Water-cooled chiller having water-cooled shell and tube type condenser, water chiller, and the cooling tower will help the whole water cooling system to be more effective and high performance.
A water-cooled chiller system connects the evaporator to the condenser. It keeps the heat moving out of the evaporator and into the water-cooled chiller condenser, but the two water lines never interact with each other.
The hot water here, we called condenser water, travels up into the riser and heads towards the cooling tower on the roof. Once there, the condenser water flows through the cooling tower, and fans pull in ambient air to transfer heat out of the water.
After cooling off a bit, the condenser water returns to the condenser cylinder at a lower temperature.

TopChiller provides all sets of water cooling systems including a chiller with a cooling tower and circulation water pumps.
For chillers, we have more phases and enough explanation in previous pages.
On this page, we will move into the cooling tower topic.
Cooling towers are devices that use air in contact with water (directly or indirectly) to cool water. Water is used as a circulating coolant to absorb heat from a system and discharge it into the atmosphere, thereby lowering the temperature in the tower and manufacturing equipment for circulating cooling water.

Basic working principle of cooling tower
A cooling tower is a device that uses air (indirect or indirect) contact with water to cool water.
Water is used as a circulating coolant to absorb heat from a system and discharge it into the atmosphere, thereby reducing the temperature inside the tower and making equipment that can be recycled for cooling water.
Evaporative heat dissipation is accomplished by mass exchange, which is achieved by the continuous diffusion of water molecules into the air.
Water molecules have different energies, and the average energy is determined by the water temperature.
Some water molecules with large kinetic energy near the surface of the water overcome the attraction of the adjacent water molecules and escape from the water surface to become water vapor.
The water molecules near the water surface escape due to the energy of large water molecules. The energy is getting smaller.
Therefore, the water temperature is lowered, which is the evaporative heat dissipation. It is generally believed that the evaporated water molecules first form a thin layer of saturated air on the surface of the water, the temperature of which is the same as the water surface temperature, and then the speed at which the water vapor diffuses from the saturated layer to the atmosphere depends on the speed.
The difference between the water vapor pressure of the saturated layer and the water vapor pressure of the atmosphere, that is, Dolton’s law,

Crossflow square cooling tower
You will find how to install a cooling tower from this video. We can follow this installation guide when installing a cooling tower.
TopChiller provides a full range of a variety of cooling towers from 50Ton to 500Ton capacity.
Crossflow closed cooling tower
Crossflow Closed Cooling Tower
The cross-flow closed cooling tower is an evaporative cooling tower, a combination of a cooler and a wet cooling tower.
It is a horizontal evaporative cooling tower. The process fluid flows through the tube and the air flows outside the tube. contact.
The water in the bottom reservoir is pumped by the circulation pump and sent to the outside of the pipe for uniform spraying.
It does not come into contact with the process fluid hot water or refrigerant and the outside air and becomes a closed cooling tower, which enhances the heat and mass transfer effect by spraying water.
The cross-flow closed cooling tower uses steel plates as the main structure and an additional steel structure frame inside.
The product is a dual fan structure, and the dual fan is driven by the same motor through a belt reducer. Compared with the cross-flow FRP cooling tower.
The biggest difference between this product is that the coil and the packing are completely different, and the circulating water is completely closed.
The most advantage of using a cross-flow closed cooling tower is to save water consumption and the circulation water is always clean without dust.
Besides a cross-flow closed cooling tower, TopChiller can also supply an evaporative cooling tower.
Evaporative Cooling Tower
The evaporative cooling tower is a highly efficient heat exchange device. Due to its high heat transfer efficiency, energy-saving, compact structure, and easy installation.
The evaporation absorption (latent heat) of water of equal mass at room temperature is 115 times that of water absorption by 5 °C, which is the root cause of water-saving and power-saving of the evaporative cooling tower.
This kind of evaporative cooling tower is widely used in large-scale chemical, pharmaceutical, steel, air conditioning, coal, nitrogen, and other aspects.
There are also practices in gas cooling, condensation, and liquid cooling in processes such as ammonia synthesis, methanol synthesis, gas compression, distillation, and waste heat recovery.
How does the evaporative condenser or evaporative cooling tower work?
Mainly utilizes the evaporation of a part of the water to take away the heat released by the condensation process of the gaseous refrigerant.
The high-temperature gaseous refrigerant enters the coil from the refrigerant inlet at the upper part of the coil, exchanges heat with the spray water and air outside the coil, and is gradually replaced by the gaseous state.
Condensate into a liquid state and flow out from the lower refrigerant outlet. The cooling water is sent by the water pump to the spraying system above the condensing coil and is evenly sprayed on the outer surface of the condensing coil by the water distributor to form a thin water film.
The temperature rises after the spray water and air absorb heat. Part of the water changes from liquid to gas and a large amount of heat is taken from the evaporation’s submerged zone.
The rest of the waterfalls back to the lower sump and is recycled by the circulating water pump into the sprinkler system; the water droplets entrained in the air are blocked by the dehydrator. , fell back to the catchment.
Evaporative Cooling Tower Working
Structural features of the evaporative cooling tower:
Countercurrent evaporative cooling: It is an evaporative cooling that uses only the latent heat exchange of water.
It has a large heat exchange area, is not easy to produce ice blockage and dirty plugging, and can operate in various environments, especially in drought-deficient areas. Well, the dry-running operation in winter is better.
The inlet air is in the form of a bottom countercurrent inlet, which alternates with the lower spray water to form saturated hot and humid air.
The heat is discharged from the top fan, and the water has a special structure of the dehydrator to reclaim the sump for recycling, and the internal space has no heat exchange filler to vacate More space increases the unit’s heat dissipation area.
The structure is more compact and the footprint is small. It is especially suitable for situations where the effluent temperature requirement is close to the local wet bulb temperature.
Application field of the evaporative cooling tower:
It is widely used in gas cooling, condensation, and liquid cooling in large-scale chemical, pharmaceutical, steel, air conditioning, coal, nitrogen fertilizer, ammonia synthesis, methanol synthesis, gas compression, distillation, and waste heat recovery processes.
The condenser tube is a round tube with high heat transfer efficiency, and the outer sheath of the box is a double-sided anti-corrosion effect of the galvanized steel plate.
The water pump, the fan, and the motor thereof are well-known brands in China; the fan adopts a wing-shaped hollow aluminum alloy blade, and the top of the fan is provided with a mesh protective cover;
the motor is temperature-resistant, moisture- and moisture-proof, and the protection grade is IP55.
The Evaporative cooling tower is structurally related to the combination of a common water-cooled condenser, cooling tower, water pump, and water system.
It has energy-saving, water-saving, and convenient installation. Small footprint and easy maintenance. But there are essential differences in the heat transfer principle.
The water-cooled evaporative condenser uses the sensible heat of the water to absorb the heat of the refrigerant to achieve the purpose of cooling, and the evaporative cooling uses the latent heat of water, that is, the evaporation of water at normal temperature to absorb the heat for cooling purposes, and the same quality of water is absorbed by evaporation.
The heat is 116 times the heat when the water temperature rises by 5 degrees, so the evaporation of cold is much lower than that of the water-cooled condenser when taking away the same heat, which is also the root cause of evaporative cooling and water saving.
Cooling Tower Features
Advantages of the evaporative cooling tower over round open type cooling tower:
1. Under the same host and the same working conditions, compared with the energy consumption of the open cooling tower and the evaporative cooling tower, the energy consumption of the evaporative cooling tower must be greater than that of the open cooling tower.
If you need to analyze the system energy consumption and cost in detail, you need to stand in the entire system condensation section for energy consumption and cost analysis comparison.
One unit of evaporative cooling tower solves the condensation requirement of the whole refrigeration system; the simple open cooling tower is only a part of the whole condensing section system.
The water cooling system equipment mainly includes the shell-and-tube condenser, cooling water pump, and cooling towers, etc., the cost needs to be combined with the analysis of the entire water cooling system.
The energy consumption needs to add to the energy consumption of the cooling water pump and the open cooling tower.
a. Evaporative cooling tower energy-consuming equipment includes a spray water pump and a heat-dissipating fan; the cooling tower energy-consuming equipment only includes a heat-dissipating fan.
b. The main heat exchange equipment of the evaporative cooling tower is an indirect heat exchange mode, and the thermal resistance includes convective heat transfer on the refrigerant side, heat transfer in the heat exchanger, and convective heat transfer of the spray water.
But the open cooling tower The heat exchange mode is that the cooling water directly exchanges heat with the air, and the heat exchange effect is better than the indirect heat transfer.
2. In the case of the same cooling capacity, the evaporative cooling tower can achieve a lower condensation temperature than the conventional water cooling system, and the compressor consumes less energy when the same cooling capacity is achieved.
In the long-term operation of the refrigeration system, energy-saving and operating costs are reduced.
Selection and Sizing of Your Cooling Tower
The parameters to be measured are air wet bulb temperature, air dry bulb temperature, cooling tower inlet water temperature, cooling tower outlet water temperature, exhaust temperature, pump and motor operation parameters, water flow velocity, and airflow velocity.
- Operating parameters: cooling water temperature difference, cooling range, efficiency, cooling tower capacity, recharge water flow, cooling water flow, type selection, cooling tower type selection, and design issues.
- Cooling Water Temperature Difference: Inlet Temperature-Outlet Temperature Large Temperature Difference = High Performance
Cold Amplitude: The Difference between the Outlet Temperature of Cooling Tower and the Wet Ball Temperature of Inlet Air: Small Cold Amplitude = High Performance, Efficiency:
4. Cooling tower capacity
The capacity unit of the cooling tower is “kilocalorie per hour” or “cold ton”.
Cooling tower capacity = cooling water mass flow * specific heat capacity * temperature difference.
High capacity = high performance
5. Calculating the amount of recharge water
Water loss by evaporation (E)
E = Q/600 = T1-T2 * L/600
E represents evaporative water volume (kg/h);
Q stands for heat load (Kcal/h);
600 represents the latent heat of water evaporation (Kcal/h);
T1 represents the inlet temperature (?) and T2 represents the outlet temperature (?).
L represents the amount of circulating water (kg/h).
Splash loss water (C): Splash loss of cooling tower depends on the design type of cooling tower, wind speed, and other factors. Normally, its value is about 0.1-0.2% of the circulating water.
Periodic Discharge Water Loss (D): Periodic Discharge Water Loss depends on factors such as water quality or solids concentration in water. Generally, it is about 0.3% of circulating water.
M = E + C + D
Evaporation loss of water (E), splash loss of water (C), and regular discharge loss of water (D).
When the cooling tower is used for air conditioning, the temperature difference is designed at 5 C. At this time, the recharge water needed for the cooling tower is about 2% of the circulating water.
6. Cooling water flow
K. Q = C. M. T
K: Estimation coefficient
Q: Maximum refrigeration capacity of the unit
C: Specific heat capacity of water
T: The Temperature difference between supply and return water
M: Cooling water quality and flow rate
The maximum refrigeration capacity of the compressed refrigeration unit is 1.3 times.
The refrigeration capacity of the absorption refrigeration unit (lithium bromide) is 2.5 times.
Cooling Tower Sizing
Permanent Design of Cooling Tower Type Selection
- 1. Determinants of cooling tower energy consumption?
Answer: Fan power, cooling water flow, cooling water supply?
- 2. Under the temperature condition of the cooling tower, which temperature is the most economical and efficient?
Answer: The inlet temperature of the cooling tower varies according to the different conditions of use.
For example, the outlet temperature of the central air conditioning condenser is generally 30-40 C, while the outlet temperature of the cooling tower is generally 30 C.
The ideal cooling temperature (return water temperature) of the cooling tower is 2-3 C higher than the wet-bulb temperature.
This value is called an “approximation degree”. The smaller the approximation degree, the better the cooling effect and the more economical the cooling tower is.
- 3. Comparison of Open and Closed Types
Open-end: The initial investment is relatively small, but the operation cost is higher (water consumption, electricity consumption).
Closed type: This equipment is suitable for use in a severe environments such as drought, water shortage, frequent sandstorms, and so on. It can cool many kinds of media, such as water, oil, alcohol, quenching liquid, brine, and chemical liquid.
The medium has no loss and stable composition. Low energy consumption.
Disadvantage: Closed cooling towers cost three times as much as open ones.
Preparation before operation a cooling tower:
1) Exclude foreign matter on the side of the air inlet or around the wind;
2) Make sure there is enough clearance between the tail of the windmill and the windshield to avoid damage during operation;
3) Check if the V-belt of the reducer is properly adjusted;
4) The position of the V-belt pulleys must be at the same level with each other;
5) After the above inspection is completed, start the switch intermittently to check whether the windmill operation mode is correct? And is there any abnormal noise vibration?
6) Remove the hot water tray and the internal debris of the tower body;
7) Remove the dirt and foreign matter in the hot water tray, and then fill the water to the overflow position;
8) intermittently start the circulating water pump to remove the air inside the pipe until the pipe and the cold water pan are filled with circulating water;
9) When the circulating water pump is in normal operation, the water level in the cold water pan will drop slightly. At this time, the float valve must be adjusted to a certain water level;
10) Circuitry, reconfirm that the circuit switch, fuse, and wiring specifications match the motor load.
Water cooling tower starting precautions:
a. Start the windmill intermittently, check if it is reverse running or abnormal noise vibration occurs? Then start the pump again;
b. Check if the running current of the windmill motor is overloaded? Avoid motor burnout or voltage drop;
c. Use the control valve to adjust the water volume to keep the water level of the hot water tray between 30~50mm;
d. Check if the running water level in the cold water tray is normal.
Precautions during the operation of the cooling tower:
a. After 5~6 days of operation, check whether the V-belt of the windmill reducer is normal? If it is slack, it can be properly locked with the adjusting bolts;
b. After one week of operation of the cooling tower, the circulating water must be replaced again to remove the dirt and dirt in the pipeline;
c. The cooling efficiency of the cooling tower will be affected by the circulating water level. For this reason, it is necessary to ensure a certain water level of the hot water tray;
d. If the water level in the cold water tray drops, the performance of the circulating water pump and the air conditioner will be affected, so the water level must also be kept constant;
How to maintenance your cooling tower?
The circulating water is generally replaced once a month, or it may have to be replaced if it is dirty. The replacement of circulating the water is determined according to the concentration of solids in the water.
At the same time, the hot water tray and the cold water tray are cleaned, and if there is dirt in the hot water tray, it Will affects the cooling efficiency.
Water tower seasonal shutdown maintenance notes:
a. Relax the V-belt in the reducer and fill the bearing with lubricating oil;
b. All the circulating water of the pipeline must be removed to avoid cracking caused by freezing in winter. The drain pipe of the cold water tray can be opened at any time so that rainwater and dissolved snow can flow out;
c. After the cooling tower is restarted for some time, it is necessary to check whether the motor insulation is normal. Then refer to the instructions for pre-operation preparation.
