and S301, acquiring the internal environment temperature and the external environment temperature of the space in the running process of the air conditioner external unit.
S302, controlling the operation of the air exhaust equipment according to the temperature difference between the internal environment temperature and the external environment temperature.
The internal environment temperature of the space can be detected by the temperature sensor inside the space, and the external environment temperature of the space refers to the external environment temperature, namely the environment temperature of outdoor atmosphere, and can be detected by the temperature sensor outside the space. The energy gathering degree of the space where the air conditioner outdoor unit is located can be embodied by the temperature difference between the internal environment temperature and the external environment temperature, the operation of the air exhaust device is controlled according to the temperature difference, the space where the air conditioner outdoor unit is located and the external forced ventilation heat exchange are achieved, the energy gathering of the space where the air conditioner outdoor unit is located is avoided, the air conditioner outdoor unit is guaranteed to operate in the best energy-saving state, and the capacity and the energy efficiency of the air conditioner are prevented from being reduced.
According to the air exhaust control method, the air exhaust device is installed in the space where the air conditioner external unit is located, the internal environment temperature and the external environment temperature of the space are obtained in the operation process of the air conditioner external unit, the operation of the air exhaust device is controlled according to the temperature difference between the internal environment temperature and the external environment temperature, therefore, the purpose of forced ventilation and heat exchange between the space where the air conditioner external unit is located and the outside is achieved by utilizing the air exhaust device, the energy accumulation of the space where the air conditioner external unit is located is avoided, the air exhaust volume is adjusted according to the actual temperature difference, the air conditioner is kept to operate in the optimal energy-saving state, the capacity and the energy efficiency of the air.
Before controlling the operation of the exhaust device according to the temperature difference between the internal environment temperature and the external environment temperature, the method further comprises the following steps: calculating the temperature difference between the internal ambient temperature and the external ambient temperature, specifically calculating by any one of the following methods:
(1) calculating according to an operation mode of an air conditioner external unit (namely, an operation mode of air conditioning equipment), specifically, if the operation mode of the air conditioner external unit is a refrigeration mode, calculating the difference between the internal environment temperature and the external environment temperature; and if the operation mode of the air conditioner external unit is a heating mode, calculating the external environment temperature minus the internal environment temperature to obtain the temperature difference. As described above, in the cooling mode, the space where the air conditioner external unit is located collects heat, which causes the temperature in the space to rise, i.e., the internal ambient temperature is higher than the external ambient temperature, and therefore, in the cooling mode, the internal ambient temperature minus the external ambient temperature is calculated to obtain the temperature difference; in the heating mode, cold energy is collected in the space where the air conditioner outdoor unit is located, so that the temperature in the space is reduced, namely the internal environment temperature is lower than the external environment temperature, and therefore, in the heating mode, the external environment temperature is calculated to subtract the internal environment temperature, and the temperature difference is obtained.
The method calculates the temperature difference by combining with the operation mode of the air conditioner external unit, can ensure that the calculated temperature difference is positive, and is favorable for controlling the air exhaust amount according to the temperature difference.
(2) Calculating an absolute value of a difference between the internal ambient temperature and the external ambient temperature as the temperature difference.
The absolute value of the difference value between the internal environment temperature and the external environment temperature is calculated by the method and is used as the temperature difference, the operation mode of an air conditioner external unit does not need to be considered, the calculated temperature difference is positive, the control of the air exhaust amount according to the temperature difference is facilitated, and the calculation method is simple and easy to realize.
In one embodiment, if only one air exhaust device is installed in a space where an external unit of an air conditioner is located, controlling the operation of the air exhaust device according to a temperature difference between the internal ambient temperature and the external ambient temperature includes: if the temperature difference between the internal environment temperature and the external environment temperature is smaller than a first preset threshold value, controlling the exhaust equipment to be in a closed state; and if the temperature difference between the internal environment temperature and the external environment temperature is greater than or equal to the first preset threshold value, controlling the air exhaust equipment to be in an opening state, and controlling the air exhaust amount generated by the air exhaust equipment according to a first preset rule.
The first preset threshold is a temperature difference threshold used for controlling the air exhaust device, and can be set according to a capacity-temperature curve graph and an energy efficiency-temperature curve graph of the air conditioning device, wherein the temperatures in the capacity-temperature curve graph and the energy efficiency-temperature curve graph refer to the internal environment temperature of a space where an air conditioner external unit is located, the two curve graphs can reflect the influence of the internal environment temperature of the space where the air conditioner external unit is located on the capacity and the energy efficiency of the air conditioning device, and the first preset threshold can be reasonably set by combining the two curve graphs and the external environment temperature at the time to serve as a basis for controlling the air exhaust device. The temperature difference between the internal environment temperature and the external environment temperature is smaller than a first preset threshold value, the air exhaust equipment is controlled to be in a closed state, the temperature difference between the inside and the outside of the space can be controlled within an acceptable range, namely, the range with little influence on the capacity and the energy efficiency of the air conditioning equipment is controlled, and the air exhaust equipment can be prevented from being started and stopped frequently. For example, the first preset threshold value is 1 ℃. It should be noted that the same air conditioning equipment may use the same temperature difference threshold value in different operation modes (cooling or heating, etc.), or may use different temperature difference threshold values.
The specific meaning of "controlling the exhaust equipment to be in a closed state" is: if the air exhaust equipment is in the opening state at present, the air exhaust equipment is closed; if the air exhausting equipment is in the closing state at present, the air exhausting equipment is kept closed continuously. Correspondingly, "controlling the exhaust device to be in an open state" specifically means: if the air exhaust equipment is in a closed state at present, the air exhaust equipment is opened; if the air exhaust equipment is in the opening state at present, the air exhaust equipment is kept to be opened continuously.
The first preset rule is a rule for controlling the air discharge amount of a single air discharge device according to the range where the actual temperature difference is located, and may specifically include a corresponding relationship between the temperature difference range and the air discharge amount requirement. Different air discharge requirements can be realized by adjusting the fan gear (wind gear for short) or the operating frequency of the air discharging device. The air discharge amount generated by the air discharging device is the air discharge amount generated by the air discharging device in a unit time under the current operation state (gear or operation frequency) or the total air discharge amount generated by the air discharging device operating for a preset time length under the current operation state.
The embodiment aims at the condition that an air exhaust device is installed in the space where the air conditioner outdoor unit is located, the air exhaust device is controlled according to the temperature difference between the inside and the outside of the space where the air conditioner outdoor unit is located, the air exhaust device is timely closed or the air exhaust amount of the air exhaust device is adjusted according to the temperature difference, the air exhaust amount is adjusted according to actual requirements, the space where the air conditioner outdoor unit is located and the outside forced ventilation and heat exchange are accurately and reliably controlled, energy accumulation in the space where the air conditioner outdoor unit is located is avoided, the air conditioner is kept running in the best energy-saving state, the capacity and the energy efficiency of the.
Further, controlling the air discharge amount generated by the air discharge equipment according to a first preset rule, comprises: determining a first interval in which a temperature difference between the internal ambient temperature and the external ambient temperature is within a range greater than or equal to the first preset threshold; determining a first exhaust volume requirement corresponding to the first interval; and controlling the operation of the air exhaust equipment according to the first air exhaust quantity requirement.

The subdivision of the interval can be divided according to the exhaust air volume gear which can be adjusted by the exhaust equipment, that is, according to the fan gear or the operation frequency which the exhaust equipment has, for example, the exhaust equipment can adjust the exhaust air volume of three gears, and then the interval can be divided in the range which is larger than or equal to the first preset threshold value, and the three intervals respectively correspond to the exhaust air volume of three gears. The interval subdivision can be realized by setting a threshold value larger than the first preset threshold value, and similarly, the threshold value can also be set according to a capacity-temperature curve graph and an energy efficiency-temperature curve graph of the air conditioning equipment.
Illustratively, the first preset threshold value is 1 ℃, the first preset threshold value is subdivided into three intervals [1, 3], (3, 5] and (5, + ∞) through the thresholds of 3 ℃ and 5 ℃ in the interval [1, + ∞ ], the air exhaust volume requirement corresponding to the interval [1, 3] is smaller than the air exhaust volume requirement corresponding to the interval (3, 5], the air exhaust volume requirement corresponding to the interval (3, 5] is smaller than the air exhaust volume requirement corresponding to the interval (5, + ∞), therefore, the air exhaust volume adaptive to the actual temperature difference can be provided, and reasonable ventilation and heat exchange are realized.
This embodiment can be more accurate reliable control exhaust equipment's volume of airing exhaust through thinning the difference in temperature interval to reach reasonable effect of airing exhaust, avoid the outer machine of air conditioner place space energy gathering, keep air conditioning equipment at best energy-conserving state operation, avoid air conditioning equipment's ability and efficiency to descend, realize the energy-conserving effect of building totality wisdom.
