What is a motorhome?
In response to the question of what is a motor house, it can be said that the motor house of a residential, office, commercial or industrial building is a room or space of a building that is used for the installation of equipment, installations and parts of the motor house (mechanical and electrical cooling and heating facilities). Is considered. The dimensions of the considered room or space are proportional to the dimensions and size of the desired building or industries. In buildings or small industries, usually one room on the lower floors is enough to install engine room equipment, but in large residential, office, commercial, industrial, etc. buildings, often several rooms or one or more floors of the building are considered for installing engine room components. is taken.
The most important components of the construction engine room and industrial engine room
The engine room components of buildings and industries are: 1. Equipment and facilities that generate hot and cold water 1. 1. Boilers or hot water boilers with gas burners (water heating devices) with an efficiency between 78 and 86% 1. 2 . Chillers (water cooling devices) 1. 3. A cooling tower installed in an open space such as a roof or yard (if using a cold water compression chiller or an absorption chiller)
Note: The air-cooled compression chiller does not need a cooling tower. In fact, the cooling tower is used only when the chiller is either a water-cooled compression type (as shown in the figure below) or an absorption type. Because when the chiller takes the heat of the water to cool it down, it has to somehow expel this excess heat to the outside environment. but in the cold water compression type or the absorption type, this excess heat is taken by the water and then this water is sent to the cooling tower (which is usually installed on the roof) so that this water heat is rejected to the outside environment. Therefore, if an air-cooled compression chiller is used in a building, there is no need to install the chiller in the engine room and it should be installed in an open space such as the roof, but if the desired chiller is a water-cooled compression or absorption type, it must be installed in the engine room facilities. and we will also need a cooling tower that will be installed on the roof
2 . Health spa creation equipment
Sanitary spa tanks (drinkable and for washing) including double wall tank or coiled tank The hot spring that is needed for drinking and washing in the building is created in a source called the sanitary hot spring source, which is made in double-walled or coil types. In this way, a part of the hot water or hot steam coming out of the boiler is sent to the source of the health spa with a pump and piping, and at the same time, a municipal water line also enters this source from the other side and they exchange heat together until the temperature Health spa to increase. Then this water is pumped with pipes and pumps throughout the building for daily consumption.
3. Additional equipment and facilities
4. Cold and hot water transfer facilities to the building
5. Cold and hot air distribution devices in the building
Using equipment such as fan coils, heaters (radiators), air conditioners, etc. to distribute hot and cold air inside the building (as a result of the heat exchange of hot and cold water with air in these equipments) or sending cold water to industrial equipment For cooling the equipment in the engine room of the factories The picture below shows a simple example of the most important components of the engine room of the building including chiller, boiler, sanitary spa source and fan coils on each floor for ventilation (air cooling and heating)
6. Pool water purification equipment
Considering the swimming pool (and next to it the sauna and jacuzzi), equipment for purifying the pool water should be considered separately. Also, hot and cold water for hot and cold water pools should be provided by separate boilers and chillers. The water purification system includes a variety of filters that are determined according to the water quality of the area.
How does the engine work?
In response to the question of how the engine room works, in general, it can be said that water-cooled compression chiller devices or absorption chillers located in it (or air-cooled compression chillers located on the roof), water temperature Reduce the input to the device and the boiler devices or hot water or hot steam boilers equipped with gas burners increase the temperature of the water input to the device. The way the engine room works is that the water pumps send this hot and cold water through the central piping and after passing through the water flow regulating valves, to different parts of the building for heating or cooling the air in the building (by heaters, fans). They send coils, air conditioners, underfloor heating systems, etc.) or cooling industrial equipment. At the same time, a separate piping is also used to send the health spa from the sources or the spa storage tanks to the entire building. The figure below shows an example of an air-cooled compression chiller and a boiler that send hot and cold water to the air conditioner installed on the roof so that the fan in the air conditioner blows air from around the pipes containing cold or hot water. Reduce or increase the air temperature (according to the season) and distribute it with ducting in the entire building, hall or shed.
