Abstract
Objective. A heat pump integrated into freeze-drying plants increases their energy efficiency, reduces the cost of heating buildings, stabilizes the load on the power grid and brings economic benefits.
Method. The study is based on thermodynamic analysis methods that are used to evaluate the technical characteristics of the freeze-drying plant before and after the introduction of the heat pump.
Result. The technical parameters of the heat pump were analyzed, and the most suitable installation option was selected. There are 2 types of combined schemes with a heat pump for water heating.
Conclusions. The presented installations will make it possible to use excess heat for heating buildings and hot water or reduce the energy consumption of an electric boiler. To create this type of installation, it is necessary to carry out a set of analytical and experimental studies.
