The system that allows used water that was heated during the cooling of a technological system to be cooled, thus making it again, and continuously, available to give continuity to the cooling cycles, is called “evaporative cooling tower”. Liquid refrigerant cooling is Read More
Water as a means of energy-heat transportation Excessive heat not used by machines must be removed. This is important to avoid accumulated heat and, hence, compromise the functioning of the machines. One would think that a quick remedy for this type of Read More
We like to thank everyone for visiting our blog and have shared our experience in Cooling Tower industry. Up to today, our blog “Cooling Tower“, containing 84 posts, was seen approximately by 3000 visitors 7000 times, of which some visited the blog Read More
COOLING TOWER Cooling tower design require water and air related data. Data concerning the water include flow rate, water temperature going into the tower, and temperature going out of the tower. This data is provided by the cooling tower plant design. Data Read More
SYSTEMS THAT COOL WATER IN AN EVAPORATIVE WAY: WHERE THEY ARE USED A hint is given by knowing how refrigerators function in terms of “transfer of energy-heat”. Although this topic is very interesting, we will not linger on the quality of energy. Read More
Evaporation The amount of evaporated water in the surface portion dA can be expressed through the relationship: dL = kv (psat – pv) dA where kv is the evaporation function index. The following expression describes the amount of heat (QD) Read More
Here is an example of systems of differentiation for water cooling at low temperature required for realizing specific production processes: cooling plastic material molds, air conditioning, etc. In some plants, cooling towers are not recommended for cooling machines. This is because Read More
EVAPORATION OF A FLUID INTO GAS The following discussion is based on the following assumptions: (1) Inside the water there is no heat exchange; (2) The water that has decreased in volume, due to the evaporation effect, will be replenished with the Read More
UP TO WHAT TEMPERATURE CAN WATER BE COOLED The capacity of air to cool water, according to latent heat. Practical benefits. The physical states are well known: solid, liquid, gaseous. When an element goes from one physical state to another, it frees Read More
Water cooling takes place according to three phenomena: 1. CONDUCTION: (disposal of sensible heat1). The heat flows from a region with a higher temperature to a region with a lower temperature through one or more means that are in direct physical contact, Read More
