2 YORK YPRE RTR/RTP SERIES Air to air packaged rooftop units Cooling only and heat pump versions Refrigerant R407C Extreme flexibility Cooling range from 110 to 406 kw Johnson Controls recognizes that large, single packaged units can have a significant impact on a building s energy bill. For that reason, YORK YPRE units have been designed to address the economic concerns of facility owners and designers. High-efficiency scroll compressors, multiple-step capacity control, and fully modulating gas heat deliver superior energy performance and better comfort. The microprocessor control ensures the proper quantity of ventilation air, eliminating the cost of conditioning excess air. An airside economizer enables compressorfree cooling when outdoor air is cool and dry, and Variable Speed drives significantly reduce the power consumption of the drive motors. An option for cross flow plate heat exchangers gives added heat recovery and can reduce energy costs even further. Application Flexibility Flexible design configurations simplify the design process,making YORK YPRE units applicable for virtually any building application: commercial buildings, schools, hospitals, and more. Airflow configurations support variable air volume (VAV), changeover/bypass, and constant-volume applications. Supply-duct connections are configurable in multiple orientations. In addition to cooling-only models, available heating configurations include staged gas, modulating gas, electric resistance and hot water. by johnson controls

The coil is fed by external hot water through a suitable 3-way mixing valve, controlled by the microprocessor. BG HOT GAS POST-HEATING COIL Coil with copper pipes, aluminium fins and copper manifolds; this coil is used to re-adjust the air temperature to the requested value, when the evaporator is used to reduce the supply air relative humidity. The coil is supplied by the hot gas coming out from the compressor, through a solenoid valve controlled by the microprocessor, therefore there is no need for external heating sources. BT REGULATION OF CONDENSING PRESSURE device for the regulation of the condensing pressure, through the control of the fans speed rotation. In case of cooling operation, the phase regulation electronic equipment reduces the external fans speed rotation when the condensing pressure decreases, so as to allow suitable working conditions. Also suitable for use for low external air temperatures. F FREE-COOLING OPERATION On the base of the comparison between the internal and the external temperature, the microprocessor controls the motorized dampers, to use, in the best way, the energy in the external air so to satisfy the heating loads. In this way, the working time of the compressors and of the external fans is remarkably reduced and, as a consequence, also the electrical consumption. On demand, it is possible to use enthalpic control of free-cooling, so to use the external air for controlling the internal relative humidity, when possible. Where the unit is also equipped with heat recovery, the standard version will be provided with 3 dampers. On demand, it is possible to supply a 5 damper version. FT BAG FILTERS Rigid bag filters with filtering efficiency F7 (in conformity with EN779:2002), complete with G4 prefilters (in conformity with EN779:2002).
