Abstract

The invention provides a multi-environment independent control method for ultra-high precision laboratories. The multi-environment independent control method comprises the steps that the states of air feeders are obtained; if the air feeders are started, exhaust fans are started; when the exhaust fans are in the working state, first pressure values collected by environment pressure sensors in the laboratories are obtained, and if the first pressure values exceed the allowable range, exhaust electric valves of the laboratories are adjusted; and the switch states of air supplement valves in the multiple laboratories are obtained, if the switch states of the air supplement valves are open, air conditioning systems are started, and variable air volume adjusting valves on air supply channels and electric adjusting valves on exhaust pipes of the laboratories are opened in an interlocking manner. The invention further relates to a multi-environment independent control system of the ultra-high precision laboratories. According to the multi-environment independent control method and system of the ultra-high precision laboratories, the relative humidity of a room is controlled by controlling the absolute humidity of air, the humidity and temperature are independently controlled in a supernormal mode, and the cleanliness and the temperature and humidity precision are guaranteed under the condition that the air volume changes.

Description

technical field

[0001] The invention belongs to the technical field of clean laboratories, and in particular relates to a multi-environment independent control method and system for an ultra-high-precision laboratory. Background technique

[0002] The development of science and technology is closely related to the construction of laboratories and the level of scientific research facilities. The level of a national laboratory reflects the top level of science and technology of a country to a certain extent.

[0003] Temperature and humidity are an important indicator of the environment in the laboratory, and precise adjustment and control have always been the methods of research and development in this field. Domestic temperature and humidity control still only uses indoor real-time temperature and humidity information as the basis of control, ignoring all possible impacts of the external environment on temperature and humidity control.

[0004] Facing the high requirements ...
