Awareness of the smart home across various verticals and integration through remote monitoring as well as control via smartphone apps is making residential modular systems more appealing to technology-oriented consumers.

By Type: Water-Cooled Modular Chillers Dominating and Air-Cooled Modular Chillers Fastest Growing

Water cooled modular chillers release heat using the cooling tower or condenser water loop, which is much more energy efficient than air-cooled models. They are ideally suited for large commercial buildings, hospitals, and industrial plants that require maximum efficiency with the capability to handle cooling loads exceeding 500 kW. Water cooled systems have more complicated installation (a cooling tower and condenser water piping), but energy cost savings over the life of the equipment justify this investment with large scale systems.

Air-cooled modular chillers directly reject heat to the atmosphere through air-cooled condensers, eliminating the need for a cooling tower and condensed water system. They are also easier to install, making them the ideal choice for projects where installation simplicity and lower capital cost is a top priority, such as in small to medium commercial facilities (incl. They are useful in applications where water availability is limited and their flexibility makes them a true advantage. Growth within this segment has been driven by the introduction of new air-cooled modular chiller ranges with better efficiency ratings from major manufacturers such as LG, Mitsubishi and Johnson Controls.

By Compressor Technology: Scroll Compressor Dominating Screw Compressor Fastest Growing

Scroll compressors dominate the modular chiller market because of their compact size, quiet operation, reliability, and good energy efficiency at part-load conditions typical of commercial buildings.
