A Frigel chiller, which is now also referred to as a cold generator, is available in various types characterized by the technology used to cool an area, substance, or environment. The commonly used types of frigel or industrial chillers are as follows:
Air-Cooled Chillers:
An air-cooled chiller uses air at ambient temperature as the cooling medium. The condenser in the air-cooled chiller is designed to reject heat to the surrounding air. It performs the cooling processes with the aid of fans and convection. An air-cooled chiller functions similarly to an air conditioning system, which absorbs heat from indoor spaces and releases it to the outside air. The absence of water requirements for functioning allows an air-cooled chiller to be installed in multiple areas.
Water-Cooled Chillers:
Water-cooled chillers use water for rejecting heat in the cooling process. The heat is removed with the help of water that circulates through the condenser. This allows for efficient heat transfer. Water-cooled chillers often function better than air-cooled chillers in terms of efficiency. Yet, they require consistent water flow in their cooling systems to function properly. A water-cooled chiller can be incorporated more easily into a centralized cooling system.
Liquid-Cooled Chillers:
The liquid cooling chiller circulates a refrigerant liquid to absorb and transfer heat from a specific area or process. Generally speaking, the refrigerant goes through a cooling cycle in which it absorbs heat, which is then released during the condenser phase. For industrial applications, especially when large quantities of heat must be extracted, a liquid cooling chiller is effective and appropriate.
Absorption Chillers:
Absorption chillers differ fundamentally from vapor compression chillers in that they do not depend on mechanical work to cool. Instead, they rely on heat to drive cooling cycles. Absorption chillers typically use lithium bromide or water as the absorbent and refrigerant, respectively. Frigel absorption chillers are widely used in large-scale industrial facilities and commercial buildings.
Modular Chillers:
A modular chiller is a unit that can be easily scaled up or down to satisfy changing cooling demands by adding or removing modules. Modular frigel chillers provide flexibility and save energy by only using the modules needed to deliver the necessary cooling power for specific applications. Modular chillers are easy to install, function, and maintain. They can also be used in a variety of settings, including industrial production lines and commercial refrigeration systems.
Frigel has several types of industrial chillers, each with various models. Here are some detailed specifications of them.
Frigel bears:
This type of chiller has many configurations. Its cooling capacity ranges from 3 to 40 HP, and it works with different refrigerant gases, with an energy efficiency ratio of more than 7.5.
Modular Frigel chillers:
MI-ILM modular chillers have a considerable power range that can be expanded, and the cooling power can be increased up to 600 HP. The machines are combined with different groups, each with a different power to meet customers' demands.
Frigel Laser chillers:
This kind of Laser Chillers has a series of Laser chillers for cooling systems. At the same time, it has powerful refrigeration units and can provide a stable temperature. This ensures that the customers' equipment can work optimally and maintain its high quality.
Frigel Laser chillers include the standard models CGLST-050, CGLST-090, CGLST-120, and CGLST-150. The cooling capacity is available in different units such as kW and ton. For example, the CGLST-150 model has a cooling capacity of 53.6 kW/15.5 ton. In terms of temperature control, the chillers can regulate the working temperature within the range of -5 to 25 degrees Celsius, with a temperature control accuracy of ±0.5 degrees Celsius. The refrigerant used by chillers is R-407C, and the energy efficiency ratio(EER) is greater than 7.5. Operating voltage is typically 380-415V, and power is typically 25 HP.
Climate change has raised awareness of industrial refrigidation chiller systems in reducing overall energy and carbon emissions. Maintaining Frigel chillers is vital. An effective maintenance schedule helps businesses decrease downtime by sustaining the units' operating capability and prolonging their lives. More essential, routine inspection and repair can avert unforeseen malfunctions that could pose safety threats to employees or customers.
Chiller maintenance basically includes preventive care, predictive analysis, and quick repair of minor problems before they worsen. It begins with regular inspections for leaks, unusual noises, vibrations, or functional anomalies. Components such as filters, coils, fans, condensers, evaporators, pumps, and controls need frequent checks and cleaning to eliminate clogs or contaminants. Refilling refrigerant R-407C is necessary if any has been lost due to slow leaks. Every component must function well, so electrical connections, insulation, and instrument calibrations also require monitoring.
Frigel has excellent services for customers. Refrigerators are crucial to industries. Regular maintenance helps them work well.
The applications for frigel chillers depend on their specific features and characteristics. Generally, they are commonly used in the following industries:
Choosing the right frigel chiller requires careful consideration of various factors to ensure optimal performance, efficiency, and suitability for specific needs.
Q1: How does a refrigerant chiller work?
A1: Frigel chillers work by evaporating water. An evaporator cools water, which a pump circulates. Cooled water absorbs heat from the air in the evaporator. Refrigerant vapors released in the condensers are back to the cycle after the heat removal process.
Q2: What is the lifespan of a chiller?
A2: A well-maintained industrial chiller can last up to 20 years or more.
Q3: How often should a chiller be serviced?
A3: Generally, a chiller should be serviced at least once a year. Some critical cooling applications might require more frequent servicing.
Q4: What are some signs that a chiller is failing?
A4: Some signs of chiller malfunctioning include fluctuations in the temperature of the chilled water, strange noises from the chiller, and constant breakdown and need of repair.
