Outdoor unit of split wall-hanging type air-conditioner

Abstract

The invention discloses an outdoor unit of a split wall-hanging type air-conditioner. A throttling device is an electronic expansion valve and one-way valve combination device, the lengths and the specifications of an auxiliary refrigeration capillary tube and an auxiliary heating capillary tube can be adjusted according to requirements, and the best throttling effect is accordingly achieved; a chassis of the air-conditioner is of a novel structure, a groove position is additionally arranged on the basis of a chassis of an existing air-conditioner through optimization design, and the chassis can be fixed for electric heating. Compared with the prior art, the outdoor unit of the split wall-hanging type air-conditioner has the advantages that the heating amount can be improved, the low-temperature defrosting problem can be solved, and the outdoor unit can be suitable for common climate and ultra-low-temperature areas.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a split wall-mounted outdoor air conditioner. Background technique [0002] Air conditioners are also called air conditioners. Air conditioners are devices that process the temperature, humidity, purity, and airflow speed of the air to meet people's production and living needs. They are referred to as "air conditioners" for short. [0003] The climate in the Nordic region is characterized by low temperature and high humidity all year round, which imposes strict requirements on air conditioners. At present, because the conventional air conditioner outdoor unit cannot meet the use requirements of this area, it is mainly due to the following two defects: [0004] 1. The throttling effect cannot reach the best state, especially in ultra-low temperature conditions (-20°C or lower), the cooling / heating tends to be two extremes, which cannot meet the throttling requirements of the air c...

AI Technical Summary

Problems solved by technology

At present, because the conventional air conditioner outdoor unit cannot meet the use requirements of this area, it is mainly due to the following two defects:

[0004] 1. The throttling effect cannot reach the best state, especially in ultra-low temperature conditions (-20°C or lower), the cooling / heating tends to be two extremes, which cannot meet the throttling requirements of the air conditioner;

[0005] 2. In low-temperature and high-humidity areas, the defrosting of the chassis and condenser is not clean, which affects the overall heat exchange effect of the air conditioner;
