スヒータを取イマ１け、常時通電加熱を行なっていた。Conventional configuration and its problems Conventionally, in solar water heaters that circulate refrigerant, when the system is restarted after being stopped for a long time, a large amount of the refrigerant dissolved in the refrigerating machine oil becomes steam. However, at this time, the so-called oil foaming phenomenon occurs, causing the refrigerating machine oil to bubble violently.
There is a risk of destroying the compressor cylinder. For this reason, in the past, a crankcase heater was used to heat the refrigerating machine oil in the crank chamber to raise its temperature and expel the refrigerant from the refrigerating machine oil, and to perform constant energization heating.
