WHAT ARE THE CONSEQUENCES OF A COOLING TOWER OPERATING AT LOW EFFICIENCY? Cooling tower detailed calculations A low efficient cooling tower brings very serious consequences. Bruno Neri The tower is part of a system designed to dispose residual waste heat from the Read More
HOW TO MEASURE THE EFFICIENCY OF A COOLING TOWER In the design process of a cooling tower there is a need to have at least seven data values, or rather 7 variables. If only one of these values is changed, the 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
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. We 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) removed from 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 these 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
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
