Heat storage components and air conditioners

Abstract

The invention provides a heat accumulation assembly and an air conditioner. The heat accumulation assembly comprises a heat accumulator, at least one heat exchange tube and at least one electric heating part, wherein the heat accumulator is provided with at least one fin and a cavity, and the cavity is used for containing heat accumulation materials; the heat exchange tubes are mounted on the heat accumulator and used for circulation of coolants; the electric heating parts are arranged on the heat accumulator; the fins are located on the peripheries of the electric heating parts and are parallel to the cross sectional surfaces of the electric heating parts. According to the heat accumulation assembly provided by the invention, the heat transfer area of the electric heating parts is effectively increased; by increasing the heat absorption area of the coolants circulating in the heat exchange tubes, the coolants can conduct heat exchange sufficiently and continuously so as to maintain a high temperature to facilitate fast, timely and complete defrosting of an outdoor heat exchanger, and then the good defrosting effect and the stable heating effect are guaranteed. The use comfortable degree of users is promoted. The electric heating parts can conduct heating uniformly, the requirements under different working conditions can be met, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a heat storage assembly and an air conditioner. Background technique [0002] The air conditioner in the related art usually uses the discharge temperature of the compressor to perform hot air defrosting. When defrosting starts, the four-way valve is reversed so that the outdoor heat exchanger releases heat, and the indoor heat exchanger absorbs heat, resulting in indoor ambient temperature. In this way, in a colder environment, the air conditioner runs the refrigeration cycle, which will cause the room temperature to be hot and cold, affecting the comfort of the user. In order to ensure the defrosting effect and the comfort of the user, an external heat storage component is usually added heat capacity and improve system stability, but the heat storage components in the related art have limited heat dissipation area and uneven heating, which makes the heat exchange of th...

[0002] The air conditioner in the related art usually utilizes the discharge temperature of the compressor to perform hot air defrosting. When defrosting starts, the four-way valve is reversed so that the outdoor heat exchanger releases heat and the indoor heat exchanger absorbs heat, causing the indoor ambient temperature to rise. In this way, in a colder environment, the air conditioner runs the refrigeration cycle, which will cause the room temperature to be hot and cold, which affects the comfort of the user. In order to ensure the defrosting effect and the comfort of the user, an external heat storage component is usually added thermal capacity and improve system stability, but the heat storage components in related technologies have limited heat dissipation area and uneven heating, which makes the heat exchange of refrigerant uneven, which leads to unstable defrosting and heating effects
