Increasing interest in CO2 refrigeration
|
|
|
It is no longer only the Scandinavian countries, who show interest for refrigeration plants with CO2 as the refrigerant. More supermarket chains in England have also started to install CO2 plants and it is also
spreading to other countries.

Heat Pumps – New Trends in Low Emission Home Heating
|
|
|
by usingrenewable energy sources instead of fossil fuels, wecan help reduce fossil fuel gas emissions. With a heatpump installed we can help reduce our impact onthe environment.
A heatpump collects and extracts the heat from geothermal,aerothermal and hydro-thermal sources, warms itup and “pumps” it into our homes to heat our livingspaces and water.

Seasonal Performances and Compression Technology
|
|
|
In accordance with the logical evolution of the energy consumption of our societies, measurement standards and subsequent labels are coming into a phase of maturity with regard to seasonality.
A theoretical comparison of the different compression technologies applied to a reference installation helps us to make an assessment of the possible benefits of a yearly approach for hot and cold climates. In this example, there is a seasonal COP gap of up to 54%, depending on the compressor technology chosen.

Thermodynamic Limitations and Opportunities for Reaching High Energy-Efficient Refrigeration, Heat Pump and Air Conditioning Systems
|
|
|
In this paper, the theoretical limitations of the Carnot process, as well as the more realistic theoretical approach of the vapour compression refrigeration cycle are examined.
By comparing these theoretical processes to real refrigeration systems, we can identify ways to improve the energy efficiency of the vapour compression cycle. And by evaluating data from existing refrigeration systems, the energy efficiency of current state-of-the-art systems can be assessed.

Danfoss Dedicated Heat Pump Compressor Improves the Seasonal Energy Efficiency up to Almost 10%!
|
|
|
This year Danfoss has launched a new dedicated heat pump compressor – the HHP compressor. The HHP is designed for Air/Water heat pump applications and is suitable for Brine/Water or Water/Water heat pump applications as well.
The dedicated design and optimization of the compressor makes it possible to achieve high energy efficient performance when producing heating or sanitary hot water at very low ambient temperatures.
