Description
Technical field
It is water that the utility model relates to a kind of solar facilities defroster, especially circulatory mediator, and adopts direct forced cyclic type to solve the defroster that flows back to of preventing freeze in winter problem.
Background technology
Solar water heating system and solar heating system need to consider antifreeze problem when temperature may be lower than 0 ℃ area and uses in the winter time.To the system of outbalance, even also should consider antifreezing measures in the use of gentle area.
At present antifreeze mode commonly used mainly contains following four kinds in the engineering: flow back to antifreeze, that the anti-icing fluid circulation is antifreeze, the low temperature circulation is antifreeze, pipeline twines heating tape outward is antifreeze.
Flow back to antifreeze mode: when the systemic circulation pump is out of service, heat-transfer working medium just flows back to indoor heat storage water tank from heat collector and pipeline, be full of air in heat collector and the pipeline, avoid heat-transfer working medium to freeze, the purpose that the system that reaches is antifreeze, and the system of flowing back to has gone out to have antifreeze function and has also possessed anti-overheated function outward, when the heat storage water tank water temperature surpasses setting value, water pump is out of service, heat-transfer working medium refluxes, heat collector enters empty solarization state, and collecting system is heating water tank no longer, avoids water tank temperature to raise or seethe with excitement causing the damage of system unit.The main advantage that flows back to system is that the heating agent in heat collector and the pipeline is stored in the heat storage water tank night, need not waste solar energy at second day heats once more, and can select non-corrosiveness, heat transfer property preferably water as system's heat transfer medium, system effectiveness is higher, system's security of operation is stable, does not have extra energy consumption.The peak level that flows back to the system requirements solar heat storage water tank must be lower than the lowest water level of solar thermal collector, the installation that is heat storage water tank must be lower than heat collector, and the installation of solar energy pipeloop must be satisfied certain gradient, can be expelled back into out boiler fully to guarantee the water in the pipeline; The antifreeze mode of anti-icing fluid circulation, promptly the circulatory mediator in solar thermal collector and the system pipeline is an anti-icing fluid.Adopt the system of this antifreeze mode to be generally closed cycle indirect type system.The solar energy pipeloop does not have strict slope requirement, and antifreezing agent commonly used in the system is an ethylene glycol solution, but because ethylene glycol has corrosivity, should consider this point in the selection of system equipment.In system's running, circulatory mediator is that the system of anti-icing fluid has problems generations such as anti-icing fluid high-temperature evaporation, leakage, and in use, needs replenish interpolation to anti-icing fluid.
When heat collector itself does not have antifreeze the requirement, can adopt electrically heat tracing mode to carry out anti-freezing and heat-insulating, it is bigger to consume energy in moving and system, and has certain potential safety hazard.
In addition, it is antifreeze also can to adopt the mode of low temperature circulation to carry out, and promptly when environment temperature is low, the water circulating pump of unlatching collecting system washes away pipeline and heat collector in case the equipment bursting by freezing with the water in the water tank, and system's heat loss is bigger.
In sum, it is stable that employing flows back to the solar energy system security of operation of antifreeze mode, and there is not unnecessary energy consumption, the system that can guarantee freezes never, it is the optimal antifreeze mode of solar heating and hot-water heating system, but in the engineering practical application, bottom may not have the installation site of water tank, or be that conserve space directly is installed in heat storage water tank in the building ceiling, then system can not satisfy the heat collector that flows back to requirement and the difference in height of heat storage water tank, if it is antifreeze still to adopt the mode that flows back to carry out, then need to design, to satisfy the difference in height requirement of the system that flows back in the selection of system equipment and the aspects such as control of the method for operation.
