Abstract

The invention relates to the technical field of heat pumps, in particular to an air source heat pump. The air source heat pump comprises a compressor, a first heat exchanger, a first throttling structure, a second throttling structure, a second heat exchanger and a gas-liquid separator. The compressor, the first heat exchanger, the first throttling structure, the second throttling structure and the second heat exchanger are sequentially and cyclically connected. The gas-liquid separator is arranged between the first throttling structure and the second throttling structure and is provided witha first opening, a second opening and a third opening, wherein the first opening and the second opening are connected with the first throttling structure and the second throttling structure correspondingly, and the third opening is connected with the compressor. The air source heat pump has the high heat exchange amount and heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to an air source heat pump. Background technique [0002] A heat pump is a device that can obtain low-level heat energy from air, water or soil in nature, and perform work through electric energy to provide a high-level heat pump that can be used by people. The ideal thermodynamic cycle system of a heat pump consists of isobaric evaporation, isentropic compression, isobaric condensation, and isenthalpy throttling. gaseous state for efficient heat transfer. However, the heat pump cycle is a non-ideal thermodynamic cycle system, and the Freon at the outlet of the throttling element is generally in a gas-liquid two-phase mixed state. The wall forms an air film, which increases the heat transfer resistance of Freon and reduces the evaporation efficiency of liquid Freon. Therefore, the overall heat transfer capacity and heat transfer efficiency of the heat pump are greatly affected....
