3. The system – summer time
4. Functions in parallel
5. Efficiency
6. Monitoring
7. Examples
cold
medium
hot
By means of air convectors, the
greenhouse air gets heated up.
The heat pump transforms the
heat energy to a usable level
between 25 and 45 °C.
+10 to +12 °C
By means of black
collector pipes (solar
thermal collector in
the pediment of the
greenhouse) heat is
collected by
absorbing sunlight.
Winter
+25 to +45 °C
Floor heating in the
flower / vegetable
beds ensure a very
efficient low-loss
heating of the plants.
If there is the
requirement for
cooling in the
neighborhood
(data centre,
production
process), cold
carrier medium
can be provided
The carrier medium is water
or brine (for frost protection)
well or
water
water from
ground collector
The carrier
medium is
heated up to
an inlet
temperature
of +10 to
+12 °C
Heat can be provided to low temperature consumers
(such as floor heating for homes and office buildings, swimming pools,
or air heating systems in production facilities).
cold
medium
hot
By means of air convectors,
the heat energy gets
removed from the air.
Summer
a) Natural / Passive Cooling or
b) The heat pump transforms the
cooling energy to a higher level.
+10 to +12 °C
By means of black
collector pipes (solar
thermal collector in
the pediment of the
greenhouse) heat is
collected by
absorbing sunlight.
In case of warm days
and cold nights: the
underground could be
used as energy storage.
Cooling can be provided to external
consumers (office building, …).
well or
water
water from
ground collector
The carrier
medium is
reduced to
an inlet
temperature
of +10 to
+12 °C
To improve carbon footprint: Heat can be provided to low temperature
consumers (swimming pools, showers, hot process water).
By switching valves of the heat pump
many of the following functions
can be used in parallel:
- Natural / Passive Cooling (heat pump switched off)
- Active Cooling (heat pump in operation)
- Transformation of specific heat (heat removed from
greenhouse could be used elsewhere)
- Heat recovery on external sources / consumers
- Highly efficiency air conditioning
- Low temperature heat pump (LTHP)
Efficiency:
The term coefficient of performance (COP)
is used to describe the ratio of useful
heat movement to energy input.

According to layout data from Bitzer
Monitoring
The PLC can be equipped with remote
maintenance / diagnosis (teleservice) functions.
