- Evaporator: 2 units of evaporator with 2 units of variable speed fan motor

- Metering Device: R-134a,

- Fan Motor: 2 units of variable speed condenser fan motor

a) single-phase, 220 to 230VAC/50Hz

b) ON/OFF switch applied to switch on/off fan motor

- 2 units of variable speed evaporator fan motor

a) 1-phase, 220 to 230VAC/50Hz

b) ON/OFF switch applied to switch on/off fan motor

- Shut Off Valve (Hand Valve), Applied to make it function:

a) using single evaporator with single condenser

b) using single evaporator with double condenser

c) using double evaporator with single condenser

d) using double evaporator with double condenser

- Pressure Transmitter: Applied to all inlet and outlet of compressors.

- Sight Glass: Applied to all inlet and outlet of compressor, condensers and evaporators.

- Flow meter: Used to measure the refrigerant flow rate.

- High and Low Pressure Switch: It is the electrical control switch operated by change in pressure.

It is automatically open electrical circuit if pressure is too high or too low. Depend on system configurations.
- Control Panel: The control panel consists of:

a) Voltmeter, it is used to measure the voltage consumption by air conditioning system.

b) Ammeter, it is used to measure the current consumption by air conditioning system.

c) Fuse, used to protect the component or circuit from over current.

d) Indicators are used to display temperature and refrigerant flow rate pressure of air conditioning System.
