Large power reactors [1] [2] use dry, wet or hybrid cooling towers when the cooling system is closed. The choice of a type of cooling tower depends essentially on the characteristics of the site
Results showed that for the system analyzed, the energy saving of optimizing the cooling tower fan system was found to be 12–15%, while the energy saving potential of optimizing the condenser

Cooling water is circulating in the coils without any contact with the ambient air so that the water can be kept
Like forced draft cooling towers, induced draft cooling towers employ fans to pull air through the tower. They are usually larger than forced draft cooling towers with fans on top of the tower. The name of this type of cooling tower hints at its operation mechanism: the fans located on top of the tower induce moist and warm air out of the tower
The trade-off actions between the power consumption of the chillers and cooling tower fans can also be considered for further enhancement of the cooling system performance. Overall, the selection of models for the cooling towers and chillers system, the subsequent analysis, and trade-off considerations in this study can be regarded as a
The overall system model was then optimized using a generalized reduced gradient optimization algorithm to determine the potential energy savings through speed control with VFDs and to ascertain a control logic strategy for the building automation system to operate the heating and cooling system. A case-study was performed on a single chiller
The transient nature of the cycling cooling tower fan would undermine a steady state model; thus, the data from 9/27–10/30 was removed for training the cooling tower model. As a result, the entire cooling tower dataset was comprised of only one value for both the air and water volumetric flow rates.
Thus, the effectiveness cooling tower model by Braun is adopted to model the cooling tower performance with field measurements. A typical electric chiller model based on the condenser entering temperature is applied from the EnergyPlus Engineering Reference. These two models are integrated to determine the optimal operation for the cooling system.
However, some cooling towers consume up to 45 kW el /MW th of electricity (DIN SPEC 15240, 2019, p. 53) or up to 4.5 m 3 /h/MW th of water (Hincke & Hainbach, 2018, pp. 330−335), whereas once-through cooling requires 10 to 100 times more water than cooling towers (European Commission, 2001, p. 72; Macknick et al., 2012, p. 6).

Cooling towers are an essential component of industrial power plants and air conditioning systems. In comparing different types of cooling processes, evaporative cooling is the most effective method of rejecting low-grade heat to the environment [1].Therefore, wet cooling towers – in which heat transfer occurs due to both sensible and, more significantly, latent
In this paper the use of a dry Heller cooling system is proposed to diminish the water consumption of a concentrated solar tower power plant. The Heller system is an indirect cooling system where
variable-speed-driven cooling tower fans, and a variety of control strategies have been proposed to optimize cooling tower fan operation [3],[4],[5],[6],[7]. These strategies generally focus on controlling the cooling tower fan based on cooling load and/or ambient weather conditions. Variable-speed-driven evaporator pumps have been examined

This paper is an overview of the data center''s cooling system, which mainly includes the mainstream cooling solutions, the power consumption modeling methods and the optimization control strategies.
Furthermore, Marugán-cruz and Santana [43] proposed a dry Heller cooling system (indirect cooling system) to reduce the water consumption of a solar power tower (SPT) plant. The study demonstrated that this system was able to reduce water consumption by more than 1.4 × 10 6 m 3 /year compared to WCTs.
The pump-head of a cooling tower also contributes to the energy expended in the operation of the condenser water pump. Obviously, therefore, manipulation of one, or both, of these power consuming aspects as a means of adjusting for changing loads or ambient conditions should have some beneficial effect upon the cooling tower''s energy requirement.

A refrigeration system based on cooling towers does not only involve the cooling towers themselves, but also a set of equipment that operate interdependently, such as chillers. we present the model of the cooling tower as well as that of the tower fans. Later, in Sect. Result of modeling the power consumption of cooling tower fans in
minimum energy consumption of the cooling system. Zhang [15] used a new type of radiator inside the cooling tower as a cold source to calculate and analyze the annual energy consumption of the cooling system; however, they did not consider the impact of ambient relative humidity on the energy consumption of the cooling system.
The paper presents optimization model of the chilled water based data center cooling system. The optimization procedure includes system technological and mathematical model, limiting conditions and optimization criterion, which in this case is annual power consumption minimum. The cooling system model is defined by constant
Power consumption modeling takes the measurable variables as inputs to estimate the power consumption of the cooling equipment. As illustrated by Fig. 1, the chiller and the fans of the CRAC are the main power consumers of the cooling system, so their power consumption model will be reviewed here.
STRATEGIES FOR REDUCING COOLING TOWER ENERGY CONSUMPTION 4.1. Cooling tower slack 11 During colder days, if a cooling tower operates with the design air flow rate, the water is cooled below 30 oC, and in other to reach this value, it is necessary to use a reduced air flow rate (Gred,t1) calculated as a function of the ambient WBT.
The wet cooling tower is a critical component in dissipating excess heat from the water used in condensers to the atmosphere through heat exchange with the air, mainly utilized in power systems, petroleum oil plants, food processing plants, chemical industries, and smelting industries [1,2,3].The heat absorbed by the air in cooling towers is equivalent to the heat
As for T a p p, it influences both the cooling towers and chillers in different situations.Therefore, T a p p can be continuously adjusted to maximize the cooling system performance under varying conditions for variable-speed cooling towers. Yao et al utilized a fitted equation to find the optimal condenser inlet water temperature set point and T a p p.This
of the wet cooling tower at the 30% of the total cooling load would minimise the overall system costs. Rezaei et al. [9] developed a numerical model of a hybrid cooling system and built a pilot setup to investigate experimentally the water losses considering the series and parallel operation modes in an industrial plant.
Cooling towers can differ by build as well as heat transfer and air generation methods. When it comes to cooling tower build, there is the: Package type. These are small, compact, and pre-fabricated cooling towers used for smaller industries, such as hospitals or schools. These are factory-fabricated and shipped on trucks. Field erection type
Cooling tower plays an important role in the air conditioning system and in power plants. Cooling tower is a steady-flow mechanical device that is used to cool the heated water with from the different heat exchangers. Cooling occurs with the loss of latent heat of the water, which, in turn, leads to evaporation.
This article explores the key aspects of cooling tower operations, focusing on their efficiency, design considerations, and the underlying thermodynamics. Understanding Cooling Tower Efficiency. The efficiency of a cooling tower is determined by its ability to lower the temperature of water close to the wet-bulb temperature of the surrounding air.
