Figure 1: HTHP Equipped with High Precision Double Hinged Arc Vane Compressor

Summary of technology

• At the heart of the HTHP, there is a novel double hinged arc vane compressor (Fig.1) driven by a vertically placed electrical motor. Main features are listed below.
• Closed loop HTHP is equipped with oil-to-refrigerant evaporator and condenser (Fig.2);
• Compressor eccentric shaft (5mm) allows for low torque arm and as such, ensures the lowest input shaft power in its class,
• Double hinges of the arc vane compressor fully eliminate sliding frictions that are inherently present in swing-vane type and other spring-vane type commercial rolling piston compressors;
• HTHP part load capabilities range from 20% up to 100% thanks to electrical inverter motor;
• The HTHP cycle is charging a high temperature thermal energy storage tank for commercial applications;
• We provide low-cost decarbonization solution for revalorization of low-grade heat from:
  • Air heat source (-10°C to 100°C)
  • Geothermal heat sources (10°C to 130°C),
• Each HTHP has a maximum installed thermal power of 1 MW. Each rack is combining standard compressors in series, each contributing to a rated heat pump power of 25kWth, 75kWth, and 125kWth;
• Lubrication oil is PAG68 and oil quantity is 0.75 Lt;
• No oil pump is needed;
• Development status has now reached TRL6 at the factory test bench;

• The Heat Transfer Fluid (HTF) on the sink and source sides is mineral-based Renotherm 320. Refrigerant-to-HTF heat transfer in the evaporator and condenser are achieved through 13.05 m2 of heat transfer surfaces and 29 m of finned copper piping. Hot oil circulation pumps move 100 liters of HTF within the condenser to the Thermal Energy Storage (TES).
