Problems solved by technology

When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affects the user experience

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner operation control method. In order to balance a relationship between air quantity of the outdoor fan and an outer coiled tube temperature, the air conditioner operation control method disclosed by the invention comprises the following steps: in an air conditioner heating operation process, detecting a temperature t-upper of the upper part of an outer coiled tube and a temperature t-lower of the lower part of the outer coiled tube every preset time; if a dew-point temperature and t-lower is greater than or equal to t-upper and smaller than or equal to a dew-point temperature, controlling rotation speed of the outdoor fan to be second rotation speed, and reducing compression frequency of the air conditioner by preset percentage, wherein second rotation speed is equal to subtracting 50 revolutions from first rotation speed, and the first rotation speed is rotation speed while the outdoor fan is on the highest gear. The method disclosed by the invention can balance the air quantity of the outdoor fan and the outer coiled tube temperature, so that operation efficiency of theair conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an operation control method of an air conditioner. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and ...
