HEAT PUMPS

Heat pumps, the future energy technology in Europe

► Key technology for the future European Energy Goals European Directive, 20/20/20, 2020 20% renewable energies 20% CO2 emissions reduction 20% systems efficiency increasing 20% systems efficiency increasing

Europ. Direct. 2050, Nearly Net Zero Energy Buildings (nZEB)

► Heat pumps, the key technology for heating and cooling. ► Great cost savings, reduction of the energy consuption up to 80% ► Green technology, reduction of CO2 emissions

SLIDE 4

STANDARD HEAT PUMPS TECHNOLOGY

On/off compressors, NO INVERTER, fixed rotation velocity

The Seasonal Performance Factor (SPF) decreases significantly because the heat

pump can’t adapt to the demand variations and the outlet temperature of the heat pump needs to be higher

A buffer tank and at least one additional shunt group (circulation pump +

mixing valve) are needed increasing considerably the cost and the complexity of mixing valve) are needed increasing considerably the cost and the complexity of the installation

Besides the buffer tank means a loss of efficiency throughout the year, since its

temperature is higher (winter) or lower (summer) than the ambient temperature

SLIDE 6

STANDARD HEAT PUMPS TECHNOLOGY

On/off compressors, NO INVERTER, fixed rotation velocity

In many cases an oversizing, and therefore an overcost, of the brine system is

needed since the thermal power needed does not match any commercial value and installing a higher capacity heat pump is required PRACTICAL EXAMPLE PRACTICAL EXAMPLE

Thermal power needed: 11,2 kW Thermal power needed: 11,2 kW Installed power with traditional heat pump (closest commercial value that meets): 13 kW Installed power with ecoGEO heat pump: 11,2 kW Dimensioning of the brine system

1- Installation with traditional heat pump mbrine system = ((13-(13/5))/50)*1000= 208 m 2- Installation with ecoGEO heat pump mbrine system = ((11,2-(11,2/5))/50)*1000= 179 m

mbrine system = ((P-(P/COP))/PEE)*1000 PEE≡ Especific extraction power [W/m]

Cost of the brine system

1- Installation with traditional heat pump Cost= 208 m * 35 €/m= 7.280 € 2- Installation with ecoGEO heat pump Cost= 179 m * 35 €/m= 6.265 €

Overcost in the brine system: 1.015 €

Drilling cost considered : 35 €/m

STANDARD HEAT PUMPS TECHNOLOGY

Thermostatic expansion valves

Much worse control of the refrigerant flow
As a consequence, bigger overheating degrees bigger electrical

consumption for the compression and worse COP

SLIDE 10

STANDARD HEAT PUMPS TECHNOLOGY

Circulation pumps, fixed velocity and less power

Unable to adapt to demand variations bigger electrical consumption
Higher differences of temperature between the inlet and outlet of the heat

exchangers lower evaporation pressure and higher condensation pressure worse COP

STANDARD HEAT PUMPS TECHNOLOGY

Refrigerant R407C

Much more zeotropic than R410A

the temperature is not constant during evaporation and condensation processes lower efficiency in the heat exchangers worse COP

In case of leakage of refrigerant in the circuit to completely drain and refill

the circuit is necessary the circuit is necessary

SLIDE 12

STANDARD HEAT PUMPS TECHNOLOGY

Only 3-phase power supply for higher power models

Less flexibility
To negotiate a new contract with the electric company is necessary

Big peaks of consumption when the compressor starts Big peaks of consumption when the compressor starts (large starting currents)

Oversized electrical installations
Great effect on the SPF
