AUDAX TOP ErP and Integrated System

voltar.com.ua

4 INTEGRATED SYSTEM FOR AIR CONDITIONING AND D.H.W. PRODUCTION

Comprised of a boiler – solar heating – heat pump and possibly photovoltaic – etc, they are the natural evolution of air-conditioning systems: with very high seasonal eciency, low energy consumption and reduced polluting emissions. ey are engineering solutions that can be perfectly integrated with each other, which allow to attain maximum benet from the various energy production systems on the basis of the respective eciency parameters. For the entire system to operate correctly, Immergas oers a System Manager, able to:

- always make use of the most convenient heat source;

- keep the system performance high in every circumstance;

- control and command the entire system with a unique "brain" (i.e. the System Manager);

- promote heat pump activation with a system that generates electricity from renewable sources.

Basically, the System Manager is a supervisor that can control the entire system). Amongst other things, the following main operations are necessary:

voltar.com.ua

- acquire outdoor temperature (from the external probe, inserted

- set central heating side and cooling side (if provided) climatic

- congure the fuel cost (e.g. methane);

- congure the electric energy cost;

- set the AUDAX TOP ErP minimum integration (cut o) T. e point of economic balance between the gas boiler and the heat pump is a COP value between 2.4 and 2.6 approximately (approximate value referred to methane); this value changes based on the cost of electrical power and gas, in the location

voltar.com.ua

where the system is installed. With sucient Toutdoor to full minCOP economical convenience, or Toutdoor is higher than Tminimum integration (cut o), the heat pump starts and the performance eciency conditions are constantly monitored. On the contrary, if the environmental conditions are such that the AUDAX TOP ErP coecient of performance tends towards lower values than COPmin for economical convenience, or outdoor T is less than minimum integration

(cut o) T, the system Manager starts the boiler (or integrative

resistance).

voltar.com.ua

AUDAX TOP ErP and Integrated System

voltar.com.ua

Each time AUDAX TOP ErP is operating, the Manager enables an additional control, which checks the time it takes the system to reach full operation: when a maximum time is exceeded (can be set dierently between C.H. and D.H.W.) for the heat pump to reach the owT, the boiler or integrative electrical resistance is started. It is also possible to choose the integration operation method (boiler/resistance) between simultaneous or alternative Heat Pump. In all cases where radiant panels are also included for summer cooling, alongside dehumidiers (see previous picture), the System Manager will also monitor the dew point through the installation of room probes (Immergas). anks to this intelligent function the System Manager can increase the ow temperature to the radiant panels by about 1°C (up to a maxT of 18°C - maximum limit of the cooling heat pump), avoiding the phenomenon of condensation on the surface of the structure. is function can only be activated with an Immergas accessory kit that controls humidity. In some cases, for example, the System Manager can turn the heat pump o if the ow temperature to the radiant panels is not suciently corrected.

voltar.com.ua

If on the other hand, there is a high temperature zone in the system, in addition to the low temperature one, it will be served exclusively by the boiler through an accordingly congured dedicated expansion connected to the System Manager. D.H.W: operation: amongst the possible congurations with integrated systems is the option to connect the boiler and AUDAX TOP ErP parallel with the same coil, and use a storage tank probe with one DHW set for the entire storage tank, and set

voltar.com.ua

it in the system's Manager. If the system Manager is connected to the boiler on external probe clamps (pre-set models), if the set DHW temperature is < 50°C, the heat pump starts (always checking the aforesaid convenience); however, if it is > 50°C, AUDAX TOP ErP heats up to 50°C, then the boiler starts; if there is no boiler but there is storage tank integrative electrical resistance, the water is brought to 50°C via the heat pump and AUDAX TOP ErP is then disabled, leaving the resistance to integrate to the pre-set value. In systems where there is a boiler or an integrative electrical resistance on the storage tank, in addition to the heat pump, it is also possible to enable the anti-legionella function.

5 HEAT ADJUSTMENT WITH AUDAX TOP ErP CONTROL PANEL IN STANDALONE APPLICATIONS (SETTING AND LOGIC OPERATION)

e Control Panel (standard supply with AUDAX TOP ErP) enables programming of several operating options and relative

voltar.com.ua

temperature/humidity control of the system.

voltar.com.ua

For example, the Control Panel acquires data regarding outdoor temperature (from the external probe), system ow temperature (regarding the pre-set climatic curve), and also the room's humidity percentage. e standard Control Panel supplied is connected to a specic terminal block on AUDAX TOP ErP, which enables you to program the machine and also functions as a room temperature/ humidity sensor. It also displays the error codes in the event of malfunctions. e room sensor function can be disabled in order to use it only to display the heat pump statuses and leave AUDAX TOP ErP external control management on/o. e user interface is composed of an LCD display, keys and an encoder central knob.

voltar.com.ua

N.B.: With system Manager applications, the Control Panel (standard) can also function as a room temperature/humidity probe of a system's zone.

Place of installation:

e place of installation is very important and must be established by the system's designer or by a specically qualied person, and must consider the technical requirements, standards and laws in force.

• e unit must be installed outdoors only;

• It is recommended to avoid:

- positioning in basement windows

- obstacles or barriers that cause recirculation of exhaust air;

- places with aggressive atmospheres;

- limited spaces or anyhow in places where sound levels from the appliance can be enhanced through reverberations or resonance;

- positioning in corners where there is an accumulation of dust, leaves and anything else that can reduce the appliance's eciency due to blocked passageways;

- prevent exhaust air from the device from coming into the rooms through doors or windows, thus disturbing people;

voltar.com.ua

300

voltar.com.ua

500 500500200

• e appliances must:

- be placed on a level surface that is able to withstand its weight;

- be placed on a slab that is hard enough and which does not transfer any vibrations to the underlying or adjacent rooms;

- use the vibration-dampening supports supplied with the machine.

• If the unit is installed in zones subject to heavy snow, it will

voltar.com.ua

be necessary to raise the machine by at least 200 mm above the normal level reached by the snow, or alternatively use the wall-support bracket (optional).

• If deectors are present to protect the unit against strong winds, these deectors must be studied so as to avoid obstructing the normal air circulation.

NOTE: AUDAX TOP 18-21 ErP is equipped with antifreeze protection comprising an electrical resistance to protect the plate exchanger which is the most critical component with regard to freezing. When the electrical resistance activates so does the pump inside the AUDAX TOP 18-21 ErP, in this way, with power supply voltage, the machine is protected up to -10°C. If AUDAX TOP 18-21 ErP is installed in areas having temperatures below 0 °C, it is recommended to provide special antifreeze systems in order to guarantee the machine's integrity, especially the water-gas heat exchanger, when there is a blackout. For example, insert top quality, non-hazardous antifreeze liquid into the heating system.

In this case, the instructions of the manufacturer of this liquid must be followed scrupulously regarding the percentage necessary

with respect to the minimum temperature at which the system must be kept. An aqueous solution must be made with potential pollution class of water 2 (EN 1717:2002). With no supply voltage and if no antifreeze liquid has been inserted, you must drain the water from the machine. Avoid using automatic lling systems.
