A heat pump is an electrically-ponered refrigerationcycle device which is capable ofproviding both heating and cooling to a residence. In the sumrrcr, it operates like an air conditioner by "moving" heat from inside the house to the outside. In the winter, the refrigerant flow is reversed, "moving" heat into the house by further chilling the already cold outside air and transferring the heat ga...

Effect of nanosilver (NS) on the heat-transferring rate to the core section of medium density fiberboard (MDF) mat was studied here. A 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 mL/kg, based on the weight of dry wood fibers; the results were then compared with the control MDF panels. The size range of nanosilver was 30-80 nm. Results showed t...

The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained. The temperature distributions along certain parts of the plate, which was subjected to heat generation and constant thermal conductivity condit...

This paper shows the research work on heat exchanger using nano fluid. In this paper we are using compact heat exchanger as heat transferring device while Al2O3 as a nano fluid. The effect of the nano fluids on compact heat exchanger is analyzed by using ε –NTU rating numerical method on turbo-charged diesel engine of type TBD 232V-12 cross flow compact heat exchanger radiator with unmixed flui...

it is possible for the lessor to transfer the leasehold property to another party through sale or other contracts over the course of lease without enjoying profit. according to iranian civil code, article 498, transferring the object of lease even to the lessee himself does not contradict the lease contract. after the contract, the lease contract is still valid. in french law, transferring the ...

Abstract In diesem Beitrag werden zwei verschiedene additiv herstellbare Metallstrukturen hinsichtlich der Entropieproduktionszahl bewertet. Die beiden Strukturen bei Temperaturniveaus, 200/80 °C und 700/580 °C, untersucht. Bei dem niedrigen Temperaturniveau ist insbesondere die Wärmeleitung innerhalb Struktur Haupttreiber für Entropieproduktion. Werden Temperaturen angehoben, so steigt gesamte...
