IntroductionThe new series of SKM air cooled split system air conditioner has been developed to satisfy the needs in air conditioning practices, meet high quality of job requirements every time and to deliver the best in split system performance.SKM air cooled split air conditioners consist of ceiling suspended indoor air handler (CADX-L) matched with floor mounted outdoor air cooled condensing unit (ACUM-L) series.

SKM air cooled split air conditioners available in 11 variations to cover the range from 5 TR to 25 TR (18 kW to 88 kW) in 60Hz at nominal AHRI conditions. It is suitable to operate in a wide range of ambient temperatures from 50 °F (10°C) to 125°F (51.7°C).

SKM split units are internally wired and all that is required to be done on site is ducting, refrigerant piping, power wiring for CADX-L motor from ACUM-L, thermostat wiring and power supply connection which reduces installation work and consequently keeps costs to a minimum. Two independent refrigeration circuits are provided when two compressors are used.

SKM provides qualified service and stock of replacement parts in all major cities of the G.C.C. countries, Egypt, Jordan, and Pakistan. See back cover for details or call SKM.

Condenser Coils

Condenser coils are manufactured from cross fin Waffle Louvre and Hi-X seamless copper tubes mechanically bonded to aluminium fins to ensure optimum heat transfer. All coils are tested against leakage by air pressure 450psig (3100 kPa) under water. An integral subcooling circuit is incorporated in the lower section of the condenser to increase system capacity. The additional condenser surface provides more cooling using less energy at no additional cost.

Condenser Fans

Condenser fans are propeller type with aluminium alloy blades and are directly driven by electric motors. Motors are Totally Enclosed Air Over (TEAO), six pole or four pole with Class F insulation and minimum IP-54 protection. The TEAO and Class F insulation features ensure long life and are unique to SKM. The condenser fans are individually statically and dynamically balanced at the factory. Complete fan assembly is mounted downward on the strong and acrylic coated fan guard for the smaller units. For larger units fan, assembly is separate and provided with suitable acrylic coated fan guard.

GENERAL FEATURESSKM split system air conditioners incorporate many features and benefits in both the air handler and condensing units, which together provides a heavy duty, robust and long lasting commercial unit’s application.SKM split air conditioners combined high efficiency components to provide an extremely rugged and energy efficient split system that will provide cooling with higher efficiency for a long and extended period of time. SKM split system is ACUM-L+ CADX-L is yet another model in the top class range of SKM products which uses the following basic components:

• High efficiency totally sealed hermetic scroll compressors utilizing the most current state of the art technology and provides smooth, efficient and quiet operation.

• Totally enclosed, Class F insulated,condenser and evaporator fan motors.

• Heavy duty condenser and evaporator coils optimized and designed for a long life maintenance free operation.

• Cabinet construction specifically for gulf climate condition.

• Electronic control board for the unit operation.

• Factory matched performance and reliable output to minimize field decisions.

• Many standard features which are not included in residential domestic type split systems.

• Typically, much heavier gauge tubing and thicker fins for ruggedness and long life.

Compressor

Compressors used in the ACUM-L series condensing units are hermetically sealed, hi-efficiency, low noise, and compact scroll with the following features:

• High efficiency.• Quiet operation, low sound levels.• Better debris handling.• Self compensating of wear (“wear-in vs. wear-out”).• 70% fewer moving parts than comparably sized reciprocating

• Internal motor protection / Advanced scroll temperature

• Suction gas motor cooling.• Suction screen.

COMPONENT FEATURES

• Disc type check valve.• Centrifugal force for oil lubrication.• Brazed fittings as standard, rotalock as an option.

Notes : 1. Pipe diameters are based on equivalent length of copper tubing sizes. 2. Pipe sizes are based on 2ºF (1.1ºC) or less temperature losses for liquid and suction line in equivalent pipe length. 3. If the condensing unit is below the evaporating unit, the maximum lift should not exceed to 66 feet. 4. Do not exceed 100 feet piping length without checking with SKM. 5. These sizes are for guidance only. For detailed proper piping, refer to recognized piping references like ASHRAE Guide and Data Book.

The recommended or required suction and liquid line sizes do not necessarily correspond with the refrigerant connections available on the outdoor or indoor unit. Necessary transformation may be required and it’s field performed.

Installation and Commissioning• Install the unit in such a location which is flat and strong enough to support its weight.

• All field wiring must comply with applicable local and national codes.

• Service spacing should be provided as shown in the figure. If any obstacles are around the unit, distributed air is short-circuited so that the unit stops frequently and access to the unit is difficult for inspection and aftersales services.

Typical Refrigeration Piping

Correct design and size of refrigerant piping is necessary to 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 refrigerant from entering the compressor and causing compressor damage due to “slugging”.
