The present invention relates to the utilization of solar heat, particularly a kind of family expenses solar hot water system.
Background technology
At present, the family expenses solar hot water system of market sale is made up of solar water heater, control system and pipeline, adopts close-coupled solar water heater, because the water-heater water tank Capacity Ratio is bigger, in use has following problem: 1) clearance-type hot-water supply; 2) the water-heater water tank capacity is big, and in the sunshine deficiency, when using auxiliary heating, auxiliary heat time heating time is long; When 3) thinking the hot water of usefulness hot water and don't the whole water tank of needs, can not use a part of water heating wherein temporarily; 4) close-coupled solar water heater is an opening zero-pressure formula, and is smaller for top layer user heat hydraulic pressure, uses uncomfortable; 5) long as the hot water line, need bleed off the cold water in many pipes during with hot water earlier, both wasted water, inconvenient again.
Summary of the invention
The family expenses solar hot water system who the purpose of this invention is to provide a kind of 24 hours hot-water supplies is a main heat source with solar energy, and electrical heating is an auxiliary thermal source, can supply the domestic hot water in 24 hours.
The family expenses solar hot water system of a kind of 24 hours hot-water supplies, comprise the solar water heater, connecting pipe, control valve, circularly-supercharged pump, system's controller is characterized in that: be provided with main frame solar water heater 1 and subsidiary engine solar water heater 2, main frame solar water heater 1 water outlet of water tank c is connected with subsidiary engine solar water heater 2 water tank inlets by connecting pipe 3, and the water inlet a of main frame solar water heater 1 water tank is connected with water supply pipe with water inlet control valve 6 by water supply pipeline 4; The hot water that comes out from subsidiary engine solar water heater 2 water outlet of water tank b passes through hot-water line 5 circularly-supercharged pumps 7, water flow control valve 8 to water supply point 9 hot-water supplies, enters water supply pipeline 4 through circulation control valve 10 simultaneously; Temperature sensor 1a, breather pipe 1b, breather pipe 1c and level sensor 1d are housed on main frame solar water heater 1 water tank, electric heater 2a, temperature sensor 2b, breather pipe 2c are housed on subsidiary engine solar water heater 2 water tanks.
The family expenses solar hot water system of another kind of 24 hours hot-water supplies, comprise the solar water heater, connecting pipe, control valve, circularly-supercharged pump, system's controller is characterized in that: be provided with main frame solar water heater 1 and subsidiary engine solar water heater 2, main frame solar water heater 1 water outlet of water tank c is connected with subsidiary engine solar water heater 2 water tank inlet by connecting pipe 3; The water inlet a of main frame solar water heater 1 water tank is connected with water supply pipe by water supply pipeline 4, circularly-supercharged pump 7, water inlet control valve 6; The hot water that comes out from subsidiary engine solar water heater 2 water outlet of water tank b enters water supply pipeline 4 through circulation control valve 10 simultaneously to water supply point 9 hot-water supplies; Temperature sensor 1a, breather pipe 1b, breather pipe 1c and level sensor 1d are housed on main frame solar water heater 1 water tank, electric heater 2a, temperature sensor 2b, breather pipe 2c are housed on subsidiary engine solar water heater 2 water tanks.
The water capacity of above subsidiary engine solar water heater 2 water tanks is 40～60% of main frame solar water heater 1 a water tank water capacity; The delivery port c of main frame solar water heater 1 water tank is located at the bottom (side or following) of this water tank, the water inlet of subsidiary engine solar water heater 2 water tanks is located at the bottom (side or following) of this water tank, and subsidiary engine solar water heater 2 water outlet of water tank b are positioned at 3/4ths water level places of this water tank; Main frame solar water heater 1 cistern water level is higher than subsidiary engine solar water heater 2 cistern water level, and subsidiary engine solar water heater 2 water outlet of water tank b highly is lower than main frame solar water heater 1 water outlet of water tank C height, and the internal diameter of connecting pipe 3 is not less than 20mm; The work of last water control valve 6, circulation control valve 10, circularly-supercharged pump 7, electric heater 2a, temperature sensor 1a and 2b and level sensor 1d is subjected to 11 controls of system's controller, 12 is the circulation contact switch of system's controller 11, is installed in to use the water spot place away from system's controller.
At system shown in Figure 1, system's controller control mode is as follows:
The operation of 24 hours hot-water supplies: controller enters 24 hours hot-water supply running statuses, and when the water temperature in the subsidiary engine water tank was lower than serviceability temperature, the subsidiary engine electric heater started automatically; When reaching serviceability temperature, the subsidiary engine electric heater cuts out.Hot water in the main frame water tank enters hot water pipeline by the subsidiary engine water tank, and when the hot water in the main frame water tank had reached serviceability temperature and enters the subsidiary engine water tank, then subsidiary engine water tank electric heater did not start; When the hot water in the main frame water tank is lower than serviceability temperature and enters auxilliary water tank, the water temperature in the subsidiary engine water tank is descended, do not reach the use water temperature, then the subsidiary engine electric heater starts automatically.The subsidiary engine water tank is top water law water outlet, can hot water without interruption.
The regularly operation of hot-water supply: controller enters regularly hot-water supply running status, and regularly (one day can repeatedly) judges water temperature in the subsidiary engine water tank, when the water temperature in the subsidiary engine water tank is lower than serviceability temperature, starts the subsidiary engine electric heater automatically; When reaching serviceability temperature, the subsidiary engine electric heater cuts out.
Water in the system: during lack of water, last water control valve is opened automatically, enters moisturizing and moves in the main frame water tank, and after the main frame cistern water level reached 20-50% (can control), last water control valve was closed; When water temperature in the main frame water tank surpasses serviceability temperature, enter water running on the constant temperature automatically, promptly water temperature rises, and adds water, makes the interior water temperature of main frame water tank constant substantially, up to main frame water tank full-water level at once.When using hot water, main frame can be to the uninterrupted top of subsidiary engine water; After the hot water of preferential use solar energy heating used up, by last water, the hot water of extruding in the vacuum tube re-used, and improves system's solar energy utilization ratio.
Before hot water, click contact switch, promptly start circularly-supercharged pump and carry out the pipeline circulation, the existing hot water of tap of fetching boiling water during use, pump is in the dual-purpose state of a pump simultaneously, open with tap and promptly start the pump supercharging, to overcome water-heater water tank and hour to use very much uncomfortable deficiency with the water-head between the water spot.
In system shown in Figure 2, circularly-supercharged pump is to be contained on the water supply pipeline at circularly-supercharged pump 7 as last water supercharging and circulation dual-purpose pump with Fig. 1 difference, save water flow control valve 8, when last water, automatic ON cycle booster pump 7 is to solve the problem of tap water pressure deficiency.
With prior art relatively, advantage of the present invention is: these family expenses solar hot water system, be provided with two solar water heaters of main and auxiliaries, and can preferentially use solar energy and make full use of solar energy, system is realized Automatic Control.According to the hot water instructions for use, convertible hot water method of supplying as timing or not timing hot-water supply, can be guaranteed round-the-clock 24 hours hot-water supplies, and economical operation is reliable.
