Description
Technical Field
The invention relates to the technical field of energy control, in particular to a clean room electric energy control system.
Background
The energy consumption occupies a large proportion of the production cost. With the development of the scientific and technological level, the demand of the clean room is rapidly increased, and higher requirements are put forward on the energy conservation of the clean room, and in the electric energy consumption of the clean room, the energy consumption mainly comprises an air purification system, a lighting facility, a fire-fighting facility and the like, wherein the energy consumption of the air purification system accounts for about 50% of the total energy consumption, and the lighting facility is the second time. The air conditioning load comprises a fresh air cooling and heating load, an equipment and lighting cooling load, a personnel cooling and heating load, an enclosure cooling and heating load and an air infiltration cooling and heating load. Therefore, the energy consumption of the air purification system of the clean room is necessarily related to the equipment and the lighting facilities, so how to reasonably control the electric energy of the air purification system, the lighting facilities and the fire-fighting facilities is a problem which needs to be solved urgently at present.
In order to achieve the purpose of saving energy, the traditional treatment mode is considered from the aspects of energy consumed by fresh air heat and wet treatment, energy consumed by temperature rise of a fan in a system and energy consumed by operation of process equipment, and the traditional treatment mode has the measures of reducing the air supply quantity of the system, changing the temperature and humidity base number required by a clean room, reducing the exhaust air quantity, properly reducing the static pressure value in the clean room, adopting a low-resistance air filter, adopting a standby fan to operate in non-working time, closing a sending fan and a return fan in the system, saving energy in a purification air conditioning system provided with a circulating fan, reducing the energy consumed by the temperature rise of the fan and a motor as much as possible, and reducing the air leakage quantity of the air conditioning system and an air conditioner.
The traditional control modes are mainly divided into the following modes: controlling a multi-gear switch; continuous speed regulation control; computer control and remote control.

Although the traditional technology can achieve the purpose of reducing consumption, the technology aims at sacrificing the technical indexes of the clean room, which is a measure for treating symptoms and not treating the root causes, and does not achieve the purpose of energy conservation and emission reduction in a real sense.
