In determining a specific heating mode of the air-conditioning water system, it can be realized by the following preferred embodiments: calculating the temperature difference between the preset temperature of the indoor unit and the indoor environment temperature; if the temperature difference is larger than a first preset threshold value, executing an indoor heating and floor heating preheating mode; if the second preset threshold value is less than the temperature difference and less than or equal to the first preset threshold value, further judging whether the indoor surface temperature is greater than the indoor environment temperature; if yes, executing a floor heating and indoor unit air circulation mode; if not, executing an indoor heating and floor heating preheating mode; and if the temperature difference is less than or equal to a second preset threshold value, executing a heat preservation mode.

Based on the method, the opening of the water valve of the indoor unit, the wind gear of the indoor unit and the opening of the floor heating water valve which correspond to different temperature differences can be set in advance, the operation of the air conditioner water system can be accurately controlled after the temperature differences are confirmed, and rapid and efficient heating is guaranteed.
The second preferred embodiment is as follows: executing an indoor heating and floor heating preheating mode, comprising: calculating the opening degree X of the indoor unit water valve and the opening degree Y of the floor heating water valve according to the following formulas:
X＝aΔT+b；
Y＝cΔT×YMAX；
Wherein, delta T is the temperature difference, a, b and c are all preset values, Y MAX is the preset maximum value of the opening of the floor heating water valve, X is more than or equal to 0 and less than or equal to 100 percent, and 0.5Y MAX≤Y≤YMAX;
Determining a corresponding indoor unit wind gear according to the temperature difference; the corresponding relation between different temperature intervals and the wind gear of the indoor unit is preset; and controlling the operation of the air-conditioning water system according to the opening X of the water valve of the indoor unit, the opening Y of the floor heating water valve and the wind gear of the indoor unit.
Based on the method, the opening of the water valve of the indoor unit and the opening of the floor heating water valve can be accurately calculated, the wind gear of the indoor unit is confirmed, the operation of the air conditioner water system can be accurately controlled after the temperature difference is confirmed, and rapid and efficient heating is ensured.
The following is a detailed description: when the air-conditioning water system starts a heating mode, the preset temperature T 1 of the indoor unit, the indoor environment temperature T 2 and the indoor surface temperature T 3 are obtained. The indoor environment temperature refers to the temperature detected by an indoor unit wire controller or an indoor unit return air taste temperature bulb, and the indoor surface temperature refers to the temperature of a place 10cm above an indoor floor.
If T 1-T2 is more than 5 ℃, opening the water valve 1 of the indoor unit to 100%, operating the indoor unit according to a high grade, opening the water valve 2 of the floor heating to 10%, and performing primary preheating of the floor heating.
If T 1-T2 is more than 0 and less than or equal to 5 ℃, the opening of the water valve 1 of the indoor unit and the wind shield of the indoor unit are gradually reduced along with the reduction of the temperature difference, and the opening of the floor heating water valve 2 is gradually increased along with the gradual reduction of the temperature difference.
The opening of the water valve 1 of the indoor unit, the change of the wind level of the indoor unit and the opening of the water valve 2 can be realized according to the corresponding relation of the following table 1.
TABLE 1
More preferably, the adjustment can also be performed by a functional relationship as follows:
X＝aΔT+b；
Y＝cΔT×YMAX；
Wherein, delta T is the temperature difference, a, b and c are all preset values, Y MAX is the preset maximum value of the opening of the floor heating water valve, X is more than or equal to 0 and less than or equal to 100 percent, and 0.5Y MAX≤Y≤YMAX;
it should be noted that, in the process of executing the indoor heating and floor heating preheating mode, the temperature difference is monitored; if the temperature difference is reduced to meet: the second preset threshold value is more than or equal to the temperature difference and less than or equal to the first preset threshold value, and the indoor surface temperature is greater than the indoor environment temperature, the floor heating and heating mode and the indoor unit air circulation mode are switched.
2) Floor heating and indoor unit air circulation mode
It should be noted that the second mode needs to satisfy two conditions to enter: the temperature difference between the indoor environment temperature and the preset temperature of the indoor unit is smaller, and meanwhile the hiccup surface temperature is higher than the indoor environment temperature. After the air conditioner is started for heating, if the temperature difference is large, the air conditioner enters an indoor unit for rapid heating and floor heating preheating; if the temperature difference is smaller, the indoor unit can be heated first, the floor heating is quickly preheated (in this state, the opening of a water valve of the floor heating can be adjusted to be larger, the preheating time is shorter), and then the floor heating is performed after the floor heating is finished, so that no empty window period of heating can occur no matter the indoor temperature difference is large.
The preferred embodiment is as follows: executing a floor heating and indoor unit air circulation mode, comprising: and closing the water valve of the indoor unit, wherein the wind gear of the indoor unit is a preset low wind gear to circulate air, and the opening of the floor heating water valve is adjusted to be fully opened.
Based on this, when indoor earth's surface temperature is greater than indoor ambient temperature, indicate that warm up and preheat and accomplish, then warm up and heat and indoor set air cycle's mode smoothly transition to, under the state that satisfies indoor personnel's basic heating demand for most heat gathers in indoor lower part region, and the heat directly acts on the human body, promotes user's travelling comfort.
The following is a detailed description: after the floor heating preheating is finished, if the difference between the preset temperature of the indoor unit and the indoor environment temperature is smaller, the floor heating is switched to heating, and the indoor unit circulates indoor air. If T 1-T2 is more than 0 and less than or equal to 2 ℃ and T 3＞T2 is carried out in the running process of the air conditioning water system, the water valve 1 of the indoor unit is closed, the air level of the indoor unit is adjusted to be low air level, circulating indoor air is circulated, and the opening of the floor heating water valve 2 is opened to 100%.
In the process of executing the floor heating and indoor unit air circulation modes, monitoring the temperature difference; and when the temperature difference is reduced to be equal to a second preset threshold value, switching to a heat preservation mode.
3) Thermal insulation mode
It should be noted that, when no heat source is supplied in the room, hot air is collected in the upper part of the room, cold air is collected in the lower part of the room, and personnel activities are mainly concentrated in the lower part of the room. The collection point of indoor environment temperature is the middle part (wire controller) or upper part (indoor machine return air inlet) of the room, and the collection point of indoor surface temperature is the lower part of the room. In the heat preservation mode, the indoor surface temperature, the indoor environment temperature and the indoor machine preset temperature are kept constant, the temperature of the middle and lower parts of the room is guaranteed to be uniform and comfortable, the constant of the temperature of the indoor surface temperature, the indoor environment temperature and the indoor environment temperature is guaranteed to be achieved by adjusting the opening of the water valve of the floor heating, in short, the opening of the water valve is enlarged if the indoor surface temperature and the indoor environment temperature are lower, and the opening of the water valve is reduced if the indoor surface temperature and the indoor environment temperature are higher.
The preferred embodiment is as follows: performing a keep warm mode, comprising: controlling the indoor unit to stop heating, closing the water valve of the indoor unit and closing the floor heating water valve; and monitoring the indoor surface temperature and the indoor environment temperature, opening a floor heating water valve when the indoor surface temperature is smaller than the indoor environment temperature, and controlling the opening of the floor heating water valve to perform floor heating independent heat supply according to the magnitude relation among the indoor surface temperature, the indoor environment temperature and the indoor machine preset temperature.
Specifically, if the indoor surface temperature and the indoor environment temperature are lower than the preset temperature of the indoor unit, the opening of the floor heating water valve is increased; and if the indoor surface temperature and the indoor environment temperature are higher than the preset temperature of the indoor unit, reducing the opening of the floor heating water valve.
The following is a detailed description: when the indoor environment temperature reaches the set temperature, namely T 1≤T2, the indoor unit, the water valve 1 and the water valve 2 are closed. Meanwhile, the indoor surface temperature T 3 and the indoor environment temperature T 2 are detected in real time, and if T 3＜T2 occurs, the opening of the floor heating water valve 2 is adjusted in real time, so that T 1＝T2＝T3 is kept.
Based on the above, the method realizes the independent heating from the preheating of the floor heating to the heating of the floor heating and the air circulation of the indoor unit to the floor heating, saves the energy consumption and improves the comfort of users.
According to the invention, the water outlet temperature of the outdoor unit can be controlled in a higher water temperature state in the indoor heating and floor heating preheating stage, so that indoor rapid heating is ensured, the water outlet temperature of the outdoor unit can be reduced in the subsequent floor heating and indoor circulation stage and the indoor temperature heat preservation stage, on one hand, the problem that the opening degree of a floor heating water valve is always in a smaller opening degree range and is difficult to accurately control due to higher water temperature is avoided, and on the other hand, the load of the outdoor unit can be reduced and the energy is saved.
According to the invention, the water flow entering the indoor unit and the floor heating in the air conditioner water system is controlled through the preset temperature of the indoor unit, the indoor environment temperature and the indoor surface temperature, so that the indoor unit and the floor heating system are controlled to execute different control logics. The preheating of the floor heating system is finished while the indoor rapid heating is met, and compared with the existing heating scheme, the rapid heating time is shorter, and the comfort is better. Meanwhile, the problem that in the existing scheme, if the difference between the set temperature and the ambient temperature is smaller, the indoor heating speed is slower and the heating air window period occurs when the air conditioner water system directly performs indoor unit and floor heating combined heating or only floor heating. The invention can realize independent control of the single indoor unit without establishing communication between the indoor unit and the outdoor unit, is applicable to a two-unit water supply multi-unit system, can be used for a medium-and-large-sized central air-conditioning water system, and has wider application range and lower cost.
