Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Caravan hot-water supply system embodiment
Be illustrated in figure 1 a kind of caravan hot-water supply system, this system comprises heat exchanger 5 and electric heater 6.The effect of heat exchanger is the temperature utilizing the temperature traverse of the refrigerant fluid flowed through to increase the water flowed through.Heat exchanger 5 comprises four ports, and wherein two ports are water inlet and water outlet, and flow into for cold water and hot water outflow, two other port is inlet and liquid outlet, for inflow and the outflow of refrigerant fluid.In order to electric heater 6 is easy to use, the voltage that electric heater 6 here uses is civil power 220V.Cold water utilizes the effect of pressure to flow into this system, and be divided into two-way cold water pipes by a T-pipe joint, one road cold water pipes is connected to the cold water input port in each wet part 8 in car, another Lu Weizhu cold water pipes 1, main cold water pipes 1 is divided into two-way by a T-pipe joint 3, wherein, one road cold water pipes is connected to the water inlet of electric heater by electric control valve 1, another road cold water pipes is connected to the water inlet of heat exchanger by electric control valve 24, the outlet conduit that the outlet conduit of the water outlet connection of electric heater is connected with the water outlet of heat exchanger is connected with main hot-water line 7 by a T-pipe joint, main hot-water line 7 is connected to the hot water input port in each wet part 8 in car.
Electric control valve 1 is for controlling the circulation of the water in electric heater 6, and electric control valve 24 is for controlling the circulation of the water in heat exchanger 5.Electric control valve 1 and electric control valve 24 can not conductings simultaneously, and when avoiding wherein having one not work in electric heater or heat exchanger, cold water and the hot water mutually mixed warm water formed do not meet and has a bath or other requirement.Such as: when electric control valve 1 and electric control valve 24 conducting simultaneously, now electric heater work, heat exchanger does not work, heat exchanger can not carry out not circulating in energy exchange or heat exchanger the refrigerant fluid of high-temperature, so the water of heat exchanger outflow or cold water, because the output of heat exchanger and electric heater is compiled in a pipeline, the hot water flowed out after electric water heater heating will be mixed into warm water by the cold water that heat exchanger flows out, the temperature of this warm water can not meet the normal temperature of having a bath, this not only can cause waste, and can not use hot water.
The exit end of pipeline circulated for the refrigerant fluid cooling engine 13 is connected to the fluid input port of fule heater 12, the pipeline that the fluid output port of fule heater 12 connects is connected a refrigerant fluid collection conduits 15 with the pipeline that circulation is used for the refrigerant fluid of cooling radiator 9 by T-pipe joint 11, this refrigerant fluid collection conduits 15 is connected to the inlet of heat exchanger 5 by electric control valve 4 14, the pipeline that the liquid outlet of heat exchanger 5 connects is used for the refrigerant fluid of temperature reduction again to flow through driving engine or radiator, driving engine or radiator are dispelled the heat again, circulate with this.On the pipeline of the refrigerant fluid of cooling radiator 9, electric control valve 3 10 is provided with in circulation.
Engine 13 or radiator 9 are operationally, the heat absorption that driving engine 13 or radiator 9 produce by refrigerant fluid, the temperature of refrigerant fluid rises, interchange of heat is carried out with the cold water of inflow heat exchanger in the refrigerant fluid inflow heat exchanger of high-temperature, the temperature of refrigerant fluid declines, and cold water temperature rises and becomes hot water.Electric control valve 3 10 is for controlling the flowing of the refrigerant fluid in radiator, and electric control valve 4 14 is for controlling the flowing of the refrigerant fluid in radiator and driving engine.
Fig. 2 is the control circuit figure of the several electric control valves in this hot-water supply system.What the control loop of the control coil of electric control valve 3 10 was connected in series is radiator switch 16, and when radiator switch 16 closes, when also namely radiator is devoted oneself to work, the control coil of electric control valve 3 10 obtains electric, and electric control valve 3 10 closes.When only having electric control valve 4 14 closed, the refrigerant fluid in radiator can carry out thermal exchange in heat exchanger; The control coil of the control coil of electric control valve 24, the control coil of electric control valve 4 14 and relay 18 is in parallel, form parallel line, heat exchanger switch 17 is connected with this parallel line, when heat exchanger switch 17 closes, namely during heat exchanger work, the control coil of the control coil of electric control valve 24, the control coil of electric control valve 4 14 and relay 18 obtains electric, electric control valve 24 and electric control valve 4 14 close, refrigerant fluid enters in heat exchanger and carries out energy exchange, cold water is become the hot water of high-temperature; What the control loop of the control coil of electric control valve 1 was connected in series is the normally closed contact of relay 18, when the control coil of relay 18 obtains electric, its normally closed contact disconnects, the control coil dead electricity of electric control valve 1, electric control valve 1 disconnects, and cold water can not flow through electric heater, only have when heat exchanger switch 17 disconnects, namely, when heat exchanger is not devoted oneself to work, electric control valve 1 just conducting, cold water can enter in electric heater 6 and be heated.This circuit can ensure that electric heater and heat exchanger can not work simultaneously, prevents the problem that cold and hot aqueous phase is mixed.
In above-described embodiment, the control form of the valve in system is electric control valve, as other embodiment, can also use the valve of other control forms, such as: manually-operated gate, can also comprise the electromagnetic valve of Non-follow control in manually-operated gate.
In above-described embodiment, electric control valve one is connected to the water inlet end of electric heater, and electric control valve two is connected to the water inlet end of heat exchanger, as other embodiment, electric control valve one can also be connected to the water side of electric heater, and electric control valve two can also be connected to the water side of heat exchanger.
In above-described embodiment, the pipeline of the refrigerant fluid of radiator and driving engine is provided with electric control valve, as other embodiment, this pipeline can not arranges valve.
In above-described embodiment, hot-water supply system comprises the delivery piping of the refrigerant fluid of radiator, as other embodiment, can not also comprise the refrigerant fluid delivery piping of radiator in hot-water supply system.
In above-described embodiment, give a kind of control circuit of electric control valve, use relay to carry out the switch control rule of valve in control circuit, as other embodiment, control circuit can also use intelligent controller as valve positioner, is carried out the switch control rule of valve by this controller.
In above-described embodiment, give a kind of laying structure flowing through the coolant duct of driving engine, fule heater and radiator, as other embodiment, concrete pipeline between driving engine, refrigerant fluid, heat exchanger is laid can also other forms, such as engine coolant circuit disclosed in the patent document provided in use background technology.
