Description

technical field

[0001] The invention relates to a high-efficiency energy-saving technology of a building air-conditioning system, in particular to a high-efficiency energy-saving air-conditioning system suitable for the step-by-step utilization of cooling capacity for district cooling and its realization method. Background technique

[0002] At present, with the rapid development of my country's economy, the demand for energy has increased rapidly, and the contradiction between supply and demand of energy has become increasingly acute. On the other hand, the reality is that my country's energy utilization efficiency is far lower than that of developed countries. Therefore, an effective way to solve the current energy dilemma in our country is to improve energy utilization efficiency. my country's building energy consumption accounts for about 30% of the country's total energy consumption, and the unit energy consumption is much higher than that of developed countries; the e...
