Heat pump integration for optimum energy utilization

By integrating a heat pump in a district heating supply, district heating plants and utility companies are able to achieve higher levels of flexibility in their energy production thereby providing the consumers with a less expensive, while still stabile heat supply.

Aalborg CSP’s in-depth understanding of individual energy needs and year-long experience in integrating and combining solutions and technologies to propose the most value-adding solution allows us to offer turnkey integrated heat pump systems with the aim of lowering the cost of district heating.

Increased system flexibility with sector coupling

Integrating a heat pump with other heat sources such as e.g. solar heating- and biomass plants can prove profitable in terms of improved efficiency and flexibility.

At Aalborg CSP we are not obliged to make use of one specific heat pump technology. Instead, we support our clients in finding the most suitable heat pump for the individual project. We work with a wide variety of natural heat sources (outdoor air, excess industrial heat, biomass, waste water, sea water etc.) and refrigerants (Ammonia and CO2). By choosing the right type of heat pump, an optimization of the heat production can be obtained, while still reducing the electricity consumption in order to ultimately achieve a lower price on heat; which is less sensitive to fluctuating electricity prices.  

Optimized efficency with heat pump integration

Depending on the individual energy requirement, a heat pump can act as an independent stand-alone unit or as an add-on to an existing heat source, such as a solar heating- or biomass plant. District heating supplies with an already existing heat source can benefit from heat pump integration as a heat pump can be used for optimization of the existing heat source.

By integrating a heat pump in e.g. a solar heating plant, it is possible to obtain and utilize valuable synergies between natural energy sources and thereby optimize both the flexibility and efficiency of the heat supply. In such combination plants, waste heat from transformers and engines is utilized while integrating solar heat. This increases the yield of solar heat, while the COP (Coefficient Of Performance) is likewise improved. Calculations show that the yield from an existing solar heating plant can be increased significantly by 8% to 28% through intelligent integration of a solar and heat pump solution.
