The water system can meet different temperature demands of users through water circulation. For the split equipment of the water system, in order to prevent frost cracking, an antifreezing flow is operated when the temperature is low. However, when cold water circulates through the entire water system, cold water outside the water system enters a room having a relatively high temperature, and thus, condensation water is easily accumulated inside the room. In order to solve the technical problem of indoor condensation ponding, a technical means of circularly heating the whole water system is adopted in the related technology, however, an anti-freezing process is operated to circularly heat the whole water system, so that energy is wasted.
Based on the above, the embodiment of the invention provides an antifreezing control method and device for a water system and related equipment.

the embodiment of the invention provides an antifreezing control method for a water system.
Fig. 1 is a schematic flow chart of an antifreezing control method for a water system according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a water system according to an embodiment of the present invention.
The anti-freezing control method of the water system provided by the embodiment of the invention can be applied to the water system, and the water system comprises the following components: and the valve is arranged on a communication pipeline of the inner machine and the outer machine.

and S1, triggering the valve to close under the anti-freezing heating process.
S2, controlling a heating device of the external machine to be started so as to promote the water temperature of the external machine side.
For example, in the case of a lower temperature, the water system may be set to automatically operate the antifreeze heating process. If it is determined that the antifreezing heating is needed, the valve is directly closed, the heating device of the external machine is triggered to work, and the water temperature of the external machine side is increased, so that the water temperature difference between the water temperature of the external machine side and the water temperature of the indoor side is shortened, the indoor side condensation ponding is reduced, the energy consumption for directly heating the whole water system is reduced, and the energy consumption is saved under the condition of reducing the indoor side condensation ponding.
In some embodiments, under the antifreeze heating process, triggering the valve to close includes: judging whether the indoor side needs to be freeze-proof; judging whether the indoor side has condensation risk or not when the indoor side needs to be freeze-proof; if the indoor side has condensation risk, the anti-freezing heating process is carried out.
For example, according to the antifreeze judging method in the related art, it is possible to judge whether or not the indoor side needs to be antifreeze, and when it is judged that the indoor side needs to be antifreeze, it is further judged whether or not there is a condensation risk in the indoor side, and if there is a condensation risk in the indoor side, the antifreeze heating process is entered, so that the antifreeze heating process can be entered as needed.
The method for determining the freeze protection in the related art may be to determine whether the indoor temperature is lower than a first freeze protection threshold, or determine whether the indoor temperature and the indoor water temperature are lower than a second freeze protection threshold, if so, it is determined that the indoor side needs to be freeze protected, which is not particularly limited in the embodiment of the present invention.
In some embodiments, further comprising: if the indoor side does not have the condensation risk, the valve is opened to enter the whole water circulation anti-freezing process.
For example, when it is judged that the indoor side is free of condensation risk, the valve can be directly opened, so that the whole machine water circulation anti-freezing process is started. The whole water circulation antifreezing flow is in the prior art, for example, the whole water system can be directly heated and circulated, and the embodiment is not particularly limited.
According to the antifreezing control method for the water system, provided by the embodiment of the invention, the indoor side and the outdoor side are distinguished, and the valve is arranged on the communication pipeline between the inner machine and the outer machine, so that under the antifreezing heating process, the valve is closed, the heating device of the outer machine directly heats the outdoor side, the water temperature of the outdoor side is improved, the water temperature of the outdoor side is similar to that of the indoor side, the antifreezing is carried out on the whole water system, the energy consumption for directly heating the whole water system is reduced, and the energy consumption is saved under the condition of reducing the indoor side condensation ponding.

For example, when the water system is provided with the dew point temperature calculation parameter acquisition device, whether the condensation risk exists or not can be judged through the dew point temperature value and the water temperature value of the water system, or whether the valve needs to be opened or closed is judged directly. Wherein the dew point temperature and temperature calculation parameter acquiring device may include: humidity sensor and bulb disposed inside the room. The dew point temperature calculation parameters may include: humidity phi and air temperature t. Dew point temperature value t d The calculation mode of (a) can be as follows:
dew point temperature value t d =aΦ+bt, wherein A, B is a coefficient, which can be set by a user according to actual requirements, and the embodiment of the present invention is not specifically limited.
In this embodiment, the water temperature value of the water system may be obtained according to the isothermal detection component such as the temperature sensing bulb or the temperature sensor. Wherein, the temperature detection component can be arranged on the communication pipeline at the indoor side; the device can also be arranged on a communication pipeline on the external machine side; the temperature detection assembly may be set at multiple points, so as to obtain a comprehensively calculated temperature value as a water temperature value of the water system, which is not particularly limited in this embodiment.

For example, the first preset temperature threshold may be 5 ℃, if the temperature of the water system is at least 5 ℃ higher than the dew point temperature value, it is indicated that there is no risk of condensation and water accumulation on the indoor side, and the valve is triggered to open to enter the whole water circulation antifreezing flow; if not, the risk of condensation and water accumulation on the indoor side is indicated, the valve is closed, and if the valve is in a closed state, the valve is not operated. In this example, the temperature of 5℃is merely exemplified, and the present invention is not limited thereto.
In some embodiments, after controlling the heating device of the external machine to be turned on, the method further comprises: acquiring an indoor environment temperature value, and judging whether the indoor environment temperature is lower than a first temperature threshold value; acquiring a water temperature value of the water system; if the indoor environment temperature is lower than the first temperature threshold, judging whether the water temperature value of the water system is at least higher than the indoor environment temperature value by a second preset temperature threshold; and if the water temperature value of the water system is at least higher than the second preset temperature threshold value of the indoor environment temperature value, triggering the valve to be opened.
In some embodiments, further comprising: and if the water temperature value of the water system is not higher than the second preset temperature range of the indoor environment temperature value, triggering the valve to be closed.
For example, when the water system is not provided with the dew point temperature calculating parameter acquiring device, whether the risk of condensation exists or not can be judged by the environmental temperature value of the indoor side and the water temperature value of the water system, or whether the valve needs to be opened or closed is judged directly. The temperature value of the indoor side may be obtained by a temperature detecting component disposed in the indoor side, which is not specifically limited in this embodiment. The water temperature value of the water system is obtained by referring to the water temperature value obtaining method of the water system described in the above embodiment, and the embodiment is not particularly limited.

In this example, the temperature of 5℃is merely exemplified, and the present invention is not limited thereto.

The auxiliary heating device may be an electric heating device, in this embodiment, a compressor heating device may be preferentially used, and when the compressor heating device fails, the auxiliary heating device is used for heating; or when the compressor heating device cannot meet the heating requirement, the auxiliary heating device is started to heat at the same time.
In some embodiments, the heating device comprises: a compressor heating device; the water system includes: a water pump; opening the valve, further comprising: the water pump gear and the working frequency of the compressor in the compressor heating device are improved.
When the water valve state needs to be changed from the closed state to the open state, the water pump gear position can be increased, and the working frequency of the compressor in the compressor device can be increased. The water pump gear can be lifted to the maximum, and the lifting amplitude of the frequency of the compressor is determined according to the number of the internal machines. For example, when only one internal machine is provided, the frequency is raised by 5Hz; lifting by 10Hz when 2-10 internal machines are used; and the frequency of the press is increased by 15Hz when the number of the internal machines is more than 10, and the upper limit of the frequency increase of the press can be set to be 15Hz.
In some embodiments, after the water valve is opened, in order to save steps and resources, a machine is not selected to judge whether the indoor side has condensation risk or not, so that the water temperature of the whole water system is rapidly increased.
