2. FEATURES

REFRIGERANT CIRCUIT

Models AMAC/A4AC80~150C/CR has been designed with two separate refrigerant circuits, i.e. it has two compressors. By doing so, the unit has part loading capabilities, i.e. 0-50-100% of rated capacity. This will improve the reliability and energy efficiency of the unit, especially during low loading operations. Each circuit is factory brazed and evacuated before accurately charged with refrigerant to ensure optimum performance. Because each circuit is separated, there is no danger of cross-contamination should either one of the compressor experiences a burnt-up. Each circuit is also equipped with a carefully sized thermostatic expansion valve (for cooling only units) to give optimum performance characteristic. For the heatpump version, the expansion process is done with capillary tubes.

SCROLL COMPRESSOR

Scroll Compressors are used (for model which is available) for the units (AMAC/A4AC20C/CR using rotary

compressor) to give quiet and reliable performance over a wide operating temperature range. However, in order to protect the compressors from damage, a phase protector (for model which is available) is provided to prevent the compressors from rotating in the wrong directions.

TANDEM COMPRESSOR

A5AC models are using R410A rotary compressors in tandem configuration. Tandem compressors are highly efficient and cost saving. It reduces mechanical losses, minimize gas flow losses and turbulence. There are 3 steps capacity loading (0-40-60-100%) for A5AC40/50CR and 2 steps capacity loading (0-50-100%) for A5AC30/ 55CR.

CONDENSER FAN MOTOR

Models AMAC/A4AC80~150C/CR is equipped with two high air flow propeller fan blades which are made of

metal. The fans are driven vertically by weather proof motors which are single phase type.

EVAPORATOR

The heat exchanger is made of stainless steel plates closely arranged and brazed together (BPHE) to ensure high heat exchange efficiency. For models AMAC/A4AC80~150C/CR, the water flow through the BPHE in a channel on its own, while because of the two compressors, the refrigerant flows through another two separate channels. The refrigeran t will either be in a counter-flow or parallel-flow with respect to the water, depending on the mode of operation (cooling or heating).

SAFETY PROCETECTION

The safety protections provided for the mini chiller are:

a) High and low pressure switches b) Differential water flow switch c) Compressor, water pump and fan motor overload protectors d) Anti-freeze protection sensor

During abnormal condition, chiller panel controller will turn off the unit and then display the faults of operation.

WATER TANK AND PIPING CONNECTION

The models A4AC/AMAC80~150C/CR does not come with a water buffer tank. However, the unit does come with an 8 liters expansion tank. Besides that, an optional 135L hydraulic tank is also available.

The external water piping connection can be made either from the left or right side of the unit. Connection is done with Ø1-1/4 “ female thread couplings for both supply and return pipes.

Meanwhile, AMAC/A4AC20~60C/CR does come with a 22 L or 40 L (refer to specification) water buffer tank.

Page 8

ANTIFREEZE PROTECTION

The chiller unit has several anti-freeze protection features:

1. Brazed plate heat exchanger anti-freeze

The BPHE has a strip heater around it to prevent water freezing inside

2. Auto mode

The chiller controller will force on the unit to the heat mode if the outdoor ambient air temperature becomes too cold.

MAINTENANCE

In order to facilitate of the controller, a rocker switch is provided to power-off the supply to the PCB. However, switching off the switch will not disconnect the main incoming power supply to the chiller unit.

PRECAUTIONS AND INSTALLATION

SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R407C UNIT

1) WHAT IS NEW REFRIGERANT R407C?

R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor’s lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.

2) COMPONENTS

Mixture weight compositionR32(23%), R125(25%), R134a(52%)

3) CHARACTERISTIC

• R407C liquid and vapor components have different compositions when the fluid evaporates or condenses. Hence, when leak occurs and only vapor leaks out, the composition of the refrigerant mixture left in the system will change and subsequently affect the system performance. DO NOT add new refrigerant to leaked system. It is recommended that the system should be evacuated thoroughly before recharging with R407C.

• When refrigerant R407C is used, the composition will differ depending on whether it is in gaseous or liquid phase. Hence when charging R407C, ensure that only liquid is being withdrawn from the cylinder or can. This is to make certain that only original composition of R407C is being charged into the system.

• POE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for R22 compressor. Extra precaution must be taken not to expose the R407C system too long to moist air.

4) CHECK LIST BEFORE INSTALLATION/SERVICING

• Tubing Refrigerant R407C is more easily affected by dust of moisture compared with R22, make sure to temporarily cover the ends of the tubing prior to installation

• Compressor oil No additional charge of compressor oil is permitted.

• Refrigerant No other refrigerant other that R407C

• Tools Tools specifically for R407C only (must not be used for R22 or other refrigerant)

i) Manifold gauge and charging hose ii) Gas leak detector iii) Refrigerant cylinder/charging cylinder iv) Vacuum pump c/w adapter

v) Flare tools vi) Refrigerant recovery machine

5) HANDLING AND INSTALLATION GUIDELINES

Like R22 system, the handling and installation of R407C system are closely similar. All precautionary measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and thorough leak check and vacuuming are equally important requirements. However, due to zeotropic nature of R407C and its hydroscopic POE oil, additional precautions must be taken to ensure optimum and trouble free system operation.

a) Filter dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise the

contamination of moisture and dirt in the refrigerant system. Filter dryer must be of molecular sieve type. For a heat pump system, install a two--way flow filter dryer along the liquid line.

b) During installation or servicing, avoid prolong exposure of the internal part of the refrigerant system to

moist air. Residual POE oil in the piping and components can absorb moisture from the air.

Page 47

c) Ensure that the compressor is not expose to open air for more than the recommended time specified by

its manufacturer (typically less than 10 minutes). Removed the seal plugs only when the compressor is about to be brazed.

d) The system should be thoroughly vacuumed to 1.0 Pa ( 700mmHg) or lower. This vacuuming level is

more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.

e) When charging R407C, ensure that only liquid is being withdrawn from the cylinder or can. This is to

ensure that only the original composition of R407C is being delivered into the system. The liquid composition can be different from the vapor composition.

R32 / R125 / R134 23% / 25% / 52% 33% / 33% / 34%

Composition of R407C in vapour phase is different from liquid phase.

f) Normally, the R407C cylinder or can is being equipped with a dip pipe for liquid withdrawal. However, if

the dip pipe is not available, invert the cylinder or can so as to withdraw liquid from the valve at the bottom.

Dip-pipe Invert cylinder

without dip-pipe

Liquid withdrawal

g) When servicing leak, the top up method, commonly practiced for R22 system, is not recommended for

R407C system. Unlike R22 where the refrigerant is of a single component, the composition of R407C, which made up of three different components, may have changed during the leak. Consequently, a top up may not ensure that the R407C in the system is of original composition. This composition shift may adversely affect the system performance. It is recommended that the system should be evacuated thoroughly before recharging with R407C.

Page 48

SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R410A UNIT

1) WHAT IS NEW REFRIGERANT R410A?

R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.

2) COMPONENTS

Mixture of composition by weight : R32(50%) and R125(50%)

3) CHARACTERISTIC

• R410A liquid and vapor components have different compositions when the fluid evaporates or

condenses. Hence, when leak occurs and only vapor leaks out, the composition of the refrigerant mixture left in the system will change and subsequently affect the system performance. DO NOT add new refrigerant to leaked system. It is recommended that the system be evacuated thoroughly before recharging with R410A.

• When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or

liquid phase. Hence when charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to make certain that only original composition of R410A is being charged into the system.

• POE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22

compressor. Extra precaution must be taken to avoid exposing the R410A system to moist air.

4) CHECK LIST BEFORE INSTALLATION / SERVICING

• Tubing

Refrigerant R410A is more easily affected by dust or moisture compared with R22, make sure to temporarily cover the ends of the tubing prior to installation

• Compressor oil

No additional charge of compressor oil is permitted.

• Refrigerant

No other refrigerant other that R410A

• Tools (size of service port is different from R22 system)

Tools specifically for R410A only (must not be used for R22 or other refrigerant) i) Gauge manifold and charging hose ii) Gas leak detector iii) Refrigerant cylinder/charging cylinder iv) Vacuum pump c/w adapter v) Flare tools

vi) Refrigerant recovery machine

5) HANDLING AND INSTALLATION GUIDELINES Like R22 systems, the handling and installation of R410A system are closely similar. All precautionary measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and thorough leak check and vacuuming are equally important requirements.

Page 57

• All terminals and connection must be tightened.

• Avoid any wires from touching the refrigerant pipe. Apply insulation if necessary.

• Avoid any wires from touching the moving components such as, fan motor, pump & compressor.

WARNING

WATER PIPING SYSTEM SETUP

• Fill up the water circuit after connecing all the pipes and equipment. Perform leak checks for all

connections and joints. Do not start the unit when the system is leaking.

• To optimize the capacity of the system, ensure that the system is free of air bubbles.

The air trapped in the system would make the system unbalanced.

• Ensure that the water tank (optional) is not full. This is to ensure optimal performance of the mini chiller. If the pressure is too high, release the air trapped from the auto air vent (on the tank) and manual air vent (installed on the water system).

REFRIGERANT CIRCUIT

• All mini chillers units are pre-charged with R22, R407C or R410A refrigerant. The only piping that needs

to be done is the water piping from mini chiller (outdoor) to the fan coil unit (indoor).

SAFETY AND CAUTION

It is advisable to read through all the safety precautions before installing and commissioning of the unit.

• Contact your dealer for installation, reinstallation or dismantling of unit. Improper handling of unit could result in leaks, electrical shock or unit malfunction.

• Use the controller handset to switch on/off the unit. Do not plug off the main power supply directly, it would cause the unit to breakdown.

• Improper connections and fastening could cause electric shock, short circuit and fire.

• Do not introduce foreign objects such as fingers, sticks etc. into the air inlet and outlet.

• Do not spray any chemical agents or flammable agents to the unit. It would cause fire or explosion.

• Do not climb or place objects on top of the mini chiller.

• Do not operate the chiller with wet hands. It would result in electric shock.

• Do not use fuse of different amperage than stated. Using wire, etc. to replace a fuse could cause

equipment damage or fire.

• Provide proper grounding for the mini chiller. Do not connect the ground wire to gas piping, water piping, lighting rods or telephone ground wire. Improper grounding could cause electrical shock.

• Do not attempt to do any service or maintenance when unit is operating.

• Do not change the settings of the safety devices.

• Do not consume the chilled water in the unit.

• Do not allow water to remain in the water pipes if the unit is not operating for a long period. Water must

be drained out if the unit is not running during winter. Failing to do so would cause the pipe to crack.

• Do not touch the aluminum fin coil. It would damage the coil or cause injury.

• R407C / R410A must be charged as liquid. Usually R407C / R410A cylinder is equipped with a

dip-pipe for liquid withdrawal. If there is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R407C / R410A from the valve.

• Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit

thoroughly and then charge the unit with fresh R407C / R410A according to the amount recommended in the specification.
