Hello, i have a few questions about a walking freezer.
i have a 6ft by 8ft walkin freezer with 404a in it (factory sized and Installed)
it had a small leak in the receiver and had to have it replaced.
cost me over 800$ to replace the receiver evacuate and recharge system with 404a.
the unit will not get below 14f degrees at night and below 19 during the day time.
i put some gauges on it and the low side is 24# and the high side is 275# in the mid afternoon with ambient air temperature of 92f.
The unit runs 24 hours a day until it goes into defrost twice daily.
The evaporator coil is not iced over and air flow is very good.
The condensor also has good airflow and is in the shade inside its covered housing.
there are no bubbles in the sight glass and it is full of liquid.
what can be done to see if the unit if working properly, the technician that did the repair is reputable but he charges $ just to come look at a unit.
i have gauges and i am 608 certified to purchase refrigerant and repair small refrigeration units that i currently own. i just dont know about bigger units like walkin freezers and such.
i appreciate any help you can offer.
