Abstract Solar water heating systems have been widely used around the world. However, exposure to sunlight can overheat device, affecting efficiency and durability of system. This article proposes an adaptive deck controller that protects system from overheating without compromising availability domestic hot water. heaters are considered one most effective ways reduce a home’s carbon footprint....

In this work, a method for the characterization of plate heat exchanger working as evaporator is presented. It based on one-dimensional discretization exchanger, which solves transfer balance equations by means an iterative methodology area converging method. The inputs are flow rates fluids, inlet enthalpy refrigerant, superheating, and temperature pressure secondary fluid. Once refrigerant as...

The maintenance of most mosquito species in the laboratory requires periodic feedingof blooc to females. The expense and inconvenience of maintaining laboratory animals for this purpose has led to the development of methods fbr feeding preserved blood through various natural and artificial membrane materials (Tarshis 19b8. Bailey et al. 1978, Wirtz and Rutledge 19g0. Savage et al. 1980, Thomas ...

This paper proposes and analyses a new demand response technique for renewable energy regulation using smart hot water heaters that forecast water consumption at an individual dwelling level. Distributed thermal energy storage has many advantages, including high overall efficiency, use of existing infrastructure and a distributed nature. In addition, the use of a smart thermostatic controller e...

The analysis of water quality, regarding the content of metals, especially heavy and radioactive ones, has been carried out in an indirect way, by testing scale formed in a hot-water heater, using water from the water-supply network of the city of Belgrade - the district of New Belgrade. The determination of the composition and the structure of the scale has resulted in its complete identificat...
