Marvair DC Free Air HVAC Unit with 48 VDC Evaporator Fan Motor, 100% Free Cooling and CoolLinks™ Controller 8.8 to 17.7 kW (30,200 to 60,350 BTUH) Models ASDCA36-42-48-60-72
General Description The Marvair® DC Free Air HVAC units are designed to cool telecommunications shelters where the high internal heat load requires year round cooling-even when ambient temperatures are below 60°F (15°C). To provide cooling during a wide range of ambient conditions, the ASDCA air conditioners have the necessary controls and components for year round cooling. The units use the non-ozone depleting R-410A refrigerant. DC power provides emergency cooling/ventilation Should there be loss of power to the site, the Marvair DC Free Air unit will continue to cool/ventilate the site by utilizing the shelter’s DC power to introduce outside air into the shelter for free cooling. The DC Free Air unit will continue to ventilate the site and extend the run time of the equipment until battery power is exhausted or, at the minimum, owner specified pull down of battery drain.
ASDCA36
The ASDCA models operate on both AC and DC power. The compressor, condenser fan motor and electric heat operate on AC power, but the evaporator motors, the 100% free cooling economizer damper and the internal control board operate on DC power – an inverter is not required. Since these key components are all powered by 48 VDC – the same 48 VDC power used by the shelter’s radios- they are always operational. The 48 VDC power supply connects to an internal DC breaker. From this breaker, power is supplied to the DC indoor blower and control board. Free Cooling with the Marvair 100% Full Flow Economizer When the outside air is cool and dry, the economizer damper opens and draws in filtered, outside air to cool the shelter. The Marvair 100% full flow economizer means the same CFM of outside air is brought into the shelter as the rated air flow of the unit. The innovative design of the full flow economizer assembly also allows outside air to exit the building – pressure relief- when the full flow economizer is operating. This design eliminates the need for additional, costly penetrations in the shelter. Free cooling provides temperature control, energy savings, and increased reliability by decreasing the operating hours of the compressor and the condenser fan. To insure proper operation and optimum performance, all economizers are non-removable, factory installed and tested. Safety Listed The ASDCA air conditioners are built to UL standard 1995, 3rd edition and CAN/CSA C.22.2, No. 236, 3rd edition. For energy efficiency and performance, the units are tested and rated in accordance to the ANSI/AHRI (Air-Conditioning Heating and Refrigeration Institute Standard 390-2003 (Single Package Vertical Units). All units meet or exceed the efficiency requirements of ANSI/ASHRAE/IESNA 90.1.2007. The ASDCA units are commercial units and not intended for residential use. 50Hz. units are for export only. 1

PLC controller The Siemens PLC-based CoolLinks controller sequences the operation of the two Marvair ComPac II units to ensure the most energy-efficient conditioning of the shelter space and the most balanced use of the conditioning equipment. The CoolLinks system determines the need to cool or heat the shelter based on an indoor temperature sensor and outside temperature/humidity sensor connected directly to the controller. When cooling or heating is required, the controller selects the unit that was not running in the previous cooling/heating cycle. This lead/lag operation ensures that each unit receives equal runtime and therefore extends the operating life of the units. In the event that one of the units is unavailable, for example, scheduled maintenance, the system will automatically select the active unit. Similarly, if the internal shelter temperature continues to rise/fall, the system will run both units. For cooling requests, the CoolLinks controller first examines the external shelter conditions to establish whether DC Free Cooling is possible. If acceptable, the 100% full flow economizer damper on the lead unit is opened to 100%. The damper then modulates its position, regulated by the controller, to cool the shelter to the target set point. During extreme cold outdoor temperatures this prevents “shocking” the equipment in the shelter. For units installed in corrosive environments, e.g., near the ocean, the economizer cooling function can be disabled to prevent the entry of corrosive air into the shelter. If DC Free Cooling is active on one unit and the internal temperature continues to rise, DC Free Cooling will then be activated on the second unit. Should the temperature continue to rise, the DC Free Cooling will be disabled on both units, both economizer dampers will be closed, and mechanical cooling activated on the lead unit. The control scheme allows the CoolLinks controller to make as efficient use of the external air as possible to minimize HVAC power consumption. The CoolLinks controller communicates with the Marvair air conditioners over Ethernet. Should communications between the controller and one of the units fail, the unit will continue to run in stand-alone mode and cool to a mixed-air set point of 55°F (12.8°C). Whenever communications are restored, the CoolLinks controller will assume control of the air conditioner. An Ethernet connection is also provided for a SNMP interface through which the Network Operations Center can receive traps (alarms), monitor/change cooling and heating set points, and monitor HVAC unit and system operational parameters. Air Conditioner Alarms and Lockouts Each air conditioner is monitored over Ethernet and if a problem is detected, an alarm is generated. The alarm is displayed on the CoolLinks PLC in the shelter and sent via SNMP trap to the network operations center. • High Pressure Alarm – the refrigerant pressure has exceeded the set point pressure once in a cooling cycle. The air conditioner will continue to operate, but notification is sent that there is a high pressure fault. • High Pressure Lockout Alarm - the refrigerant pressure has exceeded the set point pressure twice in a cooling cycle. The air conditioner will shut down and notification will be sent that there is a high pressure lockout. • Low Pressure Alarm – the refrigerant pressure has dropped below the set point pressure once in a cooling cycle. The air conditioner will continue to operate, but notification is sent that there is a low pressure fault. • Low Pressure Lockout Alarm - the refrigerant pressure has dropped below the set point pressure twice in a cooling cycle. The air conditioner will shut down and notification will be sent that there is a low pressure lockout. • Damper Alarm – if the 100% full flow damper does not open when required, an alarm notification is sent that the damper is not open. The damper is exercised every 24 hours to verify proper operation. • Dirty Filter Alarm – a switch monitors the pressure on either side of the filter. If the differential pressure exceeds the set point pressure, an alarm notification is sent that there is not sufficient air flow through the filter. • Communications Alarm – a signal is sent if there is a loss of communication between the air conditioner and the CoolLinks controller. • Landline Power Alarm - If either air conditioner loses landline power, an alarm notification is sent.

Shelter & System Alarms In addition to the HVAC alarms, the CooLinks controller also provides Shelter and System alarms. The alarm is displayed on the CoolLinks PLC in the shelter and also sent via SNMP trap to the network operations center. • First Stage High Temperature Alarm – Inside temperature above 85°F (29.4°C). • Second Stage High Temperature Alarm – Inside temperature above 90°F (32.2°C). • Low Temperature Alarm - Inside temperature is below 45°F (7.2°C). • Smoke Alarm - If the smoke sensor input to the CoolLinks system is active, the Compressor, Heater, and Indoor Blower Motor on both HVAC units will be shut down and the damper will closed completely. This will stop air flow within the shelter. • Hydrogen Detector Alarm- If the hydrogen sensor input to the CoolLinks system is active, the damper(s) on units that are not currently in mechanically cooling will be fully opened and the Indoor Blower Motor(s) will be turned on. This will expel noxious gases and introduce outside air into the shelter. If one unit is in mechanical cooling, it will continue to run. The other air conditioner will turn on and operate in the emergency ventilation mode. • Generator Operation Alarm - If the generator running input to the CoolLinks system is active, only one HVAC unit will be permitted to run in mechanical cooling. As the generator is typically sized to run only one HVAC unit, this ensures that the generator load is not exceeded.
Remote Access Data Points Through the Ethernet connection, the network operations center can monitor and change various data points in the HVAC system and the shelter.
Data Points which can be monitored and changed: • First Stage Cooling Set Point Temperature • Second Stage Cooling Set Point Differential Temperature • First Stage Heating Set Point Temperature • Second Stage Heating Set Point Differential Temperature
Data points which can only be monitored: • Inside Temperature - Current • Outside Temperature - Current • Outside Humidity - Current • Dew point - Current • Inside Temperature - Average Last Hour • Outside Temperature - Average Last Hour • Outside Humidity - Average Last Hour • Dew point - Average Last Hour • Unit 1 & Unit 2 Mechanical Cooling Time - Last Hour • Unit 1 & Unit 2 Mechanical Cooling Requests - Last Hour • Unit 1 & Unit 2 DC Free Air Cooling Time - Last Hour • Unit 1 & Unit 2 DC Free Air Cooling Requests - Last Hour • Unit 1 & Unit 2 Heating Time - Last Hour • Unit 1 & Unit 2 Heating Requests - Last Hour
Dry Contact Alarm Outputs A dry contact is provided for each HVAC unit to indicate HVAC unit failure to the shelter alarm block. Unit failure is defined as 1) a high pressure lockout or 2) a low pressure lockout or 3) a loss of landline power.This dry contact is a normally open contact.
