The clean air rate and temperature level of the environments we live in have a significant impact on our motivation as well as our health. Being between four walls increases our need for fresh air. In our world where seasonal changes are experienced, we want to be less exposed to this change in our homes and workplaces. In short, we want to warm up in the winter and cool down in the summer. While we meet our need for heating indoors on winter days, we also need fresh air flow. The need for heat and cold is not just for humans and other living things. Our food and beverages should also have special protection areas according to seasonal conditions. We must provide the necessary heat for the products to preserve their freshness and not spoil. The actions of keeping the cold with the ice, which is one of the oldest methods, and conserving the heat by using the underground have left their place to the heating and cooling systems due to their impracticality, short-term and troublesome reasons.
With the development of technology, heating and cooling systems in almost every environment make our lives easier. It has become one of our important energy systems. Actions such as heating and cooling the building and heating the water are carried out by boilers working with solid fuel. Examples of some tools used for heating and cooling; We can provide appliances such as heaters, water heaters, air conditioners, combi boilers, radiators. Besides these:
The pipes laid on the floor carry the hot water and increase the heat rate of the floor. In this system, the temperature should not exceed 40 degrees. In floor heating systems, a mixing circuit is needed in order not to have excessively high temperatures. The user can create the underfloor heating system according to his wishes, but there are a few rules. These; Each room where the system to be installed must have a separate control system. The pipe to be used should not exceed 120 meters. The load ratings of the circuits should be equalized. It is quite free to use only if the warnings such as the pump should be determined by looking at the maximum head loss in the circuit.
The natural rays from the sun are captured and prepared for use by solar energy panels. Panels are generally installed on roofs. The number of panels varies according to the size of the area where it will be installed. Solar panel systems are water-based like underfloor heating systems. A circulation pump should be used in all water-based systems. In order to reduce the water density in the panel placed on the roof, glycol, which is an antifreeze agent, is added to the water. It is effective in heating the tap water we use in our daily life.
In the past, processes such as cooling and heating were very challenging as they were tried to be handled naturally. The natural ways could not reach a sufficient level, so people sought to establish alternative systems. Considering the working conditions today, it can be seen that the time we stay indoors is much longer than when we stay outdoors. Of course, this situation, which varies from person to person, is too real to be ignored in general. Indoor environments need heat or heat loss according to the season. There are also areas where the season does not matter and must be constantly cold. Like morgues, for example. Another place where the cooling system has to work continuously is drug stores. Medicines should be stored in cold environments so that they do not lose their usefulness. If we consider the food industry, we will see the same situation here. Foods need a cold environment to ensure their freshness and integrity. Heating systems are also used in areas such as greenhouses. The development of existing plants is supported and their growth is accelerated.
Some other areas where cooling systems are used: Cold storage rooms, chemistry laboratories, warehouses and artificial runways can be given as examples. Heating systems are used almost everywhere imaginable. It is used in areas such as hospitals, schools, hotels, factories, shopping malls, mosques, gyms, greenhouses.
