4 1 Packaged non-electric chiller (non-electric chiller + water distribution system) The absorption principle cooling water chilled water 7/14 hot water 80/60 hot water pump chilled water pump cooling water pump auto chemical dosing water softner condenser low temperature generator (LTG) high temperature generator (HTG) absorber evaporator high temperature heat exchanger heat source or fuel low temperature heat exchanger The cooling principle The input heat energy heats LiBr solution to generate vapor, then vapor can be condensed into water. When the water enters evaporator (in high vacuum conditions), the temperature goes down immediately. And it is sprayed over the tube to make cooling. When the water absorbs heat from air conditioning system it can evaporate and then can be absorbed by concentrated LiBr solution. The cooling water removes the heat and release into the air. Diluted solution is pumped to HTG, LTG separately to be heated again, generate vapor contimuously that s the cooling cycle.

5 2 chilled water 65/55 hot water 80/60 hot water pump chilled water pump high temperature generator (HTG) heat source or fuel The heating principle Input energy heats the LiBr solution. The vapor produced by the solution heats the heating water in tubes, while condensate returns to the solution to be heated and the cycle repeats. If separate heating is utilized, the heating cycle of the DFA chiller/heater becomes very simple, just like a vacuum boiler. A separate heat exchanger can provide dedicated hot water while cooling operation and heating operation are stopped.

9 6 Model selection and ordering Function selection BROAD chillers are classified as standard type (cooling-heating-hot water),a/c type (coolingheating) and cooling only type. An extra boiler is to be equipped to meet the excessive heating requirement when heating load exceeds 1.3 times of cooling load. Fuel selection Different fuels matches different burners. Fuels apply to a DFA can be: natural gas, town gas, LPG, bio-gas, industrial waste oil, waste foodstuff oil, and light oil. Natural gas and waste heat are of priority. Apply to dual fuel of oil and gas (for special order) Load selection If equipped with low position indoor units (fan coils), suggested cooling load as follows: Residences, hotels and office buildings: W/m2 Shopping malls, restaurants and campuses: W/m2 Theaters, exhibition halls and airports: W/m2 Model selection is mainly determined by required cooling load. If heating load is not enough to meet requirement, an oversized HTG should be selected. Quantity The fewer units, the lower initial investment and operation cost (as the chiller s COP will be higher and water system s electric consumption will be lower at part load). 2 sets are recommended for one system (the sum equals to required load).no need to have standby unit. One unit for buildings that allow chiller stop once a year. Flowrate selection BROAD water distribution system adopts a large temperature difference and low flowrate design so as to save greatly the power consumption. BROAD designs the water head according to experiences of numbers of installation. If the water head is proved to be insufficient, BROAD will enlarge the pump free of charge. Pressure selection The rated pressure limit for chilled/heating water is 0.8MPa, MPa for high-pressure type, and three categories for extra high-pressure type: MPa, MPa, and MPa. System of pressure limit MPa adopts high-pressure type, and for system of pressure limit MPa, economical and technical consideration should be taken to decide if to adopts the extra high-pressure type or secondary heatexchange instead. For extra high building, users need to calculate the pressure of cooling water system and chilled water system separately. Split shipment If limited by access of customers machine room (or limited by container transportation), you can choose split shipment. The chiller normally will be divided into two pieces as Main Sell and HTG. BROAD technicians will connect 3 pipes at the job site. Customers need to prepare welding equipment, nitrogen and provide necessary cooperation. Control The standard BROAD chiller and its water distribution system are equipped with complete control function, enabling internet monitoring. If a building automation system (BAS) has been used, the BAS control interface should be selected optionally. If the BAS interface is not ordered along with the chiller, it can be purchased later. BROAD BAS (building automation system) is highly recommended. Machine room location On the floor or on building top. If limited by facilities, the chiller and the pump set can be installed in basement while cooling tower on the floor, on stilt or on building top. Metal machine room does not apply to basement installation. The chiller and pump set are installed in the same machine room so as to reduce pipe lines. Shipment time BYZ150: 2-6 months BYZ200-BYZ400: 4-8 months BYZ500: 8-12 months Price term BROAD insists on fair and open price policy, the prices stated in this catalog are the standard prices.

39 36 Machine Room Construction Machine Room packaged machine room has ventilation,machine room temp. control, humidity control and drain functions. the machine room built by customers should notice: Ventilation: poor ventilation leads to high humidity in the machine room, which may erode the unit. So serious attention should be paid to ventilation in the machine room. Please ventilate machine rooms every 4 hours and make up the combustion air. The volume of combustion air for a DFA is estimated at 1.3 m3 for every kw fuel. Drainage:1. Chiller foundation must be on a high level in the machine room.2. All discharge pipes and drain pipes must be visible above the drainage.3. Machine rooms 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 C. Lower temperature may crack copper 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. Foundation Please refer to dimension drawings for plinth dimensions. Load capacity: 1. The machine room foundation load is recommended as 1.5 times of the operation weight. 2. Make sure that the foundation is level without sinking or overload (for rooftop installation). 3. The load of a chiller is evenly distributed on the contact surface between the frame base rolling steel and the plinth. Anchor bolts: 1) Chiller can be placed on the foundation directly without bolts (if there is a strong quake source or special anti-vibration requirement, please specify in a purchase order). 2) Anchor bolts must be pre-installed for pumpset foundation per dimension drawing. Service space Recommended Service Space: 1000 service space F tube service clearance 1300 G Remarks: mm model F G If the machine room is smaller than the above size, please contact BROAD for a solution. 2. F, G is the tube service clearance that can use space of water pumps, doors or windows and can also be shared by 2 chillers. 3. It is recommended that the height of the machine room be 500mm higher than that of chillers.

40 37 Piping System Gas System: The standard pressure is 16-50kPa. Lower or higher pressure can be accommodated for special orders. Drain valve should be installed at the lowest part of gas pipes. All connecting pipes must be cleaned and tested for air tightness with 0.6Mpa air when gas piping system is completed. When two or more units are connected in parallel, a buffer pipe (with diameter 3-6 times of the main pipe) must be installed at the main pipe to avoid flameout due to gas low pressure caused by simultaneous startup. Manual drain valve should be equipped at the bottom of the buffer tube. Customers are required to inform BROAD of the fuel type, heating value and pressure so that a burner can be properly selected and the gas pipe diameter can be notified to customers. Then customers can design filter, flow meter, ball valve, diffuser tube and pressure meter. BROAD is responsible for installation of valve trains within supply scope. External gas piping system is to be installed by customers to 1m distance from the burner. The ball valve of BROAD gas valve train must be closed if customers need to test piping pressure so that gas train valve will not be damaged by high pressure. A gas leakage alarm (acting value must be set 20% lower than danger value lower limit) must be equipped in machine room and it must be linkage controlled with draft fans. Machine room must be well ventilated all the time. Oil System Oil system includes oil storage tank, oil pump, daily oil tank, oil filter and metering instruments. Oil tank should be equipped with oil check nozzle, air vent (breather valve), oil refill valve, oil level sensor and drain valve. The lowest oil level of daily oil tank must be 0.1m higher than the burner. Oil pipe should be copper pipe or seamless steel pipe and leakage test should be taken at 0.8MPa min. Medium filters are to be installed at inlet and outlet of oil storage tank. The filters should have enough section area, and should be convenient to install/uninstall and drain. Oil tank should be equipped with precision metering device. Steam System The supply of the steam should be pressure-stable. The upper limit should not be over 110% of the rated pressure. If the pressure may exceed the upper limit, a regulating valve should be equipped in the pipeline. Safety valve should be fixed in the steam inlet pipeline. The protection value is adjusted as 110%-130% of its working pressure. The safety valve should be connected to outdoor to avoid the overpressure of the system. Condensed water should be able to drain smoothly. Condensed water can be stored in an open tank beside the chiller, and then pumped back to the boiler by a condensed water pump or steam trap pressurizer. Water System The initial filling of the chilled/heating water must be with soft water. The leakage rate should be less than 10% every year, or else large amount of city water makeup will cause water system fouling. Minor leakage in chilled/heating water system is made up from the expansion water tank. An open expansion water tank instead of a closed expander is recommended for pressure balance. The water expansion volume is calculated as 4% of total water volume in the system. Chiller, pump set and cooling tower should be in one to one correspondence to achieve more energy saving. BROAD packaged chiller (pumpset) has introduced auto chemical dosing system to solve the conventional problems with cooling water system such as corrosion inhibiting and biocide, especially legionnaire killing. When the distance between cooling tower and machine room is 30m, the cooling water pipe diameter can follow the dimension drawing. If it s 30-90m, the pipe diameter shall be one size larger. If it s > 90m, the pipe diameter shall be two size larger. In water system, big filters with section area 8-15 times larger than pipe section area instead of Y-shape filters shall be used to minimize the water resistance. Soft connector must be installed at inlet/outlet of chilled/ cooling water and hot water system. The weight of the external piping system can never be borne by the chiller. The installation site of the cooling tower should be far from heat source and power, especially should be at least 6m far from the chimney, or the chimney should be 2m higher than the top of the cooling tower. Otherwise the exhaust may access the cooling tower and cause corrosion to copper tubes inside the chiller. Piping requirements: all pipes and valves should not go across the space above the chiller to avoid chiller damage caused by pipe installation, maintenance or leakage. Secondary heat exchanging hot water system is recommended for areas with very hard water. Exhaust System It is recommended independent stack be used for each chiller. If chillers have to share a common stack due to space limitation, the shared stack must be inserted type and the main stack must be bigger and higher to avoid any interference from each other. Exhaust motor valve shall be installed for each exhaust path to avoid corrosion caused by exhaust entering into chillers that are not in operation. The exhaust volume is dependent on the fuel heat input. It is estimated at 1.55m³ per kw fuel input. 3-5m/s flue gas flow velocity in the stack is recommended. Fouling collector should be installed at flue duct inlet to the chiller to prevent condensate from flowing directly into the chiller. The indoor flue duct must be insulated. For high outdoor steel exhaust stack, insulation shall be done to maintain the up force of flue. No insulation is required for low outdoor steel exhaust stack. Try to locate the exhaust outlet as far as possible from the cooling tower, or 2m higher than the cooling tower. Otherwise the flue gas may get into cooling tower and damage the chiller. The rated exhaust temperature is 160 C. However, selection of insulation materials and design of fire isolation area should be based on 300 C temperature for safety concern. An example of exhaust system Vent system is included in machine room supply if BROAD packaged chiller system is ordered

44 41 Transportation Guide Shipping status BY20 is to be shipped in one piece, while BY50 in two pieces. BY chiller, pumpset and cooling tower are to be shipped separately. BY75-400: pumpset and control cabinet are to be shipped in one piece. BY : pumpset and control cabinet are to be shipped in three pieces (A/C water pumpset, cooling water pumpset and control cabinet) All equipment can be containerized. Container transportation regulations is available for reference. Chillers BZ150, BE150, BS250(Max. width 3m) by railway in single piece, chillers BZ250,BS300,BE200 (Max. width 3m, weight 32ton) by vehicle in single piece. Other units will be in 2-6 pieces delivery. If limited by site space or machine room access, small unit can also be split shipment (or split with steel frame), or steel-joint split shipment (i.e. the main shell and HTG are split and soldered by steel plates, which will be cut off before entering the machine room). When the unit reaches the machine room, the split pieces need to be connected by BROAD welders. The customer needs to prepare welding equipment, nitrogen and other necessary cooperation. Solution is charged into the chiller when a unit is shipped in one piece, and packed separately for split shipment or for single-piece shipment with unit shipping weight over 32 tons. BROAD can arrange transportation and insurance on behalf of customers. If the customer chooses to arrange by themselves, please refer to BROAD Chiller Transportation Regulations for container arrangement and safe transportation.

45 42 Lifting and Leveling Tips Lifting must be done by qualified lifting companies that are properly insured. 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 life 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 OK. The landing of the chiller must be with care. Crash landing is strictly forbidden! As the unit is a vacuum device, any impact on the chiller is strictly forbidden! 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. Both sides of HTG and main shell must be lifted simultaneously. Before the chiller is located, concrete foundation plinths must be molded and leveled. Then locate the chiller without bolts. (If there is a strong vibration source or a special anti-vibration requirement, it should be stated before ordering). The pumpset shall be fixed by anchor bolts. The foundation must be level and solid to make sure no sink or overload (when the unit is installed on the roof). For multiple chillers of split shipment, please make sure the original matching between HTG and the main shell. Please locate the chiller according to chiller joint drawing and make sure the joint gap is less than 1.5mm. After chiller locating, 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 lucent tube). It should be leveled within 0.8/1000 both lengthwise and sidewise. Leveling must be done within 2 hours after locating the chiller, otherwise the chiller base will be damaged. 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. Otherwise, the chiller may be twisted slowly, which will finally result in damage due to leakage. The chiller should be protected by full time operators during installation. No access to the chiller or valves for unauthorized persons. Valves of the chiller are forbidden to be screwed. If the machine room is under construction, protective measures are needed to avoid damage or dirt to the chiller. Do not scrape the paint or insulation layer.
