Temperature control is an important task in the modern industries like chemical, pharmaceutical etc. considering the real time variations in their plants. The present work gives experimental results for the control of a constant level stirred nonlinear temperature water bath under continuous inlet and outlet flow. A real time PID controller taken with a fixed bias voltage has been used and tune...

District heating systems are gaining global recognition as an essential tool for reducing greenhouse gas emissions and transitioning to a low-carbon-energy future. In this context, heat pumps becoming important technology, providing effective solution improving energy efficiency the reliance on fossil fuels in systems. Therefore, study is focused optimal selection of pump different types buildi...

BACKGROUND Several studies have shown adverse effects of gas cookers and heaters on respiratory health. The long term effects of early life exposure to these appliances are not known. This study investigated the effect of exposure to fume emitting heaters, currently and during the first year of life, on the risk of asthma outcomes. METHODS A cross sectional study of schoolchildren (n = 627) a...

Consumers are always influenced by external information before making decisions to purchase energy-saving electric appliances. However, the effects of different sources overlooked previous studies. As a kind green and safe appliance, Heat Pump Water Heater (HPWH) is expected be popular in Chinese market. This study, based on an investigation eastern China, will reveal attitudes potential consum...
