1. Project address: Jingyuan County, Baiyin City, Gansu Province;
2. Building structure: the building is a three-layer Street gate, the design area is the first floor of the building, the floor height is 4.5m, the design area is about 107 m2, the building envelope is 300 mm thick aerated block, no thermal insulation, aluminum alloy double-layer window.
3. Customer requirements: meet the user's indoor temperature in summer: 26 ± 2 ℃, winter indoor temperature: 20 ± 2 ℃
4: Unit selection: two a.c3-ac / JY (220 V) Lipman air source heat pump ultra-low temperature air conditioning units are adopted
5. Indoor end: horizontal concealed fan coil unit is adopted in summer, and original floor radiant heating is used in winter.
In winter, the operating power of air source heat pump is about 7268kw. H, with an average of 0.45KW. H per square meter per day
(the heating time in winter is from November 15 to March 15 of the next year. It is estimated according to the heating heat load of the building and the energy efficiency ratio under the rated working condition of the unit. The actual operating power of the main engine will be changed according to the indoor temperature of the user's terminal, weather changes and other factors.)
