    What are the typical uses for an EcoAisle System

    Product line:

    Environment:  
    Only ACRC100, EcoBreeze, ACRC301X

    Cause:

    Resolution:  
     

    •         Predictable cooling solutions are designed for close temperature control. They provide high reliability for year-round operation, with the ease of service, system flexibility, and redundancy necessary to keep the technology room up and running 24 hours a day.

    •         The maintenance of temperature conditions is critical to smooth operation of a data center. Temperature control is essential because fluctuations in the temperature of a data center can cause thermal stresses and premature failure in IT equipment. Separation of the aisles with heat removed directly from the hot aisle and directly into the cold aisle, ensures that the inlet temperatures to the equipment will be constant and adequate for proper operation.

    •         As blade servers become a more relied upon server platform, new cooling problems arise in the data center. The EcoAisle allows for more predictable cooling in this new IT environment by separating the hot and cold airstreams in the IT Environment.  The solution ensures that the supply and return air streams are channeled to their required locations.

    •         Capacity planning is yet another benefit of the EcoAisle. In an open aisle / row configuration the cooling system is typically oversized compared to the power consumed by the IT load.  The efficiencies gained with deploying a containment system enables the cooling capacity to be closely matched with the power.  The deployment of the Active Flow Controller more closely couples the cooling equipment to the IT heat load as it monitors the pressure inside vs outside the containment allowing the fan speed to be adjusted so that the right amount of air is being provided.  This could also result in shutting units off as they may not be needed when the containment is deployed.  The matching of cooling to power is what we refer to as rightsizing.

    •         As the loads change, the demand for cooling will increase or decrease.  Typical data center cooling looks at the temperature of the room to adjust capacity.  The method of relying solely on temperature control could be flawed depending on the placement of the temperature probe.  The Active Flow controller looks at the pressure inside vs outside the aisle allowing it to quickly detect the dynamic load changes and send a control signal to adjust the airflow of the cooling equipment.  This quick response to the changing environment will allow the protection of expensive IT assets.

    •         Floor space utilization is another benefit of the EcoAisle.  The efficiency gains in the cooling system when the EcoAisle is deployed reduce the number of cooling units in the solutions.  Reducing support infrastructure to the IT equipment results in more usable space for deployment of IT assets.  The EcoAisle can easily be retrofitted into existing datacenters, allowing greater cooling capacities without adding more cooling units.

    NetworkAIR FM DewPoint Control Explanation

    FM
     
    Environment:
    Data Center Cooling
     
    Cause:
     
    Resolution:
    When the FM systems belong to a group, humidity is managed using dewpoint control. Humidity readings and setpoints are shown in %RH but are converted to dewpoint internally for control.  Dew point is a function of both temperature and humidity so you must take temperature into account when calculating humidification demand.

    The dew point temperature setpoint for humidification is calculated from the humidification setpoint and the reheat setpoint (use cooling setpoint if reheat is not present). The dew point of the room is calculated from the return humidity and the return temperature.

    The dew point temperature setpoint for dehumidification is calculated from the dehumidification setpoint and the cooling setpoint.

    For example, if the reheat setpoint is 68 F and the humidification setpoint is 50%, the dew point setpoint is 49 F. If the room temperature is 74 F and the return humidity is 40% the dew point of the room is 48 F.

    The humidifier demand is calculated as the difference between the actual room dew point and the desired room dew point divided by the sensitivity.
    So in this example; Demand = (49 - 48) / 2 = 0.5 or 50% demand. So the humidifier output will be about 50%.

    There is one other note. Versions of the FM controller firmware v6.7.0 and earlier do not calculate low and high humidity alarms correctly. This has been corrected in version 6.11.0 which has just been released. I'm in the process of putting the new version on the firmware download page of apc.com, but if you can't wait, send me an e-mail and I'll forward it to you.

    For Example:
    COOL SETPOINT / DEHUMID SETPOINT = DEWPOINT HIGH LEVEL
    REHEAT SETPOINT / HUMID SETPOINT = DEWPOINT LOW LEVEL

    System Configuration

    The System configuration options are defined both at the factory and during the commissioning of the Modules in the System.

    Caution: Changing the settings incorrectly can cause serious malfunctions and damage to your System. Only qualified service personnel should make changes to these settings.

    Note: Some System configuration settings may not apply to your APC NetworkAIR FM DX Precision Air Conditioner.

     

    System options 

    Path: Main > Setup > System # > System Config > System Options 

    The System Options menu contains settings that identify the hardware installed in this System and the methods used to control that hardware. 

    Mains In. Indicates the primary operating voltage required for this System. The configuration is based on the voltage of the electrical components in the System

    and is printed on the nameplate attached to the door on the right side of the electrical box. 

    Coil Cfg. Indicates the coil configuration installed in the Modules of this System.

    DX—Direct expansion (DX) coil

    Econ—Economizer and DX coils

    MultiCool—MultiCool® (chilled water) and DX coils 

    Humid Ctrl. Indicates the humidity control method. The System can control the humidity based on the relative humidity (RH) of the return air and the dew point (DewPt) of the return air. 

    • Relative humidity (RH): The System activates humidification modes based on the difference between the humidify/dehumidify setpoint and the return humidity value.

    • Dew point (DewPt): The dew point method corrects for hotspots near the environmental sensors, and is calculated from the temperature and relative humidity of the room air.

    – The System activates humidification based on the dew point setpoint and the calculated dew point in the room.

    – The dew point setpoint is calculated from the humidification setpoint and the reheat setpoint. 

    If there is no reheat mode, then the cooling setpoint is used.

    Example. If the reheat setpoint is 20°C (68°F) and the humidification setpoint is 50%, the dew point setpoint is 27°C (80°F). If the room temperature is 23°C (74°F) and the return

    humidity is 40% the dew point of the room is 26°C (78°F). The humidifier demand is calculated as the difference between the actual room dew point and the desired room dew

    point divided by the sensitivity. In this example: Demand = (49 - 48) / 2 = 0.5 or 50% demand. The humidifier output will be about 50%. 

    Note: The System will always use the dew point method when the remote sensor readings are used to control the room environment or if the System is part of a redundant Group. 

    # PCIOMs. Set the number of Programmable Customer Input/Output Modules (PCIOMs) installed in the user interface box. This setting controls the number of input

    contacts and output relays available in the 

    Input/Output menu.See “Contacts and Relays” on page 25 to set up the contacts and relays from the display interface.See the NetworkAIR FM DX 60 Hz

    Installation manual to connect the contacts and relays to the Main Module. 

    # Modules in Sys. Indicates the number of Modules in this System. Up to three Modules can be joined together to work as a single System. 

    Air Filter. Set the type of air filters installed in the Modules of this System to either standard (30-40%) or high efficiency (65-85%). 

    Fast Startup. Set the System to bypass the normal start-up sequence and start-up delay the next time power is applied to the System. 

    Note: The Fast Startup option is not recommended for typical installations. 

    Airflow. Set the airflow pattern for the Modules in this System.

    • Up

    • Down

     Rej. Method. Indicates the method used for heat rejection by the refrigeration system.

    • Air

    • Water

    • Glycol

     Dehum Capacity. The dehumidify mode can be set to use half capacity or full capacity of the cooling coil.

    • Half capacity uses one compressor and half of the cooling coil to dehumidify. Rooms with small heat loads should use half capacity to avoid over-cooling while dehumidifying.

    • Full capacity uses the entire coil and both compressors. When the unit is in dehumidification mode the dehumidification solenoid valve on the secondary liquid line is not energized and remains closed. All refrigerant is directed through the expansion valve which feeds three quarters of the cooling coil. 

    Module Rot. The System rotates the order in which the compressors are engaged to equalize the total number of hours that each compressor runs. Set the number of hours at which to change the order in which the compressors are engaged. A setting of zero indicates that the order in which the compressors are engaged should not be changed. 

    Refrigerant. Set to the type of refrigerant charge used in the direct expansion refrigeration system.. 

    Suction Pressure Compensation. Allows the System to slow the blowers if the suction pressure gets too high. Use this setting if you are using the FM in a high-density application 

    System delays 

    Path: Main > Setup > System # > System Config > System DelaysThe System Delays protect the Modules in the System from excessive wear and damage and keep the modes (cooling, reheat, and dehumidify) from working against each other. 

    Comp Min ON. The delay begins when the compressor engages and then prevents the compressor from disengaging until the delay has expired. It protects the compressors from rapidly cycling between on and off and pushing all of their lubricating oil out into the refrigerant line. 

    Caution: Reducing the Comp Min ON delay can shorten the compressor life by causing excessive wear and damage. 

    Comp Min OFF. TheThe delay begins when the compressor disengages and then prevents the compressor from engaging until the delay has expired. It protects the compressors from rapidly cycling between on and off and pushing all of their lubricating oil out into the refrigerant line. 

    Caution: Reducing the Comp Min OFFdelay can shorten the compressor life by causing excessive wear and damage. 

    Cndsr Vlv Dly. The condenser fluid valve close delay begins when the compressors disengage, and then keeps coolant flowing through the heat exchanger until the delay expires. Once the delay expires, the condenser fluid valve closes. 

    Intrstg Dly. The interstage delay begins when the first compressor (stage 1) in a Module engages. It prevents a second compressor (stage 2) in a System from engaging until the delay has expired. 

    Start-up Dly. The start-up delay begins when the System is started and initialized. The System cannot begin operation until this delay has expired. Use the start-up delay to restart equipment sequentially in your room after a power loss. 

    Mode Dly. The start-up delay begins when the blowers start. It allows the sensors to obtain an accurate reading of the room conditions and it allows the System to check for major alarms before engaging environmental control functions. 

    Communication Loss Shutdown Delay. Set the communication loss shutdown delay. The delay begins when an Expansion Module loses communication with the Main Module of a System. If communication is not restored before the delay expires, the Expansion Module will shut down. Set the delay for up to twenty-four hours, or set the Expansion Modules to continue operating if communication with the Main Module is lost by selecting Disabled. 

    Building management 

    Path: Main > Setup > System # > System Config > Building Management
    If you are using a building management system with your Module, you must set the following values: 

    Address. The address of the Main Module on the RS-485 bus.

    Baud Rate. The baud rate for the RS-485 bus.

    Parity. The parity for the RS-485 bus.

    Stop Bits. The stop bits for the RS-485 bus. See the NetworkAIR FM DX 60 Hz Installation manual to wire the electrical connections of the building management system to the RS-485 bus of the Module. 

    Sensor setup

    Path: Main > Setup > System # > System Config > Sensor Setup

    Specify the set of sensors the Module will use to calculate the environmental control demands.

    Temp/Hum Snsrs. Choose the set of temperature and humidity sensors the controller will use when determining the need for environmental control. The return sensors and the remote sensor string are available.
    Note: Any optional remote temperature and humidity probes installed must be supported by the NetworkAIR FM DX. 

    Dflt Snsrs. Choose the sensor group that the System will use when the System settings are reset to their default values. 

    Rmt Snsr Data. When determining the environmental controls, choose the measurement from the remote sensors for the controller to use.

    Max—Use the maximum value reported by a sensor on the string.

    Avg—Use the average reported values of all of the sensors on the string. 

    Settings for fluid-cooled options

    Modules using the Economizer or MultiCool options have several settings that must be defined. To accommodate the heat of the rejection method, the valve and piping settings must be configured.The following table lists the settings that apply to each type of fluid-cooled option. Refer to the rest of this section for detailed descriptions of each setting: 

     

    Valve types 

    Path: Main > Setup > System # > System Config > Valve Types

     

                                                                                       

    Flow Switch. Set the location of the optional flow switch in this System. The flow switch detects if there is adequate liquid coolant (glycol or water) flow to maintain coil operation. If the flow switch detects inadequate flow in a MultiCool or Economizer coil, it will switch the cool or dehumidify mode to the direct expansion coil. If the flow switch detects inadequate coolant flow at the heat exchanger it will disable the compressors. 

    The Flow Switch setting indicates where the flow switch is installed:

    DX—for the water or glycol line entering the heat exchanger (to maintain head pressure in DX Systems).

    Multi—for the chilled water input to the MultiCool coil or chilled water coil (Systems using chilled water only).

    None—for air-cooled Modules with no MultiCool coil.

    Cndsr Vlv. The condenser fluid valve controls the flow of coolant into the heat exchanger or to the Economizer coil. Set the condenser fluid valve as a three-way valve.

    Note: Economizer valves are always three-way valves.

    Coil Fluid. The coil fluid valve controls the flow of coolant to either the MultiCool, Chilled Water, or Economizer coil. Set the coil fluid valve as a three-way valve. 

    Actuator types 

    Path: Main > Setup > System # > System Config > Actuator Types
                                                                                       

    Cndsr Vlv. Set the type of condenser valve actuator; the actuator can be set as Flt Ctrl or None

    Floating Control maintains the position of the valve when the power is off.

    None indicates that no condenser valve is installed. Air-cooled Systems with no external water piping do not require a condenser valve actuator. 

    Coil Fluid. Set the coil fluid valve actuator to Flt Ctrl, or None. 

    Floating Control maintains the position of the valve when the power is off.

    None indicates that the Module does not have a MultiCool or Economizer coil. 

    Economizer isolation valve (optional)

    When multiple Modules having three-way valves are connected to a common coolant source, coolant flow through a Module exists even when there is no cooling demand. The Economizer (coolant) isolation valve is used in these instances to stop coolant flow through a Module during times of no cooling demand in applications where a variable speed coolant pump is used. 

    Econ Isolator Close Dly

    Econ Isolator Open Dly

    Econ Isolator Valve Enable

    Econ Isolator— mapped to an output relay 

    Path: Main > Setup > System # > System Config > System Delays 

    Econ Isolator Valve Delay: Close. When there is no longer a demand for cooling, the Economizer isolation valve actuator closes the valve. The valve remains open during the close delay, keeping coolant flowing through the coil and the heat exchanger until the delay expires.

    Econ Isolator Valve Delay: Open. When there is a demand for cooling, the Economizer isolation valve actuator opens the valve. The compressors will not engage until the open delay has elapsed.

    Note: If you are using different types of actuators for the Modules in your System, set the open delay to accommodate the valve that takes the longest to open. 

    Path: Main > Setup > System # > System Config > Coil Fluid Options 

    Econ Isolator Valve: Enable. Use this setting to indicate that an Economizer isolation valve is installed in the coolant piping for this System.

    Path: Main > Setup > System # > Input/Output > Output Relays

    Econ Isolator Output Relay. To use the Economizer isolation valve, you must map the ECON

    ISOLATOR event to one of the output relays. When you set up the relay for the Main Module, it will copy the settings to the Expansion Modules. 

    Coil fluid temperature activation threshold and deadband 

    Path: Main > Setup > System # > System Config > Coil Fluid Options 

                                                                                                   

    The Coil Fluid Options help control the optional MultiCool coil or Economizer coil in equipped Systems. Set the temperature threshold and deadband for using the MultiCool coil or the Economizer

    coil. The System will compare the actual coolant temperature with the setpoint and deadband to determine if the coolant is at a temperature low enough to operate the coils. 

    Coil Fluid Temp Activation: Threshold. Set the coil fluid activation threshold. The coolant temperature must be below the threshold to use the optional MultiCool coil or Economizer coil.

    Coil Fluid Temp Activation: Deadband. Set the MultiCool or Economizer activation deadband. The deadband is the sensitivity range above the

    Coil Fluid Temp Activation: Threshold that the coolant temperature can reach before the controller will stop using the MultiCool or Economizer coil. For example, if the threshold is 10°C (50°F) and the deadband is 2.2°C (4°F), then the controller will disengage the MultiCool coil or Economizer coil when the coolant temperature exceeds 12.2°C (54°F) and will not reengage the coil until the coolant temperature reaches 10°C (50°F). 

    Input contacts

    Path: Main > Setup > System # > Input/Output > Input Contacts 
                                                                                                   
    Each Main Module supports up to 16 user-defined input contacts. Each contact monitors a sensor and responds to changes in the state of the sensor (open or closed). 

    Name. Provide a unique name for each input contact.

    Normal. Choose the normal state of the sensor. If the state changes, the controller takes the action defined by the Alarm Map setting.

    Delay. Set how long the contact should be out of its normal state before the controller takes action (controlled by the Alarm Map setting). 

    Action. Set the System controller to respond to the change of status for an input in one of the following ways: 


    Output relays

    Path: Main >Setup >System # >Input/Output >Output Relays 

                                                                                                   

    The Main Module supports up to 16 user-defined output relays. Output relays respond to internal alarms and events by changing states to notify outside devices. 

    Relay Out. Choose the relay number to view or modify.

    Map. Choose alarms or events to map to this relay:

    • The first line of the map field displays the location of the event that is mapped to this relay. It can be a System, Main Module, Expansion Module 1, or Expansion Module 2 event.

    • The second line displays the name of the event mapped to this relay. 

    Note: Any input contact or output relay available in this System can be mapped to this relay.If you have installed an Economizer automatic coolant isolation valve (Econ Isolator), you need to

    map the Econ Isolator event to a relay connected to the isolation valve actuator.Caution: When using the Economizer automatic isolation valve, map only the Econ 

    Isolator event to the relay connected to the valve actuator. See the NetworkAIR FM DX 60 Hz Installation manual for instructions on wiring the relay connection to the automatic isolation valve actuator.

    If you have installed an Economizer automatic coolant isolation valve (Econ Isolator), you need to map the Econ Isolator event to a relay connected to the isolation valve actuator.

    Action.

    The Action field changes as you scroll through the list of events that can be mapped to this relay. Remove indicates that the event is already associated with this relay. Add indicates that the

    event is not associated with this relay. Press the ENTER key and change the setting to map the displayed event to this relay or remove the displayed event from the list of events mapped to this relay.

    Normal. Set the normal state for this relay. If the state of an alarm or event mapped to this relay changes from the normal state, the relay also changes state.

    Reset Mappings. Clear all of the output mappings back to their default setting. 

    Configure Module

    Paths: Main > Setup > Module > Main Module > Module Config > Config Module
