Power control method, power control system, gas-liquid separator and air conditioner

Abstract

The invention provides a power control method, a power control system, a gas-liquid separator and an air conditioner. The power control method comprises the following steps of judging whether the working condition temperature of the gas-liquid separator is greater than zero DEG C; and determining the power value of an electric heating pipe according to the working condition temperature judgment result. The power control method comprises the following specific steps: if judging that the working condition temperature is not greater than zero DEG C, determining a preset working condition temperature, which corresponds to the working condition temperature, in a preset power control table, so as to determine a reference power value corresponding to the working condition temperature, wherein the preset power control table comprises one-to-one correspondence relation between the preset working condition temperatures and reference power values; determining a power value according to the reference power value and a preset power coefficient, and driving the electric heating pipe to operate at a power value. According to the technical scheme, intelligent optimization control over the power of the electric heating pipe of the gas-liquid separator is realized, and the reliability of the electric heating pipe and the gas-liquid separator can be enhanced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a power control method, a power control system, a gas-liquid separator and an air conditioner. Background technique [0002] In the related art, the gas-liquid separator is widely used in air conditioners. It is installed before the air inlet of the compressor to prevent the compressor from sucking too much liquid and causing liquid shock. The refrigerant enters into the Gas-liquid separation is carried out in the gas-liquid separator. [0003] However, when the air conditioner is operated in a low-temperature environment, due to the low outdoor ambient temperature, the refrigerant is not completely evaporated during heating operation, and a large amount of gas-liquid mixture flows into the gas-liquid separator. At this time, part of the refrigerant is not completely evaporated, so the temperature If the temperature is too low, the heat transfer is not complete and evap...

Problems solved by technology

[0003] However, when the air conditioner is operated in a low-temperature environment, due to the low outdoor ambient temperature, the refrigerant is not completely evaporated during heating operation, and a large amount of gas-liquid mixture flows into the gas-liquid separator. At this time, part of the refrigerant is not completely evaporated, so the temperature If the temperature is too low, the heat transfer is not complete and evaporates into superheated gas. This part of the gas-liquid mixture that is not completely evaporated also affects the discharge temperature of the compressor after compression, resulting in a low temperature of the high-pressure gas discharged fr...
