Honest and clean it is easy to the plurality of advantages such as bus extension and maintenance.
Cold-storage with let cool period, the moisture in cistern is three layers: cold water layer, mesolimnion, temperature (hot) water layer, counts
According to the when of collection, first temperature sensor is numbered according to order from top to bottom or from top to bottom, master controller
Read the temperature data of each temperature sensor, so can obtain the water of each layer in inflow temperature, leaving water temperature and pond
Temperature, thus to calculate anticipated required time, the accumulation of energy pond of having stored in the day accumulation of energy in accumulation of energy pond, accumulation of energy pond respectively pre-for master controller
Meter energy energization time,
Wherein calculate the accumulation of energy in accumulation of energy pond, ESC=V*1.163* η * t/P
In formula: ESC designs day pond accumulation of energy,
V accumulation of energy pond volume,
η cold-storage efficiency, relevant with storing groove structure, form, insulation situation, typically it is taken as 0.8～09,
The t water cold storage groove available Inlet and outlet water temperature difference, is recorded by temperature sensor,
P plot ratio, with tank structure, form is relevant, generally 1.08～1.3；
Calculating the anticipated required time that stored in accumulation of energy pond, calculating process is as follows:
Tr=(ESC-ESCTn)/(ESCTn-ESCTn+1)
In formula: pond accumulation of energy needed for ESC design day,
TrStored required time, by minute in units of,
ESCTnThis minute accumulation of energy total amount,
ESCTn+1Next minute accumulation of energy total amount；
