The invention discloses an anti-frosting and air-mixing energy-saving method of a fresh air main machine. The method comprises the following steps that the current temperature of the outdoor air is detected through a temperature and humidity sensor; an external circulation mode is started specifically when the outdoor temperature is the proper temperature, the external circulation mode is started,in the case of the air valve state, an air valve at a second fresh air port is opened, an air valve is closed at a second air return port is closed, and a fresh air fan and an exhaust fan are started; an air mixing mode is started, when the outdoor temperature is the relatively low temperature, the air mixing mode is started, in the case of the air valve state, the air valve at the second fresh air port is opened, the air valve at the second air return port is opened, and the fresh air fan and the exhaust fan are started; and an internal circulation mode is started, when the outdoor temperature is the quite low temperature or the quite high temperature, the internal circulation mode is started, in the case of the air valve state, the air valve at the second fresh air port is closed, the air valve at the second air return port is opened, the fresh air fan is started, and the exhaust fan is closed. According to the anti-frosting and air-mixing energy-saving method of the fresh air mainmachine, the working mode is changed in real time, so that the fresh air main machine is prevented from frosting, and the indoor air temperature is ensured to be comfortable.
Description
technical field [0001] The invention belongs to the field of a fresh air supply method for a fresh air host, and more specifically relates to a frost-proof and mixed air energy-saving method for a fresh air host. Background technique [0002] The fresh air main engine currently on the market includes a chassis shell, a full heat exchange core, a control device, a fresh air fan, an exhaust fan, a fresh air outlet, an exhaust outlet, a return air outlet, and an air supply outlet. For example, the application number 2018203884671 discloses a full Heat exchange device, the total heat exchange core is arranged in the chassis shell, the total heat exchange core divides the chassis shell into four areas, and the four exchange sides of the total heat exchange core are respectively connected to one area; the fresh air outlet and the exhaust air The air outlet is set on one side of the chassis shell, and the air return port and the air supply port are set on the other side of the chas...
