Energy Machines™ combined heat pump-and-chillers are the heart of our integrated energy systems, providing properties with simultaneous heating, cooling and domestic hot water.
The integrated system operates in a continuous energy cycle, storing heat energy underground during summer and extracting it during the winter. The configuration may be BTES (Borehole Thermal Energy Storage)-based, where energy is stored in boreholes, or ATES (Aquifer Thermal Energy Storage)-based, where energy is stored within natural underground aquifers.
Replace your conventional energy system with an Energy Machines solution and experience optimal efficiency, comfort, and sustainability – without the expense of our planet. Together, we can make achieving the EU’s 2050 net-zero climate goals a reality.
Our EM1 combined heat pump-and-chiller is up to 35 percent more efficient on an annual basis than a standard heat pump, as cooling units and heat pumps transport more thermal energy than the mechanical energy which is needed to drive the process. Our solutions achieve an efficiency above COP (Coefficient of Performance)** 10 in the production of cooling, heating, and domestic hot water.
** The COP shows the relationship between the energy generated and energy consumed by the system. The higher the COP, the higher the efficiency of the equipment.
Energy Machines™ integrated heat pump-chillers are constructed with the best-available components, which have been selected to achieve optimal energy solutions. Our uniquely high standards ensure the longevity and quality of the integrated systems we build.
Energy Machines™ is the result of several years of research and development. The integrated energy system is based on the same technology as a heat exchanger, efficiently extracting energy from the hot temperature liquid to pre-heat domestic hot water. The result is a high-performance energy exchange.
A heat pump extracts heat from a relatively low-temperature area (e.g. the ground energy from a high temperature area) and adds mechanical energy, transferring it to low-temperature area (for example outdoor air).
The coefficient of performance (COP) is used to compare the performance of cooling units and heat pumps. COP describes the ratio between the transported thermal energy and the added mechanical energy. A heat pump which lifts the thermal energy from 0° C to 60° C has a COP factor of 2,5. This means that the thermal energy is 2,5 times higher than the mechanical energy input. If the heat pump lifts the thermal energy from 0° C to 30° C, it has a COP factor of 5.
Commercial real estate buildings often have a simultaneous demand for heating and cooling. The cooling demand can be satisfied by producing water of 10° C and heat demand by producing water of 40° C. When both the cold and hot sides of a heat exchanger are used at the same time, the amount of the thermal energy doubles in relation to the applied mechanical energy. This gives COP 10.
Our heat pump-based integrated energy system uses sub-cooling technology, resulting in a performance increase of 30-50%, compared to conventional heat pumps. This enhanced performance extends to both hot water production and meeting heat demands, with temperatures reaching between 45 and 60°C.
Your investment in an Energy Machines solution is supported by significant energy and cost savingsr, allowing you to achieve self-sufficiency while reducing your carbon footprint. With our system in place, you no longer have to rely on traditional energy providers. The additional value generated sets our integrated energy system apart as a highly impactful investment.
Energy Machines challenges conventional technology and introduces an integrated energy system as a sustainable solution. Our systems are tailored for each property, efficiently harnessing energy stored in rocks, water, soil, and internal loads (such as heat from server rooms, refrigerated cabinets, chillers, etc.), redirecting it back to the property for heating and cooling. By generating and using energy in these ways, we contribute to a sustainable future for our planet and help you save money.
Energy Machines allows you to sustainably and economically produce heating, cooling, and domestic hot water. Our solution is particularly well-suited for commercial real estate, where there is a continuous need for both heating and cooling throughout the year. Financial calculations based on a standard year with a power requirement of 500 kW for heating and 500 kW for cooling demonstrate a competitive Life Cycle Cost (LCC) calculation. Notably, there are no investment costs for district heating and connection charges (0 SEK), while the investment cost for the Energy Machines' system is approximately 6.5 million SEK
