3 UNIT COMPONENTS DESCRIPTION
REFRIGERANT CIRCUIT
Compressors
Crankcase heaters as standard, automatically activated when the unit stops, as long
as power is maintained to the unit.
System side heat exchanger
Brazed plate heat exchanger in stainless steel. It is externally insulated with closed
cell neoprene anti-condensation material.
Source side heat exchanger
Finned coil heat exchanger with copper tubes and aluminium louvers adequately
spaced to ensure high eciencies.
Desuperheater
Brazed plate heat exchanger in stainless steel. It is externally insulated with closed
cell neoprene anti-condensation material.
Reversing valve
4-way cycle inversion valve. Reverses the refrigerant uid ow.
Liquid accumulator
Compensates for the dierence in volume between the nned coil and the plate
heat exchanger, retaining the excessive liquid.
Filter drier
Hermetic-mechanical made of hygroscopic material, able to withhold impurities
and any traces of humidity present in the cooling circuit.
One-way valve
They allow one-way ow of the refrigerant.
Mechanic thermostatic valve
The mechanical type valve, with external equaliser located at the evaporator outlet,
modulates the ow of refrigerant into the evaporator based on the load and en-
sures the correct superheat of the suction gas.
Liquid sight glass with moisture indicator
Used to check for the presence of moisture in the refrigerant circuit.
HYDRAULIC CIRCUIT
Water lter
Equipped with steel ltering mesh, it prevents the heat-exchanger from clogging
system side due to any impurity inside the circuit.
Flow switch
Checks that water is circulating in the heat exchanger, and stops the unit if this is
not the case.
Pump
They provide useful static pressure to the system, excluding the unit pressure drops.
Expansion vessel
Membrane type precharged with nitrogen.
Pressure relief valve
Calibrated at 6 Bar and drain pipe, it activates by discharging overpressure if abnor-
mal pressure occurs.
Air drain valve
Mounted at the highest level of the hydraulic system. The air vent is used for the
release of any air pockets from the hydraulic circuit.
Of automatic type.
System buer tank
In steel to reduce heat gain and avoid the formation of condensation.
Insulated with polyurethane material of adequate thickness.
It reduces the number of compressor starts and stabilises the water temperature
delivered to the system.
Available only on request the tank in stainless steel AISI 304.
STRUCTURE AND FANS
Structure
Supporting structure for outdoor installation, in hot-dipped galvanized sheet steel,
with RAL 9003 polyester powder coating.
Designed to ensure the maximum access for service and maintenance.
The base for sizes 100 - 150 has holes in the proximity of the coil to permit drainage
of water during the defrost cycle.
Axial fans

7 SELECTION CRITERIA OF THE HEAT EXCHANGERS ACCORDING TO THE PLACE OF INSTALLATION OF
THE UNIT
The guide provides advice for applications. Although recommendations
are given, all the details about the real world application of our prod-
ucts cannot be fully covered in this document.
For these reasons, this section contains the basic warnings and precau-
tions to be taken into account in general, it being understood that:
— The nal choice of the type of exchanger according to the place of instal-
lation is left to the client (or to the professional appointed by him).
— In any case, it is recommended to wash the coils with adequate frequency
(a maximum time interval of three months is recommended, shorter in
conditions of particularly dirty and aggressive atmospheres) to preserve
their condition and ensure the proper functioning of the unit.
Potentially corrosive outdoor environments include areas near coasts, industrial
sites, densely populated urban areas, certain rural areas or a combination of these
environments. Other factors, including the presence of euent gas, sewage vents
or open sewage systems and the exhaust of diesel engines can all be harmful for
the microchannel coil.
The purpose of this application guide is to provide general information on the
mechanisms of corrosion and corrosive environments.
SEA COAST ENVIRONMENTS
Coastal or marine environments are characterized by the abundance of sodium
chloride (salt) which is carried by sea spray, mist, or fog. Most importantly, this salt
water can be carried more than several miles by ocean breezes and tidal currents.
It's not uncommon to experience salt-water contamination as far as 10km from the
coast.
For this reason, it may be necessary to protect the exchangers from electrolytes
of marine origin through the appropriate choice of materials and / or appropriate
protective treatment.
INDUSTRIAL ENVIRONMENTS
Industrial applications are associated with several dierent conditions that can po-
tentially produce a variety of atmospheric emissions.
Contaminants from sulphur and nitrogen oxides are most often linked to high-den-
sity urban environments. The combustion of coal oils and fuel oils releases sulphur
oxides (SO2, SO3) and nitrogen oxides (NOx) into the atmosphere. These gases ac-
cumulate in the atmosphere and return to the ground as acid rain or low pH dew.
Industrial emissions are not only potentially corrosive: many industrial dust parti-
cles can be loaded with harmful components such as metal oxides, chlorides, sul-
phates, sulfuric acid, carbon and carbon compounds.
In the presence of oxygen, water or high humidity environments, these particles
can be extremely corrosive and in several forms, including general and localised
corrosion, such as pitting and anthill.
MIX OF SEASIDE AND INDUSTRIAL ENVIRONMENTS
Sea mist loaded with salt, associated with the harmful emissions of an industrial
environment, poses a serious risk.
The combined eects of the salt loaded mist and in-dustrial emissions accelerate
corrosion.
Within the manufacturing plants, corrosive gas may result from the processing of
chemicals or by the typical industrial processes used in manufacturing.
Potential sources of risk to be considered are open sewage systems, exhaust vents,
diesel engine exhaust, emissions from heavy trac, landlls, aircraft and ocean-go-
ing ship engine exhaust, industrial production, chemical treatment facilities (cool-
ing towers in the vicinity) and fossil fuel power plants.
URBAN ENVIRONMENTS
Densely populated areas generally have high levels of emissions of motor vehicles
and increases in duel use for heating buildings.
Both conditions elevate sulfur oxide (SOx) and nitrogen oxide (NOx) concentrations.
Corrosive atmospheres may even occur in some closed areas, such as facilities with
swimming pools and water treatment systems.
It is advisable to pay particular attention to the positioning of the units if it occurs
in the immediate vicinity of these places, and to avoid that they are installed in the
vicinity of outlets for the expulsion of air coming from them, or in any case exposed
to such atmospheres.
Corrosion severity in this environment is a function of the pollution levels, which in
turn depend on several factors including population density in the area.
Any equipment installed in locations immediately adjacent to diesel engine ex-
hausts, incinerator ues, fuel-red boiler ues, or areas exposed to fossil fuel emis-
sions shall be considered subject to the same measures as an industrial application.
RURAL ENVIRONMENTS
Rural environments may contain high levels of pollution from ammonia and nitro-
gen products from animal excrements, fertilizers and high concentration of diesel
engine exhaust. The approach to these environments must be entirely similar to
that of industrial environments.
Local weather conditions have a major role in the concentration or disper-sion of
outdoor gaseous contaminants.
Thermal inversions can trap pollutants, thereby producing serious air pollution
problems.
ADDITIONAL TIPS
Although each of the above corrosive environments can be detrimental to the life
of the heat exchanger, several additional factors must be considered before choos-
ing the nal design.
The local climate surrounding the site of application may be inuenced by the pres-
ence of:
— wind
— dust
— road salts
— swimming pools
— diesel engines discharge / trac
— Localised mist
— cleaning agents for domestic use
— Sewage system outlets
— many other separate contaminants
Even within 3-5 km from these particular local climates a normal environment with
moderate characteristics can be classied as an environment that requires preven-
tive corrosion measures. When these factors are directly and immediately part of
the environment, their inuence is further aggravating.
Only in the absence of potentially risky situations such as those indicated above can
an environment be considered moderate.
Application Tip
Severe environments Coils with suitable protection
Moderate environments Standard coil °

12 SYSTEM WATER CONTENT
MINIMUM SYSTEM WATER CONTENT
For correct unit operation, there must be a suitable amount of water in the system. A sucient quantity of water not only ensures machine stability, but also helps avoid a high
number of hourly compressor start-ups.
To calculate it, use the formula: Unit rated cooling capacity (ton) x table value (gal/ton) = Minimum system content (gal).
Size 100 150
Minimum system water content
Minimum water content for air conditioning °,A,P gal/ton 3.7 3.7
Note: the water content referred to in the tables corresponds to the amount of water eectively useful for inertial purposes; this value does not necessarily coincide with the
entire system water content, and must be calculated on the basis of the system layout and operating modes.
A example is given below, but it does not cover a possible situation.
Example: for a chiller/heat pump equipped with a primary and a secondary circuit, and in which the zone pumps of the secondary circuit could (even occasionally) be turned
o, only the water content of the primary circuit has value of useful water content for the counting purposes.
If you are in any doubt, please refer to the relevant technical documentation or contact the AERMEC Technical-Commercial Service.
NOTICE: Under no circumstances does the unit have to be operated when water ow rate on the heat exchanger is below the minimum water ow rate or above the
maximum water ow rate, under penalty of the warranty expiration. Aermec cannot be held responsible for any malfunction of the units which are operated outside
the established limits of water ow rate and for their consequences
NOTICE: Under no circumstances does the unit have to be operated in a system in which the content of the water circulating is below the MINIMUM SYSTEM WATER
CONTENT, under penalty of the warranty expiration. Aermec cannot be held responsible for any malfunction of the units which are operated in a system in which the
content of the water circulating is below the MINIMUM SYSTEM WATER CONTENT and for their consequences
NOTICE: in the case of several units connected in parallel, the designer must ensure that the conguration of the system and the management logic adopted do not
cause too frequent START/STOP cycles and / or sudden changes in the water ow rate of the groups in operation
ATTENTION It is recommended to design systems with high water content (minimum recommended values shown in tab), in order to limit:
— Number of peaks made by the compressors
— The reduction of water temperature during defrosting cycles in the winter period for heat pumps.
NOTICE: in the case of several units connected in parallel, the designer must ensure that the conguration of the system and the management logic adopted do not
cause too frequent START/STOP cycles and / or sudden changes in the water ow rate of the groups in operation
MAXIMUM SYSTEM WATER CONTENT
Units with the hydronic kit mounted come standard with the expansion vessel set at 21.8 psi, the pressure relief valve and the water lter mounted.
The maximum system water content depends on the capacity of the expansion vessel and on the calibration of the pressure relief valve.

EXPANSION VESSEL SETTING
The expansion tank volume is 6.3 gal. The standard value of the expansion tank pre-charge pressure is 21.8 psi, but this can be calibrated up to a maximum of 87.0 psi.
The expansion tank pressure setting has to be adjusted based on the dierence in height (H) of the installation (see gure) according to the formula: p (rating) [psi] = H [ft] /
10,2 + 0,3.
For example: if level dierence H is equal to 65.6 ft, the calibration value of the vessel will be 33.4 psi.
If the calculated pressure setting value is less than 21.8 psi (when H < 12.25), maintain the standard pressure setting.
