Heating Design supply and return water temperature, outdoor calculate temperature are determined according to local heat supply design operating mode.
The utility model can effectively solve the problem existing in make-and-break time area-method.
1. when indoor heating system design is unreasonable, or user changes radiator rating or type privately, can cause actual radiator configuration not mate with design heating load.If still carry out heat sharing with original formula of sharing, those user's reality that can cause radiator area to surpass designing requirement are large with heat, share few, the actual few unjust phenomenon of paying the fees of heat.The utility model is by supply and return water temperature and the room temperature actual radiator area coefficient that can calculate user of actual measurement, thus revise radiator area change cause share heat error, it is more reasonable to make to share.
2. when heating system occurs hydraulic misadjustment or stops up, the too small user of flow can cause supply backwater temperature difference bigger than normal, and the same time of valve opening, it was few compared with other users under the same terms with heat.Now as still with original formula of sharing, carry out heat sharing and can cause that user's reality that these flows are little is few with heat, unjust phenomenons more than sharing that heat is many, actual and paying the fees.The utility model utilizes built-in correction shell script to calculate each user's temperature correction coefficient by supply and return water temperature and the outdoor temperature of actual measurement, thereby revise, due to what hydraulic misadjustment caused, shares heat error, makes to share more science of heat.
3. original heating system is to design on the basis based on continuous heat supply, and what use that heating system that make-and-break time area-method carries out heat metering adopts due to its temperature control is break-make mode, must cause customer flow to occur that step change type changes, will inevitably cause hydraulic misadjustment, the utility model is by supply and return water temperature and the outdoor temperature temperature correction coefficient that can calculate user of actual measurement, thereby revise, due to what hydraulic misadjustment caused, share heat error, make to share more science of heat.
Therefore 4. the utility model possesses the function of being closed and set user's temperature by host computer Long-distance Control user valve opening, can reach the effect that the user who stops heat supply to not paying Re Fei or application stops heat supply.When thermal source breaks down or occur that extremely severe cold weather cannot meet user's demand, can long-rangely turn down the design temperature upper limit of near-end user, guarantee the primary demand of heat supply network far-end disadvantageous inhabitant.
5. user can, according to the individual sexual demand of oneself, adjust indoor design temperature by room thermostat; According to the habits and customs of oneself and daily life rule, preset the control temperature of different periods in one day, realize and saving energy and reduce the cost, save the object of heat cost.
Room thermostat is arranged on the indoor exemplary position of living that needs control, and on-off controller and on-off valve are arranged on registering one's residence on pipeline of user.Unmanned or need turn down room temperature time in user family, the design temperature of room thermostat can be turned down, now room thermostat compares the actual room temperature recording and setting value at room temperature, if room temperature reaches setting value, room thermostat gets an electric shock and disconnects (or closed), by room temperature control circuit, to microprocessor, sends signal, microprocessor will be exported control signal, by on-off valve control circuit, on-off control valve is closed, stops heat supply, stop accumulating turn-on time simultaneously:
If room temperature is lower than setting value, the room thermostat closing of contact (or disconnection), sends for thermal signal to microprocessor by room temperature control circuit, and microprocessor will be exported control signal.By on-off valve control circuit, on-off control valve is opened, start heat supply, start to accumulate turn-on time simultaneously, and by corrected Calculation program, carry out certain correction according to the supply and return water temperature of measuring and outdoor temperature, and demonstration correction is opened ratio in real time, until reach design temperature, on-off valve is closed voluntarily again.Generally, in user family, nobody can turn down design temperature, and now the opening time of on-off valve will shorten, the object of can realize and save the energy, saving heat expense.In user family, there is people Shi Ke that the design temperature of room thermostat is heightened, now room thermostat is controlled this user's Heating State with new design temperature, positive and negative deviation 0.5 degree of the room temperature that makes this user in design temperature scope in, the heat demand that meets user, realizes heating according to need.This device possesses programmable functions simultaneously, user can set corresponding temperature by the different time periods according to the rule of life of self and actual needs every day, for example the work hours are 16 degree by Temperature Setting by day, get home 7 of every nights and be set to room temperature 18 degree at 7 can time, now room thermostat, by automatically controlling the room temperature of different periods, reaches energy-conservation object.
The above; it is only preferably embodiment of the utility model; these embodiments are all the different implementations based under the utility model general idea; and protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
