• Subcooling
  • Being both similar and inverse processes, subcooling and superheating are important to determine stability and well-functioning of a refrigeration system. (wikipedia.org)
  • A huge portion of refrigeration systems use part of the condenser for subcooling which, though very effective and simple, may be considered a diminishing factor in the nominal condensing capacity. (wikipedia.org)
  • It is to be noted that superheating has exactly the inverse effect, and that an internal heat exchanger alone, is not able to increase the capacity of the system because the boosting effect of subcooling is dimmed by the superheating, making the net capacity gain equal to zero. (wikipedia.org)
  • Heating

  • widely
  • Adsorption is present in many natural, physical, biological and chemical systems and is widely used in industrial applications such as heterogeneous catalysts, activated charcoal, capturing and using waste heat to provide cold water for air conditioning and other process requirements (adsorption chillers), synthetic resins, increasing storage capacity of carbide-derived carbons and water purification. (wikipedia.org)
  • temperature
  • Furthermore, the uniformity of the underground temperature compared to the outdoor air translates into less stress on the systems. (wikipedia.org)
  • Superconducting Magnetic Energy Storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. (wikipedia.org)
  • cycle

  • The operating principle of the refrigeration cycle was described mathematically by Sadi Carnot in 1824 as a heat engine. (wikipedia.org)
  • When the working fluid is a gas that is compressed and expanded but does not change phase, the refrigeration cycle is called a gas cycle. (wikipedia.org)
  • Flash-gas must not be confused with lack of condensation, but special gear such as receivers, internal heat exchangers, insulation, and refrigeration cycle optimizers may improve condensation and avoid gas in the liquid lines. (wikipedia.org)
  • This may also be considered as flash-gas but normally doesn't produce complications in the refrigeration cycle. (wikipedia.org)
  • thermodynamic
  • For the improvement of the system, a detailed computational and thermodynamic analysis must be carried out. (hindawi.com)
  • The thermodynamic analyses of adsorption systems are complex because of the complex differential equations involved. (hindawi.com)
  • improperly
  • This is because R22 and mineral oil separate into two phases in the operating range which can cause return issues in improperly designed systems. (wikipedia.org)
  • energy
  • From this context, the adsorption refrigeration system attains a considerable attention in 1970s due to the energy crisis and ecological problems related to the use of CFCs and HFCs. (hindawi.com)
  • Recently some works about the use of ANN in energy systems have been published [ 10 - 17 ]. (hindawi.com)
  • The US Environmental Protection Agency (EPA) has called ground source heat pumps the most energy-efficient, environmentally clean and cost-effective space conditioning systems available. (wikipedia.org)
  • There is also increasing awareness of environmental and energy issues among urban and suburban residents with limited space in which to install a system. (wikipedia.org)
  • Due to the energy requirements of refrigeration and the high cost of superconducting wire, SMES is currently used for short duration energy storage. (wikipedia.org)
  • technicians
  • You`ll see those same technicians on expensive service calls installing factory replacement parts because components are not interchangeable with other brands or with different systems offered by the same manufacturer.Many chilled water systems employ chillers. (environmental-expert.com)
  • high
  • This simplicity allows the system to reach high efficiencies while using a shorter and smaller set of buried tubing, reducing footprint and installation cost. (wikipedia.org)
  • liquid
  • Flash-gas may be detected in the system by the observation of bubbles or gas presence in the liquid line, or the foamy aspect of the fluid. (wikipedia.org)
  • Efforts to prevent flash-gas in the liquid line include a cautious design of the cooling system and its piping, but also the incorporation of gear that might help solve this type of difficulty. (wikipedia.org)
