Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present embodiment is described with reference to a method for controlling an air conditioner and a total-heat fresh air machine in an interlocking manner, the scope of the present invention is not limited thereto, and those skilled in the art can apply the present invention to other application scenarios without departing from the principle of the present invention.
In order to solve the above problems in the prior art, that is, to solve the problems that the existing air conditioner is used in a full-hot fresh air machine at the same time, not only the operation process of a user is various, but also energy waste is easily caused, the adjustment is not timely, and the use experience of the user is reduced, the embodiment provides a linkage control method of the air conditioner and the full-hot fresh air machine.
The full-hot fresh air fan is a fresh air and exhaust air interchanger containing a heat exchange core body. The total heat fresh air machine is a high-efficiency energy-saving heat recovery device, and can preheat or precool fresh air introduced into the room or air conditioner by recovering waste heat in exhaust, and can reduce (increase) fresh air enthalpy value before the fresh air enters the room or the surface cooler of the air conditioner to be subjected to heat-moisture treatment.
When the total heat fresh air fan works, indoor exhaust air and fresh air respectively flow through the heat exchanger core body in an orthogonal mode, because the temperature difference and the steam partial pressure difference exist in the air flow at the two sides of the airflow separation plate, the heat and mass transfer phenomena are generated when the two air flows pass through the separation plate, and the total heat exchange process is caused. When the air conditioner runs in summer, the fresh air obtains cold energy from the air exhaust of the air conditioner, so that the temperature is reduced, and meanwhile, the fresh air is dried by the air conditioner, so that the moisture content of the fresh air is reduced; when the air conditioner runs in winter, the fresh air is exhausted from the air conditioning room to obtain heat, and the temperature is increased. Therefore, the energy of the fresh air is recovered from the air exhaust of the air conditioner through the total heat exchange process of the heat exchange core body.
In the application, the working modes of the full-hot fresh air fan comprise a full-hot positive pressure mode, a full-hot standard mode, an internal circulation mode and a bypass mode. In the positive pressure mode, the total heat fresh air fan enables the indoor fresh air volume to be larger than the air volume, enables the indoor to be changed into a fresh oxygen-enriched space, enables people to feel more comfortable, and simultaneously transfers the cold or heat of the air discharged to the outdoor to the fresh air entering the indoor; in the full heat standard mode, the full heat fresh air fan enables the fresh air introducing amount and the fresh air discharging amount to be approximately equal, and meanwhile, the heat or the cold of the air discharged to the outside is transferred to the fresh air entering the room. Under the internal circulation mode, the full-hot fresh air fan filters the indoor air while circulating the indoor air to ensure the indoor air to be fresh. In the bypass mode, the full-hot fresh air fan only carries out normal exchange of indoor air and outdoor air, and the outdoor air does not need to pass through the full-heat exchange module when entering the room.
As shown in fig. 1, the method for controlling the air conditioner and the total-heat fresh air machine in an interlocking manner according to the present embodiment includes:

The controller can be a controller independent of the air conditioner and the full-heat fresh air machine, or an execution instruction of the linkage control method of the air conditioner and the full-heat fresh air machine provided by the embodiment can be stored in the controller of the air conditioner or the full-heat fresh air machine, and the air conditioner and the full-heat fresh air machine are in communication connection.
The actual temperature difference is a temperature difference value obtained by subtracting the indoor environment temperature from the outdoor environment temperature. When the outdoor environment temperature is higher than the indoor environment temperature, the actual temperature difference value is a positive value; when the outdoor ambient temperature is less than the indoor ambient temperature, the actual temperature difference is a negative value.
According to the linkage control method of the air conditioner and the total-heat fresh air fan, the actual temperature difference value of the outdoor environment temperature and the indoor environment temperature is obtained through calculation, and the total-heat fresh air fan is controlled based on the actual temperature difference value. The full-hot fresh air machine realizes automatic control, realizes linkage control of the air conditioner and the full-hot fresh air machine, avoids excessive manual operation processes, is favorable for saving energy, and is timely for regulating and controlling the full-hot fresh air machine, so that the use experience of a user is improved.
As a preferred embodiment of the method for controlling the air conditioner and the total-heat fresh air blower in an interlocking manner according to the present embodiment, in step S300, the step of controlling the total-heat fresh air blower based on the actual temperature difference includes: comparing the actual temperature difference value with a preset first temperature difference threshold value and a preset second temperature difference threshold value respectively; wherein the first temperature difference threshold is greater than the second temperature difference threshold; and controlling the total-heat fresh air machine based on the comparison result.
Illustratively, the first temperature differential threshold may be 2 to 5 ℃ and the second temperature differential threshold may be-2 to-5 ℃. For example, the first temperature difference threshold may be set to 3 ℃ and the second temperature difference threshold may be set to-3 ℃. A plurality of temperature ranges can be defined according to the first temperature difference threshold and the second temperature difference threshold, and when the actual temperature difference value between the outdoor environment temperature and the indoor environment temperature is in different temperature ranges, the full-hot fresh air fan is correspondingly controlled.

At the moment, the total heat fresh air machine only carries out normal exchange of indoor air and outdoor air, and the outdoor air does not need to pass through the total heat exchange module when entering the room. Therefore, on the basis of ensuring the indoor air to be fresh, the energy waste is also avoided.

Illustratively, in summer or winter, after the air conditioner refrigerates or heats the indoor air for a period of time, the difference between the indoor and outdoor ambient temperatures will gradually increase, when the actual temperature difference is greater than the first temperature difference threshold or less than the second temperature difference threshold, the working mode of the air conditioner needs to be obtained, the full-heat fresh air fan is controlled more accurately based on the comparison result and the working mode of the air conditioner, the cold or heat of the air exhausted to the outdoor by the full-heat fresh air fan is recovered in time, and the cold or heat is supplemented to the fresh air. On the basis of ensuring the freshness of indoor air, the waste of indoor cold or heat is reduced, and the problem of energy waste caused by increasing the power consumption of an air conditioner is avoided.

For example, in summer, after the air conditioner cools the indoor air for a period of time, when the actual temperature difference between the outdoor environment temperature and the indoor environment temperature is greater than the first temperature difference threshold value and the air conditioner is in the dehumidification mode, the wind speed of the indoor unit of the air conditioner is low, most of the cooling capacity generated by the indoor unit of the air conditioner is used for balancing the latent heat of the indoor air, and the water vapor is changed into condensed water for dehumidification. The total-heat fresh air fan is adjusted to be in a total-heat standard mode, so that the fresh air introducing amount and the fresh air discharging amount are approximately equal, meanwhile, the heat of the air discharged to the outside is transferred to the fresh air entering the room, and the dehumidification effect of the air conditioner is not influenced on the basis of ensuring the freshness of the indoor air.
