As shown in fig. 3, the control method of the humidification operation mode includes:
starting up, firstly judging according to a fresh air inlet temperature sensor: the fresh air inlet temperature T7 is more than 15 ℃.
If the fresh air inlet temperature T7 is higher than 15 ℃, the fresh air inlet temperature is not very low, and then whether the indoor relative humidity is less than or equal to 20% is judged; (1) if yes, the indoor is dry, then the system enters a powerful humidification mode, the indoor relative humidity is detected again after the system operates for a period of time in the powerful humidification mode, and when the indoor relative humidity is larger than or equal to 50%, the system automatically enters a common humidification mode for energy conservation; if the indoor relative humidity is still less than 50% after the normal humidifying mode is operated for a period of time, the super-strong humidifying mode is entered. (2) If the indoor relative humidity is not more than 20%, further judging the relative humidity RH7 of the fresh air inlet and the indoor set relative humidity RHSet; if the RH7 is less than RHSet-alpha%, starting the common humidification mode; and if the RH7 < RHSet-alpha% is not satisfied, the humidifying mode is not started. Alpha is a natural number.
The fresh air inlet T7 is not satisfied to be more than 15 ℃, and the super-strong humidifying mode is entered.
The following is a detailed description of the control procedure for the three humidification modes of the humidification apparatus of fig. 1:
and in a common humidification mode, wet film humidification or steam humidification is selected according to the difference between the fresh air inlet temperature T7 and the indoor temperature Tindoor. Specifically, as shown in fig. 4:
when | T7-Tindoor | is equal to or less than N ℃, N can be defined by user (for example, N is 1-5 ℃), it is shown that the difference between the temperature of the fresh air inlet and the indoor temperature is not large, and the temperature of the fresh air inlet is not very low, at this time, the wet film humidification is suitable to be started, water is supplied to the first water tank 10 through the water supply pipe 13 and the three-way valve 15, when the water level reaches a preset water level, the water supply system stops supplying water, then the electronic expansion valve corresponding to the refrigerant coil in the first water tank 10 is started, at this time, the heat pump system is in a heating mode, the refrigerant coil in the first water tank 10 is used as a condenser, heat is released to the water in the first water tank 10, and therefore, the water temperature is increased; then the water is absorbed by the corrugated wet film, when the fresh air passes through the surface of the wet film, the water on the surface of the wet film is evaporated and enters the fresh air, thereby realizing humidification.
When the temperature is not satisfied | T7-Tindoor | is less than or equal to N ℃, of course, T7 is less than or equal to Tindoor, which indicates that the difference between the fresh air inlet temperature and the indoor temperature is large, and the fresh air inlet temperature is low, at this time, the steam humidification is started (the steam humidification is isothermal humidification, and can ensure that the fresh air temperature does not continuously drop), water is supplied through the water supply pipe 13, and then the water is supplied to the second water tank 5 through the three-way valve 15, when the water level reaches a preset water level, the water supply system stops supplying water, then the PTC heater is started, the water temperature rises to 100 ℃ and becomes steam, the steam overflows through a large number of small holes in the surface of the arc-shaped circular pipe, and when the fresh air passes through, the steam is carried to enter a room, so that the humidification is realized.
And a powerful humidifying mode is used for the indoor environment working condition of extremely dry. As shown in fig. 5:
when the fresh air inlet T7 is more than 15 ℃ and the indoor relative humidity is less than or equal to 20%, the indoor humidity is low, and a user feels particularly dry and enters a powerful humidifying mode. The upper-stream fresh air fan is linked to operate at the highest rotating speed; then the water supply system starts to supply water to the second water tank 5, when the water level in the second water tank 5 reaches a preset water level, the water supply is stopped, then the PTC electric heater is started and operates at the maximum power, and after a period of operation; when the indoor relative humidity is detected to be more than or equal to 50%, automatically switching to a common humidifying mode; and if the indoor relative humidity is still less than 50% after the continuous operation for two hours, entering the super-strong humidifying mode.
The superstrong humidification mode is that the heating module of membrane humidification module and the heater 4 of steam humidification module are all opened, preferably open steam humidification module earlier and set for time later, open the heating module of membrane humidification module again.
Since the fresh air outlet temperature T9 is further reduced due to the humidification of the wet film, in a preferred embodiment, as shown in fig. 6, the heating module is a separately provided heat exchanger 19 for heating air.
The control module is used for controlling the heating module-heat exchanger 19 to have the maximum heating capacity when the super-strong humidifying mode is operated, and controlling the heater 4 of the steam humidifying module to be started when the internal temperature of the shell reaches a second temperature; the control module is used for controlling the heating quantity of the heating module-heat exchanger 19 according to the temperature of the fresh air outlet.
The following is a detailed description of the control procedure for the three humidification modes of the humidification apparatus of fig. 6:
and in a common humidification mode, wet film humidification or steam humidification is selected according to the difference between the fresh air inlet temperature T7 and the indoor temperature Tindoor. Specifically, the method comprises the following steps:
when | T7-Tindoor | is less than or equal to N ℃, N can be defined by user (for example, N is 1-5 ℃), it is shown that the difference between the temperature of the fresh air inlet and the indoor temperature is not large, and the temperature of the fresh air inlet is not very low, at this time, the wet film humidification is suitable to be started, water is supplied to the first water tank 10 through the water supply pipe 13 and then is supplied to the first water tank 10 through the three-way valve 15, when the water level reaches a preset water level, the water supply system stops supplying water, the electronic expansion valve corresponding to the heat exchanger 19 can be started simultaneously or discontinuously, at this time, the heat pump system is in a heating mode, the heat exchanger 19 is used as a condenser, heat is brought to the corrugated wet film through the fresh air, and when the fresh air passes through the surface of the wet film, water on the surface of the wet film is evaporated to enter the fresh air, so that the humidification is realized.
When the temperature is not satisfied | T7-Tindoor | is less than or equal to N ℃, of course, T7 is less than or equal to Tindoor, which indicates that the difference between the fresh air inlet temperature and the indoor temperature is large, and the fresh air inlet temperature is low, at this time, the steam humidification is started (the steam humidification is isothermal humidification, and can ensure that the fresh air temperature does not continuously drop), water is supplied through the water supply pipe 13, and then the water is supplied to the second water tank 5 through the three-way valve 15, when the water level reaches a preset water level, the water supply system stops supplying water, then the PTC heater is started, the water temperature rises to 100 ℃ and becomes steam, the steam overflows through a large number of small holes in the surface of the arc-shaped circular pipe, and when the fresh air passes through, the steam is carried to enter a room, so that the humidification is realized.
And a powerful humidifying mode is used for the indoor environment working condition of extremely dry. As shown in fig. 5:
when the fresh air inlet T7 is more than 15 ℃ and the indoor relative humidity is less than or equal to 20%, the indoor humidity is low, and a user feels particularly dry and enters a powerful humidifying mode. The upper-stream fresh air fan is linked to operate at the highest rotating speed; then the water supply system starts to supply water to the second water tank 5, when the water level in the second water tank 5 reaches a preset water level, the water supply is stopped, then the PTC electric heater is started and operates at the maximum power, and after a period of operation; when the indoor relative humidity is detected to be more than or equal to 50%, automatically switching to a common humidifying mode; and if the indoor relative humidity is still less than 50% after the continuous operation for two hours, entering the super-strong humidifying mode.
The super-strong humidifying mode is suitable for indoor environment working conditions that fresh air inlet temperature is low and indoor is extremely dry.
If the fresh air inlet T7 is not satisfied to be more than 15 ℃, the temperature of the fresh air inlet is low, and if wet film humidification is adopted, the fresh air outlet T9 is further reduced; if steam humidification is adopted, the temperature of the fresh air inlet is low, on one hand, the amount of water vapor contained in fresh air in unit volume is small, and on the other hand, when the temperature of the fresh air is too low and is mixed with high-temperature water vapor, condensation is easy to occur; therefore, the temperature of the fresh air is increased and then humidification is carried out. Therefore, the amount of water vapor contained in fresh air in unit volume can be increased, and the condensation risk can be reduced.
When the temperature of the fresh air inlet is lower, the humidifying effect can not be obviously improved even if the rotating speed of the upstream fan is increased and the power of the PTC is increased, and the amount of the contained water vapor is smaller because the air temperature is low. Therefore, when the temperature of the fresh air inlet is lower (for example, T7 is less than or equal to 15 ℃), the fresh air is heated by the heat exchanger 19 firstly, and the temperature of the fresh air is heated under the low-temperature working condition, so that the fresh air in unit volume can contain more water vapor.
As shown in fig. 7, entering the super-strong humidification mode, the electronic expansion valve of the heat exchanger 19 is opened at the maximum opening, and it is determined whether the temperature T8 inside the housing meets the requirement of being greater than or equal to 20 ℃ (for humidification after the fresh air temperature rises); if the temperature of the fresh air outlet T9 is larger than or equal to 25 ℃, the electronic expansion valve of the heat exchanger 19 is switched to the minimum angle, then the indoor relative humidity is judged to be larger than or equal to X% (more than 60% can be set), if the temperature is larger than or equal to X%, the steam is humidified-OFF, then whether the temperature of the fresh air outlet T9 is smaller than 20 ℃ every m minutes is judged, if the temperature is larger than or equal to X%, the electronic expansion valve of the heat exchanger 19 is switched to the maximum opening degree again, and the circulation operation is carried out again. The method can ensure that the temperature of fresh air supply is above 20 ℃, and simultaneously meets the requirement that the indoor relative humidity is above X%.
Of course, in some embodiments, two heating modules may be included, the first being a separately provided heat exchanger 19 and the second being a refrigerant coil disposed within the first tank 10.
In the common humidification mode, when the absolute fresh air inlet temperature-indoor temperature is less than or equal to N, the second heating module-refrigerant coil of the membrane humidification module is controlled to be opened, otherwise, the heater 4 of the steam humidification module is controlled to be opened.
The powerful humidification mode is that the heater 4 of the steam humidification module is switched on
The super-strong humidification mode is that the heat exchanger 19 and the heater 4 of the steam humidification module are turned on, and the control process is the same as that of the super-strong humidification mode shown in fig. 7.
According to the invention, the heat pump system, wet film humidification and steam humidification are combined together, and a certain control method is adopted, so that excessive water supply of the water supply system can be prevented, and the humidification effect and air supply comfort under the low-temperature working condition in winter can be ensured.
The advantages are that:
1) compare with ordinary wet film humidification, because the temperature of water promotes for the humidification effect is more excellent, and the air supply temperature can not obviously reduce, and the air supply travelling comfort is better.
2) The low temperature operating mode preferably rises fresh air temperature earlier, opens the steam humidification again, can guarantee the humidification effect and can guarantee the air supply travelling comfort again.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
