A well-structured air conditioner plant can considerably decrease energy consumption
In today's posting, we will resume some basic concepts regarding large air conditioning centers so that we can understand how a well-structured design can considerably lower energy consumption compared to other air conditioning systems.
Initially, we should understand that there is a triad in a central air conditioner, which involves: air conditioning, refrigeration and ventilation.
The air conditioning treats the air, adjusting its temperature in values, usually above 20 ° C. can control, in addition to the air temperature in the enclosure, the internal pressure, the purity of the air (filtering) and its relative humidity. The air conditioning can be used with environmental comfort (as in use bulk companies and trades, hospitals, clinics, etc.) or industrial, to control process variables (in the weaving and graphic industry - controlling temperature and humidity; in the electronic industry - Controlling temperature, humidity, air purity and enclosure pressure, among other cases).
The refrigeration process relates to air autilization as fluid for temperature control. In this case, the air is cooled at temperatures close to 0 ° C and can reach temperatures below -10 ° C. As typical applications, there are the use of chambers or refrigerator counters.
Finally, the ventilation process on the air that is introduced into an environment to control its temperature, always limited in relation to the outdoor air temperature, removing the thermal energy generated within it by persons, equipment, etc. In this case, there is no way to control the temperature at a fixed value. Ventilation is also used to remove pollutants and odors, being ideal for increasing the asepsis of hospital locations, in which there is a high level of proliferation of bacteria.
In view of these numerous functions that a central air conditioner can play in a certain place, it is important to have the consciousness that this is also the largest responsible for the energy consumption of this environment. That is, the increase in the use of air conditioning leads to the consequent increase in energy consumption. However, when carrying out a well-structured and adequate project to place where air conditioning will be carried out, this energy consumption can be considerably reduced by bringing positive impacts on the energy bill by lowering it relevant.
For this, it is necessary, initially, to study which appliances is most suitable for each place, taking into account the size of the environment, the flow of people and the specific needs of the locality. To have a idea, there are types of air conditioning plants that, through frequency inversion, can save up to 40% energy consumption from that place compared to other models. In this sense, the way the appliance is installed totally in energy expenditure, since a correct installation will favor the operation of air conditioning, interfering with productivity and the consequent reduction of energy consumption.
When there is already the operation of an air conditioning system, there is also the possibility of a study of energy consumption and detect what are the best ways to lower it. For this, there is the so-called energy diagnosis, which is a tool used to raise and estimate how and in what quantities the various forms of energy are being spent on a building, in their systems (air conditioning, lighting, motorization, pumping, refrigeration, etc. .) or in industrial applications, in their processes (compressed air, steam, pumping, etc.). After the survey, study is made that allows to evaluate losses (translated into consumption of kWh, demand, etc.), their costs and indicate corrective measures, evaluate costs of investment nasium (projects, acquisition of new equipment), calculate return time Investments, aiming to guide the managers from the venture in decision-making.
Therefore, as we reflect from this article and the others already posted on our blog, invest in an adequate air conditioning center project for your company, industry, clinic or hospital, or make a study established from the facilities already made, is more of what beneficial, is essential. An efficient air conditioning center and well structure can, in addition to ensuring a greater purity of the air circulating in the environments in which it works, also reducing energy expenditure, providing more health and more economy.
