Optimal energy efficiency for hospitals
The central hospital building is to be replaced by a new building, and the power stations are to be updated to become state-of-the-art. The customer selected an eco-friendly refrigerant whose use will not be restricted in future, e.g. through the F-gas Regulation. The heat pump will guarantee the combined generation of cold and heat in parallel to the two new large boilers, generate thermal heat for heating drinking water.
Climate-friendly QUANTUM chiller of the new generation with refrigerant R-1324ze supplements a hospital´s cooling supply.
10 MW of refrigeration duty servicing Leeds University Hospitals within a district cooling net. All QUANTUM chillers have an integrated Open-Flash-Economiser for best energy efficiency.
The ALBA Group employs around 7,500 people, and is active in Germany, Europe and Asia with its ALBA and Interseroh brands. In 2015 alone, the recycling activities of the ALBA Group saved almost 5.9 million tons of greenhouse gases when compared to primary production, and around 51.8 million tons of primary raw materials.
Combined heat and cold generation in the high-temperature heat pump generates thermal heat of 40/80 °C in parallel to the new large boilers and uses the waste heat directly from the chilled water network for climate application to do so.
The CO2 high-temperature heat pump from ENGIE Refrigeration was chosen because it can supply the required network temperatures, retain a reserve for supply temperatures up to 90 °C, and can also be operated in parallel to a district heat supply.
An entirely new building was erected in Heroldsberg. The heat pump is located in the heating system in the cellar. The main task of the heat pump is to activate the probe array, as server cooling is to a large extent covered by free cooling.
The customer's desire for greater energy efficiency was at the heart of ENGIE Refrigeration's refrigeration concept. The solution is called QUANTUM, because the high energy efficiency at partial load is particularly convincing. In the Schön Klinik Vogtareuth, one QUANTUM chiller runs in regular operation, and another one is switched on as needed.
