Hello for all,
We have CLIMAVENETA AWR-HT/CA-E 0302 and problem with defrost.
In cold days, when temperature is approx. or below 0, the coils become icy and units stops by Low Pressure alarm. I noticed that defrost starts and ends in approx. 10 - 15 s. I looked at the process and found that then coils is very icy, defrost starting (compressor not restarting) and pressure on LP side very quickly falls below 1 bar and defrost is terminating due to low pressure I suppose and some ice remains on coils.
Units are with standards parameters and factory refrigerant charge.
Maybe somebody had similar unit and solved this problem. Also maybe somebody know right refrigerant charge? We got unit with 19,5 kg charge. In this document - http://www.climacon.com/storage/_fil...2_EN_(389).pdf I found that refrigerant charge is 40 kg.
Thanks all for support.
