What is purge mode HVAC?
Regarding this, what does purge mean on AC unit?
"Purging" is the process of clearing an air conditioner's (AC's) unit's internal lines and hoses. This is frequently done before recharging freon but. many newer model AC units, such as Honeywell units, purge the system on startup.
Beside above, how do you purge air from a refrigeration system? Air in the system can be removed by collecting the system gas in the condenser, leaving the condenser cooling water on and venting out the air from the top of the condenser because air will not be condensed in the condenser but remains on top of the condenser above the liquid refrigerant.
Also question is, what does purge light mean on Honeywell?
PURGE Solid when in purge (lasts 2 minutes at power-up and after a call for heat or cool). Blinking when the DATS sensor has failed, or the wires are shorted or open. Will blink for 3 minutes at power-up if DATS is not present.
What happens if air gets in AC system?
When air enters a refrigeration system, it collects in the top of the condenser and is trapped. Air will cause a reduction in condenser surface area, which will cause a high condensing pressure. Air can enter the refrigeration system through a leak in the low side of the refrigeration system.
