VRV air conditioner prepayment comprehensive cost control system and energy-saving cost control method thereof

Abstract

The invention discloses a VRV air conditioner prepayment comprehensive fee control system which comprises an on-site monitoring part and a background monitoring part. The on-site monitoring part comprises a switch and a plurality of power utilization areas; each power utilization area comprises an intelligent gateway, a plurality of multi-user distribution boxes and a plurality of groups of VRV air conditioners; the background monitoring part comprises a switch, a monitoring computer, a management server and a UPS (Uninterrupted Power Supply); a background supervision system is arranged in the monitoring computer; and the background supervision system comprises a data acquisition and broadcast time service module, an electricity metering and allocation algorithm module, an air conditioner prepayment management module, an energy consumption monitoring and energy-saving control module and an equipment management and data security module. According to the design, the functions are more complete, remote parameter collection, remote electricity meter reading, outdoor unit electricity sharing, energy consumption monitoring, remote automatic control and prepayment management are integrated, and remote energy saving and intelligent control can be achieved.

Description

technical field [0001] The invention relates to the field of VRV air conditioner prepayment, in particular to a VRV air conditioner prepayment comprehensive fee system and an energy-saving fee control method. Background technique [0002] VRV air conditioning system is an advanced system that can control the cooling / heating agent circulation volume of the compressor and the cooling / heating agent flow into each indoor heat exchanger, and can timely meet the requirements of indoor cooling and heating loads; with VRV The wide application of air-conditioning systems and the collection of air-conditioning fees have become management difficulties for property managers. [0003] The traditional VRV air conditioner household prepaid system mainly involves the functions of VRV air conditioner household billing and charge management. The functions are few and relatively single. In addition, it also lacks functions such as energy consumption monitoring and centralized control, which le...

AI Technical Summary

Problems solved by technology

The area apportionment method is simple, convenient, and cost-free, but it is inaccurate and cannot meet the needs of users for billing rationality; the metering method has more or less defects, and cannot completely solve the problem of the rationality of air-conditioning metering charges ;Time measurement does not take into account the power capacity of different indoor units and the different power consumption of each gear state; energy measurement fully considers the user's actual consumption of air conditioning cooling (or heat), and the measurement accuracy is high, but the equipment investment is large and the cost is high. high, difficult to maintain
