FEATURES AND BENEFITS

BLOWER

A wide selection of supply air blower options are available to meet a variety of airflow requirements

Blower Motor

• Ball bearings

Supply Air Blower

• Forward curved blades

• Double inlet

• Blower wheel statically and dynamically balanced

• Ball bearings

• Adjustable pulley (allows speed change)

• Blower assembly slides out of unit for servicing

Single Zone VAV Supply Fan Operation

• Single Zone VAV stages the amount of airflow according to compressor stages, heating demand and ventilation demand

• Units utilize a Variable Frequency Drive (VFD) to stage the supply air blower airflow

• VFD alters the frequency and voltage of the power supply to the blower to control blower speed

• The supply air blower has two speeds:

1. Low speed for part-load cooling operation.

Note - Low speed is 60% of high speed.

2. High speed for full load cooling and all heat modes.

• Full speed blower operation is set by adjusting the motor pulley to deliver the desired air volume

• Ventilation speed is selectable between high and low speed NOTE - Part load airflow in cooling mode should not be set below 220 cfm/nominal full load ton to reduce the risk of evaporator coil freeze-up.

• VFD has an operational range of -40 to 125° F outdoor air ambient temperature

NOTE - Lower operating costs are obtained when the blower is operated on lower speeds.

HH

K-Series™ Packaged Electric / Electric 15 to 25 Ton / Page 6

BLOWER (continued)

Single Zone VAV Air Volume Sequence of Operation

• Ventilation speed is determined by the VENT SPEED switch setting on VFD control board (LO or HI)

• Blower operates in low speed for mechanical cooling

(Y1)

• Blower operates in high speed for any other mode (free cooling, mechanical cooling Y1+Y2, and heating)

• Economizer damper minimum position is fully closed in unoccupied mode

• In occupied mode, the economizer damper minimum position is determined by the setting of the two potentiometers on VFD control board:

• LO SPD MIN POS potentiometer sets the minimum position when blower is operating at low speed

• HI SPD MIN POS potentiometer sets the minimum position when blower is operating at high speed

Ordering Information

• Specify blower motor, motor horsepower and drive kit number when base unit is ordered NOTE - Units equipped a Variable Frequency Drive (VFD) are designed to operate on balanced, three-phase power. Operating units on unbalanced three-phase power will reduce the reliability of all electrical components in the unit. Unbalanced power is a result of the power delivery system supplied by the local utility company. Factory-installed inverters are sized to drive blower motors with an equivalent current rating using balanced three-phase power. If unbalanced three-phase power is supplied; the installer must replace the existing factory-installed inverter with an inverter that has a higher current rating to allow for the imbalance.

Refer to the installation instructions for additional information and replacement information.

OVERVIEW

NOTE - Not available with Eco-Last™ Coil System (180, 210 and 240 models only).

Conventional Fin/Tube condenser coil must be ordered as a factory option.

• Factory installed option designed to control humidity

• Provides dehumidification on demand using ASHRAE

90.1 recommended method for comfort conditioning humidity control

• Unit comes equipped with one row reheat coil, solenoid valve and humidity controller

• A thermostat with a dehumidification output, a dehumidistat, or a DDC controller with an isolated output is required to control humidity and must be located in the occupied space

BENEFITS

• Improves indoor air quality

• Helps prevent damage due to high humidity levels

• Improves comfort levels by reducing space humidity levels

OPERATION

No Dehumidification Demand

• The unit will operate conventionally whenever there is a demand for cooling or heating and no dehumidification demand

• Free cooling is only permitted when there is no demand for dehumidification

Dehumidification Demand Only

• Dehumidification is initiated by an output from a dehumidistat (furnished), an optional thermostat with a dehumidification output or an optional DDC controller with an isolated output to control humidity

• Reheat operation will initiate on a dehumidification demand and does not require a cooling demand

• The unit will operate in the dehumidification mode until the relative humidity of the conditioned space is below the setpoint

• This reduces sensible cooling capacity and extends compressor run time to control humidity when the cooling load is low

• A solenoid valve diverts hot gas from the compressor to the reheat coil

• The cooled and dehumidified air from the evaporator is reheated as it passes through the reheat coil

• The de-superheated and partially condensed refrigerant continues to the outdoor condenser coil where condensing is completed

• The unit will continue to operate in this mode until the dehumidification demand is satisfied
