Detailed description of the invention
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail:
Embodiment 1:
As shown in Figure 1, this example provides a kind of solar energy central supplying hot water intelligence control system, comprising:
Two solar thermal collector square formations, described solar thermal collector square formation is collected heat by solar thermal collector;
Two heat storage water tanks, described two heat storage water tanks are connected with the solar thermal collector of two solar thermal collector square formations respectively, and described two heat storage water tanks are all connected to running water water pipe;
A constant temperature water tank, described two heat storage water tanks are to this constant temperature water tank supplying hot water;
Air source heat pump, described air source heat pump is connected with constant temperature water tank with heat storage water tank respectively;
And, variable frequency water supply module, described variable frequency water supply module is connected with constant temperature water tank.
The hardware components such as this example comprises that two solar thermal collector square formations, two heat storage water tanks catchment, constant temperature water tank, three air source heat pumps and variable frequency water supply module; Described two heat storage water tanks are jointly to a constant temperature water tank supplying hot water, air source heat pump auxiliary heating, and frequency-conversion water supply system is realized backwater control.This example can adopt touch-screen control, and temperature and the water level value of the solar thermal collector, heat storage water tank and the constant temperature water tank that gather according to sensor, can realize the round-the-clock solar energy central supplying hot water intelligence control system with forced circulation mode.
Wherein, solar water heater is a kind of device that utilizes solar radiant energy by greenhouse effects, water to be heated.Greenhouse effects refer to because convection current, reflection loss reduce a kind of natural phenomena that energy accumulating, temperature are raise gradually.Greenhouse effects are called again hot case principle, and it is to realize accumulation of energy by a closed box that is stamped clear glass above.Sunshine sees through glass and enters in casing, is absorbed, and be subject to stopping of glass and casing to the energy of external reflectance and convection current by black surface, is retained in case, and the energy in casing constantly gathers like this, and temperature constantly raises, and even can reach 100 DEG C～200 DEG C.Utilizing the high temperature of building up to carry out heating water, is exactly solar water heater.Because solar water heater does not consume any conventional energy resource (coal, oil, natural gas, electricity etc.) in running, so people call it " not coal fired boiler " visually, the water circulation schematic diagram of solar water heater as shown in Figure 2.
After water heating in solar thermal collector, will realize circulation so that the water in storage tank is constantly heated with the cold water of storage tank the inside, conventional heat exchange method mainly contains three kinds at present: Natural Circulation, forced circulation and constant temperature delivery water circulation.
1) natural recirculating type: the feature of natural recirculating type is that storage tank must be installed in heat collector top above water just can carry out systemic circulation; Water in solar thermal collector is through solar radiation, makes water temperature increase, and density starts to diminish gradually, with in storage tank not by the water generates of solar radiation density contrast (or claiming gravitational difference, temperature difference), formed thermal siphon pressure head and slowly risen in heat collector.Warm water enters storage tank through pipeline (upper circular tube) is set, and the interior water that relative temperature is low, density is larger of storage tank slowly declines at the same time, supplements through pipeline (lower circulation pipe) inflow heat collector bottom is set.Like this taking the difference in specific gravity of water or claim thermal siphon pressure head as active force, and do not make the mode that water circulates be called Natural Circulation by external force.Its density contrast of the operation of natural recirculating type is larger, and the speed of circulation is faster, otherwise circulation is slower.This endless form can make the water in storage tank persistently overheating, and solar radiation stops, and circulation also stops gradually.
2) forced circulation formula: forced circulation is as the term suggests be to force the water in heat collector and storage tank to circulate by external force.Its feature is that the position of storage tank is not subject to the restriction of heat collector position, can arrange arbitrarily, can be higher than heat collector, and also can be lower than heat collector.It is by water pump, heat collector to be received to the water of solar radiation and the water of storage tank circulates, and the water temperature in storage tank is increased gradually.The forced circulation water heater often adopting on market is a kind of twice circulation Split type water heater, and heat collector packs special heat-conducting medium or anti-icing fluid into, circulates by circulating pump.This pump is controlled by temperature difference starter, in the time that the temperature difference reaches predetermined temperature, starts pump, circulates; During lower than predetermined temperature, pump is out of service.Hot water is to carry out heat exchange by the special heat exchanger in heat storage water tank, and this example has realized this kind of mode just.
3) constant temperature delivery water formula: what constant temperature delivery water formula was different from forced circulation is that it is not the concept of circulation, but by temperature controller, the water source pressure or the water source plus-pressure water pump that reach design temperature is transported in storage tank.Its feature is that water source arrives storage tank through heat collector, because not circulation is very simple again, just water is sent into storage tank after vexed solarization in heat collector, therefore, has people that this mode is called to single flow or direct flow fixed temperature release.The another feature of this mode is to use in the lump using water wisely effectively with the mode of temperature difference control formula forced circulation, the water tank capacity of constant temperature delivery water is generally larger, sometimes the water of the previous day does not run out, if do not heated up, water bled off in vain, if there is the mechanism of the temperature difference or forced circulation just this part water can be heated.
And solar water heater can be classified according to different situations: what solar thermal collector and heat storage water tank were integrated is called vexed solarization water heater; What heat collector and heat storage water tank were combined closely is called entirety (or compact) water heater; What heat collector separated with heat storage water tank is called heat of dissociation hydrophone.According to the difference of solar thermal collector structure, can be divided into vexed solarization water heater, flat water heater and vacuum tube (comprising all-glass vacuum tube and heat-pipe vacuum-tube) water heater; According to the circulation feature of solar energy heating working medium, can be divided into nature (passive) having circulation water heater, force (initiatively) having circulation water heater and DC water heater; According to working medium circulation number of times, have and can be divided into a having circulation water heater (direct circulation or single loop circulation) and secondary cycle water heater (indirect cyclic process or double loop circulation); The material difference using according to solar energy heating, can be divided into metal, glass and plastics three major types type.Press heat storage water tank liner material difference, can be divided into again stainless steel water tank, enamel cistern, rustproof aluminum alloy water tank, zinc-plated copper coin and plastic cistern etc.
Solar water heater also can be according to the service time of hot water, is divided into seasonal solar water heater (without auxiliary thermal source), annual solar water heater's (having auxiliary thermal source) and round-the-clock (having auxiliary thermal source and instrument for automatic control) of use solar water heater.In addition, solar water heater can also, according to whether pressure-bearing of system, be divided into non-pressure water heater (normal pressure) and pressure-loaded water-heater.This example has realized the round-the-clock all-glass vacuum tube type heat of dissociation hydrophone with forced circulation mode.
