Abstract

The invention provides an air conditioner unit which can achieve the refrigeration and heating at the same time. The air conditioner unit comprises an outdoor unit, a refrigerant distributor and an indoor unit. The outdoor unit, the refrigerant distributor and the indoor unit form a complete circulation system by a connecting pipeline; wherein, the refrigerant distributor comprises a high pressure gas / liquid separator, an electronic expansion valve A, an electronic expansion valve B, and a four-way valve which is corresponding to the indoor unit, and the aims of the refrigeration and the heating of the air conditioner unit are achieved at the same time by controlling the flowing direction of each four-way valve. Furthermore, the refrigeration and the heating can be achieved at the same time by precisely controlling the flux distribution when the outdoor temperature ranges from minus 5 DEG C to 30 DEG C; the maximum energy-saving effect can be achieved under the situation of providing refrigeration and heating at the same time.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning unit capable of cooling and heating at the same time. Background technique [0002] The air conditioner unit capable of cooling and heating at the same time in the present invention means that in a refrigerant circulation system, the indoor unit can choose the cooling and heating modes arbitrarily, and realize the cooling and heating functions at the same time. The basic principle is to effectively transfer the heat exchanged energy from the outdoor side to the indoor side and utilize it to achieve the purpose of energy recovery. For the above-mentioned simultaneous cooling and heating air-conditioning unit, when the indoor cooling and heating loads are equal, the outdoor side stops heat exchange, the energy is fully recovered, and the compressor only needs to output the cooling or heating capacity. It can not only output cooling capacity, but also p...
