High efficiency air conditioner condenser fan

InactiveUS20050281672A1Save energyDependable electric load reductionPropellersPump componentsPower savingAerospace engineering
Novel twisted blades with an air foil for use with air conditioner condensers and heat pumps that provide improved airflow efficiency to minimize operating power requirements having an overall diameter across the blades being approximately 19 inches, and approximately 27.6 inches. The blades (AC-A) can run at approximately 840 rpm to produce approximately 2200 cfm of air flow using approximately 110 Watts of power from an 8-pole motor. Using an OEM 6-pole ⅛ hp motor produced approximately 2800 cfm with approximately 144 Watts of power while running the blades at approximately 1100 rpm. Power savings were 25% (50 W) over the conventional configuration. A second version of the fan (AC-B) with some refinements to the flow geometry produced a similar air flow while using only 131 W of power at 1100 rpm. Power savings were 32% (62 W) over the conventional configuration. Embodiments can include two, three, four and five blades equally spaced apart from one another about hubs. Additionally, a novel noise reduction configuration can include asymmetrically mounted blades such as five blades asymmetrically mounted about the hub. Short, conical diffusers were shown to further improve air moving performance by up to 18% at no increase in power. Embodiments coupled with electronically commutated motors (ECMs) showed additional reductions to condenser fan power of approximately 20%.

Hydraulic electricity generation shock absorber of vehicle

The invention discloses a hydraulic electricity generation shock absorber of a vehicle, belonging to the technical field of vehicle suspension systems and hydraulic transmission. The hydraulic power generation shock absorber of the vehicle generates electricity by utilizing pressure generated by hydraulic oil during shock absorption and comprises a piston shock absorption part, a valve path part and an electricity generation part, wherein the piston shock absorption part comprises a hydraulic cylinder (1) and a piston (2); the electricity generation part comprises a hydraulic motor (13) and an electric generator (16); and the piston (2) is pushed to move up and down in the hydraulic cylinder (1) during the shock absorption of the vehicle so that the hydraulic oil inside the hydraulic cylinder (1) is extruded out of the outlet of an upper cavity or a lower cavity of the hydraulic cylinder (1) and passes through the valve path part and then pushes the hydraulic motor (13) to drive the electric generator (16) to generate the electricity. The invention makes the hydraulic shock absorber of the vehicle possible have both stable shock absorption and electricity generation performance by adopting a reliable and mature hydraulic transmission technology and also provides a new research direction for the developed hydraulic shock absorber.

Medical micropore atomization medicine absorber

The invention relates to a medicine absorber, in particular to a medical micropore atomization medicine absorber. The medical micropore medicine absorber comprises a main body, the main body is provided with a medicine water box and a circuit device, the medicine water box is internally provided with a micropore piezoelectric ceramic atomization slice, the micropore piezoelectric ceramic atomization slice is connected with atomization control board in the circuit device, and the micropore piezoelectric ceramic atomization slice generates high frequency oscillation action under the control of the atomization control board, so that medicine water connected with the micropore piezoelectric ceramic atomization slice is absorbed by patients after the medicine water is vibrated out from the micropore on the micropore piezoelectric ceramic atomization slice to form fog. The invention can atomize the medicine water into fog with particle diameter in certain range and cause the fog to be absorbed by capillary of the breathing system via choke, trachea, bronchus and lung and then enter the blood circulatory system. The invention is mainly used for critical patients, comatose people and infant as well as patients unwilling to accept and unable to continuously accept drug administration in oral intake, injection and drop ways.

Control method of electronic cigarette and electronic cigarette

PendingCN109330032ARapid temperature controlSave energyTobacco devicesBattery energyElectronic cigarette
The invention relates to a control method of an electronic cigarette and the electronic cigarette. The control method of the electronic cigarette includes the following steps that S1, the resistance value of a heating body when a start unit of the electronic cigarette is triggered for the first time is acquired through a resistance value detection unit, and the resistance value is stored as the initial resistance value of the heating body; S2, the target temperature of the heating body is acquired, and the target resistance value of the heating body is acquired according to the initial resistance value; S3, the first real-time resistance value corresponding to first preset time after the start unit is triggered every time is acquired, the resistance value change of the heating body withinthe first preset time is calculated, and whether the resistance value change is larger than a first preset value or not is determined; if yes, the input power of the heating body is switched off, andif not, S4 is executed; S4, the real-time resistance value of the heating body is acquired through the resistance value detection unit according to a preset rule, and then the input power of the heating body is controlled to enable the real-time resistance value of the heating body to be the target resistance value. Temperature control over the electronic cigarette can be rapidly carried out underthe condition that battery energy is saved, and meanwhile anti-dry-burning heating is achieved.
