Multi-mode air conditioning equipment with total heat exchange, condensation dehumidification and air purification functions

Abstract

This invention provides a multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions, comprising: a housing; a total heat exchange core; an air filter module; a condensation dehumidification module; a fan module; an airflow switching module and an optical drainage module. This device can switch to "total heat exchange mode", "internal circulation dehumidification and purification mode" or "positive pressure protection mode" according to environmental needs, integrating the three major systems into a single unit, saving installation space, reducing energy consumption, and solving the problem of float ball jamming, achieving a three-in-one effect of ventilation, dehumidification and purification.

Claims

1. A multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions, comprising: a housing defining an internal accommodating space, the housing having an outdoor air inlet and an outdoor air outlet connecting to the outside, and an indoor return air outlet and an indoor air outlet connecting to the inside; a total heat exchange core disposed within the housing, having a separated and thermally conductive air inlet channel and an exhaust channel; an air filter module disposed within the airflow path of the housing for filtering suspended particles in the air; a condensation dehumidification module integrated within the housing, comprising a compressor, an evaporator and a condenser constituting a refrigeration cycle, wherein the evaporator and the condenser are disposed within the airflow path leading to the indoor air outlet; and a fan module disposed within the housing, comprising at least one supply fan and one exhaust fan for driving airflow. An airflow switching module includes at least one electrically operated damper disposed at a flow channel node, the electrically operated damper being controlled to selectively block or open the airflow path of the outdoor air inlet; and a control unit electrically connected to the fan module, the condensation dehumidification module and the airflow switching module; thereby, the device can switch between executing a total heat exchange mode, in which outdoor air is introduced and delivered indoors after heat exchange; and an internal circulation dehumidification and purification mode, in which outdoor air is blocked and only indoor air is circulated through the condensation dehumidification module and the air filter module.

2. The multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions as described in claim 1, wherein the device further includes an optical drainage module, the optical drainage module having an optical liquid level sensor disposed in a water collection tray below the evaporator and a drainage pump; the optical liquid level sensor includes a light emitting element, a light receiving element and a light guide prism, and uses the total reflection or refraction of light at the prism interface to detect the water level, and controls the opening and closing of the drainage pump accordingly.

3. The multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions as described in claim 1, wherein the outer structure of the housing is a flat cuboid, and the outdoor air inlet, outdoor air outlet, indoor return air outlet and indoor air outlet are located on one side of the housing, suitable for concealed installation in the ceiling of a building.

4. The multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions as described in claim 1, wherein the outer structure of the casing is in the shape of an upright column, suitable for indoor floor installation, and its internal airflow path is arranged vertically.

5. The multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions as described in claim 1, wherein in the total heat exchange mode, the control unit controls the electric damper to open the outdoor air inlet, the blower sequentially passes the outdoor air through the total heat exchange core, the air filter module and the condensation dehumidification module and then sends it out through the indoor air outlet, and at the same time the exhaust fan discharges the indoor air through the total heat exchange core through the outdoor air outlet.

6. The multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions as described in claim 1, wherein in the internal circulation dehumidification and purification mode, the control unit controls the electric damper to close the outdoor air inlet, the blower drives indoor air to enter through the indoor return air inlet, and after being filtered and dehumidified by the air filter module and the condensation dehumidification module in sequence, it is sent back to the room through the indoor air outlet.

7. The multi-mode air conditioning device with total heat exchange, condensation dehumidification and air purification functions as described in claim 1, wherein, Furthermore, it has a positive pressure protection mode. In this mode, the control unit controls the electric damper to open the outdoor air inlet and controls the supply fan to operate at a higher air volume than the exhaust fan, or stops the exhaust fan to create a positive pressure environment indoors.
