Smart Heat heating system Types of central heating systems
1. Hot Water Heating System: Water is used in this system as a medium for heat transfer. It is heated in Boilers in particular. It is then rotated in a pipe network by circulating pumps and then distributed to Heat exchangers and heat exchangers are then transferred to the space air (according to the principle of radiation). This system is the most common in heating homes, schools, hospitals and hotels. Advantages include:
1. Low cost of construction and operation compared to other systems.
2. Provides good health conditions.
3. Ease of maintenance work.
2. Hot Air Heating System: Air uses this system as a medium to transfer heat, and heats (air) in different ways in independent central or external heating units, and then drives in special corridors called air ducts, where they exit from the end The corridor to the space to be warmed.
3. Steam Heating System: Steam is used in this system as a medium for heat transfer, where steam is generated in steam boilers of different pressures, the water turns into steam. The idea of the central heating system: The water is heated by the boiler by burning the diesel. The hot water rises to the top, which is less dense with heating in the pipes with the aid of a water pump until it reaches the thermal radiators in the walls of the house. Thermostat controls and adjusts the temperature so that if the temperature exceeds the desired limit, the thermostat is powered by the device and vice versa. Analysis of central heating system: Inputs: Connecting pipes, pump, diesel, electricity, water, boiler, heat radiators. Processes: Diesel combustion to raise the water temperature by the boiler, separating or connecting the pump. Outputs: Heat for heating. Feedback: thermostat. Control: Increase or decrease the rate of diesel combustion, separating or connecting the pump based on thermostat. Boiler definition: A device or room in which diesel is heated to raise the water temperature. Definition of thermostat: It is a metal band in a sense consisting of two different metals. Thermostat mechanism: When the device is turned on and the circuit is closed, a stream passes through the bimetal tape. After a while the film is heated because one of the tubes is stretched in a different way.
