The article investigates the efficiency of using a heat pump to simultaneously generate heat and cold at a pharmaceutical enterprise in order to reduce energy costs. The proposed scheme, where the source of heat is a refrigeration network with constant parameters, ensures the stability of temperature conditions required for technological processes and product storage. The economic feasibility of using a heat pump in comparison with such a technology as freezing is analyzed at different periods of the day. Particular attention is paid to the automatic regulation of the system through the SCADA system, which minimizes the human factor and guarantees continuous maintenance of the required conditions. Taking into account the requirements of pharmaceutical production, including the need to comply with strict temperature parameters, a water-to-water heat pump was chosen. This scheme allows efficient use of energy between the cooling and heating systems, which ensures stable climate conditions in production and storage facilities. During periods of downtime, the heat pump maintains the required temperature in the refrigeration network, preventing the use of energy-intensive chillers. This solution increases energy efficiency, reduces operating costs, and meets the requirements of good manufacturing practice. Promising areas for further research include the development of algorithms for automatic control of heat pumps, as well as the integration of energy storage systems to improve efficiency under variable load conditions.
