MATHEMATICAL DESCRIPTION OF THEFUEL‐FREE PLANTS GENERATE ELECTRICITY BASED ON ONE‐AND TWO‐STAGE EXPANDER‐GENERATOR UNITS AND HEAT PUMP SYSTEMS VAPOR COMPRESSION AND AIR TYPE
One of the most effective technologies to reduce the consumption of fuel and energy resources is an expander‐generator technology. In combination with heat pump units (HPU) expander‐generator sets (DHA) allow creating highly efficient power generating systems that are capable of generating electricity with‐ out burning fuel.
