Each refrigeration system includes:

 

•

Thermal expansion valve with equalizer

 

•

High and low pressure switches

 

•

Sight glass with moisture indicator

 

•

Filter drier

 

•

Liquid line solenoid valve

Cooling coil

The AFX utilizes dual distributors on one circuit of the refrigeration system.

 

During dehumidification the smaller distributor is turned off effectively

 

reducing the active circuits of the evaporator coil. During this mode of

 

operation the evaporating temperature is decreased, resulting in a lower coil

 

surface temperature. This reduction of the coil temperature decreases the

 

sensible heat ratio of the coil allowing a greater percentage of moisture

 

removal. Additionally the warmer air leaving the inactive circuits of the

 

evaporator coil blends with the near saturated air from the active circuits

 

raising the dry bulb temperature of the blended air well above saturation.

Condenser

Water-and glycol-cooled systems employ a brazed plate condenser that uses

 

the latest heat transfer technology. Type 316L stainless plates are brazed

 

together in a vacuum furnace and comply with ASME pressure vessel code.

 

Pressure rating is 450 psi (3100 kPa).

Air filter

The filtration of conditioned air is extremely vital to maintaining the clean,

 

particle-free environment required by electrical equipment. The AFX Series

 

uses 30% efficient (ASHRAE 52.1–92), 4" (102 mm) deep filters, with full

 

depth filter pleats. In addition to high filtration properties, these filters

 

produce a lower pressure drop than standard filters so less energy is required

 

during normal operation. Filters are easily replaced from the top on

 

downflow units and from the front on upflow units.

Water-regulating

The water-and glycol-cooled systems maintain proper performance by

valves

sensing refrigerant discharge pressure and regulating the amount of water or

 

glycol supplied to the condenser. Two-way and three-way valves are

 

available. The standard valve pressure rating is 150 psi (1030 kPa).

Airflow sensor

The air proving switch is continuously monitored by the microprocessor.

 

Upon detection of a loss of air flow the microprocessor will deactivate:

 

cooling, heating, humidification and dehumidification. After the air flow has

 

been restored for a predetermined period of time the microprocessor will

 

reactivate the functions as needed.

Clogged filter alarm

An adjustable air pressure differently switch senses the pressure drop across

 

the filters. Upon sensing an excessive pressure drop, the switch activates the

 

alarm circuit of the microprocessor and displays a clogged filter message

 

simultaneously with an audible signal.
