Embodiment Construction
[0068] The invention discloses a control method of a frequency conversion air conditioner, which can adjust the humidity of indoor air and reduce the system energy consumption of the frequency conversion air conditioner.
[0069] The control method of the frequency converter disclosed in the present invention comprises:
[0070] When the first preset condition is met, it is judged whether the current indoor environment needs dehumidification treatment;
[0071] When it is determined that dehumidification treatment is not required, perform a separate cooling operation within the first period of time, and then return to the step of judging whether the current indoor environment requires dehumidification treatment, and perform a separate cooling operation, including:
[0072] Obtain the tube temperature of the evaporator and the dew point temperature of the indoor air;
[0073] When the tube temperature is not higher than the dew point temperature, if the current operating frequ...

The invention discloses a control method for an inverter air conditioner. When it is determined that no dehumidification operation is required, if the tube temperature of the evaporator is higher than the dew point temperature of the indoor air, the compressor is controlled to maintain the current frequency; If the dew point temperature of the indoor air is higher than the dew point temperature of the indoor air, the frequency of the compressor will be reduced on the premise that the frequency reduction of the compressor is allowed, thereby increasing the tube temperature of the evaporator and reducing the dehumidification capacity of the inverter air conditioner; The tube temperature of the evaporator and the dew point temperature of the indoor air are used to control the operating frequency of the compressor, so that the inverter air conditioner can perform dehumidification while cooling and cooling. The control method of the frequency conversion air conditioner disclosed by the invention can adjust the humidity of the indoor air, and when the dehumidification operation is not required, the dehumidification capacity of the air conditioner is reduced by reducing the operating frequency of the compressor, thereby reducing the energy consumption of the system. The invention also discloses a control device of the frequency conversion air conditioner and the frequency conversion air conditioner.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment control, and in particular relates to a control method, a control device and a frequency conversion air conditioner. Background technique [0002] Now more and more inverter air conditioners appear in people's lives. The existing air conditioning control method is based on the set temperature of the air conditioner for cooling control. When the difference between the indoor ambient temperature and the set temperature is large, the frequency of the compressor of the inverter air conditioner is increased. When the indoor environment When the difference between the temperature and the set temperature is small, the frequency of the compressor of the inverter air conditioner is reduced. [0003] However, according to the existing control method, the temperature of the evaporator tube of the inverter air conditioner may be too low. When the tube temperature of the evaporator is lower than...
