Abstract

The invention relates to a variable air volume terminal system and control method capable of achieving automatic switching of running working conditions. The variable air volume terminal system comprises a variable air volume terminal box, an air volume adjusting valve, an air volume sensor, a variable air volume terminal controller and a temperature sensor; the air volume adjusting valve, the airvolume sensor and the temperature sensor are connected with the variable air volume terminal controller separately; the air volume adjusting valve is arranged in the variable air volume terminal boxand used for adjusting the air volume; the air volume sensor is arranged in the variable air volume terminal box and used for collecting the air supply volume; the temperature sensor is used for detecting the indoor temperature and the air supply temperature; and the variable air volume terminal controller is arranged outside the variable air volume terminal box and used for receiving the indoor temperature, the air supply temperature and indoor set temperature information and controlling a variable air volume terminal to switch the running mode. By adopting the scheme, the working efficiencycan be effectively improved, the accuracy set by the system working conditions is improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of automatic control of HVAC, and in particular relates to a variable air volume terminal system and a control method for automatic switching of operating conditions. Background technique [0002] Variable air volume air conditioning system, also known as VAV system (Variable Air Volume System), is an air conditioning system that adjusts the indoor temperature and humidity environment by changing the air supply volume; in the variable air volume air conditioning system, several variable air volume terminals are installed in each room or area. The device (VAV-BOX), the variable air volume terminal device can adjust the air supply volume according to the indoor temperature and the set value, ensure the temperature control accuracy in the room, and at the same time reduce the fan energy consumption of the air conditioning unit. Because of its good indoor air quality, obvious energy saving at partial load, and flexible co...
