Intercontinental Hotel Shanghai Pudong replaced its original steam heating system with 4 CO2 heat pump units to supply the hotel's 100 tons per day hot water demand. This reduced annual operating costs from 30.66 million yuan to 3.45 million yuan, saving 27.21 million yuan. The CO2 heat pump units provide reliable and safe operation while meeting hot water needs. They also effectively lower energy costs and achieve goals of energy savings, emissions reductions, and cost reductions.

4. Project Overview
项目概况
Intercontinental Hotel Shanghai Pudong has 398 elegant rooms, 6 floors of clubs, 8
floors of non-smoking floors and 78 business suites and InterContinental club suites.
The hot water demand for the hotel is 100 tons per day. The original hot water heating
system used commercial (outsourced) steam to supply each user after heat exchange.
This system has a higher operating cost.
上海锦江汤臣洲际大酒店，酒店共设398间高雅客房，6层俱乐部楼层，8层无烟
楼层以及78间商务套房及洲际俱乐部套房。酒店生活热水需求量100吨/天，酒店原
热水热系统采用商用（外购）蒸汽经热交换后供应各用户，热水系统的运行成本较
高。

5. Transformation Plan
改造方案
Through investigation and research, the hotel adopted 4 sets of one-time heating CO2
heat pump units to replace the original steam heat exchange to meet the hotel hot water
supply. Those CO2 heat pump unites are developed and produced by “Dongqi Technology”.
酒店通过调研，采用了“东启科技”研制、生产的一次式加热的CO2热泵机组4台替
代原蒸汽换热方式以满足酒店热水供水。
At the same time, the CO2 heat pump absorbs the heat in the air while preparing the hot
water and the cold air emitted by the CO2 heat pump is introduced into the laundry room
through the air dust. By doing this, the air conditioner of the laundry room can be replaced.
同时，CO2热泵制备热水时吸收空气中的热量后散发的冷风通过导风管引入洗衣房，
替代了洗衣房的冷空调。

7. Application Evaluation
应用评价
Since the hotel selected CO2 heat pump hot water
unit produced by “Dongqi Technology”, the
operation is safe and reliable. Meanwhile, the hot
water demand for hotel is satisfied. The energy costs
are reducing effectively and achieve the goal of
energy saving, emission reduction and cost reduction.
酒店选用“东启科技”生产制造的CO2热泵热水
机组至今，设备运行安全可靠，也充分满足了酒
店的热水用水需求，有效降低了能源成本，达到
节能减排、降低成本的目的。
