Carrier AQUASNAP 30RA010-055 Operation manual

Copyright 2009 Carrier Corporation Form 30RA-5PD
The AquaSnap chiller is an effective all-
in-one package that is easy to install
and easy to own. AquaSnap chillers
cost less to purchase and install, and
operate quietly and efficiently. Value-
added features include:
• Scroll compression
• Low profile construction
• Quiet AeroAcoustic™ fan system
• Easy to use ComfortLink™ controls
• Integrated hydronic pump package
• Accessory fluid storage tank
Features/Benefits
Carrier’s superior chiller
design provides savings at
initial purchase, at installa-
tion, and for years afterward.
Costs less right from the start
Only Carrier’s AquaSnap chillers fea-
ture a compact, all-in-one package de-
sign that installs quickly and easily on
the ground or the rooftop. The option-
al pump and hydronic components are
already built in; this costs less than buy-
ing and installing the components indi-
vidually. The chiller’s fully integrated
and pre-assembled hydronic system in-
stalls in minutes. No other chiller in
this class installs so easily and inexpen-
sively. The preassembled and integrat-
ed hydronic module utilizes top-quality
components and pumps to ensure
years of reliable operation. Use of the
optional fluid storage tank reduces in-
stallation costs and ensures sufficient
fluid volume is available for close-cou-
pled and process cooling applications.
The AquaSnap unit’s high efficiency
keeps costs down.

AquaSnap®chillers make
noise in the marketplace, not
the workplace.
The AquaSnap chiller’s AeroAcous-
tic™ fan is almost twice as quiet as the
competition’s per cfm, which makes
AquaSnap chillers ideal for sound-
sensitive environments. When lower
ambient temperatures allow part-load
operation or during scheduled night-
time operation, the units operate with
fewer fans and become even quieter.
AquaSnap chillers are quiet during the
day and even quieter at night.
The fan is mounted to an extremely
rigid tower, which further reduces
vibrations and noise by preventing
them from being amplified through the
unit’s casing.
The savings will continue to
mount
Besides costing less to buy and install,
AquaSnap chillers are also more af-
fordable to operate. They are very effi-
cient air-cooled models, with full-load
EER (Energy Efficiency Ratio) up to
10.1. AquaSnap chillers use ultraquiet,
high-efficiency scroll compressors, op-
erated in tandem for greater efficiency
at partial loads.
Proven reliability that’s built in
Thousands of AquaSnap chillers are
already in service around the world.
This field-proven design is backed by a
12-month warranty that includes the
hydronic system. The compressors are
maintenance-free and protected by an
auto-adaptive control that minimizes
compressor wear. Unit sizes 035 and
up have two independent refrigerant
circuits. Year-round operation is
standard, from –20 F (–29 C) (with
optional cooler heater and low ambient
control) to 125 F (52 C).
ComfortLinkTM controls speak
your language
The ComfortLink controls communi-
cate in plain English, making it as easy
as possible to monitor and control
each AquaSnap chiller while accurately
maintaining fluid temperatures. The
large scrolling marquee display acts as
a window into the unit’s operation,
providing easy-to-read information
about chiller performance and over
15 diagnostic functions. Carrier 30
Series chillers’ ComfortLink controls
provide features such as chilled water
temperature reset, demand limiting,
compressor wear minimization and
protection, temperature and pressure
displays and diagnostic functions.
These controls result in higher chiller
reliability, simplified training and more
productive service calls with corre-
spondingly lower operational and
maintenance costs.
Carrier’s exclusive handheld
Navigator™ display provides conve-
nience and powerful information in the
palm of your hand. The Navigator
display helps technicians to quickly
diagnose problems and even prevent
them from occurring.
All AquaSnap units are ready to
be used with the Carrier Comfort
Network®(CCN) system.
AquaSnap units minimize the
impact on your roofline, as
well as your bottom line
The AquaSnap chiller’s low profile —
all models are just 4'-4" (1321 mm)
high — means it will not stand out if in-
stalled on the roof. The other dimen-
sions are equally compact. The inte-
grated hydronics and the chilled fluid
storage tank’s placement under the
chiller further minimize the footprint,
allowing easy installation almost any-
where.

Selection procedure

AquaSnap®pump selection
Several pump sizes are available for each AquaSnap chiller
size to provide flexibility in matching water system require-
ments. A dual pump option is also available for primary/
standby operation. The Carrier E-Cat Packaged AC Chiller
Builder can be used for pump selection, or selection can be
done manually.
Proper water system design is critical; cooling loads,
water pressure drops and proper water line sizing must be
accounted for in order to ensure proper system operation.
Incorrect or incomplete analysis/design of the water loop
could lead to low water flow, loss of water temperature
control, and excessive cycling of chiller compressors.
The following are the steps for manual selection of water
pumps for the 30RA chillers.
1. Calculate the water flow rate (gpm) and the total
water pressure drop of the system external to the
30RA chiller.
2. Determine the internal pressure drop of the chiller
hydronic package based on the design flow rate (refer
to internal Pressure Drop tables on page 22). Values
given in these charts are based on units with clean
strainers and circuit setter valve wide open.
NOTE: These pressure drops are for water. If glycol is
used, correct by multiplying by the factors below.
3. If an optional storage tank is used, determine the
internal pressure drop by referencing the internal
Pressure Drop tables on page 24.
NOTE: Note that these pressure drops are for water. If gly-
col is used, correct by multiplying by the factors below.
4. Add pressure drops found in Steps 1-3. This is the
total pressure drop and total head required by the
pump.
5. Use the pump envelope charts (page 25) to deter-
mine proper pump sizing. Plot water flow rate
(Step 1) and total head (Step 4), point on the chart.
The region containing the point corresponds to the
correct pump.
NOTE: Although pump bhp increases with glycol concen-
tration, pumps and pump overloads are selected such that
glycol concentrations up to 50% will not trip pump over-
loads if run within the recommended gpm ranges.
Example: Required water flow rate for a 30RA018
chiller is 45 gpm. The pressure drop in feet for the water
system external to the chiller is 50 feet. The system does
not have an accessory storage tank. The single pump is
needed. Select the pump.
Since the flow rate and external head losses (Step 1) are
known, the internal losses in the hydronic package must be
found (Step 2). Using the pressure drop graphs (page 22)
for the 30RA018 units, the internal loss at 45 gpm is
15 feet. Since no accessory storage tank is being used
(Step 3), the pressure drop is 0 feet.
Add all losses together (Step 4). The total pressure rise
