why rotary compressor on the heat pump and air conditioning, and compressor piston on the refrigerator and freezer?
the strong point of the piston is the good performance at high pressure so large temperature difference between hot and cold, this gift is needed for a refrigerator and even more a freezer
the strong point of the rotary is the large flow in a small footprint ... the weak point is the pressure: it corresponds well to the heat pump or we want a great power at low temperature range. a large temperature difference the heat pump is no longer useful and resistance is sufficient
