Summary

A 250 kilowatt, gas-driven absorption heat pump was installed in the Government Building in Maastricht, The Netherlands. The heat pump uses ammonia-water as the working pair and a process with heat exchange between the generator and the absorber. With the exception of the directly-fired generator, all the heat exchangers are of the plate-fin type. The building, which has a total installed heating capacity of 2,500 kilowatts, is located directly on the bank of the river Maas; low-temperature heat energy is drawn directly from the river water. In installing the heat pump, particular attention was paid to the adaptation of the entire heating system with the objective of keeping the return temperature as low as possible and ensuring that the heat pump can be operated continuously at maximum COP. The heat pump was installed in 1993 and is expected to generate energy savings of approximately 100,000 m3 of gas, thus cutting CO2 output by approximately 175 tons.
