The substitute for freon, "HFC (hydrofluorocarbons)," is widely used as a refrigerant in many devices and equipment. However, although HFCs are not ozone-depleting substances, they have a significant greenhouse effect, being 100 to over 10,000 times more potent than carbon dioxide, and measures for reduction have been considered necessary. Due to the impact of HFCs, the average temperature increase by the end of this century is estimated to be about 0.5 degrees Celsius. In this context, from October 10 to 14, 2016, the 28th Meeting of the Parties to the Montreal Protocol was held in Kigali, Rwanda, where an amendment to the protocol (the Kigali Amendment) was made to establish obligations for the phased reduction of HFC production and consumption.

How to control energy consumption in stores, offices, and factories is an important issue for any company. In particular, energy management systems (EMS) that centralize and optimize energy use are gaining attention, and there are increasing examples of their implementation. EMS is a system that integratively manages the equipment introduced by each company for the purpose of energy conservation. It combines energy-saving functions from individual equipment and systems to make adjustments that maximize effectiveness. To achieve this, a support role that can provide services from a comprehensive perspective is necessary. Energy management service providers take on this support role. *For more detailed information, please refer to the related links. *For more details, please check the PDF materials or feel free to contact us.

Which cooling system is more suitable for data centers, air-cooled chillers or water-cooled chillers? There is not just one answer. Designers of air conditioning systems need to ask many questions before proposing the appropriate type of chiller. Factors specific to the project, such as available space, backup power, regional regulations limiting power and water usage, and the owner's sustainability priorities, can overturn what was almost considered a definitive choice of equipment. It is ideal for data centers to consult with air conditioning companies in the preliminary design phase to identify solutions that meet both short-term and long-term goals. If you are making decisions for a data center, it is helpful to understand the specific advantages and disadvantages of each type of chiller.
