Thermal distillation is one of the most common and reliable methods of water treatment, but its use is constrained by high energy-intensity. There are processes where thermal distillation is one of the main methods of liquid purification, for example for getting water for medical purposes. The most effective way of reducing distillate production cost is use of thermal transformers that allow recovery and regeneration of heat of liquid phase transformations. The results of mathematical-experimental investigations of high-temperature vapor-compression heat pump distiller using the natural working substance n-heptane are presented. The possibility of using standard leakproof small-capacity refrigeration compressor as the main means of pressure elevation and transfer of vapors of the working substance as a component of the heat pump distiller is shown. The efficiency and energy consumption data for the proposed equipment are obtained.
