Document Type and Number:
WIPO Patent Application WO/2024/124863
Kind Code:
A1
Abstract:
Disclosed in the present invention is a cascade parallel heat pump system, comprising a fresh air channel; a first heat exchange system, comprising a first heat exchanger, a second heat exchanger and a third heat exchanger which are arranged in parallel, the first heat exchanger being located in the fresh air channel; a second heat exchange system, comprising a fourth heat exchanger arranged in the fresh air channel, the second heat exchange system achieving heat exchange with the first heat exchange system by means of the second heat exchanger; and a third heat exchange system, comprising a fifth heat exchanger arranged in the fresh air channel, the third heat exchange system achieving heat exchange with the first heat exchange system by means of the third heat exchanger. The first heat exchanger, the fourth heat exchanger and the fifth heat exchanger are successively arranged in the fresh air channel. The cascade parallel heat pump system of the present invention can fulfill the purpose of heating fresh air from a low/medium temperature to a high temperature at a relatively low energy efficiency ratio, thus achieving energy saving, and timely regulation and control.
