Agenda

• What's worth for a HP success?

• Vilter Single Screw short description

• If there is hot, there is certainly also cold

• Be opportunistic in your revamping

• Be Creative and make new business Model

• Optimise your existing Installation

• Conclusions

High Capacity

Working pressure for Heat Pump Application

Balanced screw allows casing material for higher working pressure (Cast iron, Ductile Iron, Cast Steel)


If there is hot, there is certainly also cold


Be opportunistic in your revamping

• Clean In Place process

• Cheese ripening rooms

• General cleaning process need

• Reduce energy costs

• Heat Recovery from cooling process

Reduce CO2 emissions generated by

gas and fuel combustion

• Replace old cooling installation

Make new Business Model

Norway’s Dairy Cooperative Tine

THE DAIRY JAEREN PLANT –

200 Millions liters milk processed per year

Make new Business Model

Norway’s Dairy Cooperative Tine

Cooled loop @ -2°C


production for process cooling

Hot water @ 58°C



• Greenhouse heating


• Reduce CO2 emissions by 30 - 40 %

with this new dairy

• Sell heat to Industrial Greenhouse

close to the dairy

• 5400 kW @ -5°C required refrigeration duty,

Condensing +37ºC

• 6900 kW @ 58°C water required heating duty

• 7200 kW @ 73°C water required heating duty


Sell the heat to the Greenhouse next door ? Why not?

58°C

Plans for connecting a local business estate to the heating

network and increase the supply temperature to 73°C

within the next couple of years

First step to a Greenhouse

Second step to local business place

Added revenues, new business


How? Two stage Installation

3 low stage (VSS-1851 ) and 2 high stage

compressors units (VSSH-791)

Payback of the plant of less than 2.5 years.

Cooling Capacity 5400 kW @ -5°C/+37ºC

Conclusions

• Combined heating and cooling with an ammonia heat pump is a very

attractive solution among existing only heating system.

• This allows savings not only for heating cost but also

• On the total cost of energy per units manufactured

• In term of CO2 emissions,

• Low Ammonia charge (For those who would be afraid of this)

• In term water consumption

• For the future, F-Gas regulation in Europe opens large opportunities

in the replacement of existing HFC installations.

• Combined heating and cooling can be applied on any industrial

process requiring cooling and heating on different steps in their

manufacturing process.
