FIELD: manufacture of compressors. SUBSTANCE: three additional two-section calorimeters-heaters are connected to high-pressure chladon loop after desuperheating condenser. Inlet branch pipe of first calorimeter-heater is connected to desuperheating condenser and outlet branch pipe is connected to inlet branch pipe of shut-off valves. Outlet branch pipes of valves are connected to oil cooling systems and to compressor suction and discharge heads cooling systems. Outlet branch pipe of oil cooling system is connected to inlet branch pipe of second calorimeter-heater whose outlet branch pipe is connected to condenser of test stand. Inlet branch pipe of third calorimeter-heater is connected to compressor suction and discharge heads cooling system. EFFECT: extended functional capabilities of test stand. 1 dwg
