The Norwegian industrial heat pump specialist said its HoegTemp system has a heat supply capacity of 0.2 MW to 5 MW and a coefficient of performance of more than 2 at high lifts.
Norwegian heating specialist Enerin SA has developed an industrial heat pump that can reportedly deliver heat up to 250 C and adapt to different operating conditions.
“The HoegTemp has been tested by leading companies in the pharmaceutical and animal feed sectors, with early adopters GE Healthcare, Pelagia and IVAR IKS Biogas,” a company spokesperson said. pv magazinenoting that it recently raised NOK 180 million ($17.7 million) in a Series A led by Climentum Capital, The Footprint Firm, Johnson Controls and Move Energy, with participation from PSV Hafnium and Momentum.
The system has a heat supply capacity of 0.2 MW to 1 MW, with the size of a 1 MW system being approximately 30 m2 and 10,000 kg. Up to 5 systems can be connected in parallel to achieve a maximum capacity of 5 MW. It uses Helium R704 as working fluid and steam, water or thermal oil as heat carrier.
The heat pump works according to the Stirling cycle, in which a closed single-phase system undergoes compression and expansion by double-acting pistons. Heat exchangers for the heat source and heat sink are integrated into the compressor assembly and form a standard self-contained unit.
The system is electrically powered and has a choice of supply voltage from 400 V to 960 V. It heats a heat transfer circuit which in turn heats a steam generator to generate high-pressure steam. It can also directly heat a water circuit or a thermal oil circuit. The heat transfer circuit can also be integrated with thermal energy storage (TES).
The heat pump has a coefficient of performance of 1.80 to 2.16 and a noise level of approximately 80 dB(A). According to the manufacturer, it automatically adapts to changing operating conditions, such as rapid fluctuations in the temperature of the heat source, while maintaining heating capacity and efficiency. Likewise, if well temperatures need to change due to production requirements or installation changes, the heat pump will reportedly adapt to these new conditions, without any reduction in efficiency.
“The HoegTemp heat pumps have been operating in industrial installations for more than 15,000 hours, with source temperatures from 15 C to 65 C and sink temperatures from 130 C to 200 C,” the spokesperson said. “The Carnot efficiency is in the range of 45% to 60%
increase with increase in temperature. The rated operating range is from -10 C to 250 C and the maximum temperature rise is 260 K.”
The manufacturer also said that the system has an expected lifespan of twenty years and a Technology Readiness Level (TRL) of 9. The TRL measures the maturity of technological components for a system and is based on a scale of one to nine, with nine representing mature technologies for full commercial application.
The fact that Johnson Controls is working with leading European venture capital firms as investors is a strong endorsement of what Enerin is building
