Description
Technical field
The utility model relates to the antifreezing solar energy technical field, and relating in particular to a kind of single tube bidirectional solar that is used for the solar water supply freezing prevention tubing can winterization system.
Background technology
The outdoor temperature in winter is lower, and the solar water supply exposed tube is frozen stifled outside easily, even bursting by freezing can not use, and causes very big loss to the user.For solving above-mentioned frozen problem, three kinds of means to prevent freezings commonly used are arranged at present, be respectively electrical heating method, exhaust method and forced circulation method.Electrical heating method needs outside pipeline, to install heating tape additional, and power consumption is many like this, and the heating tape life-span lack, easy spontaneous combustion of long duration causes fire; Exhaust method is through the water emptying in the outdoor pipeline is prevented that pipeline from freezing, and this method causes significant wastage owing to will cause original heat to scatter and disappear the whole emptyings of the water in the outdoor pipeline; The forced circulation method is to make the water in the pipeline be in flow regime with water circulating pump, prevents waterborne freezing.Adopt now the winterization system of forced circulation method to be mostly the dual circuit circulation, because building exhaust duct space is limited, pipeline is installed inconvenience too much, and two-tube circulating water flow is big, and rapid heat dissipation has reduced the Heat-collecting effect of solar energy.
Summary of the invention
To the problems referred to above, the utility model provides a kind of single tube bidirectional solar of easy for installation, high insulating effect can winterization system.
Above-mentioned single tube bidirectional solar ability winterization system; Comprise water-circulating pipe, following water-circulating pipe and header tank; Last water-circulating pipe, following water-circulating pipe are connected with the solar water supply pipe through threeway, and the last water-circulating pipe other end is connected with the delivery port of header tank, and the following water-circulating pipe other end is connected with the water inlet of header tank; Also comprise the temperature sensor be located in the feed pipe and feed pipe lower end motor-driven valve by temperature sensor control; Following water-circulating pipe is being provided with magnetic valve near the header tank water inlet, and last water-circulating pipe is being provided with circulating pump near header tank delivery port place, and header tank upper limit water level place is provided with water level switch; Water level switch is electrically connected with magnetic valve, circulating pump, controls the break-make of both and power supply connecting circuit.The outer temperature sensor of feed pipe is responsible for detecting the outer real-time temperature of feed pipe, when temperature subcritical temperature (can be made as 0 ℃), opens motor-driven valve; Start winterization system; Water is along water-circulating pipe is toward dirty down, and the water in the assurance feed pipe is in flow regime, prevents to freeze.Be provided with header tank at following water-circulating pipe end; Collect the water that flows out, when treating that water level switch detects the water arrival upper limit water level in the case, connection circulating pump, magnetic valve are connected with power supply; Circulating pump work enters the water in the case in the feed pipe; The while closed electromagnetic valve, disconnection is connected with following water-circulating pipe, prevents to form interior circulation.When water level is lower than upper limit water level in the case, deenergization, circulation pump, magnetic valve is opened, and continues cyclic process down.

Magnetic valve described in the said apparatus is a normally open solenoid valve, and closed electromagnetic valve during circulating pump work only enters the water in the header tank in the solar water container, prevents circulation in the formation system.
Following water-circulating pipe in the said apparatus is provided with adjustable throttling, can regulate the flow of circulation down according to the outdoor temperature situation, and big flow is only arranged when temperature is low, when temperature is slightly high, flow is turned down, and it is too fast to prevent that heat scatters and disappears, the waste resource.
Cause scattering and disappearing of solar heat during winterization system work unavoidably, for giving the water additional heat in the solar pipe, electrothermal tube and temperature sensor can be set in header tank, temperature sensor is electrically connected with electrothermal tube.When water temperature is low, open the electrothermal tube heating, additional heat.
Establish heating tube in the header tank, form incrustation scale when water quality is bad easily and result in blockage, therefore, be preferably in down water-circulating pipe and be provided with water purifier, remove impurity in the water, also can play catharsis to the water in the solar energy simultaneously, magnetic valve is positioned at water purifier discharge water mouth place.
Above-mentioned heating means are applicable to the resident family of no heating installation in the family, but this method electricity wasting, for the resident family that heating installation is arranged in the family; Needn't take said method fully, heat exchanger can be set in header tank, the heat exchanger two ends are connected with caliduct; Carry out heat exchange, additional heat with the water in the caliduct.
The described winterization system of the utility model only starts the water circulation and prevents that pipeline from freezing when outdoor temperature is lower than setting value; Following water circulation is accomplished by natural drip; Need not other equipment, energy savings, and last water circulation greatly and the circulation of following water are all passed through a supply channel and are communicated with solar water container; Conserve space, the convenient installation; Be provided with heater or heat exchanger in the header tank, can be the water additional heat in the solar energy; This system also is provided with water purifier, removes impurity in the water, prevents to produce in the header tank dirt.This system bulk is little, does not take home room, and whole process full-automatic operation is easy to use.
