2 System description
2.1 Concept of operation
The Standalone system consists of the following components:
- A Glow-worm Envirosorb 5 heat pump,
- A "Standalone" hydraulic module,
- The Systempro control unit
- A Climapro2 RF wireless programmable room thermostat,
- A wireless photovoltaic outdoor sensor
The following options may be added to the system:
- 2 port valves for zoning,
- A domestic hot water cylinder.
2.1.1 Operating principle in heating
The system is designed to provide a heating need of 6kW max at
the reference temperature.
The heat generator consists of a heat pump and a hydraulic
module equipped with an electric heater. The heat emitters can
also be low temperature (heated fl oor, gentle heat radiators...) or
medium temperature (steel panels...). In order to always obtain
the best comfort/economy trade-off , the module heat pump and/
or electric heater supply the heating installation with hot water
at the temperature necessary to obtain the desired ambient
temperature.
When the power of the heat pump is no longer adequate to
ensure heating, the self-controlled electric heater in the hydraulic
module can operate simultaneously in steps of 2 kW up to a
power of 6 kW (in the case of a heat pump ≤ 5 kW the top-up
power is limited to 4 kW when the heat pump is operating). This
guarantees optimal use of the heat pump while guaranteeing
that the total electrical power consumption will never exceed
6kW. When the heat pump is not operating, the electric heater
can reach a power level of 6kW independent of the outside
temperature conditions.
The changeover point between the heat pump and the electric
heater is managed automatically, depending on the outside and
ambient temperatures. Thus, the system always optimises the
use of the heat pump with respect to the electric top-up heater.
i Avoid programmes with high temperature variations
in the case of power sizing without a signifi cant
margin (based on a calculation with a stabilised
temperature).
