The existing indoor air is generally purified by installing a fresh air fan, and the fresh air fan can suck outdoor fresh air into the indoor space and discharge indoor old air to the outdoor space when working. Because the temperatures in four seasons are different, especially the temperature difference between the four seasons is large, the requirement for meeting the suitability of indoor temperature is a technical problem to be solved urgently.
In order to solve the problems, the existing fresh air fan is generally provided with a bypass area, when the fresh air fan is used in summer and winter, a bypass valve of the bypass area is disconnected, and fresh air needs to be cooled or heated through a heat exchanger; when the fresh air enters the fresh air suction area, the fresh air enters the fresh air discharge area, and flows into the heat exchanger. However, in winter and summer, even if outdoor air enters the room and passes through the heat exchanger, the outdoor air has a large influence on the indoor temperature, and the living comfort cannot be improved.
Among the new fan of current, what in addition set up a plurality of independent valves in the region of difference and control the circulation or the jam of different passageways respectively, but do not solve two seasons in winter and summer and influence great problem to indoor temperature, and a plurality of independent valves need set up respectively, and not only the structure is complicated, still can set up a plurality of regions of placing the valve, and occupation space is big. The valve is arranged in one cavity by the fresh air fan, the cavity occupies space, and the two valves are vertically arranged, so that the space is occupied.
Therefore, the position layout among the components and the structural design of the valve are very important for the space utilization rate, and on the basis of simple structure and reasonable space utilization, multiple operation modes are difficult to realize.

The real-time heat recovery efficiency of the heat exchanger can be calculated by integrating the temperature detection of the indoor temperature sensor, the outdoor temperature sensor, the exhaust temperature sensor and the fresh air temperature sensor. According to the detection information of the outdoor temperature sensor or the detection information of the indoor and outdoor temperature sensors, the action of the valve linkage mechanism can be controlled.
The working principle of the embodiment is as follows:
(1) when the outdoor temperature sensor detects that the outdoor temperature is higher than the set temperature (or the difference between the temperatures respectively detected by the outdoor temperature sensor and the indoor temperature sensor is higher than the set temperature), the control system controls the exhaust fan in the fresh air machine to stop and controls the motor to drive the valve linkage mechanism to act, namely, the motor controls the driving rod to rotate, one end of the driving rod drives the baffle plate of the valve plate to move towards the old air inlet side of the heat exchanger so as to block the old air inlet side of the heat exchanger and prevent the old air from entering from the heat exchanger; under the linkage effect, the other end of actuating lever drives the connecting rod and closes the tripe of new trend exhaust area air inlet department to prevent the new trend of heat exchanger output from flowing into new trend exhaust area. Under the power action of the fresh air fan, indoor air directly enters the fresh air exhaust area through the old air suction area, is filtered by the high-efficiency filter and then is exhausted indoors, indoor air circulation is achieved, and discomfort caused by large indoor and outdoor temperature difference is avoided.
(2) When the outdoor temperature sensor detects that the outdoor temperature is less than or equal to the set temperature (or the difference between the temperatures respectively detected by the outdoor temperature sensor and the indoor temperature sensor is less than or equal to the set temperature), the exhaust fan and the fresh air fan are started, and the control system controls the action of the valve linkage mechanism, namely, the motor drive rod rotates, and one end of the drive rod drives the baffle plate of the valve plate to move towards the direction far away from the old air inlet side of the heat exchanger, so that the old air can enter from the heat exchanger; under the linkage effect, the other end of actuating lever drives the connecting rod and opens the tripe of new trend exhaust area air inlet department for the new trend from heat exchanger output can flow into the new trend exhaust area. Therefore, the indoor air is discharged to the outdoor through the old air suction area, the heat exchanger and the old air discharge area in sequence, and the outdoor air is conveyed to the indoor through the fresh air suction area, the heat exchanger and the fresh air discharge area in sequence to carry out indoor and outdoor bidirectional circulation, thereby achieving the purpose of heat exchange.
(3) When outdoor wind power is large, after the new fan is shut down, wind can flow back into the room through the new fan through the new wind inlet. Because the fresh air outlet side of the heat exchanger and the air inlet side of the fresh air exhaust area are provided with the shutters, the shutters can be manually adjusted to be closed, and the outside air is prevented from being poured into a room through a new room system. It can be said that the tripe of this embodiment both can regard as preventing the use of irritating wind valve, also can regard as circulation valve to use, simplifies the structure greatly, practices thrift the cost, reduces occupation space.
