Abstract:

The process of carbon transfer from the atmosphere to the ocean floor is determined by three different pumps in nature: a solubility pump, an organic pump and a carbonate pump. The latter two are of biological nature. Phytoplankton is a key mediator of organic and carbonate pumps. Depending on its structure, either an organic pump or a carbonate pump will dominate. The structure of the phytoplankton community is formed depending on the hydrophysical and hydrochemical conditions in the ocean. An important regulator of a biological carbon pump is the intensity of the processes in the carbon cycl

Abstract:

In order to reduce the dependence on fossil fuels in the residential sector, low-carbon-footprint technologies such as heat pumps should be used. To fully exploit solar-assisted heat pumps, an effective control strategy is required. This study employs a low-global-warming-potential (GWP) refrigerant for a water-to-water reversible heat pump, which is assisted by a thermal energy storage tank, photovoltaic (PV) installation, and battery storage system using a dedicated control strategy. The heat pump’s operation is validated against the experimental data. Simulations are carried out for three d

For these reasons, the UHV of soft X-ray beamlines is usually maintained by sputter ion pumps and non-evaporable getter (NEG) pumps. However, conventional sputter ion pumps and NEG pumps scarcely pump hydrocarbons. Recently, we developed oxygen-free Pd/Ti as a new NEG that can reduce hydrocarbons in UHV. During baking o

The increase in production and modernization of existing heat pumps are global trends in the development and implementation of heat pump technology. Application of refrigerant with zero potential ozone depletion relative to fluorinetrichloromethane and minimum values of global warming potentials relative to carbon dioxide is environmentally justified in pumps. Prospective are stage compression heat pump units and, also, consecutive and cascade schemes of inclusion which provide higher temperature of the heat carrier in the system of heat supply.

Abstract:

Recent data suggest that heat pumps, despite having the potential to cover over 90% of the global space and water heating demands, only provide less than 5% of global heating. Heat pumps, in general, and ground source heat pumps, specifically, offer significant potential for energy savings and carbon emissions reduction in buildings. The realization of these potential benefits, however, requires proper design, installation, and operation of the entire heat pump system.

Abstract:

The use of pumps in water distribution networks is very useful when there is a need for additional pressure head. However, the functioning of pumps can be influenced by the presence of private storage tanks in the network, which alters the way the users draw water due to their compensation ability. This condition is very common in areas affected by the historical scarcity of water resources or intermittent supply (Mediterranean Area, Arabian Peninsula, etc.). This paper studies the effects of private tanks on the performance of pumps in a network model, considering different retention times an
