Hi all
i am making a system to de-humidify air.
The system consists of cond unit, evap, internal equalized tev, drier, sight glass, hot gas bypass valve to maintain close control on suction temperature.
The system has a duty of around 900watts running on R404a maintain a evap temperature of 0deg C.
Pipe runs are very short (only about 1mtr)
Do i need to fit a llsv for pump down when the humidity has reached it's set point??? and the comp cycle's off??
If i don't use pump down will the evap fill with liquid emptying the condenser/reciever, threatening the comp on re start.
