BTC, ground water use for heat pumps condensation

One way to reduce energy consumption is to increase the performance of heat –cold generation systems.

As the cooling requirements are a priority we have analyzed the various cold production systems, especially condensed water.condensed water.

One option discussed was using groundwater of the river Besos with subsequent reinjection.

The study was carried out with the Catalan Water Agency (ACA) and Amphos engineering .

BTC is expected to save almost one and a half million kWh of energy per year (1,445,600kWh) equivalent to the annual energy consumption of 429 homes (])equivalent to the annual energy consumption of 429 homes .(])

The reduction of CO2 emissions is expected to be 963 Tonnes/year, equivalent to the emissions of 669 homes.

Additional investment required to achieve this objective 1 Million Euros (M€) in a total budgetAdditional investment required to achieve this objective, 1 Million Euros (M€) in a total budget of 29M€, is expected to result in an annual saving of 0.25M€. Accounting for financing costs this corresponds to a return rate of almost 20%.
