The utility model provides a kind of scheme of circulating pump heat supply, adopts circulating pump to heat, and circulating pump is the circulation fluid pump of carrying reaction, absorption, separation, regeneration of absorption solution, generally adopts centrifugal pump of single stage type.Circulating pump gets up the ducted hot water circuit of heating, and the heat of thermal source is sent to for thermal region.
Shown in Figure 1, the scheme of circulating pump heat supply of the present utility model is as follows: according to supplying thermal region outdoor temperature (atmospheric temperature) changing value in the scheduled time (as the time), and the required gross area value for thermal region, calculate the total load for thermal region, according to heat supply total load, circulating pump efficiency, heat-exchange system efficiency and supply backwater temperature difference, calculate a day quantity of circulating water, and further operation number of units and the day operation time of determining day circulating pump, and operation number of units and the running time of this day circulating pump the circulating pump of heating system is dispatched.In addition, be the heat supply more becoming more meticulous, also the above-mentioned scheduled time can be carried out to meticulousr division, as be divided into 12 periods (every 2 hours being a period), with day and night, carry out respectively heat supply planning (thermic load height period).
To have particular application as example, describe below: for summerday, the account form of thermic load is as follows: Q=Qmax (tn-t1)/(tn-t2) (GJ/h); Q is that outdoor temperature is the thermic load under t1; Qmax is heat supply network maximum heating load; T2 be outdoor heating accounting temperature (℃), as be-20 ℃ (district heating design code values); T1 be Heating Period outdoor temperature (℃); Tn be indoor design heating temperature (℃), as be 18 ℃ (national standards).
As within a scheduled time, the maximum temperature of the atmosphere of forecast is 0 degree, minimum-10 degree, and known mean temperature is-5 degree, following confession hot-zone is example: shopping centre 100,000 ㎡, design heating load is 70W/ ㎡; Residential quarter is 80 Wan ㎡, and design heating load is 50W/ ㎡; Factory district is 5 Wan ㎡, and design heating load is 70W/ ㎡, other relevant range 5 Wan ㎡, and design heating load is 90W/ ㎡.Can further calculate for the above-mentioned hot-zone that supplies, the thermic load per hour of this circulatory system is 121.1GJ (lucky burnt), whole day thermic load is 2904GJ, the situation that the supply backwater temperature difference of take is 40 degree is example, according to day heating heat Calculation formula: Q=cm (tx-ty), Q=quantity of circulating water * specific heat of water holds * (supply water temperature-return water temperature), wherein, c is that specific heat of water holds, and is 4.2 * 10
3every kilogram degree Celsius of joule, m is quantity of circulating water, and tx is supply water temperature, and ty is return water temperature.Can calculate thus a day quantity of circulating water m is 17285.71M
3.With an input pump flow 650M
3/ h, the circulating pump thermal efficiency 93% is example, its actual circular flow is 650M
3/ h * 93%=600M
3/ h, can calculate thus and learn that be 28.81h the running time of circulating pump every day.
For circulating pump day operation 28.81h, can adopt two circulating pumps, every operation 14.4h, to carrying out heat supply for hot-zone; Or adopt three circulating pumps, every operation 9.6h, also can meet heat demand.The time of simultaneously moving for circulating pump, may be selected in temperature lower time, as night (maximum period of thermic load).Take circulating pump running time as 28.81h be example, two circulating pumps at least will have the common running time of 5.31h, can be chosen in night two circulating pumps and jointly move 5.31h.
