Page 9: Reheat Capacity
OVERVIEW Packaged Refrigeration for DN-Series DOAS 1.4 REHEAT CAPACITY Each DOAS model has multiple reheat capacities that can be specified. Reheat capacity is determined by matching the expected operating conditions of the unit to the customer’s desired leaving air temperature of the Supply Air. 1.5 EVAPORATOR COIL OPERATION Liquid refrigerant enters the evaporator coil at the Evaporator Temperature (~40°F) and at a low pressure (~119 psig). -
Page 10: User Interface
OVERVIEW DOAS Packaged Refrigeration for DN-Series 1.8 USER INTERFACE The user interface for the refrigeration system is the keypads and data screens found on the faces of both the primary DOAS Controller and the secondary refrigeration controller. The two controllers are connected by a serial cable. The DOAS controller requires various configuration settings to operate (at the primary user interface), and will then provide a Call for Cooling signal to the secondary refrigeration controller. -
Page 11: Component Descriptions
COMPONENT DESCRIPTION Packaged Refrigeration for DN-Series DOAS 2.0 COMPONENT DESCRIPTIONS 2.1 CABINET The DN DOAS with Packaged Refrigeration varies from the standard DOAS unit. Access panels are added to the back of the cabinet and the metal panel that separates the EA fan compartment from the controls compartment includes a removable access panel, for servicing the compressor compartment. -
Page 12: Refrigerant
COMPONENT DESCRIPTION DOAS Packaged Refrigeration for DN-Series 2.2 REFRIGERANT The refrigerant used in all Packaged Refrigeration systems is R-410A. There are minimal hazards involved in its use. It is a non-flammable, colorless, volatile liquid with a faint sweetish odor. It may also be odorless. There are two primary hazards involved in its use: since it will displace air, it could cause a reduction in available oxygen levels, causing dizziness. -
Page 13: Condenser Fans
