Low Ambient, Condenser Flooding, and Headmaster Valves

<p>In this podcast episode, Jeremy Smith comes on the podcast to talk about low-ambient controls, headmaster valves, charging, and condenser flooding.</p> <p>If our head pressure drops too much, we won't get enough of a pressure drop across the TXV. Pressures dictate the TXV function, so we need to make sure our systems give that valve what it needs to operate correctly. Three pressures operate a TXV: bulb pressure, spring pressure, and evaporator pressure. However, pressures throughout the system can also affect the pressures that act on a TXV.</p> <p>Condensers are sized for maximum heat rejection...
