Mar 02, 2016 Unlike distillation, the reflux process is used in chemistry to accelerate a specific reaction thermally. This is done by conducting it in a controlled high temperature. The role of a condenser here is to cool down the generated vapours and convert them back into the liquid form. The liquid component is then sent back to the boiler.

Mar 19, 2020 What is the purpose of a Txv valve? A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant released into the evaporator thereby keeping superheat, that is, the difference between the current ...

May 15, 2018 Thermoelectric Refrigeration. Thermoelectric refrigeration systems are unique from the three other types of refrigeration in that no refrigerant or water is used.
