Embodiment 1
[0024] Embodiment 1: The first kind of system composition and connection mode, such as figure 1 As shown, a new jet heat exchange unit is mainly composed of a jet heat pump, a water-to-water heat exchanger WEX and a waterway system. The jet heat pump is mainly composed of a generator G, a condenser C, an evaporator E, an ejector EJ, Working fluid circulation pump P R , regenerator IEX, liquid storage tank S, throttling device V R and connecting pipelines.
[0025] Heat pump working fluid process: The heat pump liquid working medium is heated by the water supply of the primary side pipeline in the generator G to become the heat pump working medium vapor, and then enters the ejector EJ to speed up and reduce pressure, and injects the low-pressure superheating work from the regenerator IEX After the steam of the two working fluids is combined, decelerated and pressurized, it enters the condenser C and is condensed into a liquid by the return water from the secondary side pipeli...
Embodiment 2
[0029] Embodiment 2: the second kind of system composition and connection mode, such as figure 2 As shown, a new jet heat exchange unit is mainly composed of a jet heat pump, a water-to-water heat exchanger WEX and a waterway system. The jet heat pump is mainly composed of a generator G, a condenser C, an evaporator E, an ejector EJ, Working fluid circulation pump P R , regenerator IEX, liquid storage tank S, throttling device V R and connecting pipelines.
[0030] Heat pump working fluid process: After the heat pump liquid working fluid is heated by the water supply in the primary side pipeline in the generator G and turned into working fluid vapor, it enters the ejector EJ to speed up and reduce pressure, and injects the low-pressure superheating working fluid from the regenerator IEX. After the two-way working medium steam merges, decelerates and pressurizes, it enters the condenser C and is condensed into a liquid by the return water from the secondary side pipeline, an...
Embodiment 3
[0034] Embodiment 3: the third kind of system composition and connection mode, such as image 3 As shown, a new jet heat exchange unit is mainly composed of a jet heat pump, a water-to-water heat exchanger WEX and a waterway system. The jet heat pump is mainly composed of a generator G, a condenser C, an evaporator E, an ejector EJ, Working fluid circulation pump P R , regenerator IEX, liquid storage tank S, throttling device V R and connecting pipelines.
[0035] Heat pump working fluid process: After the heat pump liquid working fluid is heated by the water supply in the primary side pipeline in the generator G and turned into working fluid vapor, it enters the ejector EJ to speed up and reduce pressure, and injects the low-pressure superheating working fluid from the regenerator IEX. After the steam of the two working fluids merges, decelerates and pressurizes, it enters the condenser C and is condensed into a liquid by the hot water from the secondary side pipeline, and ...
