RENEWABLE SOURCES-ENERGY EFFICIENCY

Heat pumps are devices with the help of which heat energy is transferred from one environment to another. Heat pumps enable the transfer of heat energy from a lower temperature level system (earth, water, air) to a higher heat level system (central heating or hot water preparation) using additional operating energy (electricity for the compressor) by means of a suitable working medium (freon) . (Heat Pumps: Operation, Installation, Service) Unlike other renewable energy sources such as solar and wind energy, ambient heat (earth, water, air) is available for continuous use throughout the year. With a heat pump, without an additional energy source, it is possible to cover all the thermal energy needs of a house for heating and hot water preparation. HOW THE HEAT PUMP WORKS The principle of operation of the heat pump is simple, you could compare it with a household refrigerator only in the reverse function: it heats instead of cooling. Ambient energy (earth, water, air) is transfe...

Today, LED lighting takes precedence over classic energy-saving light bulbs, as well as incandescent light bulbs, but there are still a number of doubts that have arisen from their objective differences compared to old light bulbs. About LED lighting The abbreviation LED stands for "light emitting diode", which is a semiconductor element that transmits current in only one direction and illuminates with electricity. LEDs convert most of the energy into light and therefore consume significantly less energy for lighting. With classic incandescent bulbs, energy is converted into heat, and the incandescent bulb emits light and therefore they consume as much as 80% more energy than LED lighting. LED technology was very quickly recognized as a real revolution in the field of lighting and that is why it has become the standard today. (LED Light Bulbs 60W Equivalent)   It is also used in the car industry. Due to a number of advantages over previous forms of lighting, LED lightin...

Smart plugs are the first easy step into home automation.  (Residential Wiring and Smart Home Technology) Smart home technology is becoming more and more popular day by day, and a large number of brands are slowly launching devices that can help you save time, power consumption, and even improve security inside the home. One of the hit products in this fast-growing sector is the so-called smart plug.   What is a smart plug?   It is a small plug that you plug into a standard socket and then simply plug your device into.  Figure 1- Smart plug You don't have to have anything but a router and a smartphone to install them - devices that can be found in more or less every household. With a smart plug, you take control of devices in the house by sending commands remotely. A cheaper smart plug costs about twenty dollars, and all devices also work with most home assistants like those from Amazon or Apple. The smart plug therefore plugs into a standard socket and c...
