A kind of embedded solar water heater
Technical field
The utility model relates to solar vacuum-tube water heater, relates in particular to a kind of embedded solar water heater.
Background technology
Solar energy vacuum tube water heater all is installed on the roofing in the market, can not be molten with roofing be one, influence overall aesthetics.And the water tank of solar water heater does not place indoor structure yet.
Summary of the invention
At above deficiency, the utility model provides a kind of embedded solar water heater, and heat collector and water tank adopt split-type structural, and heat collector is in light weight, can embed the roofing installation and the molten and one with roofing.
The technical solution adopted in the utility model is:
A kind of embedded solar water heater, it comprises heat pipe-type glass heat-collecting vacuum tube 1, the horizontal case 2 of thermal-arrest, mounting bracket 3, it is characterized in that this water heater also comprises attemperater 8, circulating pump 9, controller 4, low temperature, level sensor 7, pyrostat 12, between the horizontal case of attemperater and thermal-arrest by advancing, outlet pipe links to each other, circulating pump 9 is set on the water inlet pipe between two casees, attemperater 8 is connected with running water upper hose 10 and uses hot water feeding pipe 11, pyrostat 12 is positioned at the horizontal case 2 of thermal-arrest, low temperature, level sensor 7 is positioned at attemperater 8, controller 4 and low temperature, level sensor 7, the running water water supply valve 13 of pyrostat 12 and attemperater 8 links to each other.
Pyrostat 12 is positioned at the horizontal case 2 of thermal-arrest near the horizontal case outlet pipe of thermal-arrest 6 ports, and low temperature, level sensor 7 are positioned at the middle and lower part of attemperater 8.
Can be covered with cloche outside heat pipe-type glass heat-collecting vacuum tube 1, the horizontal case 2 of thermal-arrest and the mounting bracket 3.Attemperater 8 is indoor installing type water tank.
The advantage of the utility model solar water heater is:
Attemperater of the present utility model can place indoor, and the thermal-arrest partial volume is little, in light weight; Thermal-arrest is partially submerged into building, with the building one; Anhydrous in the vacuum glass heat collection tube, the breakage of vacuum glass heat collection tube does not influence the operation of system; Though increased circulating pump, cycle-index and heat-collecting capacity are proportional, and power consumption strengthens with heat-collecting capacity, and power consumption is few.
Because this solar water heater and building one, the roofing at dress heat collector place can put in a skylight, and can add on the heat collector and cover glass, to reach the purpose of daylighting and insulation; In also heat collector can being embedded on the wall or be hung on outward outside the balcony, attemperater is positioned within doors.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 3, solar vacuum-tube water heater of the present utility model, comprise heat pipe-type glass heat-collecting vacuum tube 1, the horizontal case 2 of thermal-arrest, mounting bracket 3, controller 4, the horizontal case water inlet pipe 5 of thermal-arrest, the horizontal case outlet pipe 6 of thermal-arrest, low temperature, level sensor 7, attemperater 8, circulating pump 9, upper hose 10, feed pipe 11, pyrostat 12 and water supply valve 13, its attemperater 8 is positioned within doors, water in the water tank is sent to the horizontal case 2 of thermal-arrest by the horizontal case water inlet pipe 5 of thermal-arrest by circulating pump 9, hot water in the horizontal case 2 of thermal-arrest is got back to attemperater 8 through the horizontal case outlet pipe 6 of thermal-arrest, attemperater 8 has upper hose 10 to be used for replenishing cold water in addition, also has feed pipe 11 to be used to export hot water.
This solar water heater can be embedded in the pit of roofing reservation, fixes by built-in fitting, and its attemperater 8 is positioned within doors, has reduced the weight that is installed in the external heat hydrophone.The heat collector of this solar water heater promptly can cover cloche outside heat pipe-type glass heat-collecting vacuum tube 1, the horizontal case 2 of thermal-arrest and the mounting bracket 3.Attemperater 8 can be indoor installing type water tank.
Horizontal case 2 of thermal-arrest and the 1 vertical setting of heat pipe-type glass heat-collecting vacuum tube, thermal-collecting tube 1 is inserted in the horizontal case 2 of thermal-arrest, the heat that absorbs is passed to water in the horizontal case 2 of thermal-arrest, water temperature in the horizontal case 2 of thermal-arrest raises, temporary transient heat accumulation, circulating pump 9 runnings after temperature raises, to attemperater 8, cold water enters into the horizontal case 2 of thermal-arrest with delivery.
Pyrostat 12 is positioned at the horizontal case 2 of thermal-arrest near the horizontal case outlet pipe of thermal-arrest 6 ports, and low temperature, level sensor 7 are positioned at the middle and lower part of attemperater 8.
When the temperature difference of the temperature of pyrostat 12 and low-temperature sensor 7 is higher than pump startup setting value (for example 10 degree) when above, controller 4 control circulating pumps 9 start, loop direction is by shown in figure one arrow: the cold water in the attemperater 8 is transported to the horizontal case 2 of thermal-arrest by circulating pump 9 through the horizontal case water inlet pipe 5 of thermal-arrest, hot water in the horizontal case 2 of thermal-arrest is got back to attemperater 8 through the horizontal case outlet pipe 6 of thermal-arrest, stop setting value (for example 3 degree) when following when the temperature difference of the temperature of pyrostat 12 and low-temperature sensor 7 is lower than pump, controller 4 is controlled circulating pumps 9 and is shut down.When low temperature, level sensor 7 detected attemperater 8 anhydrous (or water is discontented), controller 4 control running water water supply valves 13 were opened, and cold water replenishes and enters attemperater 8.
