Range of operation:
Due to the advanced vapor injection, the compressor is able to operate at higher high pressure levels. The outlet water temperature increases by 5-10°C when heating at low temperatures: this makes it possible to meet the needs of underfloor heating systems, fan coil units and the latest radiators.
Cooling:
- Water outlet temp. 5~20 °C
- Ambient temp. 5~48 °C
Heating:
- Hot water outlet temp. 30~60 °C
- Ambient temperature -32~48 °C
Advanced vapor injection (EVI)
Optimization:
- Optimum performance is achieved.
- The degree of super cooling is increasing.
- High pressure operation is improved.
- The mass flow rate of the refrigerant through the condenser increases.
- The temperature at the compressor outlet decreases.
- The suction volume of gaseous refrigerant increases.
A pressure-enthalpy diagram describing the advanced steam injection process. Equipped with a compressor with advanced vapor injection (EVI), it provides effective heating at extremely low outdoor air temperatures. This technology also significantly improves the performance of the heat pump, as the pump produces more heat while consuming less power.
Cooling innovations
During cooling operation at an ambient temperature of 45...55°C, cold refrigerant in the vapor state is injected into the compressor, thereby reducing the discharge temperature and facilitating the compressor's working conditions. With EVI technology the main liquid refrigerant flow in the economizer circuit is additionally subcooled, which increases the cooling efficiency of the entire chiller up to 20%.
Optimized heating
Enhanced vapour injection (EVI) increases the refrigerant flow rate and pressure, which means higher heat output and water temperature on the user’s side. At the same time, the increased refrigerant circulation rate results in 20% higher heat output at low temperatures. Heating operation is possible at ambient temperatures down to -26 °C.
