Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
Specifically, the heat pump transfers thermal energy using a heat pump and refrigeration cycle, cooling the cool space and warming the warm space. [1] In winter a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in summer.
A Lennox air conditioner. Lennox International Inc., headquartered in Richardson, Texas and organized in Delaware, is a provider of climate control products for the heating, ventilation, and air conditioning (HVAC) and refrigeration markets. [1]
The most efficient ground source heat pumps use ACR, Type L or special-size copper tubing buried into the ground to transfer heat to or from the conditioned space. Flexible copper tube (typically 1/4-inch to 5/8-inch) can be buried in deep vertical holes, horizontally in a relatively shallow grid pattern, in a vertical fence-like arrangement in ...
General Sir John Philip Du Cane, GCB (5 May 1865 – 5 April 1947) was a British Army officer. He held high rank during the First World War, most notably as Major General Royal Artillery at General Headquarters in 1915 when the British Expeditionary Force (BEF) was expanding rapidly, as General Officer Commanding XV Corps 1916–18, then from April 1918 as liaison officer between Field Marshal ...
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...
In the heat engine model with two thermal reservoirs (hot and cold reservoirs), the limit of the efficiency of any heat engine =, where and are work done by the heat engine and heat transferred from the hot thermal reservoir to the engine, respectively, can be derived by the first law of thermodynamics (i.e., the law of conservation of energy ...
Daniel Duchaine (1952 – January 12, 2000) was an American bodybuilder.Nicknamed the steroid guru, Duchaine gained worldwide notoriety due to his outspoken opinions on the use of performance-enhancing drugs, and made numerous television appearances discussing the subject on shows such as 20/20, Geraldo, and 60 Minutes.
