3MW HEAT PUMP FOR DISTRICT HEATING
SUSTAINABLE HEATING FOR 800 HOUSEHOLDS
The Danish district heating plant in Frederiks wanted to be less dependent on natural gas and therefore choose two sustainable and energy efficient 1.5MW air-to-water CO2 heat pumps. The two heat pumps will provide sustainable heating for approximately 800 households.
Frederiks started the transition from fossil fuels to sustainable alternatives by installing solar panels as a supplement to natural gas. The solar panels provide approximately 22% of the energy for the needed heating capacity. The two new CO2 heat pumps uses electricity to produce heating, and electricity will thus to a large extend – up to 100 percent – be able to replace natural gas as an energy source.
FACTS
End-user: Frederiks District Heating Plant
Contractor: Aktive Energi Anlæg
Segment: District heating
Background: Become less dependent on natural gas and move towards more sustainable alternatives with CO2 heat pumps
Products: 2 x SteelXL 7+5x0
Specifications:
- 3 MW heating capacity
- Permanent Magnet Motors for maximum energy savings
- Parallel Compressors for maximum energy savings
- High Pressure Ejectors for maximum energy savings
ENERGY EFFICIENT SOLUTION
In addition to being sustainable, the heat pumps are also highly energy efficient. Both heat pumps have the latest technologies with permanent magnet motors, parallel compressors, and high-pressure ejectors for maximum energy savings.
Compared to other natural refrigerants, a CO2 solution is easy and quick to install on-site, as it is fully factory tested. In this way, the right balance between efficiency, investment, and installation costs is achieved.
REUSING WASTE HEAT FROM SOLAR PANELS
The solar panels generate waste heat in the form of lukewarm water (around +20C). Instead of wasting it, one of the two heat pumps re-uses the water to operate the heat pump thereby increasing energy efficiency and overall COP. This means cheaper heating for the 800 households in Frederiks.
