Control method and device for air conditioner as well as air conditioner

Abstract

The invention discloses a control method and device for an air conditioner as well as the air conditioner. The control method for the air conditioner comprises the steps as follows: air conditioner operation environment parameters are acquired; the air conditioner target temperature and the inner air blower rotating speed are determined according to the air conditioner operation environment parameters; and the frequency of a compressor is adjusted on the basis of the air conditioner operation environment parameters, the target temperature and the inner air blower rotating speed. The air conditioner operation environment parameters include multiple parameters, many parameters affecting air conditioner temperature control can be considered, the air conditioner temperature control precision can be improved, closed-loop control can be performed over the frequency of the compressor of the air conditioner according to the air conditioner operation environment parameters as well as the targettemperature and the inner air blower rotating speed which are determined according to the environment parameters, the temperature conditioned by the air conditioner can be controlled relatively precisely, and the relatively-high comfort of the air conditioner and the relatively-good user experience can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner control method, device and air conditioner. Background technique [0002] In people's lives, air conditioners are already indispensable household appliances. The cooling or heating comfort of air conditioners is very important to the human body, especially the temperature drop or rise rate and the air outlet temperature, which can bring practical benefits to users and improve user comfort. comfort. [0003] In order to better satisfy the user's comfort, in the prior art, when the user uses the air conditioner, the temperature is generally adjusted manually according to experience. Since the indoor and outdoor ambient temperature fluctuates greatly, different indoor and outdoor ambient temperatures require different air-conditioning temperatures. Through manual adjustment, the indoor temperature control accuracy is inaccurate and the user's comfort...

Problems solved by technology

[0003] In order to better satisfy the user's comfort, in the prior art, when the user uses the air conditioner, the temperature is generally adjusted manually according to experience. Since the indoor and outdoor ambient temperature fluctuates greatly, different indoor and outdoor ambient temperatures require different air-conditioning temperatures. Through manual adjustment, the indoor temperature control accuracy is inaccurate and the user's comfort experience is poor

In the patent CN106196485A, the corresponding cooling and heating value under the current set temperature is obtained (the cooling and heating value is determined by the radiation temperature in the room and the temperature value of the human body surface), and the setting temperature of the air conditioner is adjusted according to the cooling and heating value. However, to obtain the temperature and temperature value, it is necessary to install an additional temperature and temperature detection device, which increases the cost of the air conditioner

In the patent CN105371434B, the set temperature of the air conditioner is obtained according to the outdoor temperature and the set temperature, but because it only considers the outdoor temperature and ignores the influence of indoor environmental parameters (for example, indoor humidity, indoor temperature) or the temperature difference between the indoor temperature and the target temperature, it will lead to The accuracy of indoor temperature control is inaccurate and the heating and cooling rate cannot meet the needs of users, resulting in poor comfort experience of users using air conditioners
