P. Govt and the increasing demand from private market, the promoters have contemplated the proposed expansion project with increased capacity of 10,000 pumps and 8000 control panels. The project ...

The pump suction pipe may be earthed and used as one side of the control circuit, the pressure of which (25 v.) is derived from a small double-wound transformer supplied from the power or lighting ...

However, the usually bulky and hard-to-carry pneumatic actuation systems restrict the portability, and the air pumps provide constant flow rate which constrained the applications such as soft wearable ...

The proposed technology offers the advantage of bypassing the need to control the compressor of the heat pump, which is a function that is commonly not available in commercial devices. Scientists ...

Scientists at the Pusan National University in South Korea have developed a control system for air-source heat pumps (ASHP) which they claim allows users to take complete control of their devices.
