The heating system and the control method thereof of the present invention will be described with reference to fig. 1 to 3.
Specifically, the present embodiment provides a heating system including: the system comprises a heater 100, a solar water heater 200, a conduit 300, a first valve 400, an insulation can 500, a first circulating pump 800, a first temperature sensor, a second temperature sensor, a first liquid level sensor, a second liquid level sensor and a time module.
Specifically, the heater 100 includes a heat storage tank 110, and the heat storage tank 110 has a heat preservation function, and preferably adopts a heat preservation tank with an outer wall made of a heat preservation material.
Optionally, the heater 100 is a heating air-conditioning fan having a coil, a portion of the coil is located in the heat storage tank 110, and the heat storage tank 110 is filled with a heat conductive material.
When the air conditioner fan is not needed to heat, a certain amount of heat may be stored in the heat storage tank 110.
When the air conditioner fan is needed to heat, heat stored in the heat storage box 110 can be firstly adopted for supplying heat, when the air conditioner fan is used for heating, heat exchange is carried out between the heat in the heat storage box 110 and the coil pipe, and then the heat of the coil pipe is transferred to the environment through the fan.
Specifically, the solar water heater 200 refers to a solar water heater that is generally placed on a roof or the like at a position capable of receiving light and heats water by receiving ultraviolet rays. At present, the solar water heater 200 is mostly used for daily life water of people, such as bathing.
Specifically, the solar water heater 200 refers to a solar water heater that is generally placed on a roof or the like at a position capable of receiving light and heats water by receiving ultraviolet rays. At present, the solar water heater 200 is mostly used for daily life water of people, such as bathing.
Specifically, the solar water heater 200 has a water storage tank 210 for storing hot water heated by the solar water heater 200, the water storage tank 210 having a water outlet 211 and a water return 212;
generally, the storage tank 210 is located on the body of the solar water heater 200, and guides the stored hot water to a faucet through a water pipe.
The incubator 500 has a first water inlet 510 and a first water outlet 520, the duct 300 includes a first duct 310 and a second duct 320, the first duct 310 is connected between the water outlet 211 and the first water inlet 510, one end of the second duct 320 is connected to the first water outlet 520, and the second duct 320 is partially located in the heat storage tank 110.
In general, since the water storage tank 210 of the solar water heater 200 has a small capacity and is designed with reference to the amount of domestic water used by a user for bathing or the like, when hot water is directly supplied to one end of the heater 100, the amount of hot water in the solar water heater 200 is likely to be insufficient for other domestic water of the user.
In this embodiment, by arranging the insulation box 500, the hot water generated by the solar water heater 200 can be guided into the insulation box 500 for insulation storage, so as to increase the volume of the hot water prepared by the solar water heater 200, thereby satisfying the heat supply of the heater 100 and the daily water consumption of the user.
Specifically, the hot water in the water storage tank 210 is guided into the heat insulation box 500 through the first conduit 310, and since the height of the water storage tank 210 is usually higher than that of the heat insulation box 500, the hot water in the water storage tank 210 can flow directly into the heat insulation box 500 under the action of gravity. Alternatively, a circulation pump may be provided on the first pipe 310 to ensure that the hot water in the storage tank 210 is guided into the insulation can 500.
The hot water in the incubator 500 is heat-exchanged with the heat storage tank 110 through the second duct 320. Specifically, the water after heat exchange in the second conduit 320 may be directly discharged, or the other end of the second conduit 320 is connected to the water return port 212, the first circulation pump 800 is disposed on the second conduit 320, and the water after heat exchange with the heat storage tank 110 in the conduit 300 returns to the water storage tank 210 of the solar water heater 200 through the first circulation pump 800.
Preferably, the second pipe 320 is provided with a second valve 410 which is opened when the insulation can 500 is required to guide hot water to the heat storage tank 110 side and is closed when the insulation can 500 is not required to guide hot water to the heat storage tank 110 side.
The second pipe 320 is partially positioned in the heat storage tank 110, and the hot water in the insulation tank 500 exchanges heat with the heat storage tank 110 through the second pipe 320.
And the first temperature sensor is positioned in the heat insulation box 500 and used for detecting the temperature of the heat insulation box and sending the temperature to the control module.
The second temperature sensor is positioned in the water storage tank 210, is used for detecting the temperature of the water storage tank 210 and sends the temperature to the control module;
the first liquid level sensor is positioned in the heat insulation box 500, is used for detecting the liquid level height of the heat insulation box 500 and sends the liquid level height to the control module;
the second liquid level sensor is positioned in the water storage tank 210, is used for detecting the liquid level height of the water storage tank 210 and sends the liquid level height to the control module;
the time module is used for acquiring and recording a heat storage time value tx during the operation of the heat storage mode and sending the heat storage time value tx to the control module;
and the control module is in communication connection with the first temperature sensor, the second temperature sensor, the first liquid level sensor, the second liquid level sensor and the time module respectively.
Specifically, on the basis of the above specific implementation of the heating system, this embodiment further provides a control method of the heating system, as shown in fig. 2, including the following steps:
step S100, acquiring the temperature Tb of the incubator, the temperature Tc of the water storage tank, the liquid level height of the incubator, the liquid level height of the water storage tank and a heat storage time value tx during the heat storage mode operation, and determining the liquid level height ratio Hb of the incubator and the liquid level height ratio Hc of the water storage tank;
step S200, determining the opening and closing of the first valve 400 based on the heat storage time value tx and the preset time period t1 when the heat storage mode operates, and based on the temperature Tb of the heat preservation box, the temperature Tc of the water storage tank, the height ratio Hb of the liquid level of the heat preservation box, and the height ratio Hc of the liquid level of the water storage tank.
Specifically, when the heater 100 operates in the heat accumulation mode, the heater 100 may preset the heat accumulation mode, and when the user selects to turn on the heat accumulation mode, the heater 100 enters the heat accumulation mode, and the heat accumulation control is gradually performed in the heat accumulation tank 110. Preferably, the heat storage mode may be turned on following the turning on of the heater 100, but not turned off following the turning off of the heater 100, which means turning off a fan or the like, or turning off the heater 100.
In the heat storage mode, hot water is supplied into the heat-insulating box 500 through the solar water heater 200, however, the hot water prepared by the solar water heater 200 needs to satisfy daily water for bathing and the like of a user, and then, the heat is supplied to the heat-insulating box 500 by using redundant heat.
It should be noted that the heat storage time value tx during operation in the heat storage mode refers to a time value obtained in real time, and in the operation process of the heat storage mode, the heat storage time value tx is obtained every time when the control method described in this embodiment is executed once or every interval of time, including but not limited to the time value at the start time of the heat storage mode. The preset time period t1 refers to a time period during which a user uses hot water in the solar water heater during a peak period.
