Field ConnectionsACUV-D series self-contained heavy duty air cooled condensing units are designed for minimum field interaction.

Power hook-ups for AHU starter and fan interlock and control wiring of room unit as per Electrical hook-up diagram is all that is required to electrically connect any model of ACUV-D series.

Every ACUV-D series condensing unit requires, at most, field installed fused disconnect switches or circuit breakers, and room unit.

Refer below for a schematic representation of required field electrical hook-ups for a standard ACUV-D series condensing unit.

All field wiring must be done in accordance with applicable local and national codes.

For maximum recommended fuse sizes and minimum circuit amps for cable sizing, see Page 19 - 23 of this bulletin.

The ACUV-D series is then ready to provide cooling, on demand.

Location and Space Requirements

Due to the vertical air flow discharge condenser design, it is recommended that certain precautions are to be taken before installation. There should be no obstruction on the air flow.

Orient the unit so that prevailing winds blow parallel to the unit length thus minimizing the effects on condensing pressure. If it is not practical to orient the unit in this manner, a wind deflecting shield should be considered.

It is also necessary to provide adequate clearance on all sides of the unit for service access and satisfactory performance. This will prevent excessive condensing temperatures and enhance system performance and operating economy.

A flat concrete foundation or floor which can support the weight of the equipment must be provided as the unit must be level for proper operation and functioning of controls.

Under certain critical conditions it is recommended that vibration isolators of rubber-in-shear or spring type be installed under the base.

The isolators must be designed for the operating weight of the unit. For operating load points refer to Loading Points Data (page 27 & 28).Correct selection of types of isolators depends upon application and structure.

Typical Refrigeration Piping

Legend

1. Expansion Valve.2. Sight Glass.3. Solenoid Valve.4. Filter Drier.5. Shut Off Valve.6. Liquid Line.7. Suction Line.

Single Circuit Unit Shown. For unit with multiple circuits, piping will be identical.

Refrigerant Piping

Correct design and size of refrigerant piping is necessary for proper operation. The refrigerant piping generally should be designed to accomplish the following:

a. To ensure proper refrigerant feed to the evaporator.

b. To provide practical refrigerant line sizes without excessive pressure drop.

c. To maintain uniform return of lubricating oil to the compressor.

d. To prevent liquid refrigerant from entering the compressor and causing compressor damage due to "slugging".

Field Expansion Valve Selection

The following recommendations should be taken into consideration when selecting expansion valves in field.

1. Expansion valves should be installed as close to the evaporator as possible, mounted directly to the distributor.

2. The following possible sources of pressure drop to be considered:

a. Friction losses through refrigerant lines.

b. Pressure drop across valves and controls.

c. Pressure drop due to vertical lift of liquid line for R-134a 1°F (0.55°C) sub cooling must be allowed for each 5.5 ft (1.7m) vertical rise in order to avoid flash gas forming due to the weight of the column of liquid refrigerant.

SKM ACUV-D Series units are designed with a sub cooling circuit enough to sub cool the liquid 12°F (6.6 °C), which gives the liquid maximum 66 ft. (20m) lift without additional sub cooling. Liquid suction heat exchanger can be used for additional sub cooling in order to avoid flash gas forming.

Matching DX Coil Selection

For single circuit ACUV-D Series, the DX coil selection in a MAH or other air handler from SKM should be based on total capacity. For multiple circuit ACUV-D Series, extra care should be exercised and correspondingly split, by face area or number of rows to correspond and match the capacity split available in the multiple circuited ACUV-D Series selected. For optimum matching the DX coil should be ordered from SKM as well.

SKM provides correct no. of feeds and circuits and properly sized distribution to ensure the correct split on the DX coil is made available to match the particular selected ACUV-D Series model.
