The company has developed a carbon dioxide heat pump controller. The carbon dioxide heat pump includes a compressor, a fan, a water pump, an electronic expansion valve, a three-way valve, an evaporator and a heat exchanger. The controller includes a temperature sensor, which is arranged on the carbon dioxide heat pump and uses It is used to detect the temperature of each key point; the high pressure pressure control, which is set at the compressor outlet, detects whether the pressure of the carbon dioxide heat pump exceeds the set upper limit and sends a signal to the MCU; the low pressure pressure control, which is set at the compressor inlet, detects whether the pressure of the carbon dioxide heat pump is low. It is used to set the lower limit and send a signal to the MCU; the relay drive module is used to control the compressor, the fan and the three-way valve; the water pump drive module is used to adjust the speed of the water pump; the electronic expansion valve drive module is used to drive the electronic expansion valve. The controller effectively solves complex problems such as high cost of the control system, intelligent fault diagnosis and energy-saving and efficient operation, and makes the controller system more optimized through real-time analysis and processing of data.
