Is the refrigerant of the future spelt “propane”?

Propane, first used as a refrigerant over a century ago, has made a comeback as the hottest new refrigerant candidate. It is ozone layer safe, has negligible impact on global warming, and has excellent thermodynamic properties.

The challenges of indoor environment in large spaces

When we discuss the challenges of providing a high quality indoor environment, we often think of residential or office buildings. But there are other types of buildings – ones with large indoor spaces, that present a set of challenges all their own. These challenges, however, can be tackled in …

Why are we moving more water than necessary?

Hydronic distribution for HVAC-systems are too often settled with an outdated technological approach, making the overall system inefficient and distributing more water than is necessary. Big savings can be made in terms of energy consumption by changing the distribution system.

High temperature heat pumps – the heating solution of the future

The EU – and the world, for that matter – is facing a huge challenge from climate change. In the 2009 climate and energy package based on the Kyoto Protocol, the EU set key targets for 2020: 20 percent reduction in greenhouse gas emissions (from 1990 levels), 20 percent of EU energy from …

Optimised water temperature gives lower energy consumption and higher performance

By optimising the inlet water temperature in a waterborne climate system, a number of benefits can be achieved. For example, it is possible to save up to 15% of the energy consumption, in addition you get increased comfort and increased performance of the people in the building.

F-gas restrictions push development of refrigerants

Refrigerants in the form of fluorinated gases (F-gases) potentially spell trouble for global warming, but there is a lot of development in the area.

Why you should consider a 4-pipe system for cooling and heating

A traditional two-pipe system for heating and cooling may not be an optimal solution for buildings with mixed usage that combines, for instance, retails, offices and hotels. Besides, the southward side of the building facing the sun might require cooling at the same time that the northward side, in …

How green is your heat pump?

Right now, large investments are being made in green technology, and the demand for sustainable products is great. But it is not entirely easy to determine which products are truly environmentally friendly, when almost all are marketed as green. This is not least clear in the refrigeration and …

How to optimise your hydronic system

To optimise your hydronic system, you need to balance the work load of both the chillers and the pumps to transfer exactly the right amount of needed energy at the right time throughout the system. This may sound complicated, but there are smart solutions to this that you will learn more about in …
