AMAC units are high thermodynamic engineering products, studied with high accuracy in balancing compressors, condensers and evaporators in order to offer high performances and wide safety margins. The choose of the materials and the equipment adopted for the products has been made without any compromises, taking care of quality and long life purposes. The products meet ISO 9001 requirements, an assurance beyond any doubts of the high producing standards followed by ACSON. Working Reliability In summer mode (the mode is simply selected by means of a switch) the unit produces chilled water through a plate exchanger while the condenser coils dissipate the heat rejection. In winter mode plate heat exchanger works as a water condenser to produce hot water while condenser coils dissipate cooling capacity to the ambient air. The periodic defreezing, necessary during low temperature functioning of the unit is run by the system by means of automatic switching of the 4-ways inversion cycle valve. Modular Design AMAC170A(R) and AMAC210A(R) are designed as the 2 original modules, different numbers of modules can be combined to satisfy different load. The largest combination is 8 modules, it convenient to transportation and installation. Highly Flexible Design The AMAC units are available in sizes covering a range from 50 to 420 kW nominal cooling capacity and with availability of many accessories, and the applications of high tech control and safety devices, give to these products high flexibility for their installation in commercial, residential and industrial environments. It couples with different type of fan coil or AHU, and satisfies different area by modular combination. Low Installation Costs The complete assembly of the units and function testing at the factory reduces the cost of installation on site. A rigid steel base distributes the weight of the unit to the support points and allows simple installation by an easy access to the lifting points. Factory Testing Each unit is pressure tested, vacuum tested, evacuated and charged with refrigerant requested. It is then tested at the factory’s test bench under the design conditions specified by the customer. Upon request, a second series of tests can be carried out witnessed by the customer. Before shipment, each unit is re-checked for pressure and refrigerant charge control.

The compressor adopts hermetic type to further eliminate operating noise and vibration. Air-cooled Condenser The two air cooled condenser coils with V-shaped is consist of staggered rows of 3/8" OD seamless copper tube, mechanically expanded onto die formed aluminum fins to ensure optimum heat exchange capability. Condenser Fan Motor To achieve the high air charge requirement, the unit is equipped with the high airflow propeller fan which is made of acryl styrene resin. The fan is direct driven by weatherproof single-phase motor to ensure reliable continuous operation. Evaporator The heat exchanger is made of stainless steel plates closely arranged and brazed together to ensure high heat exchange efficiency. The complete heat exchanger is insulated with thermal closed cell nitric rubber foam to give optimum thermal insulation. Refrigerant Circuit The refrigerant circuit is factory brazed and evacuated before accurately charged with R22 to ensure optimum operating requirement. To ensure flawless continuous operation, each refrigerant circuit is equipped with a carefully sized thermostatic expansion valve. Additional Safety Protection The modular air-cooled chillers are equipped with intelligently designed safety control to ensure continuous safe operation. High and low pressure switch is provided in cooling models to prevent the compressor damage resulting from both abnormally high discharge head pressure and low pressure due to insufficient gas. The heat pump models are provided with a high-pressure switch. Flow switch is provided in the unit to protect against damage to the water pump. The standard mechanical controller provides accurate water temperature control in the circuit by closely monitoring and reacting to the input from the water entering temperature, water leaving temperature and ambient air temperature.

1. Inspection • All modular air-cooled chillers are transported with pallet. Each unit has been filled with refrigerant. It is not

necessary to fill it again. • As soon as the unit is received, it should be inspected for any damage that may have occurred in transit. And all the

separated parts are received. 2. Storage of the Unit • If the chillers are not installed for the moment, it is strictly prohibit stacking them. 3. Location of the Unit • Don’t install the unit in airshaft, courtyard, or other places which is limited for the unit. Or it will maximize the vibration

and noise because of the echo and resonance of the wall or other obstacles. • Space for access to front and sides of the equipment must be provided to accommodate such maintenance and

service and to permit unobstructed flow of air to and from the unit. • Install the modular air-cooled chillers in a way such that hot air distributed by the condensing unit cannot be drawn in

again (as in the case of short circuit of hot discharge air). Allow sufficient space for maintenance around the unit. • Ensure that there is no obstruction of airflow into or out of the unit. Remove obstacles that block air intake or

discharge. • 3.5 The location must be well ventilated, so that the unit can draw in and distribute plenty of air thus lowering the

condensing temperature.

• The location must not be susceptible to dust or oil mist to avoid condenser coil being choke by the contaminant. As the general safety precaution, it is advised that no flammable danger gas should be located near to the chiller.

4. Handling • Each modular air-cooled chiller is skidded at the factory. Care should be taken during handing to avoid damage to

the unit and internal components. Fork lifter or cable crane should be used for easy to schlep. 5. Lifting Method • When the modular air-cooled chillers are to be lifted and moved attached ropes to the suspension plates provided on

the top of the unit. • When it is lifted, hook should be as directly aligned over the center of gravity as possible. • Care should be taken to avoid contact with the main unit while carrying. • It is necessary to protect the chiller with the blanket or pallet so that the ropes should not injure the unit.

6. Installation Base • The unit must be installed on a flat and level concrete foundation. It can be conveniently installed on rooftop, terrace

and other proper places. • Drain pipe • Strong enough

Note:

Both system 1 and system 2 are used on less than 6unit connection (Inc. 6 units). System 2 is most used on more than 6 unit connection. This is helpful for balance of the hydraulic system.

Prior to starting up the unit, flushing of the water system is required:

1. Shut off the inlet and outlet valves and turn on the bypass valve. 2. Run the pump to circulate the water in the system for a while. 3. Open up the strainer to inspect the filter. 4. Clean the filter if necessary to ensure no debris trap in the piping system. 5. Shut off the bypass valve and turn on the inlet and outlet valves 6. System is ready for operation.

Be sure to use clean water when filling in the water circuit to avoid heavy corrosion and choking of the system.

If the chiller is operated under very oily, salty or acidic atmosphere or water, these substances may lead to capacity drop or failure of the unit.
