2results about How to "Precision cooling" patented technology

The utility model discloses a kind of double-motor screw vacuum pumps of built-in cooling of rotor, it is related to screw vacuum pump technical field, including fixed seat, the fixed seat top is equipped with chute, its bottom is installed cooling liquid circulation tank;The middle part of the chute is fixedly installed fixed frame, the both ends of chute are slidably installed sliding seat, the top of two sliding seats is fixed motor shell assembly, and rotor shaft is rotatably installed in motor shell assembly inside.The utility model described a kind of double-motor screw vacuum pumps of built-in cooling of rotor, and the cooling of efficiency rotor is cooled: cooling liquid directly flows through rotor shaft and spiral blade connecting port, realizes the accurate cooling to high temperature area, reduces the deformation caused by thermal stress, prolongs rotor life, and the linkage design of hydraulic cylinder and sliding seat can real-time adjustment rotor axial position, offsets thermal expansion in operation or assembly error, reduces wear risk, and the rubber pipeline soft connection of intercommunication mechanism adapts to the slight vibration when rotor rotates, and metal connecting fastener guarantees the sealing of high-pressure cooling liquid.

This invention discloses an intelligent control system for the gradient deployment of cooling tower fans under dynamic greenhouse demand. The system includes a multi-source data acquisition unit for collecting operational data from the greenhouse side and the cooling loop side. The operational data includes greenhouse internal temperature, greenhouse internal humidity, leaf surface temperature, light intensity, supplemental lighting equipment operation status, spraying or atomization status, ventilation execution status, circulating water flow rate, return water temperature, and environmental meteorological parameters. This invention relates to the field of greenhouse environmental control technology. This intelligent control system for the gradient deployment of cooling tower fans under dynamic greenhouse demand dynamically calculates the greenhouse's heat and humidity load requirements based on environmental data and a load propagation chain model. This ensures that the cooling tower system can flexibly adjust fan deployment according to changes in demand, thereby achieving precise cooling. Through fan candidate screening, benefit-cost calculation, and marginal net benefit analysis, the system can intelligently select the most suitable fan for deployment, avoiding energy waste.
