Method for calculating central air-conditioning use proportion of each user

Abstract

The present invention relates to a method for calculating the central air-conditioning usage ratio of each user, which is applied to a central air-conditioning device, the central air-conditioning device is an indoor blower connected to each user, and defines a cooling / heating percentage parameter VW and A rated cooling / heating capacity parameter Wunit, when the indoor blower is started, detect the temperature difference ΔT between the outlet of the indoor blower and any place in the room, and multiply VW, Wunit, ΔT and the running time t of the blower to obtain a single The unit consumption Q of the central air-conditioning used by the user. In this way, the proportion of each user's use of the central air-conditioning can be calculated according to the unit consumption Q, which can be used as a fair billing basis for charging each user. The present invention can accurately calculate the proportion of each user using the central air conditioner, so as to fairly calculate the fee that each user needs to pay, has better accuracy, and can effectively save costs at the same time.

Description

technical field [0001] The invention relates to a calculation method, in particular to a method for calculating the central air-conditioning usage ratio of each user. Background technique [0002] With the prosperity and development of the social economy, there are many commercial buildings on the streets of today's cities. There are usually many company units in these commercial buildings, and there will be a large number of staff in the whole building. If the air conditioner is not turned on, it will take only a short Over time, the air quality will become very poor; however, if each room is equipped with an independent air-conditioning device, in addition to the huge installation cost, the power consumption is also very considerable. [0003] Therefore, most commercial buildings use central air-conditioning devices. Taking air-conditioning as an example, the central air-conditioning device produces cooling water and sends the cooling water to various company units. Circu...

Problems solved by technology

[0014] In order to solve the shortcomings of the current method for calculating the proportion of central air-conditioning use that is not accurate enough and the price of related matching equipment is too high, the main purpose of the present invention is to overcome the defects of the existing calculation method for the proportion of central air-conditioning used, and provide a new calculation method The method of the central air-conditioning usage ratio of each user, the technical problem to be solved is to make it possible to calculate the air-conditioning usage ratio of each user fairly, and without the need for high-cost equipment, so it is more suitable for practical use
