Initial situation

Consumption : 60 000L of domestic hot water per day
Negative cold : R404a system – Cooling capacity = 200 000W & Heat rejection = 304 000W (at -40/+45°C)

Proposal / study

Equipment for negative cold unit : 3x Boostherm 100kW + 1x desuperheater 150kW on positive unit
Installation of 2x desuperheaters on positive refrigeration unit and an air handling unit
Installation of a 15 000L outside stainless steel tank

Forecast return on investment at time of study : 4,3years

Measurements taken

Average energy recovered per day : 2 999kWh/day
Annual energy savings : 959 760kWh/year

Total annual savings : approx. €38 390/year, i.e., equiv. to 201,55 tonnes of CO2/year
