Mar 27, 2018 · The heat exchanger uses the combustion gases to warm the air, which is then distributed around the home. Exhaust gases from the combustion process are released through the flue to the outside of the home. [9] The heat exchanger in a gas furnace plays two roles: exchanging heat from the combustion process to the air blown over it and keeping ...
Jun 06, 2020 · The purpose of a pump down system is to prevent liquid refrigerant from “migrating” back into the compressor during an off-cycle. What are the main functions of a solenoid valve in liquid line? The primary purpose of a solenoid valve in a refrigerant liquid line is to prevent flow into the evaporator during the off cycle.
May 28, 2020 · The bypass valve – otherwise known as a pressure relief valve – is an integral part of the oil filter. The valve is designed to open when the oil filter becomes clogged or when the oil is too thick. This allows the oil to bypass the filter through a center tube. When this happens, the engine looses all oil pressure.
The evaporation process in rotary evaporator is influenced by the pressure and temperature employed. The lower the pressure and higher temperature will …
Nov 06, 2019 · For the water cycle to work, water has to get from the Earth's surface back up into the skies so it can rain back down and ruin your parade or water your crops or yard.
