Strength of Air- or water-source heat pumps that use CO2 as a refrigerant
The 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, and the controller includes a temperature sensor, which is arranged on the carbon dioxide heat pump and is used to detect each key point temperature; 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; low pressure pressure control, which is set at the compressor inlet, detects whether the carbon dioxide heat pump pressure is lower than the set 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.
A carbon dioxide heat pump sludge drying system, the carbon dioxide heat pump sludge drying system includes: a sludge drying unit, the sludge drying unit is used for drying the sludge to obtain dried sludge and moist hot air; and a carbon dioxide heat pump A unit, the carbon dioxide heat pump unit is used for forming the humid and hot air flowing into the carbon dioxide heat pump unit from the sludge drying unit into dry high temperature air, and then returning the dry high temperature air to the sludge drying unit , the dry high temperature air is used as a heat source for drying the sludge. The utility model adopts a supercritical CO2 heat pump unit, the exhaust temperature of the compressor is high, the latent heat of CO2 is high and non-condensing, so the temperature of the hot air outlet can reach above 100 ° C, and the drying efficiency is greatly enhanced
The carbon dioxide heat pump series multi-tank direct heat heating system includes: a carbon dioxide heat pump unit and a water tank, and is characterized in that: the water tanks are several and are connected in series with each other, and a cut-off valve is arranged between two adjacent water tanks; The water outlet of the heat pump unit is connected with the first water tank, and the return water port of the carbon dioxide heat pump unit is connected with the terminal water tank; the water outlet of the first water tank is connected with the water inlet of the heating equipment, and the terminal water tank is connected with the water inlet of the heating equipment; A tap water supply branch is also provided on the water supply branch between the carbon dioxide heat pump unit and the first water tank. The utility model has simple structure, convenient installation and adjustment, improves the stability of the unit, reduces maintenance and material costs, and improves the heat exchange efficiency of the transcritical carbon dioxide heat pump heat exchanger.
