One of the fundamental considerations in space heating (SH) consists in the variability of heat loads over time as result of external conditions. This paper shows the novel way to adapt a variable-flow system provide space heating (SH) and domestic hot water (DHW) to multiple buildings with varying loads.

Cloaking of heat flux and temperature
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011Due to equal arc length in different coordinate system, we derive the scaling factor of rectangular Cartesian coordinates and curvilinear orthogonal coordinates; meanwhile, we also derive the equations of heat flux density (or heat flux, or thermal flux) and quantity of heat by means of the transformation relation of vectors in different coordinate ...

High-temperature heat capacity of Dy2Cu2O5
Physics of the Solid State, 2013The molar heat capacity of Sc2Cu2O5 has been determined at temperatures from 350 to 893 K using differential scanning calorimetry. The experimental Cp(T) data have been used to evaluate the thermodynamic functions of the double oxide.

Optimum Heat Rejection Temperatures for Spacecraft Heat Pumps
Journal of Spacecraft and Rockets, 1989Use of two heat rejection temperatures instead of one for a heat-driven heat pump is shown to reduce spacecraft waste heat radiator area and heat rejection system mass. The optimum high rejection temperature T1 is shown to be somewhat less than Kerrebrock's rule, three-fourths of the heat source temperature TH.

Synthetic heat at mild temperatures
Somatosensory & Motor Research, 2002"Synthetic heat", also known as the heat grill illusion, occurs when contact with spatially adjacent warm and cold stimuli produce a sensation of "heat". This phenomenon has been explained as a painful perception that occurs when warm stimulation inhibits cold-sensitive neurons in the spinothalamic tract (STT), which in turn unmasks activity in the ...

Temperature and Heat Load Distribution in Rotating Heat Pipes
AIAA Journal, 1978An analysis is proposed for predicting the condenser wall temperature profile showing the effect of functions such as concentration of noncondensable gases, type of working fluid, condenser wall material, and cooling medium. A prediction of the heat rejected ratio of a condenser operating with noncondensable gas present to one with pure vapor is given.

Whether a particular substance exists as a solid, a liquid or a gas at a given temperature and pressure depends upon the strength of the forces of attraction between its constituent atoms, ions or molecules. Thus, at atmospheric pressure and room temperature the van der Waals’ forces between the oxygen molecules in air are not strong enough to make ...

Induction heating at low temperatures
Electrical Engineering, 1935Inductively heating iron parts for drying coatings discloses interesting features which may be applied to other low temperature processes. The electrical design of the oven and circuits for induction heating at low temperatures are considered in this paper.

CHI '09 Extended Abstracts on Human Factors in Computing Systems, 2009
HCI has many challenges and internal debates (for example, where is our theory? What is the role of design in HCI? What is the relationship between research and practice? How do we make an impact?) that recur at the CHI conference and that students either ask themselves or find they are asked by others.
