V 9 urah delovanja danes že 10 defrostov.
Sem zdaj pogleda navodila, ki jih je za svojo Kitajko prilepil stromar-elektronik, pa kot zanimivost čisto na koncu piše, kako preprečit ozebline toplotne črpalke (mišljen pa je protokol preventivnega zagona obtočne črpalke, če TČ ne deluje in temperature padejo pod 0). Kitajci pa njihova angleščina...
Torej, osnovni protokol na Kitajki je sledeč...
11.1 Defrosting
The defrosting is necessary only in heating mode. Sequences of the defrosting:
1- Start
The defrosting is engaged if the following conditions are at the same time fulfilled:
- The defrosting sensor temperature goes down to h2 (-1°C).
- The compressor runs without stopping for 6 minutes.
- The compressor had run totally h1 (35 minutes).
2- The compressor and the fan stop.
3- After 60 seconds, the 4 way valve shifts.
4- Two minutes after its stop, the compressor starts alone and the accumulated freeze on the gills becomes melting, what is generally with steam cloud.
5- Stop:
The defrosting stops if one of the following conditions is fulfilled:
- The detected temperature by the copper coil temperature goes up to h4 (20°C).
- The compressor had run totally h3 (10 minutes).
6- The compressor stops and the fan starts.
7- After 2 minutes the 4 way valve shifts.
8- Three minutes after its stop the compressor starts for restarting in heating mode.
Mašino pa lahko preko upravljalnika tudi "prisiliš" v protokol defrosta.
Glede nastavitev pa je v navodilih sledeče...
Defrosting Cycle 20─99 minutes (default 35 minut)
Defrosting temp. setting -15℃─1℃ (default -1℃)
Defrosting time setting 5-20 minutes (default 10 minut)
Exit defrosting temp. setting 1℃─40℃ (default 20℃)
Če jaz to zdaj prav razumem, je najpomembnejši "signal" TČ, da začne z defrostom, zunanja temperatura. Kar je po mojem hudo sporno.
