Problems solved by technology

However, due to the existence of the measured temperature difference and the change of the frequency of the compressor, there will be a wave-shaped change in the room temperature
At the same time, based on the difference in ambient temperature, the difference between the indoor heat load and the cooling / heating output of the air conditioner is large, and high comfort cannot be achieved.

specific Embodiment

[0080] The current cycle acquisition Tp=15°C, Th=28°C, Ts=25°C;

[0081] Then ΔT1=28-25=3, ΔT2=25-15=10.

[0082] In the next cycle, obtain Tp=15°C, Th=27°C, Ts=25°C;

[0083] Then ΔT1=27-25=2, ΔT2=25-15=10.

[0084] At this time, f(ΔT2 / ΔT1)=(10 / 2-10 / 3) / t=0.17, while f(ΔT2)=(10-10) / t=0, f(ΔT1)=(2-3) / t=-0.1, t is taken as 10min. Belongs to (+, 0, -), at this time, the cooling capacity of the air conditioner is excessive, and the frequency reduction operation is required. The frequency adjustment parameter is calculated according to f(S)×|f(ΔT2 / ΔT1)|, where f(S) represents the current frequency. If the current frequency is 50Hz, the frequency will be reduced by 9Hz. At this time, the frequency adjustment value will be rounded up.

[0085] For ease of understanding, the following table lists the judging conditions and corresponding frequency adjustment methods in the heating mode of the embodiment of the present invention, where illogical combination items are not shown in ...

Abstract

The invention provides a control method and device of the temperature comfort of an air conditioner and the air conditioner, and relates to the technical field of air conditioners. The control methodcomprises the steps of periodically collecting data including the set temperature of the air conditioner, the temperature of an indoor unit coil of the air conditioner and the indoor environment temperature of a room; respectively solving the first derivative of the first temperature difference, the second temperature difference and the ratio of the temperature difference at a first time interval,wherein the first temperature difference is the difference between the indoor environment temperature of the room and the set temperature of the air conditioner, the second temperature difference isthe difference between the set temperature of the air conditioner and the temperature of the indoor unit coil of the air conditioner, and the ratio of the temperature difference is the ratio of the second temperature difference to the first temperature difference; determining whether the heat load of the room and the output of the air conditioner are balanced according to the value of the first derivative; and controlling an compressor to change the frequency if the heat load of the room and the output of the air conditioner are balanced. According to the control method, the principle of heatbalance is utilized, the room temperature is accurately adjusted according to the value of the first derivative of key parameters, and the control over the comfort of the room temperature is realized.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a method and device for controlling the temperature comfort of an air conditioner and an air conditioner. Background technique [0002] With the popularization of air-conditioning and the development of air-conditioning technology, people have higher and higher requirements for the comfort of air-conditioning to adjust the room temperature, and various new-concept air-conditioning comfort operation modes emerge in endlessly. Create a comfortable working and living environment by controlling the temperature to make the human body feel comfortable. [0003] The temperature control of existing air conditioners mostly uses temperature difference to adjust the room temperature, that is, adjusts the frequency of the compressor according to the temperature difference between the set temperature and the ambient temperature, and then realizes the stability of the room tem...
