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, particularly provides a metering method for the power consumption of a multi-connected air conditioner indoor unit, and aims to solve the problem that an existing metering method is tedious to operate and large in deviation. The metering method comprises the following steps of calculating the real-time power NPim (t=k) of a draught fan of themth indoor unit and the standby power DPm (t=k) of an electric control panel based on running data of the mth indoor unit in the current unit period k; calculating the power consumption parameter NPm(t=k) of the mth indoor unit in the current unit period k based on the real-time power and the standby power; calculating the total power consumption parameter ZNPm (t=k) of the mth indoor unit in the current unit period k based on the power consumption parameter NPm (t=k) in the current period k and the power consumption parameter NPm (t=k-1) in the last unit period (k-1); and calculating the total power consumption ZNPm (t=k) of the mth indoor unit in the current unit period k based on the total power consumption parameter ZNPm (t=k) of the mth indoor unit. According to the metering methodfor power consumption of multi-connected air conditioner indoor unit, methods above are adopted without installing a plurality of electric quantity meters in the multi-connected indoor unit, thus being simple in operation and reducing the metering error.

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...
