Problems solved by technology

[0004] The heating effect and heating speed of the air conditioner are different under different compressor frequencies or different outdoor ambient temperatures, and these two compensation compensation control methods are relatively simple, and cannot reflect the current indoor temperature in real time. The disadvantage of delay causes the compressor frequency calculation to fail to meet the room heat load in real time, affecting user comfort

Embodiment

[0031] The air conditioner compressor starts running at 55Hz and keeps 55HZ unchanged. The outdoor ambient temperature is 2°C, the total compensation in heating mode needs to be 5°C, and each compensation value is 0.5°C. (The total compensation value is obtained through laboratory tests: in the laboratory test, the air conditioner is in the heating mode, the difference between the temperature value detected by the temperature sensor in the air conditioner room and the room air temperature. The total compensation value of the indoor temperature is obtained).

[0032] Calculate the compensation interval time by the formula:

[0033] Formula: △Time=K1 / compressor frequency×(K2-outdoor ambient temperature)×K3 (unit: second)

[0034] K1 is 60, K2 is 55, and K3 is 0.5.

[0035] Substitute the above parameter values ​​into the formula to calculate:

[0036] △Time=K1 / compressor frequency×(K2-outdoor ambient temperature)×K3

[0037] =60 / 55×(55-7)×0.5

[0038] =1.09×48×0.5

[0039]...

Abstract

The invention discloses a control method for indoor temperature compensation during heating operation of a variable frequency air conditioner. After a compressor is started, sectional cumulative compensation is adopted to cumulate an indoor temperature compensation value according to set interval time and a set temperature compensation step value until to a set indoor temperature total compensation value; the compressor stops when the indoor temperature reaches the set temperature, and the compensation value is returned to zero; the compensation is restarted after the indoor temperature is lower than the set temperature and the compressor is restarted. By using the sectional cumulative compensation method, the temperature in a room can be reflected more really. Thus, the frequency calculation of the compressor conforms to real room heat load well, so the temperature control of the air conditioner is more accurate and the comfort of a user can be improved.

Description

[technical field] [0001] The invention relates to a control method for frequency conversion air conditioner operation, in particular to a control method for indoor temperature compensation during heating operation of frequency conversion air conditioner. [Background technique] [0002] With the popularity of frequency conversion air conditioners, users have higher and higher requirements for air conditioners, especially for the comfort of air conditioners. Inverter air conditioners have the advantages of fast cooling / heating, high efficiency and energy saving, low noise, and high comfort, which greatly improves the performance of air conditioning. When the inverter air conditioner is running for heating in winter, the detection of room temperature will be affected by two aspects: one is the influence of the temperature of the evaporator; the other is that the hot air in the room is at the top and the cold air is at the bottom. The detected indoor temperature is higher than ...
