Description
The utility model relates to a kind of composite solar water heater, belongs to the solar water heater field.
The solar water heater that uses mainly contains at present:
(1) circular form water heater.
(1) natural cycle solar water heater.This water heater is to be power with the density contrast that temperature difference causes, carries out Natural Circulation, water pump need be installed just can produce hot water, but in order to produce enough motive forces, the thermal storage water tank must be higher than heat collector.For large-scale water heater,, all can bring some problems aspect building layout and the heavy burden because water tank is excessive.In addition, this water heater thermal efficiency is lower, and install at each family, multilayer residential building building, invests bigger.
(2) forced circulation formula solar water heater.This water heater uses water pump, and water is circulated between heat collector and thermal storage water tank, thereby the thermal storage water tank can be placed on the optional position, and pipe diameter can be smaller, and the installation fee of pipeline is cheap.Owing to circulate according to predetermined temperature difference, thereby the thermal efficiency is higher.But the time of taking hot water is just later.
(2) direct-flow type solar hydrophone.
This water heater cold water directly enters heat collector, its flow is controlled heat-obtaining water by the temperature sensor that is contained in the heat collector exit by controller function water pump (or magnetic valve), with the temperature of keeping outlet hot water in required boundary (general heat collector outlet water temperature begins to start 55 ℃-60 ℃ the time, stops about 50 ℃).Because cold water is to be pooled among the thermal storage water tank after the heat collector heating, this water heater does not circulate.Be characterized in that the thermal storage water tank needn't be higher than heat collector, make and install and be incubated easily.And the hot water among the thermal storage water tank has had enough temperature, and hot water can be taken at any time, takes other solar water heater of time ratio of hot water simultaneously and wants early.But the thermal storage water tank is comparatively heavy, gets warm spot when high, and the thermal efficiency is low, gets warm spot when low, and the water yield is big, and hot water can overflow in the thermal storage water tank, and warm water is no longer suitable in the cold slightly rear cabinet.
The purpose of this utility model is to overcome the deficiency of prior art and the composite solar water heater that has single flow structure and circulating structure and DC operation mode and the timesharing of periodic duty mode to carry out in a kind of compact conformation, thermal efficiency height, good, the same device of practicality is provided.
The utility model is achieved in that
Scheme one: this complex type solar water heater is made up of heat collector 8, controller 7, heat collector outlet pipe 6, thermal storage water tank 5, overfall (steam vent) 4, cold water oral siphon 2, heat supply water pipe 3, in order to make this water heater have the function of DC operation mode and endless form, between thermal storage water tank 5 lower end and cold water pipe 2, be provided with the circulation pipe 1 that is used for periodic duty, the water pump 10 that an end is connected with controller 7, the unidirectional non-return valve 9 that ends; On cold water pipe 2, be provided with the magnetic valve 11 that an end is connected with controller 7, at one end with in the controller 7 that heat collector cooling-water temperature sensor T1 is connected increased thermal storage water tank's cooling-water temperature sensor T2 and the thermal storage water tank's level sensor H that the control water heater is connected with thermal storage water tank 5 respectively with an end of direct current or endless form work.
Scheme two: this kind complex type solar water heater is by heat collector 8, controller 7, heat collector outlet pipe 6, the thermal storage water tank 5, overfall (steam vent) 4, cold water oral siphon 2, heat supply water pipe 3 is formed, in order to make this water heater have the function of DC operation mode and periodic duty mode, and can when hydraulic pressure is not enough, work, between thermal storage water tank 5 lower end and cold water pipe 2, be provided with unidirectional check (non-return) valve 12, the water pump 13 that one end is connected with controller 7, at one end with in the controller 7 that heat collector cooling-water temperature sensor T1 is connected increased thermal storage water tank's cooling-water temperature sensor T2 and the thermal storage water tank's level sensor H that the control water heater is connected with thermal storage water tank 5 respectively with an end of direct current and endless form work.
More than working media in the two scheme water heaters two kinds of types of flow are arranged:
1, the direct current type of flow.Be cold fluid from cold water oral siphon 2 after magnetic valve 11 or water pump 13 and unidirectional check (non-return) valve 12 enter heat collector 8 heating, in heat collector outlet pipe 6, inject from thermal storage water tank 5 tops.This moment, the circulating line 1 of thermal storage water tank bottom was ended by unidirectional check (non-return) valve 9, and working fluid is the direct current type of flow.
2, circulate mode.Be water in the thermal storage water tank 5 by the unidirectional check (non-return) valve 9 of water pump 10 warp let-offs to heat collector 8, do further heating after, inject from thermal storage water tank 5 tops through heat collector outlet pipe 6.This moment, cold water pipe 2 was ended by magnetic valve 11 or unidirectional check (non-return) valve 12, and working fluid is the mode of circulating.
More than the working method of two scheme water heaters have:
1, DC operation mode.The average water temperature of the each water intaking of DC operation mode is to satisfy the lower bound of instructions for use (as being washed in 40 ℃-45 ℃).When anhydrous in the thermal storage water tank 5 (or water discontented), if heat collector 8 outlet temperature T1 exceed predetermined temperature range, by controller 7 control opens solenoid valve 11 or water pumps 13, making working media is the direct current type of flow.If when heat collector 8 outlet temperatures are lower than predetermined temperature range, close magnetic valve 11 or water pump 13, by cold water oral siphon 2.This process is to obtain the required hot water water yield.
2, one of periodic duty mode.After thermal storage water tank's 5 water are full, control opening and closing water pump 10 by controller 7 according to the predetermined temperature difference scope of heat collector 8 outlet temperature T1 and thermal storage water tank's water temperature T 2, the water level H in the thermal storage water tank no longer be completely till.The heat that this process is obtained heat collector 8 is used for further improving the temperature of hot water in the thermal storage water tank 5.
3, two of periodic duty mode.When the water (not necessarily full) that has in the thermal storage water tank 5 more than a certain amount of, and when water temperature T 2 is lower than desired temperature value (is 40 ℃ as shower) because of reasons such as heat radiations in the case, control the opening and closing of water pumps 10 by controller 7, water heater is worked in a looping fashion.The opening and closing of water pump 10 both can be carried out according to the temperature difference of heat collector outlet temperature T1 and thermal storage water tank's temperature T 2, also can carry out according to the predetermined temperature range that heat collector 8 outlets are reached.This process is to guarantee that the water temperature in the thermal storage water tank 5 is not less than desired temperature value.
More than three kinds of working methods, generally in the DC operation mode in advance, periodic duty mode and DC operation mode are adjusted timesharing automatically and are carried out.
