Description
Summary:	The possibility of utilizing the low-potential heat of the ammonia refrigeration cycle has been shown. The design of an energy-saving heat exchangers network to heat water and air in municipal buildings has been proposed. The possibility of increasing the pressure of ammonia with the purpose of improving the heat recovery in the system and reducing the load of the heating and cooling systems was considered. The minimum temperature difference in the heat exchangers network was selected. The economic efficiency of the retrofit project was estimated.
