External thermal energy
Heating and cooling are responsible for half of Europe’s energy demand..
..RES directive creates the conditions for the development and for the use of thermal tecnologies in Europe

External thermal energy
“Environmental thermal energy”: thermal energy is always stored in external air, water and ground.”
Only heat pumps technology allows to take advantage of this thermal energy
martedì 17 gennaio 2012
Technical training - part A 6
RES DIRECTIVE
For the purposes of the directive the following definitions apply:
"energy from renewable sources" means energy from renewable non-fossil sources, namely wind, solar, aerothermal, geothermal, hydrothermal and ocean energy, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases.
"aerothermal energy" means energy stored in the form of heat in the ambient air
"geothermal energy" means energy stored in the form of heat beneath the surface of solid earth
"hydrothermal energy" means energy stored in the form of heat in surface water
martedì 17 gennaio 2012
Technical training - part A 7
The amount of aerothermal, geothermal or
hydrothermal energy captured by heat pumps is to
be considered energy form renewable sources for
the purposes of the RES directive
(and has to be calculated in accordance to the same directive)

HEAT PUMPS AND RENEWABLE ENERGIESThe heat pumps move renewable thermal energy from external
sources to heating plants and viceversa

How heat pumps work?
martedì 17 gennaio 2012
Technical training - part A 10
Heat pump technology
Heat pumps are machines that transfer thermal energy
from a lower temperature location, so called “source”,
to a higher temperature location, so called “heat sink”.

Heat pumps/refrigerators
move thermal energy
thanks to a working fluid, called refrigerant, operating in
a thermodynamic cycle

To know the energy and pressure level of the refrigerant during the cycle we shall know how reading the pressure-enthalpy graph
Enthalpy is used for heat energy and is measured in kilojoules/kilogram

Heat pump technology
EvaporationRefrigerant vaporises in order to absorb
heat energy from the source.
SuperheatThe superheating of the refrigerant within the
evaporator is essential to protect the compressor from taking in liquid refrigerant.
martedì 17 gennaio 2012
Technical training - part A 19
Heat pump technology
CompressionThe compressor raises the pressure and
temperayure level of the superheated vapour bringing it to the condenser
The refrigerant takes energy during this process and this is termed Heat of Compression
martedì 17 gennaio 2012
Technical training - part A 20
Heat pump technology
CondensationThe condenser removes energy from the refrigerant and reject this to the
lower temperature sink
Heat rejected in the condenser is Heat received in the evaporator
+Heat gained in the compressor
martedì 17 gennaio 2012
Technical training - part A 21
Heat pump technology
ExpansionHigh pressure and subcooled
refrigerant via the expansion device returns to the evaporator coil.
The expansion device (thermostatic or electronic valve) is a very important component! It has a sensor attached to the external surface of the refrigerant pipe leaving the evaporator coil: the valve ensures that
the evaporator is adequately supplied with liquid according with the istantaneous cooling load.

Refrigerants
Refrigerants are riquired to have some important properties:
- high critical tempertaure
- high heat of vaporization (high cooling effect)
- stable chemical composition
- high heat exchange capacity

Aerothermal energy
The temperature range of an air sourced machine goes from -20°C to 40°C according to its working range.
The extnarl heat exchanger extract/reject heat from/to external air. Air flows through the coil thancks to one or more fans.

Geothermal energy
- In the first layer among the surface and 15 metres depth, ground temperature changes during the year- with encreasing depth, ground temperature remains constant and begins to rise after 100 metres depth

Electronic management of defrosting cycles
- evaporator temperature and presure
Fewer the defrosting cycles higher is the performance of the heat pump!
- frequency of defrosting cycles
The time occuring from a defrosting to another is not fixed but depends on exchange capacity of the evaporator: a counter accelerates the defrosting start if the capacity gets worse or slows it down.
The advanced electronics ensures to control continuosly the heat exchange capacity of the avaporator detecting:
