A Heating, Ventilating, and Air-Conditioning (HVAC) Control system operates the mechanical equipment (boilers, chillers, pumps, fans, etc.) to maintain the proper environment in a cost-effective manner. A proper environment is described with four variables: temperature, humidity, pressure and ventilation.
Temperature, The comfort zone for temperature is between (20°C) and (25°C). Temperatures less than (20°C) may cause some people to feel too cool. Temperatures greater than (25°C) may cause some people to feel too warm. Of course, these values vary between people, regions and countries.
Humidity should be comfortable, small relative humidity causes the room to be too dry, which has an adverse effect on health, computers, printers, and many other areas. Large relative humidity causes the room to be muggy and increases the likelihood of mildew problems. In fact, proper humidity in Palestine is about 50%.
Pressure, The rooms and buildings typically have a slightly positive pressure to reduce outside air infiltration. This helps in keeping the building clean.
Ventilation, Rooms typically have several complete air changes per hour. Indoor Air Quality (IAQ) is an important issue. The distribution pattern of the air entering room must keep people comfortable without feeling any air stream.
. This project will include the fire-fighting system that will be designed to keep the building safe from fire accident. Additionally, the water system and plumbing such as a network of hot and cold water. This service can be achieved through the identification of the correct size for pipes.
