建筑空调系统节能技术措施探讨（Discussion on energy saving technical measures of building air conditioning system） In recent years, with the further development of economy, a large number of public buildings such as hotels, office buildings, shopping malls, hotel restaurants, sports venues and other public buildings have sprung up, the most with the central air conditioning system. The increase of building electricity consumption has brought great pressure to urban power grid, with the development of urban modernization. Building energy demand will further increase, power supply will be more tense, air-conditioning energy consumption is the main part of building energy consumption, accounting for about 50% of the total building energy consumption, so the energy saving of air-conditioning system is of great significance. At present, there are still a lot of waste in energy consumption of individual buildings: (a) individual architectural designers have one-sided pursuit of architectural facade effects, with little or no consideration for building energy efficiency design. The building shape coefficient (the ratio of building with outside air contact surface area and black volume) is too large, the window wall area ratio is too large, a lot of the glass curtain wall, building envelope insulation insulation performance is poor, resulting in enclosure heat loss is large, these factors greatly increase the cooling load of air conditioning. B) some construction units are only concerned with the one-time investment control, ignoring the cost of the air-conditioning system after the operation, and ignoring the energy saving requirements of the air-conditioning system. Most of this is caused by the disunity between investors and users, which makes it difficult to improve the energy saving design of air-conditioning systems. C) the operation and management level of some air conditioning systems is low. Although the air conditioning system design is reasonable, but the operation management le
