Upper air supply type phase change and energy storage air conditioner utilizing natural cold source

Abstract

The invention discloses an upper air supply type phase change and energy storage air conditioner utilizing a natural cold source. The air conditioner is characterized by comprising a case, an evaporator, a centrifugal fan and a phase change heat exchange module; the evaporator, the centrifugal fan and the phase change heat exchange module are sequentially installed in the case from top to bottom, or the evaporator, the phase change heat exchange module and the centrifugal fan are sequentially installed in the case from top to bottom; and the evaporator is connected to a condenser, a throttling part and a compressor of a refrigerating unit through a pipeline. According to the air conditioner, the external free natural cold source is fully utilized according to the natural environment conditions of different climate zones, and the energy utilization efficiency is high; and cold storage is carried out by utilizing the cold accumulation capacity of the phase change heat exchange module and by fully utilizing external low-temperature air at night, the cold energy is released in the high-temperature time period in the daytime, and therefore the starting time of the refrigeration compressor in the daytime is greatly shortened, and the electric energy consumption is reduced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of phase change material energy storage air conditioners, in particular to an upward air supply type phase change energy storage air conditioner utilizing a natural cooling source.
