Abstract

The invention provides a variable frequency air conditioner and a frequency control method thereof. The variable frequency air conditioner comprises an indoor machine part, an outdoor machine part, and a frequency setting device and a frequency display device which are connected with the indoor machine part, wherein the indoor machine part and the outdoor machine part are connected by a connecting wire. The frequency control method includes the following steps: running a set frequency and displaying the running frequency; monitoring and correcting the running frequency. Under the conditions of proper indoor environmental temperature, set temperature and indoor evaporator temperature, the variable frequency air conditioner and the frequency control method thereof of the invention allow a user to artificially set the running frequency of the air conditioner by the frequency setting device, enables the energy efficiency of the variable frequency air conditioner to be furthest played and can not damage a compressor; besides, the user can control the current actual running frequency of the air conditioner; therefore, the invention has the advantages of energy conservation and humanization.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an inverter air conditioner and a frequency control method thereof. Background technique [0002] Air conditioner is a widely used air conditioning equipment, the main function is to adjust the temperature and humidity of the air. Compared with ordinary fixed frequency air conditioners, inverter air conditioners have the advantages of energy saving and comfort. The frequency of the DC compressor of the inverter air conditioner is adjustable, and the frequency control of the compressor plays an important role in its control technology field. In the prior art, the operating frequency of the compressor of the inverter air conditioner is automatically controlled. In the process, the indoor ambient temperature, outdoor ambient temperature, and user-set temperature are generally used as the parameters and basis for control. Although this automatic control method reduces the user's trou...
