In order to reduce the runing time of circulating pump 30, to save power consumption, temperature difference controlling party is used in present embodiment Formula carrys out opening, stopping for control loop pump 30, heats the water in water tank and working media heat dissipation.Controller acquires second temperature sensing The detection signal of device 52, third temperature sensor 53, the detection letter based on second temperature sensor 52, third temperature sensor 53 The water temperature of water tank 20, the temperature of working media in collecting plate 10 are obtained number respectively, when the temperature and water tank of working media Water temperature difference when reaching the first heat exchange threshold value, controller manipulate the first solenoid valve 71 electric be turned on circulation, the second electromagnetism 72 power loss of valve keeps blocking circulation, and above-mentioned heating pipeline connection, working media can circulate in heating tube stream, controller behaviour Vertical circulating pump 30 electric must be activated, and heat the driving force for being formed in pipeline and making working media flow, and working media flows through heat exchanger 21 heat the water in water tank 20 by way of heat exchange, until the temperature and water tank 20 of the working media of collecting plate 10 The difference of water temperature is stopped when reaching the second heat exchange threshold value, or is stopped when the water temperature of water tank 20 reaches the first above-mentioned preset value, control Device manipulation 71 power loss of the first solenoid valve is closed blocking circulation, second solenoid valve 72 keeps power loss to be blocked circulation, and described adds Pipe line and heat dissipation pipeline are blocked circulation, and controller manipulation 30 power loss of circulating pump is stopped operating, and working media stops stream It is dynamic.So far, the process once heated to the water in water tank is completed.The first heat exchange threshold value is greater than the second heat exchange threshold Value, for example, as a kind of optional scheme, wherein the first heat exchange threshold value can be 10 DEG C with value, the second heat exchange threshold value can take Value is 3 DEG C.That is, when the difference of the temperature of the working media in collecting plate and the water temperature of water tank reaches 10 DEG C, it is above-mentioned The circulation of heating pipeline, circulating pump 30 is activated, and working media circulation heat exchanger heats the water in all water tanks；When in collecting plate When the difference of the water temperature of the temperature and water tank of working media is less than 3 DEG C, circulating pump 30 is stopped, and above-mentioned heating pipeline is blocked Circulation, working media do not circulate to heat water.Using temperature difference control mode, the fortune of circulating pump 30 on the one hand can be effectively reduced The row time saves electric energy；Another aspect temperature difference is bigger, and heat exchange efficiency is higher, when the operation of circulating pump 30 can be effectively reduced Between, further save power consumption.Repeatedly, the water in water tank is heated, water temperature ramps up.When the water in water tank When temperature reaches the first preset value, it will be appreciated that be to be not likely to produce any temperature value of scale, such as 65 DEG C, when working media temperature with For the difference of the water temperature of water tank when reaching the first above-mentioned heat exchange threshold value, controller will no longer manipulate heating pipeline circulation, not right Water in water tank is heated, so that it maintains the first preset value, to avoid generating on the inner wall and heat exchanger of water tank Scale.

Further, during above controller manipulates heating pipeline heating water, the controller also acquires second The detection signal of flow sensor 62, the detection signal acquisition water flow value based on the second quantity sensor 62.Work as working media Temperature and water tank water temperature difference when reach the first heat exchange threshold controller manipulation heating pipeline connection heating water process In, when water flow value, which is not zero, to be worth, i.e. when with water, controller manipulates the disconnection of heating tube roadlock and leads to user, suspends to storage Water in water tank is heated, and the closing of circulating pump 30 can be such as manipulated, and can also be manipulated the first solenoid valve and be blocked circulation, with pause Heat exchange water；When water flow value is zero, i.e., user's useless water when, then manipulate heating pipeline connection and continue to water tank Interior water is heated.So control can avoid the situation to form the heating of user side waterside, cause water more higher with water temperature, The ratio for needing ceaselessly to adjust hot water or cold water, brings inconvenience.During above-mentioned pause heat exchange water, if work When making the temperature of medium higher than the second above-mentioned preset value, controller manipulates heat dissipation pipeline circulation, and working media flows through radiator Cooling stops when the temperature of working media is lower than the second preset value, stops when preferably dropping to following third preset values, favorably Opening, stopping number for circulating pump 30 is reduced, manipulation heat dissipation pipeline blocks circulation, stops heat dissipation；Second preset value can be regarded as thermal-arrest Working media permitted maximum temperature when plate works normally.So control, can collect to avoid working media because of high-temperature gasification High pressure is formed in hot plate, collecting plate is caused to damage, or even explosion.

During stopping heat exchange when the water temperature of above-mentioned water tank 20 reaches the first preset value (such as 65 DEG C), it is Avoid working media because high temperature damages collecting plate, when the water temperature of water tank 20 reaches work in the first preset value and collecting plate 10 When making the temperature of medium higher than the second above-mentioned preset value, the second preset value is greater than the first preset value, for example, as a kind of optional Scheme, the second preset value can value be 115 DEG C, the first preset value can value be 65 DEG C, expression do not generate the preferable of scale Temperature, can be effectively prevented from the sediment incrustation on 20 inner wall of water tank and heat exchanger 21, and controller manipulates the first solenoid valve 71 and loses Electricity remains turned-off blocking circulation, second solenoid valve 72 obtains electric-opening and forms circulation, and the heat dissipation pipeline forms the access of circulation, Controller manipulation circulating pump 30 electric must be activated, and under the suction driving of circulating pump 30, generation makes working media along heat dissipation pipeline The driving force of flowing, working media flow through radiator 40 and air heat-exchange along heat dissipation pipeline, and the temperature of working media is lowered, shape At the lower working media of temperature, the lower medium of the temperature flows back into collecting plate 10 through the suction of circulating pump 30, so recycles, Stop when the temperature of the working media in collecting plate reaches third preset value, controller manipulation 72 power loss of second solenoid valve is closed Impatency cutout is logical, 71 power loss of the first solenoid valve keeps blocking circulation, and the heat dissipation pipeline is blocked, and controller manipulates circulating pump 30 power loss stop motions, working media do not flow.So far, the process for once making working media radiate, the temperature of working media are completed Degree is reduced in safe temperature range, to avoid working media because high-temperature gasification forms high pressure in collecting plate, leads to collecting plate Damage, or even explosion, the advantageous service life for extending collecting plate.When the third preset value can be regarded as collecting plate normal work Any lower temperature value that working media is allowed, in order to reduce the number of starts of circulating pump 30, to save electric energy, third is pre- If value can value be slightly above the first preset value a certain value, for example, optional be higher than 10 DEG C, if the first preset value value is 65 DEG C, then third preset value can value be 75 DEG C.
