It is the strong affinity that these two substances have for one another that makes the cycle work. Chiller costs consume a substantial part of your building’s utility bills. What measures should one take to obtain energy savings through maximal efficiency of the chiller system? Commercial buildings use Heating, Ventilation and Air Conditioning systems to dehumidify and to cool the building. Modern commercial buildings seek efficient HVAC systems and components as part of broader initiatives centered on building performance and sustainability.
Since 1969, Thermal Care has been a leading manufacturer of portable and central chillers in air cooled, water cooled, and remote condenser models. Remote condenser systems allow you to place the condenser and compressor in separate areas.
Centrifugal compressors have very few moving parts which makes them a favorite in the industry. They are more energy efficient than their reciprocating counterparts, and provide a greater flow of refrigerant than a similarly sized centrifugal compressor. They also require less maintenance, although regular inspections should still be scheduled. Reciprocating compressors use pistons driven by a crankshaft and deliver a small amount of refrigerant at very high pressure. Because of their relatively low price point they were popular in the past, but issues with noise and reliability have made reciprocating chillers less popular. Regular maintenance and upkeep are very important with reciprocating chillers.
For larger industrial cooling and refrigeration applications, these air- or water-cooled industrial chillers can handle the job. Available in HP compressor power, our semi-hermetic chillers come with many customization options to meet your project needs. Available as an air- or water-cooled chiller, our scroll chillers come with compressors ranging from 2-34 HP. They use a set of interlocking scrolls to pressurize the refrigerant inside the compressor. Scroll chillers work well for small or single equipment cooling needs and are excellent for sporadic process applications that run less than 24 hours per day. Industrial lasers are used for a wide range of applications including cutting, welding, micro-machining, additive manufacturing and drilling.
This integrated package keeps installation costs down, provides a single source of system responsibility and minimizes the foot print required. Also available is Aggreko’s line of low temperature process chiller rentals. These have a modular design, can fit infinite size requirements, and can be engineered to specific process applications.
Pulsating pumps still offer the required system cooling, but create vibration within the cooling system. In laser systems, this has similar effects to thermal instability and results in a less focused laser beam and lower quality performance, which is critical in cutting and engraving applications. Industrial lasers are commonly used for cutting hard materials like steel. Basically, the laser beam melts through whatever material it is focused on. When cooled efficiently, the laser beam creates a finer, more precise cut or engraving. If the laser beam operates outside the optimum temperature range, it is not as focused and creates a rougher, less precise cut or engraving.
The refrigeration cycle begins with a low-pressure liquid/gas mix entering the evaporator. Inside, heat from the process water or water/glycol solution boils the refrigerant, which alters it from a low-pressure liquid to a low-pressure gas. The low-pressure gas enters the compressor where it is compacted to high-pressure gas. The high-pressure gas enters the condenser where ambient air or condenser water subtracts heat to cool it to a high-pressure liquid. The high-pressure liquid then goes to the expansion valve, which controls how much liquid refrigerant enters the evaporator, ultimately beginning the refrigeration cycle all over again.
Common refrigeration compressors include reciprocating, scroll, screw, or centrifugal. These can be powered by electric motors, steam turbines, or gas turbines. Compressors can have an integrated motor from a specific manufacturer, or be open drive–allowing the connection to another type of mechanical connection.
Chilled water systems are closed-loop systems, meaning that the system water is continually recirculated and not exposed to atmospheric pressure, similar to domestic water systems. While selecting the type of chiller to use is generally dictated by capacity, there are still many philosophies on the best way to control, operate, and calculate system operational costs. Ingersoll-Rand Company manufactures tools and equipment such as chillers, air and electric power tools, material handling equipment, fluid handling products, vehicle service tools, and dispensing systems. Their services include ergonomics consulting, installation, preventive maintenance, system monitoring, repair service, assembly solutions, aftermarket parts/service, and industrial productivity. Chillersare machines that remove heat and generate cold or chilled liquid by removing heat via compression or an absorption refrigeration cycle.
As a long-time chiller supplier for many medical facilities, our industrial chillers can provide exact performance as medical standards request. Without proper cooling time, there will be likely a large number of defects. And as the cooling time is about 90% of the total cycle time, effective industrial chillers can reduce production time and increase efficiency. However, the types of industrial chillers are different, and the control panels used are different, so the industrial chiller temperature settings are not necessarily the same. It can provide low-temperature industrial chillers below -15 °C ~ -35 °C, usually used in chemical and pharmaceutical industries, for reactor cooling or material condensation recovery. Inside the compressor, the refrigerant is compressed and its temperature and pressure are increased.
We specialize in packaged industrial chillers ranging in size from 1/2-ton to over 200 tons. These units are designed for indoor or outdoor installation, and operate efficiently in ambient conditions of -20º F. This Powerchill Package takes the guesswork out of sizing a cooling water supply.
Zero Zone Industrial Chiller Systems are engineered to provide superior flexibility and reliable performance. Features include rugged mechanical components and microprocessor controls, and systems are pre-piped and pre-wired on a structural steel base. Our Chiller Systems utilize a standard design platform with components custom-selected for the specific project needs. In most situations, a chiller on the fritz will mean hours of downtime and productivity loss.
When a chiller is substituted for city water being wasted, the payback can be as short as a year. Fortunately, manufacturers have been successful with finding a solution to insulate the pipes. These pipes have two insulating features—a built-in insulative coating and an external thermal insulation blanket. With these two features working together, they help contain the cool air inside the pipes and prevent contact with the air surrounding them. These systems are designed to accommodate for any network of chiller pipes, regardless of how complicated the layout may be.
Chilled water system is a machine that cools normal water through the chiller’s compressor to a certain temperature to strengthen the cooling process and generate a lot of heat. “Process coolers for industry provide a high and constant degree of precision of the output water temperature and keep the fluid clean to prevent damage to the end user. The industrial manufacturing sector may have a greater need for compression water cooling units that can be sub-divided, depending on the fluid used for the cooling of the condenser, into air-cooled and water-cooled.
