The AHU uses the cooled refrigerant incoming through pipes from Chiller to cool the supply air of the cooled area.
The chiller is machine that evaporates liquids through an absorption process. This machine also cooled air and equipement. In others words this machine is and Air-Water Cooling System.
It's transferred to the air which passes through the condenser fins.
It is maintained through the use of a compressor in a graduated cylinder
works by pumping refrigerant, a liquid chemical, through tubes in the cooling cabinet. The refrigerant evaporates there and pulls heat from the air. The gas is pumped out of the cabinet and into the compressor and condenser where the heat is expelled

You cool it and run it through a metering devise.

Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
It will be dependant on you chiller - Look through the manufactiures website in the first instance
when the refrigerant passes through the metering device, some of it starts to flash from a liquid to a gas because
On a low-pressure chiller picture, the rupture disc is located on the evaporator housing. There should not be more than 10-PSIG flowing through this sector at any time.

It increases the efficiency of the system since the amount of heat being removed per pound of refrigerant circulated is greater. In other words, you pump less refrigerant through the system to maintain the refrigerated temperature you want. This reduces the amount of time that the compressor must run to maintain the temperature. The amount of capacity boost which you get with each degree of subcooling varies with the refrigerant being used. Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before it reaches the evaporator. Inadequate subcooling prevents the expansion valve from properly metering liquid refrigerant into the evaporator, resulting in poor system performance.
The refrigerant
The refrigerant itself does.
I guess you have a chiller unit suitable for 380Volts and you have a source voltage of 220V. You can step up 220Volts to 380 volts with a suitable rated step up transformer.
