Frequently Asked Questions
A chiller-heater system integrates heat pumps, chiller-heaters, and other hydronic distribution components to provide reliable, energy-efficient, and low-carbon cooling and heating for buildings with hydronic systems. These pre-engineered systems simplify the implementation of electrified HVAC solutions, offering customizable options to meet specific climate and hot water temperature requirements while efficiently managing heat recovery.
The system works by utilizing heat pumps and chiller-heaters machines that are controlled by a building automation system to provide reliable heating and cooling year-round. During colder months, heat pumps transfer heat from the cold outdoor air or recover heat from inside the building to meet the heating loads. In warmer months, the system rejects heat from the building to cool occupants. Additionally, some system variations include thermal energy storage, which allows for the system to store reclaimed energy for when its needed, and a cascade water-to-water heat pump option to boost hot water temperatures to meet the higher heating temperature requirements.
Chiller-Heater Systems apply heat pump equipment and control knowledge to provide cost-effective, energy-efficient cooling and heating for larger buildings, reducing carbon emissions and supporting decarbonization goals.
Thermal energy storage works by storing excess thermal energy collected by the heat pump or reclaimed from the building for use during peak demands. This is achieved through the use of insulated ice tanks called Thermal Battery storage and uses water as a phase change material in order to maximize the energy storage capacity of the tanks.
Chiller-heater systems can be integrated into both new and existing buildings, but the heating temperatures requirements of the existing system need to be evaluated. To assist with retrofit applications, the Hydronic Branch Conductor can be utilized with existing building infrastructure in order to reduce installation costs and minimize disruption. The Conductor efficiently distributes heated or cooled water to dual purpose building coils and maximizes heat pump system efficiency. Additionally, it simplifies the installation process and provides better control and zoning, making the retrofit more affordable and enhancing occupant comfort.
