【作者】 Michael J. Brezonick
【摘要】 Buffalo Turbine introduced the Cyclone KB23 tow-behind debris blower, which it said is ideal for municipal and government work. The Cyclone KB23 has a Briggs & Stratton Vanguard EFI gasoline engine rated 23 hp that runs a directdrive turbine. A 12-function wireless remote allows instant control of engine start/stop, throttle speed and 360-degree nozzle control. It also has auto nozzle positioning with six positive stops for quickly locating optimum blowing angles at a touch of a button, said the company. The new unit comes standard with an off-road trailer package and can also be skid mounted in a UTV or truck. A DOT trailer package for highway use is also available at additional cost.

【摘要】 Doosan Bobcat's industrial air compressor lineup now includes a 150-hp fixed-speed, oil-flooded, rotary screw air compressor. Introduced in August as the D150, it will become the IA150 in 2024 as part of the company's transition to rename and rebrand all Doosan Industrial Air products to align to the Bobcat brand and style. The D150 is rated 705 cfm at 125 psig with nominal power of 150 hp (1150 kW). It features a IE3 premium efficiency TEFC (totally enclosed, fan-cooled) motor that offers protection against outside contaminants, such as dust or moisture. Its 100,000 hour-rated airend features three bearings for improved reliability, maximized uptime and minimized downtime, according to the company.

【摘要】 The vapor-compression-based conventional split air conditioners (CACs) consume a large portion of total electrical power and pose an alarming threat to global environment. The present work aims to reduce cooling load and power consumption of CAC by employing a dew point evaporative cooler (DPEC). DPEC consists of a counter flow type heat and mass exchanger with alternate layers of dry and wet channels. The intake air is sensibly cooled before entering the cooling room through the evaporator coil of the air conditioner. Also, the working air (a part of outlet air in dry channel), after absorbing sensible heat of intake air and water vapors from the wet channel surface, is allowed to pass across the condenser coils. The intake dry-bulb temperature (T_0= 29-44℃) and specific humidity (ω_0=6-22 g/kg) are taken as input parameters. While the cooled air entering the evaporator decreases the cooling load on the conditioned space, the compression work is also reduced due to increased heat transfer in the condenser. The maximum reductions in cooling load and monthly energy consumption at T_0=44℃ and ω_0=6 g/kg are found as 59.54% and 340 kWh, respectively. The water consumption for different months of the cooling season varies from 1037.8 L to 2905.95 L. The average energy savings with the DPEC system for hot-dry climate (from April to June) and hot-humid climate (from July to September) of New Delhi, India, are observed to be 479.6 kWh and 79.1 kWh, respectively. The proposed system is found to payback in about 3.37 years.

【摘要】 We are developing a speed reducer that can be considered a transformation of a worm gear reducer: the worm is replaced by an inverted roller screw, and the gear is replaced by a threaded chain drive. This configuration lessens wear, increases load capacity, and improves efficiency. The threaded chain consists of nut-shaped links. This paper presents the results of tests carried out on a prototype with a reduction ratio of 46.
