It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, an embodiment of the present invention provides a method for controlling a wet film humidifier, where the wet film humidifier includes: a water storage container and a heater; the heater is arranged in the water storage container and used for heating the water in the water storage container;
the control method of the wet film humidifier comprises the following steps:
step S101: acquiring a current environment temperature value, a current environment humidity value and a temperature value of water in a water storage container;
step S102: determining a dew point temperature value according to the current environment temperature value;
step S103: and sending a control instruction to the heater according to the dew point temperature value, the temperature value of the water in the water storage container and the current environment humidity value.
When the ambient temperature is lower than the dew point temperature value, the relative humidity of the air is saturated, and the air cannot be humidified. Therefore, the embodiment of the invention provides a control method of a wet film humidifier, which is applied to the wet film humidifier. Referring to fig. 2, the wet film humidifier includes: the evaporator, the wet film, the water storage container and the heater arranged in the water storage container. According to the embodiment of the invention, the dew point temperature value is determined according to the current environment temperature value, and the control instruction is sent to the heater according to the dew point temperature value, the temperature value of water in the water storage container and the current environment humidity value, so that the water in the water storage container is heated in a low-temperature environment, the water temperature is increased, the humidification of the wet film humidifier can be started in any working environment with humidification requirements, the environment requirements of a data center are ensured, and the operation reliability of the data center is ensured.
In some embodiments, the wet film humidifier is installed in the humidification and dehumidification integrated machine, and the water storage container is a water receiving device during dehumidification.
The evaporator drips water during the refrigeration process of the air conditioner, so the air conditioner is generally provided with a water receiving device for storing the dripping water of the evaporator. In the embodiment of the invention, when the wet film humidifier is arranged in the humidification and dehumidification integrated machine, the water storage container and the water receiving device can be combined into a whole, the water dripping of the evaporator can supplement water for the wet film humidifier, and the water consumed by humidification of the wet film humidifier can help the water receiving device to drain water, so that the energy is saved, and two purposes are achieved at one stroke. Meanwhile, when the air conditioner is in a heating mode, the water temperature in the water storage container can rise in the heating mode, the heater is relatively energy-saving, and resources are saved.
In some embodiments, the wet film humidifier may further comprise: a water level switch and a water replenishing valve;
the water replenishing valve is arranged on the water storage container, is communicated with a water source and is used for replenishing water to the water storage container;
the water level switch is arranged in the water storage container and used for detecting the water level in the water storage container and controlling the switch of the water replenishing valve according to the water level in the water storage container.
When the water level switch detects that the water level in the water storage container is low, the water replenishing valve is automatically opened to replenish water, and the wet film humidifier is prevented from being lack of water and incapable of humidifying.
In some embodiments, the wet film humidifier may further include a water inlet pipe connecting the water storage container and the water source. The water replenishing valve can also be arranged on the water inlet pipe.
In some embodiments, the wet film humidifier may further include a temperature and humidity sensor for detecting a current ambient humidity value and a current ambient temperature value. In some embodiments, the temperature and humidity sensor may be disposed at a front end of the evaporator.

step S1033: and if the current environment humidity value is not greater than the preset humidity value, sending an operation control instruction or a closing control instruction to the heater according to the temperature value and the dew point temperature value of the water in the water storage container.
When the current ambient humidity has reached the requirement, no humidification is required, so the heater is turned off. When the current environment humidity does not meet the requirement and humidification is needed, the operation state of the heater is determined according to the temperature value and the dew point temperature value of the water in the water storage container.

When the temperature value of the water in the water storage container is smaller than the dew point temperature value, the air humidity reaches saturation and cannot be humidified, and at the moment, the heater is started to heat the water in the water storage container, so that the temperature is increased. When the temperature value of the water in the water storage container is slightly lower than the dew point temperature, the temperature to be increased is small, and the heater only needs low-power heating. When the temperature value of the water in the water storage container is lower than the dew point temperature value for a large amount, the temperature to be increased is large, and at the moment, the heater is started at high power, so that the temperature value of the water in the water storage container can be quickly increased.

if the operation mode of the humidification and dehumidification integrated machine is a heating mode, the temperature value of water in the water storage container is not greater than the dew point temperature value and not less than the dew point temperature deviation value, a closing control instruction is sent to the heater;
if the operation mode of the humidification and dehumidification integrated machine is a non-heating mode, the temperature value of water in the water storage container is not greater than the dew point temperature value and not less than the dew point temperature deviation value, a low-grade operation instruction is sent to the heater;
