Anti-condensation control method, device and air condition system used for fixed frequency unit

Abstract

The invention discloses an anti-condensation control method, device and air condition system used for a fixed frequency unit. The method includes detecting the evaporation temperature of a refrigerant agent in the fixed frequency unit in a refrigerating mode; performing fuzzy inquiry calculation on the detected evaporation temperature based on a pre-set fuzzy relation database so as to obtain a corresponding calculation result, wherein the fuzzy relation database includes the fuzzy relation between the evaporator temperature of the fixed frequency unit and the corresponding indoor environmental temperature; judging whether to perform anti-condensation control over the fixed frequency unit based on the calculation result; enabling the fixed frequency unit to enter a predetermined anti-condensation control mode when the judgment result shows that anti-condensation control over the fixed frequency unit is needed so as to realize the anti-condensation control over the fixed frequency unit. The scheme provided by the invention can overcome shortcomings of use inconvenience, large potential safety hazards and poor user experience and the like of the prior art and can achieve beneficial effects of use convenience, small potential safety hazards and good user experience.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning control, and in particular relates to an anti-condensation control method and device for a fixed-frequency machine, and an air-conditioning system. Background technique [0002] A fixed frequency air conditioner is a fixed frequency machine, which is a unit used to provide a space area (generally a closed space) to deal with changes in air temperature. In order to pursue low noise and comfort, the current fixed-frequency machines set the speed of the lowest operating wind gear of the indoor unit relatively low, because the fixed-frequency machine only has a frequency of 50HZ, so when running at the lowest wind gear, the outlet air temperature is very low. Low, it is easy to form serious condensation around the air outlet, and when the condensed water around the air outlet reaches a certain amount, it will drip down (especially the air conditioner air deflector at the outlet, when it is se...
