Water Cooled Chillers
Contact Us Today For The Perfect Cooling Solution
Water cooled chiller is a cooling method of chiller, which can emit heat to cool the water used in projects and industrial structures, and re-enter the operation cycle. In fact, the chiller transfers heat from the space requiring temperature control to another space. Therefore, the chiller is not a means of generating cold, but a means of heat dissipation. Its task is to transfer heat to places outside the system.
The cooling tower is specially designed for the water-cooled chiller, because the condenser of the water-cooled chiller uses water as the stimulation and cooling material. Because the wet surface is more successful in heat transfer and can also perform compression function at wetter temperatures, the efficiency of water-cooled chillers will be higher.

Difference between Air Cooled Chiller and Water Cooled Chiller
1. In terms of the size of the equipment, due to the difference in the working principle between the two, the air-cooled chiller is smaller than the water-cooled chiller in terms of the size of the equipment, and the use and later maintenance Also relatively simpler.
2. From the perspective of the efficiency of the equipment, the cooling effect of the water-cooled chiller is stronger than that of the air-cooled chiller, and the power consumption is also less.
3. The price of water-cooled chillers is relatively low, but a special equipment room needs to be built in use, while air-cooled chillers do not. Therefore, if there is no suitable venue, it is more suitable to choose air-cooled equipment.
The Working Process of Water Cooled Chillers
The water-cooled chiller comes into play during the evaporation process, the water and gas produced are brought to the evaporator and all the unwanted heat is collected on the way, and then returned to the evaporator and the obtained heat energy is stored. After that, the refrigerant collects this heat and transfers it to the condensate, that is, the condenser sends all the collected heat to the cooling tower, and finally the hot air is released to the atmosphere through the cooling coil.
The First Stage:
The starting point of this cycle is when the water from the production process enters the evaporator and enters the cooling cycle.
In this part of the cycle, the heat absorbed by the refrigerant first comes in the form of liquid to gas. As the refrigerant absorbs the heat of the water, the temperature of the environment in contact with this part drops, so the water leaves at a lower temperature. This water enters the fan coil and brings the cool air to the desired space.
In fact, the evaporator is a place that participates in another cycle besides the current cycle, which is located between the evaporator and the water outlet of the cooling device. In fact, the hot water goes to the chiller evaporator, which then cools it down.
The Second Stage:
The gaseous refrigerant reaches the gas phase in a pre-liquid state and then enters the compressor. In the compressor, the condensing temperature and pressure of the gas are increased so that it can enter the next high pressure stage. The rise in pressure and temperature as it leaves the compressor is important because the refrigerant needs to release heat from inside the condenser, so it must carry enough heat to the condenser.
Another key function of the compressor is to draw refrigerant into the evaporator at the right time, keeping the pressure inside the evaporator high enough to absorb heat again.
The Third Stage:
The high-temperature gas enters the condenser, where the gaseous refrigerant is converted into a saturated high-pressure liquid. This is a constant pressure process.
Since the condenser exists in another cycle between the cooling towers, the water enters the cooling towers after the temperature rises. Because the main task of the cooling tower in a water-cooled chiller is to cool the consumed water, and the condenser uses this water as its driving material.
Where the excess heat of the water is lost, the water temperature returns to the desired low temperature. The heating process we mentioned earlier takes place in the condenser, releasing the gaseous refrigerant from the heat itself, which is the heat source in question and needs to be removed by a cooling tower. In this way, the water entering the cooling tower from the condenser comes into contact with the airflow, transfers heat to the air, and returns to the condenser.
The Fourth Stage:
The expansion valve is the last stage of the refrigerant, in the refrigerant in the expansion valve these processes take place causing the refrigerant to become a mixture of liquid and gas, the same compound re-enters the evaporator to resume the cycle, and the hot water re-enters from the other direction Evaporator.
Water-cooled chillers are used in hospitals, airports, manufacturing plants, industrial plants, pharmaceutical and chemical industries, biotechnology, military industry, aerospace and other fields, all of which are carried out on the premise that water is required. The problem with water-cooled chillers is that they use a lot of water and are not suitable for use in water-scarce areas.
