ALEZIO O HYBRID

ALEZIO O Hybrid is a range of air/water Inverter heat pumps, comprising an outdoor unit and a hydraulic indoor module incorporating:- A floor-standing EFU type 22.4 or 29.8 kW oil boiler and a 180 litre

hybrid DHW tank. - A floor-standing EFU C type 19.3, 24.3 or 32 kW condensing

oil boiler and a 180 litre hybrid DHW tank. - Operates down to -20°C (-15°C for the 4 and 6 kW versions),- Single or three phase power supply,- Start-up current limitation using INVERTER technology.

The heat pumps in this range stand out because of their performances: COP of 4.05 to 4.65 at an outside air temperature of +7°C/+35°C (EER of 3.99 to 4.75 at a temperature of +35°C/+18°C). High-tech products fitted with the INVERTER output storage system, they improve set point temperature stability, significantly reduce electricity consumption and run silently. Thanks to their reversibility and the underfloor cooling type cooling option (water at +18°C), by fan coil units when they are fitted with the “Insulation Kit” (water at +7°C), they provide absolute year round comfort.

As for the hybrid function, it enables the simultaneous or separate management of the heat pump and the oil boiler according to weather conditions and heating needs: one of the aims of the hybrid function is to meet those needs by always consuming the most efficient energy, whether gas or electricity, i.e.:- Either the cheapest energy (to optimise heating costs),- Or the one that uses the least primary energy or generates the lowest CO2

emissions as part of an environmentally friendly approach.

COMPLEMENTARY CONTROL SYSTEM FUNCTIONS

THE “HYBRID” FUNCTION

The hybrid function in the inside module control system is used to manage solutions that combine an HP (using a proportion of renewable energy) and a condensing boiler (oil or gas) running alone or simultaneously, depending on weather conditions and heating needs.

The aim of the hybrid function is to meet the system's needs by always consuming the most efficient energy, be it gas, oil or electricity, i.e.:- Either the cheapest energy (to optimise heating costs),- Or the one that uses the least primary energy as part of an

environmentally friendly approach.The values corresponding to the "energy price" or the "primary energy factor" can be modified in the control system parameters.

The advantages of this method of management are also:- Reduction in HP output for a low-cost electricity contract (no

surcharge for an electrical back-up system)- 100% cover of heating and DHW needs by the HP + boiler

system- In an existing home, energy savings compared with running a

boiler only, reduction in CO2 emissions from the boiler already in place, connection possible without having to replace any existing heat-emitting devices or having to resort to very high temperature devices.

To heat and light our homes and produce domestic hot water, we consume energy (oil, wood, gas, electricity). The final energy used by the consumer is not always available in the natural state (e.g. electricity) and sometimes requires processing. The primary energy represents the energy used to carry out such processing. The primary energy is quantified by "the primary energy factor",

which expresses the amount of primary energy required to obtain one unit of energy. For electricity, the factor is 2.5, which means that it is necessary to consume 2.5 kWh of primary energy to obtain 1 kWh of electrical energy. For natural gas and oil, this factor is 1 (gas and oil are primary energies).

Primary energy

Performances of a hybrid solutionThe graph below presents a performance comparison (COP) for heating and DHW production in the primary energy used for various solutions:- The hybrid solution: combination of an HP and a condensing

boiler (renewable energy, electrical energy and gas or oil energy),

- The solution with an HP only (renewable energy with electrical back-up),

- The solution with a condensing boiler only (oil or gas energy).

For an outside air temperature lower than the switch-over point, the hybrid solution improves system performances (COP on primary energy) compared with an HP used on its own. Likewise for an air temperature higher than the switch-over point, the hybrid solution shows better performances that those of a condensing boiler used on its own.

COMPLEMENTARY CONTROL SYSTEM FUNCTIONS

EXAMPLES OF HYBRID SOLUTIONSExample of a hybrid solution according to the primary energy factor

Example of a hybrid solution according to energy cost

The graph opposite illustrates the various hybrid solutions according to outside air temperature and energy cost.When the COP of the HP > 2.5 and the Tair > Teq alone, the HP will be called upon. For Toff < Tair < Teq, the control system runs the HP in combination with the boiler. When the COP of the HP < 2.5 the control system runs the boiler only.For each configuration, it is therefore the control system that decides which generator or combination of generators will be used to meet heating and DHW needs.The principle of management according to primary energy is especially valid in new homes.

The graph below illustrates the operating principle of the hybrid solution according to outside air temperature and energy cost.Calculating the energy price ratio R:

R = electricity price (€/kWh)

= 0.15/0.07 = 2.1 Gas price (€/kWh)(the energy price factors in the annual contract) It is factor R (calculated energy price ratio) and the outside air temperature which are used as parameters by the control system to define the various operating modes. In the example opposite:- The HP is an AWHP 8 MR-EFU…HYBRID model- The generators are installed in an existing house of 130 m2.When the COP of the HP > 2.1 and T air > +2°C, the control system runs the HP only to meet heating needs and DHW production.When the COP of the HP > 2.1 and -5°C < T air < +2°C, the control system runs the HP in combination with the boiler. When the COP of the HP < 2.1, the control system runs the boiler only.For each configuration, it is therefore the control system that decides which generator or combination of generators will be used to meet heating and DHW needs.

Comment:Operation of the hybrid function is activated:- If the outside temperature is higher than the HP shut-down temperature (-20°C,

-15°C for 4 and 6 MR), the HP is always started up first and the boiler back-up is called upon only if heating needs are higher than the HP can provide.

- If the outside temperature is lower than the HP shut-down temperature, the boiler will handle heating needs on its own.

SIZING AN ALEZIO O Hybrid SYSTEM

SIZING RULESThe sizing of the HP and the boiler is done in relation to the heat losses calculation. The heat losses are calculated according to the NF EN 12831 standard. The losses are calculated for the rooms heated by the HP and are broken down into: - Surface losses through walls and partitions,- Unit length losses via links between the different surfaces,- Losses by air renewal and infiltration.

For optimum sizing, the following rules should be observed:- 50% of losses � HP output � 60% of losses - Boiler output = 120% of losses

INFORMATION REQUIRED FOR INSTALLATION

POSITIONING THE OUTDOOR UNIT

- The outdoor units for ALEZIO O Hybrid heat pumps should be installed close to the house, on a terrace, on the façade or in a garden. They are designed to operate in the rain but can also be installed under cover as long as there is sufficient ventilation.

- The outdoor unit must be installed protected from prevailing winds that may influence the installation’s performance.

- We recommend positioning the unit above the average depth of snowfall in the region in which it is installed.

- The emplacement of the outdoor unit should be carefully chosen in order for it to be compatible with environmental requirements: integration in the site, compliance with planning rules or co-ownership agreements.

- No obstacles must hinder the free circulation of air around the exchanger on intake and output. It is therefore necessary to allow clearance all around the appliance that will also facilitate connection, commissioning and maintenance operations (see installation diagrams below).

Acoustic integration

The acoustic performances of the outside units are defined by the following two values:- The acoustic power Lw expressed in dB(A): this

characterises the sound emission capacity of the source independent of its environment. It is used to compare appliances with each other.

- The acoustic pressure Lp expressed in dB(A): this is the value perceived by the human ear. It depends on parameters such as the distance from the source, and the size and nature of the walls of the premises. The regulations are based on this value.

Definitions

The regulation on neighbourhood noise can be found in the Decree of 31/08/2006 and in the NF S 31-010 standard. Noise is defined by emergence, which is the difference between the level of acoustic pressure measured when the appliance is off compared with the level measured when the appliance is running in the same place.

The maximum difference permitted is:- Day time (7 a.m. - 10 p.m.): 5 dB(A)- Night time (10 p.m. - 7 a.m.): 3 dB(A)

Noise

- Do not place it in the vicinity of sleeping areas,- Avoid proximity with a terrace, do not install the module

opposite a wall. The increase in noise level caused by the installation configuration is shown in the diagrams below:

- The various set-ups below should be avoided:

- In order to limit noise and the transmission of vibrations, we recommend:• Installing the outdoor module on a metal frame or an inertia

base frame. The mass of such a base frame must be at least

twice the mass of the module and it must be independent of the building. In all cases, anti-vibration studs must be fitted to reduce the transmission of vibrations.

• To pass refrigerant connections through walls, use appropriate sleeves,

• For the fittings, use flexible, vibration-proof materials,• Install vibration reduction devices on refrigerant connections,

such a loops, brackets and elbows.- We also recommend installing a noise reduction device in the

form of:• A wall damper to be fitted to the wall behind the module,• An acoustic screen: the surface area of the screen must

greater than the dimensions of the outdoor module and it must be positioned as close to it as possible while allowing air to circulate freely. The screen must be made of an appropriate material such as acoustic bricks, concrete blocks coated with absorbent materials. It is also possible to use natural screens such as embankments of earth.

Recommendations on the acoustic integration of the outdoor module

HYDRAULIC CONNECTIONThe indoor modules of ALEZIO O Hybrid heat pumps are fully fitted out for the connection of a direct circuit (radiators or underfloor heating): circulating pump with energy efficiency index EEI < 0.23, expansion vessel, heating safety valve, pressure gauge, air vent…The connection of a second circuit (underfloor heating) is possible by incorporating an optional “3-way valve kit - Package EH528“.

Comment: As ALEZIO O Hybrid heat pumps are “SPLIT INVERTER” models with a refrigerant link between the outdoor unit and the indoor module, it is not necessary to add glycol to the installation.

Important comments on:The various emitters

The heat pumps’ water outlet temperature is limited: max. 65°C. It is therefore imperative to work on low temperature emitters, i.e. underfloor heating/cooling or radiators sized for low temperature. For cooling mode, underfloor heating with compatible slab and covering only is suitable. It is also necessary to observe minimum underfloor cooling flow temperatures in line with the geographical area of installation to prevent any condensation (between 18°C and 22°C).

Refrigerant fluids The refrigerant fluid, R 410 A, has properties suitable for heat pumps. It belongs to the HFC family (hydrofluorocarbons), composed of chemical molecules containing carbon, fluorine and hydrogen. They do not contain chlorine and are therefore not damaging to the ozone layer.

Cooling or air conditioning modeSo-called reversible heat pumps can be use for cooling in the summer. A 4-way valve, called a cycle reversal valve, switches the cycle from heating mode to cooling mode.The compressor intake is connected to the internal exchanger and thus becomes an evaporator. The compressor backflow is connected to the external exchanger and thus becomes a condenser.Note: For Air/Water type HPs, this 4-way valve is also used for the evaporator defrosting phase.In the case of an installation with underfloor heating/cooling (flow/return water temp.: +18°C/+23°C), the refrigerant output is limited, but sufficient, to keep conditions pleasantly comfortable inside the home. This allows an average reduction in room temperature of 3 to 4°C. In the case of an installation with fan coil units (flow/return water temp.: +7°C/+12°C), it is necessary to order the optional “insulation kit for air conditioning mode - Package EH567”.

SIZING THE BUFFER TANKThe volume of water in the heating installation must be able to store all of the energy provided by the HP during its minimum operating time. The storage volume therefore corresponds to the minimum volume of water required, the capacity of which is drawn from the mains. - Installation of a storage tank is advisable for installations with a

water volume of fewer than 5 l/kW HP heating power (factor in the volume of water in the indoor module).

- Increasing the volume in an installation limits short cycle running of the compressor (the greater the water volume, the fewer the number of compressor start-ups and the longer its lifespan).

- As an initial approach, below is an estimated storage volume for a minimum operating time of 6 minutes, a regulation differential of 5 K and factoring in a negligible mains volume (factor in the water volume in the indoor module).

EXAMPLES OF INSTALLATIONS

The examples presented below cannot cover the full range of installation scenarios that may be encountered. Their purpose is to draw the attention to the basic rules to be followed. A certain number of control and safety devices are shown but it is ultimately up to experts, consultant engineers and design departments to take the final decision on the safety and control devices to be used in the boiler room according to its specificities. In all cases, it is necessary to abide by the codes of practice and prevailing regulations.

Attention: for the connection of domestic hot water, a sleeve made of steel, cast iron or any other insulating material must be interposed between the hot water outlet and these pipes to prevent any corrosion to the connections, if the distribution pipes are made of copper.
