Project address: 12961.15 M2 heating project in Baoding, Hebei Province
The building is 1.9 meters above the ground floor
Customer requirements: meet the winter indoor design temperature: 20 ± 2 ℃
Unit selection: 12 Lipman a · c25-ac-s4 air source heat pump units are selected
Heating terminal: low temperature floor radiation heating is adopted at the end of winter heating
Highlights of the project:
It is 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.
Considering the 120 days of winter heating season in Baoding City, it starts on November 15 and ends on March 15 of the next year, which are November, December, January, February and March respectively. The load coefficient and energy efficiency ratio of units are also different according to the outdoor temperature.
Heating power consumption in November and March (energy efficiency ratio of the unit is 3.0): 648kw × 15h × 80% △ 3.0 × 30 days = 77760kw · H
Heating power consumption in December and February (energy efficiency ratio of the unit is 2.6): 648kw × 15h × 90% △ 2.6 × 60 days = 201877kw · H
Heating power consumption in January (unit energy efficiency ratio 2.4): 648kw × 15h × 100% △ 2.4 × 30d = 121500kw · H
The total heating power of the main engine is about 1137kw in winter
4315kw · 24kw · day
Winter: (374394kw · H + 43200kw · h) / 12961.15 m2 / 120 days = 0.29kw. H / m2 · day
Note: the above is estimated according to the heating load of the building combined with the energy efficiency ratio under the rated working conditions of the unit. The actual working time of the main engine will vary according to the user's terminal opening indoor temperature, weather changes and other factors. The above estimation is for reference only
