Abstract

The invention provides an entrance guard, infrared and VRF air-conditioner indoor unit linkage control method. The method includes the following steps that S1, a door state and an infrared state of a room in an indoor unit air-conditioner area are detected; S2, the current room people number Num1 is calculated according to the change condition of the door state or the change condition of the infrared state; and S3, an air-conditioner indoor unit is controlled according to the current room people number Num1. According to the method, as the current room people number Num1 is calculated according to the change condition of the door state or the change condition of the infrared state, and the air-conditioner indoor unit is controlled according to the current room people number Num1, the condition of people in the room can be effectively judged, it is guaranteed that an air-conditioner is started only when someone is in the room, the energy consumption of the air-conditioner is effectively saved, and waste of electric energy is avoided.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to a linkage control method, system and device for access control, infrared and VRF air-conditioning internal units. Background technique [0002] Today, with the rapid development of science and technology, the access control management system is becoming more and more popular, and is widely used in the entry and exit of hotels and serviced apartments. By combining the access control management system with infrared sensing technology, the real-time number of people entering and leaving the room can be effectively monitored. VRF air-conditioning system (Variable Refrigerant Flow air-conditioning system), that is, variable refrigerant flow system, as the main source of energy consumption in hotels and serviced apartments, energy-saving control can effectively reduce room energy consumption, and at the same time in the economy Save running costs. At present, most of...
