A water cooler or water dispenser is a device that cools and dispenses water. Generally they are divided into two categories: water chillers without bottle and bottled water. Bottled water coolers are connected to a water supply, while bottled water coolers require delivery (or self-collection) of water in large bottles from vendors. The water cooler can also refer to a primitive device to keep the water cool. .
Water cooler effect
A water cooler effect is a phenomenon, which occurs when employees at a workplace gather around the office water cooler and chat. It is a synonym for gathering and connecting people in a certain environment (for example, the office). When a television program, such as a soap opera or a series, is spoken among many people (mostly related to guessing what will happen in the next episode) you can say that the program has a water cooler effect.
Solar air conditioning refers to any air conditioning system (cooling) that uses solar energy. This can be done through the conversion of passive solar energy, solar thermal and photovoltaic conversion (sunlight to electricity). The United States Energy Independence and Security Act of 2007 created funds from 2008 to 2012 for a new solar air conditioning research and development program, which should develop and demonstrate multiple technological innovations and economies of scale in mass production. Solar air conditioning could play an increasing role in designing buildings for zero energy and energy.
History
At the end of the 19th century, the most common liquid for absorption cooling was a solution of ammonia and water. Nowadays, the combination of lithium bromide and water is also in common use. One end of the expansion / condensing pipe system is heated, and the other end is cooled enough to make ice. Originally, natural gas was used as a source of heat in the late nineteenth century. Today, propane is used in recreational coolers for vehicle absorption coolers. Solar thermal collectors can also be used as the modern "free energy" heat source. A report sponsored by the National Aeronautics and Space Administration (NASA) in 1976 examined applications of the solar air conditioning system. The techniques discussed included solar energy (absorption cycle and heat engine / Rankine cycle) and related solar (heat pump) along with an extensive bibliography of related literature.
