The water temperature and water level being layered in water tank 2.
It is as follows using control method based on the electric control gear in said system and system:
User's heating control method:
After receiving heating signal, judge to be layered whether water level and water temperature in water tank 2 all reach water intaking preset value, fetch water
Preset value includes two parameters of temperature and water level, can be set as needed;
If water level or water temperature all do not reach preset value, do not start water pump, and alarm, as long as two strips have one not
Meet, then do not supply water, ensure user's water quality, it is of course possible to for temperature and water level indicating, filled in the indoor display of display
Display is put, if water level meets condition, and only temperature is not high enough, after user determines again, can provide water at low temperature;
If water level and water temperature all reach preset value, start water pump, and open three-way magnetic valve, if temperature at discharging condensate senses
The temperature that device receives is less than preset value temperature, then water is delivered to drainage pipeline by three-way magnetic valve, if temperature at discharging condensate sensor
The temperature received is higher than preset value temperature, then water is delivered to layering water tank by three-way magnetic valve;
During water intaking, if user actively cancels water intaking, water pump and three-way magnetic valve are closed;If it is layered water tank
Water level or water temperature are reduced to below water intaking preset value in 2, then close water pump, three-way magnetic valve and alarm, ensure water utilizing process
In quality;
It is layered 2 method for supplementing water of water tank:
Meet that intermediate water tank 3 send water to layering water tank 2 during following full terms, condition includes:Water temperature in intermediate water tank 3
It is less than threshold value more than threshold value, layering 2 water level of water tank;Water in intermediate water tank 3 is all delivered to layering water storage by each moisturizing
Case 2, that is, open water compensating valve, and water compensating valve is closed after time rating;
3 method for supplementing water of intermediate water tank:
Carried out after each completion layering 2 watering step of water tank, i.e., water compensating valve starts to judge after closing, if layering water storage
2 water temperature of case is less than threshold value, layering water tank 2 starts back water pump to 3 backwater of intermediate water tank, so can long-time regardless of
In layer water tank 2 in the case of water, the water for being layered water tank 2 is heated again, avoids wasting;If it is layered 2 water of water tank
Temperature is higher than threshold value, water source valve is opened, water source valve can be flow valve, can control in injection in water source to 3 moisturizing of intermediate water tank
Between water tank 3 amount;
1 heating means of heat collection unit:
If temperature is less than threshold value in subset hot channel 11, or is layered water level in water tank 2 and meets or exceeds upper limit value, then
Close circulating pump and circulating valve, be to close subset hot channel 11 at night to add when temperature be less than threshold value in subset hot channel 11
The passage of heat, avoids the heat in intermediate water tank 3 from distributing;Water level meets or exceeds upper limit value in layering water tank 2, then it represents that
Layering water tank 2 has stored full hot water, and reheating water can not be injected into layering water tank 2, if if open the circulation pump
Waste electric energy;
If temperature is higher than threshold value in subset hot channel 11, and is layered water level in water tank 2 and is less than upper limit value, then ON cycle
Pump and circulating valve.
