Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
An air source heat pump (ASHP) is a heat pump that can absorb heat from air outside a building and release it inside; it uses the same vapor-compression refrigeration process and much the same equipment as an air conditioner, but in the opposite direction. ASHPs are the most common type of heat pump and, usually being smaller, tend to be used ...
A Johnson thermoelectric energy converter or JTEC is a type of solid-state heat engine that uses the electrochemical oxidation and reduction of hydrogen in a two-cell, thermal cycle that approximates the Ericsson cycle. [1] It is under investigation as a viable alternative to conventional thermoelectric conversion.
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
The launch of the Viceroy Special was spearheaded by Hemasiri Fernando and Cliff Jones. [3] The idea of re-introducing steam to Sri Lanka rails was inspired by a tourism promotional visit to Sri Lanka in 1984 by Cliff Jones who, returning from a day trip to Kandy, called at Dematagoda loco sheds and saw, what he later described a graveyard of 'veritable massive tourism potential' and put the ...
In 2020, Singer (Sri Lanka) emerged as the market-leading seller for Dell laptops in Sri Lanka. [9] Due to the COVID-19 pandemic , increased incidences of remote work and distance education arrangements, the demand for consumer electronics rose and the company posted LKR16.7 billion in sales in the second quarter of 2020.

The proposed connection involves the linking of the national grids of India and Sri Lanka via Rameshwaram in south India and Talaimannar in north-west Sri Lanka. The project involves the construction of a HVDC connection between Madurai in southern India and Anuradhapura in central Sri Lanka, through the Palk Strait. The link would measure ...
The Kandy Airport is a proposed domestic airport in the central city of Kandy in Kundasale, Sri Lanka, aimed at facilitating growth in the influx of tourists to the Central Province. Domestic operations from Bandaranaike International Airport in Colombo are set begin with the new domestic carrier Cinnamon Air. [1]
