Fig. 2 is the heating system structural schematic diagram of embodiment two.
Invention is further described in detail below in conjunction with the accompanying drawings.
Specific implementation mode
Embodiment one
Referring to Fig. 1, heating system includes heat storage water tank 7, circulating pump 8 and PTC electricity wall-hung boilers, heat storage water tank 7 and circulating pump 8
It is connected by water pipe.
PTC electricity wall-hung boilers include PTC calandrias 1, controller 2, temperature measurement probe 3, water flow switch 4, water inlet pipe 5 and go out
Water pipe 6.There is 1 inside of PTC calandrias the cavity for the perforation being in communication with the outside, water inlet pipe 5 to be connect with one end of PTC calandrias 1,
Outlet pipe 6 is connect with the other end of PTC calandrias 1, and water inlet pipe 5 and outlet pipe 6 are connected to the cavity of PTC calandrias 1, water from
It is flowed out from outlet pipe 6 after the entrance cavity of water inlet pipe 5 is heated.PTC calandrias 1 have there are six wall, and six walls constitute positive six face
A heating element is arranged on each wall for body structure, and each two heating element forms a heating unit, each heating unit
Heating power is different from other heating units, this allows for PTC calandrias 1 to have including stopping heating and three heating units one
Totally eight regulation power shelves including heating are played, are selected according to actual needs in available.Temperature measurement probe 3 and flow are opened
It closes 4 and is arranged at one end that PTC calandrias 1 are connect with water inlet pipe 5.Controller 2 and 1 split settings of PTC calandrias, i.e. the two are single
Solely installation, installation site is very flexible, is not integrated on a shell, will not mutually cause to restrict.Controller 2 is measured with temperature
Probe 3, water flow switch 4 and the heating element electrical connection on the wall of PTC calandrias 1.Temperature measurement probe 3 is used for surveying
Amount enters the temperature of the water of PTC calandrias 1, and measurement result is sent to controller 2, and controller 2 is according to temperature measurement probe
The temperature detected controls each heating unit.If the temperature measured is less than default (adjustable) temperature, controller 2 controls PTC
Calandria 1 increases power profile (totally eight regulation power shelves) by shelves and heats, until temperature reduces power with after default balance by shelves
Adjust shelves.If detecting the water temperature over-high in PTC calandrias 1, controller 2 controls PTC calandrias 1 and stops heating, when avoiding long
Between generate dry combustion method, play a protective role.Whether the flow that water flow switch 4 is used for detecting inflow PTC calandrias 1 is less than setting value,
And testing result is sent to controller 2, if being less than setting value, then it is assumed that flow into PTC calandrias 1 without water, controller 2 controls
PTC calandrias 1 stop heating, avoid causing dry combustion method, play a protective role.
One end of one end connection PTC calandrias 1 of water inlet pipe 5, the other end connect circulating pump 8, on water inlet pipe 5 access have more
A radiator 9.The other end of one end connection PTC calandrias 1 of outlet pipe 6, the other end connect heat storage water tank 7, on outlet pipe 6
Access has radiator 9.Arrow A in figure is water (flow) direction, and the hot water in heat storage water tank 7 flows into water inlet pipe 5 by circulating pump 8
In, hot water heat after radiator 9 distributes outward to heat, and water temperature reduces.After multiple radiators 9, significantly
The water for reducing temperature enters PTC calandrias 1, becomes hot water, hot water stream in outlet pipe 6 again after the heating of PTC calandrias 1
It is dynamic, flow back to heat storage water tank 7 after the radiator 9 on outlet pipe 6 fully distributes heat.Controller 2 is electrically connected with circulating pump 8.
Heat storage water tank 7 is provided with the auxiliary thermal 71 of electricity, and the auxiliary thermal of electricity adds the water in heat storage water tank 7 using Electric heating
Heat.In the present embodiment, heating system further includes solar thermal collector 10, and heat storage water tank 7 passes through water pipe and solar energy heating
The connection of device 10 forms closed circuit.Water in heat storage water tank 7 is heated using solar thermal collector 10 using solar energy simultaneously.
Access has expansion drum 12 on outlet pipe 6 between PTC calandrias 1 and radiator 9, and heat accumulation is being flowed into from solar thermal collector 10
Air bleeding valve 11 is provided on the water pipe of water tank 7.
PTC electricity wall-hung boilers switch is opened, equipment brings into operation, and recycles pump startup, and water flow switch, which detects, flows into PTC heating
The flow of body is greater than the set value, and temperature measurement probe 3 measures temperature and is less than preset temperature, and controller 2 controls PTC calandrias 1
Power profile heating is increased by shelves, until temperature reduces power regulation shelves with after default balance by shelves.PTC calandrias 1 directly concatenate
In the pipeline of heating system, the medium that hot reserve in pipeline has substantially reduced is directly heated, heat is replenished in time, greatly improves
Heating efficiency.
It is less than 6 degrees Celsius when temperature measurement probe 3 measures medium temperature, system can start circulating pump 8 and PTC calandrias
1,10 degrees Celsius of stoppings are heated to, system media frost hardening is prevented, gives PTC electricity wall-hung boilers necessary protection.When circulating pump 8
When failure or idle running, water flow switch can not detect flow, can prompt to cut off the water and can not start heating.When water flow switch failure causes
When PTC calandria dry combustion methods, PTC calandrias stop heating.PTC calandrias 1 are equipped with temperature detect switch (TDS), if controller 2 breaks down
Lead to dry combustion method, heating element reach a high temperature (such as 125 degrees Celsius) when, temperature detect switch (TDS) can put out screen power-off, and when recovery needs temperature control
Switch manual resets.If electric leakage ground connection occur in PTC calandrias, PTC calandrias can stop heating.
Embodiment two
The difference between this embodiment and the first embodiment lies in access has electric three-way valve 13, electric three-way valve 13 on outlet pipe 6
It is connect with circulating pump 8 by water pipe, electric three-way valve 13 passes through outlet pipe 6 and 1 one end of PTC calandrias and heat storage water tank 7 simultaneously
Connection, expansion drum 12 are arranged on the outlet pipe of connection electric three-way valve 13 and heat storage water tank 7, and the setting of air bleeding valve 11 is in connection three
On the water pipe of logical motor-driven valve 13 and circulating pump 8, without the solar thermal collector 10 described in embodiment one.When heat storage water tank 7 heats
Electric three-way valve 13 is oriented to heat storage water tank 7；If when 7 shortage of heat of heat storage water tank, electric three-way valve 13 gets around heat storage water tank 7, when
Line temperature is less than user's setting value, pipeline media flow, and PTC electricity wall-hung boiler will start supplying heat automatically, without storage
Boiler 7 heats.As long as heating system pipeline has media flow, so that it may which automatic heating, the entire process that controls is whole-process automatic, system
Energy saving in running and frame mode is simple.
