What is the principle of billing for central air conditioning flow? The core principle of central air conditioning flow billing is to convert the actual consumption of cold and heat by users into fees, similar to water and electricity meters at home. 1. Equipment operation foundation: Flow meters and temperature sensors will be installed in the pipelines of the central air conditioning system. The Hongchang flow meter is responsible for measuring the circulating water flow rate, while the temperature sensor records the temperature difference between the inlet and outlet water. Through these two pieces of data, the system can calculate the actual consumption of cold/heat by the user (in kilowatt hours). 2. In the household metering mode, billing controllers are installed near the air outlets of each independent space (such as offices and shops). When users use air conditioning, the controller collects real-time data on usage duration, temperature settings, air volume levels, etc., combined with the flow and temperature parameters masked by the main system, and finally generates personalized energy consumption bills. 3. Cost conversion characteristics: In most cases, the cooling capacity pricing+basic fee model is used. For example, office buildings usually charge a basic maintenance fee of 20-50 yuan/m ² per month, and then charge an additional 0.2-0.8 yuan per kilowatt hour based on actual usage. This design not only covers equipment maintenance costs, but also promotes energy conservation for users - raising the temperature by 1 ℃ or reducing usage time can significantly reduce bills. In recent years, some intelligent systems have added time-sharing pricing functions, such as the cooling unit price during the peak electricity consumption period at noon being 30% higher than at night. Some high-end shopping malls also combine indoor crowd monitoring to automatically raise the temperature in areas with low foot traffic. This dynamic energy-saving technology can reduce overall energy consumption by 15% -20%.

2. What is the specific mode of billing for central air conditioning flow?

The billing mode for central air conditioning flow can be summarized as: calculating energy consumption costs based on the amount of chilled water circulation multiplied by the duration of use multiplied by the unit price, which is commonly used in commercial offices or residential areas with separate charges.

2. Equivalent time measurement: Combined with the comprehensive calculation of water temperature difference and flow rate, it is often used in mixed billing scenarios. The calculation formula is: energy consumption=flow rate x (inlet temperature - outlet temperature) x usage time. This method will more accurately reflect the actual efficiency of cold and heat exchange, and is often found in places such as hotels and hospitals that require high temperature control accuracy.
