Future-proof district supply thanks to our SPECTRUM water heat pump
A SPECTRUM Water heat pump and two QUANTUM Air chillers cover the cooling and heating requirements of a large service and hotel complex in Bordeaux all year round - and guarantee a consistently efficient district supply.
-
The SPECTRUM Water heat pump with an output of one megawatt of heating and 740 kilowatts of cooling independently manages the district supply in Bordeaux for most of the year. In summer, two QUANTUM Air chillers, each with an output of one megawatt, generate additional cooling for the building complex.

The SPECTRUM Water heat pump boasts industry-leading seasonal efficiency values (heating SCOP 45/55 to 6.11; cooling SEER to 8.26), especially at partial load, which accounts for around 75 percent of the operating time.
Future security, independence from fluctuating oil and gas prices, and reduced indirect emissions through high seasonal efficiency (heating SCOP 45/55 to 6.11; cooling SEER to 8.26) and the low-GWP refrigerant R-1234ze – these are the goals that the operators of a 40,000 square meter service and hotel complex near Bordeaux airport are striving for when it comes to district supply. The customer also attaches great importance to high efficiency, low noise emissions and absolute operational reliability of the cooling and heating application for its accommodation. ENGIE Refrigeration provided the right solution for all these requirements: the SPECTRUM water heat pump with an output of one megawatt of heat and 740 kilowatts of cooling. This enables the system to supply almost the entire district. The heat pump feeds into a heating and cooling network that generates hot water (55 degrees Celsius) for space heating and cold water (7 degrees Celsius) for space cooling for the building complex in winter. This is achieved by the integrated hydraulic circuit. Two QUANTUM Air chillers, each with a cooling capacity of one megawatt, are only available for the additional cooling requirements in summer.
One heat pump, many advantages
Thanks to the oil-free and magnetic bearing of the compressor shaft, the SPECTRUM Water heat pump impresses with its consistent efficiency in district supply. Its high seasonal efficiency values (heating SCOP 45/55 to 6.11; cooling SEER to 8.26), particularly at partial load, which accounts for around 75 percent of the operating time and result in low operating costs. Thanks to the low-GWP refrigerant R-1234ze, the SPECTRUM Water heat pump produces significantly reduced direct greenhouse gas emissions compared to conventional high-GWP refrigerants – and is therefore well suited to the BREEAM sustainability certification of the building complex. In addition, the waste heat in chiller mode is used to regenerate the probe field, among other things, so that the primary energy from the ground is used as a thermal storage medium as part of the district supply. The compact, lightweight and simple machine design reduces installation and maintenance costs and also saves important space. The pleasant atmosphere in the district also remains undisturbed at all times: thanks to its low noise level, the heat pump generates very reduced noise emissions. In short, our SPECTRUM is the ideal solution for district heating.

Industrial heat pump enables efficient heat supply at the chemical park
A chemical industry site is modernising its heat supply to optimise energy use. Previously, heating was provided via a central steam distribution system with high system temperatures and a correspondingly high energy requirement. The aim of the project is to gradually adapt the heat supply whilst continuing to make reliable use of the existing infrastructure. The project is being carried out in collaboration with the Building Technologies division of ENGIE Deutschland GmbH.
Retrofit for water-cooled QUANTUM chillers at the airport
ENGIE Refrigeration is modernising two existing QUANTUM chillers at an airport in Bavaria as part of a retrofit project. The modernisation includes compressor replacement, a new control cabinet, an upgrade of the Siemens PLC and the conversion to the R-513A refrigerant. These measures update key system components without requiring structural alterations to the building or infrastructure.
