Abstract
The utility model discloses an electronic expansion valve throttled high temperature environment special air-conditioning set, belonging to the refrigeration technology. A thermal expansion valve of a high temperature environment special air-conditioning set in the prior art cannot completely response the actual opening degree needs for the running of the set, as a result, the set cannot fully perform the maximum performance most of the time. An evaporating pressure sensor and a suction temperature sensor are arranged between the outlet of an evaporator and the inlet of a compressor; the evaporating pressure signals of the evaporating pressure sensor and the suction temperature signals of the suction temperature sensor are acquired by an electronic expansion valve controller to figure out the actual suction super-heated degree of the set; and the opening degree of the electronic expansion valve is controlled by comparing the actual suction super-heated degree with a target super-heated degree, thus, the opening degree of the electronic expansion valve can be quickly adjusted to the optimum value, thereby ensuring the efficient and reliable running of the set.
