By integrating a heat pump in the existing energy infrastructure, district heating plants and utility companies as well as companies in need of process cooling are able to achieve higher levels of flexibility in their energy production. This provides their consumers with a less expensive, while still stabile heat supply, while the security of supply is likewise strengthened.

Aalborg CSP’s in-depth understanding of individual energy needs and year-long experience in integrating and combining solutions and technologies allows us to offer turnkey integrated heat pump systems for both district heating and cooling purposes.

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. The heat pump can be used for optimization of the existing heat source. Heat pumps are ideal in co-generation with other renewable energy technologies such as solar heating plants, biomass boilers and Pit Thermal Energy Storage (PTES) systems.

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.

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 and renewable energy sources and natural refrigerants. For enviromental and safety reasons, we have deselected to make use of synthetic, fossil and higly explosive refrigerants.
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.
