It is obvious that the basic principle of operation for a heat pump is the same as that of a refrigeration device except that for a heat pump attention is focused on the heat delivered by the device rather than the heat picked up at the evaporator. Definitions of the coefficients of ...
First, based on a generic schematic representation of a magnetocaloric heat pump, or refrigerator, various problems and challenges found in the current state of the art are pointed out and discussed. Second, different design principles for magnetic heat pumps are examined. As a means to improving...

Very High Temperature Heat Pump 1. Introduction Heat pumps (HP) are used for a variety of different applications. In the industrial sector, most of the installations use waste heat to supply domestic hot water and space heating [1]. In Germany, HPs with supply temperatures of 100 °C can ...
The compressor is stopped, and a low-power refrigerant pump is used for forced convection circulation of refrigerant. In this way, the indoor evaporator provides cooling and the outdoor condenser dissipates heat continuously. This mode ensures the cooling capacity equal to that of the compressor, ...
To probe this, we used isogenic strains of E. coli with altered activities of the AcrAB-TolC efflux system. We found that changing efflux pump activity reduced bacterial susceptibility to a range of antibiotics, including DT non-permeabilizers and SCH79797. However, it did not affect ...

The number of connection ports for each element is determined by the number of energy flows it exchanges with other elements in the system, and depends on the level of idealization. For example, a fixed-displacement hydraulic pump in its simplest form can be represented as a two-port element...
