Embodiment Construction

[0053] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments as needed so as to adapt to specific applications. For example, although the specification is based on the total power consumption ZTH actually consumed by n indoor units, the total power consumption ZNH of the mth indoor unit within the current unit time period k is obtained m(t＝k) However, in the present invention, it is obvious that the total power consumption ZTH actually consumed by n indoor units can be replaced by the actual electricity fee of n indoor units, so that the electricity fee that each household needs to pay can be known. In other words, as long as the data obtained by this method ...

Abstract

The invention belongs to the field of air conditioners, and specifically provides a method for measuring the power consumption of internal units of multi-connected air conditioners. The purpose of the present invention is to solve the problems of cumbersome operation and large deviation in the existing measurement method. The measurement method of the present invention includes: based on the operating data of the m-th internal machine in the current unit time period k, calculate the The real-time power NPi of the fan m(t＝k) And the standby power DP of the electric control board m(t＝k) ;Based on the real-time power and standby power, calculate the power consumption parameter NP of the m-th indoor unit in the current unit time period k m(t＝k) ;Based on the power consumption parameter NP in the current unit time period k m(t＝k) and the total power consumption parameter ZNP in the previous unit time period (k-1) m(t＝k‑1) , calculate the total power consumption parameter ZNP of the m-th indoor unit in the current unit time period k m(t＝k) ;Based on the total power consumption parameter ZNP of the m-th indoor unit m(t＝k) , calculate the total power consumption ZNH of the m-th indoor unit in the current unit time period k m(t＝k) . Through the above method, the multi-connected indoor unit does not need to install multiple electricity meters, the operation is simple, and the measurement error is reduced at the same time.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a method for measuring power consumption of internal units of multi-connected air conditioners. Background technique [0002] A multi-connected air conditioner refers to a refrigeration (heat pump) system consisting of one or more outdoor units and multiple indoor unit systems installed in different application spaces. The multi-connected air conditioner system has been widely used in commercial and office places due to its advantages of saving installation space, high load energy efficiency, energy saving and environmental protection, and easy control and management. In commercial buildings, there are often situations where multiple users share one or more sets of multi-connected units, which requires the measurement of cooling / heating consumption by different users and the power consumption of the air supply operation of the internal unit in order to charge fo...
