Air conditioner energy source charging method

Abstract

An air-conditioning energy charging method is applicable to computing consumption of each fan coil in an air-conditioning system. The method comprises a weight setting step, an operation amount computation step and a charge computation step. In the weight setting step, corresponding weights in different service modes are found according to the air exhaust specification of each fan coil, in the operation amount computation step, the state of each fan coil is detected at fixed intervals within a preset period and then the weights obtained at various time points are added to obtain the total operation amount of various fan coils in the preset period; and in the charge computation step, the sum of the operation amounts of all the fan coils in the air-conditioning system is divided by the total operation amount of various fan coils in the preset period, and the obtained result is multiplied by the total operation charge to obtain the operation charge of each fan coil in the preset period.

Description

technical field [0001] The invention relates to a billing method, in particular to an air-conditioning energy billing method. Background technique [0002] In modern buildings, central air-conditioning equipment has become a basic necessity like water and electricity. Existing central air-conditioning equipment usually has a chilled water main unit and fan coil units scattered throughout each floor. However, taking an office building as an example, each company has different commuting hours and prefers different air-conditioning strengths, resulting in The operating volume of each fan coil unit is also relatively different, and if the air-conditioning cost of each company is calculated by dividing the total operating cost of the building by the total number of companies (meaning average sharing), the company with less air-conditioning usage is more expensive than the burden. Many companies pay the same fee, which is obviously an unfair billing method. [0003] In order to ...

Problems solved by technology

[0005] Second, each flowmeter and temperature sensor needs to be wired separately to be electrically connected to the central control device and report the detected data. In the case of a large number of fan coil units, the complexity of the air conditioning pipeline will be increased , thereby increasing the associated maintenance costs

[0006] Third, if the air-conditioning pipeline of a building did not use this monitoring method as the basis of billing, if this monitoring method is to be introduced, all additional components, such as temperature sensors, flow meters, and corresponding power and communication cables, etc. It needs to affect the existing air-conditioning pipeline, and the construction is more complicated and troublesome. Not only will there be a risk of damaging the existing air-conditioning equipment, but it will also increase the cost of introducing this technology
