Enhanced Vaporized Injection
In the scroll compressor, wet steam is injected from
the economizer heat exchanger for cooling.
Enhanced Vaporized Injection increases efficiency,
while the power requirement is reduced at the same
time. Thus higher flow temperatures and higher
heating output (especially at low outside tempe-
ratures) are possible. The compression temperature
decreases, increasing the life expectancy of the
compressor.
4.10 Smart Grid Ready
The SG-Ready label is a label for heat pumps, the
controller of which meet the conditions for inclusion in
a future, intelligent power grid
(smart grid
= SG).
Purpose of this function: Load balancing in the elec-
tricity networks of the energy supply companies
(ESCs).
The technique: The energy supply company sends
signals to the heat pump control (by means of a so-
called ripple control receiver) and can thus influence
the operating mode of the heat pump within a defined
range.
This means:
–
At peak loads, the heat pump can be switched off.
–
Surplus electricity can be converted into thermal
energy and stored in the DHW tank or the heating
circuit (e.g. screed of the underfloor heating sys-
tem).
Electricity supplier lock
The ESC may switch off the heat pump for a maxi-
mum of 2 hours (depending on the tariff, up to 3 times
a day) and grants the consumer a reduced rate in
return.
Smart Grid
The ESC cannot switch off the heat pump temporarily
only when needed, but there are four defined ope-
rating modes in the heat pump control, which the
ESC may trigger depending on the power grid load
condition:
Operating state 1 - shut down
–
The heat pump is switched off by the ESC (for a
maximum of 2 hours, equivalent to the current
ESC lock).
Operating state 2 - normal operation
–
The control operates in accordance with the
required temperatures set by the system operator
with regard to room heating and DHW tank
charging.
Operating state 3 - start-up recommendation
–
The DHW tank is charged to its required tem-
perature (if the required temperature has not yet
been reached).
–
The heating circuit is activated
[1]
. The required
flow temperature is increased by an adjustable
value (can be defined for each heating circuit).
[1] if possible due to the settings, e.g. ambient switch off tem-
perature is not reached, ....
Operating state 4 - startup command
–
In this operating state it is possible to set whether
only the compressor or the compressor and the
electric heating element are activated.
–
The DHW tank is charged (within the release
times) by an adjustable value above the required
temperature.
–
The inside setpoint temperature is increased by
an adjustable value (can be defined for each hea-
ting circuit).
