Cellar cooling system . Evaporator iced up, landlord tried to break off the ice with a screwdriver and wham, pierced a nice hole in a tube.
Fitted new drier and started up the unit. System low pressure went into a deep vacuum. I thought , well there must be moisture , ice water ingress and expansion valve is frozen up, but after delivering some warmth to the valve system remained in deep vacuum. Then I noticed ice, frost on the liquid exit from the heat exchanger. I remember reading somewhere that these components are prone to damage. I bypassed the heat exchanger.
How common is this problem and whats the cause?
