摘要（英）：

The utility model discloses a heat supply network distribution energy consumption controller comprising a controller CPU (central processing unit), a 16-path AD (alternating current) interface, a 4-20 mA output interface, a water pump frequency output interface, a power switch, a stabilization chip, a pressure sensor, a temperature sensor, a circulating water pump, a variable-frequency controller and an electric three-way valve. According to the arrangement, input power is switched by the stabilization chip and then accessed to the controller CPU through the power switch. The pressure sensor and the temperature sensor are connected with the controller CPU through the 16-path AD interface. The controller CPU drives the electric three-way valve through the 4-20 mA output interface and is connected with the variable-frequency controller through the water pump frequency output interface. The heat supply network distribution energy consumption controller has the advantages that by means of indoor temperature teletransmission, water pump variable-frequency control, distribution energy consumption analysis and the like, heat supply is achieved according to requirements, the heat supply network distribution energy consumption is maximally reduced, energy utilization rate is improved, control precision is high, and management is convenient.
