Embodiment example 1

[0026] Such as figure 1 As shown, the present invention provides a low-noise, high-efficiency air-source heat pump outdoor unit, which includes a housing 1, an evaporator 2 disposed inside the housing, a mixed-flow fan system 3, and a heat pump module system 4. The mixed-flow fan system 3 The two air outlets are both arranged on the side of the casing 1 .

[0027] In the low-noise, high-efficiency air source heat pump outdoor unit provided by the present invention, the direction of the air outlet of the mixed flow fan and the direction of the length of the evaporator 2 form an included angle of 30°.

[0028] The evaporator 2 of the low-noise and high-efficiency air source heat pump outdoor unit provided by the present invention is L-shaped.

[0029] The low-noise, high-efficiency air source heat pump outdoor unit provided by the present invention includes one mixed flow fan system 3 described above.

Embodiment example 2

[0031] Such as figure 2 As shown, the difference from Embodiment 1 is that the evaporator 2 of the low-noise and high-efficiency air source heat pump outdoor unit provided by the present invention is I-shaped.

Embodiment 2

[0032] Other structures of Embodiment 2 are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention provides a low-noise high-efficiency air source heat pump outdoor unit which comprises an outdoor unit shell (1), and an evaporator (2), a mixed flow fan system (3) and a heat pump module system (4) arranged in the shell. Two air outlets of the mixed flow fan system (3) are formed in the front surface of the shell (1); or one air outlet is formed in the front surface of the shell (1), and the other air outlet is formed in the side surface of the shell (1); or the two air outlets are formed in the side surface of the shell (1). An airflow outlet direction of the mixed flow fan system (3) and a length direction of the evaporator (2) form a 1 to 90-degree included angle. The low-noise high-efficiency air source heat pump outdoor unit provided by the invention adopts the mixed flow fan system (3), so that the space of the outdoor unit can be fully utilized, the fan operation noise can be reduced and the heat exchange efficiency of the evaporator (2) can be improved on the basis of an existing outdoor unit, and the problem of 'air return short circuit' of the evaporator caused by air out of a centrifugal fan in the prior art can be effectively solved along an air out direction of the mixed flow fan.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular to an outdoor unit of an air source heat pump. Background technique [0002] Most of the air source heat pump outdoor units in the prior art adopt axial flow fan system and L-shaped evaporator, the noise is relatively high, and the heat transfer uniformity of the shorter section of the L-shaped evaporator is poor; the fan and evaporator occupy 2 / 2 of the shell. 3 space, the pipeline system layout space is small. [0003] A small part of the air source heat pump outdoor units in the prior art adopts a centrifugal fan system, which is the air intake from the rear side of the unit, and the air is discharged from the left or right side of the unit (or both sides at the same time). The cold air in the air is immediately sucked back by the evaporator, causing a "return air short circuit" and affecting the performance of the outdoor unit. [0004] A few air source heat pump...
