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 ...
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
A simple stylized diagram of the refrigeration cycle: 1) condensing coil, 2) expansion valve, 3) evaporator coil, 4) compressor. Cooling in traditional air conditioner systems is accomplished using the vapor-compression cycle, which uses a refrigerant's forced circulation and phase change between gas and liquid to transfer heat.
Domestic absorption refrigerator. 1. Hydrogen enters the pipe with liquid ammonia 2. Ammonia and hydrogen enter the inner compartment. Volume increase causes a decrease in the partial pressure of the liquid ammonia. The ammonia evaporates, taking heat from the liquid ammonia (ΔH Vap) lowering its temperature. Heat flows from the hotter ...
In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers. Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The ...
In the evaporator and condenser, the phase change of pure ammonia is used to complete the external absorption or heat release. [4] Like a traditional heat pump, the refrigerant (ammonia) is condensed in the condenser, and heat is then released; the pressure is dropped after the expansion unit and the refrigerant is evaporated to absorb heat.
Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
Between points 4 and 5, the liquid refrigerant goes through the expansion valve (also called a throttle valve) where its pressure abruptly decreases, causing flash evaporation and auto-refrigeration of, typically, less than half of the liquid. That results in a mixture of liquid and vapour at a lower temperature and pressure as shown at point 5.
