The signal of second specific embodiment of a kind of interior circulation heat recovery fresh air unit of the invention as shown in Figures 2 and 3
Figure, from unlike the first implementation method, this specific embodiment also between the first dividing plate 11 and second partition 12 and is located
The first air-valve 163 for opening and closing fresh wind port 16 is provided with the upside of electrostatic filter 161, in the inside of housing 1 and and exhaust outlet
19 corresponding positions are provided with the second air-valve 191 for opening and closing exhaust outlet 19, on the first dividing plate 11 and in high efficiency filter
The downside of device 162 is provided with the 3rd air-valve 111.This structure setting can effectively strengthen the use flexibility of unit and environment adapts to energy
Power.In actual applications, by allowing the first air-valve 163 and the second air-valve 191 to open, and the 3rd air-valve 111 is allowed to close, you can as
The first implementation method makes unit operation.But only need to lower the temperature room air when Summer Indoor need not supplement fresh air
During dehumidifying, fresh wind port 16 and exhaust outlet 19 can be closed by the first air-valve 163 and the second air-valve 191, and allow the 3rd air-valve 111 dozens
Open, allow indoor return air to pass sequentially through return air inlet 18, the horizontal air channel of the second plate type heat exchanger 3, the transverse direction of the first plate type heat exchanger 2
Air channel, air-cooled condenser 7, the 3rd air-valve 111, the vertical air channel of the first plate type heat exchanger 2, evaporator 6, the second plate type heat exchanger
3 vertical air channel, reheater 8 and air outlet 17 send interior back to again, it is achieved thereby that to the circulation temperature lowering dehumidifying of room air
Reason.In the process of running, return air has carried out heat exchanging process twice in the first plate type heat exchanger 2 and the second plate type heat exchanger 3,
Make return air that there is relatively low temperature when reaching evaporator 6, the cold consumption of evaporator 6 can be reduced, improve cryogenic energy utilization
Rate and cool-down dehumidification effect, can equally make the return air of arrival reheater 8 has of a relatively high temperature, reduces reheater 8
Heat consumption, realizes reduction consumption reduction, improves the technical purpose of Energy Efficiency Ratio.
A kind of schematic diagram of the third implementation method of interior circulation heat recovery fresh air unit of the invention as shown in Figure 4, with preceding two
Plant unlike implementation method, the third specific embodiment is also on second partition 12 and in the downside of high efficiency particulate air filter 162
There is provided the 4th air-valve 121.This structure setting further enhances use flexibility and the adaptive capacity to environment of unit, makes unit
More different operational modes can be selected according to indoor and outdoor air situation, while unit applicability is strengthened, can lead to unit
Cross control device and realize intelligence and low energy consumption operation.In actual applications, by allowing the first air-valve 163 and the second air-valve 191 dozens
Open, and allow the 3rd air-valve 111 and the 4th air-valve 121 to close, you can as the first implementation method makes unit operation.Only needed when summer
When carrying out cool-down dehumidification to room air, can by allowing the first air-valve 163, the second air-valve 191 and the 4th air-valve 121 to close,
And allow the 3rd air-valve 111 to open, you can as second implementation method makes unit operation.But work as and only need to that interior is carried out to supplement new
When wind is processed without carrying out cool-down dehumidification, can be by allowing the first air-valve 163, the second air-valve 191 and the 4th air-valve 121 dozens
Open, and allow the 3rd air-valve 111 to close, fresh air can pass sequentially through fresh wind port 16, the 4th air-valve 121, reheater 8 and air outlet 17
Rapidly enter interior, and return and to pass sequentially through return air inlet 18, the horizontal air channel of the second plate type heat exchanger 3, the first plate type heat exchanger 2
Horizontal air channel, air-cooled condenser 7 and exhaust outlet 19 can discharge it is outdoor, now allow compressor 4, water-cooled condenser 5, evaporator 6,
Air-cooled condenser 7 and reheater 8 are stopped, it is only necessary to which breeze fan 171 and the operation of exhaust fan 181 can reach quick
The purpose of ventilation, and realize that low energy consumption runs.
It should be noted that the present invention is also provided with control device in actual applications, allow control device respectively with compression
Machine 4, breeze fan 171, exhaust fan 181, the first air-valve 163, the second air-valve 191, the 3rd air-valve 111 and the 4th air-valve 121
Electrical connection, and allow compressor 4 to use frequency-changeable compressor, to make unit to select different operations according to indoor and outdoor air situation
Pattern, reaches the purpose of Based Intelligent Control and low energy consumption operation.In addition, the present invention is also set in the downside of evaporator under normal circumstances
