Shell assembly of air conditioner outdoor unit, control method, air conditioner outdoor unit and air conditioner

Abstract

The invention discloses a shell assembly of an air conditioner outdoor unit, a control method, the air conditioner outdoor unit and an air conditioner. The shell assembly comprises a shell, a first air hood and a second air hood, wherein the shell is provided with a first air inlet and a first air outlet; the first air hood is provided with a second air inlet and a second air outlet, the opening degree of the second air inlet is adjustable, the second air inlet communicates with the outside, and the second air inlet further communicates with the first air inlet; and the second air hood is provided with a third air inlet and a third air outlet, the third air inlet communicates with the first air outlet, and the third air outlet communicates with at least one of the first air inlet and the outside. According to the shell assembly, the different load requirements are met by adjusting the air intake area and resistance of the first air inlet and changing the air intake volume, the air conditioner can perform refrigeration under low temperature, and influences on the refrigeration effect and the heating effect under normal temperature can be reduced to the greatest extent.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a housing assembly of an outdoor unit of an air conditioner, a control method, an outdoor unit of an air conditioner, and an air conditioner. Background technique [0002] Existing air-conditioning systems are sometimes installed in working conditions where there are a large number of heat sources indoors with high temperature and low outdoor temperatures. However, because the indoor has special requirements for air quality, low-temperature air from the outside cannot be directly introduced to cool the room, and the room needs to be cooled. The air-conditioning system will become unstable at low temperature below -5°C, and the system capacity will be greatly reduced. When the wind blows on the heat exchanger, the situation will be exacerbated. In order to directly blow cold air into the heat exchanger at low temperatures, a windproof panel is required. In the past,...

AI Technical Summary

Problems solved by technology

In the past, the design of the windproof panel was fixed, and at most it was only a simple snow cover. In this way, the cooling and heating of the unit will be affected by the same negative impact when the outdoor temperature rises.
