Abstract Psocids are damaging stored-product pests. In this study, eggs and early-instar nymphs, adults, all life stages of Liposcelis entomophila, L. decolor, bostrychophila, paeta were subjected to 43, 50, or 75% (Control) relative humidity (RH) for 2, 4, 6, 8, 10, 12, 14, 16 d at 30.0°C. All adults these species died within 8 both 43 50% RH, except which required 12 RH 100% mortality occur. ...

Abstract We propose the use of green hydrogen as a fuel for seawater heater in humidification / dehumidification (HDH) desalination plant to increase its productivity, allow scaling large dimensions without negative environmental effects, and guarantee continuous operation. develop mathematical model proposed HDH configuration. For operating conditions that very low NOX production, consumption ...

The recent rapid development of underground utility tunnels (UUT) in China reflects the government’s resolve to improve municipal service amid urbanization. Although safety is primary concern design and operation UUT, moisture issue appears be neglected. In southern eastern China, however, condensation UUT noted believed responsible for high rate equipment failure deterioration air quality insi...

this paper describes the theoretical and experimental investigations of the key components and also the performance analysis of a rotary wheel for using as a solid desiccant dehumidifier and also indirect evaporator cooling system. solid desiccants have long been used in dehumidification and cooling systems for energy efficiency or reduce electricity. although many mathematical models on the ro...

A direct expansion (DX) HVAC system is an efficient way to supply fresh and dehumidified air to a built environment. To improve the efficiency of a conventional DX system in hot and humid regions, fresh air dehumidification and conditioning systems with energy recovery measures are the key equipment to reach such a goal. To achieve this goal an integrated system is proposed. The integrated syst...

Abstract: In recent years, the fixed bed dehumidification system has received extensive attention. Research shows that can be combined with vapor compression refrigeration to replace traditional air conditioning (A/C) system, improve efficiency of and reduce energy consumption A/C. this study, optimization improvement methods dehumidifier in years are introduced detail firstly. It points out ad...
