The 4-pipe units can control a high and low temperature circuit simultaneously.
The speed of the compressor, fan and circulators is continuously regulated by the control unit.
The DURAN units are characterised by high efficiency and the integrated management of the circulator that allows high temperature water to be produced via a heat exchanger specific for DHW production.
On the system side heat exchanger the unit is able to produce hot or cold water to meet the building's seasonal heating and cooling requirements.
On the heat exchanger for the production of domestic hot water, the unit produces high temperature water to send to an external storage tank, which has been chosen and sized according to the requirements of the system.
Seasonal modes
The unit operates in a different way according to the season:
The system switches between the various operating modes (within a season) automatically by reading the temperature probes and the programmed set points. Switching times and logics are designed to ensure maximum system efficiency and reliability.
This configuration must be associated with a suitably sized boiler in which to store the high temperature water. The upper part of the boiler must be fitted with a thermowell in which to insert the hot water probe, through which the unit controller monitors whether hot water has to be produced.
Summer operation
There are three summer operating modes:
- Chiller mode
The unit produces only chilled water for the cooling system. - Chiller mode with the simultaneous production of domestic hot water
The unit produces chilled water for the cooling system and domestic hot water at the same time. Full power is recovered for the production of domestic hot water. - Heat pump mode for the production of domestic hot water
If there is no cold load, and on request by the hot water probe, the unit heats the water in the water storage tank using the finned pack coil as an evaporator. The use of warm outside air as a heat source guarantees extremely high COP levels.
Winter operation
There are three winter operating modes:
- Heat pump mode for heating
The unit produces hot water at the system side heat exchanger for heating. - Heat pump mode for domestic hot water
High temperature hot water is produced at the heat exchanger connected to the domestic hot water storage tank. - Heat pump mode with the simultaneous production of domestic hot water
DHW is produced at the same time as hot water for the heating system by desuperheating the gas R410a while maintaining a high COP.
Technical specifications
Air-water heat pump in vertical monobloc version for installation:
- Outdoors with EC axial fan
Multi-purpose monobloc unit equipped with Twin Rotary Inverter compressor boasting an advanced design and a high COP.
The unit allows the indoor dimensions to be reduced to the minimum as it is equipped with a 120 l stainless steel boiler and a 35 l stainless steel buffer tank for the heating system. Designed to be installed in the most difficult places (indoors and outdoors), it can also be installed very close to a wall and can be connected on three sides (back and sides). The heat source is the outdoor air up to a minimum of
-15°C. Low noise is guaranteed by an intelligent control system that regulates the speed of the compressor and fan according to actual requirements. In addition, the use of anti-vibration mountings for the compressor and multi-layer noise insulation on the casing mean noise is reduced to a minimum.
Controller
The control unit is state-of-the-art and can be combined with a highly intuitive remote controller with which all the operating parameters, set points and usage settings can be controlled. The storage tank is charged at a set point for DHW and with a heating or cooling curve for the heating / cooling side.
Structure
The units are made of powder coated hot-dip galvanised sheet metal and have a high resistance to weathering; the structure is self-supporting with removable panels to make inspection and maintenance easer.
Cooling circuit
The refrigerant gas used is R410A. The unit is fitted with inspection ports to enable technicians to check that the cooling circuit is operating correctly.
.
Heat exchangers
The source side heat exchangers are made of copper pipes and aluminium fins coated with hydrophilic paint that encourages water run-off. The user side braze-welded stainless steel plate exchanger allows the amount of refrigerant gas to be reduced to the minimum and maximise the efficiency due to the large heat exchange surface.
Internal components
The unit contains a 120 l stainless steel boiler with a safety heating element and a 40 l stainless steel buffer tank for the heating system. The exchange takes place in a stainless steel coil inside the DHW boiler and through a high-quality stainless steel braze-welded plate heat exchanger.
Components included:
- Primary system circulator
- Differential flow switch
- System safety valves and DHW
- Expansion vessels
- Heating element with safety thermostat
- Protection anode
Accessories that can be installed inside the machine:
- Anti-scald thermostatic mixing valve
- Magnetic dirt separator
- Secondary circulator
Fan
The brushless EC axial fan has been designed to reduce noise to a minimum and to maximise efficiency. The speed of rotation is continuously regulated by the control unit.
Control and protection
The unit is equipped with a series of alarms designed to protect it from faults. These are managed entirely by the control unit that makes them available and accessible. It is also possible to access the controller via the control unit if you need to make any adjustments.
Testing
All units are fully assembled and wired. They are inspected to high standards, undergo leak and vacuum cycle tests, and are filled with an eco-friendly refrigerant. They undergo a complete functional test before being delivered. All units comply with European Directives and have a CE marking and relative certificate of conformity.
Auxiliary controls
Other auxiliary controls are possible with HP1 - GOLD system expansion, an expansion module that connects as a BUS accessory to the existing control unit and allows important and innovative functions to be added that are useful for more complex systems:
- DPAC: a 0-10V input that regulates the power used by the heat pump according to the instantaneous availability of the solar energy system. This is an extremely innovative logic developed by Thermics Energie: when the heat pump is set to "ECO" mode, it operates according to the availability of energy and its wide modulation range means that it will avoid drawing electricity from other sources.
- MIX1: available for the management of a general system mixed unit with 0-10V signal.
- INFO SEASON: an outlet that alerts the rest of the season change system.
- HEAT TRANSF: a setting that specifies the logics used for heat transfer through a plate heat exchanger or a secondary transfer boiler.
- HYBRID: relay activation of heating integration using a second source both on the DHW side and on the heating side.
Multiple units can also be controlled with HP2 – expansion module for cascade control. To extend the life of the heat pumps, the controller can intelligently control the rotation of the units in the case of partial load.
Remote Brain
To control all heat pump activities remotely.
- Remote Brain is a simple and inexpensive system for monitoring residential installations that allows you to switch on Thermics Energie heat pumps, control their respective temperatures, monitor their operation and to provide the heating comfort requirements of the home directly from any device, both inside and outside the home. This innovative system means that all the main terminal units for HVAC and the production of domestic hot water are constantly monitored, to enable the heat pump to be used in the most efficient way and to obtain maximum savings in terms of energy and cost.
- The information is transmitted locally using Wireless technology to Tablets, Smartphones and PCs directly from the ADSL router, which uploads it to a data collection CLOUD. This means that the data is always up to date and can be used at any time and on any device, wherever you are. The system also allows you to report heat pump malfunctions, meaning that trained technicians can take the appropriate action quickly. They will immediately know the reason for the malfunction and be able to restore correct operation of the heat pump rapidly.
- Remote Brain has an annual charge for maintaining the service and its functions (see t-Service).
