It combines the advantages of both time-based and energy based billing systems in each deviceFan coil unitendinstallTime type billing device, used to detect the running time of valves and fan coil units in three levels: high, medium, and low. At the same time, a heat meter is installed on the main air conditioning water pipe of the floor (area) to measure the temperature of the floor (area)Air conditioning usageThe heat; Allocate the energy consumption of air conditioning in this floor based on the operating time of all fan coil units within the floor.

System features

Arrears cut-off function

When users do not pay the relevant fees, they can control to cut off the power or water valve (with an additional control module).

Cooling supply/Heating quality assurance

It is possible to set a starting temperature value for measurement when supplying cooling/Heating water temperature is higher than/When below this starting point, cold/The heat meter does not measure or accumulate energy.

Time segmented measurement function
Can be cold for an additional five time periods/Heat is measured and charged according to different time periods. For example: Monday to Friday working hours (every day)24Hours can be arbitrarily divided into3Closed period, Saturday, Sunday00:00～24:00Holidays, May Day, National Day, New Year's Day, Spring Festival, etc00:00～24:00During holiday periods.

Real time monitoring function

It can dynamically record the usage trend of users during a specific time period, providing a basis for users to raise objections to the measurement data.

Charging method

Total cost=Total electricity consumption of central air conditioning system x unit electricity price+System water consumption x unit water price+Management fee (optional)+Labor wages (optional)

Unit price of cold and heat (energy type)=Total cost/Total usage of central air conditioning cooling and heating meters (or total usage of central air conditioning cooling and heating building meters)

Floor cooling and heating meter (energy type) cost=Unit price of cooling and heating capacity multiplied by the usage of floor cooling and heating meters

Unit price of central air conditioning cooling capacity distribution meter (time type)=Cost of floor cooling and heating meters ÷ Total usage of central air conditioning cooling distribution meters on this floor

Cost of central air conditioning cooling capacity distribution meter (time type)=Unit price of central air conditioning cooling distribution meter x usage of central air conditioning cooling distribution meter
