Source and Need

Sources Heat Pump Applications

The most interesting is when the cooling of the heat

source is part of the process !

Be opportunistic in your revamping

The Dairy Vire Plant

Chilled water @ 1°C

Heat Rejected by chilled water

production for process cooling

Hot water @ 58°C

• 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

production for process cooling

Hot water @ 58°C

• Clean In Place process

• General cleaning process need

• Greenhouse heating

• Heat Recovery from cooling process

• 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

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.
