About ① heat exchanger freezing, 4 for some reason (in outdoor unit four operation) was frozen only two blocks of the block
Why do not the whole area if they happened to the setting of the expansion valve on the ② air conditioner design. Pressure and flow rate, etc. (RD350, RD400) for ③ compressor four, but the thermo of the indoor unit suction unit is one, or is happening driver settings as ④ frozen situation, primary distribution pipe and expansion valve 2 until the suction pipe after the heat exchanger and heat exchanger is frozen, with frost and has become. Possible causes included poppy from listed all (there is no answer only the status quo heat exchanger dirt) ⑤ heat exchanger freeze, but has become final of low pressure cut system lowers the gas pressure due to excessive cooling, and frozen If you want to water leakage in the case, it is necessary protection to stop before freezing. Do not have a strategy.
