We can recognize from the course of work of system mode one and principle, heat exchange mode of the present utility model is a kind of brand-new heat-exchange method, namely be different from Natural Circulation heat exchange or forced circulation heat exchange that existing market has been used, also be different from the displacement heat exchange that this patent people has proposed.So-called Natural Circulation heat exchange relies on the size of the water density that the water self-temperature just brings exactly, forms hot water upwards, and the heat exchange mode that cold water is downward, hot water are on top, and cold water is in the bottom; So-called displacement heat exchange is exactly the energy that relies on running water itself, displaces the hot water that has been heated to predetermined temperature in heat collector with the cold water that newly enters, and self is trapped in the cold water displacement of waiting in the heat collector next time.It is a kind of hot water that utilizes the energy that relies on running water to recycle first the part relative low temperature from heat storage water tank for heat exchange of the present utility model, be mixed into middle warm water with cold running water, warm water displaces the hot water that has been heated to predetermined temperature in the heat collector in using again, hot water enters in high temperature section upper hose or the heat storage water tank and stores, and middle warm water is trapped in the cyclic permutation of waiting in the heat collector next time.Therefore this is a kind of cyclic permutation heat exchange mode.In this heat exchange mode, because all be that warm water removes to displace the hot water that has been raised to predetermined temperature in heat collector in using at every turn, heat collector is the hot water that warm water is heated to predetermined temperature in the handle, rather than directly the hot water of cool water heating to predetermined temperature, heat the time of sending constant temperature hot water with regard to the decrease heat collector is each like this, that is to say this heat exchange mode, the time that hot water stops in the high temperature section upper hose is significantly shortened, the time of staying of warm water in the middle-temperature section upper hose in also shortening simultaneously.If after our understanding hot water was the Rapid Flow piping, although when flowing through pipeline, heat also can consume to some extent, so consuming people is acceptables, does not affect in other words overall situation.Because the pipeline of the overwhelming majority in the native system all is installed in indoor basically, if again water pipe being done some insulation processes, advantage of the present utility model, just fully embodied, on the basis that does not add any external energy, realize the long distance of heat collector and heat storage water tank, if water-level control apparatus and temperature and pressure control device all adopt frame for movement, then the utility model is realizing fully under the state of zero-power that the horizontal range between heat collector and the heat storage water tank reaches tens of rice far.For separated solar water heater, heat collector is installed in the south in house, and heat storage water tank is installed in hot water with the kitchen on the north, house of water spot and bathes the room and just becomes a reality.This is a kind of very large breakthrough for separated solar water heater, will very large facility be arranged to the popularization and application that separated solar water heater is installed.
Hence one can see that, adopts the advantage of cyclic permutation heat exchange to be, on the one hand can be in the heat storage water tank, and any hot water of relative low temperature reheats, and makes the water temperature of water tank more stable; The distance from the heat collector to the heat storage water tank on the other hand, significantly reduces the holdup time of hot water in water pipe, so that can prolong greatly.
Rotate the panel knob of Multifunctional switching valve to state two, A, C, D three interface Venturi types are communicated with, and namely the A interface is communicated with contraction section, and C interface is communicated with diffuser, and D interface is communicated with throat neck section; This status system is in uses hot water, and running water flows into the A interface by water pipe, produces negative pressure at the D interface place, and the constant temperature hot water of heat storage water tank is inhaled into D interface, and the running water that flows into the A interface is mixed into middle warm water and flows out from C interface.Because the hot water in the heat storage water tank is constant temperature hot water, by the mixing of Multifunctional switching valve, under metastable hydraulic pressure, the ratio of cold water and hot water is fixed.The water temperature that flows out from C interface so just can be the hot water of a suitable temperature, and because sneaking into of high-pressure cold water being arranged, the suitable temperature hot water of outflow also has a suitable discharge pressure, the similar water outlet pressurizing valve of Multifunctional switching valve this moment.If certainly require higher leaving water temperature or higher discharge pressure, the utility model does not repel electric control pump of serial connection in drainage pipeline, or by a pressue device water in the heat storage water tank is pressurizeed and to send.
Rotate the panel knob of Multifunctional switching valve to state three, A, B, C three interfaces are communicated with Wen's formula tubular type, and namely the A interface is communicated with contraction section, and B interface is communicated with throat neck section, and C is communicated with diffuser.It is emptying that this status system is in suction, and separated solar water heater just must be considered the preventing freeze in winter problem of heat collector and the pipeline that is connected because heat collector and part connecting pipe are installed in outdoorly.The utility model adopts the suction purging method, the course of work is such, when the panel knob forwards state three to, the running water that the A interface flows into, so that in B interface place generation negative pressure, B interface becomes negative pressure from the positive pressure of original state, the ducted pressure that is connected with B interface also becomes negative pressure from malleation, inlet pressure in the temperature and pressure control device is less than outlet pressure, the entrance and exit of temperature and pressure control device is connected, because the outlet of temperature and pressure control device is connected with the water inlet of heat storage water tank by the high temperature section upper hose, and heat storage water tank is communicated with atmosphere by ventilation mouth.B interface is all inhaled sky by the ducted water that the negative-pressure sucking handle is communicated with B interface thus, thereby finishes antifreeze.
Rotate the panel knob of Multifunctional switching valve to state four, A, D two interfaces are connected.This status system is in the Emergency water supply state, and what this state was considered is, do not have the sun in continuous many days, or the hot water amount in the water tank is few not enough, or the short time need to be with many hot water, and heat collector has little time the hot water that provides enough.In these cases, the rotary panel knob is to state four, running water from the inflow of A interface, do not pass through heat collector, be fed directly in the heat storage water tank by D interface, after cold water adds in the water tank, the interior water heating of electric heater feed-tank of directly installing with the satellite interface of heat storage water tank, that is to say this moment, separated solar water heater is taken as electric heater and uses.
The beneficial effects of the utility model are, a kind of brand-new separated solar water heater system, comprise the connecting pipe between heat storage water tank, heat collector, Multifunctional switching valve, temperature and pressure control device, water-level control apparatus and each parts, all string shape connections between each parts, system only realizes upper water heating heat exchange heat accumulation, supplies constant temperature hot water, preventing freeze in winter, emergent four kinds of duties of supplying hot water by a single mechanical panel knob-operated; System adopts a kind of brand-new cyclic permutation heat exchange, and the speed that heats is fast, heat exchange efficiency is high, in the zero-power situation, makes heat collector and the distance between the heat storage water tank can reach the decades of times of the corresponding distance of present separated solar water heater; Adopt single aqueous medium, direct heat transfer greatly reduces the cost of system.
