[0006] The suction pipe 9 in the prior art is a circular elbow with a uniform diameter, and an oil return bend 10 is formed at the lowest end of the suction pipe bend. Since the gaseous refrigerant flowing through the oil return bend 10 contains liquid oil , when the air conditioner is running at low load, in order to ensure the oil return, the diameter of the suction pipe is generally selected to be small, but the small diameter will cause the pressure drop to be too large when it is running at full load

Embodiment Construction
[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0015] Such as figure 2 , 3 As shown, the split-type air conditioner outdoor unit with double ascending suction pipes of the present invention includes four sides of the outdoor unit, an exhaust grill is arranged on the front end surface, and a plurality of air inlets are arranged on the rear end surface. The casing; the chassis 2 arranged on the lower part of the casing and the components of the outdoor unit installed thereon; the compressor 3 arranged on the upper side of the chassis 2 and compressing the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant; arranged on the chassis 2 At the rear edge of the rear part, the condenser 4 that makes the refrigerant flowing in it exchange heat with the surrounding air; the fan motor 5 that is arranged above the center of the other side ...

The present invention discloses a split-type air conditioner outdoor unit with a double rising inhalation pipe, which comprises a housing, a chassis, a compressor, a condenser, a fan motor, an outdoor fan, a baffle plate, a liquid storage tank, and an inhalation pipe connected between an indoor set and the liquid storage tank and flowed the gaseous refrigerant and the liquid oil after heat exchange with the indoor set. Wherein the inhalation pipe is divided into a L-shaped first inhalation pipe and a L-shaped second inhalation pipe through a three-way oil gathering bend at one side of bending section of the bottom end of the inhalation pipe, the first inhalation pipe and the second inhalation pipe are merged through the three-way oil gathering bend at a vertical section of the inhalation pipe, and the caliber of the first inhalation pipe is less than that of the second inhalation pipe. The system of the invention operates with low pressure drop, and can ensure the oil return when the system operates at a low-load situation to solve the problem of the contradiction between the pressure drop control and the oil return. Particularly, the present invention has more obvious effect on frequency conversion air-conditioning whose change of the refrigerant flow velocity is large.
Description
technical field [0001] The invention relates to an air conditioner, in particular to a split type air conditioner outdoor unit with double ascending suction pipes. Background technique [0002] Generally speaking, an air conditioner is a cooling / heating household appliance installed on a wall of an indoor space such as an office or a home to cool or heat indoor air. An air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator to form a refrigeration / heating cycle. [0003] An air conditioner is composed of an outdoor unit installed outdoors and an indoor unit installed inside a building. The outdoor unit is provided with a condenser (outdoor heat exchanger) and a compressor, and the indoor unit is provided with an evaporator (indoor heat exchanger). [0004] The types of air conditioners are broadly classified into a split type air conditioner in which an outdoor unit and an indoor unit are separated from each other, and an integrated typ...
