ADVANTAGES OF FLOODED CHILLER In a flooded evaporator the refrigerant surrounds the tubes in the shell and the water to be cooled flows through the tubes. The level of liquid refrigerant in the shell is maintained by the combined action of an electronic level controller and a mod-motor actuated ball valve which modulates the subcooled liquid refrigerant into the evaporator. This ensures that all the evaporator tubes are completely immersed in the liquid refrigerant for better heat transfer efficiency. For a Direct Expansion (DX) evaporator the refrigerant is expanded into the tubes while the chilled water is circulated through the shell. Thermostatic expansion valve is used to throttle the refrigerant in maintaining constant superheat of suction gas to the compressor. The following are the advantages of using flooded chiller:
1. Higher Capacity and Higher EER Achievable with the Same Compressor The flooded evaporator with all the copper tubes immersed in the “boiling” liquid refrigerant enables a small approach temperature between the “boiling” liquid refrigerant temperature in the shell and the outlet chilled water temperature in the evaporator tubes to be achieved. This approach temperature or temperature difference between the evaporating temperature of the boiling liquid refrigerant and the chilled water outlet temperature, for a flooded evaporator, is typically less than 3°F. On the contrary, for a DX or Direct Expansion Evaporator, the typical approach temperature is between 8°F to 10°F. This simply means that the same compressor in a flooded evaporator system will operate at a higher saturated evaporating temperature when compared to the same compressor in a DX-Evaporator system, when outlet chilled water temperatures in both cases are set at the same temperature. Figure 1 shows the typical screw compressor capacity performance curve at a particular condensing temperature over saturated evaporating temperature of between 30°F to 50°F, and the typical power
input curve over the same conditions. It can be noted that the same compressor when operating with a flooded evaporator will generate approximately 8% more cooling capacity while kw input increases negligibly by about 1.8%. Therefore, the same compressor when coupled to a flooded evaporator will typically achieved higher cooling capacity performance with correspondingly higher Energy Efficiency Ratio (EER) i.e. (Btu/watt) or lower kw/Ton.
FIGURE 1
A DX evaporator uses TXV throttling to maintain about 10 to 15°F suction superheat to prevent liquid flood back to the compressor. In a flooded evaporator, the refrigerant boils off in the shell and gas can be sucked out from the top of evaporator back to compressor. The suction superheat is usually about 2 to 3°F. Reduction in suction superheat will further increase the capacity performance of the compressor.

ADVANTAGES OF FLOODED CHILLER
DX evaporators are typically designed with higher tube velocities to ensure proper oil return to compressor both at full load and at reduced load. This will contribute to higher refrigerant pressure drop through the evaporator. On the contrary, there is very little shell side pressure losses for a flooded evaporator. Therefore, lower suction pressure drop in the flooded design will impose less capacity penalty on the compressor and this will further enable the compressor in a flooded evaporator to generate more capacity than one with a DX Evaporator.
2. Better Part Load Performance
The Dunham-Bush Air Cooled Flooded Chiller with its sophisticated advanced controller and patented oil management system has all evaporator tubes completely immersed in the “boiling” liquid refrigerant to achieve superior heat transfer efficiency while ensuring adequate oil return to the compressor(s). This ensures superior full-load efficiency and even better part-load efficiency as the full heat transfer surface areas of the evaporator tubes are utilized even at part-load conditions. On the contrary, in the Direct Expansion Evaporator, because of the need to maintain adequate refrigerant gas velocities in the evaporator tubes for proper oil return, it is typical for certain bundle of evaporator tubes to be “blocked” or “baffled off” at part-load conditions. Thus not utilizing the full heat transfer surface areas of the evaporator tubes and therefore have a lower efficiency when compared with a flooded evaporator chiller at part-load conditions.
3. Excellent Capacity Modulation in
Response to Building Loads Dunham-Bush utilizes its state-of-the-art advanced controller in combination with the electronic level controller and mod-motor actuated ball valve to ensure instantaneous and precise feeding of liquid refrigerant to the flooded evaporator
in response to changes in building demand; and maintains precise (±1/2°F) preset outlet chilled water temperatures even at very low load conditions; whereas most of Dunham-Bush’s competitors, in screw chillers, still utilizes the conventional “centrifugal chiller” method of using orifice plates to modulate refrigerant feed to the evaporator; and as such their machines do not function efficiently at low-load conditions and can encounter oil return problem!
4. Cleanable Evaporator
For a single pass evaporator, the end plates at both ends of the water boxes (2 pass only at return end) can be removed easily without dismantling the chilled water piping connections, for inspection and for mechanical tubes cleaning with brushes or auto-brush. This will enable low tube fouling factor in the evaporator to be ensured, thus maintaining system efficiency.
5. Lower Water Side Pressure Drop
In a DX evaporator, the water flows transversely over the outside of the tubes. The water flow is guided with vertical baffles. This will have a higher-pressure drop as compared with the water flow in the tubes of a flooded evaporator. In other words, the equivalent flooded chiller will require smaller water pump to operate at lower power consumption.
6. Commonly Used In Large Tonnage
Chillers Where Efficiency Is Critical As a general rule, DX-evaporator are typically used in small and medium tonnage chillers where efficiency is not important and the low initial cost is the main consideration! However, with increasing energy cost and the drive to reduce global warming, flooded evaporator chillers will increasingly become more popular not only in the large tonnage but also in the small and medium tonnage chillers. Dunham-Bush, again, leads the industry in this respect!

The controller as standard is additionally equipped with history files which may be used to take logs which may be retrieved via the phone modem or internet connection periodically. Now owners of multiple buildings have a simple and inexpensive method of investigating potential problems quickly and in a highly cost effective manner.
Refrigerating Cycle The refrigerant management system, is very similar to centrifugal water chillers and is shown in the refrigerant cycle diagram below.
Liquid refrigerant enters the flooded evaporator uniformly where it absorbs heat from water flowing through the evaporator tubes. The vaporized refrigerant is then drawn into the suction port of the compressor where the compression begins.
This partially compressed gas is then joined by additional gas from the flash economizer as the rotors rotate past the vapor injection port at an intermediate pressure. Compressed gaseous refrigerant is then discharged into the integral oil separator where oil, which is contained in the refrigerant vapor, is removed and returned to the oil sump.
Fully compressed and superheated refrigerant is then discharged into the condenser, where air is being drawn through the condenser tube by the propeller fan cools and condenses the refrigerant. Liquid refrigerant then passes through the first expansion device and into the flash economizer where flash gas and liquid refrigerant are separated.
The gaseous refrigerant is then drawn out of the flash economizer and into the vapor injection port of the compressor. The remaining
- 7 -
UNIT FEATURES liquid refrigerant then passes through a second expansion device which reduces refrigerant pressure to evaporator levels where it is then distributed evenly into the evaporator.
By removing the flash gas from the flash economizer at an intermediate pressure, the enthalpy of the refrigerant flowing into the evaporator is reduced. This increases the refrigeration effect and improves the efficiency of the refrigeration cycle.
Refrigerant flow into and out of the flash economizer is controlled by modulating valves which eliminate the energy wasting hot gas bypass effect inherent with fixed orifices. Part-Load Performance Through the use of flash economizer modulating flow control and multiple compressors, Dunham-Bush air cooled chillers have best part-load performance characteristics
in the industry when measured in accordance with ARI Standard 550/590-2003.
In most cases, actual building system loads are significantly less than full load design conditions, therefore chillers operate at part load most of the time.
Dunham-Bush air cooled chillers combine the efficient operation of multiple compressors with an economizer cycle and advanced controller to yield the best total energy efficiency and significant operating saving under any load.
When specifying air conditioning equipment, it is important to consider the system load characteristics for the building application. In a typical city, the air conditioning load will vary according to changes in the ambient temperature. Weather data compiled over many years will predict the number of hours that equipment will operate at various load percentages.

TYPICAL SEQUENCE OF OPERATION The Dunham-Bush air cooled water chiller depends mainly on its on-board controller for control. Operation described is for a two-compressor units and is very similar for single, four-compressor units.
For initial start-up, the following conditions must be met:
Power supply to unit energized. Unit circuit breakers in the "on" position. Control power switch on for at least 15 minutes. Compressor switches on. Reset pressed on controller keypad. Chilled water pump running and chilled water flow switch made. Leaving chilled water temperature at least 2°F above setpoint. All safety conditions satisfied.
After all above conditions are met, the controller will call for the lead compressor to start. The compressor 15-minute anti-recycle timer is initiated at compressor start.
The controller monitors compressor amps, volts, leaving water temperature and suction and discharge pressures. The compressor and cooling capacity is controlled by pulsed signals to load and unload solenoid valves on the compressor. When the compressor starts, it is fully unloaded, yielding about 25% of its full load capacity. As the computer gives it load signals, capacity gradually increases. The rate of compressor loading is governed by ramp control which is adjustable in the computer.
The computer responds to leaving chilled water temperature and its rate of change which is proportional and derivative control. If leaving chilled water temperature is within the deadband (+/-0.8°F from setpoint), no load or unload commands are given. If chilled water temperature is above deadband, the computer will continue loading the compressor until a satisfactory rate of decline is observed. If leaving chilled water temperature is below the deadband, the compressor is commanded to unload. Thus the compressor capacity is continuously modulated to match applied load
and hold leaving chilled water temperature at setpoint.
If the applied load is greater than one compressor can handle, it will load fully and then the controller will call for a second compressor. After one minute, the second compressor will start in the same manner as the first. Then both compressors will be commanded to adjust load to 50%. They are gradually loaded up together until the applied load is satisfied. In this way the two compressors share the load equally.
If the applied load decreases to the point that both compressors are running at about 40% capacity, the computer shuts down the lag compressor and loads the remaining compressor to about 80%. If applied load decreases further, the remaining compressor unloads proportionately. If applied load decreases to less than the minimum capacity of one compressor, the leaving chilled water temperature will decline to 2°F below setpoint, at which time the lead compressor will shut down. It will restart automatically if leaving chilled water temperature rises to 2°F above setpoint and both 15 minute anti-recycle and one minute start delay timers are satisfied.
During start-up operation, the computer monitors the difference between discharge and suction pressures to ensure that minimum of 30 psi differential is available for compressor lubrication. If the difference falls below a minimum of 30psi, the computer closes refrigerant flow control valves, starving the evaporator, causing evaporator pressure to drop, increasing differential pressure. This is especially helpful at startup, when warm chilled water and low ambient temperature would cause a low head situation. This feature is called EPCAS: Evaporator Pressure Control at Startup. It is one of several proactive control features of the controller which overcome potential problems while continuing operation. Two additional proactive features are low suction and high discharge pressure override. If operating pressures approach trip level, compressors are unloaded as necessary to continue operation.

APPLICATION DATA Low Ambient Operation / Freeze Protection If unit is required to operate below 20°F (-7°C), optional head pressure control is required. Though heater tape is provided on vessel, all water piping must also be protected by heater tape. Glycol is recommended for added protection. If wind in area is over 5 mph (8 kph), a wind barrier is recommended. Desuperheaters A hot gas desuperheater can be factory supplied for field installation. Tees in refrigerant lines with shut off valves can be supplied. Consult factory for further details. Water Circuit Constant water flow required with a minimum of 3 gallons per ton (3.3 liters / kWo) increasing up to 10 gallons (11 lifers) for process, low load applications with small temperature ranges and/or vastly fluctuating load conditions.
Glycol Freeze Protection If the chiller or fluid piping may be exposed to temperatures below freezing, glycol protection is recommended. The re-commended protection is 15°F (8.3°C) below the minimum ambient temperature. Use only glycol solutions approved for heat exchanger duty. The use of automotive anti-freeze is not recommended because they have short-lived inhibitors and fouling of the vessels will occur. If the equipment is exposed to freezing temperature and not being used, the vessels and piping should be drained. If the equipment is being used for operating conditions below 42°F (5.5°C) with standard vessels or below 40°F (4.4°C) with optional 40°F (4.4°C) vessels, glycol should be used to prevent freeze damage. The freeze protection level should be 20°F (11°C) lower than the leaving brine temperature. The use of glycol causes a performance aerate as shown in table for ethylene glycol and table for propylene glycol and needs to be included in the unit selection procedure.

DIMENSIONAL CLEARANCE SPACE REQUIREMENTS
Single Pit (See Note 2) Double Pit (See Note 2) Multi Pit Corner Wall
Notes: 1.) All dimensions are minimal, unless
otherwise noted. 2.) Pit installations are not re-
commended. Re-circulation of hot condenser air in combination with surface air turbulence cannot be predicted. Hot air re-circulation will severely affect unit efficiency (EER) and can cause high pressure or fan motor temperature trips. Dunham-Bush will not be responsible for ducting fans to a higher level to alleviate the above mentioned conditions.
