An internal circulation mode: as shown in fig. 3, the fresh air machine stops conveying fresh air, only the air quality and the temperature and humidity of the indoor air are processed, and the service life of the fresh air purification component is prolonged. In this mode, the electric air valve 62 for fresh air is closed, the exhaust fan 52 is not operated, and the first and second air supply fans 42 and 44 are started. Indoor air can be sent to the indoor through the first air return opening 71, the first air return duct, the first negative ion purification assembly 1001, the first air return filter screen assembly 82, the heat exchanger 2, the air supply fan and the first air supply opening 41, and indoor air can be sent to the indoor through the second air return opening 72, the second air return duct, the second negative ion purification assembly 1002, the second air return filter screen assembly 83, the heat exchanger 2, the air supply fan and the second air supply opening 43. Because the air exhaust outlet is provided with the check valve, outdoor air cannot enter the room through the air exhaust outlet.
When the cooling and heating or dehumidifying mode is operated simultaneously in the mode, outdoor fresh air is not introduced, and only the temperature and humidity of indoor air are adjusted, so that the adjusting effect on the indoor air can be more quickly displayed.
Fresh air external circulation mode: as shown in fig. 4, the fresh air blower is used for introducing fresh air from the outside into the room while processing the return air from the room, so as to bring fresh air into the room. In this mode, the electric air valve 62 for fresh air is opened, the exhaust fan 52 is not operated, and the first and second air supply fans 42 and 44 are started. After the outdoor fresh air passes through the fresh air inlet, the fresh air duct, the fresh air valve, the fresh air filter screen component 81 and the heat exchanger 2 and the indoor air passing through the first air return opening 71, the first air return duct, the first negative ion purification component 1001 and the first air return filter screen component 82 are mixed, the mixed air is sent to the indoor space through the heat exchanger 2, the first air supply fan 42 and the first air supply opening 41 again. Outdoor fresh air passes through the fresh air inlet, the fresh air valve, the fresh air filter screen component 81 and the heat exchanger 2, can also be mixed with indoor air passing through the second air return inlet 72, the second air return duct, the second negative ion purification component 1002 and the second air return filter screen component 83, and then is sent to the indoor space through the heat exchanger 2, the second air supply fan 44 and the second air supply outlet 43 again. Because the air exhaust outlet is provided with the check valve, outdoor air cannot enter the room through the air exhaust outlet. When the mode of refrigeration and heating or dehumidification is operated simultaneously, outdoor fresh air passes through the heat exchanger 2 twice, and the temperature and humidity control of air is more obvious.
Air exhaust internal circulation mode: as shown in fig. 5, the fresh air blower discharges part of the indoor return air to the outside of the room in the process of internally circulating the indoor return air, and in this mode, the fresh air blower is a negative pressure type fresh air blower, the indoor pressure is lower than the outdoor pressure, and the outdoor air flows into the room through the window gap, so that the function of exchanging the indoor air and the outdoor air is realized. In this mode, the electric air valve 62 for fresh air is closed, the exhaust fan 52 is started, and the first and second air supply fans 42 and 44 are started. The indoor air is divided into two parts by the difference of the operation directions of the first supply fan 42 and the exhaust fan 52 after passing through the first return air opening 71. A small part of air enters the air exhaust duct through a first air exhaust inlet 1303 on the first air exhaust partition plate 1301 and is exhausted outdoors through an air exhaust fan 52; most of the remaining air is sent to the room through the first negative ion purification assembly 1001, the first air return screen assembly 82, the heat exchanger 2, the first air supply fan 42, and the first air supply outlet 41. Meanwhile, the indoor air is divided into two parts by the difference of the acting directions of the second supply fan 44 and the exhaust fan 52 after passing through the second return air inlet 72. A small part of air enters the air exhaust duct through a second air exhaust air inlet 1304 on the second air exhaust partition 1302 and is exhausted outdoors through the air exhaust fan 52; most of the remaining air is sent to the room through the second negative ion purification assembly 1002, the second return air filter screen assembly 83, the heat exchanger 2, the second air supply fan and the second air supply outlet 43.
Mixed circulation mode: as shown in fig. 6, the ventilation efficiency is the highest by introducing fresh air and discharging dirty air from a part of the room while treating the original air in the part of the room. In this mode, the electric air valve 62 for fresh air is opened, the exhaust fan 52 is started, and the first and second air supply fans 42 and 44 are started. The indoor air is divided into two parts by the difference of the operation directions of the first supply fan 42 and the exhaust fan 52 after passing through the first return air opening 71. A small part of air enters the air exhaust duct through a first air exhaust inlet 1303 on the first air exhaust partition plate 1301 and is exhausted outdoors through an air exhaust fan 52; most of the air left is mixed with the fresh air passing through the fresh air inlet, the fresh air duct, the fresh air valve, the fresh air filter screen assembly 81 and the heat exchanger 2 after passing through the first negative ion purification assembly 1001 and the first air return filter screen assembly 82, and then is sent to the indoor through the heat exchanger 2, the first air supply fan 42 and the first air supply outlet 41.
Meanwhile, the indoor air is divided into two parts by the difference of the acting directions of the second supply fan 44 and the exhaust fan 52 after passing through the second return air inlet 72. A small part of air enters the air exhaust duct through a second air exhaust air inlet 1304 on the second air exhaust partition 1302 and is exhausted outdoors through the air exhaust fan 52; most residual air is mixed with fresh air passing through a fresh air inlet, a fresh air duct, a fresh air valve, a fresh air filter screen component 81 and the heat exchanger 2 after passing through the first negative ion purification component 1001 and the second return air filter screen component 83, and then is sent to the indoor through the heat exchanger 2, the second air supply fan 44 and the second air supply outlet 43.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
