When, wherein paddy section electricity price is the 50% of flat section electricity price, and crest segment electricity price is the 150% of flat section electricity price.In various electric heating modes,
Automatic temperature-regulator of the present utility model is both economical, and due to its can fully automatic operation, use cost also than relatively low,
Especially in northern China cold district, air energy heat pump efficiency comparison is low, so being more suitable for application of the present utility model.
The heat-accumulating process of heating system：Within the accumulation of heat period of setting, intelligent controller (or other intelligent electrics control member
Part) water in energy storage equipment 1 is heated by starting the electric heater 13 positioned at the bottom of energy storage equipment 1, when positioned at energy storage equipment 1
When the temperature sensor 12 on top detects water temperature and reaches setting value (such as 85 DEG C), controlled to stop electric heater 13 by temperature limiter 11
Heating, when water temperature is out of control, the bottom of energy storage equipment 1 install mechanical temperature limiter 11 act, by force stop heating.In accumulation of heat
Outside period, no matter how low water temperature is, and electric heater 13 all stops heating.
The exothermic process of heating system：High temperature heat transferring medium in intelligent controller startup water pump 7, energy storage equipment 1 is (such as
85 DEG C of water temperature), flowed out by upper diffuser 9, the low-temperature heat exchange medium flowed back by Automatic temp. adjusting valve 6 and with the delivery port of radiator 4
(such as 40 DEG C of water temperature) is mixed, high temperature heat transferring medium and low-temperature heat exchange medium automatic temperature-control, temperature adjustment in the presence of Automatic temp. adjusting valve 6
Heat transferring medium (such as 50 DEG C of water temperature) afterwards is through water pump 7, temperature-sensing valve 3, into radiator 4, after cooling through radiator 4, radiator 4
Backwater (such as 40 DEG C of water temperature) is divided into two-way, and high temperature heat transferring medium of the Automatic temp. adjusting valve 6 with being flowed out in energy storage equipment 1 is entered all the way and is mixed
Close, another road enters the lower diffuser 10 of energy storage equipment 1, and current slow down at once, and flow velocity is extremely low, disturb very little, exchanged heat with top
It is very low that medium mixes ginseng rate.The low-temperature heat exchange medium water temperature of backflow is low, and the high temperature heat exchange that its density is more than upper strata in energy storage equipment 1 is situated between
Matter.High temperature heat transferring medium and low-temperature heat exchange medium natural layering, form mesolimnion, with the continuous entrance of bottom backwater, top
High temperature heat transferring medium is continuously outflowed, and the upward piston-like flowing of bottom low-temperature cold water, mesolimnion is constantly raised, exchanged heat until by top
All replace in the space that medium takes.
In the utility model, intelligent controller has multistage clock setting function, and the paddy electricity accumulation of heat period can be set；Extremely trembling with fear
Weather, during the shortage of heat of energy storage equipment storage, can set the startup electric heater concurrent heating of ordinary telegram period.Therefore, intelligent controller
With regenerator temperature control function, regenerator temperature can be set according to Different climate, adjust amount of stored heat, reach the mesh for saving the energy
's.
