GENERAL MECHANICAL SPECIFICATIONS

GENERAL - All 2 to 10 ton models ship with a full refrigerant charge. The 12 and 15 ton models are shipped as separate evaporator and condensing unit modules (nitrogen holding charge only). The 4 through 10 ton units include refrigeration line shut-off valves to allow the units to be field split. All pack- ages/models are designed for suspended mounting via inte- gral structural channels.

CABINET - All cabinets are completely constructed of 18 Gauge corrosion resistant "Galvalume" coated steel. The entire unit interior (both evaporator and condensing section) is insulated with 1/2" thick 2 LB density insulation. Service panels are equipped with 1/2" thick 2 lb. density insulation. Service panels are equipped with lifting handles for ease of removal and handling.

COMPRESSORS - All models utilize "Scroll" type hermetic compressors. Compressors are mounted on rubber isolators to minimize vibration transmission. Internal overload protec- tion is provided. External high pressure and low pressure cut- out switches are included in each compressor control circuit. Crankcase heaters are standard on all models.

REFRIGERANT CIRCUIT - The 2 to 5 tons units use a single refrigeration circuit. The 8 to 15 ton units feature two indepen- dent refrigeration circuits. Each circuit includes an adjustable thermal expansion valve (with external equalizer), liquid line filter drier, sight glass/moisture indicator, and service gauge ports.

EVAPORATOR AND CONDENSER COILS - The evaporator and condenser coils are constructed of internally enhanced

copper tubes mechanically bonded to rippled aluminum plate fins. Both coils are employed in a draw-through configuration. Large evaporator coil face area minimizes potential water blow-off (max face velocity is 550 fpm at rated airflow).

INDOOR/OUTDOOR FANS - Forward curved, double inlet and double width centrifugal blowers are used for both evap- orator and condenser air movement. blow wheels are fabri- cated of galvanized steel. Blowers employ solid steel shafts, supported in permanently lubricated ball bearing. All blow- ers are belt driven in permanently lubricated ball bearing. All blowers are belt driven. Variable-pitch motor sheaves allow for field adjustment of blower rpm.

ELECTRICAL/CONTROLS - All units are completely factory wired with all necessary controls. Manual reset protection is provided on both evaporator and condenser motors. A man- ual reset circuit is also provided on each compressor control circuit in the event of high/low pressure cutout. A 24 volt con- trol circuit with oversize transformer, is provided for field con- nection.

FILTERS - All models are shipped with 2 inch thick medium- efficiency throwaway filters factory installed. Filter rack is internal to the cabinet.

FACTORY INSTALLED ACCESSORIES

OVERSIZED EVAPORATOR FAN MOTORS - Increased horsepower motors and drive components are available for those applications where external static pressure require- ments exceed the capability of the standard motor.

D3HH 180, D3HH 024 specifications

The York D3HH 024 and D3HH 180 are two prominent models in the York range of commercial heating, ventilation, and air conditioning (HVAC) systems. These units are designed for high efficiency and reliability, catering to various applications in commercial and industrial settings. The D3HH series showcases innovative technologies that enhance performance while reducing energy consumption.

The D3HH 024 model is a compact and efficient unit featuring a cooling capacity of 24,000 BTU/h. This makes it ideal for smaller commercial spaces or where precise climate control is essential. Its modular design allows for easy installation and maintenance, ensuring minimal disruption to operations. The D3HH 024 incorporates advanced inverter technology, which provides variable speed compressor operation. This technology not only enhances comfort by maintaining consistent temperatures but also significantly reduces energy costs by operating only at the required capacity.

On the other hand, the D3HH 180 model offers a higher cooling capacity of 180,000 BTU/h, making it suitable for larger commercial applications. This model is built with durability in mind, utilizing high-quality materials that withstand harsh environmental conditions. The D3HH 180 also features a robust heat exchanger, optimizing thermal efficiency and enhancing the unit's overall performance.

Both models are equipped with smart controls, allowing for remote management and monitoring. These controls facilitate energy management strategies and help in integrating the systems with building management systems (BMS), demonstrating York's commitment to smart technology. Additionally, both units adhere to eco-friendly refrigerant standards, ensuring compliance with environmental regulations.

Another notable feature of the D3HH series is its whisper-quiet operation. Enhanced sound-dampening technology minimizes noise levels, making these units ideal for applications where noise is a concern, such as office spaces or educational institutions.

In summary, the York D3HH 024 and D3HH 180 models stand out in the commercial HVAC market for their efficiency, advanced technologies, and user-friendly features. Whether it's the compact design of the D3HH 024 or the robust capabilities of the D3HH 180, both units provide effective solutions for diverse heating and cooling needs while prioritizing energy efficiency and environmental responsibility. These models are an excellent choice for any business looking to optimize their climate control systems.
