Constant speed air conditioning compressor speed constant, below 0 ° C compressor power is ac electric motor low, in fact there is no heating effect; With high frequency, frequency conversion air conditioning low temperature so as to meet the needs of users. There is only one constant speed air conditioning compressor speed, not possible when full of strong; Frequency conversion air conditioning in just 220v electric motor boot or on a long, large temperature difference between indoor and outdoor, and can realize high frequency strong operation. Each such as current protection of constant speed air conditioning needs to stop the compressor; Frequency conversion air conditioning when Single phase motor happen to protect both with appropriate frequency reduction of running buffer, which can realize non-stop protection, does not affect the use of the user.
