Abstract

The invention provides a heat pump system and an air conditioner, wherein the heat pump system comprises a compressor component, a heat exchanger and an air supplementing device which are connected inproper sequence, the compressor component comprises a first compression cylinder set and a second compression cylinder set which are arranged in parallel, the first compression cylinder set comprisesa first compression cylinder and a second compression cylinder which are arranged in series, the second compression cylinder set comprises a third compression cylinder and a fourth compression cylinder which are arranged in series, the air supplementing device comprises a first air supplementing device and a second air supplementing device, the first air supplementing device is used for supplementing air for the first compression cylinder set, and the second air supplementing device is used for supplementing air for the second compression cylinder set. The technical scheme of the invention solves the problems that the throttling loss in the prior art is high and the heat pump efficiency is low.

Description

technical field [0001] The invention relates to a heat pump device, in particular to a heat pump system and an air conditioner. Background technique [0002] In the prior art, the heat pump device using two-stage compression and intermediate air supply can effectively improve the problem of poor heating performance of the traditional single-stage compression heat pump device under low temperature and ultra-low temperature conditions, and has been widely used at present. However, in the traditional two-stage compression heat pump device, no matter it is a single two-stage compressor or multiple two-stage parallel compression groups, there is only one air inlet with the same pressure. When the indoor and outdoor temperature difference is large (such as indoor 20 ℃, outdoor -25 ℃), due to the large compression ratio, there will still be a large throttling loss, resulting in low energy efficiency. [0003] Further, in order to reduce the throttling loss, the commonly used metho...
