Problems solved by technology

At present, many central air-conditioning metering methods still have a certain degree of limitation. They have not fully realized on-demand billing and rigorous and scientifically calculated billing according to volume, which is not conducive to central air-conditioning users to actively reduce energy consumption in line with the principle of saving. Consume clearly

Embodiment 1

[0056] Example one: see figure 1 , figure 2 , The charging method of the fixed air volume temperature difference type central air conditioner of the present invention, for each billing unit of the same central air-conditioning system, install temperature sensors at the air conditioning inlet and outlet of the user of the billing unit to collect the temperature of the inlet and outlet at the same time. The fan status recognition device detects the different gear status of the air conditioner fan, and the charging method realizes the on-demand charging of the central air conditioner through the following steps:

[0057] (1) First, set the wind speed of a certain gear state of the user's air-conditioning fan to a corresponding predetermined value ki,

[0058] (2) In the case of detecting the operation of the fan, judge whether the temperature difference between the inlet and outlet of the air conditioner reaches a preset initial value,

[0059] (3) When the temperature difference b...

Embodiment 2

[0066] Embodiment 2: This embodiment is a specific implementation of the charging device of the present invention. For the configuration of the charging device unit module, see figure 1 , The charging device contains a core computing unit, as well as a peripheral temperature acquisition unit and a fan operating state identification unit. image 3 Schematic diagram of the functional modules of the core computing unit. In the figure, U1 is the CPU, U2 is the time monitoring memory, and U3 is the uplink communication RS485 bus communication chip.

[0067] See Figure 4 , Figure 6 , The central processor in the core CPU module uses 89S52, or any one of AT89C52, P89C54BP, P89C58A, MC68HC11A8, MC68HC11E9, MC68HC16, PIC16C877A, EM78P447, MSP430F147, MSP430F435, E78C52D, E78E58B and subsequent compatible chips. The four I / O ports of the CPU are respectively connected to the corresponding interfaces WDOG, W_SO, W_CLK, W_DATA of the time monitoring storage module. These interfaces can be ...

Embodiment 3

[0071] Embodiment 3: Refer to the specific circuit Figure 4 ~ Figure 11 , Figure 17 . The device has an on-site display module. The difference from the second embodiment is that the user does not install a door-in valve, and the valve control / detection module controls the power circuit of the fan to realize the prohibition of arrears.

Abstract

The invention relates to a central air conditioning charging method and charging device. The constant air volume temperature difference type central air conditioning charging method and charging device comprise the following steps: installing temperature sensors on the air inlet and the air outlet separately of every charging unit in the same central air conditioning system, at the same time testing gear state of every user's air conditioning fan by the fan state recognizing device, setting up different gear wind speeds of users' air conditioning fans to different corresponding predetermined values in advance, when the air conditioning fan is operated under a certain gear and the temperature difference of the air inlet and the air outlet reaches the initial value, fetching the predetermined value corresponding to the current gear speed of the air conditioning of user, calculating the computational energy which is consumed by the users' air conditioning fan of the charging unit according to the heat calculation formula under the constant air volume constant state, and sharing the air conditioning fees according to the proportion of the sum of computational energy of every gear of the air conditioning to the total computational energy of central air conditioning system. The measure temperatures are collected on the inlet and the outlet of air conditioning directly, which reflects the using effect better.

Description

(1) Technical field: [0001] The invention relates to a charging method and a charging device for a central air conditioner, in particular to a temperature difference equivalent charging method and a charging device for a central air conditioner of a constant air volume fan system. (2) Background technology: [0002] With the improvement of people’s living standards, central air-conditioning is widely used. Because the traditional billing methods of central air-conditioning are varied, there are major drawbacks, which are not conducive to energy saving and consumption reduction, and are not conducive to environmental protection and the long-term development of society. Therefore, the implementation of central air-conditioning Billing is imminent. In order to solve the problem of scientific and reasonable billing of central air-conditioning, relevant technicians have proposed various central air-conditioning metering devices and billing methods that are convenient for users. For ex...
