[0002] The current high-temperature heat pump system uses a heat pump cycle, uses a compressor to compress the working fluid to a high pressure and temperature, and then heats the water to a high temperature through a heat exchange between the condenser and water, which affects the reliability of the compressor. The requirements are high, the power consumption of the compressor is large, and the COP of the system is low. The long-term operation has a certain impact on the life of the compressor due to the high exhaust temperature.
Moreover, the working medium required by this high-temperature heat pump is also relatively special, the price of the working medium is relatively high, and the investment is relatively large.

A high-temperature heat pump system with a vortex tube, including a compressor and a vortex tube connected to the exhaust pipe of the compressor, the high-temperature gas outlet end of the vortex tube is connected with the refrigerant inlet of a condenser with a water outlet, The low-temperature gas outlet of the vortex tube is connected to the refrigerant inlet of the condenser with a water inlet, the hot water outlet of the condenser is connected to the hot water inlet of the condenser, and the refrigerant outlet of the condenser is expanded by electronic expansion The valve is connected with the air supply port of the compressor, the refrigerant outlet of the condenser is connected with the liquid receiver, the liquid receiver is connected with the throttle valve, the finned evaporator, and the gas-liquid separator in turn, and the gas-liquid separator is connected with the The intake ports of the compressors are connected. After the air flow of the present invention passes through the vortex tube, part of the high-temperature and high-pressure gas exhausted by the compressor becomes a higher temperature and high-pressure gas, and the other part becomes a relatively low-temperature and low-pressure gas, and the water is heated to a higher temperature after the temperature is raised and the pressure is increased.
Description
technical field [0001] The invention relates to a high-temperature heat pump water heater, in particular to a high-temperature heat pump system with a vortex tube. Background technique [0002] The current high-temperature heat pump system uses a heat pump cycle, uses a compressor to compress the working fluid to a high pressure and temperature, and then heats the water to a high temperature through a heat exchange between the condenser and water, which affects the reliability of the compressor. The requirements are high, the power consumption of the compressor is large, and the COP of the system is low. The long-term operation has a certain impact on the life of the compressor due to the high discharge temperature. Moreover, the working medium required by this high-temperature heat pump is also relatively special, the price of the working medium is relatively high, and the investment is relatively large.
