Heat pump system
4 skids supplied for heat pump in Switzerland (24 MW)
SPRAY CHILLER FOR HEAT PUMP

River, lake water, etc., is cooled by circulating through the tubes.

Tubes material: Stainless Steel, Carbon Steel, Titanium, etc.

Equipment size is reduced, which means savings in installation.

We aim to get a higher COP and EER. Power consumption is much lower.

There is a low NH3 charge, and there is no risk of NH3 leakages in the production areas.

Possibility of supplying the complete skid.

Efficient spray coolers, extremely low ammonia loading, low freezing risk.

Ammonia is the most environmentally friendly refrigerant on the market, with excellent technical performance suitable for large-scale industrial RSW plants. The power consumption of ammonia water RSW is the lowest among all available refrigerants.
Spraying with liquid refrigerant the outer surface of the tubes forms a thin and turbulent protective film. Compared with traditional shell-and-tube chillers, this coverage area can significantly improve heat transfer efficiency.

LARGE SCALE HEAT PUMPS

Large, industrial sized heat pumps are called to play a crucial role into decarbonization of society which must imperatively include a decarbonization of heating & cooling. 

In particular, Water Source Heat Pumps (WSHPs) can be utilized in a variety of applications to displace the burning of fossil fuels for heat generation. Water Source Heat Pumps absorb heat from rivers, lakes, sea water, mineshafts, aquifers, ground, and industrial waste streams to deliver heat at a higher temperature.

INTEGASA’s team has successfully developed a Doble-Tube-Sheet Spray Chiller (Safety Tubes/Double Wall) which vanish any cross contamination of natural resources or industrial waste streams.

The double wall safety tubes feature leakage paths by means of a laser texturizing technique, while insuring a suitable thermal contact between walls. 

As a proof of concept, a water cooler / NH3 – 1.060 kW with only 2K of difference between the water (Lake Geneva) and the evaporation temperature has been delivered to a heat pump in Switzerland. 

The double wall safety tubes were a combination of Carbon Steel on the NH3 side and SS316L (1.4404) on the water side. Other combination of materials is available: CS + Ti; CS + CS, etc.

Rivers and oceans provide the biggest opportunity to decarbonize our big cities.
