Outdoor unit and air conditioning system provided with same

Abstract

The invention provides an outdoor unit and an air conditioning system provided with the outdoor unit. The outdoor unit comprises a shell, a fan, a first heat exchanger and a second heat exchanger, wherein a mounting cavity is formed by the shell in an enclosed mode; air inlets are formed in both the first side surface of the shell and the second side surface opposite to the first side surface; airoutlets are formed in the circumferential direction of the shell by taking the perpendicular bisector of the first side surface and the second side surface as the axis; the fan is installed inside the mounting cavity; the first heat exchanger is arranged at the air inlet in the first side surface; and the second heat exchanger is arranged at the air inlet in the second side surface. According tothe outdoor unit and the air conditioning system, hot air in the outdoor unit can be exhausted in time, components are prevented from being burnt out, and the service life of the outdoor unit and theair conditioning system can be prolonged.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an outdoor unit and an air conditioning system having the same. Background technique [0002] Axial flow fans have the characteristics of large flow and low static pressure. It is generally used in the outdoor fan system of split air conditioners, see figure 1 As shown, the existing outdoor unit is mainly composed of 1 to 2 sets of fans 2 and 1 set of "L" type heat exchanger 1 to realize the cooling / heating cycle. Its main feature is that the cooling / heating cycle system is simple , Easy system matching, stable performance. [0003] With people's increasing requirements for the diversification of building and air-conditioning functions and structural aesthetics, the outdoor unit is usually placed in a relatively small semi-enclosed space under the bay window platform, which greatly affects its air outlet and heat dissipation, especially when outdoor The air conditione...

Problems solved by technology

[0003] With people's increasing requirements for the diversification of building and air-conditioning functions and structural aesthetics, the outdoor unit is usually placed in a relatively small semi-enclosed space under the bay window platform, which greatly affects its air outlet and heat dissipation, especially when outdoor The air conditioners are evenly installed in the dense unit groups on each floor of the same building, resulting in the high temperature of the air intake of the outdoor unit on the upper floor, and the hot air cannot be discharged in time. In some cases, heat dissipation protection occurs, and in severe cases, components are burned, which greatly reduces the service life of the air conditioner.
