Heating/steam/air-conditioning technology - the latest air conditioning solutions, germ-free and fit for the future, renovation without interrupting operation.

The goal:

In the course of the renovation work, the complete heating system in the 1st and 2nd basement will be renovated without interrupting operation.

This project involves a steam system, pure steam generation, hot water generation, renewal of the heating system, general renovation of the inpatient wing and part of the ventilation systems. 

Our solution:

• A temporary high-speed steam generator and approx.  4,000 m of provisionally laid PE hoses ensure ongoing operation
• Hot water preparation and heating supply is effected via a plate heat exchanger station using steam
• The heating and sanitary pipe network has been replaced by high-quality, hygienic stainless steel piping
• Installation of a central ventilation unit with a total air flow rate of 80,000 m³/h
• All air-handling units now have heat recovery with an efficiency of 75%, two-stage F7/F9 filters, heater, cooler and in some cases steam humidification
• The new outpatient clinic will be equipped with a ventilation system with sound absorbers, fire dampers and volume flow controllers 

The data:

• 2 x Viessmann steam boilers with OWPS system (operation without permanent supervision), steam output 1,200 kg/h per unit
• 2 x Viessmann + Economizer hot water boilers, fuel thermal output 1,900 kW per unit
• Sanitary installation for 270 beds
• Pure steam generator with a steam output of 1,300 kg/h
• Water conditioner for steam, heating and sanitary installations
• Air conditioning system with a total volume flow rate of 80,000 m³/h
