The company has developed an energy-saving multi-source carbon dioxide heat pump hot water unit, which includes a hot water system and a multi-source system, a carbon dioxide heat pump system, and a heat pipe system; the multi-source system includes multiple heat source branches in parallel, and each heat source branch is set. There is a heat source, a valve and a first liquid pump; the carbon dioxide heat pump system includes a compressor, and the air outlet of the compressor is connected to the inlet of the gas-liquid separator through a gas cooler, a regenerator, a throttling mechanism, an air source heat exchanger, and a gas-liquid separator. The outlet of the gas-liquid separator is connected to the air inlet of the compressor through the regenerator; the heat pipe system includes a second liquid pump, a condenser and a solenoid valve connected in series; the heat pipe system and the carbon dioxide heat pump system are in the low heat source shared evaporator Heat exchange with multi-source system; hot water system exchanges heat with heat pipe system through condenser, and heat exchange with carbon dioxide heat pump system through gas cooler. The unit can maximize the use of natural heat sources, improve heat exchange efficiency, and has the characteristics of energy saving, environmental protection, and strong applicability.
