UNIT CABINET

1.Unit cabinet shall be constructed of G90 galvanized steel, with exterior surfaces coated with a non-chalking, powered paint finish, certified at 750 hours salt spray test per ASTM-B117 standards.

2.Indoor blower section shall be insulated with up to 1” thick insulation, coated on the air side. Aluminum foil faced insulation shall be used in the furnace compart- ment and be fastened with ridged fasteners to prevent insulation from entering the air stream.

3.Cabinet panels shall be large size, easily removable for servicing and maintenance.

4.Full perimeter base rails shall be provided to assure reli- able transit of equipment, overhead rigging, fork truck access and proper sealing on roof curb applications.

5.Disposable 1" filters shall be furnished and be accessible through a removable access door, sealed air tight. Units filter track shall be designed to accommodate either 1 or 2" filters.

6.Fan performance measuring ports shall be provided on the outside of the cabinet to allow accurate air measure- ments of evaporator fan performance without removing panels or creating air by-pass of the coils.

7.Units vertical discharge and return duct configuration shall be designed to fit between standard 24" O.C. beams without modification to building structure, duct work and base unit.

036-21411-002-A-0204

8.Condensate pan shall be internally sloped and conform to ASHARE 62-89 self-draining standards. Condensate connection shall be a minimum of 3/4" I.D. female and be a ridged mount connection.

INDOOR (EVAPORATOR) FAN ASSEMBLY

1.Fan shall be direct drive, multi-speed, or a factory installed belt drive, adjustable-pitch motor pulley option. Job site selected (B.H.P.) brake horse power shall not exceed the motors nameplate horse power rating, plus the service factor. Units shall be designed not to operate above service factor.

2.Fan wheel shall be double-inlet type with forward-curved blades, dynamically balanced to operate smoothly throughout the entire range of operation. Airflow design shall be constant air volume.

3.Bearings shall be sealed and permanently lubricated for longer life and no maintenance.

OUTDOOR (CONDENSER) FAN ASSEMBLY

1.The outdoor fan shall be of the direct-driven propeller type, discharge air vertically, have aluminum blades riv- eted to corrosion resistant steel spider bracket and shall be dynamically balanced for smooth operation.

2.The outdoor fan motor shall be totally enclosed with per- manently lubricated bearings and internally protected against overload conditions.

REFRIGERANT COMPONENTS

1.Compressors:

a.Shall be fully hermetic type, direct drive, internally protected with internal high-pressure relief and over temperature protection. The hermetic motor shall be suction gas cooled and have a voltage range of + or - 10% of the unit nameplate voltage.

b.Shall have internal spring isolation and sound muf- fling to minimize vibration and noise, and be exter- nally isolated on a dedicated, independent mounting.

2.Coils:

a.Evaporator and condenser coils shall have alumi- num plate fins mechanically bonded to seamless internally-enhanced copper tubes with all joints brazed. Special Phenolic coating shall be available as a factory option.

b.Evaporator and Condenser coils shall be of the direct expansion, draw-through design.

3.Refrigerant Circuit and Refrigerant Safety Components shall include:

York D1EE036, D1EG warranty Mechanical Specifications

D1EG, D1EE036 specifications

The York D1EE036 and D1EG are two models of high-performance direct expansion (DX) rooftop air conditioning units designed for commercial applications. These units are known for their efficiency, reliability, and advanced technology.

The D1EE036 model is particularly recognized for its energy efficiency, featuring a high-efficiency scroll compressor. This compressor operates at lower energy consumption levels while providing consistent cooling performance. The unit is equipped with variable speed technology, which adjusts the compressor's speed according to the cooling demand. This feature not only optimizes energy use but also minimizes the sound levels during operation, making it suitable for noise-sensitive environments such as hospitals and schools.

On the other hand, the D1EG model is designed for versatility and offers a range of custom configuration options. It incorporates advanced controls that allow for integration with building management systems, enabling users to monitor and manage their HVAC systems remotely. The D1EG is also notable for its robust construction, with weather-resistant enclosures that ensure durability and longevity in various environmental conditions.

Both models feature an advanced microprocessor control system that provides precise temperature control and enhances overall system efficiency. These controls allow for multiple unit configurations, including staged cooling, which further contributes to energy savings. Additionally, both units come equipped with high-efficiency filters that improve indoor air quality by trapping dust, pollen, and other airborne particles.

From a technological standpoint, the York D1EE036 and D1EG models support environmentally friendly refrigerants, which comply with the latest regulations for reducing ozone depletion potential. The use of these refrigerants not only helps in meeting regulatory requirements but also aligns with global sustainability goals.

In summary, the York D1EE036 and D1EG rooftop units are engineered to deliver excellent performance, adaptability, and energy efficiency for commercial settings. Their combination of innovative technologies, environmentally conscious design, and advanced control features make them a compelling choice for businesses looking to enhance their HVAC systems while reducing operational costs. Whether requiring quiet operation or robust configurability, these units offer solutions that cater to diverse commercial needs.
