Detailed Description
The present invention will be more clearly and completely described in the following detailed description of the preferred embodiments in conjunction with the accompanying drawings.
Fig. 1 shows a novel temperature and humidity control system based on a total heat exchanger, which comprises: the air conditioner comprises a shell 10, an exhaust fan 20, a blower 30, a total heat exchanger 40, a fresh air coil 50 and a humidifier 60, wherein the exhaust fan 20, the blower 30, the total heat exchanger 40, the fresh air coil 50 and the humidifier 60 are positioned in the shell 10. The total heat exchanger 40 is located between the exhaust fan 20 and the blower 30, the exhaust fan 20 is used for exhausting indoor air, the blower 30 is used for sending outdoor air into the indoor, and the exhaust air of the exhaust fan 20 and the sending air of the blower 30 realize cold and heat exchange at the total heat exchanger 40. The fresh air coil 50 is located at an air outlet of the blower 30 and is externally connected with a refrigerant system, and the humidifier 60 is located at a lower air inlet of the fresh air coil 50.
In a traditional multi-split air-conditioning and total heat exchanger 40 system, a fan coil of the multi-split air-conditioning system is in charge of controlling temperature, and the total heat exchanger 40 recovers energy in exhaust air, pre-treats fresh air, sends the fresh air into a room, and finally mixes the fresh air with air supply treated by the multi-split air-conditioning system in the room. The system has the problems that the humidity cannot be controlled, and the air mixing point is not necessarily on the heat-humidity ratio line of a room due to the mixing problem of the preprocessed fresh air and the air supply of the fan coil, so that the temperature control cannot be accurately ensured in practice, and the indoor state point has more deviation. Therefore, it is contemplated to provide the fresh air coil 50 and the humidifier 60 on the basis of the total heat exchanger 40 to handle this additional fresh air load, so that the fresh air fed into the room can be handled. That is, when the temperature of the supplied air is still different from the indoor temperature after passing through the total heat exchanger 40, the temperature is balanced by heating or cooling the fresh air coil 50. Meanwhile, the humidity is balanced by humidifying the fed fresh air.
In order to more accurately control the temperature of the air fed into the room, the novel temperature and humidity control system based on the total heat exchanger further comprises a temperature sensor 70, and the temperature sensor 70 is used for detecting the indoor and outdoor temperatures and controlling the working state of the fresh air coil 50.
In addition, the novel temperature and humidity control system based on the total heat exchanger further comprises a brushless direct current motor 80, the brushless direct current motor 80 drives the blower 30 to rotate, and the temperature sensor 70 controls the working state of the brushless direct current motor 80. The brushless DC motor 80 can adjust the rotating speed according to the temperature sensor 70, thereby changing the speed of the fresh air passing through the fresh air coil 50 and further improving the temperature control capability of the system.
In order to better control the humidity of the air supplied into the room, the humidifier 60 is connected to an external water supply device, and an electric control valve 90 is installed between the humidifier 60 and the external water supply device.
In addition, the novel temperature and humidity control system based on the total heat exchanger 40 further includes a humidity sensor 100, and the humidity sensor 100 is used for detecting indoor and outdoor humidity and controlling the operating state of the electric control valve 90. That is, the opening degree of the electric control valve 90 is controlled according to the indoor and outdoor humidity conditions, thereby adjusting the humidification capability of the humidifier 60. The humidifier 60 in this embodiment is a wet film humidifier 60, and can more effectively handle the fresh air load.
Under the working condition of summer, the relative humidity of the outdoor fresh air is high, and the fresh air subjected to the temperature reduction treatment by the total heat exchanger 40 is subjected to temperature reduction and dehumidification treatment to be less than or equal to the dew point of an indoor isenthalpic line and is sent into the room. The specific process comprises the following steps: indoor air state parameters are obtained through the indoor temperature and humidity sensor 100, and an indoor air enthalpy value is determined. Outdoor air state parameters are obtained through the outdoor temperature and humidity sensor 100, and an outdoor air enthalpy value is determined. The output of the fresh air coil 50 is adjusted according to the indoor and outdoor enthalpy difference, the air outlet enthalpy of fresh air is less than or equal to the indoor air enthalpy, and fresh air load is prevented from being brought into the room.
In winter, the indoor air state parameters are obtained through the indoor temperature and humidity sensor 100, the outdoor air state parameters are obtained through the outdoor temperature and humidity sensor 100, the heating quantity of the fresh air coil 50 and the humidification quantity of the humidifier 60 are confirmed according to the indoor and outdoor temperature value difference and the air supply ratio of fresh air and indoor machines, the fresh air load is prevented from being brought into the room, and meanwhile the indoor humidity is maintained.
Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
