engineering tasks
Industrial engeneering to bond a absorption cooling machine which was modified to a absorption heat pump.
project chartacteristics
Munich Airport operates an absorption cooling machine. This machine is designed to generate chilled water for air-conditioning by hot water with a temperature level around 95°C.
To improve the efficency of the cogeneration, cooling water from the intercooler and the mixture chillers of the Gas-Otto and Gas-Diesel engines will be feeded to the heat pump. This absorption heat pump raises the temperature level to feed the district heating network at the airport in the heating period.
Absolute priority is to generate chilled water for air-conditioning in summer. To operate the cooling machine as a heat pump is only possible in the heating period.
To realise both functions with one machine it was essential to develop a detail concept for the pipe connections. The development includes the whole pipe network, the connection to the existing pipes and also componets like the plate heat exchangers and the pressure maintenance in the substructure of the network.
In a previous analysis it was determined that the modified absorption cooling machine works with a thermal ratio between 1,69 to 1,74 under design conditions and thermal capacity supply of 2.500 kW.
