2.4 Operating principle

The equipment belonging to the 1.9 kW and 2.9 kW series is capable of producing domestic hot water mainly by using heat pump technology. A heat pump is capable of transferring thermal energy from a low temperature source to another with a higher temperature and vice versa (heat exchangers).

The equipment uses a water circuit consisting of a compressor, an evaporator, a condenser and a lamination valve; a liquid/gas coolant flows inside this circuit (see paragraph 4.6).

The compressor creates a difference in pressure inside the circuit that allows a thermodynamic cycle to be obtained: this sucks the coolant fluid in through an evaporator, where the fluid itself evaporates at a low pressure by absorbing heat, it is compressed and driven towards the condenser where the fluid condenses at a high pressure releasing the absorbed heat. After the condenser, the fluid passes through the so-called “lamination valve” and by losing pressure and the temperature starts to vaporise, it re-enters the evaporator and the cycle starts all over again.

1 – Operating principle

The operating principle of the equipment is as follows (Fig. 1):

I-II: The coolant fluid sucked in by the compressor flows inside the evaporator and while it evaporates, it absorbs the “ecological” heat given by the air.

At the same time, the ambient air is sucked in by the equipment by a fan; the air loses it heat by passing over the finned-tube battery of the evaporator;

II-III: The coolant gas passes inside the compressor and it under goes an increase in pressure that causes a rise in temperature; transforming this into superheated steam;

III-IV: Inside the condenser, the coolant gas releases its heat to the water inside the tank (boiler). This exchange process makes it possible for the coolant to pass from superheated steam to a liquid state by condensing at a constant pressure and undergoing a reduction in temperature;

IV-I: The liquid coolant passes through the lamination valve, it undergoes a sudden drop in both pressure and temperature and it partially vaporises bringing pressure and temperature back to the initial conditions. The thermodynamic cycle can begin.

2.5 Available versions and configurations

The heat pump is available, in relation to the thermal power (1.9 kW version), which can be set up in different configurations, depending on the possible integrations with other heating sources (e.g. solar thermal, biomass power, etc.).

conditions

One of the peculiarities of the heat pump heating system is represented by the fact that these units cause a considerable reduction of the air temperature that is generally ejected from inside the home. Apart from being colder than the ambient air, the exhaust air is also completely dehumidified; for this reason, it is possible to allow the air to flow back into the home in order to cool specific environments or rooms during the summer.

Installation consists of the splitting of the discharge pipe to which two shutters are applied (“A” and ”B”) with the aim of directing the air flow either towards the inside (Fig. 5a) or the outside of the home (Fig. 5b).

x Digital 2: Input from photovoltaic system.

When a free contact is established between terminals 31 and 32 (cable: green/white) and the heat pump reaches the SP5 temperature (default setting 62°C), the hot water nominal temperature is raised by 7°C. It is possible to change the SP6 parameter (e.g.: raising the temperature from 62°C to 70°C) so that, if there is enough PV electrical energy, the heat drop from 62°C to 70°C is made by the immersion electric heating element (if SP6 is the same as SP5, the electric heating element will never activate).

6.6.1.1 Remote link mode

As regards links to digital inputs, the equipment is provided with an additional 4-core cable that has already been linked to circuit board of the user interface (placed inside the equipment Fig. 14). The remote links to any energy systems must be carried out by a qualified installer (junction boxes, terminals and connection cables).

8.1.2 Operating logic

8.1.2.1 Operating modes

The equipment foresees the following operating modes:

x AUTOMATIC operating mode:

This mode mainly uses the renewable energy of the heat pump as a support measure, the electric heating elements can be enabled; these latter heating sources are enabled if the water temperature is below a certain level, or in the event that a temperature exceeding SP5 parameter is required;

x ECONOMY operating mode:

This mode uses only the renewable energy of the heat pump without ever enabling the electric heating elements. It takes longer to enable but it has considerable energy saving characteristics;

x OVERBOOST operating mode:

This mode makes it possible to heat water rapidly by using both the heat pump and the electric heating elements. This function can be manually enabled when the temperature of the water inside the storage tank is lower than SP3 parameter. At the end of the heating process, the function is automatically disabled and the equipment is automatically restored to the Automatic or Economy mode depending on which of these functions was previously set by the user;

x ANTI-LEGIONELLA operating mode

This function is used as an anti-bacterial treatment by increasing the temperature of the water to 60°C. This function is periodically and, in any case, automatically enabled every 30days, regardless of the operating mode enabled;

x DEFROSTING mode

This function is necessary in order to eliminate the frost deposits that form and which prevent heat transmission. This function is automatically enabled when the equipment is operated at low environmental temperatures.

8.1.3.13 Defrosting

Defrosting can be enabled in the following way:

x Automatically, when the temperature of the

evaporator is below that established in parameter d17 (only if P4 has a value other than 0);

In any case, between one defrosting procedure and another, the compressor must have been left switched on for a period either longer than or equal to d18 minutes. Otherwise the request to enable the defrosting procedure will not be accepted.

If P4 = 1, d2 represents the temperature of the evaporator, above which the defrosting procedure is terminated. Vice versa, if P4 = 0 or P4 = 2, parameter d2 is not taken into consideration.

If during the defrosting procedure the evaporate or probe is above the threshold set by means of parameters d2 and P4 = 1, the request to enable the defrosting procedure is not accepted.

The defrosting procedure consists of three stages:

x Defrosting stage: Parameter d3 establishes the

maximum duration of the stage. Output status:

x The compressor is active if d1 = 1,otherwise it is

switched off;

x The defrosting relay is active if d1 = 0 or d1 =

1,otherwise it is switched off;

x The fans are switched on if d1 = 2, otherwise they

are switched off.

x Dripping stage: Parameter d7 establishes the

duration of the stage. Output status:

- The compressor is switched off;

- The defrosting relay is active if d1 = 0 or d1 =

1,otherwise it is switched off;

- The fans are switched off.

x Drying stage.

Parameter d16 establishes the duration of the stage. Output status:

x The compressor acts according to parameter d8;

- The defrosting relay is active if d1 = 0 or d1 = 1,otherwise it is switched off;

- The fans are switched off.

8.2 Particular operations

The product has a fan speed control system that increases the speed of the same, when the ambient temperature drops to below -1°C, at higher temperatures, the fan maintains a lower speed in order to reducing the noise of the equipment.

The equipment is also provided with a verification system of the environmental conditions concerning the temperatures of the external incoming air. The below described function is necessary to avoid the equipment working with the heat pump mode out of specification, which may cause faults to the compressor and the consequent interruption of the functionality.

By every start, the fan is activated for a time set up by parameter C12 corresponding to 1 minute. After this time, the system measures the incoming air temperature. If the temperature is equal to or lower than parameter SP9 (-7°C), then the conditions for the activation of the heat pump unit are not met, therefore the electric resistance is activated. The heating-up process continues with the help of the electrical resistance until the set point established with the ongoing active cycle is reached.

The system verifies cyclically (every 120 minutes) the environmental conditions and activates the heat pump mode only when these conditions are adequate for its operation.
