Abstract

Embodiments of the present invention provide a fan coil unit antifreeze control method, device and air conditioner, which relate to the technical field of air conditioners. The antifreeze control method for the fan coil unit includes: when the fan coil unit is powered on and the fan coil unit is in the power-on or standby state, controlling the opening and closing status of the water valve of the fan coil unit according to the actual measurement data of the fan coil unit, so as to prevent freezing water Flow into the coil of the fan coil or circulate the water medium in the coil of the fan coil. The fan coil antifreeze control method, device and air conditioner provided by the embodiments of the present invention can effectively control the antifreeze of the fan coil, improve the reliability of the use of the fan coil, prevent the coil from freezing due to improper use, and affect the use, and It can prevent the coil from freezing, cracking and water leakage, and improve the service life of the fan coil.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method and device for antifreezing control of fan coil units and an air conditioner. Background technique [0002] Fan coil unit is an air-conditioning system terminal device composed of fan blades, motors, and coils. It is widely used in the field of HVAC and is currently the most common indoor air-conditioning terminal device. It uses the fan to drive the indoor air to exchange heat with the chilled water or hot water (medium) flowing through the coil, thereby realizing the cooling / heating function. [0003] There are many types of fan coil units and a wide range of applications. However, most of the air-conditioning products on the market have not effectively controlled the antifreeze of the fan coil unit at present, or the optimal antifreeze method is not perfect, and the fan coil unit is likely to cause freezing and affect the use.
