Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

Heat transfer is a discipline of thermal engineering that concerns the generation‚ use‚ conversion‚ and exchange of thermal energy and heat between physical systems. Heat transfer is classified into various mechanisms‚ such as thermal conduction‚ thermal convection‚ thermal radiation‚ and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species‚ either cold or hot‚ to achieve heat transfer. While these mechanisms have distinct characteristics

heat exchanger is a device built for efficient heat transfer from one medium to another. The media may be separated by a solid wall‚ so that they never mix‚ or they may be in direct contact.[1] They are widely used in space heating‚ refrigeration‚ air conditioning‚ power plants‚ chemical plants‚ petrochemical plants‚ petroleum refineries‚ natural gas processing‚ and sewage treatment. One common example of a heat exchanger is the radiator in a car‚ in which the heat source‚ being a hot engine-cooling

abnormal and hence undesirable - not because it is immoral or sinful‚ or because it weakens society or hampers evolutionary development‚ but for a purely mechanical reason. It is a misuse of bodily parts. Clear empirical sense attaches to the idea of the use of such bodily parts as genitals‚ the idea that they are for something‚ and consequently to the idea of their misuse. I argue on grounds involving natural selection that misuse of bodily parts can with high probability be connected to unhappiness. I
