Thermal Battery™ Heat Pump System
Thermal Battery™ Heat Pump System
- Delivers heating and cooling
- Charges and discharges energy like an HVAC "battery"
- Stores and recovers energy instead of rejecting the energy outside
- Includes Trane®-controlled water-cooled chillers, Ice Bank® energy storage tanks and an optional dedicated outdoor air (DOAS) system
- 5 standard modes of operation
(heating – morning warm up, simultaneous heating and
cooling, winter cooling only, summer daytime cooling and summer
night-time ice making)
- Part of the Thermal Battery system portfolio
Decarbonize and Transform to All-Electric
As with the transition from gas-driven to all-electric transportation, the building industry is going through a transformation to carbon-free, all-electric spaces. This transformation is driving new policies and building codes regarding electrification and carbon neutrality. Building electrification, a key decarbonization strategy, requires replacing technologies which run on combustion fuels typically used for space and water heating with technologies that rely on electricity.
How it Works
A building with this system stores and recovers waste energy to deliver heating and cooling. Instead of rejecting energy outside through cooling towers, waste energy is recovered and circulated to the building. This essentially taps into the energy the building already has – energy from the sun the previous day, as well as energy already purchased for lighting, appliances and cooling.
Deliver More Sustainable Heating and Cooling
If you to want to decarbonize and transform your buildings to all electric, we can offer an innovative approach that includes a combination of benefits to reduce carbon footprint, improve energy efficiency and save water.

Like “free cooling”? You’ll love “free heating”
Most modern commercial buildings need some cooling all year. “Free cooling” economizers take in outside air and throw heat out, using new energy in fans. Trane Thermal Battery Storage Source Heat Pump Systems store that heat by melting ice for cooling while using less fan energy. This makes the energy extracted from the building (while cooling) reusable as stored water in the tank. The next time the system needs heating, the heat pump runs with the tank as the energy source. In turn, the energy it extracted from the tank is available when the building next needs cooling. By balancing cooling and heating loads, not simultaneously in real time, but from one day to the next, the system eliminates the need to throw away excess energy.

Maximize benefits by season
This system’s “heat pump” capability allows you to optimize utility costs and energy use by season. In summer, waste energy in the building is rejected through cooling towers. During winter, the waste energy is stored and saved for morning warm-up. The system rejects or stores energy as need during spring and fall. And Trane controls helps automate the variability based on our engineered algorithyms providing you the maximum benefit any time of year!
