——
  • Case overview
The project is located in three middle schools in Weiyuan County, Dingxi City, Gansu Province. The construction area of Shangwan middle school is 4700 square meters, qijiamiao middle school is 5500 square meters, and wuzhu middle school is 6200 square meters, with a total of 16400 square meters. In order to meet the needs of school heating in winter, 24 Lipman air source heat pump units are selected for heating.

Project Overview:

Project address: three middle schools in Weiyuan County, Dingxi City, Gansu Province (Shangwan middle school: 4700 square meters, qijiamiao middle school: 5500 square meters, wuzhu middle school: 6200 square meters)

Project demand: heating in winter

Building type: energy saving building

Indoor terminal: air conditioning terminal

System design: 380V power distribution system, using Lipman commercial air source heat pump water cycle unit

Unit selection:

1: Shangwan middle school, 4700 m2, with 7 Lipman a.c25-ac-s4 air source heat pump units;

2. Qijiamiao middle school, 5500 m2, with 8 Lipman a.c25-ac-s4 air source heat pump units;

3: wuzhu middle school, 6200 square meters, with 9 Lipman a.c25-ac-s4 air source heat pump units;

A total of 16400 m2, 24 units

Highlights of the project:

Intelligent control: easy to operate. The unit is controlled by microcomputer. It can be operated by wire or panel. It can set time and temperature, add cold water and warm hot water automatically, and display the fault of the unit. It can also realize equipment management automation and energy management automation through centralized monitoring of central computer.

Operation cost:

The electricity charge is calculated according to the information provided by customers in winter of 0.5 yuan / kW · h. The winter heating season in Weiyuan, Dingxi, is 150 days. It starts from November 1 to March 31 of the next year, which is November, December, January, February and March. The load coefficient and energy efficiency ratio of the unit are also different according to the outdoor temperature Annual weather conditions, winter 150 days full load heating cost estimation comparison:

Serial number Heating mode Monthly average heating cost (yuan / m2)
one Air source heat pump five point four nine
two Electric heating thirteen point eight
