GENERAL FEATURES

Unit description

This series of air-water heat pumps satisfies the heating, cooling and domestic hot water production requirements of residential plants of small and medium size.

All the units are suitable for splitted installation (indoor unit and outdoor unit connected through refrigerant pipes) and can be applied to fan coil plants, radiant floor plants and high efficiency radiators plants.

The control system allows to manage not only the refrigerant circuit but the whole plant with the possibility to choose different solutions both for the heating and cooling plant and for the domestic hot water management. The possibility of solar panels or other heating sources integration is also available.

The heating function optimizes the flow water temperature according both to the ambient temperature and to the outdoor temperature through climatic curves adaptable to the building features. It’s possible to manage a storage tank and two independent circuits (a direct one and a mixed one).

The domestic hot water management allows to control the three way valve, the storage tank and the anti-legionella cycles (if necessary).

The cooling function can be realized through “active cooling” (refrigerant circuit inversion). When the unit is used in radiant floor plants, to avoid condensate generation, a room humidity sensor can be installed.

The internal programmer clock allows to define different daily switching programs for heating, cooling and domestic hot water production.

The heat pump is composed by an indoor unit (motocondensing unit) containing the hydraulic circuit, the electrical board, the compressor and a part of the refrigerant circuit and an outdoor unit (remote evaporator).

The refrigerant circuit, contained in an extractable box to simplify the maintenance operations, is equipped with rotary compressor mounted on damper supports, brazed plate heat exchanger, thermostatic expansion valve and reverse cycle valve and liquid receiver.

The circuit is protected by high and low pressure switches and flow switches on the plate heat exchanger.

The plate heat exchanger and all the hydraulic pipes are thermally insulated to avoid condensate generation and to reduce thermal losses.

The outdoor structure of the indoor unit and the refrigerant circuit box are both thermally and acoustically insulated in order to create a double wall against sound propagation and to allow the installation in domestic places.

To avoid vibration propagation towards the hydraulic circuit the refrigerant circuit box is placed on damper supports and the connection pipes are flexible.

The outdoor unit is composed by finned coil made of copper pipes and aluminium louvered fins and axial fan with safety protection grilles. The fan, supplied with DC motor and electronic rotational speed control, guarantees high efficiency and low noise in all the operating conditions.

All the units are supplied with an outdoor temperature sensor in order to realize the climatic control.

All the units are accurately built and individually tested in the factory. Only electric, hydraulic and refrigerant (between indoor and outdoor units) connections are required for installation.

The heat exchangers on the plant side (2) is a brazed stainless steel plate heat exchanger, properly insulated to avoid condensate generation and to minimize thermal losses, and protected by a flow switch that detects whatever water flow lack. The source side heat exchanger (3) is a finned coil realized with grooved copper pipes and hydrophilic aluminium fins with waved profile to increase the heat exchange coefficient.

A tray is placed under the coil to collect the condensate generated in heating mode. The expansion device (4), an electronic expansion valve, allows the unit to adjust itself to the different operating conditions keeping steady the set superheating.

GENERAL FEATURES

Control system

The microprocessor controller is able to manage not only the unit itself but also all that components of the plant which allow to realize a complete system.

The main functions of the control system are :

- room temperature control according to the outdoor temperature (climatic control)

- domestic hot water production (management of 3 way valve, storage tank, anti legionella cycles…)

- management of a heating and/or cooling mixed circuit (pump and 3 way mixing valve)

- management of a heating direct circuit (only pump)

- management of a storage tank for heating and/or cooling

- management of electrical heaters for heating and domestic hot water (3 steps logic)

- solar panels integration

- room humidity control for cooling with radiant systems

- internal programmer clock (for heating, cooling and domestic hot water)

- digital input for electrical energy low tariff

- alarm memory management and diagnostic

- compressor and pump operating hour counter

- possibility to manage more units in cascade (maximum 16)

Besides the standard user interface present on all the units, wired or wireless remote thermostats are available which allow to control all the operating parameters of the unit and to acquire the temperature in the different zones in order to realize a more precise and comfortable control.

The unit controller is able to manage a lot of different plant solutions enabling automatically the necessary control algorythms according to the components which have been connected.

The management of such components is possible through additional expansion modules which communicate with the unit by means of an internal bus and provide all the inputs and outputs required to fulfil a complete system.

FS

FS

The controller is able to manage up to two zones in heating

(one by means of a mixed circuit and the other by means of a direct circuit) and one zone in cooling (by means of a mixed circuit).

It’s possible to realize more complex plants connecting to the heat pump controller further expansion modules in order to extend without limits the number of zones to be managed.

For each zone the following parameters can be set :

- set point

- daily or weekly operating time table

- climatic control curve

- room control sensor : it can be in common with the other zones or independent (in that case it’s necessary to install an additional room thermostat)
