This paper presents experimental investigations of the dynamics of a transcritical CO2 heat pump system with two thermal storages for simultaneous cooling and heating application. The preliminary results of the thermal battery are provided using a small-scale test bed that shows the accelerated penetration of renewable energy sources for building heating and cooling applications. The experiment...

BACKGROUND Invasive Mycobacterium chimaera infections were diagnosed in 2012 in 2 heart surgery patients on extracorporeal circulation. We launched an outbreak investigation to identify the source and extent of the potential outbreak and to implement preventive measures. METHODS We collected water samples from operating theaters, intensive care units, and wards, including air samples from ope...

Informal exchanges in workplace settings often occur at communal artifacts that encourage self-motivated interaction in a community. This phenomenon, the water cooler effect, is the resulting combination of the “space” augmented by the communal artifact and the “place” influenced by the activity that occurs here (Harrison & Dourish, 1996). We claim that the types of interactions that occur at a...

ARTICLE INFO a The temperature of earth is increasing drastically in the past few years due to which water temperature is also increasing. Water cooler is a device used to cool the temperature of water so that it is suitable for drinking purpose. This system works on the principle of vapour compression refrigeration system. CFC 22 is currently used in the system, but because of its high GWP and...

We have investigated electronic cooling of suspended nanowires with SINIS tunnel junction coolers. The suspended samples consist of a free standing nanowire suspended by four narrow (∼ 200 nm) bridges. We have compared two different cooler designs for cooling the suspended nanowire. We demonstrate that cooling of the nanowire is possible with a proper SINIS cooler design.

To test whether baboons are capable of implementing selective brain cooling, we measured, every 5 min, the temperature in their hypothalamus, carotid arterial bloodstream, and abdominal cavity. The baboons were unrestrained and exposed to 22 degrees C for 7 days and then to a cyclic environment with 15 degrees C at night and 35 degrees C during the day for a further 7 days. During the latter 7 ...

Abstract A finite time thermodynamic model of the multistage thermoelectric cooler with constant temperature heat source and water-cooled is established, calculation method input power coefficient performance (COP) are given. The influence key parameters on device under different working conditions effects current cross-sectional area unit refrigerating capacity, COP, perfection, module utiliza...

An extensive 2013 mass mortality event along the West Coast of North America due to Sea Star Wasting Disease (SSWD) has affected at least 20 species of sea stars. Among environmental factors potentially contributing to the timing of the current outbreak, increased coastal water temperatures are hypothesized to have contributed to previous and current outbreaks of SSWD. With a laboratory experim...

Electronic equipment allows fishes, by their spatial movements, to regulate the temperature in experimental tanks. Swimming into warmer water causes the temperature of the entire tank to increase; conversely, swimming into cooler water causes the temperature to decrease. The technique may be adapted for studying simultaneous behavioral regulation of temperature and nonthermal factors.
