What are chillers and how do they work?
Definition & FunctionA cold water unit, often referred to as a chiller or liquid cooler, is a refrigeration machine used to cool small to large buildings or technical processes.
Unlike a conventional VRF air conditioning system, cold water or a water/glycol mixture circulates as the cooling medium in the building instead of a refrigerant. This is why chillers are also referred to as cold water generators.
Air-cooled chillers dissipate the heat extracted from the cooling medium via the outside air, while water-cooled chillers dissipate the heat via the cooling water. In principle, heat recovery systems (HRS) can also be used for this purpose. Chillers can also be used as heat pumps and can cool or heat with this function.
In addition, there is free cooling technology, in which the cooling medium releases heat directly into the ambient air.
Chillers for a wide range of requirements
chillersAir-cooled chillers
Air-cooled chillers are the most commonly used type of equipment. These chillers are equipped with fans on the condensers and are designed for outdoor installation – however, there are also versions available for indoor installation. The units are compact and quick to install, as they are manufactured ready for operation at the factory. Optional integrated hydraulic modules are often available. Work on components carrying refrigerant is not necessary.
Water-cooled chillers
Water-cooled chillers are designed for indoor installation in buildings. The condenser in the refrigeration circuit is water-cooled. The heat is dissipated via a hydraulic recooling system, which is often equipped with an air heat exchanger (recooler) for outdoor installation, or via geothermal probes or groundwater, for example. Water-cooled systems have a wide range of outputs and are often used in buildings where particular attention must be paid to noise emissions.
Chillers with free cooling
Chillers with free cooling are always a sensible choice when cooling is required even at low outside temperatures.
In this case, the heat energy is not extracted via the mechanical refrigeration cycle in the machine, but rather the cooling medium releases the heat directly into the ambient air. This means that cooling is virtually free of charge. Free cooling is particularly suitable for applications with high media temperatures or for applications where cooling is required throughout the year.

No matter how complex your project is, you can always expect a tailor-made, energy-efficient, powerful, and future-proof solution.
Our products not only comply with current eco-design regulations—we are already developing solutions for future requirements. In addition to specific solution concepts and innovative technology, Mitsubishi Electric also offers you first-class, reliable consulting and services.
Mitsubishi Electric chillers and heat pumps
The latest MECH-iS-G07 and MEHP-iS-G07 series are ideal for a wide range of projects, from IT cooling and process cooling to comfort applications.
They are characterized by first-class energy efficiency and a particularly compact design. In addition, they impress with exceptional efficiency and a wide range of applications. The use of a refrigerant with low global warming potential (R32) further addresses the issue of global warming.
Climaveneta chillers
Climaveneta chillers are available in all sizes and as customized and highly specialized solutions for a wide range of requirements: in addition to various cooling and air conditioning solutions, our brand also offers heating and ventilation concepts. Low investment, operating, and maintenance costs as well as a long overall service life are just as much an advantage as perfect temperature and humidity control, optimized air quality, and low noise levels—for ideal comfort conditions.
RC IT Cooling Chillers
Our RC IT Cooling brand offers a wide range of chillers with magnetic bearing turbo compressors – both air-cooled and water-cooled. The chiller solutions are available with free cooling or with free cooling with an "adiabatic" version for high efficiency in every area of application. In addition to chilled water solutions, RC IT Cooling offers precision air conditioning cabinets, rack coolers, solutions for telecommunications containers, condensers and dry coolers, as well as heat recovery systems.
Large heat pumps as an alternative
large heat pumps
Heat pumps offer convenient solutions for heating, cooling, and hot water production in industrial environments and can also effectively provide process heat. Instead of heating the building conventionally with fossil fuels and cooling it with chillers, a reversible large heat pump can perform both functions.

Requirements for availability in comfort and process applications are met.
Comfort and process cooling, IT cooling
Tailor-made solutionsOur solutions cover both industrial applications, where temperature control for industrial processes or products is achieved using refrigeration systems, and comfort applications, where environmental conditions such as temperature, humidity, and air quality are controlled in areas where many people are present.
Chillers for comfort cooling
for high energy efficiency with low refrigerant consumption. This makes chillers not only particularly safe, but also well equipped for the future in terms of strict refrigerant regulations. In comfort cooling, chillers are therefore often used for cooling and heating as well as for supplying cold and hot water in large building complexes. These can be office buildings, hospitals, government agencies, hotels, or shopping centers.
Chillers for process cooling
High system availability and constant operation with minimal temperature fluctuations: Absolute reliability is required when cooling industrial processes. That is why powerful chillers with precise temperature control and high reliability are used in industrial cooling. They are used in production halls and workshops for machine cooling, process cooling, or even warehouse cooling. Typical industrial applications include the chemical, pharmaceutical, and automotive industries, as well as the plastics, metal, and food industries.
Chillers for IT cooling
The chillers with free cooling function from our RC IT Cooling brand meet the market's requirements for higher water temperatures in data centers and server farms. The system design, equipment, operating data, and control system have been consistently tailored to the specific conditions for IT cooling and perfectly matched to indoor units such as precision air conditioning cabinets. Equipped with mechanical, hybrid, and free cooling options, the chillers operate particularly energy-efficiently all year round. System concepts such as HPC (Hydronic Plant Connect) also offer energy optimization of the entire hydraulic system, from precision air conditioning cabinets and chillers to pump control.
