Optionally, a section of the fresh air duct located in the chamber is used as an indoor fresh air duct, and the external electric heater surrounds the outer wall of the indoor fresh air duct.
Optionally, the in-pipe electric heater is a mesh structure, and the in-pipe electric heater is mounted on the inner cross section of the indoor fresh air pipe.
Referring to fig. 2a and 2b, an embodiment of a control method of a fresh air conditioner is applied to an air conditioner 21, the air conditioner 21 includes a fresh air blower and a fresh air duct 22, an electric heater 24 in the fresh air duct 22 is arranged in the fresh air duct, and an electric heater 23 outside the fresh air duct is wound outside the fresh air duct.
It should be noted that the air-conditioning fresh air system is one of three air circulation systems of the air conditioner, namely, an indoor air circulation system, an outdoor air circulation system and a fresh air system. The fresh air system has the main functions of realizing the circulation and the ventilation between the room air and the outdoor air and purifying the air. The air conditioner 21 of the present embodiment includes a fresh air blower and a fresh air duct 22. When the fresh air function is started, the air conditioner discharges indoor waste gas by controlling the fresh air machine to work, so that indoor and outdoor pressure is generated, and under the action of the indoor and outdoor pressure, outdoor air flows into the room through the fresh air pipeline 22 to complete indoor ventilation. In order to prevent electric leakage and save cost, the fresh air pipe of this embodiment is an insulating plastic pipe.
It should be noted that the fresh air duct 22 extends from the indoor to the outdoor, and in practical applications, it is divided into an indoor fresh air duct and an outdoor fresh air duct according to a wall on which the air conditioner is installed. In this embodiment, one segment of the fresh air duct 22 located in the room is used as an indoor fresh air duct, and the external electric heater 23 surrounds the outer wall of the indoor fresh air duct. When the installer installs the air conditioner, a segment of the fresh air duct 22 around which the external electric heater 23 is wound can be installed indoors according to the position of the external electric heater 23.
The in-pipe electric heater 24 of the present embodiment is a mesh structure, and the in-pipe electric heater 24 is installed at the inner cross section of the indoor fresh air pipe. The outer ring of the electric heater 24 in the tube with the net structure is fixed on the inner wall of the indoor fresh air pipe. In one embodiment, the fresh air duct to which the in-duct electric heater 24 is mounted is disposed near the intersection of the indoor and outdoor spaces when the air conditioner is installed.
Referring to fig. 3, the fresh air conditioner control method includes:
step S302, detecting indoor temperature and outdoor temperature;
in this embodiment, when the air conditioner starts the new trend mode, begin to detect the indoor temperature in the room that the air conditioner is located to detect outdoor temperature. Specifically, the air conditioner detects an indoor temperature using an indoor temperature sensor provided in the indoor unit, and detects an outdoor temperature using an outdoor temperature sensor provided in the outdoor unit.
Step S304, comparing the indoor temperature and the outdoor temperature;
in this embodiment, the air conditioner compares the indoor temperature and the outdoor temperature to obtain the magnitude relationship between the indoor temperature and the outdoor temperature, so as to execute step S306 according to the magnitude relationship between the indoor temperature and the outdoor temperature.
And S306, if the indoor temperature is higher than the outdoor temperature, controlling the external electric heater to heat.
It should be understood that when the indoor temperature is higher than the outdoor temperature, that is, the temperature of the outdoor air is lower than the temperature of the indoor air, after the outdoor air with lower temperature enters the fresh air duct, the temperature of the tube wall of the fresh air duct directly contacting the outdoor air with lower temperature is reduced, and at this time, the indoor air with higher temperature may encounter the outer wall of the indoor fresh air duct with lower temperature to generate condensation. Therefore, in this embodiment, the air conditioner controls the external electric heater located on the outer wall of the indoor fresh air duct to heat the outer wall of the indoor fresh air duct located indoors in the fresh air duct, so as to prevent the indoor air from generating condensation on the outer wall of the indoor fresh air duct.
Step S308, if the indoor temperature is lower than the outdoor temperature, the electric heater in the pipe is controlled to heat.
It should be appreciated that when the indoor temperature is less than the outdoor temperature, i.e., the outdoor air temperature is higher than the indoor air temperature, the outdoor air will likely form condensation as soon as it enters the indoor portion of the fresh air duct at a very high rate. Therefore, in this embodiment, the electric heater 24 in the air conditioner control pipe heats the air to heat the inner wall of the indoor fresh air pipe and the indoor air in the indoor fresh air pipe, so as to prevent the outdoor air from generating condensation when encountering the indoor air with lower temperature.
In addition, in the fresh air mode, the indoor temperature and the outdoor temperature are detected in real time, that is, step S302 and step S304 are performed in real time, and if the magnitude relationship between the indoor temperature and the outdoor temperature changes, the operating states of the external electric heater and the internal electric heater are switched accordingly. For example, if the air conditioner detects that the indoor temperature is lower than the outdoor temperature in the state that the external electric heater is operated, the external electric heater is turned off to stop heating, and the internal electric heater is started to start heating. It is understood that at most one of the outside electric heater and the inside electric heater is in operation at the same time.
In addition, in the present embodiment, if the indoor temperature and the outdoor temperature are the same, the operating states of the external electric heater and the internal electric heater are maintained. For example, when the fresh air mode is just started, if the air conditioner detects that the indoor temperature and the outdoor temperature are consistent, the external electric heater and the internal electric heater are both kept in the stop state. After the fresh air mode is started, and one of the external electric heater and the internal electric heater is working, if the air conditioner detects that the indoor temperature is consistent with the outdoor temperature, the current working states of the external electric heater and the internal electric heater are kept.
In this embodiment, through detecting indoor temperature and outdoor temperature, compare indoor temperature and outdoor temperature's size, if indoor temperature is greater than outdoor temperature, then control surrounds the outer electric heater of outside of tubes outside the new trend pipeline and heats, with heating the outer wall of new trend pipeline, avoided the higher indoor air of temperature to meet the lower new trend pipeline outer wall of temperature and produce the condensation, if indoor temperature is less than outdoor temperature, then control sets up the intraductal electric heater in the new trend pipeline and heats, with heating the indoor air in the new trend pipeline, avoided the higher indoor air of temperature to meet the lower indoor temperature of temperature and produce the condensation in the new trend pipeline, thereby comprehensive emergence of having avoided the new trend condensation.
Referring to fig. 4, in one embodiment, the step S306 specifically includes:
step S402, calculating the absolute value of the difference between the indoor temperature and the outdoor temperature;
and S404, if the absolute value of the difference value is greater than or equal to the preset temperature, controlling the external electric heater to operate at a first heating power.
It should be noted that, in this embodiment, when the air conditioner determines that the indoor temperature is greater than the outdoor temperature, the absolute value of the difference between the indoor temperature and the outdoor temperature is further calculated, and the absolute value of the difference is compared with the preset temperature. Wherein the preset temperature is the critical temperature of the condensation. It can be understood that when the absolute value of the difference between the indoor temperature and the outdoor temperature is greater than the preset temperature, the probability of occurrence of condensation is high, and when the absolute value of the difference between the indoor temperature and the outdoor temperature is less than the preset temperature, the probability of occurrence of condensation is low. The preferred value range of the preset temperature provided by this embodiment is 5-25 ℃, and a person skilled in the art can select a suitable temperature value within the preferred value range as the preset temperature according to the actual environment.
It should be noted that, if the absolute value of the difference is greater than or equal to the preset temperature, it indicates that the probability of condensation occurring in the current indoor and outdoor temperature difference is high, and therefore the air conditioner controls the electric heater outside the tube to operate at the first heating power so as to heat the outer wall of the indoor fresh air tube. Wherein the first heating power is higher. In this embodiment, the first heating power is preferably in a range of 50W to 200W. Those skilled in the art can select an appropriate power value within the preferred range as the first heating power according to the actual environment.
This embodiment is through the big or small relation of the difference absolute value of judging indoor temperature and outdoor temperature and predetermineeing the temperature, when difference absolute value more than or equal to predetermineeing the temperature, in the face of the great abominable operating mode that very easily takes place the condensation of indoor outer difference in temperature promptly, control extra-tubular electric heater with the operation of first heating power to can the adaptability with the outer wall temperature of indoor fresh air pipe and the difference in temperature maintenance of indoor temperature in a less within range, more effectual emergence that has prevented fresh air pipeline outer wall condensation.
In one embodiment, the step S406 further includes: and controlling the fresh air fan to run at a first rotating speed.
It should be noted that, in this embodiment, the air conditioner controls the electric heater outside the tube to heat at the first heating power, and also controls the fresh air blower to operate at the first rotation speed. Wherein, first rotational speed can be a relatively less speed to under the great extremely abominable operating mode that takes place the condensation of indoor outer difference in temperature, slow down the indoor speed of outdoor air inflow, thereby slowed down the reducing speed of indoor fresh air pipe temperature, thereby better avoid the emergence of fresh air pipeline outer wall condensation. The preferred range of the first rotation speed provided by the present embodiment is 1000rmp to 1800 rmp. The person skilled in the art can select a suitable value of the rotation speed within the preferred range as the first rotation speed according to the actual circumstances.

step S502, if the absolute value of the difference value is smaller than the preset temperature, the external electric heater is controlled to operate at a second heating power. Wherein the first heating power is greater than the second heating power.
It should be noted that, if the absolute value of the difference is smaller than the preset temperature, it indicates that the probability of condensation occurring in the current indoor and outdoor temperature difference is low, and at this time, the air conditioner controls the electric heater outside the tube to operate at the second heating power, so as to heat the outer wall of the indoor fresh air tube. Wherein the second heating power is smaller than the first heating power. Because the probability of condensation is lower, therefore can select lower heating power as second heating power, save the electric quantity when can effectively prevent fresh air pipeline outer wall condensation. In this embodiment, the second heating power is preferably in the range of 10W to 50W. Those skilled in the art can select an appropriate power value within the preferred range as the second heating power according to the actual environment.
This embodiment is through the big or small relation of difference absolute value and the predetermined temperature of judging indoor temperature and outdoor temperature, when the difference absolute value is less than predetermined temperature, when the less difficult operating mode condition who takes place the condensation of indoor outer difference in temperature promptly, the operation of the second heating power that the control tube outer electric heater was lower with heating power to can the adaptability effectively prevent fresh air pipeline outer wall condensation under lower heating power, saved the electric quantity.
In one embodiment, the step S502 further includes: and controlling the fresh air machine to operate at a second rotating speed. Wherein the first rotational speed is less than the second rotational speed.

The second rotating speed is greater than the first rotating speed and is a smaller speed relative to the first rotating speed. The air conditioner accelerates the indoor speed of outdoor air inflow under the working condition that the indoor and outdoor temperature difference is small and condensation is not easy to occur, thereby accelerating the speed of fresh air change, effectively preventing condensation of the outer wall of the fresh air pipeline, ensuring the air change speed of the fresh air and improving the user experience. The second rotation speed provided by the embodiment is preferably 1800 rmp-3000 rmp. The person skilled in the art can select a suitable value of the rotation speed as the second rotation speed within the preferred range according to the actual circumstances.

It should be noted that, in this embodiment, when the air conditioner determines that the indoor temperature is lower than the outdoor temperature, the air conditioner further calculates a second absolute difference value between the indoor temperature and the outdoor temperature, and compares the second absolute difference value with the preset temperature. Wherein the preset temperature is the critical temperature of the condensation.
It should be noted that, if the absolute value of the second difference is greater than or equal to the preset temperature, it indicates that the probability of condensation occurring in the current indoor and outdoor temperature difference is high, and therefore the air conditioner controls the electric heater in the tube to operate at the first heating power so as to heat the indoor air in the indoor fresh air tube. Wherein the first heating power is higher. In this embodiment, the first heating power is preferably in a range of 50W to 200W. Those skilled in the art can select an appropriate power value within the preferred range as the first heating power according to the actual environment.
This embodiment is through the big or small relation of the second difference absolute value and the predetermined temperature of judging indoor temperature and outdoor temperature, when the second difference absolute value more than or equal to predetermined temperature, in the face of the great extremely easy bad operating mode that takes place the condensation of indoor outer difference in temperature promptly, the operation of electric heater in the control tube is with first heating power, thereby can be adaptability with the indoor air temperature in the indoor new trend pipe and the difference in temperature maintenance that gets into the outdoor temperature of indoor new trend pipe in a less within range, more effectual emergence that has prevented new trend pipeline inner wall condensation.
