Procurement of a heat pump system with CO2 as working medium

Text automatically translated in your browsing language

The DLR Institute of Low-CO2 Industrial Processes intends to procure a heat pump system with CO2 as a working medium. This system is then expanded to test various new components (heat exchangers, compressors, ejectors and expanders). Optical measurements are also carried out, which require the greatest possible oil-free CO2 as well as low vibration values. In addition to the actual system itself, the secondary circuits must also be designed, supplied and put into operation. Excess energy input must be delivered to the environment by means of a recooler. The engineering and construction of the entire plant, including the control and regulation system, based on programmable logic controllers (PLCs) and the necessary supply and disposal systems for the plant peripherals, must be carried out by the contractor (AN). The client (AG) provides a procedural concept on the basis of which the plant must be fully designed and built. The place of delivery is the DLR project hall in Cottbus (Gerhart-Hauptmann-Straße 15, 03044 Cottbus). Further important information can be found in the procurement documents. DLR intends to finance the procurement with third-party funding and has submitted a funding application for this, the decision of which is still pending. Although DLR is optimistic that the application will be approved, the call for tenders is subject to funding. If the application is rejected and alternative funding cannot be obtained, the call for tenders must be terminated without result. In this case, too, tenderers cannot be reimbursed for any costs incurred by them as a result of participating in the invitation to tender. +++
