Walgreens 5604-R14 June 24 2014 All-aluminum construction improves re-cyclability. Galvanic corrosion is also minimized due to all aluminum construction Strong aluminum brazed structure provides petter fin protection. In addition, flat streamlined tubes also make microchannel coils more dust resistant and easier to clean. Coils shall be leak tested at the factory to ensure the pressure integrity. The evaporator coil and condenser coil shall be leak tested to 600 psig. The assembled unit shall be leak tested to 465 psig. The condenser coil shall have a p�atent pending 1+1+1 hybrid coil designed with slight gaps for ease of cleaning A removable, reversible, double-sloped�ondensate drain pan with through the base condensate drain is standard. Outdoor Fans The outdoor fan shall be direct-drive, statically and dynarr�ically balanced, draw-through in the vertical discharge position. The fan motor shall be permanently lubricated and shall have built-in thermal overload protection. Indoor Fan The following units shall be equipped with a direct drive plenum fan design (T/YSC120E, T/YHC092, 102, 120E). Plenum fan design shall include a backward-curved fan w�eel along with an external rotor direct drive variable speed indoor motor. All plenum fan designs will have a variable speed adjustment potentiometer located in the control box. 3-5 ton units (standard efficiency 3-phase or high efficienc�3-phase with optional motor)are belt driven, FC centrifugal fans with adjustable motor sheaves. 3-5 ton units (1-phas or high efficiency 3-phase) have multispeed, direct drive motors. All 6-8'/ton units (standard efficiency) shall have�belt drive motors with an adjustable idler-arm assembly for quick-adjustment to fan belts and motor sheaves. All motors shall be thermally protected. All 10 tons and 7%2-8'/2(high efficiency) have variable speed direct drive motors. All ind�oor fan motors meet the U.S. Energy Policy Act of 1992 (EPACT). Single Zone VAV-One Zone Variable Air Volume Mode Single zone VAV is designed for use in single zone applications like gymnasiums, auditoriums, manufacturing facilities, retail box stores, and any large open spaces, where therelis a lot of diversity in the load profile. Single Zone VAV(SZ VAV)is an ideal replacement to yesterdays constant volurrSe(CV)systems, by reducing operating costs while improving occupant comfort. SZ VAV systems combine Trane application, control and system integration knowledge to exactly match fan speed with cooling and heating loads, regardle�ss of the operating condition. Trane algorithms meet/exceed ASHRAE 90 1-2010, SZ VAV energy-saving recommend�tions, and those of CA Title 24 The result is an optimized balance between zone temperature control and system energy savings. Depending on your specific application, energy savings can be as much as 20+°/o Note: Building system modeling in energy simulation software li e TRACE is recommended to evaluate performance improvements for your application. SZ VAV is fully integrated into the ReliaTel Control systern and is available today. It provides the simplest and fastest commissioning in the industry through proven factory-installed, wired, and tested system controllers. All control modules, logic and sensors are factory installed, and test�d to assure the highest quality and most reliable system available.This means no special programming of algorithrns, or hunting at the jobsite for sensors, boards, etc.that need to be installed in the field Single zone VAV is a quick and simple solution for many applications and is available from your most trusted rooftop VAV system solution provid2r-Trane. Plenum Fan The following unit shall be equipped with a direct drive plenum fan design (all 10 tons and 7.5-8 5 ton high efficiency units) Plenum fan design shall include a backward-curved fan wheel along with an external rotor direct drive variable speed indoor motor All plenum fan designs will have a va�iable speed adjustment potentiometer located in the control box. Controls Unit shall be completely factory-wired with necessary con�rols and contactor pressure lugs or terminal block for power wiring. Unit shall provide an external location for mounting a fused disconnect device. A choice of microprocessor or electromechanical controls shall be available. Microproce sor controls provide for volt control functions. The resident control algorithms shall make all heating, cooling, and/or�entilating decisions in response to electronic signals from sensors measuring indoor and outdoor temperatures. The�control algorithm maintains accurate temperature control, minimizes drift from set point, and provides better building comfort.A centralized Microprocessor shall provide anti-short cycle timing and time delay between compressors to provide a higher level of machine protection.
