In practical use, the method described in this embodiment takes a house type in a building as an example, and we can separate the pipelines of the house type room, the living room and other areas according to actual requirements, and each area in fig. 2 is respectively provided with a human body infrared detection sensor, and the water outlet end of the pipeline in the area can also be provided with a temperature sensing bulb to detect the outlet water temperature of the pipeline in the area. And human body infrared detection sensors arranged in the regions detect whether people exist in the regions in real time.
As shown in fig. 4, if a human body infrared detection sensor installed in a living room area detects that a person is in the living room, a water valve in the area is controlled to be kept in an open state, and meanwhile, the temperature of water is detected through a temperature sensing bulb, so that the temperature of the outlet water is kept at T1 to ensure the normal heating quantity W1 (the normal heating quantity of the living room); if no person is detected in the living room, timing is started, whether the person is in the living room in 10 minutes (a first preset time period) is recorded, if no person is in the living room, the heating capacity is reduced to W11 (a first preset value) after 10 minutes, and the outlet water temperature is reduced to a T11 level; if the person comes from the middle, the timing is cleared, and the timing is restarted until no person exists again; if no one is left for 30 minutes (the second preset time period), the water valve is closed after 30 minutes, the heating quantity of the area is adjusted to 0, and the area is not circulated with water, namely is not heated.
If a human body infrared detection sensor arranged in a room area detects that a person exists in the room, the water valve in the area is controlled to be kept in an open state, meanwhile, the temperature of water is detected through a thermal bulb, and the temperature of the outlet water is kept at T2 so as to ensure the heating quantity W2 (the normal heating quantity of the room), because the room area is smaller than that of a living room, the room is relatively closed, the heat storage capacity is better, the normal heating quantity of the room is slightly smaller than that of the living room, T2 is less than T1, and W2 is less than W1; if no person is detected in the room, starting timing, recording whether the room is occupied within 10 minutes (a first preset time period), if no person is occupied, reducing the heating capacity to W22 (a first preset value) after 10 minutes, reducing the water outlet temperature to T22, and if the person is occupied in the middle, clearing the timing until the time is reset again; if no one is left for 30 minutes (the second predetermined period of time), the water valve is closed after 30 minutes, the heating capacity of the area is adjusted to 0, and the area is not circulated with water, i.e. is not heated.
Since the range of motion of people at home is generally concentrated in the living room and the room, the heating capacity of other areas does not need to be too high, as shown in fig. 5, if a human body infrared detection sensor installed in other areas detects a person, the water valve of the area is kept in an open state, the temperature of water is detected by the thermometer bulb, the outlet water is maintained at a temperature T3 which is a little lower than the normal heating capacity, the relative heating capacity is W3 (second preset value), i.e., T3< T2< T1, and W3< W2< W1. If no one is detected, the water valve of the zone is closed after 10 minutes (third predetermined time period), and the heating quantity of the zone is adjusted to 0, namely no heating is performed.
By dividing indoor areas, each area is provided with a set of heating control logic according to the attribute and the function of the area, the area of a living room is relatively largest, the heating capacity is largest, the area of the room is relatively smaller, the heating capacity is smaller, and the heating capacity is smallest due to the fact that the activity time of other areas is short. Therefore, the heating requirement is ensured, the electricity can be saved, and the purpose of saving more energy is achieved.
It should be noted that, the values of the first preset value, the second preset value, and the first predetermined time period, the second predetermined time period, and the third predetermined time period described in this embodiment need to be determined according to specific practical situations; the zone division can also be divided according to the specific house type of the building, and is not limited to living rooms, rooms and other zones.
In the present embodiment, a warm water unit is exemplified for illustration, and it is understood that the control method described in the present embodiment is also applicable to a cold water unit.
The control method described in this embodiment judges whether a person exists in the area by acquiring the human body infrared detection information of the area, and performs corresponding control on the water circulation system by combining the preset control logic of the area, so that the effects of reducing energy consumption and saving energy can be achieved.
