There are many commercial spaces in need of HVAC systems that supply both hot and cold air at the same time. Places like hospitals, hotels, large office buildings, theatres, museums, indoor sports arenas, and restaurants are just a few examples. While you may assume that these buildings would require separate heaters and air conditioners in order to maintain each room at the desired temperature, there are centralized HVAC systems that can both heat and cool indoor spaces at the same time. 

In the past, buildings that require both heating and cooling would need separate water pumps, a hot water tank or a boiler, and other equipment in order to deliver a steady supply of hot and cold air, and hot and cold water. But now it’s possible to do both with a single, centralized HVAC system designed specifically for your building.

When does a building need simultaneous heating and cooling?

  • Restaurant kitchens and other large commercial kitchens easily get very warm and often need space cooling even during the cold winter months. Anyone who has been in a commercial kitchen knows how warm it gets with multiple ovens, grills, and stove tops operating at full capacity all at once. Air conditioning is required for the comfort of the kitchen staff, while the seating areas may require heat during the colder months to maintain a moderate temperature for customers.
  • Buildings with large data centers generate a lot of heat, and these data centers need to be air conditioned year-round to protect the equipment and prevent it from overheating. Simultaneously, other areas of the building including where the employees sit most likely require heating during the winter.
  • Museums and other buildings that have floor to ceiling windows often require heating and cooling. Glass attracts the cold, so heating may be needed around the perimeter of the room, while areas toward the center of the space may require air conditioning, especially when it’s crowded.

How do these HVAC systems work?

These HVAC systems work by directing the refrigerant to produce both heating and cooling at the same time, then moving it around the building as needed. There are four-pipe HVAC systems that have separate pipes for both cooling and heating and can deliver both simultaneously, and also dehumidifies the air. Using only one return pipe and one supply pipe, water-source heat pumps can deliver both hot and cold air to different areas of a building at the same time. And then there are variable refrigerant flow systems that use refrigerant lines, not piping. These systems are very energy efficient and use outdoor units to heat and cool indoor spaces simultaneously. 

If your building needs a steady supply of both heating and cooling throughout the year, an HVAC system that supplies both is the best choice. Rather than install separate heating and cooling units at multiple spots around your building, you can achieve your heating and cooling needs with a centralized unit that is custom-built for your space. If you’re unsure about which heating and cooling HVAC system is best for you, or you want to replace your current HVAC system, we recommend contacting a professional who can discuss your options with you.
