BROAD PACKAGED POWER-EFFICIENT CHILLER
MODEL SELECTION & DESIGN MANUAL
BROAD CENTRAL AIR CONDITIONING
2016 08 SI
Application· Provide chilled / heating water for
central air conditioning system· Produce chilled water over 3℃ and
heating water below 60℃
Cooling capacity 420~4,650kW (120~1,329RT)
VALUES OF BROAD POWER-EFFICIENT CHILLER
ENERGY SAVINGThe Integrated Part Load Value (IPLV) of the chiller can reach 11. This high IPLV can reduce energy consumption by 40% when compared to traditional electric chillersA BROAD Packaged Water Distribution System can reduces electricity consumption up to 76% when
compared to conventional field-built systems
ADDITIONAL COST SAVINGSThe magnetic oil free and zero friction technology can save up to 40% energy cost and 90% of maintenance cost when compared with traditional electric chillers. BROAD PLC “Smart anti-surge control” module insures the chiller always operate in a safe range. The integrated design of the BROAD chiller, water distribution system and stainless steel metal
enclosure reduce design cost and field installation costs for customers
SPACE SAVING Compared with the traditional electric chillers, A BROAD chiller package reduces volume by 30~50% and the weight by 30%BROAD Packaged Water Distribution System and stainless steel metal enclosures can be installed outside
which reduces mechanical room footprint requirements
WORRY-FREEBROAD Packaged Water Distribution System and stainless steel metal enclosure eliminate risk and reduce system design, procurement and installation errorsBROAD Intelligent Control System (ICS) can be automated for operator free operation of the chiller and water distribution system. BROAD Global Internet Monitoring System provides customers with 24/7/365 fault prediction, analysis and energy-saving management tools
AS THE GLOBAL LEADER OF NON-ELECTRIC CHILLER, WHY BROAD ALSO MAKES ELECTRIC CHILLER?
The BROAD non-electric chiller is the world’s most efficient method to produce chilled water when evaluating original source “primary energy fuels”. A BROAD Direct Fired Absorption Chiller/Heater is able to generate chilled, heating and domestic hot water simultaneously. These three outputs from a single absorption unit is the most reliable system when looking at potential points of failure. The BROAD Generation XI Absorption Chiller provides the longest life span and the quietest operation available in the market today.With the emergence of growing CHP, wind and solar PV power systems we are now manufacturing the power-efficient chiller.Markets for the new power-efficient chiller are as follows:1. Locations of the developing world where there is no access to natural gas or waste energy sources2. Applications for small cooling only requirements3. Site specific locations powered by only wind, hydro or solar PV has great potential to reduce CO2 emissions4. A BROAD Power-efficient Chiller is more efficient than traditional electric chillers5. A BROAD Packaged Water Distribution System is more efficient than traditional distribution systems6. A BROAD Power-efficient Chiller can be combined with a BROAD CHP system, which has higher
efficiency and energy flexibility than a non-hybrid or single energy source plant

The compressor compresses 7℃ low-temp. & low-pressure refrigerant vapor to 45℃ high temp. & high pressure vapor
then flows into condenser. In condenser cooling water absorbs the heat from refrigerant vapor condensation process
and its temperature raises from 30℃ to 35℃. Then the heat will be discharged to air through cooling tower. After
condensation, 33℃ refrigerant becomes into 6℃ low-temp. & low-pressure liquid after throttle valve. The refrigerant
enters evaporator and evaporates immediately. It absorbs heat from the chilled water and makes chilled water drop
from 12℃ to 7℃. After evaporation, the refrigerant gasifies into 7℃ vapor and sucked into compressor. Then next
cycle begins

COP= cooling capacity%/electricity consumption%×rated COP
e.g.C90 rated COP is 6.2,chilled water temp. is 7℃ ,cooling
water temp. is 26℃ ,then cooling capacity is 100%, electricity
consumption is 87%, COP=100%/87%×6.2=7.12

Machine Room Construction Transportation Tips
BROAD Packaged Power-exfficiency Chiller can be
placed outdoor directly, no additional construction of
machine room. Make the foundation in accordance
with the drawings
· Please refer to dimension drawings for plinth dimensions
· Load capacity:
①The machine room foundation load is recommended
as 1.5 times of the operation weight
②Make sure that the foundation is level without
sinking or overload(for rooftop installation)
③Chiller load should be evenly distributed on the
contact surface between the frame base rolling
steel and the plinth
· Anchor bolts:
①Anchor bolts must be pre-installed in foundation
per dimension drawings
②Place the chiller on the foundation directly and fix
it with anchor bolts
Machine Room Shipping Status
Foundation
Machine room built by customer
· Ventilation: poor ventilation leads to high humidity
in the machine room, which may erode the unit.
Please ventilate 3X machine rooms every hour
· Drainage:
①Chiller foundation must be on a high level in the
machine room
②All discharge pipes and drainpipes must be visible
above the drainage
③Machine room in basement must be built above a
water ditch, which is equipped with an auto level-
controlled submerged pump
· Temperature:
machine room temperature must be controlled
within 5~43℃. Lower temperature may crack heat
exchange tubes and water box when the chiller is
shut off. Higher temperature may damage electrical
components. Thermometer and over temperature
alarm must be installed in machine room
· Humidity:
machine room humidity must be lower than 85%. Higher
humidity may impair insulation of electrical components
· CY35 & CY90 are to be shipped in one piece, while
CY180 & CY400 in two pieces
· Al l equipment can be container ized as per
Container Arrangement Reference
· BROAD can arrange transportation and insurance
on behalf of customers. If customers manage it by
themselves, please refer to BROAD Chiller Packing &
Transportation Regulations for container arrangement
in advance, so as to make sure safety transportation

Lifting & Leveling Tips
Sketch of lifting
<90°
<90°<90°
<90°
<90°
1. Before the chiller is positioned, concrete foundation
plinths must be molded and leveled. The level degree
is <1.5‰, height of foundation is 100~200mm. Then fix
the chiller with anchor bolts on the foundation
2. Lifting must be done by qualified lifting companies
that are properly insured
3. The crane must be supported by crossties and
firm foundation to prevent it from sinking. Check
the crane steel ropes and hooks before lifting to
prevent any accident. The lifting intersection angle
must be less than 90°. It is strictly prohibited to lift
the chiller with a single steel rope. When the chiller
is lifted 20mm above the carriage or the ground, it
should be kept for a little while. Lift the chiller slowly if
everything is fine
4. If l imited by loading height, loading angle or
machine room access, the professional l ifting
company must make special plan with BROAD team
together to avoid any risk
5. The landing of the chiller must be with care. Crash
landing is strictly forbidden
6. When moving the chiller, only round steels or thick
steel tubes can be used as rollers instead of wooden
sticks. Only drag the dragging hole on the rolling
steel. Do not place forces on other part of the
chiller. Lift the unit first with jacks under the rolling
steel before rigging
7. After chiller positioning, please adjust leveling and
lay thin steel plate where it is uneven to guarantee
compact contact between the chiller and base.
Take tube sheet as the leveling point and make
front/rear and left/right leveling (check level height
of every part by acrylic tube). It should be leveled
within 1‰ both lengthwise and sidewise. Leveling
must be done within 2 hours after locating the chiller;
otherwise the chiller base will be damaged
8. The chiller must be located levelly and its steel frame
bases must match the plinth, the weight of the chiller
must be evenly balanced on the plinth
9. The chiller should be protected by full time personnel
during transportation & installation. No access
for unauthorized persons. Valves of the chiller are
forbidden to be screwed. If the machine room is
still under construction, precautions are essential to
avoid chiller get damaged or dirty. No scraping the
paint or insulation layer
