Sensible use of the two competences: Heating and cooling.

Electricity, gas and oil prices are continuing to increase rapidly. And even the federal government's relief package nevertheless makes a fundamental rethink necessary. Some 60 percent of energy consumption worldwide can be attributed to heating and cooling. Large-scale energy savings are vital not only because of increasingly scarce resources and soaring energy costs but also to combat climate change. This affects everyone, the private consumer as well as the large energy-intensive company. And it impacts a professional group that would not generally be perceived as being especially energy-intensive, i.e. doctors – and particularly those who use imaging procedures such as MRIs or CTs. The dream of having one's own radiology practice quickly goes up in completely non-climate-neutral smoke in the face of incalculable energy costs.

Lars Hofius, Projects & Solutions Special at Riedel Kooling, has developed a holistic concept that allows the energy efficiency in medical practices, medical centres and small clinics to be significantly increased and operating costs and CO₂ emissions to be drastically reduced.

"The more scans that are performed, the faster the payback on the purchase of an MRI or CT machine. Operation produces a lot of heat. Until now, the diagnostic equipment was simply cooled down; the waste heat was released unused into the environment outside the building.", explains Lars Hofius. "We are changing this. By using water-to-water heat pumps or brine heat pumps, we transfer the waste heat and make it usable. We can therefore heat and air-condition the entire practice building in this way. In a time of advancing climate change, the demand for cooling is rising and even surpassing the demand for heating. Our heat pumps can do both. Heating and cooling. In our model, air-conditioning is provided from above and heating is provided via underfloor heating. This ensures a pleasant indoor climate. In addition, we use the waste heat to prepare domestic hot water, which can be used for showers or therapy pools."

Lars Hofius further elaborates: "This is how we create real added value with one system solution. Even multi-storey medical centres shared by several practices can thus be supplied with energy in a highly efficient manner using a small amount of electrical power, in other words heated, air-conditioned and supplied with domestic hot water.

By way of illustration: Using our heat pump technology, 12 kilowatt hours of heating or cooling energy can be generated with one kilowatt hour of electrical energy. If the building owner opts to extend our system with a photovoltaic installation on the roof, then such a building can be operated self-sufficiently in terms of energy."

"Our 'medical center' concept is another example of our wide-ranging service portfolio for heating & cooling. Our great potential is the merging of both worlds, the complex plant engineering that combines heating, cooling, heat recovery, water management and also other processes."

Lars Hofius stresses: "We always think from our customers' point of view. What does our customer want to achieve in the end? The market wants system solutions with the fewest possible external interfaces that combine all features intelligently and above all in an environmentally friendly way. GDD can offer its customers an all-round package if desired: from precise analysis and consultation to optimisation of the entire plant in a highly efficient system; from design and detailed planning, which also includes identification of the components and services, to consideration of all eligibility criteria and piping construction through to plant engineering in the areas of cooling, heating and water management. We can also take on the role of site manager if required. The entire service is rounded off by customer-centric service and reliable maintenance. This includes monitoring and remote access as well as rapid support via our 24/7 hotline."

By the way: The 'medical center' concept is of course also transferable to other areas, e.g. for industrial or commercial buildings.
