Comfortkoeling

Comfortkoeling is a term used in Dutch building and HVAC literature to describe methods and systems intended to maintain indoor thermal comfort during warm periods. It focuses on occupants’ comfort rather than industrial process cooling, addressing temperature, humidity, air movement and indoor air quality.

Technologies range from active systems such as split and centralized air conditioning units, heat pumps, chilled beams and ceiling panels, to cooling through ventilation and dehumidification. Radiant cooling, radiant floors or ceilings, and chilled water systems can provide cooling with lower air movement. Passive measures such as shading, high-performance insulation, airtight building envelopes, cool roofs, thermal mass, and night-time cooling through natural ventilation complement mechanical solutions. The choice of technology depends on climate, building use, occupancy, and energy goals, and is often integrated with heating systems via a single heat pump or chiller plant.

Design considerations include maintaining thermal comfort within target ranges, controlling humidity to prevent mold, ensuring adequate indoor air quality, and providing reliable controls and zoning. Energy efficiency is a core objective; high-efficiency equipment, refrigerants with low global warming potential, heat recovery ventilation, and smart controls can reduce consumption. Potential downsides include initial cost, ongoing energy use, maintenance, noise, and risks of overcooling or condensation if not properly designed.

Standards and guidelines, such as ASHRAE 55 and EN 15251, inform acceptable thermal conditions in occupied spaces. Comfortkoeling is distinct from process cooling used in industry and data centers, where temperature control supports production requirements rather than human comfort.
