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.
These are solid-state devices and unlike dynamos have no moving parts, with the occasional exception of a fan or pump to improve heat transfer. If the hot region is around 1273K and the ZT values of 3 - 4 are implemented, the efficiency is approximately 33-37%; allowing TEG's to compete with certain heat engine efficiencies.
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.
It is based on market capitalisation. Weighting of shares is conducted in proportion to the issued ordinary capital of the listed companies, valued at current market price (i.e. market capitalisation). The base year is 1985, and the base value of the index is 100. This is the longest and the broadest measure of the Sri Lankan Stock market.
Thermal power stations in Sri Lanka now roughly match the installed hydroelectric generation capacity, with a share of nearly 49% of the available capacity in December 2013 and 40% of power generated in 2013. [9] Thermal power stations in Sri Lanka runs on diesel, other fuel oils, naptha or coal. [9]
It will use 500 metric tons (1,100,000 lb) of waste, with the generated power sold to the state-owned Ceylon Electricity Board at a rate of Rs. 37.10 per KWh generated. The residual bottom ash from the process will be used for road construction and other uses, while the unusable fly ash (amounting to 2%) will be disposed of at predesignated ...
The company controls the subsidiaries of Singer Finance (Lanka), Singer Industries (Ceylon), Regnis Lanka, Realty (Lanka) Ltd, Singer Digital Media (Pvt) Ltd, and Singer Business School (Pvt) Ltd. [1] Singer (Sri Lanka) was credit rated as A+(lka) by Fitch Ratings in April 2022. [7] The company have chosen IFS AB's software as their ERP system. [8]
