Anti-condensation control system, air conditioner and anti-condensation control method

Abstract

The invention provides a condensation prevention control system, an air conditioner and a condensation prevention control method. The condensation prevention control system comprises a compressor, a first condensation branch, a second condensation branch and an evaporation branch; inlet ends of the first condensation branch and the second condensation branch are both connected with an outlet end of the compressor; outlet ends of the first condensation branch and the second condensation branch are both connected with an inlet end of the evaporation branch; the first condensation branch comprises a condenser, a filter and a first throttling mechanism connected in sequence; the second condensation branch comprises a switch valve and a second throttling mechanism connected in sequence; an outlet end of the evaporation branch is connected with an inlet end of the compressor; a humidity sensor and a first temperature sensor are arranged in an air return port of an indoor unit; and a second temperature sensor is arranged in an exhaust port of the indoor unit. The condensation prevention control system cannot generate the noise influence, is wide in application range, and in particular, is suitable for a fixed-frequency air conditioner incapable of adjusting a throttling valve element.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of air conditioning, and in particular to an anti-condensation control system, an air conditioner, and an anti-condensation control method. Background technique [0002] At present, most of the methods of anti-condensation of air conditioners in cooling or dehumidification mode are to reduce the frequency of the compressor, increase the windshield of the internal unit, lower the windshield of the external unit, and increase the opening of the throttling components, etc. Perform anti-condensation control. [0003] However, by changing the frequency or changing the windshield, it will not only bring noise impact, but also shorten the life of the motor. The method of increasing the opening of the throttling element is only applicable to the air conditioner with adjustable throttling element, but not applicable to the air conditioner with non-adjustable capillary or throttling spool. Con...
