SRPUY 5890911_00 10/04

The SRP heat pump can provide winter climatisation and the the production of DHW.

The AERMEC units are only powered with electricity, there is no combustion, open flame, gas in the air, in living environments. Moreover, there is no need for flues for combustion product exhaust and reduced maintenance is required with respect to traditional heating plants, for the use of sealed refrigerant circuits and lower working temperatures.

Thanks to the high efficiency Scroll compressor, the heat pumps produce hot water (SYSTEM) up to 65°C, therefore suitable for heating rooms also through normal radiators and for functioning with external temperatures that can go from -20 °C to 35 °C.

Particular attention has been paid to acoustic material and particularly the choice of PLUG-FANS with high static pressure and silence, in order to obtain silent functioning conditions.

The Aermec heat pumps are ready for immediate installation. Just connect the machine to the water and electric system in order to start it. The small dimensions and the particular construction allow installation inside and outside of the home.

With the help of the configurator it is possible to set-up and therefore order the heat pump that best satisfies the requests of the user.

4. DESCRIPTION

COMPONENTS

OF

Liquid storage

It is used to keep the refrigerant gas, which is present in the cooling circuit, in the liquid state.

Compressor

High efficient hermetic scroll on antivibration mounts, activated by a

2-pole electric motor with internal heat protection.

The compressor is also supplied, as standard, with an electric oil sump resistance, powered automatically when the unit stops as long as the unit is live.

Condenser + Anti-freeze resistance

Braze welded plate heat exchanger

(AISI 316) insulated externally with closed cell material to reduce heat loss, it is large to allow high efficiency.

Evaporator

Made with copper pipes and aluminium louvered fins blocked by mechanical expansion of the pipes.

Dehydrator filter

Mechanical dehydrator filter realised in ceramics and hygroscopic material, able to withhold impurities and any traces of humidity present in the cooling circuit.

Thermostatic valves

The mechanical valves, with external equaliser positioned at condenser outlet, modulates the flow of gas to the condenser, depending on the heat load, in order to ensure a correct heating level of the intake gas.

Economizer

Plate type (AISI 316). This allows to further undercool the refrigerant liquid exiting the condenser and makes a certain steam capacity available to be injected in an intermediate point of the compression process, thus reducing the flow temperature and electrical absorption.

Solenoid valves

A solenoid valve excludes the economizer

The second valve enables injection of the liquid.

Cycle reversing valve

Inverts the flow of refrigerant by activating the defrosting cycle.

One way valves

Allows one-way flow of the refrigerant.

Liquid indicator

Used to check the refrigerant gas load and any presence of humidity in the cooling circuit.

Water filter

This allows to block any impurities present in the hydraulic circuit. It contains a filtering mesh with holes that do not exceed one millimetre.

It is useful to guarantee correct functioning.

Safety valve

Calibrated at 3 Bar and with piped discharger that discharges if abnormal pressure occurs.

Air vent valve

Manual type sees to discharge of eventual air pockets.

Drain cock

Allows to drain the water present in the heat exchanger.

Electric resistances

Can be configured depending on requirements, they supply additional energy if heat pump performance cannot satisfy the effective requirements due to unfavourable environmental conditions.

They can be integrative or replaceable.

4.3. FRAME AND FAN

Support frame

Made in hot galvanised sheet steel with suitable thickness and painted with polyester powders able to resist atmospheric agents through time.

PLUG-FAN

Reverse blades, with motor with external rotor. Thanks to its special construction, the fan is very small and characterised by particularly silent functioning.

4.4. CONTROL AND SAFETY

COMPONENTS

Low pressure transducers

Placed on high pressure side of cooling circuit, signals the work pressure to control board, generating a prewarning in case abnormal pressure occurs.

High pressure transducer

Placed on high pressure side of cooling circuit, signals the work pressure to control board, generating a prewarning in case abnormal pressure occurs.

High pressure pressure switch

With fixed calibration, positioned on the high pressure side of the cooling circuit, it stops compressor functioning in the case of anomalous work pressures.

4.5. ELECTRONIC MODU CONTROL

ADJUSTMENT

MODU_CONTROL

Temperature control of the output water with proportional-integral algorithm: maintains average output temperature at value set

− Self-adapting differential switch: guarantees minimum functioning times of the compressor in systems with low water content.

− Intelligent defrosting for pressure reduction: allows to determine when the coil is effectively defrosted, avoiding useless defrosting

− Hot gas injection defrosting: in this way the machine consumes less energy, increases heating capacity, keeps effi ciency high and prevents temperature drops at the terminals

(very important in plants with low water content).

− Emergency defrosting by cooling cycle reversing: to overcome more serious conditions

− Set-point compensation with external temperature (with external air probe accessory): reduces energy consumption

− Condensation control based on the pressure instead of the temperature, for absolute stability)

− Inverse condensation control for heat pump functioning also in the summer

− Pre-alarms with automatic reset in the case of alarm, a certain number of re-starts are allowed before the defi nitive block.

− alarm on the ∆T: to identify wiring errors (reverse rotation) or blocked cycle reversing valve.

− Compressor functioning hours count.

− Compressor peak count.

− Historical

− Autostart after voltage drop.

− Local or remote control

− The pressure drop correction factor considers the different fl ow rate resulting from the application of the water fl ow rate correction factor.

is calculated to keep the same ∆t that would be present with the absence of glycol.

NOTE

On the following page an example is given to help graph reading.

To determine the percentage of glycol required, see below diagram; this percentage calculation can take into consideration one of the following factors:

Depending on which fluid is considered

(water or air), the graph is interpreted by the right or left side at the crossing point on the curves with the external temperature line or the water produced line. A point from which the vertical line will pass is obtained and this will distinguish both glycol percentage and relative correction coefficients.

10.1. HOW TO INTERPRET GLYCOL

CURVES

The curves shown in the diagram summarise a significant number of data, each of which is represented by a specific curve. In order to use these curves correctly it is first necessary to make some initial reflections.

− If you wish to calculate the percentage of glycol on the basis of the external air temperature, enter from the left axis and on reaching the curve draw a vertical line, which in turn will intercept all the other curves; the points obtained from the upper curves represent the coeffi cients for the correction of the cooling capacity and input power, the fl ow rates and the pressure drops (remember that these coeffi cients must be multiplied by the nominal value of the size in question); while the glycol percentage value recommended to produce desired water temperature is on the lower axis.

− If you wish to calculate the percentage of glycol on the basis of the temperature of the water produced, enter from the right axis and on reaching the curve draw a vertical line, which in turn will intercept all the other curves; the

If the unit power supply is restored after a temporary interruption, the set mode will be kept in the memory.

20.2. COMPRESSOR START-UP DELAY

Two functions have been prepared to prevent compressor start-ups that are too close.

− Minimum time from last switch-off 180 seconds.

− Minimum time from last switch-on 300 seconds.

The circuit board envisions an output for pump management, which starts on commissioning and remains on for at least

150 seconds and controls the state of the probes.

After the fi rst 40 seconds that the pump functions, when the water fl ow rate is in normal working conditions, the water fl ow rate alarm functions are activated

(differential pressure switch).

When the machine enters stand-by, the pump remains on for 30 secs and controls the unit pressure switch at the different external temperatures, the MODUCONTROL by reading the pressure via the pressure probe, controls the rotation speed of the fans, thus allowing to increase and/or decrease heat exchange, keeping the condensation or evaporation pressures more or less constant. The fan functions independently with respect to the compressor.

The anti-freeze alarm is never active if the machine is off or in stand-by mode. In order to prevent breakage of the plate heat exchanger due to freezing of the water it contains, the MODUCONTROL blocks the compressor and ignition of the resistance

(ACCESSORY) if the temperature detected by the probe positioned at the outlet of the heat exchanger and in inlet to the chiller is below +4°C.

THIS ANTI-FREEZE SET TEMPERATURE CAN

ONLY BE VARIED BY AN AUTHORISED AFTER-

SALES CENTRE AND ONLY AFTER HAVING

CHECKED THAT THERE IS ANTI-FREEZE

SOLUTION IN THE WATER SYSTEM.

The intervention of this alarm determines compressor block and not pump block, which remains active along with the switchon of the resistance if installed.

To restore normal functions the temperature of the outlet water must rise above +4°C.

Rearm is manual.

WHENEVER THIS ALARM INTERVENES, WE

ADVISE YOU CALL THE NEAREST AFTER-SALES

SERVICE IMMEDIATELY.

20.5. WATER FLOW RATE ALARM

The MODUCONTROL manages a water fl ow rate alarm controlled by the differential pressure switch installed in series on the machine.

This type of safety device intervenes after the fi rst 40 seconds of pump functioning, if the water fl ow rate is not suffi cient.

The intervention of this alarm determines compressor and pump block.

WARNING

Inspection, maintenance and eventual repair work must be carried out only by a legally qualified technician.

Lack of control/maintenance can cause damage to persons or things.

For appliances installed near to the sea, the maintenance intervals must be halved.

21. MAINTENANCE

All cleaning is prohibited until the unit has been disconnected from the electric power supply mains.

Make sure there is no voltage present before operating.

Periodic maintenance is fundamental to keep the unit perfectly effi cient under a functional and energetic point of view.

It is therefore essential to carry out periodic yearly controls for the:

21.5.1. Hydraulic circuit

− Refi lling of water circuit

− Clean the water fi lter. fl ow switch/pressure switch

− Bleed the air from the circuit.

− Verify that the water fl ow rate to the evaporator is constant.

− Verify the thermal insulation of the hydraulic piping.

− Check the percentage of glycol where necessary

21.5.2. Electric circuit checks

effi ciency

− Electric supply pressure

Input

− Connection

− Verify the operation of the carter compressor resistance

21.5.3. Cooling circuit checks

− State of compressor

− Effi ciency of the plate heat exchanger resistance if envisioned

− Work

− Leak test for watertightness control of the cooling circuit

− Functioning of high and low pressure pressure switches

− Carry out the appropriate checks on the fi lter dryer to check effi ciency

21.5.4. Mechanical checks

− Check the tightening of the screws the compressors and the electrical box, as well as the exterior panelling of the unit. Insuffi cient fastening can lead to undesired noise and

26

SRPUY 5890911_00 10/04

− vibrations

− Check the condition of the structure.

If there are any oxidised parts, treat with paint suitable to eliminate or reduce oxidation.

21.1. EXTRAORDINARY

MAINTENANCE

The SRPs are filled with R407C gas and are inspected at the factory. Under normal conditions they do not require

Technical Assistance related to control of refrigerant gas. Through time gas leakage may be generated from the from the joints, causing refrigerant to escape and discharge the circuit, causing appliance malfunctioning. In these cases the leakage points are to be discovered, repaired and the Gas circuit is to be replenished, respecting the December 28 1993 n°549 law.

21.1.1. Load procedure

The load procedure is the following:

− Empty and dry the entire cooling circuit using a vacuum pump connected to the low and high pressure socket until 10 Pa is read on the vacuum meter. Wait a few minutes and check that this value does not rise above 50 Pa.

− Connect the refrigerant gas cylinder or a load cylinder to the socket on the low pressure line.

− Load the amount of refrigerant gas indicated on the appliance features plate.

− The R407C refrigerant must only be loaded in the liquid state.

− Functioning conditions that are different to the nominal conditions can give rise to values that are greatly different.

− The sealing test or the search for leaks must only be performed using

R407C refrigerant gas, checking using a suitable leak detector.

− In the cooling circuit it is prohibited to use oxygen or acetylene or other infl ammable or poisonous gases because they are a cause of explosions or intoxication.

We recommend to envision a machine book (not supplied, but the user's responsibility), which allows to keep track of the interventions performed on the unit. In this way it will be easy to suitably organise the interventions making research and the prevention of any machine breakdowns easier.

Use the date to record date, type of intervention made

(routine maintenance, inspection or repairs), description of the intervention, measures actuated…

IT IS forbidden to RELOAD the circuit with a refrigerant gas different to the one indicated.

Using a different refrigerant gas can cause serious damage to the compressor.

DISPOSAL

Envisions that disposal of the unit is carried out in conformity with the Standards in force in the different countries

22. LIST OF CONTROLS FOR

THE GUIDED PROCEDURE

Some parameters in the moducontrol board must be set appropriately on the basis of the type of system in which the unit is installed.

These modifi cations, performed by the installer, are summarised and organised in the following guided procedures, with which to correctly set the unit circuit board parameters.

How to modify a parameter in the user menu:

To enter the USER menu, press the key shown in (Fig.A).

Once the key has been pressed the password must be inserted for access to the various menus. To access the user menu the password is 000 (which is the default displayed); to modify the value of the password use the arrow keys.

Once the correct password has been inserted, press the key shown in (Fig.A). The display shows the index of the USER parameter and a string of three characters that identify it.

The string remains displayed for one second, after which it is replaced by the value relative to the parameter itself.

To pass to the next parameter, use the arrow keys (Fig.B).

To modify a parameter, just select it, press the key shown in (Fig.A), modify the value using the arrow keys shown in

(Fig.B). To confi rm the modifi cation press the key shown in

(Fig.A) again.
