Further, the device also comprises CO arranged outside the shell2Sensor, CO2The sensor is connected with the controller.
Further, the temperature control device also comprises an inner temperature sensor and an outer temperature sensor which are arranged outside the shell and outside the room, and the inner temperature sensor and the outer temperature sensor are connected with the controller.
Further, the heat exchanger is a paper core total heat exchanger.
Furthermore, the heat exchanger is of a square structure, the heat exchanger is obliquely arranged on the wall of the middle cavity of the air supply cavity and the air exhaust cavity, the part of the heat exchanger in the air supply cavity completely separates an air supply fan and an air return exhaust hole, an air exhaust filter is arranged on one surface of the heat exchanger facing the air return exhaust hole, the part of the heat exchanger in the air exhaust cavity completely separates the air exhaust fan and a switching hole, and the other surface of the heat exchanger facing the switching hole is provided with the air supply filter.
Furthermore, the inner wall of the shell is attached with a rubber heat insulation and sound elimination layer.
Furthermore, a filter screen is arranged on the air return inlet.
During operation, the controller controls the operation state according to requirements. In an indoor air circulation mode, the fresh air switching valve is closed, the return air switching valve is opened, the exhaust fan is not pneumatic, indoor return air is conveyed to the return air cavity through the return air inlet, is conveyed to the switching cavity through the return air switching valve, is filtered and conveyed to the air supply cavity towards the air supply filter through the switching hole with strong switching, and can be sent out by the air supply fan for condensation or direct sending; in the fresh air ventilation mode, the return air switching valve is closed, the rest valves and the motor are opened for operation, return air is conveyed to the exhaust filter through the return air exhaust hole to be filtered and conveyed, and is discharged through the exhaust fan through a flow of the heat exchanger, an upper inlet of the fresh air cavity enters fresh air, is conveyed to the switching cavity through the fresh air switching valve, is filtered and conveyed towards the air supply filter through the switching cavity, and is subjected to heat exchange with the return air through another flow of the heat exchanger and then is sent out through the air supply.
The paper core total heat exchanger with super-strong water absorption and humidification performances is adopted to realize the temperature exchange efficiency and enthalpy efficiency in the front of the industry. The interior of the heat exchange core body adopts a waffle structure, so that the air inlet and the air exhaust can be completely and fully exchanged by heat. The core material also has the antibacterial and mildew-proof functions, and is cleaner and more sanitary. The outdoor air and the indoor air are subjected to energy exchange, the polluted return air is discharged, the energy and the fresh air of the newly-fed outdoor air exchange heat to approach the indoor temperature instantly, so that the air is convenient to send out, a user experiences comfortable and healthy life, and the air conditioner has the advantages of intelligence, economy, energy conservation and environmental protection.
And aiming at the function of outdoor pollution, the air supply filter can effectively filter inhalable dust, smoke dust and the like of outdoor fresh air, so that a large amount of dust caused by windowing is avoided, outdoor air is effectively filtered, and the cleanness of the air entering the room is ensured.
