When deriving or determining the coefficient of performance, the first rule of thermodynamics is important to remember. This rule states that energy can be changed, but it cannot be destroyed nor can it be created. As a result of this rule, the equations used to determine the coefficient of ...

aThis paper describes the use of endoreversible thermodynamics to evaluate the behavior of a mechanical compression refrigeration system. The coefficients of performance of the endoreversible Carnot Cycle, COPCE, were obtained by including the external irreversibility associated with heat transfer. The rea...
A heat pump with a COP of 2.8 is used to heat an air-tight house. When running, the heat pump consumes 5 kW of power. If the temperature in the house is 7 degrees C when the heat pump is turned on, ho What is the specific heat of ice J/(kg C)?
It’s against thermodynamics laws. Heat should flow from hot regions to cold regions. In this regard, the "uphill" heat transfer against heat laws requires work. COP, therefore, shows how effectively an air to water heat pump does this work. It states the power quantity needed by the unit...

What Is A Heat Pump? (Heating + Cooling – Explained)Heat or kinetic energy always wants to move from an area of high kinetic energy to an area of low kinetic energy. The heat of kinetic energy is always looking to dissipate. The Second Law of Thermodynamics governs the way in which ...
This mirrors the first law of thermodynamics which states that energy can transform from one state to another, but it can neither be created nor destroyed. The same can be said for your soul, as your soul is energy: the life force energy. Therefore, it can never die, only change form...
Ours is an itinerant workshop of narrative assemblages and repairs, thermodynamics of the imagination, collective writing and narrative detoxification. From this workshop, other collectives of writers have continually sprung up:Kai Zen,MetalMente,Joana Karda,Moira Dal Sitoand others. ...
Metallacarboranes are 3-dimensional cluster compounds that in general can exist in a number of isomeric forms which cannot always be distinguished spectroscopically, in which case crystallographic study is the essential experimental technique [4]. A good example concerns the icosahedral metallacarborane...
