Air conditioner and fan linkage system and control method

Abstract

The invention discloses an air conditioner and fan linkage system and a control method. The air conditioner and fan linkage system comprises a fan and an air conditioner. An outdoor temperature sensor, an indoor temperature sensor and an air conditioner controller are arranged on the air conditioner. A fan controller is arranged on the fan. The signal output ends of the outdoor temperature sensor and the indoor temperature sensor are connected with the signal input end of the air conditioner controller. The air conditioner controller is connected with the fan controller. The fan and the air conditioner are separately installed. The startup and the shutdown of the fan are controlled through the air conditioner. The air conditioner can dynamically detect indoor temperature and outdoor temperature and can start up or shut down the fan according to difference between the indoor temperature and the outdoor temperature and the set indoor target temperature. The air conditioner additionally can set and control functions of the fan such as ventilation, startup and shutdown at a fixed period, can fully utilize outdoor cold and heat sources to decrease or increase the indoor temperature and can improve freshness and comfort of indoor air. Therefore, the air conditioner and fan linkage system has the advantages of energy saving, environmental friendliness, high economy and high practicability.

Description

technical field [0001] The invention belongs to the field of fans and air conditioners, and in particular relates to an air conditioner fan linkage system and a control method. Background technique [0002] At present, there are large temperature differences between day and night in many areas, coupled with rapid temperature changes, there are often weather phenomena with relatively large indoor and outdoor temperature differences. For example, in summer, when the indoor air temperature is 32 degrees or 30 degrees, consumers turn on the air conditioner to cool at night, set the indoor target temperature to 26 degrees, and the air conditioner is running at this time. However, due to changes in temperature, in many cases, the outdoor temperature has been lower than 26 degrees at this time, for example, the outdoor temperature is 24 degrees at this time. That is to say, there is no need to turn on the air conditioner for cooling at this time. Only through ventilation, taking a...

[0004] Or, the conventional fan system does not have the function of setting a fixed period of time to run. It often runs continuously without stopping after people leave. In fact, at this time, there is no problem with the temperature difference between indoor and outdoor and the freshness of the air, resulting in waste of power.
