Copeland Scroll Compressor


A scroll compressor is also referred to as a spiral compressor, a scroll vacuum pump or a scroll pump. All these terms point to a device manufactured specifically to do the job of compressing air or refrigerant. The primary use of this device is in air conditioning systems. A typical scroll compressor uses two interleaving scrolls to compress, pump or pressurize gas and liquids. Today Copeland Scroll compressor technology is one of the leaders in this field. Their products are known far and wide for its superior efficiency, proven reliability and ease of installation. The company also has one of the broadest product line in the industry that can be used in singular or tandem configurations and be modulated to increase efficiency and comfort for the consumer.

The design benefits of the Copeland scroll compressor are many. It provides better liquid handling meaning protection against liquid damage. This can be managed because the axial and radial compliance separate in the presence of liquid refrigerant. The device provides greater efficiency in comparison to other competitor operating range products in the market. It also produces less sound and very low vibration levels in comparison to other traditional compressors available these days. Other aspects that put this company at the highest level of achievement over others is that the products have unmatched reliability. With 70% fewer moving parts within the unit, ability to start under any adverse conditions including system load, compact in size and lightweight makes it easy to service and maintain, simple in design, engineered for optimum performance with today’s chlorine-free refrigerants, and having no complex internal suction and discharge valves for quieter operation and higher reliability, the company is a undisputed leader in residential as well as commercial units.

The journey for this brand does not end here. The company has its eyes set on making the products more environmentally friendly, provide indoor comfort and better efficiency, even though at the present time itself this innovative technology is enabling air conditioning systems to operate at an energy saving two-thirds capacity approximately 80 percent of the time.

In view of the fact that a Copeland Scroll compressor can help reduce energy use by 20 to 60 percent in a home unit, there are a large number of companies from around the world that are switching to such innovative technologies for their air conditioning products to tap into perks like having a product range that gives high energy savings, uninterrupted cooling performance, lowest environmental impact, lowest life cycle cost by design, and longer tube length. With so many advantages on your side, it is no wonder more and more air conditioner manufacturers from around the world are now looking at Copeland Scroll for further enhancements in the systems and developments to take the industry a notch or two further.

Facts about AC Drive


There was a time in manufacturing history of air conditioners when speed control from a singular motor was achieved through a series of large pulleys that would power the large flat belts. The various sizes and combinations of these sized pulleys and belts together decided the speeds. Being extremely inefficient and hazardous as the pulleys were open faced and exposed. Eventually smaller belt and pulley systems were invented and electric motors became compact and although the efficiency was still lagging behind. The problem was effectively solved with the invention of modern AC drives. These drives operate on the principle of controlling the frequency of the AC, which is sent to the motor. The adjustments on frequency also affect the voltage, while the amount of power delivered to the moving motor remains constant.

There are many ways of referring to AC drives in the industry. They may be called Inverters, Variable Speed Drives (VSD), Variable Frequency Drives (VFD) or Frequency Converters, as their primary function is to control the AC induction motor. A distinctive feature of AC drives is that by controlling the frequency delivered to the motor, they can monitor any adverse or overload conditions experienced by the unit due to things like equipment failure, electrical flouting and the like. In view of this fact, plenty of manufacturers these days are setting the AC drives to cease operation at any minor infraction that may cause harm to the motor. This saves manufacturers huge amounts in motor replacements. Some leading manufacturers even have intelligent drives that have programmable automation or motion controllers within the product to eliminate communication delays, improve performance, efficiency in motion application, save panel space by removing the need for external controls.

The chief reason for the demand of such drives is the energy consumption factor. It is estimated that such drives end up saving up to 20% more energy if installed and operated in an efficient way. These AC drives also play a key role to reduce carbon emissions into the environment, taking into consideration that the motors consume almost two thirds of electrical energy. Since energy efficiency, money saving and environmental conservation are three important aspects in buying electronic products, the significance of AC drives can be realized.

The need for buying a product with a high quality AC drive is very high nowadays, when the value of money is so high, thanks to the extreme inflation. In fact, a majority of smart buyers in the market ask for details and specifications of the product. Some of the frequently asked questions include inquiries about the AC drive and in turn the energy star ratings, efficiency of cooling, tonnage and size, product reputation, installation charges, product life cycle, etc.
