Introduction

The unit works with gas-burning combined cooling, heating and power cogeneration system (CCHP). Without extra energy consumption, it uses high-temperature flue gas as driving force to extract low-quality heat and reduce the temperature to lower than 30℃. In winter, the heating ability of the system is increased by 50% compared with the traditional absorption unit with low-temperature water. In summer, the system acts as the cool sink of central air-conditioner to accommodate the waste heat which should have been discharged to the environment through cooling tower. Thus, there will be a balance of heat among seasons and the system could work efficiently for long time.

Driving source: high temperature flue gas

Remaining heat that can be utilized: soil, underground water, urban sewage

Heat gained: used for regional heating and cooling
