Problems solved by technology

The billing method apportioned by area, regardless of whether the user uses more or less or even does not need to pay the central air-conditioning fee is the same, which is obviously unreasonable
The method of statistical billing is relatively fair, but this billing method cannot fully reflect the heat exchange amount actually c...

Embodiment

[0048] Such as figure 1 As shown, this figure is an example of a two-pipeline quantitative water system in the same way as the closed loop pipeline layout. The present invention is composed of a data transmission network 2, a water temperature sensor module 4, a first water pressure sensor module 5, a temperature controller 8, an air temperature sensor module 9, a WIFI router 11, a management server 12, a second water pressure sensor module 13, and the like.

[0049] The water temperature sensor module 4 is connected to the management server 12 through the data transmission network 2 .

[0050] The first water pressure sensor module 5 is connected to the management server 12 through the data transmission network 2 .

[0051] The second water pressure sensor module 13 is connected to the management server 12 through the data transmission network 2 .

[0052] The temperature controller 8 communicates with the management server 12 through the WIFI router 11 .

[0053] The temper...

Abstract

Disclosed is an indirect measurement type central air conditioner measurement billing and charging system. According to the system, the water temperature of a refrigerant of a central air conditioner is collected in a centralized mode, the indoor temperature of each room and the real-time working condition of each fan coil are collected separately, the data are combined with heat exchange parameters of the fan coils, and therefore the heat exchange amounts of the fan coils are obtained through calculation and serve as the measurement billing basis. Compared with a direct refrigerant measurement system, the indirect measurement type central air conditioner measurement billing and charging system has the advantage that the investment of measuring devices can be saved. Compared with the mode of billing according to the area and the time, the mode of the indirect measurement type central air conditioner measurement billing and charging system has the advantage that a more reasonable charging rule is provided. The indirect measurement type central air conditioner measurement billing and charging system can be combined with a temperature controller to form an integrated product, and no additional investment is basically required when the system is applied to buildings. The indirect measurement type central air conditioner measurement billing and charging system can be independently applied to practical billing, and can also be combined with the modes of billing according to the time and billing according to the time and levels to be used, and therefore billing choices are various, and diversified demands of various users can be conveniently met.

Description

technical field [0001] The invention is a central air-conditioning metering and billing system, which is a management system for calculating the charging amount according to the heat exchange amount. Background technique [0002] The current central air-conditioning charging methods mainly include: charging by area, billing based on the start-up time or the opening time of the refrigerant valve combined with the statistical billing of the wind speed of the fan of the coil fan, billing according to the power consumption of the coil fan, direct charging Measuring the refrigerant flow rate and the temperature difference between the refrigerant entering and leaving the coil fan, measuring the actual heat exchange amount, metering and billing, etc. The billing method apportioned by area, regardless of whether the user uses more or less or even does not need to pay the same central air-conditioning fee, is obviously unreasonable. The method of statistical billing is relatively fa...
