Method for electronically metering cold water consumption of heat pump hot water system

Abstract

The invention discloses a method for electronically metering cold water consumption of a heat pump hot water system. The method comprises the following steps of: 1, installing a liquid crystal display electronic flow meter or a voice broadcasting electronic flow meter on a water meter dial plate; 2, initializing data acquisition system software and initializing peripheral hardware; 3, registering, after the registration is successful, acquiring data of cold water inlet flow by a data acquisition system; 4, encrypting the data of the cold water inlet flow and transmitting a flow data code to a GPRS (General Packet Radio Service) network; and 5, transmitting the flow data code to a database and a WEB server, and transmitting to a remote monitoring terminal. According to the method, by adopting the electronic water flow meter, and combining with a communication system, the cold water consumption of the heat pump hot water system is remotely transmitted and monitored and recorded online, and online computing and historical data traceability of saved energy can be realized.

Description

technical field [0001] The invention relates to the technical field of heat pump hot water systems, in particular to an electronic metering method for cold water consumption in a heat pump hot water system. Background technique [0002] In the Twelfth Five-Year Plan, the Chinese government proposed to increase energy conservation and emission reduction, and promote green and sustainable economic development, and issued the "Notice on Accelerating the Implementation of Contract Energy Management to Promote the Development of Energy Conservation Service Industry (State Office [2010] 25 No)". The heat pump hot water system is required to have a higher energy efficiency ratio, at least 60% more energy-saving than the water heating system of a conventional electric boiler. Therefore, many energy-saving service companies adopt the method of contract energy management to transform the electric boiler hot water system to the heat pump hot water system. In the final energy saving s...

Problems solved by technology

However, the measurement method of mechanical water meters for cold water consumption has major defects. First, the workload of management personnel remains high. When calculating energy saving in each cycle, personnel must be sent to the site to read meters, which is time-consuming and labor-intensive. , so that the cost of use has been increasing for a long time; second, if the mechanical water meter is damaged, its historical data cannot be queried, which will bring difficulties to the energy-saving certification of both parties to the contract energy management
