The Allihn-condenser or bulb condenser is named after Felix Richard Allihn (1854–1915). [ 12 ] [ 13 ] [ 14 ] The Allihn-condenser consists of a long glass tube with a water jacket . A series of bulbs on the tube increases the surface area upon which the vapor constituents may condense.
A sodium acetate heating pad. When the sodium acetate solution crystallises, it becomes warm. A video showing a "heating pad" in action A video showing a "heating pad" with a thermal camera. A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling.
A typical evaporative, forced draft open-loop cooling tower rejecting heat from the condenser water loop of an industrial chiller unit Natural draft wet cooling hyperboloid towers at Didcot Power Station (UK) Forced draft wet cooling towers (height: 34 meters) and natural draft wet cooling tower (height: 122 meters) in Westphalia, Germany Natural draft wet cooling tower in Dresden (Germany)
A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in vapor-compression refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator and is intended to regulate the superheat of the refrigerant that flows out of the evaporator ...
In about 1950 a hyperbolic reinforced concrete cooling tower was built with a capacity of 2.5 million gallons per hour (3.15 m 3 /s), with cooling range of 15 °F (8.3 °C). [12] However, there were complaints that operation of the cooling tower let to problems with ice in cold weather as water vapour from the tower froze as fine particles.

But a reforming justice system is feeding addicts into an unreformed treatment system, one that still carries vestiges of inhumane practices — and prejudices — from more than half a century ago. John Peterson got hooked on heroin in the mid-1950s, soon after returning home to Los Angeles from a stint in the Army.
Any mechanical components that can rust or corrode need regular cleaning or replacement due to the environment of high moisture and potentially heavy mineral deposits in areas with hard water. Evaporative media must be replaced on a regular basis to maintain cooling performance. Wood wool pads are inexpensive but require replacement every few ...
