It is understood that Δ T in the heating mode and Δ T in the cooling mode may be the same or different.
In the refrigeration mode, in the process of controlling the fresh air system and the heat pump system to simultaneously operate, if the set temperature is lower than the outdoor temperature, whether the indoor temperature reaches the outdoor temperature is judged at this moment, when the outdoor temperature is reached, the fresh air system is controlled to stop, so that the heat pump system continues to refrigerate, and the heat pump system is controlled to operate/stop refrigerating subsequently according to whether the indoor temperature reaches the set temperature. And in the refrigeration mode, the fresh air system and the heat pump system are controlled to operate simultaneously, if the set temperature is not less than the outdoor temperature, whether the indoor temperature reaches the set temperature is judged in real time, when the indoor temperature reaches the set temperature, the fresh air system and the heat pump system are controlled to stop working, and subsequently, the fresh air system is controlled to operate/stop according to whether the indoor temperature reaches the set temperature. In the heating mode, in the process of controlling the fresh air system and the heat pump system to operate simultaneously, if the set temperature is not less than the outdoor temperature, whether the indoor temperature reaches the outdoor temperature is judged at this moment, when the outdoor temperature is reached, the fresh air system is controlled to stop, so that the heat pump system continues heating, and the heat pump system is controlled to operate/stop heating subsequently according to whether the indoor temperature reaches the set temperature. And in the heating mode, the fresh air system and the heat pump system are controlled to operate simultaneously, if the set temperature is lower than the outdoor temperature, whether the indoor temperature reaches the set temperature is judged in real time, the fresh air system and the heat pump system are controlled to stop working when the indoor temperature reaches the set temperature, and the fresh air system is controlled to operate/stop according to whether the indoor temperature reaches the set temperature. Through a more precise control method, energy can be more effectively saved, and the aim of quickly adjusting the indoor temperature is fulfilled.
It can be understood by those skilled in the art that, in a feasible real-time manner, during the process of controlling the heat pump system and the fresh air system to operate simultaneously, the magnitudes of the indoor temperature and the set temperature can be directly determined in real time without determining the magnitudes of the set temperature and the outdoor temperature, and when the indoor temperature reaches the set target temperature, the fresh air system and the heat pump system are controlled to stop operating. And when the difference value between the indoor temperature and the target temperature exceeds a set value, the heat pump system and the fresh air system are started to adjust the indoor temperature. However, such a control method is obviously not as effective as the energy saving effect of the above embodiment.
In another possible embodiment, if T is T when the determined operation mode is the cooling modeInner part＞TOuter coverAnd at the moment, the fresh air system is controlled to operate, and the indoor temperature T is judged in real timeInner partAnd outdoor temperature TOuter coverWhen the indoor temperature T is large or smallInner partTo the outdoor temperature TOuter coverAnd when the air flow is the same, the fresh air system is controlled to be closed. In-line with the aboveThen according to the indoor temperature TInner partAnd a set temperature TIs provided withTo control the heat pump system on or off. If T is the heating mode when the determined working mode is the heating modeInner part＜TOuter coverAt the moment, the fresh air system is controlled to operate, and the indoor temperature T is judgedInner partAnd outdoor temperature TOuter coverWhen the indoor temperature T is large or smallInner partTo the outdoor temperature TOuter coverAnd when the air flow is the same, the fresh air system is controlled to be closed. Then, according to the indoor temperature TInner partAnd a set temperature TIs provided withTo control the heat pump system on or off.
In practical use, when the air conditioner is started for the first time, a user needs to select a refrigeration mode or a heating mode through a remote controller, and when the air conditioner is started for the subsequent time, the default working mode of the air conditioner is the working mode of the air conditioner in the last working process, so that the operation of setting the working mode by the user is reduced, and certain convenience is provided for the user. However, for elderly people of some ages, they are not familiar with the operation of air conditioners. Generally, young people teach them how to set the mode of operation and adjust the temperature at the time of initial use. During long-term use, temperature adjustment is often used and not forgotten, and the setting of the working mode is rarely used and is easily forgotten. When the working mode needs to be changed, part of the old people can be overwhelmed and cannot use the fresh air conditioner. In addition, when the air conditioner is provided with an operation mode selection button, the user may set the operation mode by mistake. For example, in summer, the working mode can be adjusted to the heating mode when the infant plays with the remote controller, and for example, in summer, the user presses the wrong button on the remote controller occasionally to adjust the working mode to the heating mode when adjusting the temperature, so that the condition that the indoor space is rather hotter after the air conditioner works for a period of time can occur. These conditions are often ignored as they occur infrequently.
In view of this, the control method of the fresh air conditioner of the present invention is further improved. Preferably, the working mode of the fresh air conditioner is determined by the following method:
if the set temperature is higher than the indoor temperature, determining that the working mode of the indoor fresh air conditioner is a heating mode;
and if the set temperature is lower than the indoor temperature, determining that the working mode of the fresh air conditioner is the refrigeration mode.
By the method, the user does not need to select the working mode when starting the computer, and the controller can automatically determine the working mode according to the monitored indoor temperature and outdoor temperature, so that the situation that the user mistakenly sets the working mode to seriously influence the use experience is avoided.
In addition, the invention also provides a fresh air conditioner, which comprises a storage; a computer program stored in the memory and configured to be executed by the processor to implement the control method of the fresh air conditioner of any of the above embodiments. It will be appreciated by those skilled in the art that the fresh air conditioner may be a wall mounted air conditioner, a ceiling mounted air conditioner, a cabinet air conditioner, or the like.
In addition, the invention also provides a computer readable storage medium, which stores a computer program, and the computer program is executed by a processor to realize the control method of the fresh air conditioner in any embodiment.
As can be seen from the above description, in the preferred technical solution of the present invention, the fresh air conditioner includes a heat pump system and a fresh air system, and the control method of the fresh air conditioner includes the following steps: determining the working mode of the fresh air conditioner; acquiring indoor temperature and outdoor temperature; comparing the indoor temperature with the outdoor temperature; and selectively controlling the fresh air system and the heat pump system to operate simultaneously or the heat pump system to operate independently according to the current working mode and the comparison result. Specifically, when the fresh air conditioner is started, the set temperature, the indoor temperature and the outdoor temperature are obtained, the set temperature and the indoor temperature are compared, if the set temperature is higher than the indoor temperature, the working mode of the fresh air conditioner is determined to be the heating mode, and if the set temperature is lower than the indoor temperature, the working mode of the fresh air conditioner is determined to be the cooling mode. Meanwhile, the indoor temperature and the outdoor temperature are compared.
