Embodiment Construction

[0026] The principle and all embodiments of the present invention will be described in detail below.

[0027] The present invention takes any cooling / heating cycle system of the central air conditioner that can independently complete the work as a minimum billing unit to count the power of each internal unit in each minimum billing unit.

[0028] Such as figure 1 As shown, the central air conditioner of a specific embodiment of the present invention is multi-connected, which includes multiple cooling / heating cycle systems (system 1 to system n) that can work independently. Each system is a minimum billing unit, and two electric meters are set in each minimum billing unit: a first electric meter and a second electric meter. The first electric meter is connected with the outdoor machine of the minimum billing unit, and counts the electric quantity of the outdoor machine. The external machine may have a single-module structure or a multi-module structure. The second electric me...

Abstract

A method and apparatus for calculating electricity consumption for a central air conditioner, and a central air conditioner. The method for calculating electricity consumption for a central air conditioner comprises: taking a cold / thermal circulating system of a central air conditioner capable of completing work independently as a minimum charging unit, and acquiring state information of the minimum charging unit; in one charging period, collecting statistics about outdoor unit electricity consumption of the minimum charging unit by means of a first electricity meter, and calculating, according to the state information, outdoor unit electricity consumption that should be shared by each indoor unit of the minimum charging unit; collecting statistics about total electricity consumption of all indoor units in the minimum charging unit by means of a second electricity meter, and calculating, according to the state information, running electricity consumption and fixed standby electricity consumption that should be shared by each indoor unit; and adding the outdoor unit electricity consumption, the running electricity consumption, and the fixed standby electricity consumption that should be shared by each indoor unit to obtain electricity consumption needing to be borne by each indoor unit in one charging period. According to the technical solution, the structure is simple, and more accurate electricity consumption needing to be borne by an indoor unit can be obtained.

Description

technical field [0001] The invention relates to a central air conditioner, in particular to a method and device for more accurate calculation of its power consumption. Background technique [0002] The central air conditioner has multiple indoor units, and the operating conditions of each indoor unit are different, and the power consumption is also different. Taking multi-split as an example, multi-split is a category of central air-conditioning, and its "one-to-many" feature also has the problem of electricity bill apportionment. How to reasonably and fairly allocate the power consumed by the multi-connected system to each user has always been a difficult problem in the industry. How the billing system calculates the cost is also the focus of users. [0003] At present, there is no uniform billing method in the industry. The commonly used billing methods include area apportionment method, traffic apportionment method, and time appropriation method. The area apportionment ...
