ThermoCore ECO with Aluminum Condenser
AKG ThermoCore ECO for Ground-Source Heat Pumps in Buildings
The AKG ThermoCore ECO is a new, patented solution specifically developed for use in ground-source heat pumps for building climate control.
This innovative system integrates seven components (evaporator, condenser, expansion valve, receiver, filter, dryer, and internal heat exchanger) into a single compact unit. The condenser can be made of stainless steel or aluminum, depending on specific requirements. The multifunctional refrigerant core, which includes the expansion valve, receiver, filter, dryer, and internal heat exchanger, as well as the evaporator, are made of aluminum.
Thanks to its compact design, the ThermoCore ECO requires minimal installation space within residential heat pumps. Additionally, only two refrigerant lines (suction and discharge lines) are needed to connect to the compressor. This significantly reduces the risk of leaks and shortens installation times. The short refrigerant lines also make the system less susceptible to vibrations and shocks, as confirmed by tests on the vibration test bench in the AKG test laboratory.
The heat exchangers used in the ThermoCore ECO are specifically designed for operation in residential heat pumps using propane (R290) as a refrigerant. They offer high thermal performance while maintaining low pressure losses and requiring only a low refrigerant volume.

AKG and Consolar PVT Solutions:
SOLINK PVT Collectors: Maximum Efficiency for Power and Heat
The SOLINK PVT collectors combine the benefits of photovoltaic (PV) and solar thermal (T) technologies into one system, setting a new standard for sustainable energy supply. Specifically designed for heat pumps, this innovative solution offers an eco-friendly alternative to ground-source and air-source heat pumps, ensuring maximum efficiency and flexibility.
Benefits of SOLINK:
- Dual roof utilization: The air heat exchanger on the underside of the XL PV module provides eight times the heat exchange surface, covering both heat and electricity needs efficiently with minimal roof space.
- Silent operation: SOLINK operates without fans or outdoor units, offering a quiet environment and flexible installation options.
- Maximum efficiency without ground probes: Roof or façade installations are sufficient to efficiently power the heat pump, eliminating the need for costly groundworks.
- Higher energy output: Lower module temperatures lead to up to 10% higher power yields and extended lifespan.
Applications:
- Single and multi-family homes
- Office and commercial buildings
- Municipal buildings
- Low-temperature district heating networks
- Swimming pools
- Replacement or expansion of ground probe fields
This cost-effective solution offers reduced operating costs, comparable investments to ground-source heat pumps with PV systems, and potential funding of up to 70% through Germany’s BEG program.
