Embodiment
Below in conjunction with accompanying drawing, power-supply metering system of the present invention is described further.
As shown in Figure 1, a kind of power-supply metering system for central air conditioner, comprises user's temperature controller 1a.....1n, fan coil on-off controller 2a.....2n, data acquisition counter 3, measuring control platform 6 and GPRS communication unit 7.Wherein, user's temperature controller 1a.....1n is for measuring user's indoor temperature, and recording user is for the setting of indoor environment temperature.Fan coil on-off controller 2a.....2n controls for carrying out the break-make of pipeline internal medium, and records duration of valve opening.Data acquisition counter 3 is for gathering the parameter of user's temperature controller 1a.....1n and fan coil on-off controller 2a.....2n, and by GPRS communication unit 7, parameter being transferred to measuring control platform 6,6 computational analysiss of measuring control platform also show user's detailed data.
User's temperature controller 1a.....1n is one by one corresponding to n user, and each user is at the indoor corresponding user's temperature controller of installing.User's temperature controller 1a.....1n comprises built-in temperature sensor and shows current room temperature and the temperature controller panel of user's design temperature, and temperature sensor can be measured indoor temperature and show on temperature controller panel.User can pass through the button design temperature of temperature controller panel.The comfort temperature that can be experienced according to self by user of design temperature is set voluntarily, is generally set as user oneself and feels comparatively comfortable temperature.User's temperature controller 1a.....1n carries out communication by wireless mode and fan coil on-off controller 2a.....2n.
Fan coil on-off controller 2a.....2n is corresponding one by one with user's temperature controller 1a.....1n, is arranged on fan coil front end.Fan coil on-off controller 2a.....2n has control and arbitration functions, is connected with the switch valve of fan coil, can according to the gap of indoor temperature and design temperature, control the switching of switch valve, to control the break-make of liquid media.In the present embodiment, the liquid medium of fan coil is according to setting season, such as being the liquid medium heating in winter, and is the liquid media of refrigeration in summer.When room temperature is during higher than user's design temperature, fan coil on-off controller valve-off stops fan coil heat interchange, and temperature is reduced gradually; When room temperature is during lower than user's design temperature, fan coil on-off controller Open valve carries out fan coil heat interchange and heats, until indoor temperature arrives and closes switch valve after the temperature of setting again and stop heating.When if indoor temperature is reduced to a certain degree (such as differing 0.5～1 degree Celsius with design temperature), fan coil on-off controller is controlled switch valve and is opened continuation heat supply, to maintain indoor temperature at design temperature.Fan coil on-off controller is controlled while opening switch valve, records the opening time of switch valve simultaneously, the parameter of calculating as heat cost.
Data acquisition counter 3 comprises that data acquisition unit 4 and energy share unit 5, and data acquisition counter 3 is wiredly connected to fan coil on-off controller 2a.....2n by MBUS agreement.The user data such as the user indoor temperature of the responsible collection fan coil on-off controller 2a.....2n of data acquisition unit 4 and user's temperature controller 1a.....1n, design temperature, duration of valve opening.Energy is shared user data that unit 5 gathers data acquisition unit 4 and according to user's valve opening rate, is carried out energy and share, according to user indoor temperature, design temperature, duration of valve opening, according to specific computing formula, each user of cumulative calculation is under the time of valve opening, the energy that temperature rise/fall expends to design temperature time, the energy that this user should share (concrete account form can referring to the < < make-and-break time area-method heat metering device technical conditions > > in Chinese architecture industrial trade standard).
Measuring control platform 6 gathers counter 3 by GPRS communication unit 7 connection data, and the usage data by user data and after sharing transmits and shows.The platform 6 of measuring control simultaneously can carry out Long-distance Control to fan coil on-off controller 2a.....2n by data acquisition unit 3, open and close switch valve, (as arrearage or building something unexpected happened) under special circumstances, keeper can directly control switch valve at measuring control platform 6, directly to control the break-make of user's heat supply.
Being appreciated that above-mentioned heat supply, is the heat supply of broad sense, also comprises the situation of cooling, by the liquid media in pipeline, is determined, is applicable to the situation of central heating or central refrigerating.In position, heat metering management platform can be arranged on the management end of whole heating system, with monitor whole system in each user's heat supply situation, in particular cases can also long-range direct control.
Power-supply metering system user temperature controller of the present invention is placed on indoor, for measuring indoor temperature and design temperature being set.User's temperature controller is connected with fan coil on-off controller by wireless mode, fan coil on-off controller automatic decision indoor temperature and user's design temperature, when room temperature is during higher than user's design temperature, fan coil on-off controller is closed switch valve and is stopped fan coil heat interchange; When room temperature is during lower than user's design temperature, fan coil on-off controller is opened switch valve and is carried out fan coil heat interchange.The basis that the duration of valve opening of the recording user of fan coil on-off controller meeting is simultaneously shared as heat cost.Data acquisition unit is connected with fan coil on-off controller by wired mode, gathers the parameter of each fan coil on-off controller by data acquisition unit; By energy, share unit and calculate user's cold and hot amount used.Data acquisition unit is connected with measuring control platform with data acquisition counter by GPRS communication unit, and measuring control platform is shown and remote controlled fan coil on-off controller user data.
Pass through technique scheme, user can set indoor temperature as required, system as sharing foundation, realized multiplex overcharge less by the object of few charge according to user's fan coil opening time, greatly improved the energy-conservation enthusiasm of user and the fairness of cold and hot amount expense allocation.
The above; for better case study on implementation of the present invention; not the present invention is imposed any restrictions, every any simple modification of above embodiment being done according to the technology of the present invention essence, change and equivalent structure change, and all still belong in the protection domain of technical solution of the present invention.
