•Phase Monitors - Designed to prevent unit damage. The phase monitor will shut the unit down in an out-of phase condition. (Standard on units with Scroll Compressors.)

•Coil Guard - Customers can purchase a coil guard kit to protect the condenser coil from damage. Additionally, this kit stops animals and foreign objects from entering the space between the inner condenser coil and the main cabinet. This is not a hail guard kit.

•Dirty Filter Switch - This kit includes a differential pres- sure switch that energizes the fault light on the unit ther- mostat, indicating that there is an abnormally high pressure drop across the filters. Factory installed option or field installed accessory.

•Technicoat Condenser Coils - The condenser coils are coated with a phenolic coating for protection against cor- rosion due to harsh environments.

•Technicoat Evaporator Coil - The evaporator coils are coated with a phenolic coating for protection against cor- rosion due to harsh environments.

•BAS - Building Automation System Controls Simplic- ity™ INTELLI-Comfort™ Control - The York® Simplic- ity™ INTELLI-Comfort™ control is factory installed. It includes a supply air sensor, a return air sensor, and an outside air sensor. There are provisions for a field installed dirty filter indicator switch, an air-proving switch, an Outside Air Humidity sensor, a Return Air Humidity sensor, an Inside IAQ sensor, and an Outside Air IAQ sensor. Construction mode operation, 365-day real time clock with 7 day programming plus holiday scheduling is built-in. Two different modes of demand ventilation are achieved through the INTELLI-Comfort™ using CO2 sensors. It uses an inside CO2 sensor to perform Demand Ventilation. It can also use an Outside CO2 sen- sor to perform Differential Demand Ventilation. It uses a Patented Comfort Ventilation algorithm to provide com- fortable ventilation air temperature. The patented econo- mizer-loading algorithm will protect the equipment when harsh operating conditions exist. Humidity in the occu- pied space or return duct can be monitored and con- trolled via humidity sensors and the on-board connection for hot gas re-heat system. It uses the INTELLI-Start™ algorithm to maximize energy savings by recovering the building from the Unoccupied Setpoints to the Occupied Setpoints just in time for the Occupied Time Period to begin. The Simplicity™ INTELLI-Comfort™ balances space temperature, ventilation air temperature, CO2 and humidity for ultimate comfort.

FIELD INSTALLED ACCESSORIES

YORK® offers several equipment accessories for field instal- lation, for the Predator® line.

•Downflow Economizer - (With barometric relief) - The economizer is provided with a single enthalpy input. The economizer is 2% low leakage type. The economizer has spring return, fully modulating damper actuators and is capable of introducing up to 100% outdoor air. As the outdoor air intake dampers open, the return air dampers close. The changeover from mechanical refrigeration to economizer operation is regulated by the standard single enthalpy input. There is an optional input dual dry bulb available. To meet regulated air standards, the econo-

mizer control accepts an optional CO2 input for demand ventilation. With single enthalpy input, the economizer control monitors outdoor air. The dual enthalpy kit pro- vides a second input used to monitor the return air. With a dual input kit installed, the economizer control com- pares the values of the two enthalpy or temperature inputs and positions the dampers to provide the maxi- mum efficiency possible

•Horizontal Economizer - (Without barometric relief) - All features of the downflow economizer exist except you must order the duct mount barometric relief separately.

You must order a 1EH0408 if you are installing a power exhaust. You can order a 1RD0411 Barometric Relief for horizontal flow economizer.

•Slab Economizer for Energy Recovery Ventilator- (Without barometric relief or Fresh Air Hood) - The economizer is provided with a single enthalpy input. The economizer is 2% low leakage type. The economizer has spring return, fully modulating damper actuators and is capable of introducing up to 100% outdoor air. As the outdoor air intake dampers open, the return air dampers close. The changeover from mechanical refrigeration to economizer operation is regulated by the standard single enthalpy input. There is an optional input dual dry bulb available. To meet regulated air standards, the econo- mizer control accepts an optional CO2 input for demand

102, 90, DH 078 specifications

York DH series chillers, specifically models 078, 90, and 102, are recognized in the HVAC industry for their advanced features, efficiency, and reliability. These chillers are designed to provide exceptional cooling performance for commercial and industrial applications, prioritizing energy efficiency and sustainability.

One of the standout features of the York DH series is its dual-compressor system. This design not only enhances reliability but also contributes to energy savings by allowing the unit to operate at varying loads more effectively. This adaptability ensures that the chillers can maintain optimal performance even during fluctuating demand, reducing energy consumption and associated costs.

The DH series chillers employ a microchannel condenser technology that maximizes heat exchange efficiency. This technology reduces the amount of refrigerant required while also minimizing the footprint of the unit, offering significant advantages in space-constrained environments. Additionally, microchannel coils are less susceptible to corrosion, enhancing the longevity and reliability of the chillers.

Another notable feature is the use of variable-speed drives (VSD) in the compressor system. These drives allow for precise control of the compressor speed, enabling the chillers to adjust to the cooling demands dynamically. This flexibility not only enhances the overall efficiency of the system but also contributes to quieter operation, making the chillers suitable for environments where noise levels are a concern.

York's DH series also integrates advanced controls and monitoring capabilities. The intuitive control system allows for easy programming and operation, providing users with real-time data on system performance and diagnostics. This feature aids in maintenance and troubleshooting, reducing downtime and ensuring that the chillers operate at peak efficiency.

Safety is paramount in the design of the York DH chillers. Each model is equipped with multiple safety features, including pressure relief valves and temperature monitoring systems, to protect the unit during operation. This commitment to safety not only safeguards the equipment but also ensures compliance with industry standards.

In conclusion, the York DH 078, 90, and 102 chillers exemplify modern HVAC technology with their dual-compressor systems, microchannel condenser technology, variable-speed drives, and advanced control systems. These features combine to deliver efficient, reliable, and sustainable cooling solutions for a wide variety of applications. The York DH series represents a significant advancement in chiller design and functionality, making it a preferred choice for many professionals in the field.
