Wall piercer

Abstract

The invention discloses a wall penetrating machine. The wall penetrating machine comprises an air duct component (1) arranged at the outdoor side, and a blade (2) arranged in the air duct component, wherein the blade (2) is a cross-flow blade; the air duct component (1) comprises an air outlet arranged corresponding to an outdoor air outlet surface of the wall penetrating machine, and two end plates respectively arranged at the two sides of the air outlet; and the two ends of the blade (2) are respectively arranged on the two end plates. The wall penetrating machine, provided by the invention, sets the blade as the cross-flow blade to fit the air duct component with adaptive structure, so that the air volume is increased, the air volume of an outdoor heat exchanger penetrating through the wall penetrating machine is increased, and the heat exchange efficiency is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a wall-piercing machine. Background technique [0002] The wall-through unit is the general term for PTAC (window air conditioner) and PTHP (air-to-air heat pump), and its outdoor side is provided with axial flow blades to ventilate the outdoor side heat exchanger. [0003] Please refer to figure 1 , figure 1 It is a wall-piercing machine in the prior art. [0004] The axial flow fan 03 is fixed on the axial flow duct assembly 01 by a motor 02, and the outdoor heat exchanger 04 is located on the side of the axial flow fan 03 away from the axial flow duct assembly 01. Because the wall piercing machine is affected by the air inlet and outlet methods, the air volume cannot be compared with the air volume of the separate external unit (taking the 12K model as an example, the air volume of the separate external unit is 2000m 3 / h, while the wall-piercing machine is only 1000m ...

AI Technical Summary

Problems solved by technology

Because the wall-penetrating machine is affected by the air inlet and outlet methods, the air volume cannot be compared with the air volume of the split external unit (taking the 12K model as an example, the air volume of the split external machine is 2000m 3 / h, while the wall penetration machine is only 1000m 3 / h), and the size of the heat exchanger 04 of the outdoor unit of the through-wall unit is also much smaller than that of the split unit (about 3 / 5 of the size of the split outdoor heat exchanger), which affects the heating ( PTHP) or refrigeration (PTAC) heat transfer efficiency

The casing of the wall penetration machine is a standard size (limited by American building standards), and the casing cannot be enlarged, which limits the way to increase the area of ​​the outdoor heat exchanger 04 and the size of the axial flow fan 03

Therefore, even by expanding the area of ​​the outdoor heat exchanger 04 and the axial flow fan 03 feet, the heat exchange efficiency cannot be effectively improved.
