Frequency-variable air conditioner control method and control device, and frequency-variable air conditioner

Abstract

The invention discloses a frequency-variable air conditioner control method and control device, and a frequency-variable air conditioner. The control method includes: detecting the real time indoor environment temperature when a received air conditioner control command is a refrigeration energy conservation comfort command, and comparing the real time indoor environment temperature and the set indoor environment temperature threshold; controlling the frequency-variable air conditioner to run according to the original frequency-variable control mode of the frequency-variable air conditioner if the real time indoor environment temperature is not less than the set indoor environment temperature threshold; acquiring a compressor target frequency calculated based on the original frequency-variable control mode if the real time indoor environment temperature is less than the set indoor environment temperature threshold, and determining if the compressor target frequency is less than a first set compressor frequency or not; controlling a compressor to run at the first set compressor frequency if so, and controlling an outdoor fan to run at a set revolution speed; and controlling the compressor and the outdoor fan to run according to the original frequency-variable control mode if not. The control method can improve the energy-saving performance and the refrigeration comfort of the frequency-variable air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to an inverter air conditioner, and more specifically relates to a control method, a control device and an inverter air conditioner. Background technique [0002] In the hot summer, the indoor air can be cooled by using the inverter air conditioner to create a cool environment for users. However, inverter air conditioners consume a lot of power and often become the main power-consuming appliances in the home. [0003] In order to reduce the power consumption of the inverter air conditioner, there is a control method for the inverter air conditioner in the prior art. By detecting the outdoor ambient temperature, a preset compressor operating frequency corresponding to the outdoor ambient temperature is selected from several preset operating frequencies of the compressors. Control the inverter air conditioner with the preset compressor operating frequency. The lower...

Problems solved by technology

[0004] The above-mentioned control method takes the outdoor ambient temperature as the control parameter, and does not consider the influence of the indoor ambient temperature where the user is located, so it cannot be adjusted quickly and accurately according to the indoor ambient temperature. Comfort requirements for indoor ambient temperature

Moreover, the preset compressor operating frequency is directly proportional to the outdoor ambient temperature. If the outdoor ambient temperature is lower than a certain value, the preset compressor operating frequency will be very low

When the operating frequency of the compressor is as low as a certain value, it cannot achieve any cooling effect. At this time, although the power consumption is low, it is a pure power consumption and does not have a cooling effect. The energy efficiency ratio is extremely low and the energy saving effect is poor.
