature around it. Copeland compressors are made of spiral compressors or what is also called a scroll compressor that consists of two spirals. The outer spiral remains stationary while the inner one rotates in order to create air pressure. The body of the compressor is known to have 70% parts lesser than most standard compressor models, which attributes to the overall compact body of the cooling system, taking up far less space and being much easier to transport. Other than this, Copeland compressors are known to reduce the energy usage in a home by around 20-60%, saving not only the energy itself but also on the electricity bills at the end of the day. When compared to other cooling models, the compressor is also cheaper and more reliable as fewer parts mean fewer breakdowns and repairs. Marinating a Copeland compressor is also much easier due to this reason. The compressors are also built to withstand liquid and, thus, the mechanism is not harmed in the event of a leakage of fluid. Additionally, due to its structure, the compressor is not as affected by voltage fluctuations as its counterparts, essentially because it is so compact.

So, when you're in the market for a new cooling system for your home  or a commercial area, be sure to conduct enough research on the compressor to make an informed decision as the efficiency of an air conditioner cannot be judged simply by design, size or only its brand. Make sure that your cooling system caters to your needs and to the needs of the environment. 

Scroll Technology – The Future of ACs

One of the most vital components of an air conditioner is its compressor. The compressor works on turning cool air with low pressure into hot air with high pressure in order to maintain the cooling of the area it's installed in. As a consumer, if you're interested in using a compressor that saves energy, has fewer parts, is easy to install and also saves your money, you should consider using scroll technology in your air conditioner or refrigerator.

In a world that's growing hotter by the minute, the importance of a good air conditioning system is undisputed. Choosing an air conditioning system that fits your needs, however, is a harder task than it looks as most consumers are easily swayed by catchy advertisements shown on the television. Apart from looking at features such as design, size, shape and brand, one must conduct some research on the mechanism of the air conditioner or refrigerator in order to make an informed decision. Most of the functioning in an air conditioner is taken care of by the compressor, which not only makes sure that the hot and cool air are well circulated and pressurized, but also that the machine itself suffers no harm.

A compressor that uses scroll technology provides one with various advantages, such as lesser disturbances in terms of noise due to fewer vibrations and the ability to place it almost anywhere due to its compact size. Having lesser parts than any other compressor ensures that there are fewer breakdowns and that there is higher efficiency. While these compressors produce the same amount of cooling as the other standard compressors, they manage to do so while using a lesser amount of energy, thus saving not only on your electrical bills but also contributing to the idea of sustainable development and using resources in a manner that helps preserve the environment. Studies have shown that these compressors reduce the energy usage by 20-60% in a home.

Compressors using scroll technology also have better protection against liquids so in the event of a fluid leak in your air conditioning system or your refrigerator; the mechanism itself will not be harmed.

Scroll technology owes its reliability to the fact that its prototype was invented in the early 1900s, giving the technology ample time to develop and re-develop in order to suit the changing needs of its growing consumer base. The compressor itself is made up essentially of two scrolls, that is, spirals. While one remains stationary, the other rotates inwards in order to create a higher air pressure. As this form of compressors have up to 70% fewer parts than most models of compressors, it gets the job done much faster and better than heavier, bulky models.

Thus, one must make an informed decision when considering buying a new cooling system. When you're going in for an air conditioner or refrigerator and are concerned about factors such as size, efficiency, energy saving and lower price, scroll technology is easily the best option for you.
