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
Why recycle water used for cooling industrial plants? Water is a precious resource. Wasting water, besides being a waste of money, precludes resources otherwise used for the benefits of all. For example, irrigation systems, sources of drinking water, and so on will be Read More
Process plants that can be cooled with evaporation systems. The importance of disposing quantity of energy. Efficiency of the cooling system. Image from previous post “NERI Calculator”. Click on the above image to learn more about the calculator. From what has been written on this 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
COOLING WATER The concept of temperature and heat Temperature is a physical quantity that expresses the thermal state of an object. It is closely correlated to the amount of heat contained in the object itself. A hot body is characterized by the Read More
