Modern cooling system theory
The demands on engine cooling systems have risen dramatically over the past two decades. Factors that have driven this rising demand are an increase in the number of fluids that need cooling, a push for higher power output, and the implementation of stricter emissions regulations. As both initial capital costs and operating costs continue to increase for cooling systems, so has the awareness of ...

Fans and fuel
One of the fun things about researching articles is how you can end up in a totally different place than where you started. A few weeks ago, I was working on a story for the October issue of HDT on oil and coolant analysis. That led to what I'm going to talk about today, which is fans and fuel economy. It started out when I was talking to Mike Tourville with Evans, which makes a waterless ...

Thermodynamic analyses of advanced desiccant cooling systems with various configurations
Six configurations of conventional and advanced desiccant cooling systems are presented, analysed and compared thermodynamically. The advanced systems are modified forms of the conventional systems. These advanced systems are desiccant cooling systems in the ventilation mode (ADV), the modified ventilation mode (ADMV) and the recirculation mode (ADR). For each configuration, a thermodynamic model ...

Are you `cooling challenged?`
Although the Technology and Maintenance Council’s (TMC) taskforce looking into EGR cooler maintenance has not issued a “Recommended Practice,” from the literature and Internet searches, it seems heavy-duty diesels are by and large not susceptible to cooler problems. It’s the medium-duty trucks and Ford diesel pickups that are most troubled. The power units in question are ...

Experimental study on an open cycle desiccant cooling system
This paper presents the design and construction of an experimental desiccant cooling system that uses natural zeolite as the desiccant. This is the first use of this desiccant in an actual or experimental system. The primary system components are originally designed and constructed. The paper provides a sufficient detail on the design procedure of the components as well as the methods of ...

Audits of secondary cooling systems in existing casters as a method to enhance product quality and productivity
Over the life span of a continuous casting machine the requirements in terms of production output, product quality and the range of steel grades may change significantly. Consistent porduction of prime quality over the extended steel grade range requires an increased operational and maintenance flexibility which can be missing from existing casters. The secondary cooling system is a key ...

Exergetic performance evaluation of ejector cooling system
Ejector-cooling model is developed to calculate the entrainment ratio and the area ratio representing throat to nozzle area. The developed model is validated with available experimental data in the literature. Parametric studies using the refrigerant R134a as the working fluid show that the Coefficient of Performance (COP) of the system is increased by increasing the generator and evaporator ...

Leading IT Provider Simplifies Logistics with Our Closed-Loop Cooling System
Black Box turned to Thermal Edge in 2011 when other cooling systems failed to protect networking equipment housed in their electrical cabinets. Black Box’s previous cooling system had internal analog controls, which exposed equipment to external contaminates when service personnel opened cabinet doors to make adjustments. They also needed to be installed near a drain to manage condensation. ...

A study on the exergetic and environmental effects of commercial cooling systems
This study examines the effects of exergy efficiencies for three different cooling systems used commonly in commercial applications like hypermarkets. Additionally, environmental effects depending on the Total Equivalent Warming Impact (TEWI) in each system are calculated. In the analysis, considered under constant load, R22, R502, R134a, R404a and R507 refrigerants, and R407 and R410 alternative ...

OEM off-highway `You`re an enabler`
OEMs are spending large sums of money in order to meet the continually tightening regulations in regards to fuel consumption and emissions reduction. The sheer size of equipment on top of high productivity demands causes frequent overheating—sometimes daily depending on the conditions. Evans Cooling Systems Inc., Sharon, CT, offers a coolant without water which allows equipment to run ...

Minimizing Your Plant`s Electrical Maintenance Issues with Proper Cabinet Cooling Systems
Your electrical equipment needs to be sheltered from harsh environments and extreme conditions. Electrical enclosures do a great job of keeping the electronics shielded from contaminants, such as dirt or moisture. But what about the heat produced by the equipment themselves? Choosing the right cabinet cooling system will help decrease unplanned maintenance by keeping the equipment in proper ...

ADVANTAGES OF HITEMA FREECOOLING
The free cooling system used by Hitema International is in partial mode. This system allows to use the most of the low temperatures of the winter months and also offers significant advantages in terms of energy savings even in transition seasons such as autumn or spring. The use of free cooling technology allows users to achieve a reliable payback time compared to traditional water chillers. ...

Cooling Towers and Cooling Systems
Water is used widely as a cooling medium in processes for many industries and public buildings. The use of an evaporative cooling tower is still the most effective method of heat transfer. Heat is transferred from hot process fluids into the cooling water through a heat exchange surface; consequently, the cooling water heats up. The evaporation of a small percentage of this cooling water in a ...

Solar Desiccant Cooling Systems
Desiccant cooling systems are basically open cycle systems, using water as refrigerant in direct contact with air. The thermally driven cooling cycle is a combination of evaporative cooling with air dehumidification by a desiccant material. For this purpose, liquid or solid materials can be used. The term ‘open’ is used to indicate that the refrigerant is discarded from the system ...

Summer–time thermal comfort in vernacular earth dwellings in Yazd, Iran
There is widespread assumption that vernacular earth dwellings in hot climates, particularly those in central Iran are climate–responsive and provide thermal comfort in hot periods even without the aid of electro–mechanical cooling systems. The paper describes two surveys undertaken to investigate the provision of comfortable indoor temperatures in vernacular central–courtyard ...

Energy and exergy analyses of an integrated fuel cell and absorption cooling system
In this study, we carry out detailed energy and exergy analyses of a PEM fuel cell integrated with triple effect ammonia-water absorption cooling system and investigate the effect of different operating parameters such as pressure, temperature, membrane thickness and current density of the fuel cell on the outputs of the fuel cell, and COP of the cooling system. The results show that fuel cell ...
