Máša V., Havlásek M., 2016, Integration of Air to Water Heat Pumps into Industrial District Heating Substations, Chemical Engineering Transactions, 52, 739-744.
The paper aims to evaluate a potential of integration of air to water heat pumps in existing district heating substations, especially for supply of heat in an industrial sector. Facts and data from the literary search support the idea that the air source heat pumps (ASHP) should be more often used as a supplementary source of heat in district heating substations. Heat pump is fully integrated in the system and thus efficient for the industrial practice only if the actual return on investment (ROI) is positive. The ROI depends especially on investment cost, average COP, on prices of electrical energy and on the price of heat from district heating. The paper presents a case study of effective integration of 25 kW ASHP into an industrial district heating substation. Sensitivity analysis is conducted to study all the above mentioned aspects of the integration.
