Electric quantity sharing method of multi-split central air conditioner

Abstract

The invention relates to the technical field of air conditioners, in particular to an electric quantity sharing method of a multi-split central air conditioner. The method aims at solving the problemthat an electric quantity allocation method of a billing system of the multi-split central air conditioner is not accurate enough. In order to achieve the purpose, on the basis of the power consumption of an air conditioning system and the power consumption and the electric quantity sharing coefficient of each user indoor unit which are obtained in all the time periods with different electric charge unit prices in one day, the shared electric quantity of each user indoor unit in each power consumption time period is obtained. According to the electric quantity sharing method, when the electricquantity of the multi-split central air conditioner is shared, the difference between the electric charge unit prices in different time periods and the difference between the electric quantity sharing coefficients of the user indoor units are considered fully, so that the obtained shared electric quantity of each user indoor unit in each power utilization time period is more accurate, and the actual power consumption condition of each user indoor unit can be reflected more really.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a power allocation method for a multi-connected central air conditioner. Background technique [0002] Multi-connected central air conditioner is a type of central air conditioner for users, commonly known as "one-to-many", which means that one outdoor unit is connected to two or more indoor units through piping. A primary refrigerant air conditioning system in the form of direct evaporative heat transfer. [0003] In the use of multi-connected central air-conditioning, the central air-conditioning billing system needs to bill the electricity charges of different users separately, and it involves the power sharing of the air-conditioning system. At present, the commonly used method is to use the ratio of the number of indoor units of the users. and running time to share the electricity of the air conditioning system. [0004] However, the set temperature of the air con...
