BLOWER SECTION The blower shall be a belt driven centrifugal type, double width, double inlet and shall be statically and dynamically balanced at the factory as a complete assembly to a maximum vibration level of two mils in any plane. The blower wheel shall be a maximum of 15 inches in diameter.. The blower wheel shall be supported on a heavy steel shaft having self-aligning ball bearings with a minimum life span of 100,000 hours. The blower wheel shall be driven by a motor on an adjustable slide base. The drive motor shall be 1750 rpm. The drive package shall be belt driven with two (2) belts and variable pitch sheave sized for 200% of the fan motor horsepower. The blower shall be located to draw air over the coil to insure even air distribution and maximum coil performance. FILTER CHAMBER The fi lter chamber shall be an integral part of the system, designed within the frame and cabinet. The fi lters shall be four inch (4”) deep pleated design, rated not less than 30% effi cient (based on ASHRAE Std. 52.1-1992). ELECTRIC REHEAT The reheat shall be of the fi nned enclosed, sheath type, fabricated of stainless steel core sheath with plated fi ns to withstand moist conditions. The reheat shall be installed on the air discharge side of the cooling coil and shall have three (3) stages. Each stage shall be ___ kW. The total kW shall be ___ to operate on a supply of ____ volts. HUMIDIFIER The unit shall be provided with steam generator type humidifi er. The steam generating humidifi er shall be of the self-contained disposable cylinder type with electronic controls. The capacity shall be adjustable from 10 to 30 pounds per hour. Power consumption at 22 pounds per hour shall be 7.7 kW or less. The humidifi er shall discharge pure steam with no material dust carryover and have a self-regulating automatic fl ush cycle. Cylinders shall be disposable not requiring cleaning or maintenance. The humidifi er fi ll level, water conductivity and fl ush rate shall automatically adapt, both in frequency and duration, to variations in the incoming water. WATER SENSOR DATA AIRE SERIES 6 to 30 ton DX units Guide Specifi cations, continued Units shall be provided with one (1) water sensor. The solid state water sensor shall be mounted under the unit to sense the presence of water. The sensor shall be connected to the microprocessor panel and activate an audible alarm. The water detector shall become an integral part of the microprocessor panel and shall display “WATER DETECTED IN UNDER FLOOR AREA” message when the sensor is activated. 64
DATA AIRE SERIES 6 to 30 ton DX units Guide Specifi cations, continued Data Aire Data Alarm Processor III ( DAP TM III) The environmental system shall be furnished with a microprocessor based Data Alarm Processor-III panel. The panel shall include unit switching functions and display normal functions, malfunctions, and service diagnostics on a 2 row, 80 character, backlit liquid crystal display (LCD) in a clear vernacular format. The panel shall allow recall and display of the high and low temperature for the last 24 hours, high and low humidity for the last 24 hours, current percent of capacity and average percent of capacity for the last hour of operation for cool 1, cool 2, reheat, humidifi cation, and dehumidifi cation, component runtimes for fan motor, reheat, humidifi cation, and dehumidifi cation. Programming shall have multilevel password access to prevent unauthorized access. Programming shall be accomplished entirely from the front of the unit without the need to access, set, or program switches inside the unit (front door of unit does not need to be opened). Programmable functions shall be entered on fl ash memory to insure program retention should power fail. The historical data base shall be maintained by battery backup. Multiple messages shall be displayed by automatically scrolling from each message to the next. Alarm conditions, in addition to being displayed, shall enunciate an audible alarm. A summary alarm relay shall be available for remote alarms. Additional test or service terminal shall not be required for any functions. The control shall include temperature anticipation, moisture level humidity control and automatic fl ush cycles. An alarm condition shall continue to be displayed until the malfunction is corrected. Multiple alarms shall be displayed sequentially in order of occurrence and only those alarms which have not been acknowledged shall continue to sound an audible alarm. The Data Alarm Processor-III panel shall perform an automatic self-test on system start-up. A user accessible diagnostic program shall aid in system component trouble shooting by displaying on the unit LCD screen the name of the controlled item, output relay number, terminal plug and pin number for each controlled item. The following automatic control functions shall be included: Selectable water under fl oor alarm action Start time delay Sequential load activation Humidity anticipation Dehumidifi cation lockout Compressor short cycle Automatic reheat element rotation Automatic or manual restart Energy saver (glycol operation)* Auxiliary chilled water operation* Hot water coil fl ush cycle* Chilled water coil fl ush cycle* Energy saver coil fl ush cycle* DX activation on Energy Saver system* The following conditions, data and normal functions shall be monitored and displayed: Temperature setpoint Humidity setpoint Current temperature Current humidity Cooling Dehumidifi cation Reheat Current percentage of capacity utilized Humidifi cation Current discharge temperature* Chilled water temperature* The following switching and control functions shall be included: System On/Off switch Menu selection buttons Menu exit button Select buttons Manual override for: Alarm silence button blower, cooling, reheat 1, humidifi cation, water valve 65
